Phenotypic Study Results of Crosses between Local Chickens with Layer Chicken Isa Brown

Abstract

This research was conducted to produce crossbred by cross between local chickens with laying chicken strain isa brown. This study uses 3 types of local chickens, namely sabu chicken (C1), bangkok chicken (C2), and naked neck chicken (C3) which is crossed with laying hens Isa brown. Phenotypic properties studied include egg production, egg weight, fertility, hatchability, embryo mortality and hatching weight. The results showed that mating group have not significant effect (P>0.05) on egg production as measured by HDP but had significant effect (P<0.05) on egg weight. Mating groups also had no significant effect (P> 0.05) on egg fertility. Hatchability of each mating group from lowest to highest, C3 = 45.75 ± 19.03%, C1 = 49.35 ± 15.34%, and C2 = 58.37 ± 14.17%. However, statistically found there was not significantly different (P> 0.05). Embryo mortality rate was found to be quite high for the three mating groups, i.e C3 = 54.25 ± 19.03%, C1 = 50.65 ± 15.34%, and C2 = 41.63 ± 14.17%.  This study uses Completely Randomized Design with the mating group as the treatment. The treatments are C1: sabu rooster x isa brown hen, C2: bangkok rooster x isa brown hen, and C3: naked neck rooster  x isa brown hen. Each treatment was repeated 3 times and each replication consisted of 5 hens. but not significantly different (P> 0.05). The resulting hatching weight ranged from 43.85 to 46.84 grams with average for each group was C1 = 44,26 ± 4,76 grams, C2 = 46,04 ± 4,59 grams,  and C3 = 43,85 ± 4,30 grams. Statistical analysis showed that mating groups had no significant effect (P> 0,05) on the hatching wight. Cross between bangkok rooster and isa brown hens showed better results compared to the other two crosses.
