Typically, the bulls get turned out with the cows on the 4th of July. For the bulls, it's celebration day. This year we're thinking of holding them back for a couple extra weeks to make sure we calve when the grass is growing again. Last winter was too harsh. Spring came so late that some calves were born with snow covering the ground. We'll have two angry bulls, but the cows will appreciate calving later in the spring when the grass is abundant.
The younger bull will run with the heifers, the older one with the cows. Using this gestation table for cattle breeding we can schedule delivery with the forage cycle of our pasture. If the bulls service date is July 4, then the calving date is April 12. Heifers sometimes deliver up to ten days early, cows up to ten days late. Our target date for 2015 is May 1. The bulls will have to wait until July 23, Sorry, bulls!
