Abstract
The performance of broiler chicks fed plant-protein-diets ( starter, grower, finisher ) was compared to those fed diets supplemented with 5% meat and bone meal, (67% protein). One hundred and sixty, one day old male Ross broilers, were used. A total number of 80 chicks were allocated for each treatment, divided into four replicates of 20 birds each, and housed in broiler cages .The experimental diets were formulated to cover the chick requirements as recommended by the management guide data ( Ross). The protein Efficiency Ratio (PER) of both dietary proteins were almost of the same value. Also the essential amino acid make up (or pattern) of the proteins of both sets of diets contained almost the same concentration and pattern .Body weight gain and efficiency of feed utilization during the three growth periods of chicks fed either plant-protein diets or those fed the animal protein supplemented diets ,were almost of similar magnitude with no significant differences. The final body weight of broilers fed plant-protein diets 'surpassed those of chicks fed the animal protein supplemented diets . While, the over all feed efficiency showed better values with chicks fed the animal protein supplemented diets, with no significant differences compared to those fed plant - protein diets. Abdominal Fat Pads were significantly lower in birds fed plant-protein diets .The cost of feed required to produce 1 kg live weight gain was LE 1.59, for chicks fed plant-protein diets compared to LE 1.56 for those fed animal-protein supplemented diets with a difference of 1.9% on the time of experiment .The results of the present work encouraged CLFF to implement such work on semi commercial production scale. A broiler house of 16000 broiler chicks capacity per run, was used. Four runs were carried out during the period from Jan. up till Nov.2003 and showed that mortality rate was below 5%, average live weight ranged between 1650-1850 g ,with an efficiency of feed utilization ranging between 1.70-1.87 kg feed I kg live weight at 37 days of age (slaughter date) . The quality of birds meat fed plant protein diet is better, less abdominal fat pad, more thickness of breast tender and tasty.
