Soybean meal, a key by - product of soybean oil mills, is rich in protein, typically containing about 43% - 48% crude protein. This high - protein content makes it a valuable source of amino acids for animals. However, controlling its palatability is crucial. Some anti - nutritional factors in soybean meal, such as trypsin inhibitors, can affect the taste and digestion of animals. Through proper heat treatment, the activity of these anti - nutritional factors can be reduced, improving the palatability of soybean meal. For example, heating soybean meal at 110 - 120°C for a certain period can effectively inactivate trypsin inhibitors.
In different breeding scenarios, the proportion of soybean meal in feed varies. In poultry farming, soybean meal usually accounts for 20% - 30% of the total feed. Poultry has relatively high requirements for protein quality, and the balanced amino acid composition in soybean meal can meet their growth needs. In pig farming, the proportion can reach 15% - 25%. For aquaculture, the use of soybean meal also needs to be adjusted according to the type of fish. For example, in carp feed, soybean meal can account for 10% - 20%. Adjusting the proportion of soybean meal according to different breeding scenarios can not only ensure the nutritional needs of animals but also control feed costs.
Globally, the United States, Brazil, and Argentina are major soybean - producing countries, and their soybean production directly affects the supply of soybean meal. In recent years, the global demand for soybean meal has been increasing steadily, mainly driven by the growth of the livestock and poultry industry. In China, the demand for soybean meal is also huge. With the continuous expansion of the scale of livestock and poultry farming, the annual consumption of soybean meal in China has exceeded 70 million tons. Price fluctuations of soybean meal are affected by multiple factors, such as soybean production, international trade policies, and exchange rates. For example, when there is a drought in major soybean - producing areas, the supply of soybean meal will decrease, leading to a rise in prices.
The deep - processing of soybean meal is moving towards high - value - added directions. Functional modification technologies, such as enzymatic hydrolysis, can break down soybean meal proteins into small peptides and amino acids, improving their digestibility and bioavailability. For example, through enzymatic hydrolysis, the digestibility of soybean meal protein can be increased from about 80% to over 90%. Bioactive component extraction technology can extract isoflavones, saponins, and other bioactive substances from soybean meal, which have antioxidant, immune - enhancing, and other functions. These substances can be used in high - end feed products.
In Southeast Asia, due to the rapid development of the aquaculture industry, the demand for high - quality soybean meal is increasing. For example, Vietnam's annual import of soybean meal has been increasing at a rate of about 10% in recent years. In the Middle East, with the improvement of people's living standards, the demand for meat and dairy products is rising, driving the demand for high - quality feed and soybean meal. The export potential of soybean meal to these regions is huge. High - quality, deep - processed soybean meal products can meet the needs of these markets and gain a competitive edge.
To transform soybean meal from a by - product into a high - value product, soybean oil producers and feed enterprises need to invest in R & D and technology upgrading. They should focus on deep - processing technologies, such as functional modification and bioactive component extraction, to improve the added value of soybean meal. At the same time, they need to strengthen market research, understand international market demand, and develop products that meet market needs. By doing so, they can achieve efficient resource utilization and profit growth.
As the famous agricultural research institution XYZ pointed out, "The development of high - value soybean meal products is an inevitable trend in the future of the feed industry."
