Differential effects of zinc oxide and a preparation of organic acids and an essentialoil on post-weaning diarrhoea

摘要

Weaning of pigs causes a growth check and can render pigs more susceptible to post-weaning diarrhoea (PWD). This condition is associated with proliferation of (3-haemolytic strains of enterotoxigenic E. coli (ETEC) in the small intestine. Numerous dietary and management strategies to control/mitigate PWD arc used, such as zinc oxide (ZnO), with the use of organic acids and (or) essential oils (EO) also reported to aid in the control of PWD (Vondruskova et al. 2010). This experiment examined the proposition that supplementation of a commercial product containing organic acids, cinnamaldehyde and a permeabilising substance in a diet for pigs infected with ETEC will decrease the incidence of PWD commensurate to ZnO.
