Abstract:
The Present study was conducted to evaluate the production performance of Giriraja chicks. The experiment was carried out with 160 Giriraja chicks (day old) distributed randomly into eight groups of two replicates and each replicate with ten chicks for the duration of six weeks. The feed additives like probiotics, prebiotics and acidifiers were supplemented with different combinations through water to improve the performance and livability of Giriraja chicks. The cumulative body weight gains in various treatment varied significantly (P<0.05) from 862.5 g (T-1) to 956 g (T-8). The cumulative feed consumption varied non significantly from 1877.5 g (T-1) to 2002.5 g (T-5). The cumulative feed conversion ratio varies significantly (P<0.05) from 2.06 (T-2) to 2.18 (T-1). The livability percent was 96.7% in T-1 and 100% in all other treatment groups. The net returns per bird between treatment varied significantly (P<0.05) from Rs 51.36 (T-1) to Rs. 63.49 (T-8). Highest body weight gains, feed intake, FCR was noticed in all probiotic supplemented groups. Hence, it is concluded that use of probiotics as feed additive through water or feed can improve overall production performance and livability of Giriraja chicks.
