Growth Performance, Carcass yield and Intestinal Microflora Populations of Broilers Fed Diets Containing Thepax and Yogurt
The present study aimed at evaluating the effect of the probiotic thepax and yogurt (as probiotic) on the growth response and intestinal microflora results of broiler chickens. Two hundred forty day-old Ross 308 broilers were equally distributed into 12 floor pens and reared for 42 day. The treatments consisted of yogurt (10, 5 and 2.5% during starter, grower and finisher periods in the drinkin...
متن کاملPerformance and Color of Broilers Fed Diets Containing Rhodocyclus gelatinosus Biomass
The objective of this study was to evaluate the effect of different supplementation levels of Rhodocyclus gelatinosus biomass on the performance and pigmentation of broilers. Cobb broilers were raised in pens and were fed a sorghum-based diet until 35 days of age. At the 36th day of age, ninety-six birds were randomly distributed to four treatments consisting of experimental diets with differen...

متن کاملEffects of Mega Doses of Phytase on Growth Performance, Bone Status and Nutrient Excretion of Broilers Fed Diets Containing High Levels of Rice Bran
Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...
متن کاملGrowth Performance, Carcass Characteristics and Intestinal Microflora of Broiler Chickens Fed Diets Containing Carum copticum Essential Oil
We evaluated the effects of dietary Carum copticum essential oil (CCEO) on growth performance, carcass characteristics and intestinal microflora of broiler chickens. A total of 240 Cobb broiler chickens were allocated to five dietary treatments, each with four replicates of 12 birds. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free of antibiotics (Control) and...
