[QUOTE="Son of Butch, post: 1216843, member: 14585"] TRUE The colder the average winter temperature the bigger the calf in spring. Also true, summer/fall calf birth weights are lighter than spring calves. Cows regulate body temp with blood circulation. In warm weather cows blood moves closer to the skin to aid cooling. In winter, blood circulation is kept closer to internal organs to conserve body heat. Somehow by keeping blood circulation closer to internal organs in cold weather it also increases calf birth weights. [2 separate studies - U of Nebraska and OSU reached same conclusion] [/QUOTE]
