Bovine (Cow) Genome Effort
NIFA-funded research in the laboratory
of Harris Lewin at the University of Illinois
has led to the development of new technology
that is transforming the science and application
of animal breeding and genetics.
Professor Lewin's laboratory is at the forefront
of research in mammalian comparative and
functional genomics. Research in his laboratory
has led to the development of the most detailed
comparative map of cattle and human genes
in the world. Many scientists in the public
and private sectors have used this map to
identify genes affecting traits of economic
importance to the dairy and beef industries,
such as those that affect disease resistance
and the quantity and quality of milk and
In addition, Lewin's laboratory developed
the first large-scale microarrays for functional
genomics in cattle. These microarrays are
used worldwide to identify genes that are
responsible for resistance to infectious
diseases, the efficiency of cloning, and
the impact of nutrition on health and productivity.
Using the microarray technology, Lewin has
recently developed a new method (patent pending)
called “phenomic selection” for
enhanced animal breeding.
