Résumé partiel
The study was conducted in Arbaminch Zuria and Mirab Abaya districts of Gamogofa Zone of SNNPRS of Ethiopia. The objectives of the study were to assess goat production and marketing system, identify and prioritize goat production and marketing constraints and opportunities, and evaluate the effect of supplementing with the leaves of Balanites aegyptiaca and maize grain on growth performance & economic return of indigenous goats in the study area. The study involved 2 parts. The survey part of the study assessed goat production and marketing system using cross sectional survey, focus group discussion and key informants interview. A total of 120 representative households (2 districts x 2 Agroecology x 2 PA x 15 households) were selected for the study following multi-stage stratified sampling, the action research part evaluated growth performance and economic return of indigenous bucks supplemented with maize grain and leaves of Balanites aegyptiaca. Thus, 20 intact 8-10 month age indigenous bucks with an average initial body weight of 16.13±0.3kg (Mean± SE) were drawn from volunteer goat producers. The bucks were blocked into five blocks/farmers of four bucks based on initial BW and randomly assigned to one of the four treatment feeds within a block/farmer allowing five bucks per treatment feeds. Dietary treatments consisted of feeding natural grass hay ad libitum supplemented with 50g wheat bran (T1) ; feeding natural grass hay ad libitum supplemented with mixtures of 50g wheat bran and 200g cracked maize grain (T2) ; feeding natural grass hay ad libitum supplemented with mixtures of 50g wheat bran and 200g dried leaves of Balanites aegyptiaca (T3), and feeding natural grass hay ad libitum supplemented with 50g wheat bran, and mixture of 200g of dried leaves of Balanites aegyptiaca and cracked maize grain at 1:1 ratio (T4).The experiment was laid down using randomized complete block design. According to the respondents, income generation was the primary reason for keeping goats with the highest index values of 0.277 followed by saving, use of manure, as social capital and meat consumption with an index values of 0.269, 0.177, 0.163 and 0.114, respectively. Road side browsing ranked as the first source of feed for goats according to the average rank results from interviewed households with the highest index value of 0.246 and followed by Communal and private browsing lands with an index values of 0.229 and 0.227, respectively. Among the available water sources, rivers contribute the highest 40% of the water required for goats
