I loaded up Betty and took her to slaughter today. She was open, and awful lame on a front foot. I have an offer to buy at local auction prices - what I have found online is a range of $25 - $37.75 per hundredweight for D3-5 cows. Is the carcass weight hot on the rail going to be around 62% of her live weight, as with steers, or will it be worse, or better? I will have to estimate her liveweight from the carcass weight. She was a 3.5 yr old Hereford / Angus cow, large frame, was starting to lose weight but still had some fat cover. Do these values seem reasonable? I am on Vancouver Island, BC Canada. Thankyou.
