The Feed Intake EPD will be incorporated into $F.
When is it happening?
December 5, 2014.
What’s the feed intake EPD?
The Feed Intake (FI) EPD is calculated in the background as a required precursor to the
Residual Average Daily Gain (RADG) EPD. Though it is not visible along with the other more
commonly known EPDs, it is available in AAA Login to the owner of those animals that have
individual feed intake data (i.e. GrowSafe information).
Which $ Indexes will be impacted?
To obtain a better estimate of profitability through the feedyard, the FI EPD will be incorporated
into the $F Index. $F and $G (Grid Value) together go into $B (Beef Value). In other words, $B
is a terminal index that focuses on profitability through the feedyard and on the rail.
When the indexes were first developed in 2004, very little feed-intake information was being
collected and the RADG EPD did not exist. At that time, $F attempted to account for differences
in feed efficiency by assuming that faster-gaining cattle are more efficient. There’s certainly a
high correlation between growth and efficiency, but the relationship is not perfect.
Why is it important?
The goal of the $Value Indexes is to explain expected differences in profit for the various phases
of production. Since the cost of feed has a major impact on the economics of cattle feeding, it’s
important to estimate that cost as accurately as possible.
Also, it’s important to note in the last 10 years (since the development of the $-Value Indexes),
the Angus breed has an increasing genetic trend for feed intake. Of course, this is expected as
we’ve also seen an upward genetic trend for growth and carcass traits. However, incorporating
FI into $F will give us a chance to moderate the trend for FI while continuing to improve for
growth and carcass (much like has been done for BW and the other growth traits since the
development of EPDs for those traits).
