[QUOTE="randiliana, post: 1001747, member: 2308"] # 7 is a purebred Shorthorn cow. Yes, the last 2 winters have been really nice, last year was nicer than this even. And our birthweights have dropped at least 10 lbs. There is info out there that says the BW are related to winter temps. I think it has something to do with blood flow concentration. [url=http://www.sites.ext.vt.edu/newsletter-archive/livestock/aps-07_03/aps-302.html]http://www.sites.ext.vt.edu/newsletter- ... s-302.html[/url] I read a study, where they took Hereford cows from one of the Northern states to Florida (I think) and vice versa. The cows in the north had 85ish lb calves, when they were moved to Florida they dropped to 60ish. And the cows from Florida had 60ish lb calves and when they were moved north they increased into the 80s. I wish I could find that study again.... [/QUOTE]
