On Feb. 8, 1954, a 4-year-old English Shepherd male dog was admitted to the Stange Memorial Clinic. The history revealed that two weeks previously the owner had noticed that the dog was sensitive in the flank area and over the sacral region. An examination at that time revealed that an elastrator band had been placed about the base of the scrotum at some time previously. When it became apparent that the scrotum was not going to slough the dog was referred to the clinic.
On Feb. 15, 1954, the cadaver of a 3-year-old female St. Bernard was admitted to Stange Memorial Clinic for diagnosis. There was a history of occasional straining and frequent scanty urination. The abdomen was greatly distended and before death the animal was quite depressed. The owner thought the animal was pregnant; however, there was no increase in mammary development. Since the animal was dead on arrival there was no clinical diagnosis made.
Agricultural Extension work was established in 1862 as a portion of the socalled Land Grant College Act. This act reads as follows: "In order to aid in diffusing among the people of the United States useful and practical information on subjects relating to agriculture and home economics, and to encourage the same, there may be continued or inaugurated, in connection with the college, agricultural extension work which shall be carried on in cooperation with the United States Department of Agriculture.
A black Angus steer was admitted to the Stange Memorial Clinic on March 3, 1954 with a history of weight loss. The animal had lost 200-300 pounds in five months while on full feed. There was swelling of the brisket . and the front legs, anorexia and considerable irritability upon handling. The temperature was normal and the animal showed no visible lesions. It was one of five animals in a herd showing similar symptoms. The ration consisted of clover and timothy hay cut the previous June, last season's ground whole corn, a commercial supplement and a salt and mineral mixture. A blood sample was citrated and sent to the chemistry department for vitamin A determination. The next day, March 6, the following results were returned: Vitamin A, 21.4 microgram per 100 cc. and carotene, 37.7 microgram per 100 cc. The normal value for vitamin A is 35 !1gm. per 100 cc. and the normal carotene value is 200 microgram per 100 cc. The reason for this deficiency while on the ration described is unknown. However, this condition has been diagnosed in a number of herds in a geographical area corresponding to the drouth area of 1953.
