MOOOOVE OVER TRADITIONAL BREEDING: Genetic profiling is changing the complexion of cattle breeding.HOLSTEIN ASSOCIATION USA A few days before the annual World Dairy Expo, bovine competitors start arriving so they can acclimate to the Wisconsin autumn after traveling, in some cases, thousands of miles.


The Expo is the premier beauty pageant for the barnyard set, attracting tens of thousands of participants and spectators from around the world to ogle the cream of the crop. The animals undergo elaborate primping (blow-outs, pedicures, glitter dustings, etc.) prior to parading before the judges. Last year, the International Red & White Show at the Expo, a best-in-show competition for fawn-colored Holsteins, hosted an exquisite set of specimens.

About a dozen cows, their giant udders swollen from not having been milked for half a day, posed in front of a roaring crowd of thousands, recalls Murray Hunt, who wrote about the Expo for his online publication The Bullvine.

If you have a few backyard does that you enjoy as a hobby, with little concern for genetic improvements of their offspring, then artificial insemination (AI) is probably not for you, assuming a suitable buck can be located for servicing the does. The expense of purchasing the necessary equipment and learning to do AI are likely not worthwhile. However, if there is an experienced inseminator in the area who is willing to work with your goats, then this may prove to be a viable alternative and certainly is much simpler than hauling your does in heat to the buck's home. 2) AI has some key advantages over natural breeding. 1) It eliminates the necessity of keeping one or several bucks on the farm (depending on herd size). 3) Once the decision to use AI has been made, the next step is to determine whether to do the inseminating yourself or pay someone else to do it.

Take, for example, the role of artificial insemination - one of the first reproductive biotechnologies to achieve widespread use - in enhancing milk production from the national dairy herd (Table 1). When used on a large scale, artificial insemination (AI) allowed reliable progeny testing of dairy bulls. Producers used the resulting information to identify those bulls whose daughters were proven to be excellent milk producers. Semen from identified bulls was used to artificially inseminate large numbers of cows. As a result, in the 40 years following introduction of artificial insemination with frozen semen, milk production increased 265% per cow. Rapid increase in milk production was possible because breeders focused primarily on a single trait. Unfortunately, improving genetics for production traits in beef animals proves more difficult. Using Artificial Insemination in a Commercial Breeding Herd — Beef Cattle. Artificial insemination (AI) has been a standard breeding practice in purebred cattle herds for many years.

There are also viable reasons to use AI in a commercial herd as well. Some of these reasons include: The use of genetics not usually available on a local basis.The production of replacement heifers with superior genetics.Coupled with estrus synchronization, consolidation of the calving season.The need for fewer bulls in the breeding season.Higher growth performance and calf value.The production of calves for specialty markets such as club calves.

Bloodlines boost productivity in dairy industry - Landline - 3/09/00:

Bloodlines boost productivity in dairy industry Reporter: Steve Letts First Published: 3/09/00 The Australian dairy herd's productivity is up. While improved pastures and farming techniques have played their part, genetics is the largest single factor involved in the gains. Indeed the Australian Dairy Herd Improvement scheme says the net return to dairy farmers from improved bloodlines over the last two decades has been around $20 million.

The Australian Breeding Values (ABVs) is a measure for dairy bulls, which includes milking speed, temperament and calving ease. However, the key figure is the Australian Selection Index (ASI). Artificial Insemination Helps Improve Herd Genetics, Calving. Artificial insemination (AI) is a critical herd-management tool for Bruce and Tena Ketchum, Plevna, Montana.

Artificial Insemination Helps Improve Herd Genetics, Calving

For 25 years, they’ve used AI in both their commercial and purebred herds of Red Angus. They depend on it to provide genetic improvement as well as labor savings at calving time. Affordability of top genetics is a key benefit of AI. “We can use a $40,000 bull or spend $20 a unit of semen,” says Bruce. “It’s hard to justify going out and spending $40,000 on a bull.” When selecting AI sires, the Ketchums look beyond a bull’s expected progeny differences. “The type of cattle we’re trying to raise are not mainstream-type cattle,” says Ketchum. Of their 300 head of purebred cows, the Ketchums AI some 220 head annually. They also AI 200 head of registered and commercial yearling replacement heifers. “We synchronize the heifers and time-breed on one day,” says Ketchum. Chapter 8.

Important terms in breeding and genetics

Scientists and animal breeders use biotechnology to produce healthier animals, make breeding easier and to produce more food for people. Animal breeders can improve the breeding process through techniques like artificial insemination, cloning and genetic engineering. Artificial insemination (AI) is when animal breeders place semen from a male animal into a female animal. The sperm from the semen meets with the female’s egg and a baby animal begins to develop. Artificial insemination makes it possible for breeders throughout the world to introduce the best traits into their herds, even though males with those traits might not live nearby.
