Participatory identification of breeding objective traits and selection criteria for indigenous goat of the pastoral communities in Ethiopia

摘要

A structured questionnaire, own-flock ranking experiment, and group discussions were undertaken to assess goat breeding practices and to identify traits of interest for genetic improvement of indigenous goats. Four pastoral villages in Ethiopia, namely, Jarso, Mesoya, Eleweya, and Dharito were selected based on their goat production potential, accessibility, and suitability to implement community-based breeding programs. A survey and flock ranking experiment involving 70 households and 199 goats were used. In flock ranking experiment, goat owners were asked to choose the first three superior and the worst doe within their own flock. They were also asked to provide their reason for ranking the animals. In addition, data on size traits, kid growth, kid survival, reproduction traits, and milk yield were recorded for each doe. Data obtained from questionnaire, flock ranking, and measurements were subjected to both qualitative and quantitative analysis. Large variation was observed between top and last ranked does in most of the traits and price, for example, in body weight (33.6 +/- 0.88 vs. 25.2 +/- 0.93 kg), doe's kid survival (92.1 +/- 4.01 vs. 59.6 +/- 4.48%) and doe's price (1367 +/- 46.5 vs. 833 +/- 46.9 (US$1 = 28.4 Ethiopian Birr) Ethiopian Birr). Mobility is practiced with a defined and known pattern; therefore, recruitment of mobile enumerators for data recording would assist in implementation of breeding programs. Breeding objective should emphasize mothering ability (kid growth and survival), milk yield of does, and coat color in all areas. Due to its good correlation with other traits like kid growth and pre-weaning kid survival, considering milk yield alone as selection criteria or giving more weight for milk yield in the breeding program could generate better genetic benefit. Setting-up breeding program should be based on full participation and context of pastoralists.
