Abstract

A study was conducted in the Laboratory of Animal Husbandry and Veterinary Science, University of Rajshahi, Rajshahi, Bangladesh, during March, 2011 to February, 2012. The aim of this study was to determine the effects of temperature, humidity and rainfall in different months on the prevalence of haemonchosis of goats in Rajshahi, Bangladesh. A total of 720 samples were examined, of these (416) 57.8% goats were found positive for Haemonchus spp. infection. The highest prevalence was observed in the month of July (82.1 %) followed by August (79.7 %) and lowest in the January (28.3 %) followed by February (38.7 %). It was also observed that temperature (29.8°?), relative humidity (86%) and rainfall (146.0 mm) in the month of July was favourable for the egg laying, hatching and survival of infective larvae on the pasture. On the other hand, all the factors like temperature, humidity and rainfall was recorded lowest as 17.5°?, 79%, 5.5 mm respectively which was unfavourable for the reproduction and survival of infective larvae in the month of the January. The current study revealed that haemonchosis is an important and common parasitic disease and requires special attention for its control.  The prevalence among different months when compared statistically (Chi-square test and DMRT) revealed significant (P=0.001) differences. So, it is concluded that, month of the year, temperature, humidity and rainfall has significance effect on the prevalence of haemonchosis in goats. Considering those factors control should be carried out in and around Bangladesh to improve our goat production.
