Evaluation of Dietary Supplementation with a Blend of Organic Acids and Cinnamaldehyde on Performance and Health Status in Weaned Piglets

Abstract

Simple Summary The period immediately after weaning is one of the most challenging stages in a pig’s life. In this moment, piglets are more prone to disease, often grow slower, and frequently antibiotic treatments are necessary to control health problems. However, the excessive use of antibiotics is a growing concern due to the development of drug-resistant bacteria, and there is increasing interest in finding alternative solutions. This study investigated whether supplementing a specific blend of natural compounds, including organic acids and cinnamaldehyde, to the diet of weaned piglets could improve their growth and health while reducing the need for antibiotics. A total of 148 piglets were divided into two groups and followed for 54 days, one receiving a standard diet (control) and the other receiving the same diet supplemented with a mixture of organic acids and cinnamaldehyde (treatment). Piglets fed the treatment diet showed increased growth and required fewer antibiotic treatments compared to those on the standard. They also showed a lower occurrence of ear lesions compared with piglets fed the control diet. No statistical differences in feed intake were observed between the experimental groups. These results suggest that innovative nutritional strategies based on the combination of organic acids and cinnamaldehyde can support animal health and reduce antibiotic use, contributing to more sustainable and responsible pig farming practices.
