Data limitation on input allocation has limited agricultural economists in measuring sub-sector productivity growth in agriculture. However, recent developments allow now to estimate total factor productivity (TFP) growth for crops and livestock accounting for input-output allocation. This paper extends previous work on TFP measurement for livestock into ruminants and nonruminant (pigs and poultry) productivity measurement, given the differences in productivity growth rates among these species. The results show the non-ruminant sector as more dynamic than the ruminant sector, with poultry driving most of the growth in that sub-sector. Given these rates of productivity growth, non-ruminant productivity in developing countries may be converging to the productivity levels of developed countries.
