Implication

Analysis reveals trends in milk yield and reproductive abilities across different lactations in Holstein cows, suggesting implications for dairy farming.

Key Points

Milk productivity showed a regular change with age, peaking until mature lactation and then gradually declining.
Cows exhibited stable milk yields through the 7th lactation, though longer lactation periods reduced overall industry efficiency.
Fat content in milk exceeded standards across all ages, with an increase noted as cows aged.
Proteins met breed standards in younger lactations, but older cows showed decreased protein yield, not meeting requirements.
