The study of some characteristics of Eimeria infection in goats in Tra Vinh province and the efficacy of some drugs in treatment
The study was conducted in Duyen Hai district, Chau Thanh district and Duyen Hai town in Tra Vinh province from August 2023 to February 2024. The purpose of this study was to identify Eimeria infections in goats and to develop an effective drug selection method. The Willis and McMaster swelling method was used to test 450 goat fecal samples. The results showed that survey areas were infected with Eimeria spp., with an overall infection rate of 61.33%. Duyen Hai district, Chau Thanh district and Duyen Hai town had goats infected with coccidiosis at rate 60.0%, 62.67% and 61.33%, respectively. The infection rate decreased gradually with age: less than 4 months at 77.3%, peaking at 4-12 months at 65.3%, and more than 12 months at 41.3%. Infection was found in all three goat breeds surveyed: 61.3% in Bach Thao goats, 59.3% in Boer goats, and 63.3% in cross goats (Boer x Bach Thao). Male goats had infection rate (60.4%) and female goats (62.2%). Goats raised in poor veterinary hygiene environments had infection rate (93.3%) and goats raised in appropriate veterinary hygiene conditions (29.3%). Goats were infected with 2-3 species/fecal sample (49.9%) and infected with more than three species/feces samples (22.5%). Goats were infected with five species of coccidial oocysts including E. ninakohlyakimovae (60.7%), E. hirci (50.2%), E. arloingi (37.1%), E. christensen (7.1%), and E. alijevi (4.4%). Amprolium at a dose of 1 g/60 kg body weight/day, given to goats for five consecutive days, and toltrazuril 5% at a dose of 1 ml/goat, given to goats as a single dose, provides effective treatment of coccidiosis in goats with good results. Both the drugs were safe throughout the experiment.
