ABS History


Commercial bovine artificial insemination begins using fresh, quickly delivered semen. How quickly? Imagine small planes air-dropping parachutes of vessels containing semen to waiting technicians standing beside ground markers. Quite a picture, isn’t it?

Rockefeller (Rock) Prentice of Barrington, Illinois, forms the American Dairy Guernsey Associates (ADGA) of Northern Illinois, the precursor to today’s ABS Global. Three Guernsey sires form the core of an organization that would become the first privately owned bull stud in the USA.

In 1945, Holstein sires, the most popular dairy breed sold globally today, join the ABS lineup and quickly make a name for themselves (and a name-change for us).

In 1945, ADGA of Northern Illinois changes its name to the American Scientific Breeding Institute to reflect a greater number of Holsteins than Guernseys.

In 1947, a new year brings a new breed as Jersey sires join the company lineup.

In 1947, we move from Illinois to Wisconsin and change our name to Wisconsin Scientific Breeding Institute (WSBI).

In 1948, Rock Prentice and Dr. E.L. Willet establish the American Foundation of the Study of Genetics. A few years later, the foundation would create the first embryo transfer calf using a now-familiar process known today as – you guessed it – In-Vitro Fertilization (IVF).

The company breaks into the beef market when it adds Angus sires to the lineup.

In 1953, the first semen ampule to hold frozen semen is created. Made of glass, the ampule holds 1.2 cc of semen.

In 1953, the world meets Frosty, a healthy heifer and the first North American calf born from frozen semen artificial insemination. Thirty years later, history would be made again when the same semen successfully conceives another AI calf (clearly, frozen semen has a long, long shelf life).

In 1954, our research team adapts photographic equipment to track live sperm cells from each semen collection post-thaw, a process that would remain secret until published 19 years later in 1973.

In 1956, our researchers collaborate with Linde Corporation to introduce the industry’s first container for storing and transporting frozen semen using liquid nitrogen. The container was funded by the organization at a cost of $770,000 and establishes us as the first organization in the USA to rely 100 percent on liquid nitrogen-refrigerated frozen semen. Peru becomes the first country to receive frozen semen outside of the USA.

In 1956, Dr. Basile Luyet joins the organization. This Catholic priest and prominent cryobiologist perfects the process for freezing and storing semen.

Remember the parachuting semen of 1938? In 1956, thanks to our new transport container, drivers can now deliver frozen semen via the first truck route in the Midwest.

In 1958, our name is officially changed to American Breeders Service (ABS).

In 1959, Rock Prentice has trouble finding accurate, accessible production records to improve genetic evaluations. He discovers the Department of Agriculture in Beltsville, Maryland has the information he needs. The bad news: They lack funding to do anything with them. However, thanks to a generous donation from Rock Prentice, daughter records by bull and breed are published in the first AI sire summary.

In 1963, ABS geneticist, Dr. Robert E. Walton, introduces the Estimated Daughter Superiority (EDS) measurement, a young sire program to progeny test sires in a truly random fashion. EDS determines the value of bulls old enough to have milking daughters, which lays the foundation for the genetic evaluations used everywhere today. Dr. Walton would go on to become the 2nd president of ABS.

In 1965, DeForest, Wisconsin, USA becomes ABS headquarters.

In 1967, the infamous ABS Bullboard is erected along I-94 in DeForest. Since its inception, it’s hosted thousands of punny messages.

In his later years, Rock Prentice considers several buyers for the company, eventually choosing W.R. Grace & Company in 1967.

In 1968, ABS introduces the first computerized mating program, initially called Genetic Mating Service (GMS), which has made more than 68 million matings since its inception.

In 1968, ABS creates linear genetic evaluation systems that would later be adopted by the Holstein Association.

In 1971, ABS opens for business in France.

In 1975, Volume 1, No. 1 of the Genetic Trait Summary (GTS) is published in the USA. This first-of-its-kind dataset would become a valuable asset for mating cows with the GMS (which now stands for Genetic Management System) program.

In 1978, ABS invents and introduces a monitor ampule placed with stored semen, improving quality control by ensuring semen is maintained at the proper temperature.

In 1980, our patented, proprietary wind tunnel semen freezing system now freezes semen in the same package the customer receives.

In 1980, our Reproductive Management System (RMS) manages herd reproduction by utilising heat detection, artificial insemination breeding, synchronisation, and data management services provided by professional technicians.

