six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...
in order to investigate effects of partial replacement of starch with neutral detergent soluble fiber (ndsf) on weekly weight gain, feed intake, feed conversion ratio, digestibility and some histopathological changes of rumen, 16 lambs were used in completely randomized design. the experimental period was 70 days. dietary treatments were 1- control (high starch), 2- beet pulp, 18 percent, 3- be...
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)]...
the objective of the present study was to evaluate the effects of inbreeding on average daily gains and kleiber ratios in moghani sheep. traits included average daily gain from birth to 3 months (adg1), average daily gain from birth to 6 months (adg2), average daily gain from 3 months to 6 months (adg3), average daily gain from 3 months to 9 months (adg4), average daily gain from 3 months to ye...
This study was conducted to investigate the effects of artichoke powder on performance and immune function of Japanese quails poisoned with carbon tetrachloride (CCl4). One hundred meat type (1-d-old) quails were assigned randomly to 4 treatment groups (n=25). Treatment groups included with the study were: 1) control group (without artichoke supplementation or CCl4 administration, 2) group with...
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 between ...
This experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. One hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...
In this study, growth and survival of the Caspian whitefish, Rutilus frisii kutum, (mean weight 0.59±0.06g) have been estimated at different rearing salinities (0, 5 and 10‰) and temperatures (24 and 28˚C). Maximum fish weight gain (493.65±14.07%) and specific growth rate (SGR) (2.74±0.15%), and minimum feed conversion ratio (FCR) (1.66±0.06) were obtained at salinity of 5‰ and temperature of 2...
The present study was performed to investigate the effects of dietary electrolyte balance and probiotic on the performance and carcass characteristics in Japanese quail under heat stress conditions. A total of 672 quail chicks (20-day old) were studied in a three-factor, factorial experiment with 4 replicates and in each replication of 14 birds during 20 to 37 and 20 to 41 days Factors included...
