The American Dairy Science Association (ADSA) is a non-profit professional organization for the advancement of dairy science. ADSA is headquartered in Champaign, Illinois.
Consisting of 4500 members, ADSA is involved in research, education, and industry relations. Areas of ADSA focus include:
ADSA's top priorities are the Journal of Dairy Science, annual meetings, scientific liaisons with other organizations and agencies, and international development. ADSA is attempting to add value to potential new members through an emphasis on "integration of dairy disciplines from the farm to the table."
In the summer of 1905, the Graduate School of Agriculture was held at Ohio State University. Professor Wilber J. Fraser of the University of Illinois at Urbana-Champaign suggested a permanent "Dairy Instructors and Investigators Association". Attendees decided that Professor Fraser should discuss the matter further with university leaders and, if enough interest was indicated, call an organizational meeting at the 1906 Graduate School of Agriculture to be held at the University of Illinois, Urbana.Apparently, sufficient interest was raised, because Professor Fraser called interested parties to attend an inaugural meeting on July 17, 1906. Although 19 persons appear on the photograph of that first meeting, records indicate only 17 or 18 charter members joined what was then called "National Association of Dairy Instructors and Investigators". At this time, dairy schools existed at Cornell, Iowa State, Wisconsin, Purdue, Penn State, Ohio State, Missouri, Minnesota, Guelph (Ontario), and Illinois.
The second meeting was at the National Dairy Show in Chicago on 11 Oct 1907.Only 11 members were present when the meeting was called to order and 21 attended the banquet. At this meeting, the name of the organization changed to "Official Dairy Instructors Association".
The third meeting, held July 22 and 23, 1908 at Cornell University, was a significant success. 69 persons from Canada, 26 states, and the District of Columbia attended.By this time, the committees had become cohesive engines of change, developing score cards for consistently evaluating dairies and rules for judging contests.
At the 10th annual joint meeting in Amherst and Springfield, Massachusetts, on October 17, 1916, the organization voted to change its name to its current name. The name change was effective May 1, 1917.
By 1945, ADSA had 1,407 members. By 1985, ADSA had 3,000 members in fifty countries, owned a headquarters building with a staff of nineteen, provided management services for six other organizations, and published the Journal of Dairy Science and five journals for other organizations.FASS Inc., which was founded in 1998, currently provides association management services to ADSA and other clients.
From 1927 to 1997, ADSA held its annual meetings on college campuses. Since 1998, ADSA has held its annual meetings in convention centers.
ADSA's scientific journal is the Journal of Dairy Science (JDS). Volume I, Number 1 appeared on May 1, 1917 (also the effective birth date of the association's current name).Initially publishing bimonthly, JDS began monthly publication in 1934 and remains so today. JDS is among the top five most-cited scientific journals in the agriculture category.
Former presidents of the association include:
Buttermilk is a fermented dairy drink. Traditionally, it was the liquid left behind after churning butter out of cultured cream; however, most modern buttermilk is cultured. It is common in warm climates where unrefrigerated fresh milk sours quickly.
The Babcock test is an inexpensive and practical procedure to determine the fat content of milk. It is named after its developer, Stephen M. Babcock (1843–1931), professor at the University of Wisconsin.
George Malcolm Trout An American dairy industry pioneer, author, researcher, and professor emeritus in food science at Michigan State University. Trout is credited with finding the key to the creation of homogenized milk.
Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia). It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium. "Fever" is a misnomer, as body temperature during the disease is generally not elevated. Milk fever is more commonly seen in older animals and in certain breeds.
Κ-casein, or kappa casein, is a mammalian milk protein involved in several important physiological processes. In the gut, the ingested protein is split into an insoluble peptide and a soluble hydrophilic glycopeptide (caseinomacropeptide). Caseinomacropeptide is responsible for increased efficiency of digestion, prevention of neonate hypersensitivity to ingested proteins, and inhibition of gastric pathogens.
Otto Frederick Hunziker was a pioneer in the American and international dairy industry, as both an educator and a technical innovator. Hunziker was born and raised in Switzerland, emigrated to the U.S., and studied at Cornell University. He started and developed the dairy program at Purdue University when such programs were at their infancy. At this same time, Hunziker was heavily involved with the development of the American Dairy Science Association (ADSA) and the standardization and improvement of many dairy tests and processes. Hunziker wrote several of the leading dairy processing texts, which continue to be cited. After leaving Purdue University, Hunziker managed research and operations at a large, national condensary, continued to drive ADSA's standardization and publishing efforts, represented the U.S. at international dairy congresses, and facilitated dairy industry improvements across the globe.
