Abstract: RESUMOO experimento foi realizado com o objetivo de avaliar os efeitos dos níveis de metionina + cistina da dieta sobre o desempenho, características de carcaça e a resposta imunológica de leitões recém-desmamados. Foram utilizados 360 leitões, 180 machos e 180 fêmeas, desmamados com idade média de 18,8 dias e peso inicial de 5,43 ± 1,17kg. Foi utilizado o delineamento de blocos ao acaso em esquema fatorial 5x2, com cinco níveis de metionina + cistina total (0,70; 0,77; 0,85; 0,93 e 1,01%) e duas formas de ati… Show more

“…In our experiment, an extra 0.10-0.15% Met was the best level for FGR in nursery and grower pigs. Supplementation with extra 0.02-0.12% Met has been reported to improve FGR in postweaning and growing pigs (Opapeju et al, 2012;Chen et al, 2014;de Oliveira et al, 2015). This could be explained by met being a functional AA for intestinal growth and function, beyond its role as a precursor for protein synthesis (Wu et al, 2013).…”

“…A higher Met level could represent extra benefits in terms of productive performance. Methionine supplementation (0.02, 0.04, and 0.06%) in growing pig diets has resulted in improved daily gain, feed intake (Opapeju et al, 2012), and feed: gain ratio (Opapeju et al, 2012;de Oliveira et al, 2015). On the contrary, a Met deficiency in pigs can lead to lower DWG (Conde-Aguilera et al, 2014), growth suppression of the intestinal mucosa, reduction of intestinal epithelium, and increase of oxidative stress (Bauchart-Thevret et al, 2009;Chen et al, 2014).…”
