I do test at some farms who keep the milk from the high SCC girls to feed to the calves (they put them on the bucket) ... it's a shame they can't just chuck the cow in there with the little ones and let her mother them, too!
I suppose most farms aren't set up to accommodate that, though.
I think it's sad when calves have to live in those little domes ... where they can't even see another of their species! Or have any interaction ... they ARE herd animals, after all! A human baby will die if it isn't held and touched ... why do we think a calf will thrive under such circumstances. Of course, they survive and grow, but ...
Another thing is F&L, specifically muscle development. I have seen some farms where hutch calves are raised on, basically, a leash ... just long enough to lie down (but not so long they can get tangled up and hang themselves). These calves cannot run or play ... how can their feet and legs develop properly?! Sure, when they're older they'll be in bigger pens or turned out, and they'll get exercise, but ...
My calves run all the time ... in fact, sometimes it seems they go through stages where all they do is run! There is no speed between "standing still" and "dead run"!
I just think if we made an effort to replicate more natural conditions, we'd get better results ... animals that were socialized properly would do better in a herd, no?! Less stress? Better feet and legs, stronger pelvic ligaments?!!!
I dunno, these are just some random thoughts from my observations ...
All I know is that both my little bulls, who have been raised on their mommas, in a small pasture where they can run and play and snooze outdoors or indoors as they please ... are HUGE!
I was just looking at Boo today, and marveling at how big he is ... the top of his back comes up above my waist (OK, I'm short, but he isn't even 4 months old yet!). Now, granted I am not all that familiar with bull calves (because only the heifers are kept on commercial farms) but even the vet commented, when he was here, how big and stout the boys are.
Maybe I will get some heifers next time around and can prove my theories by raising some exceptional girls. We can only hope, eh?!
