Abstract
The objective of this study was to determine the prevalence and factors affecting Anaplasma marginale infection of goat farming in Chonburi province, Thailand. A total of 182 samples were collected from clinical services records from the Veterinary Teaching Hospital, Rajamangala University of Technology Tawan-ok. Moreover, the potential risk factors of A. marginale infection, including vectors infestation, barn-types, preventive medicine protocols using vector-control agents and/or deworming programs, and the farming areas were statistically analyzed. The results revealed that 24.7% of goats were positive for A. marginale infection. The Nhong Yai district had the highest infection rate at 34.1% (15/44). The Mueng, Chonburi and Sri Racha district goats were infected at the rate of 27.5% (11/40) and 24.3% (9/37), respectively. The potential significant factors affecting A. marginale infection were vectors infestation (P < 0.01) and preventive medicine protocols using vector-control agents and/or deworming programs (P < 0.05). In conclusion, the vectors infestation increases the chance of A. marginale infection. Conversely, appropriate consistent preventive medical health management by application of vector-control agents and/or deworming programs can reduce the likelihood of infection. Our study could serve as a guideline for prevention planning and for further study of livestock rearing behavior concerning infection of blood parasites in nearby areas
Highlights
Goat farming in Thailand has been increasing during the last decades
The Department of Livestock Division (DLD), Thailand reported that the amount of goat production in Chonburi province had increased to at least 2,000 animals in 2012, most of which were goats produced for meat
For univariable analysis, the chi-square test was performed to determine the relationship between A. marginale infection and the relevant risk factors
Summary
Goat farming in Thailand has been increasing during the last decades. The Department of Livestock Division (DLD), Thailand reported that the amount of goat production in Chonburi province had increased to at least 2,000 animals in 2012, most of which were goats produced for meat. The Chonburi Provincial Livestock office reported that the number of farm-raised goats and sheep had reached 2,500 animals by 2014 and gradually increased to more than 6,000 animals by 2019 (DLD, 2020b). Data from the Veterinary Research and Development Center, Eastern Region (VRD-EP) in 2020 demonstrated that the goat population in Chonburi was gaunt, anemic and some had died, the main cause of which was infestation from external - internal parasites or blood protozoa infection (DLD, 2020a)
