[Effect of certain procedures on the puerperal period in cows].

The course and duration of the post delivery period, uterine involution, independence and service period, number of fertilizations and the percentage of complications were studied in 82 cows aged 3 to 7 years, reared by two differing technoligies. One group (experimental) of 53 cows was reared together with the calves until the 6th day post delivery, while the other group (control) of 29 cows was reared without the calves. Both groups were subdivided into groups with and without complications; It was established that the proposed technology of cow rearing with the calves sucking until the 6th day post delivery creates good conditions for the course of puerperium. Clinically uterine involution lasts 27.5 +/- 0.88 days, the independence period lasts 95.8 +/- 5.94 days, the service period -- 115.9 +/- 4.28 days, and the fertilization index is 1.26 +/- 0.21. The proposed technology of cow rearing letting the calves suck until the 6th day post delivery can be applied in animal rearing practice.
