Economic returns from livestock research and development in Tanzania: 1966-1995.

The objective of this study was to estimate the economic return to public investment in livestock research and development in Tanzania from 1966 to 1995. The supply response model was used to estimate supply elasticities for cattle and small ruminant meat and milk products. The results showed that on average, all commodities were equally responsive to investment in research and development as well as to market prices. All economic profitability measures were positive suggesting that the society gained through investing in livestock research and development. Policies to improve market incentives may increase productivity, reduce risk and encourage farmers to engage in livestock marketing activities.
