So, as promised yesterday, I said that I would explain what records we keep for our heifers (females that haven’t had a calf).
At birth, the records are the same. We keep track of the cow number, the sire (or bull), date of birth, weight at birth, calving ease number and weaning weight (adjusted to 205 days). The only thing that is different, is when we decide to keep a heifer to include her in our herd.
As I’ve mentioned before in my blog, bull calves get white tags at birth, heifer calves get yellow tags. If a heifer is chosen to stay in the herd, she keeps that yellow tag until after she’s been bred with her first calf. Sometime between breeding and calving, those heifer tags are switched to a new cow tag, the chosen color for that year and a new number.
That’s why it’s so important to have those records. This way we can keep track of which calves came from which cow, which bull sired which calves, etc. This way, if we have really large calves, we can see if the bull is the problem, or if there are other genetic abnormalities or issues. Also, we can make sure that no heifer is bred to its own bloodline.
Boss Man writes down the calving information in a small notebook that he keeps in his pocket, then he transfers that information to his calving book that he keeps in the shop. We used to keep that information in the kitchen, so I could help with writing out tags and such, but one Easter morning, right before church, we found out that Scooter knew how to use a Z-tag marker.
