Calf and Heifer Specialist

I grew up on a 200 head Dairy farm and 500 head custom calf raising operation in North Central Minnesota. I started my own custom steer raising business while in high school. I raised dairy steers as wet calves to 300-400lbs. I also have over 10 years experience working and managing calves along with 10 years of shadowing veterinarians and interning at vet clinics. I graduated from South Dakota State University May 2011 with a bachelor's degree in Animal Science, Science specialization and minor in Chemistry. I choose to work for a year and then returned to SDSU for my graduate program. I graduated from SDSU May 2014 with a Master's in Biological Science, specialization in Dairy Science with an emphasis in Calf and Heifer Nutrition. My research was evaluating the growth performance and health of calves fed a modified accelerated 24:20 milk replacer at a moderate feeding rate compared to calves fed a milk replacer having similar or higher crude protein and lower fat concentrations. I have worked industry for 5 years as a Calf and Heifer Specialist. I currently reside in East Central Wisconsin with my husband and son.

Dr. Kevin McSweeney

Dr McSweeney grew up in the dairy industry in Virginia. After graduating from the University of Georgia with a degree in dairy science, Dr. McSweeney managed several dairies from Virginia to Colorado. He then moved on to work for Dr George Seidel at Colorado State University, helping to develop the process to sex sperm that is used today commercially. Dr. McSweeney then received his veterinary degree from CSU and immediately afterward moved on to a Master's degree at CSU focused on dairy cattle reproduction. It was during this time that Dr. McSweeney developed protocols around ultrasound and timed AI that he uses in his dairy practice, Bovine Reproduction Specialists, to improve synchrony to timed AI and conception rates. Along with the veterinary practice, Dr. McSweeney has created a training program in reproductive ultrasound, embryo transfer, and IVF for both veterinarians and non-veterinarians called International Bovine Training Solutions. To maximize the effectiveness of their training program and for research purposes, Dr. McSweeney also started a commercial dairy farm, Summit Dairy Learning Center near Greeley, Colorado.
