Digestible lysine requirements of male broilers from 1 to 42 days of age reassessed
Three experiments were conducted separately to estimate the digestible Lys (dig. Lys) requirements of Cobb × Cobb 500 male broilers using different statistical models. For each experiment, 1,200 chicks were housed in 48 floor pens in a completely randomized design with 6 treatments and 8 replicates. Broilers were fed diets with increasing dig. Lys levels from 1 to 12 d (Exp. 1), from 12 to 28 d...
متن کاملDigestible lysine requirements of male and female broilers from fourteen to twenty-eight days of age.
There is little research data available on the digestible Lys requirement of broilers from 2 to 4 wk of age. Two experiments were conducted to determine the digestible Lys requirements of male and female Ross x Ross TP16 broilers from 14 to 28 d. Two diets (dilution and summit) consisting of corn, soybean meal, poultry by-product meal, and peanut meal were formulated to be adequate in all other...
متن کاملDietary digestible lysine requirements of male and female broilers from forty-nine to sixty-three days of age.
Experiments were conducted to evaluate digestible (dig) Lys requirements of male and female broiler chickens from 49 to 63 d of age. A dose-response diet consisting of corn, soybean meal, and corn gluten meal was formulated to be adequate in dig amino acid concentrations with the exception of Lys. L-Lysine . HCl was added to the dose-response diet to create 7 experimental diets. Concentrations ...
متن کاملSunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
متن کاملOptimal dArg to dLys ratio of male broilers from 28 to 42 days of age during a constant, elevated temperature
The effects of environmental temperatures on live performance and carcass characteristics of broilers have been well documented [1, 2, 3]. In addition, Cahaner et al. [4] reported that nutritional requirements are affected by variations in ambient temperature. Amino acid requirements and digestibility in broilers and laying hens at high temperatures is known to vary from those that are raised a...
