This research was conducted to determine the effects of supplementation chitosan oligosaccharide (COS) on growth performance, blood parameters, carcass traits, fatty acid composition breast meat, and apparent nutrient digestibility in broiler chickens. A total 375 one-day-old Ross 308 male chicks were allocated a control diet (T1) or diets supplemented with 50 ppm (T2) 100 (T3) COS. There five ...

The main goal of the current study was to investigate effects feeding low protein (LP) diets on performance parameters and excreta composition broiler chickens. In total, 288 male Ross 308 day-old chickens were divided into two dietary treatment groups using six replicate pens with 24 each. No LP diet fed in starter phase. reduction grower finisher phases 1.8% 2% respectively. Beside measuremen...

a study was carried out to examine the effect of different levels of herbal methionine and dl-methionine on the growth performance and immunocompetence of broiler chickens fed on a corn-soybean meal diet. a total of 225 old male broiler chickens (ross 308) were used as experimental samples in a completely randomized design. they were randomly assigned to 9 treatments each of 5 replicates in eve...

Methods: Ammonia concentrations in farrowing, nursery, finisher, and gestating barns were monitored for 8 weeks using both the pHydrionTM test strips and the DraegerTM unit. The ammonia measurements were compared using bivariate correlation analysis. Average ammonia concentrations in each barn type were compared using an ANOVA. The precision and costeffectiveness of each assay were demonstrated...

An experiment was conducted to determine the efficacy of dietary conjugated linoleic acid (CLA) as a growth promotant in weanling swine. Weanling pigs (n = 192; 7.6 kg and 29 d of age) were randomly assigned to four treatments that were arranged as a 2 x 2 factorial. Concentrations of dietary CLA (0 or 0.6%) and antibiotics (+/-) constituted the main effect variables. Dietary CLA treatments con...
