body size and testicular traits of tropically-adapted bucks raised under extensive husbandry in ethiopia.five tropically adapted buck breeds extensively managed in ethiopia were studied to determine possible effects of breed and age on body size and testicular traits. in all, 177 bucks were selected following stratified random sampling, and evaluated in three age groups: <14 months (young), 14-19.5 months (intermediate) and 19.6-24 months (old). the breeds studied were arsi-bale (ab; n = 35), central highlands (ch; n = 33), afar (n = 35), boran (n = 36) and woito-guji (wg; n = 38). in all the three ...200818325007

supplementation with linseed (linum usitatissimum) cake and/or wheat bran on feed utilization and carcass characteristics of arsi-bale sheep.thirty yearling male intact arsi-bale sheep with initial body weight (bw) of 15.5 +/- 0.21 kg (mean +/- sd) were used in 90 days feeding trial, 10 days digestibility trial followed by evaluation of carcass parameters at bokoji, ethiopia. the objectives were to evaluate effects of supplementation with linseed (linum usitatissimum) cake (lsc), wheat bran (wb), and their mixtures at 2:1 and 1:2, respectively on feed intake, digestibility, daily bw gain, and carcass parameters. the five treatments i ...201019876753
