EFFECT OF REPLACEMENT THE LOCALLY PLANT PROTEIN CONCENTRATE FOR IMPORTED ANIMAL PROTEIN CONCENTRATE ON PRODUCTIVE PERFORMANCE OF BROILERS

This experiment aimed to study the effects of partial and complete replacement of animal protein concentrate by locally produced plant protein concentrate (sunflower meal supplemented with amino acids, vitamines and minerals) on the performance traits of Fawbro (CD) broiler chickens. Five treatments were used included, 1 -control (T0)=100% animal protein concentrate + 0.0% plant protein concentrate, 2-T1= 75% animal protein concentrate + 25% plant protein concentrate, 3- T2 = 50% animal protein concentrat+50% plant protein concentrate, 4-T3= 25% animal protein concentrate + 75% plant protein concentrate and 5-T4= 0.0 % animal protein concentrate+100% plant protein concentrate with similar levels of total protein and energy in all treatments. Data were collected for live body weight, weight gain, feed consumption and feed efficiency from 2-8 weeks of age, and for slaughter weight, dressing percentage, main carcass cuts and the total count of intestinal bacterial content at 8 weeks. Results indicated that no significant differences between treatments in live body weight and weight gain during the first 2-6 weeks of age. However the differences became significant for the live weight at 8 weeks of age and for the weight gain during the period 6-8 weeks, as well as for the accumulative period 2-8 weeks for the above mentioned traits. T4 gave the highest live body weight (2362.6 g/bird)at 8weeks of age. followed by T3 (2338.5 g/bird), however birds in TO showed lowest live body weight (2256.5g/bird) an the lowest weight gain (1968.0 g/bird) in this comparison. Data of feed consumption indicated that no significant differences between treatments during the first 4 weeks of age, but it became significant as the age progress. Birds in T4 consummed more feed (4768.7 g/bird during the period 2-8 weeks), however birds of TO consummed the lowest amount of feed (3963.7 g/ bird) during the same period, therefore TO gave the best feed conversion ratio (2.02 g. feed: g.gain) in this comparison. There were no significant differences in dressing percentage, internal organs weights and main carcass cuts, however significant lower dressed weights were obtained from birds in TO. Significant increase in the total count of intestinal bacterial count and colon bacteria of birds in TO as compared with T3 and T4. No significant difference in mortality rate due to the replacement of plant protein concentrate for the animal protein concentrate. Results of this experiment refer to the possibility of substitution of the imported animal protein concentrate by the locally produced plant protein concentrate in broiler diet.
