Abstract/ Executive Summary:

The myiasis is very common surgical affections of ruminants in Bangladesh. There are limited researches on the maggot wound infestation in Bangladesh. A retrospective study was performed to collect data and to get a clear and genuine concept on myiasis affections in ruminants in respect to species. age, sex, breed, season and predilection sites. The present study was conducted in Veterinary Clinic, Bangladesh Agricultural University, Mymensingh and data was recorded from 2008 to 2012. Results showed that 151 animals were affected with myiasis and maggot wounds predominantly occurred in the cattle (71.6%) among which calves were more affected. Myiasis was very prone to occur in the navel, vulva, leg and ear. During the study period, more affection occurred in animals of below 6 months (41%). The females (66%) were more frequently affected than the males (34%) and cross breed (57%) was more affected compared to local breed (43%).Moreover, infestation frequently observed from March to June (80%). This study could help veterinarians as well as farmers to be aware of the occurrence of maggot wounds and to implement protective measures with minimum complications.

Keywords: Retrospective study, Myiasis, Ruminants

Location: Veterinary Clinic, Bangladesh Agricultural University, Mymensingh.

Start Date: 00-00-2008

End Date: 00-12-2012

Program Area: Animal Health and Management

Commodity: Diseases

Objectives:

To observe the occurrence of myiasis based on species, age, sex, breed, season and predilection sites in ruminants brought to Veterinary clinic

Methodology:

The study was conducted at Veterinary Clinic, Bangladesh Agricultural University, Mymensingh. Clinical data on maggot infestation in cattle and goat presented to Vet clinics from 2008 to December 2012, were recorded and analyzed to investigate the occurrence of myiasis with respect to species, age, sex, breed, season and predilection site. All animals were allotted into three groups according of ages i.e. <6 months, 6 months to 2 years and >2 years. Moreover, data were categorized as male and female according to sex. To consider the relation between breed and affection of maggot, data were also categorized as local and cross. To study the relationship between maggot infestation and time of the year as season data were distributed into three parts, i.e. March to June, July to October and November to February. Descriptive statistical analysis was performed to get results and all data presented as percentage.

Achievement/Findings:

The infestation results in emaciation, malaise, and reduces fitness and efficiency of animals. Some of the wounds become so severe that euthanasia may be recommended. Wounds or any breach in the continuation in the skin may result in maggot infestation. Indeed, removal of the larvae allows more rapid healing. With respect to prevention, veterinarians and farmers should be aware about the effectiveness of treating all skin wounds. Preventive measures should be undertaken to minimize losses from myiasis. Dissemination of these findings among the farmers may prevent maggot infestation and control the spread of myiasis.
