lleitis and its affect on feed efficacy in pigs

摘要

Lawsonia intracellularis leads to different forms of porcine pro-liferative enteropathy - also know as ileitis. In the most common form no clinical signs like diarrhoea or sudden deaths can be observed despite pigs being infected with Lawsonia intracellularis. Infected pigs without any clinical signs show reduced weight gain, lower feed efficacy and increased body weight variation. Based on five trials, including 191,748 pigs, focus here is given to the effect of ileitis on the reduction of the feedefficacy and the prevention of ileitis by vaccination.
