Improving weaner pig performance through the inclusion of activated mediumchain fatty acids

摘要

Alternatives to using antimicrobial compounds in pig production include the use of medium chain fatty acids (MCFA) with a total chain length of 6 to 12 carbon atoms (caproic, caprylic, capric and lauric acid). The MCFA have shown positive effects on intestinal morphology and modification of the gastrointestinal tract microbiota (Dierick et al. 2002). Aromabiotic~R Pig (Nuscience, Drongen, Belgium) is a proprietary blend of high purity activated MCFA that have been designed for use in pigs. The functional effects of MCFA lead to the hypothesis that the inclusion of AromabioticR Pig, with or without the presence of medication, will enhance the performance of weaner pigs.
