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 …

The dairy industry has focused on maximizing milk yield, as it is believed that this maximizes
profit mainly through dilution of maintenance costs. Efficiency of milk production has …

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 …

Improving feed efficiency of dairy cows through breeding is expected to reduce enteric
methane production per unit of milk produced. This study examined the effect of 2 forage-to …

In the last decade, several countries have included feed efficiency (as residual feed intake;
RFI) in their breeding goal. Recent studies showed that RFI is favorably correlated with …

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 …

Improving feed efficiency (FE) of dairy cattle may boost farm profitability and reduce the
environmental footprint of the dairy industry. Residual feed intake (RFI), a candidate FE trait …

Our objectives were to determine the repeatability of residual feed intake (RFI) across
dietary protein levels and to determine the association between RFI and protein efficiency in …

Residual feed intake (RFI) is designed to estimate net efficiency of feed use, so low RFI
animals are considered for selection to reduce feeding costs. However, metabolic profiling of …

Methane emissions in ruminant livestock has become a hot topic, given the pressure to
reduce greenhouse gas emissions drastically in the European Union over the next 10 to 30 …
