A study was conducted to compare the effects of iron hydrogen phosphate nanoparticles (FeHPO4) with iron sulfate (FeSO4-7H2O) on growth performance, carcass characteristics and mineral content of breast muscle in broiler chickens. A total of 200 one-day-old male Ross 308 broiler chicks were assigned randomly into four dietary groups with five replications of ten...

this experiment was carried out to evaluate the effect of probiotic supplementation and feed restriction on growth response in broiler chickens. for this purpose, 336 male broiler chickens of ross 308 were used. after housing, broilers allocated to experimental pens in a completely randomized design with factorial 2×3 arrangement. first and second groups considered as positive control group wit...

Feeding trial was conducted in order to study the response of broilers to the different feed additives in combination with one another in order to know which combination of feed additives would give better response. The criteria of response included body weight gain, feed consumption, feed efficiency, cost of feed per kg, body weight gain and mortality. In the experiment Driselase, Biovin-40, N...

Three experiments involving 304 pigs were conducted to determine the related effects of copper (Cu), calcium (Ca) and phosphorus (P) on the performance and liver Cu stores of growing-f'mishing pigs. Rate and efficiency of gain were improved by the addition of 250 ppm of Cu to the diets. Improvements in rate of gain averaged 6.6% (652 vs 696 g/d) to 60.5 kg body weight and 1.7% (713 vs 725 g/d) ...

The aim of the study was to investigate the effects of a standardized mixture of a commercial blend of phytogenic feed additives containing 5% carvacrol, 3% cinnamaldehyde, and 2% capsicum on utilization of dietary energy and performance in broiler chickens. Four experimental diets were offered to the birds from 7 to 21 d of age. These included 2 basal control diets based on either wheat or mai...

A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...

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...
