Uso de acidificantes em dietas para leitões em desmame, e creche

Abstract

Physiological disorders associated with gastrointestinal immaturity and limited production of digestive acids and enzymes increase the incidence of diarrhea in post-weaning piglets. Acidifying agents have been widely exploited as performance enhancing additives. The objective of this review is to relate the main physical characteristics, mechanisms of action and the efficiency of use of acidifiers with the responses obtained from their use in diets for piglets and post-weaning nurseries. The use of acidifiers in diets for piglets in weaning and nursery stages improves the sanitary condition and performance. The positive actions of the use are associated with reduction of gastric pH, control of the intestinal microbiota and stimulation in the secretion of digestive enzymes. As a result, organic acids and salts can improve weight gain and feed efficiency. Formic, a, propionic, butyric, lactic, sorbic, benzoic, fumaric, malic, citric acids and the calcium formate salts, calcium lactate, calcium propionate, potassium diformate, sodium butyrate, magnesium citrate and lactate Can be used in food, although the acids: benzoic, fumaric, butyric and salts of these acids present a greater number of information in the literature. The combined use of organic acids and salts, in addition to blends, both administered in crystalline form, free or protected, present the best results for piglets in day care.
