Sunflower 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 کاملDigestible 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 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...
متن کاملEffects of dietary supplementation of organic acids and phytase on performance and intestinal histomorphology of broilers
The present experiment was conducted to evaluate the effects of organic acids and phytase enzyme supplementation on performance and intestinal histomorphology of broilers. The experiment was done in a factorial arrangement 2 × 2 × 2 based on completely randomized design with eight treatments, five replicates with 12 chicks in each until 42 days of age. Diets included natural vinegar (0 and 2%),...
