here on last year's "job interview" post.)
From March 18-31, our 25 yearling heifers had their silage topped with MGA. MGA stands for melengestrol acetate, which suppresses the ovulation cycle for the heifers. That was the first step in getting the heifers to come into estrus (or heat) at the same time. These heifers were born in early 2015. In 2017, they will become mothers for the first time.
Yesterday, we rounded up the heifers for their turn through the working chute.
The Lutalyse also synchronizes the heifers' cycles. We do this to shorten the calving season for the heifers, which saves labor at calving time. (Well, it saves some labor for the humans - not the mama cows.) Because heifers are first-time mamas, we check them frequently in case they are having trouble calving.
Once the heifers got their shots, it was time for the bulls to join them. It will likely be a couple of days for "romance" to blossom, in other words, for the Lutalyse to work.
worked baby calves earlier.
