What does it look like? the course of childbirth in a cow – from the first signals to the beginning of labor

The course of childbirth in a cow It begins with the preparatory phase, which usually lasts from several hours to as long as a day. During this time, the cow's body prepares for calving under the influence of hormonal changes, and an attentive farmer can notice the first clear signals. The animal becomes restless, stands up and lies down more often than usual, looks at its sides, shifts from one foot to the other, and sometimes separates from the herd and seeks a quiet place. Physical symptoms are also typical: visible swelling of the vulva, its redness, loosening of the pelvic ligaments at the base of the tail, and the appearance of stringy, clear, or slightly cloudy mucus. In many cows, the udder also enlarges earlier and becomes severely toned. This is a time when regular monitoring is particularly important, as properly assessed signs can distinguish the natural onset of labor from a situation requiring a more rapid response. Properly preparing a clean, dry, and quiet environment reduces stress, reduces the risk of infection, and increases the safety of both the cow and the calf. In practice consistent with modern peri-calving prevention, supporting the cow's condition before and after calving is also crucial, including appropriate nutrition and supplements to support the peri-calving period.

The most important stages of calving in a cow - what happens during calving

The course of childbirth in a cow It is divided into three main phases. The first is the period of cervical dilation, which typically lasts 2 to 6 hours, although in primiparous cows it can extend to 8–12 hours. The cow becomes restless, stands and lies down more frequently, looks at her belly, lifts her tail, may eat less, and mucus appears from the genital tract. These are normal signs of the body preparing for labor. During this time, contractions are still weaker but gradually intensify, preparing the genital tract for the passage of the calf.

The second phase involves the actual pushing and expulsion of the fetus. It typically lasts from 30 minutes to 2 hours, and in older cows it can be shorter than in heifers. Normally, the amniotic sac is visible first, followed by the calf's forefeet and head. This pattern is considered normal. Strong, regular contractions and the calf's progressive emergence indicate a normal course. A farmer should be alert if there is no progress for 30–60 minutes of strong pushing, the appearance of only one limb, only the head, or a rearward position without rapid progress. In such situations, the course of childbirth in a cow may require the help of an experienced person or veterinarian.

The third phase is the expulsion of the placenta, usually within 2–8 hours after calving. A longer period is acceptable, but retention of the placenta beyond 12 hours requires observation, and after 24 hours, veterinary consultation. After calving, it is important to assess the cow's condition, water and feed intake, and provide prompt support during the post-calving period. In breeding practice, not only the placenta itself is important. the course of childbirth in a cow, but also appropriate care after calving, reducing the risk of weakness, metabolic disorders and regeneration problems.

Alarming symptoms during calving – when you need to act quickly

Although the course of childbirth in a cow Often, it goes without any major problems; there are situations that require immediate action. A prolonged lack of progress in labor is especially alarming: if, after the water breaks, there is no visible movement of the calf for 1-2 hours, and the contractions weaken or stop, the risk of complications increases rapidly. Symptoms such as severe weakness of the cow, lack of strength to push, rapid breathing, apathy, or signs of pain should also raise concern. This can be particularly dangerous. incorrect positioning of the calf – only one limb visible, head tucked under, breech presentation, or a mismatch between the size of the fetus and the birth canal. In such cases, help should not be delayed because of the prolonged cow giving birth increases the risk of calf hypoxia and maternal injuries. Urgent veterinary consultation is also required if there is heavy bleeding, suspected uterine torsion, uterine prolapse, or retained placenta longer than 12 hours after calving. Post-calving care is also very important: a clean and dry place, hygiene of the vulva and udder areas, and rapid replenishment of energy and fluids. In practice, appropriate calving support and preparations for dairy cows, such as the solutions offered by ruminta.eu, including products supporting energy management, reducing metabolic problems and the condition of the cow after giving birth.
