          Abstract

          The mucosa of the rumen performs the functions of absorption, transportation, metabolism and protection, due to the presence of microorganisms in this compartment of the digestive tract, which are responsible for the digestion of approximately 60% of the organic material apparently digested. The histological structure and the histochemical profile of glicoconjugate of the mucosa of the stomach of sheep that were being fed with forrage cactus or palm (Giant Palm - Opuntia ficus indica Mil)1. Twelve sheep were used, with approximately 14 months old, which were oddly distributed in four diets: D1- 60.0% forrage palm + 40.0% concentrated ration; D2- 47.5% forrage palm + 12.5% elephant, napier grass + 40.0% concentrated ration, and D3 - 34,8% forrage palm + 25.2% elephant, napier grass + 40.0% concentrated ration and D4 - 60.0% elephant, napier grass + 40.0% concentrated ration. The experience period lasted 90 days, and, at the end, the animals were euthanized and fragments of different compartments of their stomachs were taken right after. The animals having consumed diets D1, D2 e D3 presented more developed papillas, while the ones of diet D4, presented less developed papillas. The stratum corneum of the epithelium of the rumen coating of the animals in diet D1 presented a slight erosion, when compared to those in diets D2, D3 and D4

Se analizó la estructura histológica y el perfil histoquímico de las estructuras de glicoconjugados de la mucosa del estómago de las ovejas que fueron alimentadas con forraje de cactus o palmeras (Giant Palm - Opuntia ficus indica Mil)1. Fueron utilizadas 12 ovejas, con aproximadamente 14 meses de edad, las cuales fueron distribuidas de manera impar en cuatro dietas: D1- 60.0% forraje de palmera + 40.0% ración concentrada; D2- 47.5% forraje de palmera + 12.5% hierba alta africana + 40.0% ración concentrada, y D3 - 34,8% forraje de palmera + 25.2% hierba alta africana + 40.0% ración concentrada y D4 - 60.0%hierba alta africana + 40.0% ración concentrada. La experiencia duró 90 días y al final, los animales fueron sacrificados y fragmentos de diferentes compartimientos de sus estómagos fueron directamente recogidos. Los animales que habían consumido dietas D1, D2 y D3 presentaron papilas más desarrolladas, mientras que los alimentados con dieta D4 presentaron papilas menos desarrolladas. El estrato córneo del epitelio del rumen de los animales de la dieta D1 presentaron pequeña erosión, cuando fueron comparados con los animales sometidos a las dietas D2, D3 y D4
