[QUOTE="Nesikep, post: 915955, member: 9096"] Help me out with ROT and SWAG as well First off, what do you consider a "normal" gestation time... I found 288 days to be my herd average. I find that the mothers play a big role in gestation times.. and that they do pass it on to their daughters to an extent as well. I have a couple bloodlines that I start looking at from day 280, and another line that I can be pretty certain nothing will happen until 290. I can say that on average, bull calves are gestated about 3 days more. The longest gestation I've recorded is 296, several times now, and each time it was a bull. Though I have had heifers calves born at 295. The age of the cow also affects how long she carries (IMHO), Heifer cows usually being about 3 days earlier than when they mature. Also, the appearance of the cow (big, round, puddingbutt, udder) has nothing to do with the calf being overdue or not... I figured that out this year waiting on my heifer who looked 2 weeks overdue, but was on the day [/QUOTE]
