ABSTRACT This study aimed to evaluate the effects of thermal processing and different carbohydrate sources on performance, development of digestive organs, and pancreatic enzyme activity in broiler chicks during the pre-starter phase. The experiment was conducted in a completely randomized design with a 2 × 2 factorial arrangement (pelleting or extrusion processing, and corn or sorghum) and included six replicates of 15 chicks each. The experimental diets were provided only during the pre-starter period (1–7 d). From 8 to 21 […]

The objective of this study was to evaluate the effect of diets supplemented with plasma and/or yeast extract on performance (daily weight gain [DWG], daily feed intake [DFI] and feed conversion [FC]) and intestinal morphology of piglets from 7 to 63 days of age. A total of 288 piglets aged 7 days and weighing 2.57±0.05 kg were studied. A randomized block design consisting of four experimental diets, six repetitions and 12 piglets per experimental unit was adopted. The pre-starter I […]

It was evaluated the effects of using milk protein or supplemental zinc in the diet on performance, relative weights of small intestine and liver, intestine morphology and IGF-I (insulin-like growth factor) serum concentrations, growth hormone and zinc in piglets. The experiment lasted 14 days and it was carried out using 60 piglets weaned at 21 days of age (5.43 ± 0.46 kg) in a complete random design, in a 2 x 2 factorial composed of two levels of milk protein […]
