Abstract:
Livestock diseases incur huge cost on the farmers in the form of decreased productivity, mortality, control treatment and other shadow price such as the value of the offspring that could have been born. The understanding of the seasonal pattern and variation in disease incidence will show implications towards planning efficient disease control programme and vaccination. The present study analysed the pattern of incidence of major livestock diseases in Meghalaya over the years (2010-2015), the characteristics of its incidence within a year and discuss the effects of trade and environment on the seasonality of these diseases. Lorentz curves and corresponding Gini Coefficients showed that the distribution of all the eight diseases within a year were non-uniform, highest variation being observed in Caprine FMD. Near to equal distributions throughout the year with non-distinct peak were observed for Swine Fever, Bovine BQ and Bovine HS. The monthly seasonality of FMD incidences in bovine, swine and caprine, Swine Fever and Ranikhet Disease were highest in monsoon and least in winter and the seasonality was explained better by the seasonality of the import of these livestock than the environmental factors. While Fowl pox also had the same order of seasonality, the environmental factors seems to be indirectly linked to it, probably through high mosquito activities in monsoon, rather than the volume of import of poultry. Other physical or cultural factors such as seasonal human activities also explain the seasonal incidences of these diseases which needs further investigation.
Highlights
- Infectious diseases are known to show seasonality in its incidence
- Seasonality in the incidence of six viral and two bacterial infectious diseases in livestock and poultry were assessed.
- The study examined and discussed the effects of trade and environment on the seasonality of the diseases.
