Item An Assessment of Small Ruminant Production, Marketing, and Investment Options in Somaliland: A System Dynamics Approach(Elsevier B.V., 2023-01) Wanyoike, F.; Rich, K.M.; Mtimet, N.; Bahta, S.; Godiah, L.; International Livestock Research Institute (ILRI) ; Terra NuovaA complex set of factors affect the production and sale of livestock in Somaliland, including feed supply, diseases, and demand, among others. This study constructs a system dynamics (SD) model to simulate the impacts of baseline dynamics and alternative value chain interventions to address inherent constraints. Findings indicate that Somaliland incurs high economic losses due to occasional animal export bans associated with Rift valley fever (RVF) outbreaks (up to 12% of GDP) and lack of pasture during droughts, given the lack of effort by producers to balance their flock sizes with stocking capacity. Under the baseline conditions, prospects for growth of the small ruminants’ sector are poor as the stocking rate is centered and stagnated at about 2.54 million TLUs, and a decline is projected in the long run. In contrast, the adoption of optimization of animal herd sizes in order to balance feed demand with supply could (ceteris-paribus) enhance productivity, boosting exports and domestic supply of slaughter animals and also lead to improved rangeland conditions, ultimately reversing the projected long-run erosion of stocking capacity.Item SDP Costs and feasibility March 2005(Kenya Agricultural Research Institute, 2005) Mwambia, M.; Wanyoike, F.; Kutwa, J.; Staala, S.; Omore, A.; Kenya Agricultural Research InstituteMany farmers in Kenya dwell In areas with poor roads, lack electricity or where cooling is uneconomical. This occasions losses of milk through waste, spoilage inefficiency. Some milk market agents in such remote areas use harmful chemical agents in milk to preserve It. While cooling is still the preferred method of bulk raw milk preservation, an alternative method of preservation using the Lactoperoxidase system (LPS)1 has been developed for use by smallscale farmer groups in poor milk market access regions. The use of LPS has been approved by both the FAOIWHO Expert Committee on Food additives and the Codex Alimentarius Commission. This study sort to determine (i) the financial feasibility of use of LPS compared to milk cooling and lor no preservation at all. (ii) the potential for dairy farmers in the rural areas to increase their profitability by using LPS to preserve and sell their evening milk (iii) the institutional feasibility for use of the LPS technology in milk marketing in Kenya (iv) the potential for it to replace potentially harmful chemicals used to preserve raw milk by some marketing agents.
