Thankfully, had a fairly good calving season, with only three calves lost(one was a twin). Last year was a horrible year, when we lost 1/4 of all calves, plus two cows.
Our neighbour has a fairly bad season with c-section and huge calves.
Also a huge problem here is a shortage of feed. We tried to make as much feed as possible, so feeling comfy now, however many people are struggling.
We watch every newborn calf closely. The quicker they start nursing the better. However, if we see that the calf is slow to find a teat and can't manage it in ~12hours, come to help if possible. Some just needs abit of help, if mom is calm. If mom isn't one which would let us near her udder, then just feed colostrum and watch. Had a couple calves not nursing for three days, so had to bottle feed them.
