Well Managed Animal & Livestock Nutrition As Part Of A Low Carbon Future

by Eduardo Martinez

Of many discussions around Global Warming and the subject of greenhouse gas emissions (GHG), the majority are focused on causes like energy production or transportation emissions, and most of those emissions are carbon dioxide.  According to EPA’s 2016 Report, Inventory of U.S. Greenhouse Gas Emissions and Sinks, electricity production and transportation produced over 56 percent of the greenhouse gas emissions in the United States.

In addition to those well known causes, agriculture and livestock production also contribute significant amounts of greenhouse gas emissions.  The three main GHG emitted by the agriculture and livestock sector are nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) emissions, as well as losses of nitrogen (N), energy and organic matter that undermine efficiency and productivity in agriculture.

The greatest opportunity for reduction of GHG emissions in the livestock sector lie with improving the efficiency with which producers use natural resources (think tractor fuel) engaged in producing plant protein for animal production, to manage the cost per unit of edible or non-edible output. These improvements are always being pursued in the interest of increasing yield, enhancing quality, or reducing production costs, all while providing a safe and affordable food supply to the public.

There is an obvious and direct correlation between GHG emission and carbon intensities and the efficiency with which producers use natural resources. But among possible opportunities for reducing GHG emissions, fascinating breakthroughs lie in improving livestock nutrition efficiency at the unit level—in this case—the cow level. The average cow emits around 250 liters of methane per day and ruminants overall (animals like cattle, goats and sheep) contribute about 25% of all anthropogenic or man-made methane emissions.

Today universities and industry are working closely together in many ways to improve cattle production and efficiency by eliminating waste, applying the latest enzyme research to improving ruminant digestion and protein conversion. They are also introducing alternative forms of plant protein that might also be more sustainable than traditional energy-intensive animal feedstocks like soy or corn.

For example, recent studies have identified how livestock diet can affect or minimize methanogenesis — methane production.  One common misunderstanding on playgrounds across America is that the back end of the cow is the prime offender in producing GHG in the form of methane. But the truth is the vast majority of methane comes from the cow’s burp—over 95%, in fact!  Thus the opportunity for improvement lies earlier in the animal’s digestive tract.

Rocky De Nys, Professor of aquaculture at James Cook University in Townsville, Australia, has been studying the effects that introducing seaweed to a cow’s diet can have on methane production.  Specifically, Professor De Nys and his team discovered adding a small amount of dried seaweed to a cow’s diet can reduce the amount of methane a cow produces by up to 99 per cent.  The species of seaweed is called Asparagopsis taxiformis, and JCU researchers have been actively collecting it off the coast of Queensland.

“We had an inkling that we would get some success from this species, but the scale or the amount of success and reduction we saw was very surprising,” he said, adding “methane gas was the biggest component of greenhouse gas emissions from the agriculture sector.” The key aspect of Asparagopsis taxiformis is that it produces a compound – bromoform (CHBr3) – which prevents methane production by reacting with vitamin B12 at the final step, disrupting enzymes used by gut microbes that produce methane gas as waste during digestion.

Advances such as these are critical to increasing sustainability in the farm and livestock industry and reducing the carbon intensity of farming and producing our global food supply.  TerViva is providing forward thinking solutions in the form of our tree-based platform for producing plant protein and vegetable oil, Pongamia pinnata.

TerViva’s Pongamia tree produces 3 times the plant protein per acre than soy (3 tons vs 1 ton) and 10 times the vegetable oil per acre than soy (400 gal. vs 40 gal.) and all without the negative environmental impact and carbon intensity of annual row crops. Permanently installed orchard crops like Pongamia trees provide tremendous opportunities for carbon sequestration that offset anthropogenic GHG starting with the obvious visible form of the tree visible to the eye, and also from the deep and stabilizing root system below ground.  Pongamia is also a nitrogen fixing legume that takes atmospheric Nitrogen and returns badly needed (N) to the soil.

In the next 12 months, TerViva will be modeling the exact amount of carbon sequestered by our trees per acre, and therefore, the exact amount of carbon reduction that our protein meal offers as compared to soybean.  I’d bet that we’ll find our protein meal offers a compelling advantage over soybean meal in terms of greenhouse gas reduction overall.

