Congruence between selection on breeding values and farmers’ selection criteria in sheep breeding under conventional nucleus breeding schemes por Gizaw, Solomon, Getachew, T., Tibbo, Markos, Haile, Aynalem, Dessie, Tadelle

“…A new breeding scheme that integrates the merits of previously suggested schemes has been designed for Menz sheep improvement in Ethiopia. It involves selection based on breeding values in nucleus flocks to produce elite rams, a one-time only provision of improved rams to villagers and a follow-up village-based selection to sustain genetic progress in village flocks. …”

Effect of supplementation of grazing sheep with groundnut cake and wheat bran por Abebe, Yenenesh, Melaku, S., Tegegne, Azage

“…The experiment was conducted to evaluate the effect of groundnut haulm and maize bran mixture supplementations on feed intake, digestibility, body weight gain and carcass characteristics of local sheep fed hay basal diet at Salga sheep farm in Assosa district, Western Ethiopia.The experiment was laid out in a randomized complete block design (RCBD) with four treatments consisting of six blocks with four animals per block based on their initial body weight of 20.12 ± 0.05 kg (mean ± SD).Treatments comprised of feeding natural pasture hay ad libitum T1 = 0; T2 = 100% maize bran (MB); T3 = 50% MB and 50% Groundnut haulm (GNH), and T4 = 100% GNH.The amount of supplements offered was 300 g/day/animal on DM basis.The daily feed intake, daily body weight gain, feed conversion efficiency, dry matter and nutrient digestibility, and carcass characteristics parameters were measured during the experimental period.The study result indicates that the crude protein (CP) contents were 7.12% and 11.6%, and the neutral detergent fiber (NDF) contents were 67.9% and 57.5% for natural grass hay and groundnut haulm, respectively.The total DM intake was higher (P < 0.001) in T4 (941 g/day) followed by T3 (937 g/day), and T2 (934 g/day).However, the control group (T1) consumed relatively higher basal dry matter (DM) (767 g/day) as compared to all other groups.Local Sheep supplemented with T4 had significantly different (P < 0.001) FBW (33.2 vs 24.3 kg), FCE (0.17 vs 0.08) and ADG (156.2 vs 46.4 g/day) as compared to the control group.The mean DM, How to cite this paper:…”

Inter-connection between land use/land cover change and herders’/farmers’ livestock feed resource management strategies: A case study from three Ethiopian eco-environments por Mekasha, A., Gerard, Bruno G., Tesfaye, K., Nigatu, L., Duncan, Alan J.

“…We assessed land use/land cover changes from remotely sensed satellite imagery and compared this with community perceptions on availability/use of livestock feed resources and feed deficit management strategies since the 1973s in three districts representing the pastoral, agro-pastoral and mixed crop-livestock eco-environments of Ethiopia. We found that land use/land cover changes are proceeding in all eco-environments and that transitions are from grasslands, and forest lands to bush/shrub lands and crop lands in the pastoral site (Liben), from bush/shrub lands and grasslands to crop lands in agro-pastoral site (Mieso) and from bush/shrub lands, forest lands and grasslands to crop lands in the mixed crop-livestock site (Tiyo). …”

The use of vaginal electrical resistance to diagnose estrus and early pregnancy and its relation with size of the dominant follicle in dairy cattle por Tadesse, M., Thiengtham, J., Pinyopummin, A., Prasanpanich, S., Tegegne, Azage

“…The use of vaginal electrical resistance (VER) for estrous detection and early pregnancy diagnosis were evaluated using three experiments in dairy cattle, in Ethiopia. VER was measured: 1) during the natural estrous (n = 60) cycle, 2) during estrus induced by GnRH+ PGF 2· (n = 11) and 3) during post insemination in dairy cows synchronized with GnRH+CIDR+PGF 2· (n = 25). …”
