Despite this significant contribution, it is predominantly comprised smallholder farmers with few cows providing vital support in terms of food security, household income and employment for millions of farmers. Research aimed at enhancing productivity and sustainability in these smallholder dairy systems is crucial for rural development, increasing farm incomes, creating employment and supporting women and youth. However, a major challenge is the absence of a routine performance data collection system. Previous efforts to address this limitation often relied on methods from well-established dairy systems in developed countries which frequently failed to adapt effectively. Advances in mobile technology have prompted attempts to investigate alternative cost-effective and practical data recording systems in the smallholder dairy farming with a major focus on information and communications technology (ICT). Successful implementation of digital tools for data collection and synthesis to generate management information as feedback to farmers using ICT-based extension tools has led to increased productivity and household income. Additionally, the use of genomic information allows for genetic evaluation with minimal pedigree information and supports the initiation of breed improvement programs for increased productivity.Item Business skills empowerment program through incubation and mentorship for selected pig agripreneurs in Masaka and Mukono districts: process, outcomes and lessons(Report, 2024-10-30) Kamau, Loise; Tugume, Grace; Ahumuza, Ronnie; Marshall, Karen; Ouma, Emily A.The agripreneur business incubation/acceleration program, started in 2023 in Uganda to address challenges associated with market inefficiencies including weak linkages between pig farmers, pig aggregators and input and service providers; poor business practices by artificial insemination (AI) technicians/animal health service providers and limited networks to enable optimal business operations. The objective of the business incubation/acceleration program focused on both the supply side (agripreneur focused) and the demand side (farmer focused) as follows: Supply side: • To empower the pig agripreneurs specifically AI service providers and pig aggregators through business skilling and mentorship • To strengthen the linkages between the pig agripreneurs and finance institutions to enhance access to finance for business upgrading through better business practices • To enhance the linkages between the pig agripreneurs, pig farmers, finance institutions and other business development services through an online networking platform Demand side: • To catalyse demand for the inputs and services delivered by the agripreneurs by sensitizing pig farmer groups on the necessary inputs and services required to run the pig enterprise as a business, and how to bargain for better terms through collective action.Item Digital applications enhanhancing livestock genetic improvement in low-input systems(Presentation, 2024-12-27) Ojango, Julie M.K.; Okeyo Mwai, AllyItem Adapting an Entrepreneurial Ecosystem approach for Climate-Smart Small Ruminant Production in Pastoral Communities(Presentation, 2024-12-10) Oyieng, Edwin; Sila, Winfred; Ojango, Julie M.K.Item Home gardens make nutritious food accessible in Ethiopia(Blog Post, 2024-08-26) Ebrahim, Mohammed; Tesfaye, Getachew; Tamene, Lulseged; Tessema, Fikadu; Alene, Temesgen; Tilaye, Asmalu Tarekegn; Abebe, Tewodros; Seifu, HaimanotItem An inclusive scaling business model for transforming traditional small scale poultry production to market oriented production.

Implementing AI reproductive techniques improves production conditions, lowers costs, and increases efficiency. The CGIAR initiative on Sustainable Animal Productivity for Livelihoods, Nutrition and Gender Inclusion (SAPLING) under the innovation package 1 sought to improve access to farmer preferred pig breeds through artificial insemination. The intended outcome being a strengthened pig genetic resource value chain through business models for AI service providers and potentially semen suppliers + capacity building of actors.Item Evaluating reproduction traits in a crossbreeding program between indigenous and exotic sheep in semi-arid lands(Journal Article, 2025-01-01) Oyieng, Edwin P.; Ojango, Julie M.K.; Gauly, M.; Mrode, Raphael A.; Dooso, Richard; Okeyo Mwai, Ally; Kalinda, C.; König, S.Reproduction traits are important factors determining the efficiency of any sheep production system. This study evaluates the age at first lambing (AFL), lambing interval (LI), litter weight at birth (LBWT), litter weight at weaning (LWWT), birth weight of ewe (EBWT) and weaning weight of ewes (EWWT) in a crossbreeding program between the Red Maasai (RRRR) and Dorper sheep and their crosses, 75% Dorper and 50% Dorper (DDRR) breeds. All the traits significantly (P < 0.05) differed across breeds and season of birth of the ewe. LBWT and LWWT were significantly affected by the sex of the lamb, type of birth of the lamb and parity in which the lambs were born in. AFL and LI had very high environmental variances. Overall heritability estimates of AFL (0.09 ± 0.04) and LI (0.00 ± 0.01) were not significant from zero while the heritability estimates for EBWT (0.38 ± 0.04), EWWT (0.23 ± 0.03), LBWT (0.19 ± 0.03) and LWWT (0.09 ± 0.02) were significant (P < 0.05). The RRRR had the highest genetic gain for all traits while the DDRR had a higher genetic gain among the crosses. LI had negative genetic correlations with LBWT (−0.53 ± 0.08) and LWWT (−0.28 ± 19.59) while AFL had positive genetic correlations with LBWT (0.27 ± 0.46) and LWWT (0.31 ± 0.34). The phenotypic trends for AFL and LWWT showed a negative and positive association, respectively, with the rainfall index over the years. With proper farm management, improved reproduction performance of ewes is possible by indirect selection using LBWT and LWWT for the Red Maasai, Dorper and their crosses within the semi-arid lands.Item History and genetic diversity of African sheep: Contrasting phenotypic and genomic diversity(Journal Article, 2025-02-01) Da Silva, A.; Ahbara, A.; Baazaoui, I.; Jemaa, S.B.; Cao, Y.; Ciani, E.; Dzomba, E.F.; Evans, L.; Gootwine, E.; Hanotte, Olivier H.; Harris, L.; Li, M.-H.; Mastrangelo, S.; Missohou, A.; Molotsi, A.; Muchadeyi, F.C.; Mwacharo, J.M.; Tallet, G.; Vernus, P.; Hall, S.J.G.; Lenstra, J.A.Domesticated sheep have adapted to contrasting and extreme environments and continue to play important roles in local community-based economies throughout Africa. Here we review the Neolithic migrations of thin-tailed sheep and the later introductions of fat-tailed sheep into eastern Africa. According to contemporary pictorial evidence, the latter occurred in Egypt not before the Ptolemaic period (305–25 BCE). We further describe the more recent history of sheep in Egypt, the Maghreb, west and central Africa, central-east Africa, and southern Africa. We also present a comprehensive molecular survey based on the analysis of 50 K SNP genotypes for 59 African breeds contributed by several laboratories. We propose that gene flow and import of fat-tailed sheep have partially overwritten the diversity profile created by the initial migration. We found a genetic contrast between sheep north and south of the Sahara and a west–east contrast of thin- and fat-tailed sheep. There is no close relationship between African and central and east Asian fat-tailed breeds, whereas we observe within Africa only a modest effect of tail types on breed relationships.
