Abstract
Responses to prepartum injection of sows with Se and vitamin E (E) were evaluated by determining immunoglobulin (IgA, IgM, IgG) levels in the colostrum and serum of the sows and the serum of their offspring. Fifty-four sows (40 multiparous, 14 primiparous) receiving diets adequate in E and Se according to current NRC (1988) standards were randomly allotted to four treatment groups in which a single i.m. injection of saline (controls), 5 mg of Se, 1,000 IU of E, or both Se and E were given on d 100 of gestation. Sows were bled prior to and 7 d after injection, at farrowing and on d 14 and 28 of lactation. Colostral samples were collected at the initiation of farrowing. Pigs were bled 20 h postpartum and at 14 and 28 d of age. Major immunoglobulin changes in the serum of the sows due to treatment were not seen prior to parturition. Injections of Se and(or) E resulted in higher colostral IgM levels (8.4, 10.7, 9.8 and 9.6 mg/ml, respectively), but only the response from Se was significant (P < .05). Concentrations of colostral IgA or IgG were not affected by treatment (P > .30). Compared with controls, all three treatments increased (P < .10) IgM concentrations in serum from pigs at birth (28.3, 33.3, 36.0 and 33.5 mg/ml, respectively), whereas IgA and IgG concentrations were not affected (P > .30). On d 14, IgM concentrations in pig serum from the sows treated with Se and Se + E remained elevated (10.2, 13.4, 12.3 and 12.9 mg/ml, P < .05), whereas all three treatments increased IgG concentrations (2.1, 3.0, 3.1 and 3.6 mg/ml, respectively). These results indicate that prepartum injection of sows with E and Se influences immunoglobulin transfer to their progeny. Copyright © 1989. American Society of Animal Science .
