Sows being fed oregano during gestation and lactation breed stronger piglets, American researchers claim.
Researchers at the University of Minnesota, US, said that sows that were fed the herb – provided it was of good quality – bred approximately 1.1 piglet more than sows that did not receive oregano in their feed.
The piglets from oregano sow descendance were seen to be more vital. In addition, the interval between weaning and AI was shortened by three days on average with oregano sows.
Research from the German institute in Neu-Ulrichstein last year, claimed that oregano does not have a positive effect on finishers.
