Prevalence of Eimeria infection in goats in Ben Tre province and the treatment efficacy of some drugs in treatment
The study was conducted in 2 districts, Mo Cay Nam and Mo Cay Bac, in Ben Tre province from January 10, 2023, to September 15, 2023, to identify Eimeria infection in goats and make a choice of effective drugs. A total of 420 goats were in several stages of age, including less than 4 months old, from 4 to 12 months old, and more than 12 months old. The results showed that two survey districts were infected with Eimeria spp., with an overall infection rate of around 73.8%. Mo Cay Nam and Mo Cay Bac accounted for 71.4% and 76.2%, respectively. The infection rate decreased gradually with age: less than 4 months old (98.6%), peaking at 4-12 months old (81.4%), and more than 12 months old (41.4%). The coccidiosis intensity ranged from 1 (+) to 3 (+) in all goats, with the highest rate observed in severe intensity (3+). Five coccidia oocyst species with gradually decreased frequency, such as Eimeria ninakohlyakimovae (66.7%), Eimeria arloingi (58.6%), Eimeria hirci (39.8%), Eimeria christensen (29.3%), and Eimeria alijevi (10.2%). Watery feces had a greater rate of coccidia oocyst infection (96.7%) than solid feces (51.0%). Coccidial oocysts were found in goats of all ages, however goats infected with two types of coccidioid oocysts per faeces sample accounted for a high rate (45.5%). The treatment of goats afflicted with coccidiosis with two medications, Amprolium and Sulfachlopyrydazine, was completely successful. Neither medicine had any adverse effects during the testing.
