Fixed yield responses to increased milking frequency.


Data from 19 literature reports that measured the effect of milking frequency on milk yield were summarized. When milking three times daily was compared with milking twice daily, the three times daily yield was 3.5 kg/d higher with a 95% confidence interval of 3.1 to 3.9 kg/d. Response of fat yield to increased milking frequency, from twice daily to three… (More)
