[QUOTE="simme, post: 1771656, member: 40418"] A few thoughts on the discussion about running the bull with the cows year round with cows calving every 10 months. 10 months is 304 days. Gestation length is about 283 days. That would allow 21 days for that cow to recover from calving, start cycling and get settled on first breeding. I suspect that is a little optimistic. With good nutrition and fertility, 11 months is more realistic for a portion of the cows. People that have a defined calving season generally do that so that most calves are born in a selected fixed time period each year relative to their environment, forage and nutrition, weather, weaning time, selling/marketing plan, labor availability, etc. Those factors hopefully lead to uniformity and better performance.
