Population Performance of Saburai Goat at Saburai Goat Breeding Area, Tanggamus regency, Lampung Province

Abstract

The survey method was conducted to investigate the population performance of the Saburai goat breeding area in Tanggamus Regency, Lampung Province. The population performance was evaluated based on natural increase (NI) and the ability of the region to supply Saburai breeds and based on net replacement rate (NRR). Direct observations were made since the Saburai goat was designated as the Lampung Province’s local genetic resource based on the Decree of the Minister of Agriculture of the Republic of Indonesia Number 359 / Kpts / PK.040 / 6/2015 until 2018. The result showed that the population of Saburai goat in 2015, 2016, 2017 and 2018 were 1,469, 2,369, 2,860, and 3,293 tails, respectively. The average length of use of male and female goats was 4.44 ± 0.20 and 5,033 ± 0.21 years, respectively. The highest needs of replacement stock was in 2018 (5.40% for males and 5.47% for females). The average percentage of births of male kid was 9.72 ± 6.57% and female kid was 19.72, ± 5.18%. The NI value for male goat was 9.25% ± 6.23% and for female goat was 19.13 ± 4.22%. The highest NRR value for male goat occurred in 2015 (1028.21%) and for female goat in 2016 (528.34%). It could be concluded that the population performance of the Saburai goat from 2015 to 2018 was in a good category and was able to provide replacement stock from its own territory.
