Indicators characterizing the milk flow rate of red dairy cattle
Abstract
In modern dairy cattle breeding, milk flow rate is of great importance for evaluation and selection of animals suitable for robotic milking under conditions of industrial milk production technologies. Using methods of correlation analysis, it is possible to determine the degree of relationship between milk flow and various morphofunctional properties of the udder and subsequently use the obtained result in the selection process.
The paper contains the materials of research aimed at studying the correlations between the main indicators of milk flow rate in red dairy cows.
In the course of research, the creation of a phenotypic database on milk flow rate indicators of red dairy cattle was initiated. Correlations between the main indicators of milk flow rate of cows were studied. Based on the data obtained, it was found that daily milk yield and lactation number had a positive effect on milk flow rate. Increase in daily milk yield by 1 kg is associated with an increase in milk flow rate by 0.068 kg/min (p < 0.001).
