Pengaruh Frekuesi Pendinginan yang Berbeda Terhadap Daya Tetas Telur Itik Persilangan Cihateup Alabio
Abstract: Increasing of duck
rearing as a meat producer requires an increase in duck population to fulfill
the demand. The objective of this
research was to analyze the proper chilling frequency to increase duck egg
hatchability from cihateup alabio cross breeds.
Chilling frequencies used in this study were once, twice, and three
times. One time chilling was done in the
afternoon (12.00-13.00). Two times
chilling was done in the morning (06.00-07.00) and in the evening
(17.00-18.00). Three times chilling was
done in the morning (06.00-07.00), in the afternoon (12.00-13.00), and in the
evening (17.00-18.00). Materials used in
the research were digital thermometer, 491 eggs from Balitnak Ciawi, KMnO4,
Na2CO3, 40% formalin, and chlorin. The
result showed a high fertility on duck egg from Cihateup Alabio cross breeds
(>75% on average) with 4 : 16 (male : female) sex ratio. All of the chilling frequencies had no
significant effect on egg hatchability from Cihateup Alabio cross breeds.
