RESUMO
Various nutritious nutritional-supplement gels are being marketed for use in veterinary medicine. This study was designed to determine whether serum calcium, phosphorous, or magnesium concentrations were different between cows given a gel containing calcium chloride as its active ingredient (treated) and cows given inert carrier gel (control). The study revealed a significant (P < 0.01) increase in serum total calcium concentration within 5 minutes of administration of a calcium gel given to cows within 1 hour of parturition. Serum total calcium concentration had returned to baseline value by 24 hours after calcium gel administration. Serum inorganic phosphorus concentration also increased significantly (P < 0.05) after treatment. Significant changes in serum magnesium concentrations were not detected.

A tumor was removed from the nose of a 4-year-old Holstein. Hemangiosarcoma was diagnosed on histologic examination. Redevelopment of the tumor necessitated a second surgery. Routine CBC and serum biochemical analysis were normal. Clinical signs of metastasis were not reported by the owner during the next 13 months before the cow was sold for slaughter.

L-asparaginase was used to treat a 4-year-old Holstein cow with lymphosarcoma that involved the spinal cord, subiliac lymph nodes, and retrobulbar space. The cow received 60,000 IU of L-asparaginase IV for a total of 4 treatments. After each treatment, the cow's condition improved, characterized by decreased weakness, decreased ataxia, a reduction in size of the left subiliac lymph node, and decreased exophthalmos. Side effects were not observed. The cow was kept alive for 57 days. This treatment offers a way of salvaging the genetic potential of valuable cows and bulls.
