How does poor body condition affect anoestrus in cattle?

Answer 1

Poor body condition (on a scale of 1 to 9, a BCS of 4 or less) will lengthen the anestrus period of that cow. In other words, she will take longer to come back into heat and thus be ready to breed if she were too thin than in normal body condition.

In general, poor body condition can cause anoestrus (anestrus in American English spelling). Anoestrus is an absence of the normal reproductive cycle typically associated with seasonal changes. However, a cow that does not have sufficient body reserves to support a pregnancy may go into anoestrus to prevent further strain on limited resources.
