DUODENAL AND ILEUM CANNULATION IN CATTLE

Abstract

Anoperation for fixing cannulae made of silicone at proximal duodenum and terminal ileum was conducted in 4 crossbred Native X Holstein Friesian cattles. A routine right flank laparatomy was done. The intestinal wall at the required positions were exteriorised and longitudinal incisions were made for seating the cannulae into the intestine followed by twice purse - string sature. Another stab - wound incision was made at the lower part behind the first incision for inserting the cannulae through out off the flank. The cannulae were fitted with body by siliconering. After the operation, the cannulae removed from the intestine before the intestinal wall and the skin were adhered completely. Therefore, another operation for fixing the removed cannulae was conducted and resulted in an adherent of the intestinal wall and the skin after 8 weeks of the operation and also an extra care was taken into the last procedure. Intestinal cannula made of silicone can be easily inserted and replaced without an adverse effect to the animals. The experimental cattles have been using for many experiments with normal growth and reproduction.
