ABSTRACT A meta-analysis was employed to assess the effects of phytogenic feed additives and antibiotics on the performance and intestinal morphometry of unchallenged weanling pigs. The database included 41 articles published between 2004 and 2017, comprising 5,197 unchallenged nursery piglets. Piglets had 7.7 to 13.8 kg body weight and were assessed at 27.3 to 47.8 days of age, distributed into 156 experimental groups. All treatments were categorized into negative control, phytogenic additive (PA), and antibiotics (ATB) groups. The meta-analysis followed […]

ABSTRACT The objective of this study was to evaluate the cholecalciferol and 1,25-dihydroxycholecalciferol glycoside supplementation in piglet diet on organ biometry and physicochemical composition, pH of the digestive tract contents, and bone traits. A total of 128 entire male piglets (21 days-old, 6.82±0.38 kg body weight) were distributed in a completely randomized block design with eight replications and four animals per experimental unit. The treatments were composed of a diet 100/0 = 100% of the vitamin D supplemented with cholecalciferol; […]
