Extract

The newly weaned pig has a limited capacity to secrete acid, which acts as a natural barrier against bacteria and activates pepsinogens (Kidder and Manners, 1978). We hypothesised that more acidic stomach conditions could be created by adding organic acid to the diet or by replacing inorganic phosphate, in the form of dicalcium phosphate, with phytase. The addition of formic acid to the diets of growing pigs has been shown to increase growth rate and feed conversion ratio. This effect was greater when supplementary phytase was also added to the diets, Jongbloed et.al (2000).
