* Neonatal Stage (Birth to Weaning): This is the stage from birth until the calf is weaned from its mother's milk, usually around 6-8 months old.
* Juvenile Stage (Weaning to Puberty): Cows continue to grow and develop during this stage. Females reach puberty around 12-18 months old, while males reach puberty around 18-24 months old.
* Adult Stage (Puberty to Death): Adult cows are fully mature and capable of reproducing. They continue to live and reproduce throughout their lifespan, which is typically 15-20 years.
Therefore, while there are distinct stages in a cow's life, it's not a clear three-stage cycle like insects.
