Effect of Productivity and Hatchability in Parent Stock Broilers Ross 308 and Arbor Acres Plus S Breeder

Abstract

This study aims to the effect of productivity and hatchability in parent stock broilers, Ross 308 and Arbor Acres Plus S breeder. Using t – test: two – sample assuming equal variances and t – test: two – sample assuming unequal variances experimental plan. There were two factors that were studied. The first factor was the productivity of both breeder parent stock broilers (Ross 308 and Arbor Acres Plus S). The second factor was the hatchability of both breeder parent stock broilers. Breeder chickens are 28-32 weeks old. This experiment was devided 2 groups. Group 1 is the Ross 308 species, with 773 males and 8,144 females tested in the 6^th cage. Group 2 is the Arbor Acres Plus S species, with 773 males and 8,144 females tested in the 8^th cage. The experiment was carried out under raising chickens in an evaporative cooling system which controls the temperature, humidity, light, and ventilation inside the house. As for the incubation of eggs, the hatching system is one-way in and out, which is to bring the eggs into the hatchery on one side. And remove the chicks from the hatchery on the other side without going back. Collecting data on factors affecting productivity and hatching efficiency of parent stock broiler chickens. The results showed that the number of infertile eggs, rejected eggs and dead eggs of the Arbor Acres Plus S was slightly higher than that of Ross 308, which was not statistically different when tested (P>0.05).
