This study was carried out to evaluate the duration of time of feeding starter and finisher diets on live performance and carcass characteristics of female broilers. Starter diet was fed to 14 or 21 days of age. Finisher diet was fed beginning at 35 or 42 days up to 49 days of age. The results indicated that reduction of duration of feeding starter diet reduced weight gain (P<0.0071) and impair...

The purpose of this research was to evaluate the effect of early life nutrient restriction and subsequent intermittent lighting schedule on performance in broiler. In a factorial experiment, the effect of three levels of feeding regimes and two levels of lighting schedule were investigated using 480 day-old male Hubbard chicks. The broiler chickens were randomly distributed over two rooms consi...

In this study, a feeding trial was conducted to examine the potential of replacing fish meal with brewers yeast in practical diet of goldfish (Carassius auratus). Five isoproteic (37% CP) and isocaloric (3350 kcal/kg) diets were formulated to contain graded levels of brewers yeast. Fish meal protein was replaced by 0%, 15%, 25%, 35%, and 45% of yeast. Each diet was randomly allocated to triplic...

   This study was conducted to compare the feedlot performance and growth traits of Lori-Bakhtiari (n=39), Romanov × Lori-Bakhtiari (n=38) and Pakistani × Lori-Bakhtiari crossbred (n=12) lambs during two consecutive years. Lambs were weaned at the age of 90 ± 5 days. After weaning and preliminary fattening period, three groups of lambs were fattened for 90 days in the same conditions. The resul...

     A 28-week experiment was conducted to study the effects of dietary energy and digestible methionine level on performance and reproductive traits of broiler breeder hens, using 280 Arian broiler breeder hens and 20 males at 26 weeks of age. The experiment was done as 2×2 factorial arrangement in a completely randomized design with 4 treatments and 5 replicates. Dietary treatments were formu...
