Oocyte quality is affected by many factors, among which the environment of growth and
maturation seems to be crucial. Studies show that well balanced oocyte energy metabolism …

Milk and milk solids production per cow is increasing annually in dairy systems. Peak milk
production is in early lactation when the uterus and ovary are recovering from the previous …

Interest is increasing in the feed intake complex of individual dairy cows, both for
management and animal breeding. However, energy intake data on an individual-cow basis …

This study investigated the hypothesis that dairy heifers divergent in genetic merit for fertility
traits differ in the age of puberty and reproductive performance. New Zealand's fertility …

The efficiency of milk production in pasture-based systems is heavily influenced by calving
pattern, necessitating excellent reproductive performance in a short-breeding season …

The objectives of this prospective cohort study were to characterize associations among
genomic merit for fertility with ovarian and endocrine function and the estrous behavior of …

Despite the importance of fertility in humans and livestock, there has been little success
dissecting the genetic basis of fertility. Our hypothesis was that genes differentially …

En esta revisión se analizan los últimos antecedentes sobre la relación entre la nutrición y
fertilidad en ganado lechero. Se establece la importancia de los niveles sanguíneos de …

The objective of this study was to determine the effects of uterine and systemic inflammatory
responses to uterine bacterial contamination at calving in dairy cows on the growth and …

The objective of the current study was to examine phenotypic fertility performance and
survival, and to gain insight into underlying factors that may contribute to greater fertility …
