Exploring the use of random regression models with legendre polynomials to analyze measures of volume of ejaculate in Holstein bulls.

Journal of dairy science - 1 Feb 2007

Carabaño M J, Díaz C, Ugarte C, Serrano M

Abstract excerpt

Artificial insemination centers routinely collect records of quantity and quality of semen of bulls throughout the animals' productive period. The goal of this paper was to explore the use of random regression models with orthogonal polynomials to analyze repeated measures of semen production of Spanish Holstein bulls. A total of 8,773 records of volume of first ejaculate (VFE) collected between 12 and 30 mo of...
