[Methods of treating puerperal endometritis in cows].

Tested were two methods for the treatment of cows affected with acute endometritis after giving birth. The experiments were carried out with a total of 92 cows of the Bulgarian Brown breed kept under equal condtions of feeding and management. Two tests and one control groups were formed. The first group of cows (48) were treated with a bilateral epipleural block after Mossin. As a result 66.7 per cent of the cows conceived up to the 80th day after calving and 43.7 per cent at the first insemination. The service period of the impregnated cows of this group was 73.3 +/- 4.94 days, on an average. The second group of cows (25) were treated muscularly with a combination of 1 per cent magnesium sulphuricum solution (40 cu. cm), vitamin C (10 cu. cum), norsulphasol (5 g), and chloramphenicol (2 g). The treatment was repeated at a three-day interval. The results of the treatment accounted for 68 per cent impregnated cows up to an 80-day service period, and 48 per cent--at first insemination. The service period of the cows of this group lasted 69.3 +/- 6.0 days, on an average. The control group cows were treated at random with penicillin and streptomycin, muscularly. The conception rate at first insemination was 36.7 per cent, and within the range of an 80-day service period--47.02 per cent of the treated cows. The average service period for this group lasted 91.80 +/- 9.28 days.
