SELEKSI INDUK KAMBING SABURAI BERDASARKAN NILAI MOST PROBABLE PRODUCING ABILITY BOBOT LAHIR DAN BOBOT SAPIH

Abstract

Most Probable Producing Ability (MPPA) estimation based on offsprings performance is very important in goat selection. This research was conducted to select the best Saburai does based on their MPPA using their kid’s birth weight (BW) and weaning weight (WW) performances in the Regional Technical Implementation Unit of Goat Breeding Centers, Gedongtataan Subdistrict, Pesawaran Regency, Lampung Province. This study used a survey method which was conducted in April-June 2019. Twenty-five Saburai does generating 34 kids at first parity and 33 kids at second parity were used in this study. Data of BW and WW were adjusted for male sex, single birth type, and dam age. Repeatability estimate was estimated using interclass correlation methods and these values were used to calculate MPPA values. The result showed that the average of BW at first and second parity was 3.09 ± 0.42 kg and 3.28 ± 0.54 kg, respectively, while the average of WW at first and second parity was 17.20 ± 1.69 kg and 17.36 ± 2.24 kg, respectively. Repeatability estimates of BW and WW were 0.49±0.08 and 0.55 ±0.06, respectively. The average of MPPA value of BW and WW were 3.19 ± 0,27 kg and 17.28 ± 1.23 kg, respectively. There were six Saburai does (B2, B1, C1, A3, D3, and C8) which had MPPA value of both BW and WW higher than the average MPPA value of the population. These six Saburai does should be maintained in the population to improve the genetics of Saburai goat.
