Abstract
Effects of low protein diets with amino acids supplementation on biochemical and faeces parameters in weaned piglets
Highlights
IntroductionThe high inclusion of dietary protein and the imbalance of amino acid (AA) composition in animal husbandry result in inefficient utilization of protein resources and increased nitrogen excretion
Dietary protein is the fundamental source of amino acids for pigs
Threonine is considered an essential amino acid and is commonly the second or third limiting AA in pig diets based on corn and soybean meal; it may be the first limiting AA when diets are supplemented with synthetic lysine (Saldana et al, 1994).Threonine is critical for maintenance because it is used for the synthesis of muscle protein, mucin in the gastrointestinal system, and immunoglobulins (Nichols and Bertolo, 2008)
Summary
The high inclusion of dietary protein and the imbalance of amino acid (AA) composition in animal husbandry result in inefficient utilization of protein resources and increased nitrogen excretion. An efficient approach to alleviate the nitrogen excretion and increase the utilization of protein resources is to formulate the AA-balance protein-restricted diet with crystalline AA supplementation (Kim, Chen and Parnsen, 2019). A reduction of dietary crude protein (CP) could limit the growth performance of growing pigs, but a low-protein diet, supplemented with deficient amino acids, could reduce the excretion of nitrogen into the environment without affecting weight gain (Ball et al, 2013; He et al, 2016; Wang et al, 2018). It was concluded that the supplementation of limited amounts of synthetic amino acids to diets for swine could spare 2 to 3 percentage units of dietary protein and substantially
