Item Meta-analysis of average estimates of genetic parameters for growth, reproduction and milk production traits in goats(Journal Article, 2017-08) Jembere, T.; Dessie, Tadelle; Rischkowsky, Barbara A.; Kebede, K.; Okeyo Mwai, Ally; Haile, AynalemA meta-analysis of 84 published reports on goats was conducted to calculate weighted and unweighted average direct heritability (ha2), maternal genetic effect (hm2), common environmental effect (c2), repeatability (R), genetic (rg) and phenotypic (rp) correlations for growth, reproduction and milk production traits. Weighted average ha2, hm2, and c2 for growth traits ranged from 0.03 to 0.45, 0.05 to 0.27, and 0.02 to 0.10, respectively. Weighted average ha2 for reproduction and milk production traits ranged from 0.00 to 0.17 and 0.15 to 0.22, respectively. Weighted R for the growth, reproduction, and milk production traits ranged from 0.06 to 0.56, 0.06 to 0.13, and 0.50 to 0.61, respectively. Weighted averages of rp and rg among growth traits ranged from −0.06 to 0.84 and 0.01 to 0.98, respectively. Weighted average rp among milk production traits ranged from 0.18 to 0.94. In most cases average ha2 and rg had higher observed standard deviations compared to the theoretical standard error. The present finding revealed that weighted average ha2, hm2, c2, R, and rg are more reliable for two reasons: estimates of ha2 for some growth traits were more conservative than values from relatively higher number of records and the absence of significant effects of the tested fixed factors on some parameter estimates. However, studies on genetic parameter estimations are required for growth, reproduction, and milk traits in goats.Item Navigating upstream-downstream animal health research: Reflections from the Livestock and Fish Program(Brief, 2016-12) Wieland, Barbara; Mohan, Chadag V.; Nene, Vishvanath M.; Toye, Philip G.Item Improving small ruminant productivity and livelihoods through feed and health interventions: Evidence from northern Ghana(Brief, 2016-11-30) Ayantunde, Augustine A.Item Summary of research for development ‘best practice’ technologies validated in the Africa RISING Endamehoni site in Ethiopia, 2013-2016(Report, 2017-03-15) Hailemariam, G.; Ebrahim, M.; Hagos, T.; Mesele, A.; Taye, A.; Meslel, H.; Mekonnen, Kindu; Bezabih, MelkamuItem Interventions and tools to improve small ruminant health in Ethiopia(Brief, 2016-12) Gemeda, B.; Desta, Hiwot; Roesel, Kristina; Okoth, Edward A.; Secchini, F.; Liljander, Anne M.; Wieland, BarbaraItem Pig diseases in Uganda: Impacts on pig production, human health and nutrition(Brief, 2016-12) Dione, Michel M.; Steinaa, Lucilla; Okoth, Edward A.; Roesel, Kristina; Wieland, BarbaraItem LIVES feed value chain development: Approaches and scalable interventions(Presentation, 2016-12-08) Tesfay, Y.; Ebro, A.; Mekasha, Yoseph; Mekuriaw, Z.; Dessalegn, Yigsaw; Gizaw, Solomon; Chala, A.; Tefera, M.; Derso, T.; Teka, W.; Woldemariam, D.; Tilahun, H.; Gebremedhin, Berhanu; Hoekstra, Dirk; Tegegne, AzageItem Major vectors and vector-borne diseases in small ruminants in Ethiopia: A systematic review(Journal Article, 2017-06) Asmare, K.; Abayneh, T.; Sibhat, Berhanu; Shiferaw, D.; Szonyi, Barbara; Krontveit, R.I.; Skjerve, E.; Wieland, BarbaraItem Integrating gender into scaling: Africa RISING science, innovations and technologies in the Ethiopian Highlands(Poster, 2017-01-17) Mulema, Annet A.Item Smallholder farmers’ legume technology adoption preferences and contributions to farmers’ performance: Evidences from N2Africa project(Presentation, 2016-12-08) Getachew, D.; Tegegne, Y.; Kassa, W.; Woldemeskel, Endalkachew; Amanu, T.; Baars, E.Item LIVES poultry value chain development interventions: