摘要

杂交的目的是通过引进外来品种提高本地或本土动物的生产力。本研究旨在评估使用 50%布尔公山羊与埃塞俄比亚本土 Woyto-Guji 山羊杂交的效果,并评估农民对杂交后代的看法。数据从埃塞俄比亚南部五个特选地区收集。通过个人访谈、焦点小组讨论(FGDs)和实地观察,收集了有关山羊生产系统和农民看法的信息。研究地区羊群规模的平均值(± SD)为每户 7.31 ± 5.89 头,阿拉巴区的羊群规模更大(10.32 ± 6.56)。研究地区饲养山羊主要是为了创收。首次产仔的平均年龄为 11.3 ± 1.3 个月。在阿拉巴、洛科阿巴亚和古拉格地区,杂交山羊的管理方法相对较好。受访农民高度评价布尔杂交山羊,认为其毛色诱人(4.39 倍,P < 0.001)、行为温顺(3.59 倍,P < 0.001)、生长速度快(1.64 倍,P < 0.05)、市场偏好(5.81 倍,P < 0.001)。然而,在研究地区,易感疾病和干旱被认为是杂交犊牛的缺点。另据报道,在相同的管理制度下,杂交山羊的价格要高于相似年龄组的本地山羊。所有受访农民都对杂交表示出浓厚的兴趣。根据这些调查结果,可以得出结论,波尔杂交山羊在埃塞俄比亚南部表现良好。因此,可以在这些地区继续生产杂交羊。此外,建议考虑其余地区山羊生产者的利益。需要实施综合改良管理系统,以提高杂交后代的存活率。应为山羊饲养者组织可持续的培训计划,重点关注杂交、尽量减少近亲繁殖、公羊轮换、改进饲养和管理方法等方面。

Assessing the Impact of Boer Goat x Indigenous Goat Crossbreeding on Reproductive Performance and Farmer Perceptions in Southern Ethiopia.

Crossbreeding aims to increase the productivity of local or indigenous animals by introducing exotic breeds. This study aims to assess the effects of crossbreeding using 50% Boer bucks crossed with Ethiopian indigenous Woyto-Guji goats and to evaluate farmers' perceptions towards crossbred kids. Data were collected from five purposively selected districts in southern Ethiopia. Personal interviews, focus group discussions (FGDs), and field observations were employed to gather information on the goat production systems and farmers' perceptions. The mean ± SD of goat flock size in the study area were 7.31 ± 5.89 heads per household (HH) with larger flock sizes observed in the Alaba zone (10.32 ± 6.56). Goats in the studied areas were primarily kept for income generation. The average age at first kidding was 11.3 ± 1.3 months. Relatively better management practices were observed for crossbred goats in the Alaba, Loko Abaya, and Gurage zones. Respondent farmers highly appreciated Boer crossbred goats due to their superior perception of attractive coat color (4.39 times greater, P < 0.001), docile behavior (3.59 times greater, P < 0.001), fast growth rate (1.64 times greater, P < 0.05), and market preference (5.81 times greater, P < 0.001). However, susceptibility to disease and drought was considered as drawbacks of crossbred kids in the studied areas. It was also reported that crossbreed goats fetched better prices than indigenous goats of a similar age group and under the same management system. All visited farmers expressed a strong interest in crossbreeding. Based on these findings, it can be concluded that Boer crossbred goats perform well in southern Ethiopia. Therefore, the continued production of crossbred kids can be disseminated to these areas. Additionally, it is suggested to consider the interests of goat producers in the remaining areas. Integrated improved management systems need to be implemented to enhance the survival of crossbred kids. Sustainable training programs should be organized for goat keepers, focusing on aspects such as crossbreeding, minimizing inbreeding, buck rotation, and improved feeding and management practices.
