DISEASES OF DOMESTIC ANIMALS 591 



fold of fetlock. Lameness ensues. Chin, cheeks, gums, roof of mouth, feet, 

 penis, vulva, udder, may be attacked by necrotic process. 



2. In lambs. Sudden swelling of lips, warty patches or fissured crusts 

 on lip and muzzle with suppurating ulcers underneath. Necrotic areas at 

 corner of mouth. Usually heal in time. 



8. Venereal. Angry ulcerating sheath, and penis sometimes swollen and 

 ulcerated. In ewes ulceration about perineum, vulva, and anus. 



4. Foot rot. Ulceration about cleft and claw with foul, purulent dis- 

 charge. 



Prevention. Isolate newly-bought animals for 2 weeks and frequent ex- 

 amination of exposed with segregation of sick. Disinfect infected premises, 

 remove manure and surface soil from corrals and disinfect with saturated 

 chlorinated lime solution. Transfer healthy sheep to new pastures and bed 

 grounds. Frost kills bacteria in pastures. 



Scrape oil crusts and scabs with sharp stick and apply cresol, 6 parts; 

 sulphur, 10; and lard, 100. Apply thrice weekly to ulcerations nitric acid 

 (1 to 70), after removing scabs, and follow with ointment as aljove. In foot 

 cases same treatment or drive sheep through 5% cresol solution thrice weekly. 

 Venereal lesions clip wool and apply lysol solution (2%) daily and stimulate 

 occasionally with nitric acid solution. On warty lips in lambs, use 5% 

 cresol ointment and swab sore mouths with 2% potassium chlorate. Resistant 

 cases killed. Dip sheep in 5 per cent, cresol solution before returning to flock. 



LiTHiAsis. See Calculi. 



Liver Rot in Sheep. (Occasionally in cattle.) 



Due to Distomum hepaticum and other species of Distomata or fluke 

 worms; Order, Trematoda. Aspidium and kamala have both been found to 

 effect cures. Give concentrated, dry food with plenty of salt. Avoid over- 

 stocking pastures or give up pastures, if seriously infested. Sprinkle lime 

 and salt or copperas (250 to 400 lbs. to the acre) on pastures from May to 

 August. Drain pastures to destroy snails, the intermediary host of the dis- 

 tomata. Diseased animals should be slaughtered and their livers burned. 

 Keep sound sheep away from infested pastures. Disinfect manure of infested 

 animals with quick lime. 



LouPiNG III in Sheep. 



Due to bacteria conveyed by ticks living in tall grass and damp spots. 

 No cure; treatment wholly preventive. Isolate and kill diseased sheep. Dip 

 the rest of flock as for scab. Wet pastures avoided or drained. Long grass 

 and rushes must be avoided. 



Luxations. See Dislocations. 



Lymphangitis. Cellulitis. Inflammatory Edema. 



Idiopathic in horse in hind legs. Apply from the beginning hot compresses 

 of 2 per cent, lysol or creolin solution, covered with waterproof protective 

 and bandage, to whole limb; change frequently. Give aloes, 3iv, calomel, 5i, 

 in ball, and light diet — mashes, green food and hay. Enforce absolute rest. 

 Tincture of aconite and spirit of nitrous ether may be used for fever every 

 two hours, but local treatment most useful. Alcohol and milk in debilitated 

 subjects. When acute symptoms subside, use dry bandaging, friction with 

 oil of turpentine and sweet oil (equal parts), and gentle exercise to reduce 

 swelling of limb. Internally, potassium iodide may be given to hasten reso- 

 lution, together with laxatives to remove water from the system, as artificial 

 Carlsbad salt on the food. ' 



Lymphangitis, Mycotic or Epizootic, of Horses. 



JExcise or remove limited area of diseased lymphatics with actual cautery 

 and knife. Incise, curette and cauterize abscess cavities with Paquelin 

 cautery. Isolate diseased animals and disinfect harness, contaminated objects 

 and premises contaminated by affected animals. 



Lymphatics, Inflamed. See Glandular Enlargements. 



Maggots From Flyblow. 



Apply kerosene, or turpentine and oil. Other antiseptics.
