Genetic and phenotypic relationships among milk urea nitrogen, fertility, and milk yield in holstein cows.

Journal of dairy science - 1 Nov 2008

König S, Chang Y M, von Borstel U U, Gianola D, Simianer H

Abstract excerpt

The aims of the study were to evaluate the relationships among milk urea nitrogen and nonreturn rates at the phenotypic scale, and to estimate genetic parameters among milk urea nitrogen, milk yield, and fertility traits in the early period of lactation. Milk yield, protein percentage, the interval from calving to first service, and 56- and 90-d nonreturn rates were available from 73,344 Holstein cows from 2,178...
