Today’s episode was filmed at the 2023 Poultry Science Association Annual Meeting in Philadelphia, PA and is the second podcast of two from PSA. Balchem’s technical team chose abstracts of interest from the meeting and those researchers are our guests today.
Emmillie Boot and Dr. Ramon Malheiros from North Carolina State University; Catherine Fudge from the University of Georgia; Dr. Lisa Bielke from North Carolina State University; Kyle Venter from the University of Pretoria; Leticia Orellana Galindo from Auburn University, and Dr. Ken Macklin from Mississippi State University; Cara Cash and Dr. Giri Athrey from Texas A&M University
Episode 79: 2023 Poultry Science Association Highlights Day 2

We kick off the show with Emmillie Boot and Dr. Ramon Malheiros from North Carolina State University. Emmillie’s research compared bell drinkers and gender-specific (different lines for roosters and hens) nipple-type drinkers for broiler breeders. She looked at the differences between egg production, egg fertility, and rooster fertility between nipple drinker lines and bell drinker lines. The major takeaway was that egg fertility was higher in the nipple drinker lines at the end of the flock cycle. (01:46)
Emmillie’s abstract is titled: “Comparison of bell drinkers and gender-specific nipple type drinkers, without catch cups, on broiler breeder fertility and egg production”
Our next guest is Catherine Fudge from the University of Georgia. Catherine is working to develop a histomoniasis infectious model for broiler breeders. Her lab is an Extension lab and a grower made an interesting observation that whenever he would place cedar shavings in his house, he noticed a drop in his insect population, and insects carry histomoniasis into chicken or turkey houses by way of a vector. Catherine began to evaluate this via benchtop experiments investigating the ability of cedar shavings and cedar extract to repel darkling beetles. (07:20)
Catherine’s abstract is titled: “Evaluation of cedar products against Histomonas meleagridis in vitro”
Next up is Dr. Lisa Bielke from North Carolina State University. Dr. Bielke presented research about the use of feed additives such as probiotics, symbiotics, organic acids, or essential oils as a way to prevent disease in poultry with the result being less antibiotic use. She emphasized that if birds are sick, and antibiotics are needed, then the birds should be treated with antibiotics, but that prevention is also key to bird health. (15:18)
Lisa’s abstract is titled: “Role of Feed Additives for Improving Health and Controlling Disease in Poultry”
Our fourth guest is Kyle Venter from the University of Pretoria. His research focuses on reducing dependence on rock phosphate by improving the digestibility of phosphorus in feed ingredients. Kyle pointed out that once phosphorus digestibility has been maximized from the diet, then one should formulate to the bird’s actual calcium and phosphorus requirements on a digestible basis, rather than using a total calcium, available phosphorus system. (23:12)
Kyle’s abstract is titled: “Evaluating the efficacy of three commercial phytase enzymes based on broiler performance and production economics”
Next in the lineup are Leticia Orellana Galindo from Auburn University, and Dr. Ken Macklin from Mississippi State University. Their research evaluates egg translucency and color intensity with egg quality parameters. Hatchability is a major issue in the broiler industry and previous research found that less translucent eggs had higher hatchability and darker color intensity eggs also had higher hatchability. In this abstract, Leticia evaluated the relationship between translucency and color intensity with internal and external egg quality parameters. (31:05)
Letecia’s abstract is titled: “Relationship between eggshell translucency and color intensity with egg quality parameters on broiler eggs”
When in Philadelphia, what better guest to have than Dr. Benjamin Franklin? Ben tells us about his scientific research regarding electricity and lightning and gives a perspective on agriculture in his day. (45:23)
Our final guests are Cara Cash and Dr. Giri Athrey from Texas A&M University. Cara’s research is data analysis based and she modeled the impact that decreasing broiler breeder fertility could have on broiler production, the climate, and the economy. Her model predicts that declining fertility could result in large increases in the amount of feed required for broiler production and the amount of greenhouse gasses created by broiler production. (49:14)
Cara’s abstract is titled: “The Effects of Broiler Breeder Fertility on Global Food Security”
