“…Freitas et al (2006) studied a blend of organic acids (levels of 0, 0.78, 0.84 and 0.90%) in the diet of piglets between 21 and 35 days of age and found that these treatments did not reduce the stomach pH of animals. These findings corroborated those of Braz et al (2011), who studied a blend of propionic acid, acetic acid, formic acid, citric acid and calcium, and Gomes et al (2011), who studied diets containing fumaric acid or combination with lactic acid or calcium propionate or combination of the three acids, for weaned piglets. They only found pH reductions in the colon, and the pH in the stomach and jejunum did not change.…”

“…Despite the discrepancies, the overall results indicate that diets containing acids are preferable to the control diet, especially with respect to the villus height and villus/crypt ratio of the jejunum, an important absorptive region and producer of enzymes. Specifically, Braz et al (2011) found that a blend of organic acids optimized the intestinal morphology. Conversely, Gomes et al (2007) found that the combination of 1% fumaric acid, 01% butyric acid and 05% formic acid in the diet of piglets at three weeks post-weaning reduced the villus height in the duodenum The numbers of Lactobacillus spp and Escherichia coli (Table 10) did not differ between treatments (P> 005), and the lack of Salmonella and Clostridium ssp were also observed.…”

“…Diferentemente de Teixeira et al (2003) que, avaliaram o efeito de diferentes acidificantes e suas combinações em dietas leitões de 21 a 60 dias de idade, e não observaram melhora em termos de conversão alimentar e consumo, embora tenham constatado diferenças de ganho de peso quando comparados ao controle. Os resultados deste trabalho também apresentam-se distintos dos publicados por Braz et al (2011) que, observaram melhor conversão alimentar de leitões desmamados alimentados com dietas contendo uma combinação de acidificantes em relação a dieta contendo antimicrobiano.…”

“…Estes resultados diferem dos obtidos por Tsiloyiannis et al (2001) e Owusu-Asiedu et al (2003 que observaram menores escores de fezes em leitões alimentados com antimicrobianos ou com acidificantes em relação à dieta controle. Por outro lado, os estudos de Utiyama et al (2006), Santos et al (2010) e Braz et al (2011 não identificaram efeito de mananoligossacarídeos, probióticos, acidificantes e antimicrobianos sobre a freqüência de diarréia, corroborando com este trabalho.…”
