Because a growing proportion of the beef output in many countries originates from dairy
herds, the most critical decisions about the genetic merit of most carcasses harvested are …

Despite substantial advances in milk production efficiency of dairy cattle over the last 50
years, rising feed costs remain a significant threat to producer profitability. There also is a …

Selecting for lower methane (CH 4) emitting animals is one of the best approaches to reduce
CH 4 given that genetic progress is permanent and cumulative over generations. As genetic …

For heifers, beef and moderate-yielding dairy cows, it appears that the fertilisation rate
generally lies between 90% and 100%. For high-producing dairy cows, there is a less …

It may be possible for dairy farms to improve profitability and reduce environmental impacts
by selecting for higher feed efficiency and lower methane (CH4) emission traits. It remains to …

A new breeding value that combines the amount of feed saved through improved metabolic
efficiency with predicted maintenance requirements is described. The breeding value …

ABSTRACT The Resilient Dairy Genome Project (RDGP) is an international large-scale
applied research project that aims to generate genomic tools to breed more resilient dairy …

Our long-term objective is to develop breeding strategies for improving feed efficiency in
dairy cattle. In this study, phenotypic data were pooled across multiple research stations to …

In this study a 3-dimensional (3D) camera system was set up to measure individual feed
intake of dairy cows in a commercial in-house setting. The system was developed to identify …

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 …
