Abstract

The objective of this study was to quantify the effect of some postpartum uterine affection on productive and reproductive performance of high yielding Holstein cows. Productive, reproductive and uterine affections data were obtained from high yielding Holstein herd within private dairy enterprise. Throughout the studying about 705 dairy records were enrolled in a randomized trial. Data of BCS, parity, calving season, milk yield (initial, peak, and 305 milk yields) and reproductive parameters (days to first estrus, days open, service per conception, intervals between heats, calving interval and pregnancy rate at 100 post last insemination) were obtained from on-farm record system (DairyComp 305). Retained placenta, puerperal metritis and mixed cases (retained placenta and puerperal metritis) were diagnosed by herd veterinarians. The treatments of such affected cases were done according to standards of herd treatment strategy. Dairy cow were grouped according to their uterine affection into 4 groups, as puerperal metritis, retained placenta, mixed cases and healthy. The results of this study revealed that: Early postpartum uterine problems affect dairy cattle productive and reproductive performance so badly, as puerperal metritis and retained placenta had worst effects on milk production and these bad effects maximized when the retained placenta developed together with metritis within the same case. Dairy cattle reproduction goes in the same way of production as the reproduction affected badly with puerperal metritis, retained placenta, and mixed cases. Early postpartum uterine affection increased days to first estrus, days open, service per conception, calving interval, and decreased pregnancy rate in the first 100 DIM.
