It has been a privilege to be a part of the AETA Board of Directors (BOD) over the last three years and an honor to serve as this year’s president. I have been blessed to be a part of this industry for 20 years. As Paul Harvey said, “The years don’t always add wisdom, but they do add perspective!”

The first meetings I attended were eye-opening experiences, and those BOD members were larger than life to a new college graduate trying to find a place to call home. Over the years, I have watched every BOD deal with their fair share of challenges. Each one, I am sure, feels theirs were the most difficult. We should all take the time to thank Morgan and FASS, and the two past presidents, Matt Dorshorst and Bill Croushore, for navigating AETA through two years of virtual meetings, zoom calls, and hotel contracts. But just as importantly, we need to thank all the businesses that continued to support the association and the industry without blinking an eye!

This is going to be an exciting year! Dr. Greg Schueller already has an amazing program set for our Annual Meeting in Louisville, Kentucky, from October 27 to 29, 2022. It is packed with timely and informative topics, and thankfully, for the first time in over two years we will be able to shake hands and interact with colleagues and longtime friends that we have greatly missed seeing. I promise you, Louisville will be a meeting to be remembered for a long time! Mark your calendars and make sure to attend.

In 2013, the AETA developed a strategic plan that is just as important today. It concentrates on 3 targeted areas for growth and betterment of the association, and this year’s BOD has goals to improve each one.

  1. Education
    1. Increase participation in poster session at AETA meetings
    2. Provide more exposure at veterinary school level: Curriculum, interactive courses
  2. Membership
    1. Encourage growth from within: Embryo transfer business (ETB) employees
    2. Increase exposure to new professional graduates
    3. Increase exposure to academia and encourage participation in our organization
    4. Increase exposure to other species utilizing assisted reproductive technologies
  3. Certification
    1. Improve certification exam format and knowledge base
    2. Continue to develop ways for members to differentiate and add value to themselves through recognition programs

As I have encouraged the BOD, I will equally encourage every AETA member to think differently than you have the past 20 years. As we propose new ways to recognize or educate members, we will see an increase in membership. As we increase membership, we will have more ETBs working in the industry and educating their clients on the importance of the AETA. This is nothing new to our industry, but it needs our attention again. 

I look forward to a productive 2022 and a reunion in Louisville at the 2022 AETA/CETA Annual Convention.

Clay Breiner, DVM

The numbers presented this year in the Report of the Data Retrieval Committee (DRC) of the International Embryo Technology Society showed that, despite the Pandemic, 2020 was a good year for the embryo transfer industry worldwide. The total number of embryos recorded increased in most countries and for all of the most representative species (cattle, horse, sheep and goats). In cattle, overall embryo production (in vivo and in vitro) increased 7.0% when compared with 2019, with more than 1.5 million embryos recorded [1]. To better understand the apparent contradiction between the positive trends in the embryo transfer industry and the economic and social crises caused by the COVID-19 Pandemic, a survey of practitioners from Brazil, Canada and the United States was conducted. These countries account for 74.6% of all the embryos recorded in cattle. However, their embryo industries are characterized by important differences, which limit extrapolations. Therefore, the current survey aimed to highlight how, in the perception of practitioners, the COVID-19 Pandemic affected the embryo transfer industry in each of their countries, as well as to reveal their expectations for 2021.

Embryo transfer (ET), including in vivo derived (IVD) and in vitro produced (IVP), is a routine breeding strategy in cattle operations as it enables the perpetuation of individuals with high genetic merit, improves herd performance, decreases calving interval, and increases fertility in cows under heat stress and repeat breeder cows (Hasler, 2014; Putney et al., 1989, Ambrose et al., 1999; Drost et al., 1999). ET can also be used to help producers control the sex ratio of their herd, which is often referred to as the “most economical genetic trait” as heifer calves are valued at a premium in a dairy herd due to their ability to produce milk. Additionally, ET is an important tool to enable “beef-on-dairy” strategies to add profitability to the dairy industry as dairy cows giving birth to beef calves keep the milking herd lactating while producing offspring which can be sold into the beef marketing chain. Due to these benefits, ET is becoming an increasingly common breeding strategy for the cattle industry, with some companies reporting a 20% increase year-over-year in number of embryos created and transferred (Genus, 2019). 

Unfortunately, success rates of ET are still low and limits the return on investment. Research from controlled studies report pregnancy rates of 70-80% from embryo transfer, but practitioners and producers in the industry encounter lower rates of these procedures on the farm or ranch (Youngs, 2011). The Canadian Embryo Transfer Association (CETA) reports pregnancy success of conventional fresh ET <57.3% successful with further reduced outcomes with IVF embryos (30%), which is comparable to pregnancy rates achieved in the United States (CETA, 2022). While causes of failed pregnancy are multi-factorial and can stem from embryonic, maternal, environmental stressors, or technician competence it is estimated that 20% of transferred embryos are likely non-viable at time of transfer and will never result in pregnancy (Prien et al., 2015, Vanroose et al., 2000; Diskin and Morris, 2008; Alfieri et al., 2019).

A contributing factor to this problem is the reliance on a subjective grading system dependent on a technician’s ability to grade embryos based on morphological characteristics. While practical and economical, the morphological analysis fails to account for many factors which contribute to an embryo’s health and viability including genetic defects, metabolic activity, acute stress, mitotic activity, and response to environmental factors. Therefore, emerging technologies which are non-invasive and non-subjective to evaluate embryo health can enable ET practitioners to select the healthiest embryos for transfer and subsequently improve pregnancy outcomes of IVF/ET in cattle.

The objective of this study was two-fold. 1.) To determine if embryo morphokinetic activity can be evaluated in short observatory periods and 2.) To determine if embryo morphokinetic activity can be used as an indicator of embryo health and viability.


Single vs. Group In Vitro Culture of Bovine Embryos: Research in Progress

Producing viable embryos and reducing the time between generations is an important, valuable, fast-moving, and trending topic amongst many progressive cattle producers and relies heavily upon effective Assisted Reproductive Techniques (ART’s). In vitro fertilization (IVF) is becoming one of the more popular ARTs as it allows for quicker generation turnover, multiple sires to be used with a single oocyte collection, and more embryos / calves in a given time period. Further, IVF might be chosen over conventional ARTs such as superovulation and embryo transfer because the conventional approaches produce few embryos per collection and the costs are significant. However, the number of oocytes recovered per transvaginal-follicular aspiration session is variable and thus the number of oocytes ultimately placed into culture may be low.  The focus of this preliminary study was to evaluate the percentage of ova that cleave and develop to the blastocyst stage when cultured in single vs. group environments.
