Abstract/ Executive Summary:

The mortality of goats is one of the major problems confronting goat husbandry in this country. The present study was undertaken with the aim to investigate the mortality of goats of various etiologies at nuclear breeding flock. A total of 114 goats of both sexes and of different ages were examined during this study period. Suspected cases of mortality were confirmed by clinical findings before death, postmortem findings and histopathological examination. Mortality rate was higher in group-3 age group (37.5%), than group-1 (34.37%) and group-3 (28.12%). Season wise incidence of mortality was highest in season-3 (46.87%) followed by season-2 (31.25%) and season-1 (21.87%). The causes of mortality were bloat (15.62%), diarrhoea (18.75%), pneumonia (21.87%) enterotoxaemia (12.5%), Fascioliasis (12.5%), Hydatid diseases (6.25%), colibacillosis (6.25%) and urinary problem (6.25%). Indeed the incidence of the diseases mortality in goat of this farm could be reduced to a substantial rate by improving the management system currently practicing in the farm.

Start Date: 00-10-2007

End Date: 00-10-2008

Program Area: Animal Health and Management

Commodity: Goat, Diseases

Objectives:

The present study was aimed to investigate the incidence of different diseases of goat in that biosecured farm, to explore the cause of mortality of goat in different age, sex and seasons, through examining the clinical pathology of diseases and to study the morphological lesions (gross and microscopic) of the organs arising from different diseases.

Methodology:

A total number of 114 goat population of different age groups and sexes were examined during the period of October, 2007 to October, 2008 in this nuclear breeding flock of Black Bengal Goat.

Clinical pathology To aid in diagnosis of different diseases blood examination, feces examination and skin scraping was done. All protocol obtained from Coles E. H. (1986).

Pathological Study: Dead animals were examined through necropsy (gross) and histopathological study. During the postmortem examination the suspected samples were collected and fixed in 10% neutral buffered formalin. After fixation the tissues were processed, sectioned and stained as per standard procedure (Luna, 1968). Photomicrography was taken at the Department of Pathology using photomicrographic camera (Olympus PM-C 35 Model).

Achievement/Findings:

This study recorded higher rate of mortality in female animals due to various diseases. The reasons of more susceptibility of female animals to different diseases are not always clear. However, it may be mentioned that special care and improved feeds were given to the male goats as they were used for semen collection. Under the circumstances, the well nourished male animals may be less susceptive to the daage of pathogenic agents. Moreover hormonal effects could be another factor which cause more susceptible to diseases in female animal than male.
