| Abstract | ||||
| The objective of this study was to evaluate the influence addition of papaya latex on productive performance, digestibility, egg qualities, semen quality, carcass traits, immunity, some blood constituents and economic of efficiency of Dokki4 strain. A total number of 132 Dokki4 hens and 12 Dokki4 cocks, 32 weeks of age were randomly distributed into 4 groups with 3 replicates each (11 hens+1cock). Chicks were randomly divided into control (without any addition of PL0) and 3 treatment groups (basal diet containing papaya latex ground powder at levels 0.01(PL1), 0.03 (PL2) and 0.05% (PL3). The obtained results could be summarized as follows: 1) Final body weight, body weight gain, egg production, egg weight and egg mass for the layers fed diet supplemented with PL were increased significantly than those fed control diet. A feed conversion ratio was significantly improved with PL, whereas, daily feed intake significantly (P≤0.05) decreased with PL inclusion. 2) Digestibility coefficient values were significantly improved for hens fed diet supplemented with PL compared to those fed control diet. | ||||