Approaches and scalable interventions(Presentation, 2016-12-09) Ebro, A.; Mekasha, Yoseph; Gizaw, Solomon; Tesfay, Y.; Mekuriaw, Z.; Dhuguma, G.; Gebremedhin, Berhanu; Hoekstra, Dirk; Tegegne, AzageItem Integrated landscape management: Africa RISING R4D experiences in the Ethiopian highlands(Presentation, 2016-12-08) Tamene, Lulseged D.; Yaekob, Tesfaye; Ellison, J.; Mekonnen, Kindu; Woldearegay, K.; Adimassu, Zenebe; Alene, Temesgen; Dubale, Workneh; Ibrahim, M.; Gurmessa, Biyensa Dubiwak; Tesfahun, G.K.; Thorne, Peter J.Item Decision support tools for farm-level fertilizer recommendation in Ethiopia(Presentation, 2016-12-08) Amede, Tilahun; Asrat, T.; Legesse, G.; Mekonnen, Kindu; Asfaw, A.; Ibrahim, M.; Alene, Temesgen; Dubale, Workneh; Thorne, Peter J.; Tamene, Lulseged D.Item Inoculation and P fertilizer improves food and feed production in grain legumes: Farmers' perceptions and treatment effects on yield and quality of residue biomass in Ethiopian highlands(Presentation, 2016-12-08) Belete, S.; Tolera, Adugna; Bezabih, Melkamu; Woldemeskel, EndalkachewItem The role of irrigated fodder production to supplement the diet of fattening sheep by smallholders in southern Ethiopia(Journal Article, 2016-12-01) Bezabih, Melkamu; Duncan, Alan J.; Mekonnen, Kindu; Adie, Aberra; Khan, A.K.; Thorne, Peter J.Feed shortage and poor quality of available feeds are major constraints for livestock production in the highlands of Ethiopia. A trial was conducted to assess if producing irrigated oat-vetch fodder during the dry period could adequately supplement the diet of fattening sheep and generate additional income for smallholders. A total of 14 farmers and 70 sheep (5 per farmer) were involved in the trial. The farmers supplemented their fattening sheep with 200 g of irrigated oat-vetch fodder per day for about 70 days. The mean daily body weight gain of the fattened sheep ranged from 52 to 110 grams. The partial budget analysis revealed that while farmers with good feeding management could earn an additional income in the range of ETB 55 – 161 per sheep, farmers with the lower rate of weight gain could lose up to ETB 58 per sheep unless purchase and sale prices remained constant. Sheep prices do, however, fluctuate, peaking during major holiday periods occurring during the dry season. Therefore, timing of the fattening period is essential to profitability, and supplemental irrigated fodder production offers smallholders opportunities to produce good quality feed and target favourable markets for fattened animals.Item Africa Research in Sustainable Intensification for the Next Generation: Ethiopian Highlands project, technical report, 1 April 2016-30 September 2016(Report, 2016-10-30) International Livestock Research InstituteItem Evidence based assessment of scalability of agricultural technologies: The case of improved food legumes and small ruminant market sheds(Presentation, 2016-12-08) Tesfahun, G.K.; Thorne, Peter J.; Mekonnen, Kindu; Brooks, K.; Rischkowsky, Barbara A.; Haile, Aynalem; Ahmed, S.; Tamene, Lulseged D.; Degefa, Z.; Yitayih, Mulugeta; Zeleke, F.; Tegegne, AzageItem Partnerships for sustainable intensification research in Africa(Presentation, 2016-11-07) Bekunda, Mateete A.; Larbi, Asamoah; Hoeschle-Zeledon, Irmgard; Mekonnen, KinduItem Africa RISING systems research experiences(Presentation, 2016-11-15) Larbi, Asamoah; Bekunda, Mateete A.; Hoeschle-Zeledon, Irmgard; Bekele, K.; Fischer, Gundula; Thorne, Peter J.; Mekonnen, Kindu; Azzarri, Carlo; Groot, Jeroen C.J.Item Feed innovations for improved livestock productivity in the Ethiopian highlands: Africa RISING experiences(Presentation, 2016-12-08) Bezabih, Melkamu; Mekonnen, Kindu; Adie, Aberra; Thorne, Peter J.
