EFFECTS OF VITAMIN-E INJECTION ON BODY-TEMPERATURE AND PLASMA ALPHA-TOCOPHEROL CONCENTRATIONS IN PIGS, LAMBS AND CALVES

Fifteen pigs, 15 lambs, and 15 calves were used to study the effect of supplementation of vitamin E on body temperature and plasma alpha-toc opherol concentrations following 1 intramuscular injection in 3 doses (1x, 3x, 5x). The 1x doses for pig, lamb, and calf were 500, 1 000, an d 1 500 IU, respectively. Data on body temperature and plasma alpha-to copherol concentration were analyzed by least-squares procedures separ ately for each species. In each species plasma alpha-tocopherol concen tration increased with increase in the dose of vitamin E injection, hi ghest on d 1 postinjection and declined slowly throughout the remainin g observation period. There was a transient elevation of body temperat ure on d 1 and 2 after injection in all species.
