PERBANDINGAN KOEFISIEN HETEROSIS ANTARA KAMBING BOERAWA DAN SABURAI JANTAN PADA BOBOT SAPIH DI KECAMATAN SUMBEREJO KABUPATEN TANGGAMUS
ABSTRACT: Heterosis is the
difference between the average results descent crosses with the average results
of the parent type. Productivity of
Boerawa and Saburai goat can be improved through crossbreeding program to
utilize heterosis effect. Increased
productivity by heterosis occurs due to increased heterozygosity but homozygosity
decline. This research aims to: 1) know weaning weight of male Boerawa and
Saburai goat; 2) comparing the coefficient of heterosis between male Boerawa
and Saburai goat on weaning weight. This
research was conducted on 12th August—13th September 2015 at the farmer group
of Pelita Karya 3, Mitra Usaha, and Handayani in Sumberejo District, Tanggamus
regency. This research used survey method.
The sampling is done by using purposive sampling. The number of samples each 30 individuals
male Boerawa and Saburai. The data
obtained by the secondary data from recording data belongs to a group of
farmers that include the name of farmer group, breeder, goat breed, age of the
parent during childbirth, birth weight, type of birth, sex, weaning age, and
weaning weight.Data were analyzed using student’s t-test on the significantly
level 5% or 1%. The results of this research are : (1) the average of birth weight, weaning weight,
and weaning weight adjusted of male Boerawa are 3.02±0.20 kg, 16.77±0.51 kg,
and 20.82±0.71 kg and male Saburai goat are 3.36±0.31 kg, 17.86±0.79 kg, and
21.45±0.55 kg. (2) heterosis coefficient
of male Boerawa and Saburai goat highly significant (P˂0,01). The average of heterosis coefficient Saburai
goat (2.35±1.55) is lower than Boerawa goat (6.19±1.98).
