Abstract:
The present study aimed to investigate the effect of reduced dietary crude protein (CP) and supplementation of threonine on the cumulative body weight (BW) and survivability of commercial broilers. A total of 480 broiler chicks randomly assigned to 4 dietary treatments following completely randomized design, each treatment had six replications of 20 birds each. The control dietary formulation was prepared to meet requirement of nutrients and amino acids as per the NRC (1994) [17]. The dietary CP was reduced by 1, 2 and 3 percent unit to standard recommendation in other 3 treatments, the treatments with reduced CP level were supplied with synthetic threonine to need desired level of threonine as in control and all amino acids were met as per the NRC (1994) [17] by supplying the limiting amino acids. From overall study it was indicated that reduction of CP at 1percent unit with supplementation of L– threonine was not affected body weight gain rather helped in gaining similar BW as in control diet but further reduction of CP at 2 and 3 percent unit in the diets significantly reduced body weight gain compare to control diet. The survivability % was similar among the different treatments ranging from 97.50% to 98.33% during the experimental period from 1 to 42 days.
