Humeral or femoral fractures in 4 adult bullocks were successfully repaired with Kuntschner clover leaf nails. Animals responded favorably to surgery and physiotherapy, including massage and planned exercise. Follow-up for 1 year revealed near-normal gait and restored utility. The significance of postoperative management, especially of physiotherapy, is stressed.

Experimental uremia created by obstructing the urethra of 7 cross-bred bulls was associated with significant (P less than 0.05) increases in PCV, blood urea nitrogen concentration, arterial and venous pH and PCO2, arterial bicarbonate, and base excess. Total serum protein concentration decreased nonsignificantly. Arterial PO2 reduced significantly during later stages of uremia. Arterial and venous oxygen saturation, arteriovenous oxygen difference, oxygen extraction ratio, and arteriovenous pH difference were not affected significantly. Uremia was characterized by progressive metabolic alkalosis with, as a compensation, hypercapnia, and arterial hypoxemia. There was no evidence of systemic shunting of blood except in 1 animal.

Two rare cases of internal herenia in bovines (Bubalus bubalis), in which reticulum and abomasum had herniated into the thoracic cavity, were successfully treated. Involvement of abomasum did not exhibit any additional symptoms other than those commonly observed in cases where only reticulum is herniated. The term diaphragmatic hernia has been considered appropriate for this condition by the present authors.
