Before starting her PhD, Beauchemin spent several years in the feed industry as a Beef and Dairy Cattle Nutritionist[5] for a large feed manufacturer, where she gained an appreciation of the practical aspects of ruminant nutrition.[3][5] She began her research career as a scientist at Agriculture and Agri-Food Canada’s Lethbridge Research Centre in Alberta in 1988.
She was quickly promoted throughout her career, eventually achieving the top level of research scientist (RES5) in 2005. She is also an adjunct professor at the University of Alberta, the University of Saskatchewan, Utah State University, and a former adjunct professor at the University of British Columbia.[4] She often credits her many scientific achievements over the years to the contributions of many enthusiastic and talented technicians, students, and post-doctoral fellows, as well as to collaborations with other very capable scientists.
In the early stages of her career, Beauchemin's research focused mainly on dairy cattle nutrition, but in later years her interests widened to include both beef and dairy cattle.
She worked on various aspects of nutrition over the years and made many outstanding contributions to the dairy and beef industries in the area of rumen function and feed utilization.
Beauchemin developed a broad based research program to improve feed utilization of cattle, with specific interests in the areas of rumen function and feed digestion, acidosis prevention, physically effective fiber, forage and grain utilization, and enteric methane mitigation.
Beauchemin's research in the area of rumen function has led to guidelines that minimize ruminal acidosis in dairy cows and feedlot cattle, while maintaining high levels of animal production.[6]
She studied the dietary factors that contribute to subacute ruminal acidosis, as well as the role of physically effective fiber in stimulating rumen function and digestion.[6]
The results from these studies have contributed to dietary fiber recommendations for cattle.
Beauchemin is also internationally recognized for her work in the area of improving the utilization of forages by ruminants through the use of feed enzyme technology and other feed additives.[7] The focus of her work has been to identify the mechanisms of action whereby enzymes
improve feed digestion, such that feed enzymes that ensure positive and consistent results can be developed for the cattle industry.
More recently, Beauchemin extended her research to examine the larger environmental aspects of cattle farming. She developed a research program in the early 2000s to measure methane emissions from cattle with the goal of finding ways to curb those emissions.[5] Her research looks at the impact of ruminant production systems on greenhouse gas emissions,[7] with the aim of developing strategies to reduce the enteric methane that is produced by cattle as a byproduct of digesting fiber.[8] Her research is leading to novel nutritional approaches that improve air quality and lessen the environmental footprint of the livestock sector. Her research has found that by feeding a new methane-inhibiting supplement to cattle, t it is possible to reduce methane production by 30%.[5] In addition to curbing greenhouse gas emissions, reducing methane produced during feed digestion improves the efficiency by which dairy cows and beef cattle convert plant material into food (milk and meat) for people.
In 2011, Beauchemin was awarded the Bertebos Prize,[9] a prestigious award from the Royal Swedish Academy of Agriculture and Forestry, for her work on curbing methane emissions.
Beauchemin used the prize money to establish a scholarship fund at the Kwame Nkrumah University of Science and Technology in Kumasi, Ghana to promote the education of women.
So far, the scholarship has been awarded to three female graduate students pursuing graduate degrees in animal science.
Beauchemin served as an invited member of the Committee on Nutrient Requirements of Beef Cattle, National Academy of Sciences, Engineering and Medicine. The committee recently published the 8th Revised edition of the Nutrient Requirements of Beef Cattle, which is the feeding guidelines for beef cattle in North America.As the sole Canadian invited member, her contributions to the Nutrient Requirements of Beef Cattle, helped ensure that the publication was also suitable for Canadian conditions. Today this is universally used by nutritionists, veterinarians, and feed regulators such as the Canadian Food Inspection Agency.[4]
Since 1984, Beauchemin has been an active member of the American Dairy Science Association, the American Society of Animal Science, and the Canadian Society of Animal Science (past-president, 2000–01).[3]
Beauchemin retired from the public service in 2022.[10] Throughout her career, Beauchemin has published a total of 16 book chapters, 21 authoritative reviews, 390 peer-reviewed scientific papers,[11] with many of these papers published in high impact journals, and more than 850 technology transfer articles, abstracts, conference proceedings, and presentations.[4]
Beauchemin is recognized as a Woman of Impact in Canada for her scientific contributions as a woman in STEM (science, technology, engineering and math).[12]