In 1982, glass ampules are converted to clear straws and ABS begins offering 0.5 cc and 0.25 cc straws globally.

In 1987, ABS developed nuclear fusion transfer. This involves the cells of a cow’s embryo being loosened and individually placed into donor cow eggs that had their own DNA content removed. Once paired, the two were fused together to create a cloned embryo. These embryos were transferred to surrogate cows to create cloned calves. The first two calves born from this technology were named Fusion and Copy. Seems appropriate!

Ardshiel, Inc. acquires the company and changes its name to ABS Global. Has a nice ring to it, don’t you think?

Hola, México. In 1994, ABS Global opens a branch in yet another new country.

In 1996, ABS Global enters a joint venture with Incorporated Pecplan Bradesco, a Brazilian company that imports and distributes insemination products, adopting their stud as our own. The joint venture becomes known as ABS Pecplan.

Where’s the beef? In 1996, our partnership with Circle A Ranch and the Angus Sire Alliance makes ABS Global the exclusive marketing agent for the most profitable beef bulls.

In 1997, ABS Global announces the arrival of Gene, the world’s first cloned bovine calf. Even though Gene is in the womb at the same time as Dolly the Sheep, the world’s first cloned animal, Dolly is born first due to a sheep’s shorter gestation period.

Although rarely referred to as “the year of the teat dip,” in 1998, ABS Global introduces Valiant®, a line named after the influential ABS sire.

In 1999, Genus plc, a publicly traded company based out of the UK, purchases ABS Global.

In 2000, additives further our success as Powerstart™ silage additive enters the UK market.

In 2009, ABS China is founded.

In 2011, collections start in our Whenby, England facility.

As part of what was then called the Dairy InFocus program, cows with a lower genetic ranking are bred to beef with the resulting calves sold at a premium. Top-performing cows are used to create dairy replacement heifers. Today, Beef InFocus™ is recognised as one of the leading sources for premium dairy beef feeder cattle.

A partnership between ABS Pecplan and Rancho de Matinha, uses GrowSafe technology in 2012 to create IR$M, an economic feed efficiency index for Nelore cattle.

In 2012, ABS Global becomes the first company to use a proprietary database. Real World Data® (RWD™) contains millions of cow records from herds around the world.

Using RWD, in 2012 the company launches Sire Fertility, an index to measure a sire’s semen fertility.

In 2012, ABS Pecplan has another win with its introduction of ABS Monitor software for monitoring dairy herds.

In 2014, the Global Production System (GPS) computerizes the entire production process. From collection through processing and storage, bar codes are used to track the semen of studs around the world.

In 2014, our Net Profit Genetics™ program helps create more efficient, low-maintenance, and sustainable herds.

In 2016, ABS Pecplan and Agropecuaria Fazenda Brasil (AFB) partner to collect and analyze individual feed intake data on crossbred animals, the first time this has been done in a commercial environment.

NuEra Genetics™ is formed. It encompasses all proprietary ABS beef breeding programs, evaluations and indexes and produces superior genetics for beef supply chain profitability.

ABS becomes the sole owner of In-Vitro Brasil (IVB®). This provides ABS with the opportunity to accelerate the rate of genetic improvement offered our customers. IVB was started in 2002 to meet the growing demand for bovine IVF technology from commercial dairy and beef producers in Brazil.

Sexcel® Sexed Genetics is released! It is ABS’ sexed genetics produced using our own 21st century technology, which is gentle on the cells and enables ABS to deliver a product that helps contribute to improved herd performance. This new technology was developed by Genus plc’s in-house scientists and research team and is the most advanced since sexed semen was introduced years ago.

ABS XBLACK, new from NuEra Genetics™, is launched in Brazil. This begins a new era of genetic selection for crossbreeding by identifying the right genetics for animals finished in feedlot system. It is the first economic index that measures total system profitability in Nellore cows with Angus and European breed composite bulls.

Expansion is on the horizon for ABS Global in Wisconsin. The company purchases land in Leeds Township, Wisconsin, USA, for future development while also converting a third barn in Dekorra.

Expansion at Dekorra continues with the addition of 60 stalls to one current barn and construction started on another 120-stall facility taking capacity up to 420 stalls. Additional projects at Dekorra include adding feed rooms and a wash bay.
