Effects of Starter Diet Feed Particle and Crumble Size on Performance, Carcass Characteristics and Small Intestinal Histomorphology in Broiler Chicks
This study was conducted to assess the effects of feed particle size (FPZ) and crumble size (CZ) of starter diet on growth performance parameters, carcass characteristics, and small intestinal histomorphology in broiler chicks. Three hundred and sixty male Ross 308 chicks were randomly distributed in a completely randomized design with 3 ´ 2 factorial arrangement consist of three screened FPZs ...
متن کاملBroiler responsiveness (Ross x 708) to diets varying in amino acid density.
Sex-separate male and female broilers (2,592 broilers; Ross x 708) were placed in 144 floor pens (12 replications per treatment) and fed diets containing high (H) and moderate (M) amino acid density from 1 to 55 d of age. Diets were formulated using ileal digestible amino acid ratios to Lys. Six dietary treatment combinations (MMMMM, HMMMM, HHMMM, HHHMM, HHHHM, and HHHHH) were implemented in 5 ...
متن کاملEffect of age on hepatic cytochrome P450 of Ross 708 broiler chickens.
Age has significant impact on hepatic cytochrome P450 (CYP450) systems in animals. Ross 708 broiler chicken is a breed of chicken with fast growth characteristics. Cytochrome P450 in the livers of Ross 708 broiler chicken of different ages has been investigated. The birds were raised under standard husbandry conditions. A certain number of chickens was randomly sampled weekly for liver collecti...
متن کاملTides of the Ross Sea and Ross Ice Shelf cavity
Two new ocean tide models for the Ross Sea including the ocean cavity under the Ross Ice Shelf, are described. The optimum model for predicting ice shelf surface height variability is based on assimilation of gravimetry-derived tidal constituents from the Ross Ice Shelf. Synthetic aperture radar interferograms provide an independent test of model performance. The standard deviation of tide heig...
