Investigation of correlations and milking parameter distribution on cattle farms in eastern Croatia

The data of 303 Holstein Friesian and 235 Simmental cows were analysed. The results showed that in both cow breeds correlations existed between milk yield and average milk flow (0.39 and 0.49) as well as between milk yield and milking time (0.53 and 0.35). Negative correlations were found between average milk flow and milking time (-0.49 and -0.56). For the Holstein Friesian breed, 67% of the cows had a total milk flow in the range of 1.61 to 3.60 kg/min, whereas in the Simmental breed 72.2% of the cows had a total milk flow of 2.40 kg/min. The milk flow rate can be indirectly affected by selecting cows with higher milk production. the definition of an optimal milk flow rate and the determination of breeding goals for milking traits will lead to faster progress in milking trait improvement and an easier choice of quality breeding bulls and dams.