Add these sustainable characteristics to the numerous high value products that Pongamia trees yield, and to top it off, a nice shady canopy to host a songbird’s nest or to provide some welcome shade to cattle or sheep on a hot, sunny day and you’ve got a winning addition to tomorrow’s sustainable farming portfolio.

Wild relatives may not be so crazy after all

by Madison Brown

Recently, I came across an article pertaining to a study done on the use of ‘Crop Wild Relatives.’ This study analyzed the wild relatives of crops widely used across the globe to analyze qualities such as drought-tolerance and heat resistance, amongst other more desirable traits plant breeders seek out as our climactic patterns continue to become less and less predictable.

Climatologists and weather forecasters are already calling for another El Nino event to begin this fall. El Nino typically brings weather extremes such as abnormally rainy, warm winters and dry summers. In the world of food production, this means crops struggle to survive respective seasons. For consumers, this can lead to shortages of their favorite fruits and vegetables and in the worst-case grains and other staple crops. In turn, this leads to shortages of livestock feed. These threats result in plant breeders and researchers to investigate ‘wild’ relatives to these crops that in their current form may have lost the ability to adapt.

Staple crops such as rice, barley, chickpea and sunflowers were all analyzed throughout said study. The crops analyzed in this study are major sources of carbohydrates, plant-based protein (legumes) as well as oils and are cultivated consistently throughout the world. By providing information pertaining to commonly cultivated crops, their ‘cousins’ so to speak can be analyzed to provide further understanding of said crops genetics and how the variability can provide both good and bad references of its behavior and survival in the future, or potential improvements to current cultivars. It seems the overall goal here is to increase biodiversity. However, this study left-out major oil crops such as soybeans and corn, which are responsible for ethanol, bio-diesel and other petroleum alternatives that continue to increase in utilization every year.

This article and the information it presented is compelling because our team has been applying these same principles in a process to domesticate Pongamia Pinnata, a native to India and Australia and a wild, tropical relative to legumes we consume and utilize in industrial processes every day. Native to the tropics, Pongamia is naturally drought and tolerant to most temperature and weather extremes. Considering current predictions of our climate and weather patterns for the future, Pongamia seems to fit the bill as a “Wild Relative” for future oilseed crop production.

However, Pongamia is vastly different in that it is a tree crop, thus providing other major environmental benefits to our planet. One benefit is carbon sequestration as all trees consume significantly larger amounts of CO2 to complete photosynthesis. In addition, Pongamia is a legume – meaning it “fixes” its own nitrogen through a symbiotic process involving tiny organisms living in the soil. These organisms are called Rhizobia and they participate in a symbiotic relationship with their host by feeding on photosynthates (carbohydrates and sugars provided by photosynthesis), whilst providing nitrogen to their host. Nitrogen also happens to be the most limiting nutrient to plant growth.  With these characteristics, Pongamia can provide us with a clean, forward-thinking alternative to soybeans and other oilseed crops.

Overall, it is both refreshing and exciting to learn other scientists and organizations are performing similar research to ours, on the same path to increasing sustainability and biodiversity on this beautiful planet we call home.

Keep Edible Oils for People, and Non-edible Oils for Industry

By Tom Schenk

In 2012, actor Matt Damon starred in a movie “Promised Land”.  The story was about a rural community whose water was being contaminated from chemicals used in the injection fluids from a petroleum company’s nearby oil and natural gas fracking operation.  While the movie was a box office flop for Damon, it did raise the public’s awareness about the toxic cocktail of chemicals (benzene, toluene, xylene, and ethylbenzene, and methanol, to name a few) that are combined with the large quantities of water (up to 7 million gallons) and sand that are injected deep underground at high pressures to fracture and open up rock formations so oil and gas can flow to a well. These chemicals help to reduce corrosion of the well, lubricate the extraction process, and prevent clogs and bacterial growth.

fracking

Many studies have claimed that these chemicals were used in such small quantities that they posed little risk to aquifers and other groundwater sources. Nevertheless, the movie, numerous articles, and academic studies raised the public’s awareness about some of the potential dangers created by this new drilling technology.  And no doubt it also raised alarms in the oil and gas companies’ legal and risk management departments that contaminating the water supply of one or more cities would wipe the company off the map.

Guar gum has been used in the food industry for many decades.  It has also been one of the favorite products drillers used to hold that sand in suspension and deliver it to its destination.  The greatest source for guar gum historically has been India.  The boom in fracking has created monumental price spikes and shortages for drillers in obtaining this product and has created havoc on their P&L’s.

