Effect of using Various Combinations of the Plant Meal as a Source of Vegetable Protein in the Diets of Broiler Chickens in the Productive Performance

This study aimed to know the effect of using various combinations of plant meal as a source of vegetable protein in the diets on the productive performance of broilers. A total (150) unsexed broiler chicks (Ross 308) one day old was used in this study. These chicks were randomly distributed to five treatments with 3 replicates each (10 chicks per replicate), The treatments included the use of soybean meal (SBM) as a source of vegetable protein. SBM level in 1st treatment was 24 % in starter diet and 20 % in finisher diet. Its level was 12 % with 12 % of sunflower meal (SFM) in the 2nd treatment in starter diet or 10 % to each of them in finisher diet. Third treatment included 12 % SBM and 12 % sesame meal (SM) of starter diet and 10 % to each of them in finisher diet. Fourth treatment included 12 % from SFM and 12 % SM for starter diet and 10 % to each of them in finisher diet. Fifth treatment contain 8 % from each SBM and SFM and SM for starter diet and 7 % to each of them for finisher diet The results of the statistical analysis of the experiment data showed. Significant superiority ( P less than0.05) in the mean of weight of birds of experimental treatments (T3, T4 and T5) in comparison with those of control group (T1) at age 4 and 6 weeks, where amounted ( 2439.2442, 2448, 2420) g, respectively. Were also a Significant increase ( P less than0.05) in the rates of the weight gain of birds of (T3, T4 and T5) in comparison with the rate of weight gain to the birds of the control treatment (T1) during ( 0 - 6) week that amounted (2400.2403, 2409, 2381) g, respectively. Live body weight and growth rate of birds in (T2) were similar to those of control. Birds of (T2, T3, T4 and T5) were similar to those of control in the rates of feed intake and feed conversion efficiency during different ages. Absence of significant differences in the percentages of mortality in different nutritional groups. Relative weight of chest and thighs of treated birds exceeded those of control group significantly.
