[QUOTE="medicinewoman, post: 920098, member: 18249"] SR, Let me rephrase that to make my self a little clearer. A 60 day breeding cycle is not long enough to breed all cows in the herd to calve within a 60 day time period. Both the breeding and calving season are too short. The best one can expect is about a 70% calving rate within that projected 60 day time frame. The keyword is “60 days”. The first problem you face is to get all cows to calve within a 60 day period so they can start to recycle to rebreed. The second problem is, not all cows recycle at the same rate. Some cows will recycle within 60 days, but many will be outside the 60 day time period. Some may even go up to 120 days depending on the difficulty of their past birth and other factors. Then there is the problem of having enough bull power to cover all those cows with SAGs in such a short period of time. ( 60 days ) Those 3 variables are more then enough to put 30% of any herd outside of a 60 day breeding and/or calving cycle. Not to mention that cows can be up to 2 weeks early or late in their calving. By reintroducing a cleanup bull or AI, you are changing the goal from a “60 day” calving cycle to some other goal. What you are stating is a NEW goal of 95% calving rate with no restrictions on the breeding season. That is an achievable goal. But by using only a 60 day breeding season, it is not! About the best you can expect from a 60 day breeding and calving cycle is 70%. Did I clear that up? MW [/QUOTE]