In recent years, ExxonMobil, Halliburton, and a myriad of other oil-related companies have been developing suitable alternatives – often from plant-based oils – for developing greener, more environmentally-friendly lubricants for their drilling activities.  They would also like to see a more dependable domestic supply for the ingredients in their fracking recipes for biodegradable polymers.

However, in the fast developing world of biodegradable polymers, drilling fluids are almost a rounding error by comparison to all the other wonderful consumer and industrial products that technology that is developing from plant-based oils such as marine oils, auto and aviation lubricants (often with superior wear and heat properties), surfactants, detergents, shopping bags, food containers and countless other products where petroleum-based products and plastics have historically dominated. This technology is in a profound growth phase as almost anything we currently know as plastic can be reproduced in a more sustainable manner with plant-based oils rather than petroleum. And it sells because the consumer wants it.

Soy is the most dominant feedstock for many of these renewable products, as well as corn, canola, flax, palm, cottonseed, peanut, and others that are cultivated in large quantities worldwide.  Couple the growth in biofuels with the growth in this new technology for industrial applications, and all it will take is one or two bad years of crop production for there to be be a collision between food security for people and feedstock supply for factories and refineries.

Only the most arable lands – which are in diminishing supply – should logically be devoted exclusively to food.  Champions of these earth-friendly fuels and industrial products made from renewable feedstocks are missing the full picture.  They should be calling for the development of high-yielding non-edible oilseed crops that can thrive on the marginal land!

This is Terviva’s mission.  One of the most promising crops in this space is the wild tree called pongamia that our company is commercializing. These oilseed trees can produce up to 10x the amount of oil per acre that the best soybean land in Iowa can produce. Carbon is sequestered, and vast fallow acreage in Florida and Hawaii is on its way to becoming annually renewable – and profitable -“oilfields”.  Hardy, high-yielding crops on marginal lands are the optimum way to achieve peak biodiversity. Leave the good lands to make food for people.

Climate Changes Role in the Syrian Uprising

Happy 2016! This is a recent post that Adam put up on ecosciencewire.com

By: Adam Hanbury-Brown

Three years before Syria’s uprising in 2011, the country experienced the worst drought in recorded history. This unprecedented dry weather caused dramatic crop failure and livestock mortality in regions heavily dependent on agriculture. The drought was so severe that one and a half million Syrian farmers were forced to relocate to the outskirts of large cities– constituting a wave of internally displaced people who would later experience further hardships and civil unrest.

A recent study published in the Proceedings of the National Academy of Sciences (PNAS) shows that the Syrian drought was most likely exacerbated by human-caused climate change, and that these extreme weather events will be two to three times more likely in the future. The authors of this paper, Colin P. Kelly of UC Santa Barbara, Shahrzad Mohtadi of Columbia University, and their colleagues, insightfully connect the dots between human-driven climate change, the recent drought, and the Syrian uprising in March, 2011. They tease apart complex climate factors to show that climate change likely had a strong impact on the drought. Most importantly, this study serves as a reminder that climate change doesn’t need to kill directly to cause suffering. It only needs to be the tightening vice around our preexisting vulnerabilities: geopolitical instability, unsustainable agricultural policies, and disparities in wealth.

Vulnerable. That is best way to describe Syrian agriculture as the drought descended in 2006. Unsustainable agricultural policies under Hafez al-Assad (1971-2000) led to the depletion of Syrian groundwater prior to the drought. If managed more sustainably this might have ameliorated the water shortages. On top of that, the country had not yet fully recovered from the drought of the 1990s.

As the drought continued to displace farmers, internal refugees came to constitute twenty percent of Syria’s total urban population. Prices of wheat, rice, and feed doubled and this only served to exacerbate resource constraints in urban areas. Bashar al-Assad ignored the growing issues of overcrowding, poor infrastructure, unemployment, and crime- all factors that contributed to the unrest that led to the civil war.

