Sustainable cowherds require replacement of cull cows either internally via raised heifers or externally with purchased females. Managing raised replacements begins with a weaned heifer calf and continues on through her second pregnancy and calving. Replacement costs were estimated from research conducted in Nebraska for spring-calving cowherds and included the opportunity cost of the heifer calf. The analysis, based on research data, showed that heifer development programs targeted to 50 to 55% of mature BW (MBW) at first breeding can be successful, challenging the traditional target of 65% of MBW at first breeding. The lower BW programs achieved …

Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985-99 was a strong 1.90% per year. Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in productivity. We measure a significant reduction in productivity during political conflicts and wars, and a significant increase in productivity among those countries with higher levels of political …
