There is growing recognition that sustainable development of smallholder agriculture in Sub-Saharan Africa requires a systems approach. One response to this has been applying the agricultural innovation systems concept and the use of Innovation Platforms (IP) as tools for agricultural development. By providing social space and facilitating interactions among farmers, researchers and other stakeholders, IPs can promote collective action and foster innovation.

The integration of leucaena into goat production systems in the tropics and subtropics is reviewed. Goats are well adapted to leucaena, and able to be productive on diets containing up to 100% leucaena as a result of bacterial and hepatic detoxification. Incorporation of leucaena into goat production systems can improve liveweight gains, milk production, worm control and reproduction. Successful feeding systems for goats can be based on both grazed silvopastoral systems and cut-and-carry intensive systems, although there is a lack of farming systems research examining the integration of leucaena into goat production systems, or documentation of the practicalities of these practices.

Resumen La integración de leucaena en los sistemas de producción de caprinos en el trópico y subtrópico es revisado en este trabajo. Los caprinos están bien adaptados al consumo de leucaena y son capaces de ser productivos en dietas que contienen hasta un 100% de leucaena como resultado de la detoxificación bacteriana y hepática. La incorporación de leucaena en los sistemas de producción caprina tiene el potencial de mejorar las ganancias de peso vivo, la producción de leche, el control de parásitos internos y la reproducción. Sistemas de alimentación exitosos para caprinos pueden basarse tanto en pastoreo en sistemas silvopastoriles como en sistemas intensivos de corte y acarreo. Sin embargo, hay una escasa investigación sobre sistemas agropecuarios que examinen la integración de leucaena en los sistemas de producción caprina, y de documentación de aspectos prácticos de esta integración. Palabras clave: Caprus aegagrus hircus, corte y acarreo, leguminosas arbóreas, pastoreo, sistemas silvopastoriles.

This paper reviews experiences with cross-breeding for milk production in the tropics. Data were compiled from 23 different studies evaluating the performance of different grades of cross-bred animals as well as local breeds. Relative performance of indigenous breeds compared with different grades of cross-breeds was calculated for three climatic zones. Traits considered were milk yield per lactation, age at first calving, services per conception, lifetime milk yield and total number of lactations completed. At 50 percent Bos taurus blood, lactation milk yields were 2.6, 2.4 and 2.2 times higher than those of local cattle in the highland, tropical wet and dry, and semi-arid climatic zones, respectively; lactation lengths increased by 1.2, 1.2 and 1.9 months in the above-mentioned climatic zones, respectively; there was a reduction in calving interval by 0.8 times and in age at first calving by 0.9 times. Similarly, cross-breds with 50 percent B. taurus genes had 1.8 times higher lifetime milk yields and a 1.2 times higher number of total lactations. Although cross-breeding faces a number of challenges such as better infrastructure, higher demand for health care, there are many advantages of using it. These are higher production per animal, higher income for the families and provision of high-value food. It is therefore likely to continue to be an important livestock improvement tool in the tropics in the future, where farmers can provide sufficient management for maintaining animals with higher input requirements and access to the milk market can be secured.

Abstract
Crossbreeding of tropical and western dairy cattle to improve performance on tropical smallholder farms has been widely advocated, criticised and yet applied. Advantages and disadvantages are documented. Only a small number of crossbreeding interventions has been successful. Little is known how successful adopters introduce and develop crossbreeding at farm level. For this study 248 smallholders successfully applying crossbreeding were interviewed using a pre-tested questionnaire in selected regions of Ethiopia, Uganda and India. Qualitative and quantitative data on motivations, crossbreeding introduction, support received, adaptation of breeding strategies and impacts at farm level have been analysed. A first description of local crossbreeding innovation systems has been made. Results show that in all contexts the reason to introduce crossbreeding was to increase profit. External support and other farmers were essential for successful adoption as information sources and suppliers of exotic genetics. Breeding is adapted if possible to increase performance but a lack of understanding of the crossbreeding concept has been identified. Positive and negative impacts led towards a high-input/high-output system. Many context specific challenges had to be overcome by adopters but they perceived crossbreeding as success. The conclusion is that farmers can increase incomes with crossbreeding. The complexity, initial investment and dependence on support and external inputs are probable reasons for slow crossbreeding uptake. Strengthening availability of breeding inputs enabling farmers to reach suitable and sustainable herd performance must be a priority. If investment capital, supply, support and market linkages are accessible, farmers can and will adopt crossbreeding without ignoring inherent challenges. Whether it proves a sustainable strategy for dairy farmers in the study areas has to be proven over time.

Pastoralists of south-west Uganda crossbreed Holstein Friesian bulls with indigenous Ankole cattle. Aim of this breeding strategy is to enhance milk yields. Present diploma thesis wants to find out, if there are differences between pastures stocked with different breeds. Data on pasture management, pasture vegetation, plant traits, pasture productivity and nutrient composition was collected on 10 farms close to Mbarara. Analysis of collected data lead to following results: There are differences in pasture management and in effects of bushes, shrubs and trees between pastures stocked with different breeds. Pastures stocked with Ankole cattle were more likely to be subjected to erosion. Composition of herbaceous pasture vegetation is changing. Problems caused by weeds are independent from herd type a pasture is stocked with. There are significant differences in some plant traits between pastures stocked with different breeds. Fresh and dry matter yields are significantly different but dry matter content did not show significant differences between pastures stocked with different breeds. Of all nutrients analyzed only crude protein content showed significant differences between pastures stocked with different breeds. Various reasons for the occurring differences are discussed. But the most important reason may be the preselection of better pastures for crossbred cattle acknowledged by farmers.

In Uganda local and improved western dairy breeds have been crossbred for over 50 years. Introduced as development tool, like in many other tropical regions, the aim was performance
improvement of local dairy cattle herds to benefit farmers and the dairy sector as a whole. Although the uptake of this breeding strategy has been slow it can be powerful tool for breed improvement. Research has so far not yielded information how farmers succeed with crossbreeding at farm level. This study aims at filling this knowledge gap with data collected in two sites in Kiruhura and Bushenyi districts, Uganda. Therefore a total number of 65 farmers have been interviewed. Results show that in the prevailing setting rossbreeding is a path for development. Income increase expected by farmers was realized. Education and investment potential are supporting introduction of crossbreeding. Strong linkages in the community enable farmers to access breeding stock, information and solutions for challenges and make partly up for the missing links to breeding services and extension. Crossbreeding is adapted at farm level in various ways, mainly to increase performance. Deceptive information on performance development indicating missing important links to breeding services and extension might be a threat to sustainable success with the crossbreeding strategy. We conclude that crossbreeding can support development of dairy
farms. But it requires high inputs of investment, labour and natural resources which questions it’s sustainability in the light of future ecological and socio-economic changes.

Goat and sheep production is important in Fiji and other Pacific Island Countries both culturally and economically. Local producers currently cannot satisfy demand and Fiji alone imports 15.4 US$ worth of goat and sheep meat annually. Both on-farm production and value chains are in need of improvement. These issues concern the ‘Assessment of Markets, and Production Constraints to Small Ruminant Farming in the Pacific’ project, funded by ACIAR. The UNE project team, led by Fran Cowley, in cooperation with local partners have recently conducted field work trying to assess the current state of the small ruminant sector in Fiji. This presentation shared project progress, the initial findings and what next steps for the project in the Animal Science Seminar on September 5th 2017 at the University of New England, Armidale.