In order to understand climate change’s role in the drought, and subsequently the uprising, the authors analyzed long term trends in precipitation and temperature. Essentially, Syria is getting hotter and drier in accordance with the pattern predicted by increasing greenhouse gas. Seven of the eleven years between 1998 and 2009 received less rainfall than the 1901-2008 normal. The authors also point out that “three of the four most severe multi-year droughts have occurred in the last 25 years”– the era of most intense human impact on climate. Climate change is believed to be increasing sea-surface pressure in the eastern Mediterranean which is suppressing westerly winds that typically bring rain to Syria.  More alarming is that the authors cite a study which, “using a high-resolution model able to resolve the complex orography of the region concluded that the FC [Fertile Cresecent], as such, is likely to disappear by the end of the 21st century as a result of anthropogenic climate change.” It is deeply depressing that civilization will likely destroy its own birthplace.

If connecting the dots between the Syrian crisis and climate change still seems like a leap of faith, just return to Jared Diamond’s book, Collapse, (which incidentally was published in 2005– the year before the Syrian drought started). Diamond’s account of the fall of the Anasazi Empire in the southwest of the United States around 1120 AD is an uncannily similar story. The Anasazi were a people accustomed to living in a dry landscape. Their agricultural practices worked for a period of time, but just like the Syrians, they employed techniques that lowered groundwater levels-leaving them vulnerable to drought. Before the Anasazi groundwater issue came to a head, their civilization prospered, and a ruling elite developed in city centers. Goods and food flowed in to the centers from the agrarian periphery. In 1117 AD the Anasazi experienced a severe drought that is believed to have led to severe strain on the agricultural system. Around the same time, walls and other fortifications were erected around the city centers– marking a period of civil unrest and warfare. It is believed that the farmers, forced to abandon their land, no longer tolerated the ruling elite, and the civilization fell into disarray. Archaeologists found scalped skulls and unburied bodies in the grand houses of the ruling elite from this time.

The similarities between the Anasazi and the Syrian crisis are clear. What’s different about the Syrian crisis today is that the weather events are no longer just forces of nature. Humans are exacerbating the climatic pressures that we have seen play a role in civil unrest and warfare. The 2011 drought in Russia caused a spike in food prices- a major cause of the Egyptian uprising. Recent reporting on Russia’s current drought notes that “it’s among the worst ever recorded”– words that feel surprisingly familiar when it comes to weather events these days. Let’s hope history doesn’t repeat itself… but surely it will.

Diversity

Written By Lila Taheraly

I have always thought that diversity is key.

My parents come from two different continents.

I grew up watching the French National soccer team winning the World Cup in 1998 and the European Cup in 2000 with the slogan “Black, Blanc, Beur” referring to the three different skin colors of the players.

Diversity is everywhere.

Try to find two identical papayas at the farmers market.

Try to handwrite the same word exactly the same way.

Even twins have different moles or different eyebrow lines.

Diversity is life.

So when I read this article published in Nature Plants in April 2015, I felt happy. Diversity could also be great in agriculture. It could be promising and profitable!

What did these researchers do?

For one year, they grew five different grassland species on 124 small plots, half of which were exposed to drought during six weeks. The plots received either monocultures or polycultures and displayed different degrees of genetic diversity. The configuration allowed them to study separately the influence of species diversity and the influence of genetic diversity on biomass production and on temporal stability of the production.

Researchers harvested six times during the year, weighed their harvest and compared the results.

Their results proved that polycultures produced more than monocultures, especially when subject to drought, regardless of the number of genotypes per species present. With irrigation, plots with several species presented a superior yield of 200g/m² than plots with one species, i.e. 0.8tonne/acre. For plots under drought conditions, the difference was 3.2tonnes/acre.

Conversely, the temporal stability of production increased only with the number of genotypes present under both drought and non drought conditions, and was unaffected by the number of species.

How do they explain these results? With diversity, plants are more likely to produce their peak biomass at different dates. This process is called growth asynchrony. They will use water and nutrients at different moments. They will share the available resources more easily.

The article shows that species diversity and genetic diversity can play different roles for livestock optimization: species diversity impacts biomass production especially under drought conditions and genetic diversity impacts production stability. Both could be considered in agronomic systems to increase the productivity and resilience, especially in a context of rising hazardous environmental events.

We can notice that this is not the main direction that global agriculture followed for the last fifty years. The great news is that the tools that have been developed to improve monocultures for decades could help today to define and improve species mix which would increase yields and better resist hazardous conditions.

Maybe diversity could also be agriculture’s opportunity.

