A case similar to the above came under our notice a few months since. A cow, of a superior breed, was sent a few miles into the country to winter. Having always had the very best of feed, the owner gave particular instructions that she should be fed accordingly; instead of which, however, she was fed on foxgrass and other indigestible matter, in consequence of which she was attacked with acute indigestion, (gastric fever, as it is generally called,) more popularly known, in barn-yard language, as a "stoppage." A man professing to understand _cow-doctoring_ was sent for, who, after administering "every thing he could think of" without success, gave a mixture of hog's lard and castor oil. When asked what indication he expected to fulfil, he replied, "My object was to wake up the cow's ideas"! Unfortunately, he awoke the wrong ideas; for the cow died. On making a post mortem examination, about half a bushel of partly-masticated foxgrass was found in the paunch, and the manyplus was distended beyond its physiological capacity. On making an incision into it, the partly-digested food was quite hard and dry, and the mucous covering of the laminæ--even the laminæ themselves--could be detached with the slightest force. The farmer will probably inquire, What ought to be done in such cases? Before we answer the question, a few remarks on the nature of the obstruction seem to be necessary. In the article _Description of the Organs of Digestion_, the reader will learn the modes by which the food reaches the different compartments of the stomach. In reference to the above case, the causes of derangement are self-evident, which will be seen as we proceed. The animal had, previous to the journey, (thirty miles,) received the greatest care and attention; in short, she had been petted. Being pregnant at the time, the stomach was more susceptible to derangement than at any other time. The long journey could not act otherwise than unfavorably: first, because it would fatigue the muscular system; secondly, because it would irritate the nervous. Here, then, are the first causes; and it is important, in all cases of a deviation from health, to ascertain, as near as possible, the causes, and remove them. _This is considered the first step towards a cure._ If we cannot remove the causes, we are enabled, by an inquiry into them, to adopt the most efficient means for the recovery of the animal. The animal having had a bountiful meal before starting on the journey, and not being allowed sufficient time to remasticate, (rumination is partially or totally suspended during active exercise,) probably, combined with the above causes, an acute attack of the stomach set in--subsided after a few days, and left those organs in a debilitated state. The sudden change in diet also acted unfavorably, especially as the foxgrass required more than ordinary gastric power to reduce it to a pulpy mass, fit to enter the fourth, or true digestive stomach.
