The nutritional balance of your feed may be right, but does it matter if the animals can’t benefit from it?
To maximize performance and the margin of return with monogastrics, it’s vital the animals are able to break down the food they’re consuming and get the nutrients they need. The industry standard of adding single enzyme products to feed yields mixed results.
A well-designed multi-enzyme blend, such as DigeGrain Delta, is cost effective, addresses all major feed challenges for monogastrics and is more efficient than a single enzyme blend. Plus, studies show it gets results – increased metabolic energy and reduced costs!
The Top 5 Feed Challenges for Monogastrics
Monogastrics face numerous feed challenges, including:
- Inability to break down fiber and NSPs in feed
- Inefficient utilization of energy in food
- Difficulty digesting protein (anti-nutritive factors)
- Reduced bioavailability and absorption of nutrients
- Increased inflammation, tissue damage and gut necrosis
Individual enzymes cannot resolve all these issues, but an efficient multi-enzyme blend, like DigeGrain Delta, addresses these challenges.
NSP and Fiber Degradation & Metabolizable Energy
NSP and fiber degradation is an inherent barrier to the digestion of various feed ingredients used for monogastrics. DDGS offers more energy than a single ingredient, such as corn. However, this only benefits the animal if they can fully digest the feed to access this energy.
Corn DDGS has 1000 kcal more energy than corn itself but the metabolizable energy (ME) of corn and DDGS is similar. However, as DDGS has significantly more NSPs than corn, the 1000 kcal advantage (in terms of gross energy) is irrelevant. In fact, in a corn-soy diet, 440-500 kcal of energy is unutilized while in a DDGS-based diet, the number climbs to 1350 kcal. Most of the energy in corn comes from starch, which is easily digested, whereas in DDGS the energy comes from NSPs.
Pigs and poultry cannot utilize NSPs as efficiently as they utilize starch. Because the NSPs are so difficult for monogastrics to break down, a diet of DDGS leads to inefficient utilization of metabolizable energy. To improve energy utilization from feed ingredients, a high NSP diet has much greater potential than a low NSP diet if the animal can efficiently break down NSPs.
Using the right combination of exogenous enzymes is the key to improving metabolizable energy utilization and successful NSP digestion. Standalone enzymes can only go so far alone, but in a blend, they pack a powerful punch with multi-enzyme activity.
For successful NSP hydrolysis or fermentation, enzyme blends like DigeGrain Delta, which includes protease, amylase, mannanase, xylanase and phytase, make a much greater impact than standalone enzymes.
Protein Digestion & Anti-Nutritional Factors
Monogastrics produce digestive enzymes, but their endogenous production is not high enough to meet the demands of a high protein diet.
Protein is another anti-nutritional factor source not digested by endogenous enzymes in monogastric animals. Like metabolizable energy, 12-15% of dietary protein remains undigested in monogastrics and causes environmental pollution, in the form of gas.
Other major anti-nutrients found in plant-based foods are phytates, tannins, alkaloids, lectins, oxalates, etc. Phytate is of particular concern, as it reduces the bioavailability of micronutrients, such as iron and zinc.
DigeGrain Delta includes the right proteases, along with other NSP-degrading enzymes and phytases, which are needed to overcome anti-nutritional challenges from protein, phytates and other anti-nutrients in complex feed ingredients.
Reduced Bioavailability and Absorption of Nutrients
Viscosity is caused by the water absorbing capacity of undigested soluble NSPs. NSPs absorb water and swell, increasing the viscosity of the digesta. The increase in the viscosity of food materials in the gut lumen increases the transit time of digesta through the gastrointestinal tract. The viscosity of the digesta and the slow passage rate of food negatively impacts contact between the villi and nutrients, and reduces nutrient absorption and diffusion in the gut.
When passed to the large intestine, these undigested and unabsorbed nutrients establish an environment for pathogenic microbes to proliferate, creating an imbalance in the gut microbial ecology. Proliferation of such pathogens have a detrimental effect on gut morphology by inducing inflammation and oxidation, which leads to tissue damage and gut necrosis.
As the digesta transit time is increased, the poultry feel consistently full which reduces feed intake, thus impacting performance and margin of return.
A well-formulated, multi-enzyme blend supports the gut microbiome.
The Solution – DigeGrain Delta
To maintain good health and gain weight, monogastrics must be able to break down animal feed and access the available nutrients it contains. DigeGrain Delta is a single, effective solution to all the top digestive challenges for monogastrics.
A unique multi-enzyme preparation with broad-spectrum xylanases, mannanases, amylases, proteases and phytase, DigeGrain Delta supports digestion of soluble and insoluble NSPs, proteins and phytates. It also degrades a variety of anti-nutritional factors and trypsin inhibitors, and releases bound phosphorus.
DigeGrain Delta is stable in a broad pH range, pellet and heat-stable, shelf-stable and resistant to gastric juices. The combination of enzymes in DigeGrain Delta is critical for complete degradation of complex feed to improve nutrient utilization and performance.
Aside from degrading the nutrient encapsulation effect of NSPs, DigeGrain Delta is proven to lead to fewer necrotic lesions in the gut. It also helps to maintain gut integrity and gut microbial ecology by supplementing oligosaccharide formation, namely xylo-oligosacchariedes (XOS) and manno-oligosaccharides (MOS).
Both XOS and MOS are known to have a potent butyrogenic effect and provide nutrients to encourage the growth of beneficial microbes in the gut. The butyrate supplies energy to the epithelial cells, helping to maintain gut integrity.
The addition of DigeGrain Delta to animal feed helps to improve nutrient digestibility, maintain stable gut microflora and protect against pathogenic organisms.
DigeGrain Delta can extract 130 kcal energy, or 30% of metabolizable energy, from a corn-soy diet in poultry (out of the 440 kcal that is not utilized) and more than 150 kcal in high NSP diets. It is proven to save up to $0.26 USD per bird or $1 USD per pig.
