Will cow eat her placenta?
Placentophagia, the act of eating placenta, is observed in many placental animals including cows. There is no single, definitive reason known for why cows eat their placenta but in searching for the answer we came across four main theories: bonding, hunger, predator avoidance, and instinct. After taking a closer look at the possible reasons why cows eat their placenta we contacted a number of producers, not only cattle but also swine, horse, and sheep producers to discuss what is done with the placenta on the farm and if placentophagia has ever caused any problems. The idea that a cow eats her placenta as a means of bonding with her calf can probably be rejected. The placenta is released a few minutes to a few hours after the calf is born and it is not usually in contact with the calf. The idea of bonding may have arisen from confusing amniotic fluid which the newborn calf is covered in with the placenta. "Most cows will pay attention to the calf while eating their placenta", says Murray Warnke, a beef cattle producer from Wetaskiwin, AB. "But some become focused on the placenta and ignore the calf." In these cases, removing the placenta causes the cow to return her attention to her calf. This, in conjunction with the fact that the placenta is generally not in contact with the calf, opposes the idea of bonding as a reason for cows to eat their placenta. The second theory, hunger, is divided into two categories: general and specific hunger. General hunger indicates that the cow is just plain hungry after calving. The fact that the placenta is edible, and generally in close proximity to the calf, makes it a convenient meal. Specific hunger refers to a craving. This theory suggests that there may be something in the placenta, for example nutrients or hormones, that the cow craves post-partum. When asked if he had ever encountered a problem as a result of a cow eating her placenta, Alberta dairy farmer, Alex Beattie, responded that he had never encountered any problems but "some people believe that eating the placenta relaxes the cow and is good for the cow". If we take into consideration the belief that placentophagia in humans helps prevent post-partum depression, placentophagia in cows may be beneficial to their psychological health and specific hunger may help them to obtain this benefit. The third and most popular theory for why cows eat their placenta is predator avoidance. Veterinarian Dr. Jennifer Dodd admits that it is not a definite reason but describes it as "a defensive mechanism to ensure that there is no evidence of the birthing in order to protect against predators." The idea is that the cow eats her placenta so that the smell does not attract predators towards her and her very vulnerable calf. The final theory concerning why cows eat their placenta, instinct, is mostly self-explanatory. They just do it, it's instinctive. Remember, cows were not always domesticated and it is a fact that virtually all placental mammals eat their placenta with the exception of camels, Cetaceans (an order of aquatic mammals including whales and dolphins), and Pinnipeds (an order of semi-aquatic mammals including seals and walruses). Cows eating their placenta are not unique among placental mammals
What will happen if the cow fed placenta?
Cows naturally eat the placenta after their calf is born. This is to deter predators from investigating the birthing site and possibly finding the cow's calf. It is something done by all ungulate mothers, both domesticated and wild.
