摘要

了解生产系统和育种目标是设计就地保护和基因改良计划的前提。本研究旨在描述山羊的育种实践和相对重要性,并确定山羊饲养者的育种目标。数据通过三种方法收集:正式的个人访谈、活体动物形态特征测量和自有羊群排序法。数据分析采用了多种 SAS 程序。结果显示,山羊是仅次于牛的第二大经济重要牲畜物种。创收和家庭肉类消费是饲养山羊的主要原因。交配方式为无控制的自然交配。大多数(90%-100%)山羊饲养者选择公山羊和母山羊作为下一代的父母。通过个人访谈法,确定了毛色、体型外貌、产羔能力、产奶量和羔羊生长情况作为繁殖母羊的育种目标。同样,选择公羊最关键的特征是生长、体型和毛色。根据动物排序法,毛色、体型外貌、产奶量、缠绕能力和母性是最重要的性状。动物的等级与形态特征的表型和市场价格一致。总之,毛色、体型外貌、产奶量和缠绕能力被认为是最重要的性状。因此,这些育种目标可作为设计该山羊群体遗传改良计划的参考。

Participatory definition of breeding objectives and breeding practice for goat population in northeastern Ethiopia: An input for in-situ conservation and genetic improvement program

Knowing the production system and breeding objectives is a prerequisite for designing in-situ conservation and genetic improvement programs. This study aimed to characterize goats' breeding practices and relative importance and identify goat keepers' breeding objectives. Data were collected through three approaches: formal personal interviews, measurement of morphological traits of live animals, and own flock ranking methods. Several SAS procedures were used to analyze the data. The result revealed that goats were the second most economically important livestock species next to cattle. Income generation and home meat consumption were the major reasons for keeping goats. The mating method was an uncontrolled natural mating method. Most (90–100%) goat keepers select male and female goats to be a parent for the next generation. Coat color, physical appearance, twinning ability, milk yield, and kid growth were identified as breeding objectives for breeding females through the personal interview method. Similarly, the most crucial traits for selecting a buck were growth, physical appearance, and coat color. Based on own animal ranking method, coat color, physical appearance, milk yield, twining ability, and mothering ability were the most important traits. The rank of animals was in line with the phenotype of morphological traits and market price. In conclusion, coat color, physical appearance, milk yield, and twining ability were identified to be the most important traits. Therefore, these breeding objectives can be used as input for designing a genetic improvement program for this goat population.

期刊介绍: Ecological Genetics and Genomics publishes ecological studies of broad interest that provide significant insight into ecological interactions or/ and species diversification. New data in these areas are published as research papers, or methods and resource reports that provide novel information on technologies or tools that will be of interest to a broad readership. Complete data sets are shared where appropriate. The journal also provides Reviews, and Perspectives articles, which present commentary on the latest advances published both here and elsewhere, placing such progress in its broader biological context. Topics include: -metagenomics -population genetics/genomics -evolutionary ecology -conservation and molecular adaptation -speciation genetics -environmental and marine genomics -ecological simulation -genomic divergence of organisms
