This experiment was conducted to assess the effects of using Thyme, Saturea, medicinal plants with or without enzyme on performance, blood parameters in broiler chickens. This experiment was conducted in a completely randomized design with 480 broiler (Ross-308) in 8 treatments and 3 replicates (n=20) for starter (1-21 days) and grower period (21- 42 days). The experimental diets contained: 1, ...
The purpose of this study was to determine the effect giving fermented rice bran in ration on performance male quail aged 2-7 weeks and level could produce average initial body weight, weight gain, final feed consumption FCR ratio. conducted using a completely randomized design (CRD) with 5 treatments 3 replications. Each replication consisted quails so that number used 45. As for treatment as ...
Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg(-1)) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detected betwee...
The aim of this study was to investigate the effect of different levels of soybean meal peptides on body weight gain, feed conversion ratio, feed intake intestinal morphology and microbial population in broiler chicks. In a completely randomized design 280 one-day-old Ross 308 male broiler chicks were allocated to 7 treatments with 4 replicates and 10 chicks per replicate. Broiler c...
in order to investigate the effect of partial replacement of barley starch with beet pulp soluble fiber with or without roasted canola seed on apparent nutrient digestibility, dry matter intake, daily weight gain, feed conversion ratio and rumenal ph 24 arabian male lambs were used for 84 days in a completely randomized design with a 2×2 factorial arrangement. treatments had no significant effe...
non-starch polysaccharides (e.g.: wheat based diet) which are supplemented with enzymes. could have a high potential in nutrient ingestion, digestion and absorption, however, response to the enzyme is dependent on chicks age, as well as genetic status of both the cereal and the chick. this study was conducted in a completely randomized design in 2×4 factorial arrangement to study the efficiency...
The trial was conducted to evaluate the effect of different levels of dried sweet orange (Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only...
the present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under phs with respect to changes in the levels of lipid peroxidation marker malondialdehyde (mda), total antioxidant status (tas) and the activities of anti peroxidative enzymes [superoxide dismutase (sod) and glutathione dependent antioxidant enzymes glutathione peroxidase (gpx)]...
This experiment was conducted to determinate the effects of different levels of Amet protein binder (0, 1.5, 3, 4.5 and 6) in substitution for fish meal on performance and digestibility of nutrients. This study used 400 broiler chickens (Ross strain) with 5 treatments of 4 replications in a completely randomized design. Weight gain, feed consumption, and feed conversion ratio were determined at...
This study evaluated the effect of 2 levels (0 vs. 8%) of distillers dried grains with solubles (DDGS) in a starter broiler diet (0 to 14 d; 45 replicates/treatment) after these same birds were subsequently fed a grower diet (14 to 28 d) with either 0, 7.5, 15, 22.5, or 30% DDGS (9 replicates/treatment). Ross×Ross 308 male broilers were used in this experiment, and evaluation criteria consisted...
