As grain prices have increased dramatically in the past year, understanding the fundamental
genetic, cellular, and biochemical mechanisms responsible for feed efficiency (FE; g of …

Swine growth models have the potential to evaluate alternative management decisions and
optimize production systems. However, the lack of economical, yet accurate methods to …

The feeding of farm animals directly effects their growth, health, reproduction and ultimately
their economic value and is consequently one of the most studied areas of animal science …

Residual feed intake is defined as the difference between actual feed intake and that
predicted on the basis of requirements for production and maintenance of body weight …

Background Feed cost constitutes about 70% of the cost of raising broilers, but the efficiency
of feed utilization has not kept up the growth potential of today's broilers. Improvement in …

There is a growing body of evidence that there is genetic variation in beef cattle feed intake
relative to their liveweight and weight gain. Difference in feed intake, above and below that …

Residual feed intake (RFI) is a measure of feed efficiency defined as the difference between
the observed feed intake and that predicted from the average requirements for growth and …

Data were collected over the first 4 generations of a divergent selection experiment for
residual feed intake of Large White pigs having ad libitum access to feed. This data set was …

Past developments in livestock breeding have led to considerable genetic change in
production traits, but the follow-up of nutrition and management is often incomplete. The pig …

Background Residual feed intake (RFI), a measure of feed efficiency, is the difference
