Abstract: 200 Hubbard broilers were examined to determine the effect of differnet dietary protein levels on the production perofrmance of broilers, at Poultry Experimental Station, Sindh Agriculture University, TandoJam during August-September, 2002. The birds were designated groups A, B, C and D, (fifty chicks each) given 17, 20, 23 and 26 percent protein, respectively. The results revealed that broiler growth and carcass parameters were affected significantly by increasing level of dietary protein. Weight gain in groups A, B, C and D was 1402.40, 1639.63, 1844.90 and 1866.54g against the feed consumption of 3200.00, 3612.28, 3924.78 and 3742.50 g/bird, respectively. Feed Conversion efficiency 2.281, 2.203, 2.127 and 2.005, Carcass percentage 53.88, 59.22, 62.56 and 62.26 percent, Liver weight 39.40, 39.80, 39.60 and 41.20 g, Spleen weight 4.60, 5.00, 6.60 and 6.80g, Heart weight 9.40, 10.40, 11.80 and 12.00g, Gizzard weight 25.90, 30.00, 35.00 and 34.00g, water intake 7469.40, 7771.72, 8263.66 and 8429.50ml. Greater carcass percentage was obtained from ration contained 23% or 26% dietary protein (62.56 and 62.26%). The sale price of the broilers in groups A, B, C and D was Rs. 57.76, 67.24, 75.24 and 76.32 against the production cost of Rs. 54.16, 59.77, 67.24 and 69.59 per bird, respectively. The net profit obtained from groups A, B,C and D were Rs. 3.60, 7.47, 8.24 and 6.73, respectively. Thsi shows that group A (17% CP) or group D (26% CP) were less economical against 23% and 20% CP levels where fairly higher net profit was earned.
