) is shown to be the fastest phytase in

the field. This has two benefits: the higher the speed, the higher the Phosphorous release from the phytate, and the less extra inorganic P needs to be added to the feed (resulting in a feed cost saving). Secondly, the faster phytate is destroyed, the faster its anti-nutritional properties will be eliminated. The reason why OptiPhos®

is the fastest phytase is based on

the PPS concept: pH profile, pepsine resistance and speed. Phytic acid must be in solution for the phytase to be able to hydrolyse the phosphate groups. Phytic acid is largely soluble at pH levels below 4.0, which is the pH of the gizzard or stomach of monogastric animals, but rather insoluble at higher pH values. OptiPhos®

is active in vivo in the upper digestive tract as it has

a pH optimum and flat profile at pH 2 to 4. In addition, OptiPhos® is resistant to pepsin, which is a protease produced in the gizzard/ stomach. Lastly, OptiPhos® (Vmax) of phytate.

Not only does poor digestion leave few nutrients available for also has a high speed of hydrolysis

growth, excess undigested protein and other nutrients work their way through the gut, allowing pathogens like E. coli, Clostridium, and Brachyspira to proliferate. So, what can we do to support early growth and digestion in

piglets? To start, we can provide exogenous enzymes to support digestion while the piglets’ own production is still limited. KEMZYME®

The outcome of this is that OptiPhos® has high P matrix

values, which are reliable and scientifically supported. The faster degradation of phytate will also lead to increased animal performance. This ‘superdosing effect’ is already observable at a double dose of OptiPhos®

incorporated 3 to 4 times the single dose. References available upon request.

same time, the pH of their stomachs is too high for efficient digestion, not reaching mature levels until almost 12 weeks of age.

For years, animal nutritionists have trusted Kemzyme to maximize the digestion of a wide variety of substrates. That’s even more critical today when high and volatile feed costs make flexibility critical to maintaining a cost-effective feed formulation. When you use Kemzyme, you know you have chosen a complete solution for complex substrates that ensures cost and performance fit together.

is a multi-enzyme with five quantified enzyme activities including both NSP-ases, protease and α-amylase. This combination of enzymes is perfectly designed to supplement the piglet, enabling better digestion and faster growth in the weeks immediately following weaning: across 4 scientific trials, the average reduction in FCR with KEMZYME Plus dry after weaning was 9 points, as shown in Figure 2, leading to an average return on investment of more than 10.

to support growth and performance. Kemin internal reference: TL-17-00057.

At weaning, the ability of young pigs to digest solid feed is severely reduced. They lack endogenous production of numerous crucial digestive enzymes, including amylase and lipase (Figure 1). At the
