By: Nor-Feed is pleased to announce the publication of a new peer-reviewed study in the journal Animals, highlighting the positive effects of Nor-Spice AB®, a standardized natural citrus extract (SNCE), on broiler chickens. The research demonstrates that supplementing broiler diets with SNCE leads to notable improvements in growth performance, gut health, carcass quality, and overall animal welfare.
In this study, broiler chickens receiving a diet supplemented with 250 g/T of SNCE exhibited significant enhancements in several key areas compared to a control group:
• Improved final body weight, European Efficiency Index, and carcass quality in broilers;
• Enhanced welfare indicators, including a reduction in Footpad Dermatitis occurrence;
• Better gut health, with measurable improvements in putrefactive short-chain fatty acids and gut integrity.
This study adds to the growing body of evidence supporting the efficacy of Nor-Spice AB® in enhancing animal performance. Its natural composition makes it an excellent choice for producers seeking effective and sustainable feed additives.
Nor-Spice AB® is composed of natural citrus extracts and is standardized in citroflavonoids and pectic-oligosaccharides (POS). These components stimulate the growth of Acidophilic bacteria, leading to improved feed efficiency and animal growth.
A special congratulations to Dr. Sekhou Cisse and all our partners for their outstanding contributions to this research: Marta Mendel, Management Institute Warsaw University of Life Sciences, University of Warmia and Mazury in Olsztyn, and all the co-authors.
