ARTICLE 72 FEED & ADDITIVE MAGAZINE October 2025 Managing conditions that are within a swine farmer’s control can contribute to efficient and profitable operations. While factors such as market prices and commodity costs are outside producers’ control, supporting the growth and developmental needs of piglets during the critical nursery phase can lead to improvements that carry over across the production cycle, ultimately boosting swine farm efficiency, environment and economics. Below, we address why the nursery and fattening phases are critically important production stages and discuss some best practices for supporting pigs in each phase. We also look at research that demonstrates how supplying a specific blend of organic acids during nursery can carry over into improved performance parameters and an improved return on investment (ROI). NURSERY PIGLETS: THE EARLY STAGE OF GROWTH The nursery phase begins once piglets are weaned, usually around 3 to 4 weeks of age, and continues until they are about 8 to 10 weeks old. During this “Organic acids can influence pig performance beyond the nursery stage, with benefits that carry over into fattening and contribute to the overall success of a pig farming operation. By investing in optimal nutrition, health management, and environmental conditions during the nursery phase, producers can enhance the performance of pigs during their transition to the fattening phase. The resulting carryover effects can lead to better growth rates, feed efficiency, and overall profitability in pig production systems.” HOW ORGANIC ACIDS IN WATER IMPROVE WEANED PIGLET PERFORMANCE INTO THE FATTENING PHASE Karolina Von Zuben Augusto Researcher Product Validation Trouw Nutrition, Brazil Giseli Heim Global Product Manager Trouw Nutrition, The Netherlands
