Abstract

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 305-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 separetely. The correlation coefficients between various characteristics were determined to be as follows: Characterr ± Sr (x)I. lactationII. lactationiii. lactation stagestagestage A0.507±0.108 **0.435±0.127 **0.393±0.155 * B0.318± 0.112 **0.296±0.135 *0.515±0.144 * C0.047±0.1250.356±0.132 **0.452±0.150 ** D0.587±0.101 **0.537±0.119 **0.745±0.112 ** * P (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
