Estimates of genetic trends for daily milk yield and somatic cell score of primiparous Holstein cattle in Iran
Genetic and permanent environmental correlations between milk yield and somatic cell score (SCS) were estimated. The data set used in this analyse contained a total of 204,438 test-day (TD) observations of milk yield and SCS from 22,903 primiparous daughters of 554 dairy Holstein sires. A multiple-t...
