HIDALGO L, Víctor  and  VALERIO C, Henry. Digestibility and digestible and metabolizable energy of corn gluten, hominy feed and wheat by-product in guinea pigs (Cavia porcellus). Rev. investig. vet.

The aim of this study was to determine the digestibility of dry matter and the digestible and metabolizable energy of the wheat by-product, corn germ and hominy feed by the in vivo digestibility test in guinea pigs, using the technique of total faeces and urine collection. Genetically improved young male guinea pigs (n=15) were distributed in three groups and fed with three diets: a) Basal diet (100% wheat by-product, protected vitamin C and water), b) Mixture I (70% corn germ and 30% basal diet) and Mixture II (70% hominy feed and 30% basal diet). The nutritional values of the diets were determined. The digestibility of corn germ, hominy feed and wheat by-product were 79.0, 81.2 and 65.3%, respectively, digestible energy was 4189, 4372 and 2801 kcal/kg of dry matter, respectively, and metabolizable energy was 3910, 4351 and 2705 kcal/kg of dry matter, respectively.

Keywords : guinea pig; digestible energy; metabolizable energy; basal diet; ingredients.
