Özet:

In this study, the record of milk and dust production of the Black Alaca and Brown races crowned in 15 in Turkey has been evaluated. The real milk output of cows from the Black Alaca and Red races, the 305 day milk output and the smallest square average and standard errors of the lactation period were identified as 7160.6±33.0 and 6548.9±47.9 kg, 6729.2±33.3 and 6249.4±48.3 kg, 330.3±1.5 and 337.5±2.2 days respectively. The smallest square average and standard errors for the first sewage age and service period of the Black Alaca and Red races were identified as 845.8±6.6 and 908.3±8.6 days, 125.6±3.3 and 127.5±4.1 days, respectively. The impact of fat, race, year of breeding, season and lactation order on real dairy production and 305 day dairy production has been statistically significant (P < 0.01). However, the effect on the breastfeeding time of the breed is irrelevant (P > 0.05). According to the research findings, a conclusion has been made that the milk productivity performance of the study period is in good condition, however, the shortening of the service period will be appropriate.
