TL;DR: In heifers there was a significant positive relationship between milk yield during the first 26 weeks of lactation and number of days to first observed post partum estrus, and in cows milk yield was positively related to number of services per pregnancy and calving interval.

TL;DR: The objective was to investigate the economic effect of prioritizing heifers for replacement at the herd level based on genomic estimated breeding values, and to compute break-even genotyping costs across a wide range of scenarios.

TL;DR: Several genes were identified whose expression levels in the bovine brain associated with the level of expression of estrous behavior, and several genes related to neurotransmission and neuronal plasticity are also involved in estrous regulation, with several genes and processes expressed in mid-cycle probably contributing to proper expression ofEstrous behavior in the next estrus.

TL;DR: In this article, the authors studied whether milk production levels affect health risks in dairy cows as influenced by genetic merit for milk yield and management factors, such as breeding value, milk frequency, and feed energy density.

TL;DR: Application of GS to gene introgression helped to speed up the process of introgressive of a gene while simultaneously increasing the genetic gain and reducing the inbreeding rate.
