Abstract/ Executive Summary:

A study was carried out to estimate the prevalence, species composition and worm burden of abomasal nematodes of goats slaughtered at different abattoir of Thakurgaon district from November 2009 to April 2010. During the study period, 250 abomasum of goats were examined according to standard procedures. Two species of nematodes were identified in goats abomasum with an overall prevalence of 74.00% (n = 250). The specific prevalence rate for Haemonchus contortus (58.00%) was higher than Trichostrongylus axie (16.00%). In this study, prevalence of abomasal nematodes in relation to age, sex, breed and nutritional status of the goats were also observed. There was no statistically significant difference observed the risk factor sex in relation to the prevalence of abomasal nematodes. However, there was statistically significant difference (p < .001) observed among the risk factors (age, breed and nutritional status) in relation to the prevalence and worm count of two abomasal nematodes. In general, a high infection rate with abomasal nematodes was observed in goats during the study period. Findings suggested that higher worm burden per animal found in Haemochus contortus (6.02±0.0928) and lower in Trichostrongylus axie (0.04±0.14). From this study it was concluded that Haemochus contortus is more susceptible for geo-climatic condition in research area.

End Date: 00-04-2010

Program Area: Animal Health and Management

Commodity: Goat

Objectives:

This study was undertaken with the objectives to determine the prevalence and load of abomasal nematodes in goats slaughtered in Thakurgaon district, and to determine the relationship between the risk factors like age, sex, breed and nutritional status and the prevalence and to look at the burden (intensity) of abomasal nematodes in goats.

Methodology:

Study area: The research work was conducted in Thakurgaon district from November 2009 to April 2010. A total of 31 abattoirs were selected randomly in the urban areas of Thakurgaon district. Most of the abattoirs were made by aluminum tin with concrete floor and some were mud-spattered floor. Study animals and sampling method: The study was conducted on goats slaughtered in 31 abattoirs in the urban areas of Thakurgaon district. A total of 250 abomasums from slaughtered goats were examined. Most of the samples were obtained from different abattoirs and it was difficult to trace the exact origin of the animals. The age of the animal was estimated by examination of the teeth and separated into two age group like young (≤ 20 months) and adult (≥ 20 months) for abomasal sample. In order to undertake the postmortem examination, the abomasums were legated with string and collect. Worm recovery: The laboratory work was done at parasitiology laboratory of the Department of Parasitology, Bangladesh Agricultural University, Mymensingh. The parasitic collections of the abomasal contents and washings were made after the method adopted by authors. Detailed morphological features of the parasites and eggs were studied after they were cleared in order to identify the species. Preliminary morphological studies of the parasites were made in living conditions taking representative samples from each collection. Species identification: The worms which were preserved in 10% formalin were poured in to petridishes and examined under a stereomicroscope. Identification was made using keys developed by [12] and [13]. Data analysis: Statistical analyses were carried out with Statistical Package for Social Sciences (SPSS) using F test. Odds ratio was calculated by standard formula.

Achievement/Findings:

Nematodiosis is one of the major obstacles to livestock productivity in Bangladesh. Its occurrence is mainly associated with the poor management system, lack of disease resistance breed selection and development of drug resistance of the parasite. Observation from the present study conducted on abomasal nematodes in goats, and goats slaughtered in different abattoirs showed that nematode in goats is the most prevalent disease in the area affecting the health of the animals. The species of parasites identified were Haemonchus contortus and Trichostrongylus axie. Therefore, significant economical losses in production are expected to occur in the study area.
