Survey on the situation of reproductive tract inflammation of sow after delivery and efficacy of antibiotic treatment

Abstract

The result of testing exudate from 143 sows after delivery showed that there were 106 sows suspected to inflame the genital tract, accounting for 74.13%. Of which, there were 100 samples infected with E.coli, Streptococcus, Staphylococcus, Pseudomonas with the rate of 75.47%, 45.28%, 47.17% and 18.87% respectively. In order to select the suitable antibiotics for treatment of this disease, the Kirby-Bauer (1966) disk diffusion susceptibility test protocol was applied and the tested result showed that most of the isolated bacteria were susceptible with doxycycline and florfenicol. Then, 3 experimental treatment formulae, such as: Formula 1 (Marflo-45%, Cloprostenol and Gluco-K-C-Namin); Formula 2 (Doksilin-LA, Cloprostenol and Gluco-K-C-Namin) and formula 3 (Floxy, Cloprostenol and Gluco-K-C-Namin) were conducted to determine the efficacy of the candidate antibiotics. The treatment result indicated that the efficacy of three treatment formulae was very high (100%) and not significantly different among them. However, the duration of treatment was longer for formula 2 (approximately 6 days) compared to formula 1 and 3 (approximately 4 days). The experimental treatment result also showed that the ability of recovering reproductive function of the sows in three treatment formulae was the same (the oestrus and pregnancy rate was 100%).
