Avaliação de indicadores de produção fecal em equinos.

Abstract

The objective of this research was to evaluate the efficiency of LIPE® and NANOLIPE® fecal production indicators in comparison to the traditional method of total feces collection in horses. The experiment was carried out at Pito Aceso Farm, located in Itaúna - MG. The evaluated treatments consisted of concentrate and roughage diets of Tifton-85 (Cynodon spp.) preserved in the form of pre-dried silage or hay. The digestibility test lasted 28 days. Were used twelve mares of race Quarter Horse. Prior to the start of the test, the animals were randomly assigned to two groups consisting of the experimental treatments, which differed by the bulky offered in pre-dried silage or hay form. On the 24th day of the experiment, total fecal collection (TFC) was started. Fecal production was estimated using TFC, LIPE® and NANOLIPE® methods. External indicators were administered in capsules at a dosage of 0.25 g / animal / day. The statistical design adopted was the completely randomized with arrangement in subdivided plots. Fisher's test (P <0.05) was applied to evaluate the means. There was no interaction between fecal production estimation methods (total fecal collection and indicators) and nutrient digestibility of the evaluated diets (hay and pre-dried silage). LIPE® and NANOLIPE® fecal yield indicators can be used to estimate fecal output in horses as an alternative to the standard method of total fecal collection.
