Research Highlights from International Poultry Scientific Forum 2025
The International Poultry Scientific Forum (IPSF) 2025 was held on January 27 and 28 in Atlanta, GA, before the International Production and Processing Expo (IPPE). More than 1,630 attendees participated in this meeting, making it again one of the biggest annual poultry scientific gatherings worldwide.
This year, a record of 419 communications were presented, with 225 oral presentations and 194 posters.
Sessions started as early as 7:00 am, finishing at 5:00 pm.
A greater variety of topics were observed, and talks were related to:
Reproduction,
Physiology (22 oral and 14 posters),
Poultry nutrition (107 oral presentations, 50% feed additives; and 86 posters with 60% from feed additives),
Environment and management (18 oral presentations, and 18 posters),
Artificial intelligence and data management,
Pathology and poultry disease prevention (64),
Welfare and behavior (32),
Processing and products (12),
Further processing,
Food safety (55).
This article will highlight some of these presentations only in the breeders, reproduction, and feed processing areas. Readers are encouraged to attend this event next year and get a better idea of the research quality presented in this meeting.
BREEDERS AND REPRODUCTION
Cloacal feather trimming improves the reproductive performance of layer breeder roosters
Dr. Ricardo Pereira from the University of São Paulo discussed an experiment conducted under commercial conditions evaluating the monthly cloacal feather trimming of males to improve reproductive parameters.
Trimming feathers in roosters reduced infertility at 63 weeks between 1.14% and 3.26% compared to the control group.
Hatchability increased between 2.63% and 4.27%.
Dietary supplementation of spray-dried plasma improves semen quality in aging broiler breeders
Mario Lopes from the University of São Paulo presented results indicating that supplementation of rooster diets with 1% spray-dried plasma reduced morphological spermatozoid defects at 63 weeks of age compared to the unsupplemented group.
Late embryonic mortality was also reduced.
Ricardo Rauber from Vetinova, Brazil, presented an interesting mycotoxin risk assessment using data on 13 broiler breeder flocks with data from 25 to 70 weeks of age.
Their results indicated that fumonisin and deoxynivalenol (DON) reduced fertility, and aflatoxin, fumonisin, and DON reduced hatchability...
