DPS® is the world´s leading animal-based peptide for inclusion in young animal diets as a functional, high-quality source of amino acids. It is the co-product of enzymatic hydrolysis of porcine intestinal mucosa for the production of heparin in the human pharmaceutical industry. After hydrolysis and heparin extraction, the liquid protein is concentrated and gently dried.
A functional peptide is a protein ingredient that provides a specific value added benefit beyond supplying digestible amino acids to the diet.
Research has shown that besides being a high-quality peptide source, DPS stimulates gut development in young pigs. In a trial comparing DPS to fishmeal and plasma, piglets fed DPS had equal villus height: crypt depth measurements as pigs fed plasma and significantly better than piglets fed high-quality fishmeal.
DPS has been used in lactating sow diets, poultry diets, aquaculture, and canine diets.

UltraMannan is a high quality source of beta glucans and complex mannans from primary food grade grown yeast. Research has shown that the inclusion of complex mannans in piglet, sow and poultry diets improves gut health by preventing colonization of harmful microorganisms. Laboratory analyses indicate that UltraMannan contains 20% more complex mannans than the major competitor’s product. Research also indicates that UltraMannan out-performs the leading competitor’s product.

Technical Bulletin 27: DPS 30 had similar overall performance when compared to spray dried plasma protein (SDPP) in SEW diets and spray dried blood meal (SDBM) in Phase 1 diets. However, the DPS 30 diets had a lower cost of gain compared to spray dried plasma protein and spray dried blood meal diets.
Technical Bulletin 28: DPS 30 was an effective replacement for select menhaden fish meal (SMFM) in phase 1 swine nursery diets. A new more concentrated DPS product, DPS 50RD, was also tested.
Technical Bulletin 29: The inclusion of 3% DPS 50RD (45% crude protein) significantly increased feed intake and daily gain by 5-12% depending on the ingredients of the control diet.
Technical Bulletin 30: Pigs fed diets with 5% DPS 30 consumed more feed, grew faster and had significantly reduced diarrhea scores.
Technical Bulletin 31: DPS 50RD and DPS 30 treatments had similar ADG, ADFI and F/G at week 5 to the Plasma protein treatments and better performance than the Fishmeal control diet. There was a high correlation between diarrhea index (DI) and performance with DPS and plasma having significantly lower DI than the control.
Technical Bulletin 32: Examining the digestive enzyme activity and intestinal morphology of nursery pigs receiving various proteins (fishmeal, DPS and plasma). There was no significant difference in enzyme activity among various proteins. DPS and plasma did stimulate villus growth and crypt cell development of nursery pigs.
Technical Bulletin 33: DPS is a digested protein, it has the double biosecurity benefit of high processing temperatures and proteolytic enzyme treatment. It is highly unlikely that any viruses can survive the DPS production.
Technical Bulletin 34: Pigs preferred a diet containing flavored DPS versus a diet with non-flavored DPS.
Technical Bulletin 35: Determining the effect of adding two levels of flavoring (low and high level) to Dried PorSol 50RD (DPS 50RD). There was no indication that the higher level of flavoring increased the preference exhibited by the pigs.
Technical Bulletin 36: Dogs showed a numerical preference for a ration with 2% CPS 21 added. In the second trial dogs significantly preferred a ration with 2% CPS Ultra 21 added.

Technical Bulletin 38: The Japanese government conducted several tests to determine the digestibility and availability of nutrients in DPS for pigs. These results showed that DPS is a highly digestible product for swine.
Technical Bulletin 39: A trial was conducted at the University of Idaho by Dr. Ronald Hardy to determine the apparent digestibility coefficient (ADC) of DPS for rainbow trout. It was determined that DPS 45SD is highly digestible and could serve a vital purpose in fish feed applications.
Technical Bulletin 40: A canine palatability test was conducted at Kennelwood Inc. Champaign, IL in March 2000 to examine dog preferences for Condensed PorSol Ultra (CPS Ultra) versus a pork liver digest (PLD) product. Dogs showed equal preference for diets spray coated with PLD or CPS Ultra.
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. Sows fed diets with DPS 30 during lactation had a linear increase in ADFI versus the control sows receiving no DPS 30.
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 45: In a study conducted by 1DeRouchery et al at Kansas State University, commercially available specialty protein products were evaluated in a 14-day growth assay with 20 day-old pigs.
Technical Bulletin 48: A 5-week study was conducted by Dr. Hans Stein of the University of Illinois to evaluate the effects of dietary mannan products on the growth performance of 20 day-old weanling pigs.
Diets supplemented with UltraMannan 120 and UltraMannan 85 significantly improved piglet growth performance compared to pigs fed diets containing the competitor’s mannan product (Mannan B).
Technical Bulletin 49: A 35-day, phase 2 nursery trial was conducted at Kansas State University, by Dr. Joel DeRouchey et al. to evaluate the growth performance effects of including DPS 52 in the diets of 15 to 25 lb. pigs. In this study piglets receiving diets containing DPS 52 had significantly improved ADG and feed efficiency, day 0-14 compared to piglets fed fishmeal.
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.
2. The digestive enzyme activity and intestinal morphology of nursery pigs receiving various proteins (DPS, fishmeal and plasma).
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.
