lleitis control -the benefits of vaccination

摘要

Pig production through the years has continuously evolved, as husbandry practices, environment control and disease management became more and more intensive - always aiming for the highest efficiency and farm profitability. Shortening the growth period from weaning to finishing calls for improved average daily gain, wherein having a healthy digestive system plays a major role, lleitis, due to Lawsonia intracellularis, is a widespread enteric disease of pigs that has been well documented to be a causeof global economic losses in the pig industry. The growth performance can be greatly affected to a point where nutrient absorption becomes significantly compromised depending on the severity of intestinal mucosal damage and lesion development.
