Many feed ingredients are not fully digested by animals. However, by adding enzymes to feed, the digestibility of these components can be enhanced. Enzymes are now well-proven and successful catalysts that allow feed producers to extend the range of raw materials used and improve the efficiency of existing formulations. KEMZYME™ MAP Dry is a stabilized multi-enzyme formulation developed by Kemin to improve the digestibility of raw materials, increase the nutrient level and animal performance and reduce the cost of production. The formula is based on NSP enzymes, multi-amylase and multi-protease.
All enzyme raw materials used in the KEMZYMETM MAP Dry formulation are selected from an extensive database with over 100 enzymes which have been screened by Kemin. The NSP enzymes (xylanase, cellulase, beta glucanase and pectinase) contained in KEMZYMETM MAP Dry are specially designed to release energy from multi-substrate complex diets for animals.
Dietary starch is a polymer made up of glucose, which is linked by two types of bonds – α 1,4 and α 1,6. Each bond is classified as “endo” and “exo” based on location in the molecule. To maximize starch digestion, both bonds have to be hydrolyzed from all sides. The multi-amylase system ( α amylase, gluco amylase and pullulanase) ensures the breakage of exo and endo bonds to achieve better starch digestibility.
Many commercial feed enzymes use a “neutral protease” enzyme for the improvement of protein utilization in animal diets. Kemin’s patented multi-protease system (acidic, neutral and alkaline proteases) demonstrate that the combined application of acidic, neutral and alkaline proteases release more amino acids and significantly improve the bioavailability of nitrogen in vivo.
In vivo ileal digestibility studies in broilers conducted at Massey University, New Zealand, showed that multi-proteases, a combination of proteases with different pH optima, have a significant effect on amino acid digestibility of corn-soybean meal diets in broilers over a single neutral protease enzyme. Multi-enzyme products containing a multi-protease system will therefore achieve higher economic benefit through the energy and amino acid sparing effects on the animal diets.
A growth trial was conducted at Bangkok Animal Research Center, Thailand. 240 birds were divided in to 3 groups with 8 replicates and 10 birds per replicate. Diets used for the growth trial were (1) Positive control diet (corn-soybean), (2) Negative control diet (energy reduced by 100 kcal/kg by replacing corn and soybean using DDGS, canola meal, cassava, rice bran and crude protein reduced by 0.5%) and (3) Negative control diet + KEMZYMETM MAP Dry (0.5 kg/t). Results are shown in Table 1.

A study was conducted at CNF Farm in Kabinburi, Thailand, at a closed monitor layer house with wire laying cages in air-step arrangements. The birds were kept 2 per cage with 6 replicate and 20 birds per replicate. Diets used for the trial were (1) Positive control diet (corn, soybean, meat cum bone meal), (2) Negative control diet (energy reduced by 60 kcal/kg by replacing corn and soybean using DDGS, cassava, rice bran and crude protein reduced by 0.5%) and (3) Negative control diet + KEMZYME™ MAP Dry (0.25 kg/t).
A swine trial was conducted at the Institute of Agricultural Studies, Vietnam to determine KEMZYME™ MAP Dry’s conclusive performance on digestibility. Pigs were housed individually in metabolism crates (0.8 x 1.5 m). Each metabolism crate had a collection tray for urine collection and a fine-mesh net just above the tray for fecal collection allowing for separate but total collection of feces and urine. Pigs were fed ad libitum and diets were fed in mash form. Results of the ileal amino acid digestibility trial are shown in figure 3.
The swine growth trial was conducted from 30 to 90 days period at Institute of Agricultural Studies (IAS) Vietnam. Diets used for the growth trial were (1) Positive control diet (corn, soybean, rice bran, fish meal), (2) Negative control diet (Less 60 kcal/kg ME and 0.5% Crude Protein), (3) Negative control diet + KEMZYMETM MAP Dry (0.5 kg/t) and (4) Negative control diet + Competitor enzyme product (0.5 kg/t). Results of the performance trial are shown in table 2.
|Positive Control Diet||Negative Control Diet||Control + KEMZYME™ MAP DRY||Control + Competitor Enzyme|
|Body Weight Gain (kg/pig)||25.95ₐ||25.12ₐ||27.66ₐ||25.90a|
|Feed Intake (g)||49.08ₐ||49.22ₐ||49.63ₐ||48.78|
