A Tennessee bill, which should land on Gov. Phil Bredesen’s desk later this month, would consider artificial insemination a farm management practice, meaning that the state would no longer require veterinary supervision in order to artificially
A major disadvantage associated with frozen-thawed semen is the fertility of the semen, which can be considerably less than fresh semen. This can be problematic when deciding how many progressively motile sperm (PMS) are needed per breeding to
Breeding without boundaries; it sounds like science fiction. Yet today we can breed two animals from different time zones, even different continents, through advances in artificial insemination. In this article, we will delv
The equine breeding industry has evolved dramatically with the introduction of artificial insemination programs and advanced assisted reproductive techniques. While live cover breeding pro-grams are still a mainstay for specific breeds, many
Cooling and freezing equine semen damages cell membranes, which results in loss of motility and general viability known as “cold shock.” Most domestic species have high concentrations of polyunsaturated fatty acids (PUFAs) in the semen, but the
AI is a relatively easy, safe, and convenient method of covering mares with stallions from all over the world. As with all techniques, it takes skill to make sure all the proper steps are taken to provide the best chance for pregnancy.
Horseman?s Day, held for the third time as part of the annual AAEP convention, was another rousing success. There weren?t as many people in attendance as there were in San Diego last year, but they were just as enthusiastic. AAEP officials said
In his presentation “Deep Horn Insemination” at the Hagyard-Davidson-McGee Bluegrass Equine Reproduction Symposium Oct. 25, John Steiner, DVM, Diplomate ACT, discussed two ways to use minimal numbers of sperm deposited at the tip of the uterine
Sex selection of foals prior to conception is highly desirable for horse breeders. Currently, sperm can be sorted by their X and Y chromosomes, improving odds of sex selection through artificial insemination. Flow cytometry measures DNA in cells
Only 20 miles from downtown St. Louis, Mo., is a 1,200-acre research farm owned by the nutrition company Purina Mills. On Oct. 3-5, 140-plus veterinarians and another 50 Purina Mills representatives gathered to tour that research facility and
The American Quarter Horse Association has eliminated all restrictions regarding the registration of foals produced through embryo transfer as part of an out-of-court settlement with a coalition of breeders.
For a couple of years, the
What type of solution is used to flush the tube after inseminating a mare and is it necessary?
We have show pony breeding stallions, and as of last year are doing almost all shipped semen. This year we are seriously thinking about expanding our business to offer semen collection and shipping services for outside stallions, which will
Presentations on reproduction have long been a hallmark of AAEP gatherings, and this year was no exception. The full-day reproduction session was split into two parts–the first was of a general nature, while the afternoon in-depth session
Published in the Jan. 26 issue of The Blood-Horse
Thoroughbred breeders who are happy with the industry’s staunch opposition to artificial insemination and embryo transfer should not get too comfortable.
“Don’t think
Laboratory assays have been developed which evaluate multiple sperm parameters on large numbers of sperm in a semen sample. These assays may prove useful in evaluating semen prior to insemination or at the beginning of the breeding season.