Understanding Global Agriculture in 15 Minutes

By Tom Schenk, Director of Business Development

Over the past ten years, scores of articles have been written about the merits of investing in farmland as well as the challenges of producing enough food to feed a population that is growing at the rate of about 80 million per year at the same time arable farmland is diminishing.  To put that in perspective, that is like producing the population of Germany – annually!  Worldmapper.org has done an excellent job of producing world maps that show the relative size of each country in relation to various data sets they are analyzing.  The following five maps will be helpful in illustrating the challenges of feeding the world.

Before we begin, here’s the color-coded world map to use as a point of reference:

LandArea

Now, here’s how the world should look if a country’s land mass was proportional to its population:

Land2Pop

Now that we have a sense of how populations are distributed, let’s consider food.  The most basic measure of food is to considerer cereal grains because they are a major food staple and feed livestock and poultry.  Here’s what the world would look like if each nation’s boundaries were proportional to the cereal grain they produced:

Land_Cereal

Nevertheless, the above map doesn’t give us an idea if the cereal grains they produce are adequate enough to feed their populations.  So let’s look at net cereal grain imports:

Cereal_Imports

So then, which countries are exporting all the grain these countries are importing?

Cereal_Exports

Africa, the Middle East, SE Asia and China cannot feed themselves. Depending on which side of the fence you are on, it is now becoming easier to see the challenge – or the opportunity – for US agriculture. To understand the limiting factors in keeping the world fed, there’s no better place to begin than the soils.  Since about 6000 BC when tribes began to congregate along the Nile, man has been able to transition from being a hunter/gatherer to creating stationary communities that could produce more food than they needed and thus was the beginning of trade.  And it was also often one of the core causes of war throughout the history of civilization.

Not all soils are created equal, and good soils are certainly not always found where they are most needed.

GlobalSoils

The two best soils are Mollisols and Alfisols followed by Ultisols and Oxisols.  These last two soil types, even with considerable additional inputs of fertilizers and lime however, still cannot match the productivity of the first two soil types.

Examine where these four soil types are distributed around the globe.  You will see that these soil types are generally distributed along temperate growing zones and moderate elevations and rainfall. It is also interesting to note that most of the major world powers throughout history are located within these zones, but that’s a discussion for another day.

What these maps show is that the US has the single largest contiguous mass of the best soils in the world.  Though it accounts for only 6.7% of the world land mass, it contains 21% of the worlds Mollisols and 10% of the Alfisols.  The icing on the cake is that within these productive soil areas is a network of navigable waterways and ocean ports.

The Ukraine has great soils, but poor transportation infrastructure.  Canada has good soils, but also a shorter growing season and long transportation distances.  Brazil is blessed with an abundance of productive soils, but a coastal mountain range creates logistical nightmares of transporting grain from the interior via bumper-to-bumper trucks that clog the roads at harvest time.  They have no rivers near any productive agricultural land on which they can barge the grain or railroads they can ship it on.  You see, for every quarter percent of slope on a mountain grade, the weight a locomotive can pull is reduced by 50%!  Several miles of grain laden Brazilian trucks could easily fit on a single Mississippi River barge.  It is one thing to have transportation capabilities but another to have efficient (read cheap) transportation capabilities.

Two challenges worth mentioning in the US are water and farmers.  Almost every significant aquifer in the US is being depleted.  Advances in ag technology and irrigation efficiencies need to be more rapidly utilized. The proliferation of irrigation wells from Florida to Washington State has exceeded the recharge capacity of the aquifers. In the first 5 months in 2015, 1800 California wells have gone dry in the midst of a relentless drought.

Considering all the challenges of feeding the people on this earth, it is difficult to imagine a more noble profession.  However, there is an alarming shortage of young people going into farming.  The average age of an American farmer is 57 years old.  The Young Farmers Success Act bill was recently introduced to the US House of Representatives.  This bill would recognize farmers, ranchers, and farm employees to be eligible for Federal Service Loan Forgiveness program that is currently available to doctors, nurses, teachers, and government employees.  This program forgives loan balances after 10 years (120 payments).

On this last point, there is an important intangible many people in agriculture have pointed out to me.  In contrast to, say, Latin America where modern production farming is a phenomenon of the last 30 years, most multi-generation family farms in the US  have a legacy of understanding, conservation, and environmental care for the land that produces long-term efficiencies that few others in the world can match.

