Abstract/ Executive Summary:

The study was conducted on live and slaughtered goats in Rajshahi district during the period of March, 2011 to February, 2012 by coproscopy and necroscopy studies respectively. The aim of this study was to determine the factors such as age, sex and breed of the goat which influences the prevalence of haemonchosis. The information was collected from farmers through a questionnaire. A total of 720 goats examined, of which 416 goats were found positive for Haemonchus infection and the overall prevalence of haemonchosis in goat was 57.8%. The prevalence rate was found to be higher in young (< 2 yrs), 63.8% compared to older (>2 yrs), 41.5% goats. It was observed that in relation to sex the prevalence of haemonchosis was higher in female, 63.9% compared to male, 50.0% goats. Among the breed, the crossbred goats were the maximum, 60.2% infection rate of haemonchosis than that of Black Bengal, 55.6% goats. The young stage and female goats are more prone to haemonchosis and statistically a significant difference (P<0.05) was noted but there is no significant difference (P>0.05) was found in breed of goats. The present study suggests that young aged and females goats were more susceptible but crossbred goats were slightly susceptible to haemonchosis and requires special attention for its control.

Methodology:

Study plan A cross- sectional study was done to detect the occurrence of parasitic disease in goats in Rajshahi during the period of March, 2011 to February, 2012. Goats were randomly selected from the nearby villages, pastures, veterinary hospitals and abattoirs. A questionnaire was prepared including information viz. name and address of farmer, type of sample, age, sex, and breed of goats for achievement of the study. A total of 720 goats were selected for the present study from which 363 for coproscopy and 357 for necropsy studies in the Rajshahi district. To achieve the goal selected goats were grouped according to the age, sex and breed. Sex of the goats were divided into two groups; female (n=404) and male (n=316) goats. Goats were categorized into two age groups as young animals of < 2 years (n=527) and olders of > 2 years of age (n=193). The age of goats were determined from birth register and examined by teeth and cornual ring reading. On the basis of breed characteristics and ancestor history goats were grouped into Black Bengal/local (n=378) and crossbred (n=342). Collection of sample In the coproscopy studies, faecal samples were collected by a two-finger procedure directly from the rectum of selected goats. Faecal samples were collected in 10% formalin containing suitable airtight containers, such as screw-cap bottles and plastic bags. At necropsy studies, abomasii were collected after slaughtering and evisceration of the goat in nearby slaughter houses in the study area. All the Examination procedure The monthly collection of faecal samples and abomasum were brought to the laboratory at the Department of Animal Husbandry and Veterinary Science, University of Rajshahi for the identification of Haemonchus spp. Faecal samples were examined by direct smear, floatation and sedimentation techniques for the presence of Haemonchus eggs. Haemonchus eggs were identified by using low power microscope according the keys and morphological characteristics [9]. Data analysis All the data that were collected (age, sex and breed) entered to MS excel sheet and analyzed by using SPSS version 19. Descriptive statistics was used to determine the prevalence of the haemonchosis and Chi-square test (χ2) was used to look the significant difference between age, sex and breed of goats with haemonchosis. In all the analyses, confidence level was held at 95% and P<0.05 were set for significance. for 24 hours.

Achievement/Findings:

The older aged, male goat and Black Bengal goats are slightly more resistant in prevalence of haemonchosis in Rajshahi district, Bangladesh. So, young aged, female and crossbred goats should be great care of management during grazing month on the pasture.
