Hoping for Heifers?
Learn the Latest in Artificial Insemination and Sexed Semen Practices at
Dairy Reproduction Workshop in January
Choosing the sex of your baby � your baby cow that is - is a developing
option for dairy and beef farmers who prefer heifer calves with good
genetics and the potential to be great milkers in their dairy herds and
breef brood cows. In January in Clinton, Essex, Franklin and St.
Lawrence counties, farmers looking to build their herds internally
through an on-farm breeding program, those interested in increasing the
number of heifer calves born on their farms, and producers looking to
improve their artificial insemination (AI) skills will find what they
need at the 2008 Dairy Reproduction Management Workshop.
The workshop will also provide a hands-on learning experience for using
the tools of AI on an actual cow reproductive tract.
Cornell Cooperative Extension is offering workshops featuring speakers
from Genex Cooperative, Inc., Select Sires and local veterinary clinics
and the hands-on AI practice opportunity in
� Clinton County on January 22nd � 10:45 am to 2:45 pm
� Essex County on January 22nd � 6:30-8:30 pm with speakers from Genex
and Adirondack Veterinary Hospital
� Franklin County on January 23rd �10:45 am to 2:45 pm, and in
� St. Lawrence County January 24th �10:45 am to 2:45 pm.
Pre-registration with your county Extension office is required by
January 18, 2008.
Jennifer Hunter with Genex Cooperative, Inc. will discuss and
demonstrate proper artificial insemination practices and best use
practices for using sexed semen based on recent research.
Sexed semen is semen that has had female sperm cells isolated from
specifically chosen sires to help producers increase the number of
heifer (female) calves born on their farms. Genex offers sexed semen for
both dairy and beef cows.
Hunter says, �This workshop is good both as a refresher for those
already practicing AI and those interested in starting to breed their
own cattle or use sexed semen. We will be talking about the various
factors that go into both the proper insemination practices and the use
of the sexed semen to assure successful results for your herd.�
Artificially inseminating cows is a process that requires skillful
attention to details - from proper semen handling and thawing to
placement of insemination straws in the cows� reproductive tracts. Those
attending the workshop will have the opportunity to practice placing an
insemination straw in a life-size dairy cow�s reproductive tract. Dye in
the straw that would normally contain semen will show the path semen
travels through the tract.
Kevin Ziemba is the Northeast Regional Marketing Manager with Select
Sires, Inc., a federation of farmer-owned cooperatives that sells semen,
including sexed semen, and such reproduction aids as heat detectors,
nutritional supplements and udder treatments. Ziemba will talk at the
workshops about how sexed semen is made, the challenges and
opportunities of using the sexed semen and where the future of the
Ziemba says, �Bull semen normally contains fifty percent XX sperm that
produce heifer calves and fifty percent XY sperm that produce bull
calves. I will talk about sexed semen is prepared with a higher rate of
XX sperm and will share the results of our trials comparing conception
rates using sexed semen versus the unsorted semen.�
A local veterinarian at each workshop will discuss protocols for
synchronizing insemination with a cow�s heat cycle. Most cows have a
narrow timeframe during which insemination is most likely to result in a
pregnancy, and impregnating a cow on the first AI attempt increases
reproduction program efficiency and reduces a farm�s costs.
Workshop organizer and Dairy and Livestock Educator Blake Putman with
Cornell Cooperative Extension of Clinton County says, �This program will
benefit herd managers and farm employees who want to increase
reproductive performance in their herds by improving their skills for
heat detection. If you have your own on-farm breeding program or have
experienced emergency situations in which you are forced to handle
breeding responsibilities under pressure, understanding when to breed a
cow and the proper artificial insemination technique are crucial in
reaching a successful pregnancy."
Pre-registration for the Dairy Reproduction workshop is required by
January 18, 2008. Contact your local Cornell Cooperative Extension
office. The program, made possible by Cornell Cooperative Extension with
support from the Northern New York Agricultural Development Program, is
expected to be offered in other NNY counties later in the year. # # #
