[QUOTE="SRBeef, post: 720734, member: 7509"] I was working with my cattle to day and snapped a picture of two of my cows in the lane coming back from the corral. Turns out these are 2 extremes of the cow size question. Here is a photo of my least profitable cow, long, deep #77 and one of my most profitable cows, scruffy looking #39. She is not one of my target 1200 lb cows but a pleasant surprise as a producer. Corrected to BCS 5, 77 had a weight at weaning 3 weeks ago of 1650 lb. Her actual weight was 1745 lb! Her very average steer calf had a 205 day ww of only 613 lb. #39 corrected to BCS 5 weighed 1250, her actual was 1325 lb. Her very nice heifer calf had a 205 day ww of 639 lb. This points out to me the benefits of data. I get concerned hearing about "phenotype" (looks?) over EPD's (data). [img]http://i877.photobucket.com/albums/ab336/SRBeef/IMG_2285_CowSize77vs39_120509.jpg?t=1260075432[/img] And from working with both of these cows in a rotational system, I don't need any lab RFI tests to tell me that 77 has consumed a WHOLE lot more grass, hay etc producing her calf than 39 has consumed producing hers.
