A study was conducted to evaluate the efficacy of various injectable forms of vitamin E on the transfer of sow vitamin E to colostrum and milks. Twenty multiparous sows were injected intramuscularly with d-α-tocopherol, dl-α-tocopherol and d-α-tocopheryl acetate at 8.8 ㎎/㎏ body weight at 100 ant 107 day postcoitum. A saline injected group served as the control. Colostrum and milk samples were collected manually and two pigs per litter were bled with serum saved for tocopherol analysis at 7 and 21 day of age. Sow reproductive performance and subsequent litter response were similar among treatment groups. Sows injected with the vitamin E products had higher (P$lt;.05) serum tocopherol levels than the control group after 1 week of first injection (107 day postcoitum). Colostrum from the sows injected vitamin E products contained about 3 times more α-tocopherol dean the control group. Alpha-tocopherol levels diclined from colostrum to 7 day milk. Only tje d-α-tocopherol injection group had higher 7 day milk tocopherol contents than the other groups, with no difference in 21 day milk for all groups. Pigs from vitamin E injected sows had higher serum α-tocopherol concentrations than the control sow group at 7 day but not at 21 days of age.
