Fight High Corn Prices with DNA
Leptin is a protein that affects the regulation of
metabolism. Leptin controls fat deposition and
marbling in cattle. A TT marker for Leptin controls
finish in cattle by increasing appetite and
decreasing metabolism. A CC marker for Leptin
decreases appetite and increases metabolism.
Feedlot operators know that Leptin does not affect
the first two phases of the growth curve. As long
as animals are grouped according to frame and their
Leptin genotype, we can increase the rate of finish
and marbling without affecting yield. The TT
genotype is homozygous. Used on any group of cows,
the CC genotype will be eliminated.
I increased the
profitability in my feedlot with the Quantum Leptin
test. This is the first genetic tool that has given
me the opportunity to more efficiently manage cattle
rather than grouping by their phenotype. By using
Leptin genotype TT in sorting, Ive achieved shorter
days on feed.
