Utilization of peanut meal in feed and its impact on livestock and poultry production and breeding economic benefits.

Peanut meal is a by-product of peanut oil extraction. It is rich in protein, soluble polysaccharides, vitamins, and other conventional nutrients, as well as a variety of functional factors, including flavonoids, antioxidant peptides, tannins, phenols, steroids, and triterpenoids. Peanut meal can be used directly as feed, and it can be processed through microbial fermentation and microbial enzyme synergistic treatment to improve the quality of peanut meal. Fermentation can make the proportion of amino acids in peanut meal more balanced, reduce or eliminate aflatoxin B1 and antinutritional factors in peanut meal. The direct substitution of peanut meal and fermentation products for part of soybean meal and fish meal in livestock and poultry feed can not only realize the reuse of peanut meal resources, but also improve the production performance of livestock and poultry, increase the economic benefits of livestock and poultry farms. Therefore, the paper introduces the nutritional composition of peanut meal, discusses its utilization in feed, its application in animal production, and its impact on the economic benefits of livestock and poultry breeding, so as to provide reference for the efficient utilization of peanut meal in the livestock and poultry breeding industry.
