“…4 Several controlled field studies are consistent in showing that management for first insemination based primarily on automated activity monitoring (AAM) versus timed AI (TAI) result, on average, in similar proportions of cows pregnant by end of the treatment period (75 to 85 DIM) 4,7,9 and through the whole lactation. 4,7,10,14,15,16 There are several important considerations that emerge from these studies:…”

“…Cows with elevated serum haptoglobin at 2 DIM or greater blood concentration of BHB at 15 DIM were also less likely to be detected in estrus. Several recent studies 10,11,15,23 indicate that estrus detected before the end of the VWP (~50 DIM), especially > 1 estrus and more intense estrus, 23 is favorable for both detection of estrus by AAM for first AI and success of that breeding. Early estrus detection may be a practical, simple means to summarize a cow's reproductive status, including recovery from postpartum disorders, and therefore a useful marker of the likelihood of expression of fertile estrus.…”

Sensor-based management is growing rapidly in dairy farming. Activity, behavior and rumination monitors and data from automated milking systems and calf feeders are established management tools and hold promise for earlier or more efficient detection of health problems. However, gaps remain in validation and especially in turning streams of data into actionable information. On average, dairy herds can achieve comparable reproductive performance with management emphasizing estrus detection by activity monitors or timed insemination programs, but herd-specific variables will affect relative performance. Sensor-based screening of fresh cows may be useful to save labor or reduce disruptions to cows’ routines, but more validation is needed before this can augment or offset skilled, rational detection of health problems.

The article presents the reproductive quality indicators of the Holstein herd of APA (C) “Kuzminsky” (Moscow region) with different milk productivity levels. Some patterns have been identified for the herd, reflecting associations between reproductive and productive traits. The coefficient of the reproductive capacity ranges in the herd from 0.976 to 0.986, and the highest average rate was noted among cows with the highest milk yields in the herd. It’s noteworthy that the largest group (n=100) with an average level of milk yield per herd was characterized by the lowest coefficient. The average calving interval is 372 days, which can be explained by an extended service period; the dry period duration in cows with high milk yields is the maximum among the studied livestock.
