PSXI-28 Reducing dietary crude protein and supplementation with amino acids helps mitigate the environmental impacts of growing pigs production determined by the life cycle assessment
Abstract:This study aimed to evaluate, through life cycle assessment and using experimental data, the environmental impacts of growing pigs’ production (30 to 50 kg) fed diets with reduced crude protein (CP) levels, and supplemented with industrial amino acids. Experiment I (nitrogen and phosphorus balance): 20 crossbred barrows, averaging 31.80 ± 2.39 kg of initial body weight, were housed in metabolic cages and allotted in a randomized block design with four treatments, five replicates and one animal per experimental… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
