Pengaruh Waktu Dimulainya Pendinginan Selama Penetasan Terhadap Daya Tetas Telur Itik Persilangan Cihateup Alabio
Abstract: Duck eggs have lower
hatchability because they have higher risk of embryo mortality due to a longer
incubation than chicken eggs. This study was designed to obtain the proper of
start cooling during artificial incubation to improve duck eggs hatchability
and hatching weight. Eggs of cihateup alabio duck were obtained from Balai
Penelitian Ternak (Balitnak) Ciawi. Eggs were collected weekly in 5 different
times. Total egg collected was 419 eggs. Incubated eggs were sprayed and cooled
for 0.25 h at room temperature for 2 times a day in setter period. This study
used randomized block design and 3 treatments of starting cooling time of egg.
Observed variables were egg weight, fertility, hatchability, embryo mortality
and hatching weight. Cooling eggs at different times during the setter period
did not affect to hatchability. Highest hatchability was obtained on Days 17.
The start cooling significantly was affected the hatching weight.
