the present study was conducted to evaluate the effect of vinegar and phytase supplementation on performance, blood lipids, immune system and some carcass characteristics of broiler chickens. for this purpose 240 one-day old male broiler chicks was divided in a 2×2 factorial experiment based on completely randomized design with 4 treatments, 5 replicates and 12 chicks in each and reared through...

The large consumption of biodegradable films from cassava starch acetate (FCSA) as ingredients in food and pharmaceutical products requires the assessment of the possible toxicity of these products. The aim of this study was to investigate the toxicity of biodegradable film from cassava starch acetate after oral exposure of Wistar rats for 90 days. The amount of food consumed and the body weigh...

The purpose of this study was to determine the effects of diabetes mellitus and insulin resistance on semen parameters, histology of reproductive organs and serum concentrations of testosterone and luteinizing hormone (LH). Male Sprague-Dawley rats weighing 180 - 200g were made diabetic by intravenous injection of alloxan (40 mg/kg): and insulin resistant by chronic fructose feeding (25% fructo...

The objective of this experiment was to evaluate the influence of glutamine (Gln) supplementation in the diet of broiler chickens on the growth performance, immune response as well as some blood parameters. Two hundred fifty one day old broiler chickens were allotted into five equal groups (50 chicks per each) of mixed sex. Five experimental diets were formulated to be isonitrogenous and isocal...

This study was organized to examine the effects of use rainwater lost from roofs as water source for broilers on performance and some basic carcass meat quality parameters.
 In research, day old 96 Ross 308 broiler chicks were used. experiment, birds separated two treatment groups given distributed 4 pens under-ground kept in other research house. Performance criteria analyzed with mixed g...

Carcass measurements and some immunocompetence parameters were investigated in naked neck (NaNa & Nana) and normally feathered (nana) genotypes under summer season conditions of Egypt. Two hundred and ten broiler chicks (70 of each genotype) were reared under similar environmental, managerial and hygienic conditions. The feed and water were provided ad libitum. The average high and low ambient ...

A total of 60 male mule ducks and 60 male Muscovy ducks were allotted into three groups (n = 20) to estimate the effects of overfeeding (two and four meals) versus ad libitum feeding on productive performance traits, foie gras production, internal organs, and blood parameters. The results show that force-feeding four meals significantly increased (P < 0.01) body weight, weight gain, and gain pe...
