    Abstract:
    In a 28-d trial, 35 wethers weighing 35 to 60 kg were used to evaluate serum, liver, pancreas, kidney, diaphragm, heart, and neck muscle alpha-tocopherol concentrations after vitamin E administration as i.m. injections and(or) oral supplementation. Treatments (T) were as follows: 1) i.m. DL-alpha-tocopherol(DL-alpha-ol) d 1, 2) i.m. DL-alpha-tocopheryl acetate(DL-alpha-ac) d 1, 3) i.m. DL-alpha-ol d 1, 7, 14, and 21, 4) T 1 and oral supplementation, 5) T 3 and oral supplementation, 6) oral supplementation, and 7) control, no E supplementation. Supplemented wethers received 500 IU via injection and(or) 30 IU/kg of diet (acetate form). In a second 10-d trial, blood was periodically collected from 20 wethers weighing 32 to 47 kg that had been assigned to T as follows: 1) control, 2) i.m. DL-alpha-ol d 1, 3) i.m. DL-alpha-ac d 1, 4) T 2 d 1 and 7, and 5) T 3 d 1 and 7. Results from repeated measures ANOVA in both trials indicated that there were day x T effects (P < .0001) on serum alpha-tocopherol. Pretreatment serum tocopherol concentrations were .58 and .66 microgram/mL for Trials 1 and 2, respectively. In Trial 1, wethers receiving the four alcohol vitamin E forms showed a rapid increase in serum tocopherol between d 1 and 3, followed by a rapid decline to pretreatment concentrations for T 1, whereas T 3, 4, and 5 maintained higher than pretreatment concentrations after the decline.(ABSTRACT TRUNCATED AT 250 WORDS)
