Professor Jennie Elizabeth Pryce (born 1972) 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. [1]
Pryce was born in Shrewsbury, Shropshire, UK in 1972. She attended Shrewsbury High School and then the Cheltenham Ladies College. [2]
Pryce became inspired by genetics through owning and breeding her pedigree, registered herd of Holstein dairy cattle, under the prefix of Severnvale Holsteins and decided from a young age to pursue a career in genetics. In 1994 she received BSc (Hons) 1st class from the University of Edinburgh, Scotland and a PhD in 1998 also from the University of Edinburgh in "The Genetics of Health and Fertility of Dairy Cattle" under the supervision of Professors Geoff Simm, William G. Hill, Robin Thompson and Roel Veerkamp. [3]
Between 1998 and 2001 Pryce was a dairy geneticist with the Scotland's Rural College, Edinburgh, Scotland. In 2001 she moved to New Zealand to take up a scientist position with the breeding company Livestock Improvement Corporation. Since 2008 Pryce has lived and worked in Melbourne, Australia where her main areas of research interest are genetic improvement of functional traits (especially dairy cow fertility and feed conversion efficiency), optimising breeding scheme design under genomic selection and development of dairy selection indices. [4] [5] [6]
Jennie is also a member of the International Committee for Animal Recording’s Functional Traits Working Group and the Feed and Gas Working group [7] and was also section editor of Journal of Dairy Science, a member of the Functional Traits working group of the International Committee on Animal Recording (ICAR) and a member of the scientific committee of the World Congress on Genetics Applied to Livestock Production. In Australia, Pryce sits on the Dairy Moving Forward Fertility group and Holstein Australia's Breed Development and Conformation Committee. [8]
In 2016 Jennie was the first non-North American recipient of the prestigious American Dairy Science Association J.L. Lush Award for Animal Breeding and Genetics - established in 1982, the Award honours the memory of Dr J. L. Lush, who dedicated his life to advancing the field of animal breeding. [9] In 2019, Jennie was named as Australia’s top researcher in the field of animal husbandry by research analytics firm League of Scholars; this award is based on number of citations for papers published in the top 20 journals in each field over the past 5 years. The winner must have done research work published in the 10 years immediately preceding the year of recognition, performed research in any area of animal breeding and genetics that had or has the potential for improvement of dairy cattle.

The 2018 Agriculture Victoria Awards category “Excellence in Scientific Impact” winner for ImProving Herds. ImProving Herds was an innovative and collaborative herd improvement research, development, extension and education project concluding in 2018. It was important because it spelt out the importance and role of herd improvement to dairy farmers and the broader dairy industry. It was significant because it quantified the economic importance of genetic improvement by comparing breeding indices to real economic farm data, which has only been done once before in the dairy sector. ImProving Herds culminated in one of Australia’s largest on-farm dairy events, “The National Muster” which was attended by over 300 farmers and advisors. [7]
The 2019 Agriculture Victoria Awards category “Excellence in Scientific Impact” winner for “Excellence in Discovery and Invention” for Classifying the fertility of dairy cows using mid-infrared spectroscopy Drs Phuong Ho, Tim Luke and Jennie Pryce from Genomic and Cellular Sciences have developed a model that can predict how likely a dairy cow is to conceive to first insemination with up to 77 per cent accuracy.

The Holstein Friesian is an international breed or group of breeds of dairy cattle. It originated in the Dutch provinces of North Holland and Friesland and in Schleswig-Holstein in northern Germany. It is the dominant breed in industrial dairy farming worldwide, and is found in more than 160 countries. It is known by many names, among them Holstein, Friesian and Black and White.
Dairy farming is a class of agriculture for the long-term production of milk, which is processed for the eventual sale of a dairy product. Dairy farming has a history that goes back to the early Neolithic era, around the seventh millennium BC, in many regions of Europe and Africa. Before the 20th century, milking was done by hand on small farms. Beginning in the early 20th century, milking was done in large scale dairy farms with innovations including rotary parlors, the milking pipeline, and automatic milking systems that were commercially developed in the early 1990s.
Dairy cattle are cattle bred for the ability to produce large quantities of milk, from which dairy products are made. Dairy cattle generally are of the species Bos taurus.
