Redefined and novel cow fertility measures in development of precision reproductive management tools and integrated genetic improvement

1) New phenotypes were extracted from the Herd Navigator data. Physiologial cycling measures were analyzed and publication is done. 2) Genomic data was added to female fertility evaluation, and a male fertility genomic evaluations were tested. Because of low h2 the models converged poorly, thus a QP transformation was developed which solved the computational problem.
