Abstract Pakistan is among the largest goat producing countries in the world exhibiting rich diversity between and within goat breeds. The implementation of any genetic improvement intervention for such a diverse goat population requires a clear definition of breeding objectives and selection criteria, tailored to the needs of goat farming community. Appreciating the importance and diversity of the Beetal goats, this study was designed to identify the selection criteria and consequently, to define the breeding objectives of the four strains of Beetal goats, namely Beetal Faisalabadi, Beetal Makhi-Cheeni, Beetal Nuqri, and Beetal Rahim Yar Khan. A participatory approach was used for this purpose. A questionnaire was developed, and a survey was conducted at four sites of the Punjab province of Pakistan: Faisalabad/Sahiwal, Bahawalpur/Bahawalnagar, Rajanpur, and Rahim Yar Khan. The Beetal goat breeders (n = 162) were asked to rank the traits of their selection criteria and breeding objectives were then inferred based on the relative importance of the selected traits. The prevailing production system was also characterized by the breeders. Data obtained from the survey were subjected to statistical analysis using the R programming language. Although the results showed diversity in the selection criteria opted by the breeders of the different strains, the convergence of the criteria was possible. Overall, the preference of morphological traits was highlighted. Nose shape, body length, udder size, ear size and body color emerged as the most preferred selection traits. Adaptation of subjective rather than objective selection criteria was evident. The production of animals with certain morphological attributes along with improved meat and milk production constituted the breeding objectives of the breeders.

参与式方法确定的四种巴基斯坦甜菜山羊品种的育种目标和选择标准

摘要 巴基斯坦是世界上最大的山羊生产国之一,在山羊品种之间和内部表现出丰富的多样性。对如此多样化的山羊种群实施任何遗传改良干预措施都需要明确定义育种目标和选择标准,以满足山羊养殖社区的需求。认识到 Beetal 山羊的重要性和多样性,本研究旨在确定选择标准,从而确定 Beetal 山羊四种品系的育种目标,即 Beetal Faisalabadi、Beetal Makhi-Cheeni、Beetal Nuqri 和 Beetal Rahim亚尔汗。为此目的采用了参与式方法。编制了一份问卷,并在巴基斯坦旁遮普省的四个地点进行了调查:费萨拉巴德/萨希瓦尔、巴哈瓦尔布尔/巴哈瓦尔纳加尔、拉詹普尔和拉辛亚尔汗。Beetal 山羊育种者(n = 162)被要求对其选择标准的性状进行排名,然后根据所选性状的相对重要性推断育种目标。盛行的生产系统也以育种者为特征。从调查中获得的数据使用 R 编程语言进行统计分析。虽然结果表明不同品系育种者选择的选择标准存在多样性,但标准的趋同是可能的。总体而言,突出了形态特征的偏好。鼻子形状、体长、乳房大小、耳朵大小和体色成为最优选的选择特征。主观而不是客观选择标准的适应性是明显的。
