The objective of the study was to assess the influence of lactation number, daily milk yield, somatic cell count and milk composition on the freezing point of milk of Polish Holstein-Friesian cows. The data comprised 3,067,343 test day milk samples collected in 2014 from 865,198 first seven lactations of 714,018 Polish Holstein-Friesian cows, made available by the Polish Federation of Cattle Breeders and Dairy Farmers. The cows calved in 20,043 herds in 2013 and 2014. Four lactation classes were created: first, second, third, and fourth to seventh (4 class). Analysis of variance using the MIXED procedure in SAS was applied to milk freezing point (MFP). The following factors were included in the analysis: lactation class, daily milk yield (1...
