Bishop Reproductive Services was established by Brianne Bishop to provide a reproduction-focused practice model to producers in mid-Missouri.
Brianne’s interest in cattle reproduction was sparked when her family began using embryo transfer in their registered Herefords. While attending college at the University of Missouri-Columbia, she majored in Animal Sciences and completed coursework including reproductive physiology and reproductive management. These courses led to an internship where Brianne spent her summer in South Dakota on a ranch that heavily utilized AI in both their heifers and in the cow herd. In 2013 Brianne began a dual Masters-DVM program at the University of Missouri and was able to work with Dr. David Patterson, who pioneered the Missouri Show-Me-Select Heifer Program. Brianne’s masters research focused on Split-Time AI and the timing of GnRH for cows and heifers that fail to show heat prior to AI. She attended the International Embryo Transfer School in 2015 and began flushing cows at home for AbraKadabra Cattle Company.
Following graduation Brianne joined the team at Quail Valley Veterinary Clinic as a mixed animal veterinarian where she developed her skills in veterinary medicine and continued to focus on beef cattle reproduction. After two years she decided to follow her passion and start her own reproductive service. Brianne currently lives on a family farm in Millersburg with her husband, Logan, and two children, Ellie and Mason.
Reproductive tract scores and pelvic measurements are useful tools for heifer selection and breeding management. Performed about 30 days prior to breeding, examinations will identify heifers that are not expected to be cycling at that beginning of the breeding season or that have an abnormally small pelvic area.
Artificial insemination allows genetically superior bulls to be used in any herd. Bulls are selected based on EPDs for birth weight and calving ease, milk production and growth, or carcass traits. Estrous synchronization allows for breeding of all animals in a group on a single day and can help shorten the calving season.
Trans-rectal ultrasound performed between 35 and 90 days of gestation can be used to accurately determine fetal age for sire identification (ET or AI vs natural service sire) or due date estimation. Fetal sexing performed after 65 days of gestation is commonly used for marketing of bred females.
Superovulation of donors allows the best cows in a herd to produce multiple calves per year. Flushing can be performed at your farm and embryos can be transferred fresh or frozen for later use.
Donors need extra care around the time of superovulation. Donor housing allows cows to be managed to provide optimal flush results, without you dealing with the hassle of shots and breeding.
Planning your herd health program is important for reproductive success. Herd health appointments can be scheduled to vaccinate cows or process calves.
Donor housing includes daily care and feeding as well as management of superovulation, breeding, and flushing. A reproductive exam is performed on all donors prior to CIDR insertion. Donors are on site for approximately 31 days minimum, and can be picked up immediately following the flush or can stay on site for heat observation and breeding post-flush. Embryos are typically frozen, but fresh transfers can be scheduled as well.

We are excited to have construction underway for our future ET facility, featuring an indoor chute and alley system, ET lab, and office space. This will also increase our capacity for donor housing as well as individual breeding projects of 5-10 head.
