Hatching performances of native chicken supplemented L-arginine in ration and in Ovo injection.

This study aims to determine the effect of supplemented by L-Arginine in ration and Treated by L-Arginine in-ovo injection on the hatching performance of native chickens. This study used 60 fertile eggs obtained from hens supplemented by 0% L-Arginine in ration and 60 fertile eggs obtained from hens supplemented by 0.25% L-Arginine in ration. Eggs are arranged by Randomized Block Design with 4 treatments and 3 groups. The treatment consists of P0 (Control=Ration+0% L-Arginine and no L-Arginine injection), P1 (Ration+0% L-Arginine and 2% L-Arginine injection), P2 (Ration+0.25% and without L-Arginine injection), and P3 (Ration+0.25% and injection 2% L-Arginine). The results showed that supplemented by L-Arginine in ration and Treated by L-Arginine in-ovo injection no significant (P>0.05) on the hatching performance of native chickens. We conclude that supplemented by L-Arginine in ration and Treated by L-Arginine in-ovo injection no significant on hatching performance of native chickens although there is a tendency that supplemented of the L-Arginine in ration and Treated by L-Arginine in-ovo injection shows a better trend.
