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

Translate basic science to industry innovation As done for Exp. 1, the ADG at d 7 for each pen by dietary treatment for Exp. 2 is presented in Fig. 2 . Pens provided the SDBP diet had a minimum and maximum ADG result of 39 and 144 g, respectively. However, all pens fed non-SDBP diets had at least 1 negative ADG result. Maximum ADG results ranged from 69 to 122 g for non-SDBP treatments. As in Exp. 1, the experimental conditions of unsanitary pens and non-medication likely affected variation in pen results in Exp. 2, but response to dietary treatments was probably not strictly related to chance of pen location because dietary treatments were randomly allotted to pens within weaning group and by BW group.
