Milk Market

At the attainment of Zimbabwe’s independence, government of Zimbabwe established the smallholder dairy development programme to encourage smallholder farmers to participate in formal milk markets. Although now more than three decades since the government established this programme, smallholder contribution to the national formal market remains low at 5%. This study was undertaken to determine factors affecting milk market participation and volume of sales to milk collection centres of the smallholder dairy value chain. Four smallholder dairy schemes were purposively selected on the basis of whether the scheme participated in the semi-formal or formal dairy value chain. A total of 185 farmers were then selected through simple random sampling and interviewed using a pretested structured questionnaire. Data were analysed using descriptive statistics and Heckman two-stage selection econometric models. Results show that resources (represented by dairy cows, household size), knowledge (educational level, access to information and extension), experience (household head age) and agro-ecological region significantly determined farmers’ participation in milk markets. The study also shows the determinants of milk sales volumes to be resources (number of dairy cows and landholding size); market access (distance to milk collection centre); ambition of the farmer (age); and natural climatic conditions (agro-ecological region). Government policy interventions therefore need to be targeted at increasing the number of dairy cows, taking into account landholding and market access, targeting educated, young farmers located in agro-ecological regions I and II, providing them with adequate, appropriate information and extension packages in order to enhance milk market participation and volume of sales.

Dairy cow cleanliness provides information about animal welfare, along with risk of diseases and quality of housing environments. This study determined animal- and farm-level factors associated with upper hind leg cleanliness in smallholder dairy cows. All lactating cows (n=234) on 118 randomly selected zero-grazing fams participated in this cross-sectional study between May to August 2015 in the Naari area of Meru County, Kenya. Cleanliness scores of hind legs were assessed visually on a 1-4 ordinal scale (clean to very soiled). Potential risk factors for poor leg cleanliness were evaluated by inspection of cows and their housing, along with a questionnaire about herd management. Descriptive statistics, and univariable and multivariable logistic regression were used to determine factors associated with soiled legs (cleanliness score>2) in the analyses. Prevalence of soiled legs was 59.0% (137/234). In the final model, factors positively associated with soiled legs included failure of the knee wetness test on the stall floor (OR=11.2; 95%CI: 5.1, 24.7), animal restlessness in the stall (OR=4.9; 95%CI: 1.8, 13.5), and milk production in kg/cow/day (OR=1.09; 95%CI: 1.02, 1.16). Protective factors for soiled legs included having stalls without excessive space (OR=0.25; 95%CI: 0.11, 0.57), and having an intact stall roof (OR=0.34; 95%CI; 0.15, 0.76). Our results suggest that farmers should address both housing design (especially the roof and stall size) and management issues (especially stall cleanliness) to enhance leg cleanliness and animal welfare.