Grazing the Steaks

The imagery of cattle on 747, flying 2500 miles across the Pacific ocean took me by surprise –and wasn’t an idea I ever thought I would have to entertain until I began exploring the market potential for pongamia seed cake as a cattle protein supplement in Hawaii.

content cattle

Through this pursuit, I discovered that approximately 75 percent of the cattle raised in Hawaii are shipped, by either plane or boat (via “cowtainers” or “floating feedyards”), for finishing and processing on the mainland. This practice began taking place after a large-scale processing plant closed down in 1990, causing the only large capacity feedlot to follow suit.  In another article, I explain that this practice not only decreases Hawaii’s market share of the industry from 30 percent to less than 10 percent, but also bears down on the islands’ food security and self-sufficiency — a looming issue for Hawaii. Nonetheless, it turns out, shipping cattle live to the mainland for finishing and processing is more economical for ranchers than purchasing feed to finish them here. A big issue is that the cost of feed (protein) is nearly double the price paid by ranchers on the mainland. Thus, with limited local feed options, in addition to veterinary care, branding, processing, and grading services, finishing and marketing the product on the mainland becomes more profitable.

cow calf operations

Cattle production chart depicts each phase of production and relative nutrients. Cow-Calf phase in yellow is what primarily takes place in Hawaii.

The scenario described is exactly why local feed solutions are currently in vogue in Hawaii.  In fact, a variety of industry stakeholders are interested in locally produced livestock feed, especially those derived from biofuel co-products, in effort to bolster Hawaii’s food-security and self-sufficiency, as well as the economic pay-off. With this considered, Pongamia is not only high-performing biofuel but also a potential solution to a eminent food security issue here in Hawaii.

Knowing all this, the seemingly manifest subject-matter of cattle supplementation in Hawaii quickly became a quandary through the market research process. First, Hawaii’s cattle inventory (including calves) is 135,000 head. With only one 950 head capacity feedlot in Maui, most of the weaned calves that are finished in Hawaii (a little over 8,000 head) are almost entirely forage-finished. These cattle are locally marketed as “grass-fed,” which doesn’t necessarily mean that can’t be given supplements but it is indeed a murky market to evaluate. However, most of Hawaii’s beef cattle industry consist of cow-calf operations, which takes place over a year before the finishing (feedlot) phase, as illustrated in the chart below. This is key as supplementation is the most critical during the cow-calf phase, given the mother cow’s high nutritional needs during pregnancy and lactation. With approximately 80,000 mother cows requiring 2-3 lbs of protein a day, this particular market could range from about 2,500 tons of pongamia potential, if only half of the mother cows received the supplement for 365 days, up to 8,000 tons of pongamia potential if all 80,000 mother cows receive the supplement for 365 days.

hawaii climateFor an even more critical look, a majority (about 80 percent) of the cow-calf operations are on the Big Island, where you’ll find one of the most productive (and jaw dropping picturesque) grazing lands in the U.S. Moreover, what you might find surprising, is that the Big Island is home to three of the top 25 largest cow-calf operations namely, Parker (#9) , Ponoholo (#21), and Kahua Ranch (#23). These three ranches (all neighbors – pictured below) make up a quarter of Hawaii’s protein supplement market. Parker ranch alone has approximately 10,000 mother cows over 130,000 acres, in 4-5 climate zones that can be observed from a pu’u (mound) from just up the ranch headquarters. These microclimates, along with the mountainous topography and multifarious winds are certainly factors these ranches take into consideration when choosing to supplement. Parker Ranch, for instance, finds it important to look at the season and time of year, as the nutrients in the forage is dependent on this.parker ranch Ponoholo, on the other hand, over 11,000 acres and three climate zones, prides itself on being a low-cost ranch, that is able to practice intensive rotational grazing which maximizes nutritional opportunities for the cattle, thereby reducing damage to the land through erosion and overgrazing. Given this, Ponoholo would likely forgo protein supplementation even in the event of drought, where they find it best to simply reduce their herd size. Right next to Ponoholo, Kahua Ranch would, however, consider using a protein supplement especially during drought to maintain cow-herd numbers. This illustrates the complexity and case-by-case nature of the cattle protein supplement market Hawaii. Nonetheless, even the ranches that rarely supplement their cattle, are still behind the idea using of pongamia seed cake as a protein supplement — especially in a drought situation, which one rancher explained could be the difference between life or death for a cattle herd.
