Abstract/ Executive Summary:

The study was conducted at Upazila Livestock Office, Sadar, Dinajpur of Bangladesh from January 2018 to December 2018 to investigate the incidence of reproductive disorders in goat. Data on reproductive disorders were collected on the basis of owner’s complain and observed clinical signs. Age and season wise occurrences of reproductive disorders were also recorded. Descriptive statistical analysis was done. Out of 2484 clinical cases, a total of 107 reproductive disorders of goat were recorded. Incidence of abortion (38.3%) was higher and pyometra (0.9%) was lower among reproductive disorder in goat. The incidence of reproductive disorders of goat was higher in group-2 (above 1-2 years) (36.4%) followed by group-1 (upto 1 year) (21.6%), group-3 (above 23 years) (21.5%), group-5 (above 4 years) (15.3%) and group-4 (above 3-4 years) (3.6%). Among reproductive disorders, the incidence of abortion was higher in group-2 (58.9%) followed by retained placenta (50%) in group-4, metritis (47%) and dystocia (23.5%) in group-5, repeat breeding (17.4%) and anestrus (4.3%) in group-3, and pyometra (2.5%) in group-2. Slight seasonal variation among the individual case of reproductive disorders were recorded, highest in winter (34.5%) than summer (32.4%) and rainy season (31.7%). The incidence rate of abortion was high in each season (summer 25%, rainy 32.3% and winter 56.7%). In case of retained placenta and dystocia, the incidence was high in summer season (22.2%). But in case of metritis and repeat breeding, the incidence was high in rainy season (32.3% and 14.7% respectively). For treatment of reproductive disorders in goat, antibiotics drugs (35%) were used most commonly and hormonal drugs (3%) used in lower percentages. It was concluded that the most pressing constraint on goat reproduction in Bangladesh is abortion, retained placenta, dystocia and metritis. Strategies should be taken to minimize their occurrence.

Program Area: Animal Health and Management

Commodity: Goat

Objectives:

To determine the incidence of major reproductive disorders, causal factors along with different therapeutic drugs used in goats.

Methodology:

The study was conducted at Upazila Livestock Office, Dinajpur Sadar, Dinajpur under the supervision of Department of Medicine, Surgery and Obstetrics. The study was conducted for a period of one year from January, 2018 to December, 2018. All the sick animals brought for treatment to the Upazila Livestock Office were used for this study. The total number of clinical cases of goats were 2484 among them the reproductive disorders of goats were 107. In order to investigate the incidence of reproductive disorders in goat, a total number of 107 goats were examined on the basis of owner’s complaint and observed clinical findings. The influence of the age of goat, and seasonal variation on the incidence of diseases was studied by dividing the infected goat into five age groups (Group-1 up to 1 year, Group-2 above 1 to 2 years, Group-3 above 2 to 3 years, Group-4 above 3 to 4 years, Group-5 (above 4 years) and also seasonal variation by dividing Season-1 (March-June) summer season and Season-2 (July-October) rainy season and Season-3 (November-February) winter season. For collection of data, direct interview of owner attended to the Upazila Livestock Office, Dinajpur Sadar, Dinajpur daily from 9.00 am to 4.00 pm by using questionnaire method was used. Information given by the owners was recorded on the questionnaire. The questionnaire was prepared considering to the objectives of the study, and was designed in such a way that the farmers can understand easily. After taking history from owner individual goat was examined and diagnosed the reproductive disorders. Body condition score (BCS), behavior, posture, gait, superficial skin, salivation, nasal discharge, locomotive disturbance was observed by distant visual examination of the patients. Examination of different external parts of the body of each animal were done clinically brought at Upazila Livestock Office by using various close observation techniques. The animals were clinically examined at a veterinary hospital and temperature, pulse and respiratory rate from each of the animals were recorded. The presented clinical manifestations of various goat were recorded and the farmer’s complaints in relation to the disease were recorded carefully. Clinical Findings from each of the animals were observed and recorded. The reproductive disorders were diagnosed by clinical findings, physical examination and history of the disease. Disease incidence was calculated by using following formula: Incidence ( %) = {(No. of affected goat with reproductive disorders) / (Total clinical cases in goat)} x 100. The data were recorded and analyzed statistically by using software “SPSS” (version 17). One-way ANOVA were performed and the results were expressed in percentage with P value and significance was determined (P<0.05).

Achievement/Findings:

Overall incidence of reproductive disorders was 12.29%. The major reproductive disorders in goat were recorded abortion (38.3%), metritis (23.4%), dystocia (15.8%), retained placenta (10.3%), repeat breeding (9.3%), anestrus (1.8%) and pyometra (0.9%). The reproductive disorders were higher in 2-3 years age than other groups. Though there is no significant seasonal variation on the incidence of reproductive disorders in goat, therefore, abortion was high in winter season (56.7%) whereas metritis was high in rainy season (32.3%). In summer season, the dystocia and retained placenta were high. The most pressing constraint on goat reproduction is abortion, metritis and dystocia. Strategies should be taken to minimize their occurrence.
