I read the Riverston Livestock Martket report posted in the Wy Livestock Roundup a known herd for genetic improvement for many years and for bull sales. Sold 19 heifers weight 307 pounds and 20 head at 392 pounds.
I assume they had bull or steer mates somewhere. Must of been a bad year in north western Wyoming. Market report Novemeber16 and 17th.
Rather like guessing how long a piece of string is - what age were they? I notice no-one else here has mentioned the age of their calves and without that you don't know what rate of gain was. Does anybody work that out or are these "corrected for 200 day weaning" weights?
Ours this year averaged 534lb at 178 days which is bang on 3lb a day if you exclude a birth weight. 2.55lb actual gain if you factor in an 80lb average birth weight. Our average calf weaning weights are more influenced year to year by having a few more late calvers than usual in a particular year. We find the grass/milk contribution doesn't vary a lot from year to year although our calves maybe tend to wean heavier in a dry year than a wet one.
All that said we don't put a lot of emphasis on weaning weights - for us reducing the cost of running a cow is more profitable/important than maximising weaning weights.
