Effects of specialty proteins as alternatives to bovine or porcine spray-dried plasma in non-medicated diets fed to weaned pigs housed in an unsanitary environment

The average daily gain at d 7 post-weaning for each pen per dietary treatment is presented in Fig. 1 as an ob- Translate basic science to industry innovation servation of the impact of the experimental conditions of unsanitary pens and non-use of medications on pig growth. None of the pens fed SDPP diets had a negative ADG at d 7 and the minimum ADG for SDPP diets was 58 g. Three of 11 pens provided SPC and 2 of 11 pens provided each of the APP diets had negative ADG results at d 7. However, for all non-SDPP diets, there were some pens that had ADG results within the minimum range of the SDPP diets. The conditions of unsanitary pens and non-use of medications apparently affected variation in pen ADG results; however, the results by dietary treatment were not likely strictly influenced by pen environment because dietary treatments were randomly allotted to pens within weaning group and by BW group.
