Cause.—Due to a septic infection taken into the blood, frequently found in cows with retained afterbirths, following inflammation of the womb or intestines, wounds and bruises of the skin and frequently found in calves affected with Joint Ill.

Symptoms.—High temperature 103° to 107°F., pulse rapid and feeble, breathing increased, grinding of the teeth, the animal refusing to eat in most cases and ceasing to chew the cud, although there may be great thirst present. Abscesses may form in various parts of the body, the membranes of the eyes and mouth will be injected with blood, giving them a dark red appearance, although in the latter stages of Blood Poison this may change to a yellowish tinge. Constipation or Diarrhoea may be connected with the disease. The animal dies by general emaciation from four to six days after the first symptoms are noticed.

Treatment.—Unsuccessful, as when the infection once becomes absorbed in the blood it is always certain that death will follow. If due to injuries or wounds, wash them with Bichloride solution, one part to one thousand parts of water, but if due to retained afterbirth or inflammation of the womb, inject one gallon of distilled water containing five per cent Carbolic Acid. If in young calves, treat the same as under the heading of Joint Ill. If due to inflammation of the intestines, give Hyposulphite of Soda, two ounces; Potassi Iodide, one dram, two or three times a day in their drinking water. When abscesses form, lance them with a clean, sharp knife. If the animal is constipated, place two drams of Aloin, two drams of Pulv. Gentian Root in a capsule and give with capsule gun. If Diarrhoea is present, give Gum Catechu, two drams; Protan, three drams; Zinc Sulphocarbolates, one grain. Place in gelatin capsule and give with capsule gun. Feed warm wheat bran mashes, steamed rolled oats, vegetables and green grass, if possible.
