Through a diagnostic survey and feeding trials (Aleta Chuko Woreda, SNNPRS), availability of common feed resources and effect of sweet potato vine hay (SPVH) and concentrate (50%wheat bran +50% noug cake) supplementation to local bucks on growth performance were assessed at farmers’ management levels. Out of 150 households (HHs) interviewed it was found that natural pasture, crop residues, fodder tree and industrial by products are main feed resources; livestock are mainly kept for milk production and income but small ruminants only for income and average livestock holding per HH was 6.69 TLU. Yearling bucks (16.9 ± 3.21 kg) were assigned into four treatment diets in a RCBD design. One animal from each of four treatment diets were given to each of four farmers selected. Bucks were grazing natural pasture from 8:00 to 17:00h and supplemented with 88g concentrate (T1), 88g concentrate + 171.2 g SPVH (T2), 88g concentrate +316.9 g SPVH (T3) and 88g concentrate + 461.3 g SPVH (T4) on DM basis. Goats under T2, T3 and T4 consumed higher (p < 0.001) total DM than those of T1. The DM (88, 259, 405 and 549), OM (75, 217, 335 and 455), CP (23, 49, 72 and 91), NDF (37, 97, 148 and 199) and ADF (20, 58, 90 and 122) intakes and daily weight gain (32, 48, 58 and 69g/head/d) increased (P < 0.05) with increasing level of supplementation of SPVH (T1, T2, T3 and T4, respectively). It can be concluded that supplementing bucks up to 461gDM/head/d SPVH gave highest growth rate.