The Dairy Shorthorn is a British breed of dairy cattle. It derives from the Shorthorn cattle of Teesside, in the North Riding of Yorkshire and in Northumbria in north-eastern England. The Shorthorn was for this reason at first known as the Durham or Teeswater.
The Brown Swiss or American Brown Swiss is an American breed of dairy cattle. It derives from the traditional triple-purpose Braunvieh of the Alpine region of Europe, but has diverged substantially from it. It was selectively bred for dairy qualities only, and its draft and beef capabilities were lost. Milk yield was measured in 2013 at 10231 kg (22600 lb) per year; the milk has about 4% butterfat and 3.5% protein and is suitable for making cheese.
The Red Sindhi is a dairy breed of zebuine cattle. It is believed to originate in western Sindh and in the Las Bela area of Balochistan, now in Pakistan. It is widely kept in Pakistan, where in 2006 there were approximately 3000000 head; there are small numbers in India and in Bangladesh. Other names include Las Bela, Malir and Sindhi.
The Australian Friesian Sahiwal, is an Australian breed of dairy cattle whose development commenced in the 1960s by the Queensland Government. It is a combination of the Sahiwal, a dairy breed of Bos indicus from Pakistan and Holstein breeds, designed for the tropical regions of Australia. Cows produce approximately 3,000 litres of milk per lactation under tropical pasture conditions with a high resistance to heat, humidity, ticks and other parasites.
Canadienne cattle, also known as Black Canadienne, French Canadienne, and Black Jersey, are the only breed of dairy cattle developed in Canada. They originated in the 16th century, when French settlers brought cattle over for foundation stock to settle Canada. The Canadienne were the most common breed of domestic cattle in Canada until the late 19th century, when other breeds began to displace them. Today, the Hereford and Holstein have become the most common types of cattle in Canada. The Canadienne, though still found on farms and ranches across the nation, is now comparatively rare except in certain areas of the province of Quebec. Efforts by an active breed society and the Quebec government have been made in recent years to preserve the breed from extinction.
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.
The Tipo Carora or Carora is a Venezuelan breed of dairy cattle. It was bred in the early part of the twentieth century by crossing of local Criollo cows with imported Brown Swiss bulls. It is named for its place of origin, the town of Carora in the Venezuelan state of Lara.
Norwegian Red is a breed of dairy cattle developed in Norway starting in 1935.
A bull is an intact adult male of the species Bos taurus (cattle). More muscular and aggressive than the females of the same species, bulls have long been an important symbol in many religions, including for sacrifices. These animals play a significant role in beef ranching, dairy farming, and a variety of sporting and cultural activities, including bullfighting and bull riding.
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.
The Swedish Friesian, Swedish: 'Svensk Låglandsboskap', often abbreviated to SLB, is a Swedish breed of dairy cattle. It was established in about 1870 from imports of cattle of Dutch Friesian or German Black Pied type. From about 1970 it has been systematically cross-bred with the American Holstein-Friesian breed, to the point that the original Swedish type may be extinct. The name Swedish Holstein may also be used.It is a type of Swedish cattle breed.
Polled Holsteins are cattle born without horns but only occur in a small portion of Holstein cattle. The Holstein breed can go through selective breeding to produce polled calves. Polled is a natural trait for Holsteins but have not been bred for specifically. That is why a very small percentage of Holsteins are naturally polled. Bulls and cows can both carry the polled trait and pass it on to the progeny. Previous testing for polledness were not completely accurate because it was not looking for the gene directly until later discovered. Polled, also known as ‘hornless’ can result in the growth of scurs which are small loose horn growths that do not develop.
Lawrence (Larry) Raymond Schaeffer is an American geneticist, and emeritus professor of animal breeding and genetics at the University of Guelph, Guelph, Ontario, Canada.
Thomas Phillip Lecky, known as T.P. Lecky (1904-1994), was a Jamaican scientist who developed several new breeds of cattle. Lecky is known as one of Jamaica's earliest environmentalists, and a strong advocate for conservation of hillsides. His research in cattle breeding led to the development of three breeds suited the tropical climate: Jamaica Hope, Jamaica Red, and Jamaica Black. Jamaica Hope was the first breed of cattle indigenous to Jamaica. He is remembered as the Father of the Jamaican Dairy Industry.
