Simplified Procedure for Abomasal Cannulation in Rumen Fistulated Goats and Sheep

Abstract

To facilitate the infusion of nutrients into the abomasum of small ruminants, an abomasal cannulation technique was developed that would allow placement through a rumen fistula. Location of the cannula was confirmed by slaughter of two wether lambs. A retaining device was developed that resisted the tendency of movement of digesta in the rumen to twist the infusion line and pull the cannula through the reticulo-omasal orifice into the reticulo-rumen. The abomasal cannula was tested for 45 days in lactating dairy goats, and all cannulae remained functional and in proper position. © 1982, American Dairy Science Association. All rights reserved.
