| ABSTRACT The effect of egg powder inclusion in the pre-starter diet (1-7 days of age) on the performance, and intestinal morphology and microbiology of male broiler chickens was evaluated in a completely randomized design. Starter diets with equal metabolizable energy and crude protein levels were formulated to contain 0, 20, 40, or 60 g egg powder/kg diet. Results showed that body weight, feed intake, feed conversion ratio, and European efficiency index were positively affected (p≤0.05) by egg powder inclusion in the starter diet. Inclusion of 40 g egg powder/kg diet in the starter diet promoted the best performance results. Jejunal villus height and villus to crypt ratio increased (p≤0.05) and intestinal length decreased (p≤0.05) as a result of egg... |

| ABSTRACT An experiment was conducted to determine the effects of the dietary inclusion of different levels of thymoquinone (TQ) of broilers subjected to oxidative stress or not on the antibody titers against Newcastle disease and on the gene expression of interleukine-1 and interferon gamma. A total of 320 one-day-old broilers was randomly assigned to eight treatments with four replicates of 10 birds each, in a 4 × 2 factorial arrangement, consisting of four thymoquinone (TQ) levels (0, 5, 8, or 11 mg/kg body weight) and two levels tert-butyl hydroperoxide (t-BHP) injection (0 or 0.02 mmol/kg of body weight). Blood samples were collected from two birds per replicate to determine antibody titers against Newcastle disease. At the end of experiment, two birds... |

| ABSTRACT This study was conducted to evaluate the effects of coenzyme Q10, L-carnitine and ractopamine supplementation, alone and in combinations, on carcass traits and immune response of broiler chickens. Five hundred and twelve one-day-old Ross 308 male broiler chickens were randomly allocated into eight treatments with four replicates each. A 2×2×2 factorial arrangement was applied, with two levels of coenzyme Q10 (0 and 40 mg/kg), two levels of L-carnitine (0 and 200 mg/kg) and two levels of ractopamine (0 and 10 mg/kg). The birds were reared until day 42 of age under standard conditions. Blood samples were collected at the end of grower and finisher periods from the wing vein. Four birds per group were sacrificed at day 42 of age. Except for carcass... |

| ABSTRACT The objective of the present study was to evaluate the effects of in ovo infusion of probiotic strains (Bacillus subtilis, Enterococcus faecium, and Pediococcus acidilactici ) on jejunal microbial population and mucin gene expression in broiler chicken. In a completely randomized design, 0.5 ml of mediums containing 107 cfu of different probiotic strains, was administered into amniotic fluid of the 480 Cobb fetus (day 18 of incubation), with four treatments, five replicates with twenty four eggs each. For mucin gene expression, samples from the jejunum were taken on day 21 of incubation and day 3 post-hatch. Microbial profile was determined for total lactobacillus and E. coli by sampling jejunal contents on days 1 and 3 of age. Expression of the... |
