Abstract

To describe the proportion and pattern of culling in commercial Goatherds, this survey was carried out over a period of 18 years from 1996 to 2013 in an industrialized Goatherd. In total, the data of 3945 Goat have been used in this study. Overall, 499 (12%) Goat was culled. The involuntary culling was mainly due to shortage disorders (3.8%), Viral disorders (3.3%), microbial disease (2.8%) and other disorders (2.1%). Due to shortage disorders accounted for 30% of disposals in culled goat. Sheep Pox was the most important reason (64%) for culling due to Viral disorders. Tick Paral Ysis was the most common parasitic disease that contributed to culling, and on average, it was responsible for 88% of parasitic disorders. On the other hand, enterotoxemia accounted for 55% of Microbial disorders. The high proportion of culling due to shortage disorders especially nutritional deficiencies should be considered as an important economic loss and precaution measures are necessary to reduce this loss.
