=STRINGHALT IN HORSES.=--Stringhalt is an involuntary contraction of the muscles that bring the hind leg or legs forward. The cause of stringhalt is a deranged condition of the nerves supplying the muscles, causing the leg or legs to be brought up with a jerk. In slight cases of stringhalt it is necessary sometimes to turn the animal round from right to left, and from left to right, in order to make him show signs of stringhalt, the symptoms of the disease being exhibited as he turns one way only. This disease sometimes comes on suddenly, but generally develops slowly. It is an unsoundness, and depreciates the animal’s value and makes him unfit for hard work or fast driving. There is no sure cure for stringhalt; the animal can sometimes be relieved by giving him one ounce bromide of potassium at a dose twice a day in bran mash, and continuing it for one week, then skipping a week and giving again. It can sometimes be relieved by cutting the tendon or tendons of the affected muscles, but the operation should be performed by a qualified veterinarian. =SUNSTROKE.=--See Heat Exhaustion and Sunstroke. =SWAMP FEVER.=--This disease, by some called infectious anemia of horses, is produced by an invisible organism, which is transmissible to horses, mules, and asses. About the first symptoms noticed are a general weakness of the animal; it tires very easily and is not able to do any work. The loss of flesh is apparent in spite of the voracious appetite which the animal has at times. The appetite usually remains good until death, but the feed seems to do the animal no good. The temperature is very irregular. Some days it runs quite high, at times to 107°; again it is below normal. An animal may have several attacks of the trouble, but each succeeding attack seems to be more severe. The blood becomes thin, and the circulation impaired, and frequently there appears a swelling under the chest or abdomen, or an enlargement of one or more legs. It is quite easy to recognize the trouble, especially in the advanced stages. The slow progress at the beginning, remittent fever, progressive emaciation and anemia, unimpaired or ravenous appetite, staggering gait, and excessive urination are usually all present to a greater or less degree. Recovery takes place only when treatment is begun early and when the disease is not too acute.
