THE INFLUENCE OF SPINING FREQUENCY ON HATCHABILITY OF VILLAGE CHICKENS EGGS

Abstract

      This study aims to determine the effect of the frequency of spinning on the hatchability of native chicken eggs. The study used a completely randomized design (CRD) with 3 treatments and 6 replications, each with 5 native chicken eggs so that 90 eggs were used. The treatment used was the difference in the frequency of spinning  native chicken eggs during the hatching process: P1 (Spinning 1 time / day), P3 (Spinning 3 times / day) and P6 (Spinning 6 times / day). The variables observed in the study were egg index, hatchability (%), infertile eggs (%), egg shrinkage (weight loss) on day 18, percentage of fertile eggs (%). The results showed that the effect of the frequency of stanning  native chicken eggs on treatment P1, P3, and P6 was not significantly different (P> 0.05) on egg weight, egg index, fertile eggs, infertile and egg shrinkage/ weight loss, but on P3 and P6 treatments had a significant effect  (P <0.05) on egg hatchability. The conclusion of this study was that the frequency of spinning  native chicken eggs 3 and 6 times a day had a higher effect on hatchability than the spinning once a day. The frequency of egg spinning is performed 1, 3 and 6 times a day, does not affect the index of eggs, fertile eggs, infertile eggs, and weight loss of native chicken eggs in the hatching machine.
