To study the effects of terbutaline (a beta adrenergic agonist) on performance of broiler chickens, 21 d-old male and female Cobb broiler chicks (n=300) were randomly assigned to one of five dietary treatments containing 0 (control), 5, 10, 15 and 20 mg terbutaline per kg diet. The feed conversion ratio (FCR), feed intake and body weight gain were measuered after 3 weeks. At 42-d age, six males...

In this study, 360 rainbow trout fingerlings with an average body weight of 10.93 ± 0.2 g were divided into 3 group of BV (8, 12 and 16 μg of bee venom powder) and a control group (commercial diet free of honey bee venom) with three respective replicates. After one week adaptation with experimental conditions, the fish were fed with experimental diets for 60 days. Results showed that final leng...
In this research, influence of Revabio enzyme on improving anti-nutritional of wheat bran (high in fiber, non-starch polysaccharides and phytate) were investigated. The total number of 320 commercial male broiler chicks (Ross 308) in a factorial experiment 4×2 with four replications were used. Treatment consists of four levels of wheat bran (0, 10, 15 and 20 percent) and two levels of enzyme (0...
Two hundred eighty days old male broiler chicks(Ross strain) were randomly distributed into seven groups with four replicates (10 birds in each replicate) and were fed diets supplemented with different dietary fat sources.The results indicated that the different dietary treatments did not affect weight gain, feed intake and feed conversion ratio at 21 d (P>0.05). However, addition of dietary fa...
background: given the importance of birth weight and the effects of anthropometric indices and socioeconomic status on it, this study was conducted to assess birth weight and its related factors among infants born in the hospitals of ahwaz jondishapour university. methods: this cross-sectional study was carried out on 269 newly born babies and their mothers in hospitals of ahwaz jondishapour un...
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...
