Web Summary
Soybean meal is the primary plant protein used in most animal feeds, including aquaculture feeds. Heat-treated soybeans, soybean meal, lecithin, crude soybean oil and isolates and concentrates of soybean protein are other soybean products that are used by the feed industry. The nutritive properties of various soybean products are well documented. A product that has recently been developed for application in both human and animal nutrition is soy peptides. This product offers several advantages as an ingredient in aquaculture diets, particularly in shrimp feeds. It serves as an excellent source of small-chain protein molecules that are easily absorbed in the animal’s gut system. The presence of various free amino acids makes it as a potential source of attractants. Its physical form provides good binding characteristics in pellet processing. Its emulsification properties, besides serving a nutritional purpose, may also protect water soluble nutrients in the feed from leaching out into the water.
