How old can a heifer be when she reaches puberty or experiences her first heat cycle?
This depends on the breeding of that heifer. Some heifers that are genetically early maturing or have high fertility will start to experience puberty at around 5 to 6 months of age. Others that are more later maturing or have low fertility won't come into her first heat until she's 18 to 20 months of age.
No matter when a heifer goes into puberty, she can only be bred after she's had 3 or 4 normal heat cycles, when her weight is at least 60% to 65% of the weight of the mature cow herd or of the average mature cow weight of similar breeding to her, or when she is 15 months of age or older.
