[QUOTE="Tbrake, post: 1522687, member: 22322"] Tbrake. Explain the comparisons in birth weights between fall and spring. That is interesting.[/quote] My spring calves are always 10-15 pounds bigger, Sometimes more. (Springs are born jan/ feb, falls aug/sept/oct). Some of the same bulls, and very similar cows. I have heard this from some old timer neighbors several times, but I’m finding it to be very true for me. I only explanation I have heard is the cold weather causes the cow to pump more blood, causing more nutrients going to the calf. True or not, I have no idea. Last winter was the coldest I remember, and I had some big calves. Averages close to 100lbs. Having calves now, some out of the same bull been averaging 75 lbs. talking to the county agent recently told me nutrition in the last trimester has very little to do with calf size. I graze a lot of wheat and turnips in the winter and used to pull the cows off about a month before calving. I had bigger than avrage calves last year, but so did the cows who where on decent hay and 3lbs of grain. Looking back though my records, the cows on wheat had calves 2-3 lbs bigger. Decent sample size 75 births on wheat/ turnips 119 births on stockpiled fescue/ hay/ 3lbs grain. Only 35 fall cows due, I will record their bw. I’m not the only one who had large spring calves, I’ve talked to people all over who are saying the same thing. General theory has been the abnormally cold winter over most of the country. [/QUOTE]
