Technical Bulletin 41: A feeding trial was conducted at the University of Minnesota, by Drs. Lee Johnston, Sam Baidoo and Jerry Shurson, to examine the effect of PorSol (DPS) on the performance of lactating sows and their litters.

Technical Bulletin 42: In a feeding trial conducted by a major United States feed company, pigs were fed diets containing DPS 50RD to evaluate the effects of replacing fishmeal or plasma on growth performance. Partial or entire replacement of spray-dried plasma protein with DPS 50RD in phase 2 starter diets did not significantly affect average daily gain, feed intake or feed/gain ratio. Although no significant differences between treatments were observed in phase 3, subsequent feed efficiency in phase 4 was significantly improved for pigs fed diets containing DPS 50RD. These observations suggest a positive carryover effect may exist for pigs fed DPS 50RD.

Technical Bulletin 43: DPS 50RD was used in a 5-week nursery trial to evaluate its effectiveness on growth performance of pigs weaned at 20 days of age. Dr. Hans Stein conducted this trial at South Dakota State University (SDSU). Pigs fed diets containing 3.0 or 4.5% DPS 50RD had significantly higher (P<.05) weight gain and gain/feed than pigs fed the 5.0% fishmeal control, days 7-21. No significant increases in feed intake were observed, days 7-21. Therefore, these results suggest an improvement in gut health and perhaps nutrient uptake occurring in pigs fed DPS 50RD.

Technical Bulletin 50: A research trial was conducted in April, 1999 by Dr. Cheng Ji at Agriculture University of China to examine:
1. The effects of DPS vs. other high quality proteins (fishmeal and plasma) on young pig performance.

Technical Bulletin 51: Results show that the competitive sample contains 50-60% soybean protein carrier. DPS 50RD only contained 3-4% soybean protein carrier. This results in the competitive sample containing 40-50% peptone when compared to DPS 50RD at 96-97%. The price difference between the two products is clearly negated by the peptone/carrier concentrations.
