Abstract

Endometritis is a great barrier to the dairy production, as it diminishes fertility and causes economical losses with treatment costs and lowering production. This work has evaluated the value and the efficacy of the use of Cephapirin, Ceftiofur, and Oxitetracyclin for endometritis treatment. 120 animals were diagnosed with grade II and III endometrites trough hyteroscopic examination, and were allocated in four groups of 30 animals, control group (no treatment), Cephapin, that received i.u. Infusion of 500 mg of Cephapirin, Ceftiofur, received s.c. 6.6 mg/kg of Ceftiofur, and Oxitetracyclin, that got treated with i.u. Infusion of 4g of Oxitetracyclin. The animals were evaluated for four times or until they reached cure. Body condition score, Uterine involution assessed by ultrasound measurement of cervix and uterine horns, presence and the characteristic of uterine content, uterine hemodynamic patterns, cytology response, and uterine health response to treatment assessed by hysteroscopy were evaluated at each examination. Cows treated with Cephapirin and Ceftiofur presented a drop on the proportion of PMN retrieved at endometrial cytology examination (P = 0,028). All the treatments presented a bigger rate of cure than control group, at least 23% higher (P = 0,042); however, there was no difference among treatments. There was no difference on cure time among treatments. In conclusion, treating endometritis is an advisable conduct. All the treatments tested in this trial were equally efficient (AU)
