Mastering bovine reproduction: the strategic importance of postpartum management

Calving is a key stage in a cow's life. This period of intense physiological change for dairy cows is comparable to the start of a marathon, the outcome of which determines the profitability of the farm. Even when calving proceeds normally, up to 90% of animals suffer inevitable bacterial contamination, leading to changes in the uterine microbiota and local inflammation. Proactive management of this critical phase (21 days postpartum), specifically targeting uterine involution and eubiosis of the uterine environment (such as bacterial balance), is therefore essential to prevent delayed cyclicity and ensure the future performance of the herd.

The zootechnical impact of this health management approach has been validated by numerous field trials conducted over more than 15 years. Administration of the bolus after calving results in a tangible improvement in the condition of the reproductive system, with a 130% increase in healthy cervical mucosa and a 20% increase in well-involuted uteri 30 days post-calving. These physiological indicators lead to superior reproductive results. The success rate at first insemination (AI1) or success at mating is increased by 11%. There is also an increase in milk production of approximately 1 kg per day over the first 60 days of lactation.
