This is a calf weaner. It gets inserted into the nose of the calf. The weaner creates a barrier so the calf can't get a grip on the teat to nurse. The little plastic points make it uncomfortable for the cow when he attempts to nurse, so she pushes him away. With this method, the calf gets to remain with his mother during weaning, less stressful than separation. We have to wean the year-old calves now so the pregnant cows get a couple months rest and can produce colostrum for their new calves, expected in July.
Rog inserted the weaner while I held Lindy still. We needed all our hands for this job, so no photos of the actual insertion. It was surprisingly easy once we got Lindy tied in place.
Now the challenge is to make sure the cows do not get mastitis as they dry off. I rubbed cooling Udder Relief balm on LaFonda last night, which she seemed to appreciate, but when I touched Lariat's udder, she kicked me. I am more worried about Fonda because Jerseys are bigger milk producers, and judging from that butterball calf of hers, she has been producing a lot!
