Effect of dried bakery powder with and without yeast in the diet on some productive traits of broilers Ross 308.

This experiment was conducted to find out the effect of replacing two levels dried bakery with and without yeast instead wheat barley on productive performance Ross 308 broilers. At poultry field, for research station, College Agriculture Marshes, Thi Qar University, from 11/8/2020 12/12/2020, using 270 unsexed one-day-old broiler chicks, were randomly distributed over five experimental treatments three replicates (18 birds/replicate). The as follows: T1: control treatment addition, T2 T3 added 10 20% powder yeast, T4 T5 0.04% yeast. results study indicated that there a significant (P≤0.05) improvement in studied traits (Body weight, weight gain, feed intake, food conversion factor, mortality, vital ratio, production index) broilers, when best addition ratio compared yeast.
