The effects of daily supplementation of 1000 IU of either d-α-tocopherol acetate or dl-α-tocopherol acetate to Holstein cows from drying off to 8 wk post-partum on plasma creatine kinase and selenium levels in plasma and red blood cells were studied. Supplementation with either d-α-tocopherol acetate or dl-α-tocopherol acetate showed no effect on selenium levels in both plasma and red blood cells. However, supplementation with d-α-tocopherol acetate, but not dl-α-tocopherol acetate decreased plasma creatine kinase significantly (P < 0.05) prior to parturition. Key words: Vitamin E, creatine kinase, selenium

A procedure was developed for the rapid analysis of vitamin E in bovine ruminal fluid. α-Tocopherol acetate (20 ppm) was not degraded in vitro nor was there evidence of ester hydrolysis when it was incubated for 24 h in ruminal fluid from cattle fed three forage diets.

Key Words Vitamin E

Twenty-four mid-lactation Holstein cows of mixed parity were used in a 2 × 2 factorial design to examine the effects of vitamin E and Se supplementation on performance, levels of anti-oxidants in milk and resistance of milk to oxidation. Only a proportion of cows (25%) produced milk susceptible to oxidation; however, there was a trend (P = 0.11) toward reduced oxidized flavor when vitamin E was given. Milk production was increased when either vitamin E or Se were given alone (P = 0.056). Supplementation with 8000 IU dl-α-tocopheryl acetate d−1 approximately doubled α-tocopherol concentration in blood and milk (P < 0.001). Se supplementation with Se-enriched yeast at 5 mg d−1 increased Se levels in milk from 13.2 to 34.7 μg L−1 (P < 0.001). Key words: Vitamin E, tocopherol, selenium, milk, oxidized flavor, cow

A 32-year-old male presents with diffuse myalgias, weakness, and dark urine for 1 day. The patient states he recently started a new exercise program. He is hemodynamically stable, and his physical examination reveals diffuse muscle tenderness. His creatine kinase (CK) returns at 8,000 international units per liter (IU/L), and his urinalysis reveals blood but only three red blood cells (RBCs) on microscopy.

Eighty crossbred beef steers weighing an average of 493.4 ± 3.2 kg were allocated to five treatment groups of 0, 12, 24, 36 or 48 h off feed and water in order to examine the effects on selective blood metabolites. Progressive increases (P = 0.01) were observed in serum chloride, red blood cells, hemoglobin and hematocrit simultaneously with reductions in serum glucose and, by implication, plasma volume. Changes were most noticeable between 24 and 36 h off feed and water. Key words: Cattle, fasting, metabolites, carcass
