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...
To investigate the efficacy of alternatives to antibiotics, the present study was conducted to compare the effects of antibiotic, lactic acid, a blend of commercial essential oils (EOs) and EOs in combination with lactic acid on growth performance and the functional activity of the gut in broiler chickens. A total of 168 broiler chickens were given the basal diet supplemented with 10 ppm colist...
Effect of Constant or Gradual Reducing Light Intensity Ambient on Performance, Carcass Characteristics and Immune Parameters in Broiler Chickens
In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...
in order to evaluate the effect of feeding different levels of vermi-humus supplement (as a source of humic acid) on the performance of broiler chickens an experiment was conducted using 240 broiler chickens (ross 308) in a completely randomized design by four treatments (vermi-humus levels of 0, 0.5, 1 and 1.5 percent) and five replicates of 12 chickens per each for 42 day. the experimental tr...

Investigation of Performance and Comparison Cytochrome P450 Isoforms in Broiler Chickens Liver Fed Silver Nanoparticles Coated on Clinoptilolite
In broiler chickens, feed additives, including prebiotics, are widely used to improve gut health and to stimulate performance. Xylo-oligosaccharides (XOS) are hydrolytic degradation products of arabinoxylans that can be fermented by the gut microbiota. In the current study, we aimed to analyze the prebiotic properties of XOS when added to the broiler diet. Administration of XOS to chickens, in ...
The Effect of using a Combination Phytase and Synbiotic in Phosphorus Deficient Diet on the Performance Blood Parameters Broiler Chickens
The present paper explores amino acid composition of breast and thigh muscles of common pheasant and compares it with that in broiler chickens. The experimental feeding of both pheasant and broiler chickens proceeded for a period of 42 days at the identical conditions employing the same diet and rearing technology. Muscles were analysed for the content of following amino acids: Asp, Thr, Ser, G...
