The livestock sector in Zimbabwe has changed with the redistributive land reform programme. Land was distributed under two establishment models the A1 and the A2. Whilst A1 farmers are under common grazing and operate same as smallholder farmers, A2 resettled farmers were and are supposed to carry out and revive the commercial farming activities. Land redistribution was done with the objective of giving land to the landless; however, questions arise as to how this programme affected or influenced the beef value chains. The distribution of the fast track land reform programme shaped and restructured beef value chains in such a way that there was an entrance and egression of different chain actors. This review evaluates beef value chains in the A2 farms with reference to former commercial farms, how their entrance has changed market trend, chain actors, chain supporters and all the other stakeholders involved in the beef value chains. © 2015 Fundacion CIPAV.

Development of communal cattle production can be a sustainable way to improve the livelihoods of the rural population in Zimbabwe. There is however, little information and research conducted to characterize, understand and develop the communal cattle production systems in Zimbabwe. This review focuses on the importance of communal cattle production, constraints to sustainable production and research needs necessary to improve the production systems. Communal cattle production in Zimbabwe is extensive and dominated by indigenous cattle which are adaptable to the local environment. Their important functions, which include provision of food security and socio-cultural role, are discussed. The major constraints identified are high disease and parasite prevalence, low level of management, limited dry season forage availability and poor marketing management. Any improvement in these constraints may lead to a sustainable increase in communal cattle production. Source

In complex mixed crop-livestock systems with limited resources and biomass scarcity, crop residues play an important but increasingly contested role. This paper focuses on farming systems in the semi-arid areas of Zimbabwe, where biomass production is limited and farmers integrate crop and livestock activities. Conservation Agriculture (CA) is promoted to intensify crop production, emphasizing the retention of surface mulch with crop residues (CR). This paper quantifies the associated potential economic trade-offs and profitability of using residues for soil amendment or as livestock feed, and explores alternative biomass production options. We draw on household surveys, stakeholder feedback, crop, livestock and economic modeling tools. We use the Trade-Off Analysis Model for Multi Dimensional Impact Assessment (TOA-MD) to compare different CR use scenarios at community level and for different farm types: particularly the current base system (cattle grazing of maize residues) and sustainable intensification alternatives based on a CA option (mulching using maize residues norganic fertilizer) and a maize-mucuna (Mucuna pruriens) rotation. Our results indicate that a maize-mucuna rotation can reduce trade-offs between CR uses for feed and mulch, providing locally available organic soil enhancement, supplementary feed and a potential source of income. Conservation Agriculture without fertilizer application and at non-subsidized fertilizer prices is not financially viable whereas with subsidized fertilizer it can benefit half the farm population. The poverty effects of all considered alternative biomass options are however limited; they do not raise income sufficiently to lift farmers out of poverty. Further research is needed to establish the competitiveness of alternative biomass enhancing technologies and the socio-economic processes that can facilitate sustainable intensification of mixed crop-livestock systems, particularly in semi-arid environments. © 2014 Elsevier Ltd.

Despite the importance and opportunities that cattle present to smallholder farmers, their productivity remains low. High mortality and low fertility mainly caused by feed and health related factors are the reasons of low cattle productivity in semi-arid Zimbabwe. Mortality is unproductive as cattle that die, die with the feed that they eat. As most of the rain water is used for feed production through transpiration, mortality wastes it and lowers livestock water productivity (LWP). In this study we characterize the existing situation of feed, health, herd size and assess the impact of mortality and fertility on cattle production in semi-arid western Zimbabwe. The data were collected using household surveys and participatory rural appraisals (PRAs). Farmers were categorized into poor and better-off cattle keepers'wealth groups. A simulation approach using the DynMod model was applied to evaluate the extent livestock production and LWP can be improved by reducing mortality and increasing fertility of cattle from the wealth groups. Mortality was relatively high amongst the different classes of stock with an overall mortality rate of 0.17. Fertility was low with parturition rate of 0.48 on average. The projection of the current system showed a decline in cattle numbers for the poor and better-off farmers. For better-off farmers' cattle, mortality rate in absolute terms was higher than the poor farmers' cattle. Complex management with larger herds could be the reason for this trend. Reducing the mortality while increasing parturition rates improved cattle production for both poor cattle farmers and better-off cattle farmers despite the introduction of droughts after every 5years.We observed that as feed consumption increases with cattle numbers, the LWP index also increases. This results in effective utilization of feed resources. Addressing livestock management needs to be intensified as it was noted as an area of concern to address mortality and fertility challenges. Most farmers (64%) graze their crop residues in situ reducing fodder utilization. None of the farmers grow improved legumes and cereal forages for animal feeding during the dry season. Whereas, it was evident that feed shortages did not directly result in mortality except during prolonged drought when their immunity is compromised. Improving the extension services and better access to information, inputs and technologies on cattle production could have a strong impact on improving cattle productivity. Source

A study was carried out to establish non genetic factors affecting milk, butterfat and protein yields in Zimbabwean Red Dane cattle. A total of 1325 unedited 305-day lactation records were obtained from Zimbabwe Livestock Identification Trust herd, with cows calving in the period 2002-2006. The Henderson Type III sum of squares in Genstat edition 14 program was used. Parity, days in milk, year of calving and age of calving had significant effects (P< 0.05) on milk, fat and protein yield; milk yield; protein and fat yield; and milk and protein yield respectively. An increase in parity resulted in an increase in milk yield and composition up to parity 4 and started declining in parity 5. An increase in days in milk also resulted in an increase in milk yield whereby the milk yield increased at a declining rate as from 350 days to 550 days. Milk yield and composition declined in 2005 and there was a decline in protein yield from 2006 to 2009. Lastly, milk and protein yield resulted in a gradual increase up to 58 months followed by a declining trend up to 103 months. Month of calving and days dry did not have significant effects (P> 0.05) on milk yield and composition of Red Dane cattle in Zimbabwe. The study showed that non-genetic factors have a significant effect on milk yield and composition of Red Dane cattle in Zimbabwe. Source
