My cow ate placenta. Is it true milk yield will drop as vets say?

Updated On September 23rd, 2025

Our Cow has eaten its placenta. I have consulted nearby veterinarians, they all are saying that your cow will soon stop or minimise milk yield because this placenta affects milk yield. Is it true or not?

Hello. As I said earlier, this is perfectly normal behavior for all mammals, including cows. Unless this was a diseased placenta, this will not affect milk yield. As a matter of fact, eating the placenta can INCREASE milk yield. Cows may become slightly calcium deficient during pregnancy & the placenta is a calcium dense tissue. Cows do not digest this tissue well, so the placenta actually serves as a slow release calcium supplement to her. This is a great benefit to the cow & her milk yield.
