Question 1 Report

Which of the following will not help milk let-down in a lactating dairy cow?
Answer Details
The option that will not help milk let-down in a lactating dairy cow is the injection of progesterone. Progesterone is a hormone that is primarily involved in the preparation and maintenance of pregnancy in mammals. It plays no role in the milk let-down process. On the other hand, the other options listed can all help stimulate milk let-down in a lactating dairy cow. Oxytocin is a hormone that is naturally released during suckling or milking and stimulates milk let-down. The presence of a calf or milker also mimics the natural suckling process and can stimulate milk let-down. Additionally, providing feed can stimulate the release of hormones that aid in milk production and let-down.
