Highlights

  • The results of the dispersion analysis of variance indicate that the strength of sires impact on milk yields – 2.11%, fat content – 4,21%, protein content – 8,2%, somatic cell count – 1,14% (P < 0,001)

  • It was found that the impact of this factor on the milk physicochemical properties and the number of mastiticases of their daughters is greater than the factor "line"

Summary

Introduction

The results of the dispersion analysis of variance indicate that the strength of sires impact on milk yields – 2.11%, fat content – 4,21%, protein content – 8,2%, somatic cell count – 1,14% (P < 0,001). Щомісяця у корівпервісток визначали добовий надій, вміст жиру, білка та соматичних клітин у молоці.
