Abstract/ Executive Summary:

The objective of this study was to investigate the incidence of different diseases in a bio-secured goat farm at the Bangladesh Agricultural University campus, Mymensingh. The diseases were recorded mainly on the basis of history, clinical signs, and examination of organisms. Higher incidence (%) of diseases was found for diarrhea 17.4 followed by fever and anorexia (16.5), pneumonia (13.8), bloat (10.6), contagious ecthyma (8.3), and mixed parasitic infestation (7.0). Incidence of diseases had higher in adults (>1year) 40.0% than young goats (7-12months) 31.7% and kids (<6 months) 28.4, respectively. Higher incidences of diseases were found in the rainy season (49.6%) and then winter (30.4%) and dry period (19.6%). The higher incidence of diseases in intensive rearing systems is possibly due to increased stresses on animals, to which they responded by higher diseases incidence. Moreover, these animals were purchased from the farmer level where they have a lack of knowledge for preventive health care. This group of animals may act as carriers of many diseases and it might be the cause of a higher incidence of diseases.

End Date: 00-10-2018

Program Area: Animal Health and Management

Commodity: Goat, Diseases

Objectives:

1. To investigate the incidence of different diseases of goats in that bio-secure farm,

2. To explore the diseases in different ages, sex and seasons,

3. To examine the clinical pathology of diseases, and

4. To study the morphological lesions (gross and microscopic) of the organs arising from different diseases.

Methodology:

In order to investigate the incidence of various diseases of goat, a total number of 114 goat populations 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. The percent of the incidence of different diseases was calculated on the basis of animals suffered out of a total number of diseased animals. The following materials were used and methods were followed in this experiment. Out of 114, there were 72 female and 42 male goats of different ages on the farm. All animals were neckband tagged to maintain individual identity. A separate data sheet for each animal was maintained for recording data. The influence of the age of goat, sex, and seasonal variation on the incidence of diseases was studied by dividing the infected goat into three age groups (Group-1 up to 6 months, Group-2 above 6 to 12 months, Group-3 above 12 months) and also seasonal variation by dividing Season-1(March-June) dry period and Season-2 (July-October) rainy season and Season-3 (November-February) winter. On this farm, the biosecurity procedures are strictly maintained. The farm also maintained the health management program (medication and treatment, vaccination and parasite control program) dipping, a supplement of good nutrition and feeding management, and predator control. The bio-security was maintained as per routine procedure to maintain the farm to reduce the incidence of diseases. Supplement of good nutrition and feed was ensured here. The does and bucks are fed with Napier and/or German grass twice daily as per requirement. The feed was supplemented with commercial concentrate (crude protein content: 120g/kg DM and energy content: 10.4 MJ ME/kg DM) in the morning and again in the afternoon at the rate of 200gm/ buck and a concentrated mixture (45% wheat bran, 20% khesari bran. 20% Soyameal, 10% maize crushed, 2% protein concentrate, 1.5% salt, DCP 1.5%, and 0.1% vitamin-mineral premix) was provided twice daily in the morning and evening at the rate of 100gm/ doe. Clean and safe water was being made available at all times. All does and bucks were vaccinated and deworming and dipping were also performed routinely on this farm. A regular vaccination schedule was maintained in this farm against Peste des Petits Ruminants (PPR). Vaccinations were performed that were not affected with diseases and pregnancy. The farm was visited regularly and the sick animal was identified through history and clinical examination. The history of the diseases including treatment and vaccination and clinical examination of affected animals were recorded on the basis of clinical signs such as weight loss, abortion, diarrhea, hard udder, arthritis, pneumonia, or neurological symptoms. To aid in the diagnosis of different diseases blood examination, feces examination, and a skin scraping were done. All protocols were obtained from Coles EH.

Achievement/Findings:

The present study was conducted on a relatively biosecure farm. The incidence of diseases in this farm was higher than in other studied as these animals were purchased from farmer level (where they have a lack of knowledge for preventive health care). However, the incidence of the diseases in goats of this farm could be reduced to a substantial rate by improving the management system currently practiced on the farm.
