NEWS 10 FEED & ADDITIVE MAGAZINE August 2025 USPOULTRY and the USPOULTRY Foundation announced the completion of a research project focused on developing a new sampling method for detecting Salmonella in broilers and turkeys. The project addresses a critical industry need for a consistent, cost-effective and practical sampling approach to accurately measure Salmonella levels at the flock level. The research is part of the association’s comprehensive research program encompassing all phases of poultry and egg production and processing and is made possible in part through proceeds from the International Poultry Expo, part of the International Production & Processing Expo. The study, titled “Project #F110: Identifying a New Pre-harvest Gold Standard Salmonella Sampling Strategy to Predict Salmonella Burden on Broiler and Turkey Flocks Arriving for Processing”, was conducted by Dr. Shariat, University of Georgia, and other research colleagues. It demonstrated that, for both broilers and turkeys, connecting Salmonella status (prevalence, load, serovar) between pre-harvest and post-harvest is complex. The project was conducted to determine the best live production sampling method for Salmonella detection and enumeration in broilers and turkeys. The researchers aimed to develop a recommended sampling strategy, including a timeline for collection, which correlates pre-harvest Salmonella with pre-intervention, post-harvest Salmonella.

The research shows that supplemented cows had better milk production with equivalent milk quality while ensuring their comfort under heat stress. Heat stress is, more than ever, a pressing issue and casts a shadow over the performance and profitability of dairy production. According to the data from the research, the dairy cows supplemented with Nor-Grape® BP-O exhibited significant enhancements in several key areas compared to the ones in the control group, such as: • +1.8 kg/day of milk with the same solids content, • Improved thermoregulatory responses with lower rectal temperatures and reduced heavy breathing, • Enhanced innate immune responses with higher neutrophil efficiency, • Better ruminal function seen by lower circulating level of urea and creatinine, • Lower liver damages assessed by circulating level of GGT and bilirubin. This means better cow comfort, metabolic efficiency, and milk quantity in the toughest summer conditions. Nor-Feed highlights NorGrape® BP-O as 100% natural and standardized in polyphenols extracted from grape. This solution provides water-soluble physiological antioxidants. Grape polyphenols from Nor-Grape® BP-O potentiate the animal’s antioxidant defences. Nor-Grape® BP-O is based on a specific bypass formulation.
