Solar powered technologies for the smallholder dairy industry in Malawi

The study assesses proposed solar-powered dairy production technologies for smallholder dairy production systems in Malawi; evaluates the quantity and quality of milk produced; assesses socio-economic and gender impacts of the technologies, and promotes the uptake of the technologies. The introduction of a solar-powered water pump greatly reduced the amount of time spent fetching water for the dairy farm; solar milking machines (SMM) had the lowest milking time per cow. There were no significant differences between average milk yields per cow from machine milking and hand milking. The use of solar-powered groundwater pumps ensures a steady and easily accessible water supply

Determinants of smallholder farmers’ perceptions of impact of climate change on beef production in Malawi

Climate change is projected to intensify and smallholder farmers will be the most affected because they entirely rely on climate-sensitive livelihoods and have low adaptive capacity. Appropriate coping strategies for smallholder farmers depend on an accurate description of the effects of agro-ecological and farmers’ socio-economic factors on climate change. A total of 182 structured questionnaires were administered to determine socio-economic factors affecting smallholder farmers’ perceptions of impacts of climate change on beef production in Malawi. Male heads had a higher perception of having increased cattle feed intake and decreased mortality than female heads suggesting that the former had better control and access to animal feed and health resources. Young farmers had a greater perception of experiencing decreases in cattle water supply than adults implying that they lacked experience required to cope with water scarcity. More educated household heads had a higher perception of experiencing decreased tick loads and increased cattle sales than less educated household heads as they are posited to have increased knowledge of parasite control and understanding of market dynamics and expected to make better marketing decisions. High-income farmers had a lower perception of having decreased rangeland biomass and growth rates than low-income farmers indicating that they had capital to acquire resources required to improve rangeland and cattle production. Gender, age, education and income level were the major socio-economic factors that influenced farmers’ perceptions of impact of climate change on beef production. This highlights the importance of incorporating socio-economic factors when devising climate change adaptation and vulnerability reduction strategies for smallholder beef producers

Intake, digestibility, rumen protein synthesis, and growth performance of Malawi Zebu steers fed diets containing rangeland-based protein sources

The study evaluated effects of feeding Malawi Zebu steers with diets containing baobab (Adansonia digitata) seed meal and white thorn tree (Vachellia polyacantha) leaf-meal as alternative protein sources to soybean meal on dry matter intake (DMI), total tract nutrient digestibility, rumen microbial nitrogen supply and growth performance. Thirty Malawi Zebu steers (181 ± 21.4\ua0kg and 29\ua0months), put into individual pens, were randomly assigned to three treatments (10 steers per treatment) made up of rangeland hay and maize bran with either baobab seed meal (baobab diet), V. polyacantha leaf-meal (Vachellia diet), or soybean meal (soybean diet, control) as the protein source. Steers fed the soybean and baobab diets had higher (P ≤ 0.05) DMI, final BW, average daily gain (ADG), and total tract nutrient digestibility of DM, NDF, CP and crude fat than those fed the Vachellia diet. Steers fed the soybean diet had the highest feed conversion ratio followed by those fed the baobab and Vachellia diets, respectively (P ≤ 0.05). Steers fed the baobab diet had the highest rumen microbial N followed by the soybean- and Vachellia-fed steers in that order (P ≤ 0.05). Steers fed the baobab diet had higher microbial N supply, comparable DMI, ADG, FCR, and nutrient digestibility to the soybean diet. The baobab seed meal could be an alternative protein source to the soybean meal for beef production in Malawi
