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 the present study a deterministic bio-economic model was used to estimate economic values for reproduction traits (conception rate, twining rate and litter size), production traits (body weight of kid sold at 6.5 months, annual cashmere weight, body weight of doe and annual milk yield) and longevity (survival of doe, survival of kid until weaning and survival of kid until sale age at 6.5 mon...
This experiment was conducted to study the effect of different levels of levamisole on performance and related parameters with immune system in Cobb 500 strain male broilers. The experiment was carried out a completely randomized design, with 300 male broiler chickens in four treatments and five replicates 15 birds/replicates. The experimental groups consisted of zero, 2.5, 5 and 7.5 mg pe...
Data analysis in goat production, such as those related to body and scrotal measurements, indicate the productive reproductive animal development. The current study aimed evaluate correlations between thoracic perimeter (TP), length (BL), compacity (BC), volume (BV), circumference (SC) with weight (BW) young male goats of Saanen Boer breeds. It was used 38 24 goats, age average 7.2 ± 2.0 months...
