The fetus is the most susceptible to disease of any animal on the farm. The cow is basically a barrier for the fetus. Good biosecurity practices are more impactful (important) than a vaccine protocol. But, in reality, the two work together. Most disease problems are the results of purchasing practices. (Buying a BVD-PI cow for example.) Modified live vaccines are not 100% safe. MLV vaccines can only be in pregnant animals if she has previously been vaccinated with a MLV. For pre breeding, should be used 30 days, and preferably 45 days, before the breeding season. Killed vaccines are not 100% effective. Two doses in time (2 to 4 weeks apart based on label) is still the best. The memory B and T cells created from two doses are what provide long term, lasting immunity. Why do we use the same vaccines year after year? There is a new approach called Prime Boost. In this approach an animal receives two rounds of modified live vaccine. Then sometime in the future the animal recei...

Let's be frank. Reproductive technologies, like most other technology in agriculture, work. Key is using the technology properly, perhaps even relying on expert advice, to be more profitable.

Beef Cattle Producer Survey – Cattle Lameness and Antimicrobial Usage in Missouri Researchers at the University of Missouri are conducting a survey of beef cattle producers in Missouri. The purpose of this research survey is to gather information regarding lameness in adult (greater than or equal to 18 months of age) cattle, including bulls, cows, and replacement heifers. The goals of this study are to determine the most common causes of lameness in beef cattle in Missouri and which antibiotics and treatments are most commonly used to treat these lamenesses. The survey is anticipated to take approximately 10-15 minutes to complete. To take the survey, please follow this link.  https://missouri.qualtrics.com/jfe/form/SV_1BV2TqAhImIBzJb The University of Missouri researchers thank you for your time and interest in participating in this survey!  If you have any questions about this research study, please contact: Pamela Adkins, DVM, PhD, DACVIM and Kelsey Walker, DVM University o...

University of Missouri USDA Funded Heifer Puberty and Fertility Project Participation Overview Project Goals  Fertility is critically important to both commercial and seedstock breeders. This project aims to improve genetic/genomic predictions for puberty and fertility of heifers by collecting DNA samples and relevant phenotypes, specifically relating to pubertal status and date of conception within the breeding season. This project is funded by the USDA-NIFA Animal Reproduction Program . The project is recruiting 2,500 Hereford and 2,500 Red Angus heifers , to add to a data set of 6,000 Angus heifers. Participation  To inquire about participating in the project, please first contact one of the project coordinators by email or phone:  Erin Larimore Phone: 660-281-5518 Email: LarimoreE@missouri.edu  Dr. Jared Decker   Phone: 573-819-0837  Email: DeckerJE@missouri.edu  Dr. Jordan Thomas   Phone: 573-289-959...

My older son Jaden Decker competed in the Missouri Junior Hereford Association Illustrated Speech Contest.  The Show-Me-Select Replacement Heifer Program has been very successful helping farmers and ranchers better manage beef heifers. We recently received USDA funding to use reproductive tract scores, pelvic measurements, and fetal age from ultrasound to better predict heifer reproduction EPDs. We are recruiting 2,500 Hereford and 2,500 Red Angus heifers for this project. Jaden discusses using these management practices and collecting this data in his herd.

One of the things I learned from my student Troy Rowan was that best part of breed association's junior national expos is the contests and activities.  So, when I saw the Junior National Hereford Expo Pee Wee Speech contest was online this year, we jumped at the opportunity.  Below is Jensen Decker's speech titled "Hazardous Hair Shedding".    Really excited about the growth this young man showed through this experience! Thanks for to the National Hereford Women for sponsoring the Pee Wee Speech contest.

Figure 1 from Durbin et al. 2020. We recently posted a preprint (a research publication that has not yet been peer reviewed) to the bioRxiv server. You can read the article here:  https://doi.org/10.1101/2020.05.21.109553   *Update: Peer-reviewed, published paper is available open-access here:  https://gsejournal.biomedcentral.com/articles/10.1186/s12711-020-00584-0  "Development of a genetic evaluation for hair shedding in American Angus cattle to improve thermotolerance" This manuscript describes our work with Angus breeders and Angus Genetics Inc. to create a hair shedding EPD for the American Angus Association. We learned a lot of cool things about hair shedding in this paper. Including how hair shedding is related to other traits and how hair shedding is related to the environment. 1) Negative Relationship Between Milk and Growth Something interesting to me was to learn more about the genetic correlation between weaning weight direct and weaning weight maternal...
