Can calves be mated in 15 months?

The main results are as follows: 1. heifer generally has its first estrus at the age of 6 ~ 12 months, when the duration of estrus is short, the cycle is abnormal, and the reproductive system and its function are still in the stage of growth and development, which is not suitable for calf breeding.

2. Males and cows already have fertility during the sexual maturity period from 8 to 12 months old, but at this time the body is in an exuberant stage of growth and development. if they mate and conceive, it will affect their growth and development and future breeding and reproduction, and shorten their utilization years. The vitality and production performance of offspring are also low. Therefore, it is not suitable for breeding at this time, and attention should be paid to avoid wild mating in production.

3. The growth of bulls and cows is basically completed at the age of 2 to 3 years old, reaching the mature stage that can be mated. According to experience, the first mating age is 1.5-2 years old for female yellow cattle, 2-2 years old for male yellow cattle and 1.5-2 years old for imported bulls and cows. It should be based on the growth and development of the individual, taking the adult cattle as the standard, when the body weight of the individual reaches 65% to 70% of that of the adult, the body height reaches 90%, and the chest circumference reaches 80%, the initial mating age is the best.
