How Soy Protein Is Helpful in Meeting Animal Fodder Requirements 

Because of the continuing contributions of domestic animals to the global food supply, animal feeds have become an increasingly significant part of the worldwide food supply’s integrated supply chain. 

Livestock products supply 34% of the protein and 16% of the energy used by humans. That accounts for around 30% of the global value of agriculture and 19% of the food production value. A regular supply of suitable, cost-effective, and safe animal feed is crucial to meeting the demand for more meat, milk, eggs, and other livestock products. However, protein availability in livestock feeds has gotten as much attention as it deserves in recent years. 

Many developing nations are making concerted efforts to employ more varied local sources of feed ingredients, particularly protein materials (e.g., India). Soybean meal and fishmeal are increasingly important to chicken operations in other countries (such as Thailand).  

In this article, we will discuss how soy protein helps meet animal fodder requirements: 

 

  • Soya Makes Nutritious Dairy Cattle Feeds

Soy carries a large number of carbohydrates and proteins. In particular, heat-treated soybeans are a good source of rumen undegradable protein (RUP) and fat. Unheated soybeans are a good source of soluble and biodegradable protein. Dairy cattle are fed soybean oil meals to increase their protein intake. A few products made with soybean meal subjected to heat can contribute extra RUP to the diet. The hulls of soybeans can be used as a high-quality fiber food. Their use in dairy cattle diets can increase fodder utilization and reduce the likelihood of rumen acidity. 

Dairy cattle can benefit from adding soybeans and their byproducts to their diets. But like any feed, there are constraints to be aware of if you want to reap the most benefits for your dairy cow. The amino acid composition of U.S. Soy and versatile soy products meal is ideal for increasing digestibility in diets for pigs and chickens. Soybean meal’s amino acid digestibility is crucial for meeting the dietary needs of the animals it feeds to. Soybean meal’s worth can’t be gauged solely by its crude protein content. To ensure the animal gets the protein it needs for tissue formation and other vital metabolic processes, it’s essential to consider the soybean meal’s protein concentration in light of the animal’s digestibility. Soybean meal’s amino acid availability is better quantified by its Standardized Ileal Digestibility (SID) than by its crude protein content.
 

  • Soy Possess Unique Qualities 

 

Argentina, Brazil, and the United States are the three largest exporters of soybeans and soybean meal worldwide, which is used widely in swine and poultry nutrition. Overall, the value of soybeans and soybean meal is based on several intrinsic meal qualities that do differ by origin. Instead of just trying to find the cheapest ingredients, shoppers should consider how those ingredients’ nutritional profiles affect the end diet’s value and performance. It is essential to take a comprehensive approach when examining key quality factors, such as those in the following categories, when assessing the nutritional package that soybean meal delivers in diets. 

 

Whole Soybean Quality 

 

Comparatively speaking, the overall soybean crop in the United States has suffered significantly less damage than in Brazil. Soybean export samples from Brazil were found to have four to six times as much damage as those from the United States. Also, in 2021, the overall moisture content of Brazilian whole soybeans was 12 percentage points greater than that of entire American soybeans. Soybeans that have been damaged less frequently produce a higher-grade soybean meal, and soybeans that have been dried more thoroughly produce a more concentrated nutrient mixture, both highly prized in feed ingredients. 

 

Energy

Soybean meal is commonly used in pig and poultry diets, but its inclusion requires careful evaluation of its energy content and other nutritional qualities. Energy is the most expensive part of a diet, and ignoring the energy content of soybean meals can be costly. Net Energy (N.E.) and Apparent Metabolizable Energy, nitrogen corrected (AMEn) values for U.S. soybean meal are higher than those of Brazil and Argentina, the other two origins evaluated. Energy content is often measured in N.E. for pig diets and AMEn for chicken diets. An increase in vitality is another benefit of sugar. Sugar content in U.S. soybean meal has typically been more significant than in Brazilian meal and on par with an Argentinean meal. U.S. soybean meal has an advantage due to its increased energy and sucrose content, which helps lower the cost of animal diets and improves their productivity. 

 

  • Proteins or Digestible Amino Acids 

 

The amino acid (A.A.) profile and digestibility of soybean meal determine its nutritional value. Soybean meal intake will be modified as a result. Soybean meal’s actual worth may be understated if its digestibility isn’t taken into account, which could lead to over- or underfeeding if it’s not taken into account when creating diets. The A.A. digestibility of U.S. soybean meal for swine and poultry is higher than that of Argentina and Brazil. Better animal performance, less nitrogen loss, and cheaper diets result from increased amino acid digestibility. 

 

  • Process Indicators for Soybeans 

 

Soybean meal’s protein content depends on the processing processes and environmental circumstances under which it is produced. The processing indicators are assessed to determine if the soybean meal has been over-processed, under-processed, or is at an optimal level of processing to maximize protein quality. Based on these metrics, processing conditions for soybean meal in the United States are more favorable, leading to a higher-quality final product. The anti-nutritional factor Trypsin Inhibitor Activity (TIA) is primarily to blame for Brazil’s decline in animal productivity. That’s because the Processing Condition Indicator shows steadier processing conditions (PCI). 

It is crucial to consider each category’s potential to provide for nutritional needs and stability across time. When comparing the nutritional value and overall quality of soybean meal from different countries between January 2020 and July 20212, the United States comes out on top, followed by Argentina and Brazil. 

 

Final Thought 

 

Due to its high nutritional value and positive effect on animal performance, soy has a sizable market in the animal feed industry. Despite the availability of corn protein and an expanding supply of synthetic amino acids, soy has been shown to outperform them in numerous studies.
