PSA Insights
All of you will be familiar with our Poultry Science Journals – Poultry Science® and Journal of Applied Poultry Research (JAPR). Each journal has its specific objective, with Poultry Science® covering primarily original papers, research notes, symposium papers and basic science reviews, while JAPR focuses on original research reports, field reports and reviews on a variety of topics. What you might not be as familiar with is the rise in importance that these journals have achieved worldwide in the last few years! Acknowledgement of journal importance is based on a ranking system – referred to as IMPACT FACTOR, which relates to the number of times that papers within the journals are cited. The more citations – the higher the impact factor! Well – the impact factors of our journals have increased substantially. In the year 2000, Poultry Science® had an impact factor of 1.07. This has risen, and in 2020, the journal's impact factor is now 2.659. JAPR’s Impact Factor has also risen – from 0.745 in 2010 to 1.015 in 2019! There are many people involved in producing these journals, and a special thank you should go out to the Editor in Chiefs, Subject editors, Associate editors, reviewers, authors, PSA members, Poultry Science staff and any others for helping to create these amazing journals!

A final interesting note is that this year, the journal Poultry Science® celebrates its 100th year! It was first published in 1921, with 2 issues in total produced (with a total of 64 pages)! Be sure to watch for celebrations of the Poultry Science® journal at this year’s Virtual PSA Annual Meeting in July!

Where did you grow up and did you have poultry in your youth?
I grew up on a small diversified farm (80 acres) in East Central Iowa (20 miles north of Cedar Rapids). We milked 12 cows, twice a day, 365 days a year. We also produced about 200 market pigs a year. My mother kept a flock of about 100 fryers that were grown in the spring. They were produced for sale to local friends and neighbors who wanted fried chicken for Sunday dinner. At that time, a fried chicken dinner was considered “special”. My mother also kept a flock of about 400 breeder hens that produced hatching eggs for sale to a local hatchery. The chicken income was my mother’s money that she could spend on house expenses. We usually had two or three bantam hens and a rooster “free ranging” the farmyard. The baby chicks were sooo cute.

What was your first job out of school and what were your responsibilities?
In the spring of 1960 I received a PhD in Animal Science from the University of Illinois. The research for my Thesis was based on “The Phosphorus Requirement of the Weanling Pig”. Dr. D. E. Becker (an outstanding swine nutritionist) was my major professor. Jobs were scarce. 1960 was two years after the enactment of the Delaney Amendment that barred the use of anything in animal feed that appeared to or might cause cancer. University and industrial research on new feed additives (feed antibiotics were the hot area) was grinding to a halt while everyone concentrated on determining what effect the Delaney Amendment would have on feed additives. New graduates were taking almost any job they were offered. I had fewer than a half-dozen interviews. I was interviewed by Dr. R. S. Gordin (Flash Gordin) and Dr. Ken Maddy (Big Foot Maddy) for a research position at Monsanto Co. I was offered a job and I took it. Only later did I learn my responsibility would be conducting research with chickens.  Dr. H. M. Scott (a giant of poultry research) was the head of the Poultry Division at the University of Illinois. I had spent many Saturdays at the poultry research farm helping with research projects. Dr. Scott must have given me a good recommendation. I really enjoyed research with chickens. Weighing a 2 pound chicken was a dream compared with wrestling a 100 pound pig.

My initial responsibilities at Monsanto were conducting poultry research with methionine hydroxy analogue (MHA) and ethoxyquin (Santoquin), Monsanto feed additives. I also participated in reporting the results of this research at Poultry Science meetings.

A year later, my life changed. Dr. Maddy believed that computer feed formulation was a new technology that Monsanto could use as a marketing tool. Ken recruited me to report to him and work on the development of the Monsanto least cost linear programming feed formulation program. I was given direct responsibility for developing the matrix values for feed ingredients and nutrient restrictions, and producing feed formulations that perhaps, might, be used commercially. I also conducted experiments to evaluate the formulations. Computer feed formulation was cutting-edge technology. We were not the first, but one of the first. I believe that Hobe Halloran (another giant of the poultry industry) was the first to produce and use computer generated feed formulas (about 1958). In 1961 most of the poultry industry, as well as most university professors were convinced that computer generated feed formulas would never work. There were just too many subtle decisions that could not be represented by 0’s and 1’s.

I became involved in the cutting-edge technology of computer feed formulation at the very apex of the development of the technology; a technology that would have an almost immeasurable impact on the economics and efficiency of poultry production (feed represents about 70% of production cost); a technology that would dominate my career for the next 40 years.

If you had a motto that applied to your daily professional career, what would it be?
If it is worth doing, it is worth doing right. I learned this through nonverbal observations of my father. Even if the project was trivial, like setting fence posts, each post must be vertical and set in a straight line.

If there is an issue ( problem), do something. Don’t procrastinate (Buffett calls it thumb sucking). Do something now. Even if it is wrong, we can fix it later. This was a working model of Foster Poultry Farms. I find it works well in everyday life.

What value does PSA membership offer you?
Poultry Science provides an ongoing and continuing connection to the people who are important to developing the new information, the science, of poultry and the poultry industry. Poultry Science provides the opportunity of reading about new developments and then meeting, one on one, with the people who are conducting the research, writing the papers, or implementing the science in production. Poultry Science provides the opportunity to interact with people who are smarter than I am. Poultry Science is also the opportunity to maintain and renew contacts with people who I like.

For years, the annual Poultry Science meeting was a highlight of the summer for our family. The first annual meeting I attended was held at the University of California at Davis in 1960. This meeting set a very high bar for annual meetings. I specifically remember the banquet was picnic tables in a vineyard. The middle of the tables was piled high with all manner of fresh fruit, cheeses, and bottles of wine. It blew me away.
What is your favorite poultry breed?
The ever-changing breed that is better every next year. Scientists estimate that genetics has accounted for 80% of the improvement in growth rate and feed efficiency. Genetics provides the potential for growth performance as well as other metabolic functions including disease resistance, heat tolerance, etc. It is the mission and responsibility of the nutritionist and production management to optimize the genetic potential to achieve profits and quality. Optimization is seldom at maximum of potential. At the same time, we need a program to preserve the “heritage”, “jungle” and “native” breeds that provide the genetic diversity important for the future.

Who is is your greatest cheerleader?
Edna F. Cash-Dudley. My wife of 40 years. Graduate of the University of California Hasting College of the Law. Nationally recognized family law specialist. I have four children and six grandchildren. The grandchildren are all lovely and talented women.

Interpretive Summary
Examining Laying Hen Welfare During Depopulation

Depopulation is a beneficial component of maintaining a healthy laying flock. However, because many commercial laying hens are not accustomed to being handled, the process of catching these birds can cause stress and injury.

This study looks at the effects depopulation has on birds in a noncage system.
Student Video Competition
This Year's Theme:
Create a video that highlights a specific group of poultry species raised for meat and/or egg consumption. For your species, be sure to touch on the benefits of poultry proteins derived from these birds and the time it takes to raise them from incubation to slaughter and/or egg production. Lastly, give 2-3 reasons as to why your species of choice is paramount (do not badger or insult other species).

$1,000 to go towards the winner’s poultry science program or poultry club at his/her institution.
