[QUOTE="SRBeef, post: 920139, member: 7509"] Last time for me, simply put: - Hereford gestation period is 283 days from AHA website. - A year has 365 days - 365-283 = 82 days - Therefore a cow has 82 days after calving to recover from calving, start cycling again and get rebred, otherwise her calving date keeps falling back every year. - If cows keep falling back, pretty soon you have almost no calving season at all. - "experts" generally agree the tighter the calving period, the better/more profitable the beef operation. - I personally do not want cows around that can not have a calf and get rebred within 82 days, provided I make sure she has proper nutrition and a good bull. - your statement above "I would still go with a 90 or even a 120 breeding and calving season." is greater than 82 days which means every year cows will fall back further and further. Over and out on this one. Jim [/QUOTE]
