Increasing the Egg Weight of Burgo Chicken Offspring through Cross-Mating Between Burgo Chicken with Native Chicken

Abstract

The research was aimed to increse the egg weight of burgo chicken offspring. The research used 300 hens, offspring from four mating types between burgo chicken and native chicken. These offspring were resulted from the succesive four mating groups of: a. Native cock with native hen (KK); b. Native cock with burgo hen (KB); c. Burgo cock with native hen (BK); d. Burgo cock with burgo hen (BB). The offspring in each mating group consisted of three postal coops, and each postal coop was filled by 25 hens. Variables collected from the hen offspring included for egg weight and egg production. Result showed that the egg weights of the cross-mating offspring of burgo chicken with native chicken were higher than those of mating offspring within BB. The increased egg weight of the KB cross-mating offspring was 30.79%, while that for the BK cross-mating offspring was 62.79%. However, the average egg production of the cross-mating offspring within Burgo chicken (BB) was the highest compared to the others (KB, BK, and KK). The egg production of the KB cross-mating offspring decreased 12.95%, while that for the BK cross-mating offspring decreased 19.77%. It can be concluded that the cross-mating offspring of both KB and BK mating types could be sonsidered for the purpose to produce relatively small egg production with the increased egg weight.
