This study was performed by five treatments and three replicates using 180 Ross male broilers (12 birds in each pen) in a completely randomized design. Feed restriction was applied by supplementing the rice hull levels (0, 15, 30, 45 and 60 percent). To grower feed (7 to 14 days of age). Average feed intake had a linear decrease with increasing in rice hull levels. Body weight was decreased lin...
the aim of this study was to compare the effects of three antibiotic alternatives with a control (antibiotic-free) and an antibiotic diet on performance and gut morphology of broilers reared on litter. 600 day-old ross-308 chicks were assigned to 48 pens in a crd design with 6 × 2 factorial arrangements, in which 2 levels of chick density (5 and 7.5 chicks/m2) and 6 experimental diets (control,...
The growth-promoting effects of two dietary acidifiers based on formic acid were studied with 320 fattening pigs from ca 2 kg to ca 05 kg of body weight. The sorbate-coated formic acid contained formic acid and ammonium formate which were absorbed in diatomaceous earth and coated with potassium sorbate. The investigated liquid blend contained formic and lactic acids as the major components. The...
Introduction & Aim: The aim the present study is to examine the effects of Boswellia serrata Triana & Planch on (immune response) performance and carcass characteristic in broiler chicks. Experimental: In this study, 360 one day old chicks (Ross 308) were allocated to six treatments with four replicates in a completely randomized design for a six week period. Treatments consisted of ...

an experiment was conducted to investigate the effects of different levels of rapeseed meal and diet formulation based on total and digestible amino acid (aa) using 192 day old ross 308 male broiler chicks. experiment was carried out using a complete block design with 4*2 factorial arrangements. the factors included different levels of rapeseed meal (0, 10, 20 and 30%) and two method of aa form...
This study was conducted to evaluate the effects of lavender (Lavandula angustifolia)extract as an alternative to flavophospholipol on performance, carcass characteristics, antioxidant status,meat quality, intestinal morphology and ileal microflora of broilers. A total of 220 day-old male broiler chicks (Ross 308) were used in a completely randomized design with five treatments each re...
Two hundred Arian broiler chicks were used to investigate the effect of contents of dietary glucosinolates on performance of broiler chicks during starter (0-21 days of age) and grower periods (22-42 days of age) in a completely randomized design. The dietary glucosinolates contents in the starter period were 0 (S1), 7.5 (S2), 15 (S3), 22.5 (S4), 30 (S5) µmol/g and in the grower period they wer...
This experiment was conducted to study the effects of using cotton-seed meal on the performance and carcass yield of broiler chickens at different ages. The experiment was performed in a completely randomized design with four treatments and five replicates for each treatment. The experimental treatments included the levels of 0, 3.5, 7, and 10.5% of cotton-seed meal in diets fed to chickens at ...
