Promotes digestive health of piglets


Strengthens intestinal microflora


Costs only pennies a day to feed

MSP[RS] is unique in that it can be effectively used at many critical times to aid the piglet in intestinal health — at birth, at weaning, nursery weeks 1-3, and lactating sows.

MSP[RS] Resistant Starch provides fuel for improved gut health in swine operations. Its ease-of-use from birth onward assist the piglet with developing a healthier, more resilient colon. MSP[RS] Resistant Starch has been proven to lower fecal pH and improve fecal consistency. Resistant Starch is classified as a prebiotic: it passes intact through the stomach and small intestine of monogastric animals into the large intestine where it is fermented into short-chain fatty acids, providing a reduction in pH and fueling the growth of colonocytes.



#1 Reducing scours and evening out litter weights.

#2 Ease of use.

#3 Costs only pennies per piglet per day!




Young piglets have underdeveloped microflora in the large intestine and are very susceptible to pathogens. An early start with MSP[RS] has immediate benefits in terms of disease resistance.

Resistant Starch fermentation produces short-chain fatty acids, particularly butyrates.

Resistant Starch Produces Short Chain Fatty Acids, Particularly Butyrates

In scientific studies, the consumption of resistant starch has been proven to effect fermentation in the colon, altering the colonic concentration of short chain fatty acids and resulting in a higher concentration of butyric acid. Studies were completed using 10-week old pigs with in-vitro fermentation in hind gut. Resistant starch fermentation produced the highest butyrate levels with P < 0.001 at 48 hours of fermentation.

Short-chain fatty acids lower digestive tract pH levels.

Short Chain Fatty Acids Lower pH

MSP[RS] Resistant Starch has been proven to reduce fecal pH through actions of increased production of short chain fatty acids. Studies using MSP[RS] in nursery pigs at 0.5 and 1.0% in diets resulted in lower Ileum and Caecum pH at P < 0.01.

Butyrates create a healthier colonic epithelium.

Butyrates Create Healthier Epithelium

Butyrate is widely accepted as the preferred fuel for colonocytes. Consumption of resistant starch and the resulting increase in butyrate content results in a heavier digestive system, specifically, the colon, improved proliferation and inhibits apoptosis of epithelial cells. Crypt depth in the colon has also been shown to increase in pigs fed diets containing resistant starch.

Pathogenic bacteria growth inhibited.

Inhibits the Growth of Pathogenic Bacteria

Studies have shown that resistant starch in the feed supports the growth of certain indigenous bacterial population groups, particularly acidogenic bacteria such as Bibidobacterium and Lactobacilus. Similarly, studies have shown a reduction in eColi bacteria with resistant starch. The reduction in pH contributes to the health of one organism and decline in the other.

Water absorption increased.

Increases Water Absorption

Healthy caecum and ileum epithelium provide increased surface area allowing for higher levels of water absorption. In small intestine infections with coronaviruses such as TGE or PED, the small intestine is producing excess water, causing critical nutrients to be flushed through the large intestine. Use of MSP[RS] Resistant Starch from day one creates a healthier epithelium and provides infected piglets with increased disease tolerance.

Mineral absorption increased.

Increases Mineral Absorption

Soluble minerals are absorbed with water through the colon to provide essential nutrients. High levels of water absorption in the caecum and ileum increase the piglet’s ability to absorb minerals, particularly in disease situations.

Effective use in swine operations

To maximize the efficacy of MSP[RS] Resistant Starch, we’ve prepared this application guide for farmers, veterinarians, and agricultural technologists working with swine herds. We cover the farrowing room at birth, introduction of creep feed, in the nursery, in the sow herd, and pre-shipping considerations.

Effect of supplemental diet containing MSP[RS] Resistant Starch on weaned pig performance…

This University of Manitoba research summary looks at the effect of supplemental diet containing MSP[RS] Resistant Starch on weaned pig performance, fecal consistency, and gastrointestinal tract characteristics. The objective was to determine and quantify the effects of MSP[RS] on weanling pig performance and to further examine the effects of MSP[RS] on the incidence of Post Weaning Diarrhea (PWD) and subsequent gastrointestinal characteristics. For more information and a complete copy of the study, contact The study was recently approved for publishing in the Journal of Animal Science. MSP[RS] Resistant Starch was the product used in the study, demonstrating effectiveness at 0.5% and 1.0%.
