abstract = "The aim of this experiment was to investigate the effects of benzoic acid and chelates
in which copper (Cu), zinc (Zn) and manganese (Mn) were bound to methionine
hydroxy analogue on growth performance, intestinal morphology, intestinal microbiota
and digesta pH value of post-weaning piglets at 28 days of age. The experiment was
conducted on 96 piglets randomly assigned to one of four treatments (6 replicate pens
of 4 piglets each): 1) control (C) – microminerals were provided as sulfates of Cu, Zn
and Mn at 130 (80 at second phase), 100, 120 mg/kg in the first phase, respectively; 2)
chelates (CTM), microelements were provided as chelates of Cu, Zn and Mn at 130 (80
in second phase), 60, 60 mg/kg in the first phase, respectively; 3) benzoic acid (BA),
with the addition of 2500 mg/kg during both periods; 4) chelates + benzoic acid (CTM
+ BA), microelements were provided as chelates of Cu, Zn and Mn at 130 (80 in second
phase), 60, 60 mg/kg in the first phase, respectively, and 2500 mg/kg of benzoic acid
during both periods. Results showed that chelates and benzoic acid supplementation
not only improved the final body weight (p<0.05), average daily gain (p<0.05) and
feed conversion ratio (p<0.05), but also increased the morphology performance and
decreased the number of E. coli in the jejunum and ileum in the treated groups (p<0.05).
This study provides the evidence that dietary supplementation has beneficial effects on
the intestinal morphology and microflora of weaned pigs, which can partly explain why
growth performance of the piglets was improved.",
