Two concurrent assays were conducted with the objective of evaluating bioequivalence and determining relative bioavailability value (RBV) L-tryptophan biomass 60% for laying hens. In both assays, 98% was used as reference source. A total 216 hens in two assays. The first assay performed using direct comparison method to assess between sources. second assay, slope ratio determine RBV. variables analyzed feed intake, tryptophan egg production, weight, daily mass, conversion ratio, efficiency,...
The objective of this study was to evaluate the performance, carcass yield and growth curves different commercial strains broiler chicken. 2400 day-old chicks, males females Cobb500, RossAp95, Hubbard Flex a new Francesa line were used. birds distributed in completely randomized design factorial arrangement 4x2 (line x sex), forming eight treatments with 10 replicates each. fed same diet. Feed intake, weight gain feed conversion determined. At 42 days, it determined at request cuts each...
1. Broiler breeders are subjected to qualitative or quantitative feed restrictions prevent obesity, which causes major health and welfare problems. Diluting their by adding inert low nutrient, bulky materials can reduce but the capacity of gut needs be determined apply this strategy successfully. Two trials were conducted measure bulk Ross 308 broiler prior after onset lay. The trial was completely randomised, with nine individually-caged breeders, each cage as a replicate, totalling 189...
