[QUOTE="elkwc, post: 1327097, member: 22295"] I was taught at an early age that assuming and assumptions many times make an a_ _ out of a person. Especially when basing them on low accuracy predictions. Most knowledgeable cowmen I've talked too say they don't pay any attention to an EPD until it reaches the 60% accuracy level and don't put much stock into them until they reach the 80% level. Until that level is attained accurate actual data along with knowledge of pedigrees and visual analysis is the best avenue for many of us commercial cowmen. Accurate data is a tool. Low accuracy data is many times worse and more misleading than no data at all. I call good management to include proper and complete nutrition for the cow.I don't babysit cows and we calf heifers. With proper development of the heifers and good bull selection we have had very few issues the last 3 years. If those figuring the data many times compiled on adjusted and manipulated data had to face the banker and get up at night they might change the way they do things. Just because cow size goes up a reasonable amount doesn't mean calf size has to go out of the roof. We sold many older cows last year when the prices were up. The majority went from 1,450 to 1,550. In the 3 years I've been involved with this set of cows there has been a handful of calves that would weigh over 90 lbs. We don't weight every calf but after my 60 plus years on this planet I have a fair idea of calf size. The majority have been in the 80-90 lb range with a few smaller. If a 1,400 lb cow can't have a 90-95 lb calf something is wrong. At least that has been my experience. [/QUOTE]
