[QUOTE="anewcomer, post: 1650595, member: 18748"] Bird dog, I know you know these numbers, but let’s figure for others who may be following. Your cow who got bred last Wednesday 11/11/20 will calve 8/20/21. To give a calf every 365 days, our goal, she must rebreed in 80 days, by 11/10/21. If we expand that to all your cows who calve in the first 21 days of your calving season, they would all need to be bred back by 11/31/21. If we figure we should be increasing body condition at least 30 days pre-calving, that would put us at 7/20/21. So for 130 days from 7/20/21 to 11/31/21 we would want these cows on an increasing plane of nutrition, especially post-calving and through peak lactation at 40-60 days. From your description, your forage base looks to be declining in both quality and quantity during this time, requiring supplementation. Do you also have a spring calving herd? [/QUOTE]
