The aim of this study was to determine growth performance, meat quality, and oxidative changes in breast muscles depending on the genotype and age of broiler chickens. The experiment was conducted on 1080 chickens: fast-growing Cobb 500, medium-growing Hubbard JA957, and a slow-growing experimental line. Chickens from all genetic groups were reared on litter for 8 weeks, but from the 5th week of age, 15 chickens from each group were slaughtered every week. After slaughter at weeks 5, 6, 7, and 8 of chickens? lives, their muscles were sampled for chemical composition, fatty acid profile, and cholesterol. Contents of reduced …

This study was conducted to investigate the comparative efficacy of three different concentrations of acetic acid on broiler chickens experimentally challenged with Salmonella enterica serovar Pullorum (S. Pullorum). A total of 360 birds were divided into five groups (A?E). Group A served as the unchallenged, untreated control. All the birds in groups B?E were challenged with 4 × 104 cfu/mL of S. Pullorum. Birds in groups C, D, and E were respectively treated with three different concentrations, 0.5%, 1%, and 1.5%, of acetic acid. Pathological examination revealed congested and hemorrhagic liver, hepatitis and necrotic areas in the liver, hydropericardium, focal …

Piglets were allocated to 1 of 3 treatments by body weight and sex, and fed different levels of 0%, 0.15%, and 0.30% of R. oligosporus 1.0 x 106 cfu/g, in a basal diet based on corn-soybean meal for 35 days. Piglets fed diets supplemented with R. oligosporus had higher average daily gain during days 15-35 and 1-35 (quadratic, P < 0.05). Feed conversion ratio during 1-35 days showed a significant improvement, as dietary R. oligosporus supplementation increased from 0.15% to 0.30% (linear, P < 0.05). Apparent total tract digestibility (ATTD) of crude protein (CP) was increased at 2 weeks, as dietary R. oligosporus supplementation increased significantly (linear and quadratic, P < 0.05), and ATTD of dry matter, CP, and energy were linearly increased at 5 weeks (P < 0.05). The serum IgG concentration was significantly increased in the R. oligosporus-fed groups (quadratic, P < 0.05). Fecal Lactobacillus counts were significantly increased quadratically and coliform bacteria counts were decreased linearly, as dietary R. oligosporus supplementation increased (P < 0.05). In conclusion, diets containing R. oligosporus may improve the growth performance, nutrient digestibility, IgG concentration, and intestinal environment in weanling pigs.
