The Estimation of Breeding Value of Saburai Goats at Weaning Weight in Gisting Atas Village, Gisting District, Tanggamus Regency, Lampung Province, Indonesia

Abstract

Background and Objective: One of the goats developed in Lampung Province is the Saburai goat. Selection is an action to select livestock with good genetic quality. This study aims to determine the genetic potential of male and female Saburai goats that have good genetic quality at weaning based on their estimated breeding value (EBV) and to determine which individuals are eligible to be retained in the population. Materials and Methods: This research was conducted in March-May 2021 at Gisting Atas Village, Gisting District, Tanggamus Regency. This study used a survey method using primary and secondary data. Primary data was obtained from interview questionnaires and measuring the weaning weight of goats. Secondary data was obtained from weaning weight data in the recording. The observed variables were birth weight, weaning weight, weaning age, age of the dam at partus, type of birth, and sex. Results: The results of this study showed that the average weaning weights of male and female Saburai goats were 16.46±1.1 kg and 16.40±0.98 kg, heritability value was 0.37±0.24 and EBV of weaning weights of male were 16.45±0.40 kg and female Saburai goats 16.39±0.37 kg, respectively. Conclusion: There were 5 males with the highest breeding value in Gisting Atas Village, Gisting District, Tanggamus Regency, namely BG8 (17.20 kg); LS9 (17.16 kg); LS8 (17.16 kg); LJ3 (17.09 kg); and BG (17.06 kg). Meanwhile, there were 5 females with the highest breeding value, namely BG5 (17.03 kg); BG6 (16.93 kg); SU4 (16.86 kg); SU5 (16.86 kg); and MR3 (16.84 kg).
