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 کاملCarcass and commercial cuts yield in broilers of different ages fed diets supplemented with probiotics
In this study, the carcass and commercial cuts weights and yields in broilers of different ages fed diets supplemented with probiotics were determined. A total of 336 male broiler chicks (Ross-308) were randomly allocated into three treatment groups (P0, P1 and P2). A basal diet (P0), basal diet plus 0.01% (P1) and 0.02% (P2) probiotic (Saccharomyces cerevisiae, 4x10 8 cfu g -1 ) were offered t...
متن کاملEnergy utilisation and growth performance of chicken fed diets containing graded levels of supplementary bacterial phytase.
A total of 364 female Ross 308 chicks (1 d old) were used in the present study conducted in floor pens to investigate the effects of graded levels of supplementary bacterial phytase on dietary energy utilisation and growth performance. For this purpose, four maize-soyabean-based diets were offered to the birds from 0 to 21 d of age. These included a suboptimal P negative control (NC, 3.0 g/kg n...
متن کاملEffect of phytase supplementation on performance of broilers chickens fed diets with graded levels of phosphorus and calcium
One possibility to measure the extra-phosphoric effect of exogenous phytase is to use a higher concentration of this enzyme in the diets not limiting in phosphorus, to be sure that any observed effect is not caused by an increase in phosphorus digestibility. However, it is important to know how the requirements of the bird relate to the phosphorus content of the basal diet, because when the bas...
متن کاملStarch digestibility, energy utilization, and growth performance of broilers fed corn-soybean basal diets supplemented with enzymes.
A study was conducted to evaluate the effects of dietary α-amylase and β-xylanase supplementation of corn-soy diets, formulated with or without supplemental phytase, on growth performance, energy utilization, and starch digestibility in broiler chickens. A total of 336 slow-feathering, Cobb × Cobb 500 male broilers were randomly distributed to 6 treatments having 8 replicates of 7 birds each. B...
