Abstrakt: Background: Recently, efforts like crossbreeding, strain crossing, and inbred hybridization have been performed to improve productive performance in native chickens. This experiment was carried out to evaluate the effects of crossbreeding on the improvement of the productivity of a native chicken. The White Leghorn exotic chicken (WL) as dam line and the Marandi indigenous chicken (MA) as sire line were used to generate the crossbreds (MA × WL). Body weight and egg production traits were measured in the three groups.
Results: There are significant performance differences between WL and MA, with WL exhibiting superior body weight and egg production compared to MA (P < 0.05). Crossbreeding between WL and MA significantly improved most traits, with MA × WL outperforming MA. Negative heterosis was observed for body weight showing similarities between MA and MA × WL. Notably, MA × WL showed a closer resemblance to WL than MA in hen-day egg production at 40 and 44 weeks (P < 0.05).
Conclusions: The results derived from this study show that the economic performance of native chickens can be enhanced through crossbreeding with exotic chickens. Using the crossbred chickens in rural areas can be more efficient than the native chickens. In addition, the resilience of the native chickens to the local environment can be transmitted genetically to the crossbred which should be investigated in further studies.
