Increased Yields and Economic Productivity of Tropical Pig Farms

Abstract

In prospect of a better knowledge of the influence of environment and production system, the yield and economic productivity of 60 pig farms were valued and compared in 3 zones and 3 production systems. The main results showed that the yield per sow (11,18±1,8) is well more important (p<0,05) with the semi-intensive or improved peasant system, compared to traditional peasant system (10,48±1,9) and fully controlled intensive or modern system (10,231,7). The estimated marginal average is higher in Western Highlands (11,14±1,9), followed by humid forest (10,76±1,6) and finally, northern regions (10,42±2,2). Disparities were observed also in all production systems and zones about the sign of the gap. The spread was much more dispersed in the north, with a standard deviation rather higher than the average standard deviation of the sample, indicating a zone favorable to the development of pig production. However, if the traditional peasant system allows to achieve a significantly lower yield than economic productivity in the Western Highlands, it remains the most appropriate in northern regions. Meanwhile, by linking yield and economic productivity, the study highlighted a lack of economic objectivity among farmers. The profitability analysis, as to, revealed that recovery period is relatively short with the modern system, compared to traditional and improved peasant systems but, remains comparable in all production zones.
