Abstract

A preference test and a performance trial were carried out to examine weaned piglets feed intake response to diets containing either lactic acid,formic acid,calcium formate,or sodium benzoate (8 g kg-1 feed).In Experiment 1, throughout a 21-d post-weaning period,30 entire litters (306 piglets) weaned at the age of 30 d were allowed to choose between two organic-acid-supplemented diets. All of the four different organic-acid-supplemented diets were tested in pairs against each other,and the six possible combinations were lactic acid +formic acid,lactic acid +calcium formate,lactic acid + sodium benzoate,formic acid +calcium formate,formic acid +sodium benzoate,and calcium for-mate +sodium benzoate.Piglets preferred diets supplemented with sodium benzoate to ones supplemented with formic acid or calcium formate.The acceptability of diets supplemented with lactic acid,formic acid,or calcium formate was similar.In Experiment 2,until the age of 58 d,60 piglets from 10 litters weaned at the age of 28 or 38 d were fed non-acidified diets or ones supplemented with lactic acid,formic acid,calcium formate,or sodium benzoate.Feed consumption did not differ between piglets fed non-acidified and those fed organic-acid-supplemented diets. Growth performance was reduced by dietary calcium formate supplementation, while the performance of piglets fed other organic-acid-supplemented diets did not differ significantly from those fed the non-acidified control diet.The frequency of post-weaning diarrhoea was highest in piglets fed diets supplemented with calcium formate and lowest in piglets fed diets supplemented with formic acid.;
