Última Growth performance and intestinal health of broilers fed a standard or low-protein diet with the addition of a protease R. Bras. Zootec. Cardinal,Kátia Maria; Moraes,Mariana Lemos de; Andretta,Ines; Schirmann,Graciele Dalise; Belote,Bruna Luiza; Barrios,Miguel Alejandro; Santin,Elizabeth; Ribeiro,Andréa Machado Leal. ABSTRACT We evaluated the effects of a protease supplementation on the growth performance and intestinal health of broilers. Cobb chicks (392; 1-42 d) were divided into four treatments (seven replicates of 14 birds each). There were two feed formulations: a standard diet (SD) and a low crude protein and digestible amino acids diet (Low CP&AA). The two diets were either supplemented (+P) or not (−P) with a protease (Jefo Protease; 1.25 g kg−1). Performance was evaluated by feeding phases (1-7, 8-21, 21-35, and 35-42 d). On day 28, ileum samples were analyzed by a morphometric index for histological alterations (I See Inside Scoring System – ISI). Broilers fed the Low CP&AA had a poor feed conversion ratio (FCR); however, the addition of the protease...

Fischer,Manuela Marques; Moraes,Mariana Lemos de; Marcolla,Camila Schultz; Kessler,Alexandre de Mello. ABSTRACT This study evaluated the nutritional value of glycerin added to diets of weaned piglets and its effects on animal performance and urinary losses. Weaned piglets were individually housed in metabolic cages and fed diets in which a basal diet containing lactose (Gly0) was replaced by 50 (Gly50), 100 (Gly100), or 150 g kg−1 (Gly150) of glycerin; or a diet in which 100 g kg−1 of the lactose in the basal diet was replaced by glycerin (Gly100Lac0). Diets were offered for two periods of 12 days (phase I and phase II). Performance, nutrient digestibility, nitrogen retention (NR), and urinary production were measured. Digestible (DE) and metabolizable energy (ME) of glycerin were calculated using substitution method and compared to iso-nutritional diets...

Bras. Zootec. Cortés,María Esperanza Mayorga; Ribeiro,Andréa Machado Leal; Gianfelici,Mário Federico; Kessler,Alexandre de Mello; Moraes,Mariana Lemos de. An experiment was conducted to define a protocol to determine metabolizable nutrient and energy values of diets. The metabolizability (M) was calculated of the dry matter (DM); crude protein (CP); gross energy (GE) and AMEn of a single diet. Eighty-one 21-day old (d) male birds were used. The tested methodologies were: Cr2O3 (0.5%) as an indicator (partial collection) or Fe2O3 (1%) as a marker; fasting (0, 4, 6 and 8 h) prior to excreta collection and at the end of the feeding period on the last day of collection (total collection). The excreta collection periods were also tested (3 and 5 days). Twenty 31-day old male broilers from the same group of birds were used to assess the effect of fasting on digestive organ weight. At the end of fasting the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chromic oxide; Excreta collection; Fasting; Ferric oxide; Metabolizable energy organ size.
