Effect Substitution Partial for Potatoes Peel Powder Raw and Treatment Replaces Maize Yellow in the Performance Productivity for Broiler

Abstract

This experiment was conducted at the poultry \\ Animal Production Department - College of Agricultural Engineering Sciences - University of Baghdad, for the period from 25/2/2021 to me 1/4/2021. To study the effect of substitution partial for powder Peel potatoes raw And the enzymatic treatment replaces maize yellow in broiler diets in Productive performance, used in the experiment 231 chicken (Ross 308) were randomly distributed to Seven treatments by 33 chick/treatment, each treatment contains three replicates, and each replicate contains 11 chicks The experiment parameters were as follows: treatment first T1: treatment control Contains maize yellow 48% and treatment the second T2 and the third T3 and the fourth T4 In which raw potato peels were replaced by 6, 12 and 18%, respectively, as for the fifth treatment T5And the sixth T6And the seventhT7It included the substitution of enzymatically treated potato peels with ratios 6, 12 and 18%, respectively. A mixture of enzymes was used at a rate of 0.5 g/kg of potato peels, the traits under study were recorded over three periods from 1 to 10 days starter diet, 11 to 24 days of a growing diet, and from 25 to 35-day final diet according to the production guide for Ross 308. The data indicated the presence of a high decrease (P<0.01) in treatment T4 And the T7 compared to other parameters of body weight rate, weight gain rate, and feed consumption rate feed conversion factor for different periods.
