The International Poultry Scientific Forum (IPSF) 2023 was held between January 23 and 24 in Atlanta, GA, right before the International Production and Processing Expo (IPPE). More than 1,300 attendees participated in this meeting, making it again one of the biggest annual poultry scientific gatherings worldwide.
This year 365 abstracts were presented, with 165 oral presentations and 200 posters.
This article will highlight some of these presentations that won graduate student awards or were made by professionals on some key topics.
NUTRITION
Methodology for carcass data evaluation:
Determining the impact of nutrition on broiler carcass traits accurately is critical to make appropriate decisions. Sample size in these evaluations is one of the factors to consider.
Mr. Caleb Marshall from Mississippi State University presented interesting information addressing statistical methodology to determine the best sample size and the personnel impact on processing metric variance.
This data suggested that when processing all birds subject to dietary treatment in an experiment is not possible, selecting birds within the final average mean of the pen plus or minus one standard deviation could be better than selecting random samples of birds.
Ileal phosphorus (P) digestibility:
Animal feed phosphate is a nonrenewable resource. Improving precision in P nutrition is a vital need for sustainable poultry production.
Poultry accounts for almost 50% of animal phosphate consumption. The assays to estimate relative bioavailability have multiple limitations or issues with accuracy.
One is establishing an appropriate ileal digestibility value for
