Fistulación y canulación permanente del compartimento 1 (Rumen) en Llamas (Lama glama)

Rumenostomia com colocação de cânula flexível em ovinos

“…No presente trabalho, a flexibilidade da cânula de borracha permitiu uma excelente adaptação na rumenostomia em ovinos, o que está de acordo com o observado em estudo com cânulas semelhantes em lhamas [2].…”

Técnica alternativa de fijación por planos quirúrgicos para colocación de cánulas ruminales en ovinos

“…La utilización de cánulas ruminales es una ayuda importante para la evaluación nutritiva de los alimentos, la determinación de la eficiencia fermentativa del rumen, y en la respuesta fisiológica del órgano a variaciones dietarias (Cabrera et al, 2000;Crowley et al, 2011). Crowley et al (2011), propusieron una técnica de rumenotomía e inmediata colocación de fístula ruminal, diferente a las descritas en la bibliografía, ya que manejaron otro tipo de material, además de la forma de fijación por planos quirúrgicos.…”

Description of surgical technique in rabbit cannulation for obtaining cecal content

“…In the majority of domestic animals several fistulae and cannula placement techniques have been developed that are adequate for the purpose of placing or extracting samples and carry out several types of evaluations. Nevertheless, in the case of rabbits the description of this procedures are few and incomplete (Carman and Waynforth 1984, Cabrera et al 2000, Parker and McMillan 1976, Gidenne 1992, Jehl and Gidenne 1996, Gidenne et al 1998. Even though there has been reports of cannulation in the cecum and 13th cecal loop (Hernández andCobos 2001, Blas et al 2003), currently there is no information on the cannulation technique and effectiveness of the cannulas to obtain and evaluate cecal content in vivo.…”

“…Placement of cannulae at the cecal level allows direct studies on the microflora present in the cecum and on the fermentation that is carried out by these microorganisms. It also allows the evaluation of the production of several metabolites such as ammonia and volatile fatty acids (that are produced and absorbed in the cecum), as well as the presence of vitamins and the pH changes generated by the various components of the diet (Cabrera et al 2000).…”
