1 Body condition score your cows and heifers 30 days before breeding season. 2  They need to be at around a Cdn BCS of 2.5 to 3 to be ready to breed. 3  Heifers should be at a Cdn BCS of 3 to 3.5 to be ready to be bred. 4  Anything lower or higher than that will decrease fertility in your herd. The optimum bull-to-cow ratio is 1 bull per 10 to 30 cows, depending on the size of the pasture, and the bull's age, promiscuity/libido and experience. 2  Some bulls, depending on the fertility rate of the cows and how many cows are in heat at one time, can breed over 50 cows in one season.
