The effect of dietary spray-dried bovine colostrum and plasma on the response of pigs to enterotoxigenic E. coli challenge after weaning

Twenty four, 21-d-old female pigs were fed diets containing either skim milk powder (CON+), spray-dried bovine colostrum (7.5%, BC+) or spray-dried bovine plasma (7.5%, BP+) and were dosed orally with 1 × 10 9 CFU of E. coli O149:K88. Another group of 8 unchallenged pigs was fed the skim milk powder...

Description
Summary:Twenty four, 21-d-old female pigs were fed diets containing either skim milk powder (CON+), spray-dried bovine colostrum (7.5%, BC+) or spray-dried bovine plasma (7.5%, BP+) and were dosed orally with 1 × 10 9 CFU of E. coli O149:K88. Another group of 8 unchallenged pigs was fed the skim milk powder diet (CON−). On d 19 of the experiment all piglets were euthanased. Adverse effects of the E. coli challenge were observed variously throughout the small intestine in pigs consuming either the BC+ or BP+ diets. In this experiment, similar responses to the E. coli challenge were observed in both plasma and colostrum fed pigs, which suggests that spray-dried bovine colostrum may be a potential alternative to spray-dried bovine plasma.
