ABSTRACT
This study aim is to know the growth curve and the heterosis effect of egg weight, Day Old Chicken weight, fertility, and hatchability from crossbreeding of Sentul Debu and Sentul Kulawu in Poultry Breeding Jatiwangi. The layer period was examined using a sample of 319 chickens selected from two different groups. The first group consisted of 13 males and 147 females Sentul Debu chicken aged 11 months, while the second group consisted of 13 males and 146 females Sentul Kulawu chicken aged 14 months. The hatching eggs produced from breeding one line and crossbreeding were hatched for 21 days, resulting in fertility, and hatchability was calculated as a value of the heterosis effect. Each DOC was identified by wing tagging as identification in body weight at 1-12 weeks. These data are needed to calculate the heterosis effect and measure the growth curve to estimate body weight using the Logistic model. The study showed that the Sentul Kulawu male line of Sentul chickens had the highest body weight of 931.58 grams at 12 weeks of age. In contrast, the crossbreeding between Sentul Kulawu males and Sentul Debu females, produced by Sentul males, had the highest body weight of 973.62 grams at the same age. The research methodology used to measure the heterosis effect involved comparing the average parent with the average crossbreeding in terms of egg weight, DOC weight, fertility, and hatchability parameters. The results indicated that the crossbreeding between Sentul Debu and Sentul Kulawu chicken lines had a negative heterosis effect value for egg weight, DOC weight, and fertility, but a positive heterosis effect for hatchability.
