Efeitos da nutrição parenteral ou enteral, associadas ou não à glutamina, sobre a motilidade gastrintestinal em equinos submetidos à inanição e realimentação.

This study aimed to evaluate the effects of enteral or total parenteral nutrition, associated or not with glutamine, on gastrointestinal motility in horses subjected to starvation and refeeding. 16 healthy, mixed-breed adult horses of both sexes, four geldings and 12 mares, with ages ranging from four to 14 years and an average body weight of 248.40 + 2.28 kg, were divided into four groups, four animals per group: Group I (ENTGL): enteral fluid therapy with electrolytes associated with glutamine; Group II (PARGL): total parenteral nutrition (TPN) associated with glutamine; Group III (ENTFL): enteral fluid therapy with electrolytes; Group IV (PARFL): parenteral fluid therapy. The experimental design was entirely randomized, in a 4x12 factorial scheme (groups x harvest time), for each phase, and their means compared by the Duncan test at the level of 5% significance. Regardless of the experimental group, there was a reduction in gastrointestinal motility during the starvation phase, which was more pronounced in the PARGL and PARFL groups. Once the food was restored, gastrointestinal motility returned to normal. [ABSTRACT FROM AUTHOR]
