Abstract

This study aims to determine the hatching performance of Kokok Balenggek chicken (KBC) using different males as the formation of superior local meat-type chickens. The study used an experimental method, randomized block design (RBD), with eight treatments and three groups. The treatment was male KBC (G0) and the group was the hatching period. Chickens are mated using Artificial Insemination (AI) with a sex ratio of 1:5. A total of 594 KBC egg were selected. The variables of this study consisted of fertility rate (FR%), embryonic mortality (EM%), hatchability of fertile egg (HRF%), and day-old chick (DOC) viability. Data were analyzed using Minitab version 19. The results of the study showed that individual differences in males had non-significant (P>0.05) effect on FR, EM, HRF and DOC viability. The average FR was (73.38%), EM (30.96%), HRF (69.04%) and DOC viability (90.73%). The macroscopic examination of KBC-G0 semen indicated volume as 0.31±0.11mL, consistency to be thick creamy with a milky white color and pH as 7.35±0.17. The microscopic examination of KBC-G0 semen indicated average ++ mass movement and sperm motility, viability and abnormality of spermatozoa to be 71.25±8.35, 78.34±6.22 and 11.67±2.90%, respectively whereas concentration of spermatozoa was 210.46±43.68 x 107 sperm/mL spermatozoa. In conclusion, the eight males KBC have the same and good hatching performance so can be used as males to produce KBC (G1) in the formation of superior local meat type chickens.
