Surgical techniques for ruminotomy with ruminal fistulationin goats

Abstract

This work was part of the research project Nutritional Quality, Ruminal Degradability and Fecal Digestibility of Moringa oleifera. Male goats were criollo from 24 to 36 months, average weight 35kg, evaluated clinically without presenting pathological symptoms. Prior to surgery, goats were subjected to fasting of solids and liquids, in the pre-operative phase, Meloxican, Penicillin G Procaine, acepromazine and Ketamine were used, as well as a regional sedation with cranial epidural and left paravertebral nerve blocks T13, L1 , L2 with 2% lidocaine. The ruminotomy is the opening of the rumen where two techniques of ruminal fistulation were applied, in both the left lateral cube animal was placed to incisid in the area of ​​the ijar, overcome the subcutaneous plane by dissecting the fibers of the external oblique, internal and external abdominal muscles. the transverse abdominal, peritoneum to then expose the rumen and incise in it and place the ruminal fistula fixing it with a purse string to insert it into the abdominal cavity in both techniques. In the first, the rumen, the peritoneum and the aforementioned muscles were joined with suture threads for subsequent closure of the skin. In the second technique, only the muscles were allowed to retract to their initial position finally, subcutaneous approach and skin suture with nylon

thread was made. Seven days after surgery it was determined that the healing and adherence processes of the muscles and the rumen were similar in both techniques.
