[QUOTE="medicinewoman, post: 920128, member: 18249"] SR, As I hear it, “almost” only counts in horseshoes. Not all cow cycle in exactly 23 days. And most are usually late with their first cycle after giving birth. Then there is the silent heat cycle issue which is very common in cows who have just given birth. True, but how many days does it take to reach that true 2nd cycle is the real question. A cow that gives birth and doesn’t cycle until 40 days after giving birth and has a silent heat for her 1st cycle and then can breed on her 2nd cycle is now out there past the 60 day breeding season at 63 days after the bull has been pulled. Well again you are changing the breeding season. 3 cycles = 69 days and you need to add at least 30 more days to recuperate from giving birth. Now you are talking about a 99 day breeding cycle, not a 60 day breeding and calving cycle. To cover a herd size on 173 in 60 days, if it is even possible, you would need at least 1 bull for every 25 cows and the cost of those bulls, including loss to injury, would far out way any thing gained from having a 60 day breeding and calving season. I would still go with a 90 or even a 120 breeding and calving season. But what ever works for you is fine with me. MW [/QUOTE]
