Optimizing breeding structures and related management in community-based goat breeding programs in the Borana pastoral system of Ethiopia

The study simulated different potential breeding programs to design the optimal structure and operational management for Borana goat. It evaluated scenarios using ZPLAN+ software maximize genetic gain, discounted profit determine optimum size of base population a community-based program (CBBP) nucleus. analyzed combinations objective traits in index, assessed effect changing buck doe ratio, impact improved kid survival, determined CBBP. A two-tier based on 577 does CBBP 1,006 surrounding flocks was assumed, where selected bucks were disseminated populations. Combining weight kids at six months (SMWT) lactation milk yield dams (LMY) selection index resulted gain doe−1 generation−1 0.13 kg, 0.58 0.02 0.004 SMWT, LMY, number that survived market age (NKS) born (NKB), respectively. This also generated total US$5.76 over 10 year investment period. result 30 percent higher than when LMY separately 225.7 SMWT separately. addition NKB NKS did not significantly change progress profit. However, further optimization combined by improving mating ratio only, improvement survival rate substantial increase US$11.13 US$15.58 doe−1, respectively maximum attained 3,579 does. accumulated US$14,776 dispersed with unit about nucleus is recommended. In goat community-breeding program, need be an combining least own live dam performance. Essential requirements ensuring sustainability such are discussed paper.
