Expected progeny differences (EPDs) from the fall 2008 international Limousin genetic evaluation now are available through various features of the North American Limousin Foundation (NALF) Web site. Pedigree and performance records for more than 2 million Limousin-based cattle in the United States and Canada underpin the latest sire summary, which includes more than 1,900 bulls.
Beginning with the latest analysis, Angus Genetics Inc. (AGI) is calculating the Limousin breed’s EPDs and accuracies for birth, weaning and yearling weights; milking ability; and scrotal circumference.
“On the surface, cattle producers are unlikely to notice any differences in the new evaluation,” said Kent Andersen, executive vice president for NALF. “Under the surface, however, there are some distinct differences, especially for breeders and commercial users of Lim-Flex® genetics.”
Now that AGI is conducting NALF’s evaluation, using improved hereditary ties to Angus seedstock, genetic predictions for Lim-Flex animals are the most timely and reliable of any for Angus-influenced hybrid seedstock.
In addition to EPDs for 13 economically relevant traits, NALF’s evaluation includes its 3-year-old Mainstream Terminal Index ($MTI), which simplifies mating decisions by ranking animals for expected net economic merit through simultaneous consideration of many traits.
$MTI combines calf survival, weaning and yearling weights, average daily gain (ADG) in the feedyard, feed intake, dressing percentage, yield grade, and marbling, explained Lauren Hyde, director of performance programs for NALF.
