[QUOTE="Aero, post: 642525, member: 2076"] There are almost no cows that can be in that shape and continue to produce a calf every 365 without heavy supplementation. it's amazing she hasnt gone down for the count in that shape. WEAN THE CALF! you need to adjust her weight to BCS 5 to get a real idea of what she has done. without adjusting you get a deceptively high percentage that can reach as high as 90%. If she weighs 900 lb and the calf weighs 650, she weaned 72%. But this cow is not doing you as much of a favor as you think; she is just putting more resources into her calf than she can sustain and you will be paying the bill to get her back into shape if she can recover. with each BCS there is 50-80 lb difference. that cow is probably a 1.5 - 2 (dont believe me? go to [url=http://www.cowbcs.info/photogallery.html]http://www.cowbcs.info/photogallery.html[/url]) to adjust her to a BCS 5, you need to add 150-280 lb (maybe more) to estimate what size cow she really is. With that, she is really an ~1180 lb cow that weaned a 650 lb calf which means [i]55%[/i]. one other thought is that the only place her weight has gone is into that calf via milk. milk is inefficient and for every 100 calories the calf receives, it takes about 130 calories out of the cow. with this idea in mind, if the calf gained an extra 200 lbs because the cow is a "good milker", it probably took 260 lbs off of the cow. high milk levels are not your friend and are very expensive to maintain. *4 minutes later - :lol2: you mean i went through writing that and almost every post in front of mine says the same thing? :dunce: [/QUOTE]
