Abstract:
A production experiment was conducted with 96 fourteen-day-old weaned male piglets to compare diets containing preparations of freeze-dried porcine plasma (P) and freeze-dried bovine colostrum (C) for 35 days after weaning.

The levels of colostrum and porcine plasma were reduced from 60 g/kg to 25 g/kg after the first week of weaning. There were no effects of diet on performance in the first 4 days after weaning. However, between 18 and 21 days of age, pigs fed the SP diet ate less (