The fat content of milk is the proportion of milk, by weight, made up by butterfat. The fat content, particularly of cow's milk, is modified to make a variety of products. The fat content of milk is usually stated on the container, and the color of the label or milk bottle top varied to enable quick recognition.
Shayle Robert Searle PhD was a New Zealand mathematician who was Professor Emeritus of Biological Statistics at Cornell University. He was a leader in the field of linear and mixed models in statistics, and published widely on the topics of linear models, mixed models, and variance component estimation.
Charles Roy Henderson was an American statistician and a pioneer in animal breeding — the application of quantitative methods for the genetic evaluation of domestic livestock. This is critically important because it allows farmers and geneticists to predict whether a crop or animal will have a desired trait, and to what extent the trait will be expressed. He developed mixed model equations to obtain best linear unbiased predictions of breeding values and, in general, any random effect. He invented three methods for the estimation of variance components in unbalanced settings of mixed models, and invented a method for constructing the inverse of Wright's numerator relationship matrix based on a simple list of pedigree information. He, with his Ph.D. student Shayle R. Searle, greatly extended the use of matrix notation in statistics. His methods are widely used by the domestic livestock industry throughout the world and are a cornerstone of linear model theory.
Karl Otto Hunziker was a Swiss professor of pedagogy, a pastor, and a politician.
A cannulated cow or "fistulated cow" refers to a cow that has been surgically fitted with a cannula. A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
The Latxa is a breed of domestic sheep native to the Basque Country of Spain. Mostly contained within the provinces of Biscay, Gipuzkoa and Navarre, Latxa are dairy sheep whose unpasteurized milk is used to produce Idiazábal and Roncal cheeses. There are two sub-types of the breed, a dark-faced and a blonde.
Controlled internal drug release (CIDR) devices are used in livestock for the synchronization of estrus. They are T-shaped devices with a silicone-coated nylon core. The silicone coating is impregnated with progesterone. CIDRs are inserted intra-vaginally using a specialized applicator. The flexible wings collapse for facilitated insertion and expand once placed appropriately within the vagina. The expansion of the wings retains its position; CIDRs have very high retention rates that may exceed 97%. A thin nylon tail remains exteriorized and is used for removal.
Lore Alford Rogers was an American bacteriologist and dairy scientist. He is credited with discovering that butter made from pasteurized sweet cream remained fresher than that made from sour ripened cream, while suggesting that surplus milk could still be sold as concentrated sour milk products. He refined the steps for manufacture of high quality Swiss cheese and, new to the United States, production of Roquefort cheese. He was instrumental in finding ways to discourage fungal growth in sweetened condensed milk and preventing losses in evaporated milk from heat coagulation.
Professor Jennie Elizabeth Pryce is a quantitative geneticist based in Melbourne, Australia. Jennie is the DairyBio animal program leader in conjunction with her role as principal research scientist for Agriculture Victoria and Professor of animal genetics at La Trobe University.
Dr. Ernest Mercier, OC was a reputed agronomist in Quebec, Canada. Born on a family farm in Notre-Dame-du-Rosaire, he went on to do graduate studies in Cornell University and founded the Artificial Insemination Center of Quebec. After many years as the superintendent at a federal research farm, he was promoted deputy minister of agriculture of Quebec, a position which he held for 6 years. Retiring from his government work, he became a private consultant and collaborated with the Canadian International Development Agency and the Canadian delegation at the Food and Agriculture Organization on projects that took him around the world.
A Babcock bottle is a clear glass flask with a long graduated neck, used in the Babcock test to evaluate the cream contents of milk. It is also called a Babcock milk test bottle, milk test bottle, cream test bottle, and other similar names.
Louis Firth Nafis was an American entrepreneur and inventor, best known as the first manufacturer of the standard Babcock milk test bottle. He was born in Jersey City, New Jersey on November 1, 1884, and died on February 26, 1955, in Evanston, Illinois.
Laura Hernandez is an American associate professor of dairy science at the University of Wisconsin–Madison who studies endocrinology and lactation, especially that of dairy cows. Hernandez aims to apply the findings from the ungulates to humans having issues with breastfeeding.
Victor E. Cabrera is a Peruvian-American academic and researcher. He is a Professor and Extension Specialist in dairy farm management and Alfred Toepfer Faculty Fellow at University of Wisconsin-Madison’s Department of Animal and Dairy Sciences.
