The relationships between the rate of milk flow and milk yield in Simmental cattle are determined. Data of morning milking and daily milk yields and 303-day milk yields of 65 Simmental cows belonging to the Kazova State Farm were utilized. The cows were in their fourth lactation order. The data were obtained at 60 ± 15, 120 ± 15. and 180 ± 15 day periods of lactation for each trial cow separately. The correlation coefficients between various characteristics were determined to be as follows: Character r̄±Sr̄ (x) I. lactation II. lactation III. lactation stage stage stage A 0.507±0.108 ** 0.435±0.127 ** 0.393±0.155 * B 0318±0.112 ** 0296±0.135 * 0.515±0.144 * C 0.047±0.125 0.356±0.132 ** 0.452±0.150 ** D 0.587±0.101 ** 0.537±0.119 ** 0.745±0.112 ** * P<0.05 ** P<0.01 (x) A: 305 day milk yield-Daily milk yield B: " - Morning milk yield C: " -The rate of milk flow D: Morning milk yield - The rate of milk flow.
