Cows eat afterbirth as a means of protection for the newborn calf. The strong smell of the afterbirth attracts predators that can harm the calf. The newborn calf is very weak and vulnerable, and the presence of such predators can be deadly.

Placenta provides protection for the fetus
The placenta in cows provides protection for the fetus during pregnancy and after delivery. The placenta consists of six layers. Three of these layers are maternal, and three are fetal. One type of placenta is epitheliochorial, and forms a barrier between the maternal blood and the fetus’ blood. Its purpose is to protect the fetus by preventing the passage of bacteria and viruses.
The placenta passes oxygen to the fetus and transports waste products from the fetus to the mother’s blood. It also produces hormones that are needed during pregnancy. It may develop low in the uterus at the beginning of pregnancy, but it will usually move higher as the uterus stretches and the fetus develops. The position of the placenta is usually checked at the 18-week ultrasound.
Immunizations prevent retention of the placenta
While milk is produced by cows, it is not the only source of maternal antibodies. Antibodies are also transferred to young animals through colostrum. The amount of transfer depends on the placentation stage and species. In cows, the epitheliochorial placenta abuts the uterine epithelium and chorion.
Immunizations are important to reducing the risk of retained placenta in cows. Immunizations help protect cows from various pathogens that can cause retention of the placenta. These vaccinations prevent the formation of bacterial complication caused by retained placenta. In addition, management of cows affected by retained placenta can optimize peripartum immune function and encourage feed intake during the transition period.
The timing of routinely administered vaccines during pregnancy has been determined through current clinical guidelines. Influenza vaccination is given in all three trimesters. The Tdap vaccine is administered late in the second or early third trimester of pregnancy to improve transplacental transfer.
Unhygienic calving conditions
Cows eat their placenta after birth because it contains nutrients they lost during the labor and birth. The fresh smell of blood and fluid can attract predators. Also, a new calf smells sweet and the mother has to take care of it. However, there are certain steps to prevent cows from eating afterbirth.
The first step in preventing cows from eating their own afterbirth is to ensure that calving takes place in a clean, hygienic environment. Most calvings did not occur in maternity units, and producers often left heifers unsupervised for long periods of time. The second stage of labour should be monitored and intervention should be sought if it takes more than two hours. In some countries, tocolytic agents can be used to postpone calving and manage dystocia, but they are not available in every jurisdiction. Moreover, calving alarms can be installed to alert a herd to the imminent calving time. The biosensors can monitor the intravaginal temperature, reticular temperature, and vaginal mucus electrical resistance to detect an impending
Placenta is a food for animals after calving
The placenta is a food for animals, including humans. It’s an important part of a cow’s diet after calving, as it helps the cow protect itself. The sweet smell of the new calf attracts predators, so it’s important for the cow to get rid of that evidence. Also, the placenta is full of nutrients and hormones that help the cow recover internally.
While the placenta is a food for animals, there are many risks associated with handling it. One major risk is Brucellosis, a disease that is transmitted to humans and other animals through the placenta. Keeping the cows out of dirty environments and in pasture is the best option for protecting the placenta.
Effects of antibiotics on retained placenta
Retained placenta after birth in dairy cows can be treated conservatively with antibiotics. The placenta should not be clinically symptomatic, be down in the milk or have a foul odor in the fluid discharge from the uterus. Although antibiotics can be used for retained placenta after birth, there are several disadvantages. These antibiotics can delay uterine involution, cause metritis, and increase the risk of pyometra in treated cows.
Firstly, the placenta can become infected with Brucellosis, a disease transmitted to humans and other animals. Consequently, it is important to prevent transmission of this disease. If you suspect that your cow has retained placenta, contact your veterinarian as soon as possible. There are several treatment options available, but the two most common are manual removal and systemic antibiotics.
