Abstract

A study on "The Existence of Pasundan Cattle Population Based on Inbreeding Depression Value in the Ciletuh-Pelabuhanratu Geopark Area, Sukabumi District" has been carried out in Sukabumi District, West Java, starting on December 19th to December 25th 2020. The aim of this study were to know a Pasundan cattle population in The CiletuhPelabuhanratu Geopark Area and to determine the value of inbreeding depres-sion Pasundan cattle in the Ciletuh-Pelabuhanratu Geopark Area as a basic information for conservation purposes. This research used descriptive method with an explorative approach. Collection of livestock data and farmers is done by survey method. Data was taken from the UPTD Keswan Jampangkulon, Surade and the Livestock Service office of Sukabumi Regency with the verification of sampling data in each sub-district. The method of analysis used is descriptive analysis. The results showed the population structure of the Pasundan Cattle in the Ciletuh-Pelabuhanratu Geopark Area consisted of 5.44% adult males, 55.31% adult females, 12.8% male calves and 26.43% female calves. Pasundan cattle population structure in the Ciletuh-Pelabuhanratu Geopark Area is balanced In this population, inbreeding depression value was 0.7%. These results describe that the inbreeding depression was controlled.
从2020年12月19日至12月25日,在西爪哇素kabumi地区进行了一项“基于近亲繁殖抑制值的帕桑顿牛种群存在”的研究。本研究的目的是了解西列图-佩拉布汉拉图地质公园内的帕桑丹牛种群数量,并确定西列图-佩拉布汉拉图地质公园内近亲繁殖的洼地帕桑丹牛的价值,作为保护的基础资料。本研究采用描述性研究与探索性研究相结合的方法。通过调查方法收集牲畜资料和农民。数据来自UPTD Keswan Jampangkulon、Surade和Sukabumi县畜牧服务办公室,并对每个分区的抽样数据进行了核实。使用的分析方法是描述性分析。结果表明:西列图-佩拉布汉拉图地质公园内的帕桑丹牛种群结构为:成年雄性5.44%,成年雌性55.31%,雄性小牛12.8%,雌性小牛26.43%。西列图-佩拉布汉拉图地质公园地区帕桑丹牛种群结构较为平衡,近交抑制值为0.7%。这些结果说明近交抑制得到了控制。
