Pengaruh Taraf Protein Dan Lisin Ransum Terhadap Performans Produksi Ayam Kampung (Effect of Dietary Protein and Lysine Level on the Production Performance of Native Chicken)

This research aimed to examine level of dietary protein and lysine which is optimum for native chicken performance. Parameters measured were feed consumption, body weight gain, feed conversion, carcass percentage, and meat bone ratio. The research used completely randomized design in 2 x 3 factorial pattern with dietary protein level as the first factor and lysine level as the second factor. Each treatment had 4 replications with 10 heads per trial unit. Treatments applied were P1L1 (protein level 17% + lysine addition 0.6% of diet), P1L2 (protein level 17% + lysine addition 0.7% of diet), P1L3 (protein level 17% + lysine addition 0.8% of diet), P2L1 (protein level 14% + lysine addition 0.6% of diet), P2L2 (protein level 14% + lysine addition 0.7% of diet), P2L3 (protein level 14% + lysine addition 0.7% of diet). The treatment was started to be offered from 1-day-old and completed when the chicken were 12-week-old. The data was analyzed using F test to determine the effect of treatment, continued with Duncan's multiple range test at 5% probability level if any significant effect was found. The results showed no effect of the interaction between dietary protein and lysine on feed consumption, body weight gain, feed conversion, carcass percentage, and meat bone ratio. Based on the results, it was concluded that lysine addition was not give significant effect on native chicken performance
