Research Progress in Processing Techniques for Improving Amino Acids Digestibility of Pig Feed
Amino acids are essential nutrients for pigs and are also one of the rarest and most expensive compo-nents in feed ingredients,playing a decisive role in healthy growth of animals and feed ingredients costs.The anti-nutritional factors,fiber,and protein structure in feed can all affect the digestibility of amino acids,and different processing techniques can eliminate or weaken the effects of these factors to improve the digestibility of amino acids in pigs feed.This article mainly reviews the effects of processing techniques such as grinding,extrusion,pelleting,enzymatic hydrolysis,fermentation,fermented with bacteria and enzyme,and heating on the amino acids digestibility of pig feed.[Chinese Journal of Animal Nutrition,2024,36(4):2091-2103]
