W e need to look beyond the pens,points of entering to farms,the environment ,all means of conveying materials into the pen/farms most be distinfected before taking into the farm.

Glutamine and Arginine: These amino acids support the immune system, reducing the impact of diseases and stress on feed intake.however ,all amino acid required at this stage are critical for use and absorption.

thanks for the knowledge shared.

It really work and there improvement on the birds.

it prevent anti-nutritional factors on birds

improve feed conversion and absorption rate.

it prevent the feed shelf life.

I think it’s good to use in drinking water.in hot weather feed consumption already decreased.

The short answer is a definitive yes, enzymes absolutely work in poultry. Their efficacy is no longer a matter of debate but is a well-established scientific fact backed by decades of research and practical application in the field.

Let’s delve into the details.

Do Enzymes Really Work? The Evidence and Mechanism

The question is not if they work, but how and under what conditions. Their effectiveness hinges on understanding their mechanism:

1. Countering Anti-Nutritional Factors (ANFs): The primary target in plant-based ingredients (like soybean meal, corn, wheat, and barley) is the cell wall, composed of Non-Starch Polysaccharides (NSPs).

· In Soluble NSPs: In grains like wheat, barley, and rye, soluble NSPs (e.g., arabinoxylans, beta-glucans) create a viscous gel in the gut. This gel:

· Traps nutrients, preventing their access to digestive enzymes.

· Impairs nutrient absorption.

· Leads to wet, sticky litter (a clear sign of poor digestion).

· Enzyme Action: NSP-degrading enzymes (xylanase, beta-glucanase) break down these soluble fibers, reducing viscosity, releasing trapped nutrients, and improving gut health and litter quality.

2. Unlocking Phosphorus and Minerals: A significant portion of phosphorus in plant ingredients (60-80%) is stored as phytate (phytic acid).

· Phytate is poorly digested by poultry as they lack the endogenous enzyme phytase.

· Phytate also chelates (binds) other critical minerals like Calcium, Zinc, Manganese, and Copper, making them unavailable.

· Enzyme Action: Phytase breaks down phytate, liberating the bound phosphorus and minerals. This is the most successful and widely adopted enzyme in the industry. Its benefits are so profound that we now use “super-dosing” levels to unlock additional energy and amino acids from the diet.

3. Improving Standardized Ileal Digestibility (SID): By breaking down the fibrous cell walls, enzymes expose the protein and starch inside to the bird’s own proteases and amylases. This leads to a measurable increase in the digestibility of amino acids and energy, allowing for more precise and cost-effective diet formulation.

In my experience, the proof is seen in:

· Improved FCR: Better nutrient utilization directly translates to less feed per kg of body weight.

· Reduced Nutrient Excretion: This is a major environmental benefit, significantly lowering phosphorus and nitrogen in manure.

· Better Litter Quality: Reduced viscosity leads to drier litter, which improves paw quality and reduces ammonia levels.

· Cost-Effective Formulation: The “matrix values” for energy, amino acids, and phosphorus provided by enzymes allow for the use of lower-cost, alternative ingredients without sacrificing performance.

Beneficial Enzyme Cocktails: A Strategic Approach

No single enzyme works for all situations. The ideal cocktail is dictated by the dietary composition.

Here is a breakdown of the most beneficial enzymes and how they are combined:

1. The Base Cocktail for Corn-Soybean Meal Diets

This is the most common diet globally.

· Primary Enzyme: Phytase

· Role: Liberates phosphorus, calcium, and other minerals. With super-dosing (500 FTU/kg and above), it also improves energy and amino acid digestibility by breaking down the protein-phytate complex.

· Experience: This is non-negotiable. The return on investment is exceptional.

· Secondary Enzyme: Protease

· Role: Breaks down specific protein bonds that are resistant to the bird’s endogenous proteases (e.g., in soybean meal and other protein sources). It helps overcome the variability in protein digestibility of ingredients.

· Benefit: Improves amino acid digestibility, reduces undigested protein in the lower gut (which can feed pathogenic bacteria like Clostridium), and supports gut health.

· My Thought: Protease is increasingly moving from a “nice-to-have” to a “must-have” in corn-soy diets, especially in markets with variable ingredient quality or when using alternative protein sources.

· Tertiary Enzyme: Xylanase (or a multi-Carbohydrase)

· Role: While corn is low in soluble NSPs, it still contains a significant amount of insoluble arabinoxylans. Xylanase helps break down these fibers, releasing encapsulated energy and starch.

· Benefit: Provides a consistent energy boost, improves starch digestibility in the ileum, and supports gut integrity.

Recommended Cocktail for Corn-Soy: Phytase + Protease + Xylanase

2. The Comprehensive Cocktail for Wheat/Barley/Rye-Based Diets

These grains are high in soluble NSPs, making NSP-enzymes absolutely critical.

· Primary Enzyme: NSPase Cocktail (Xylanase + Beta-Glucanase)

· Xylanase: Targets arabinoxylans in wheat and rye.

· Beta-Glucanase: Targets beta-glucans in barley and oats.

· Role: Drastically reduce gut viscosity, unlock trapped nutrients, and prevent wet litter.

· Secondary Enzyme: Phytase

· Just as important as in corn-based diets to unlock phosphorus and minerals.

· Tertiary Enzyme: Protease & Amylase

· Protease: As above.

· Amylase: Can help further improve starch digestion, especially in young chicks with underdeveloped enzyme systems or during heat stress when enzyme secretion may be reduced.

Recommended Cocktail for Wheat/Barley: Xylanase + Beta-Glucanase + Phytase + Protease

3. The “Next Generation” & Gut Health Cocktail

This approach focuses on maximizing gut health and prebiotic effects.

· Enzymes: Multi-Carbohydrase Complexes

· These are advanced cocktails that include xylanase, beta-glucanase, cellulase, pectinase, mannanase, etc.

· Role: Their goal is not just to reduce viscosity but to thoroughly break down a wide range of fiber structures into smaller fragments called Prebiotic Oligosaccharides.

· Benefit: These oligosaccharides selectively feed beneficial gut bacteria (like Lactobacillus and Bifidobacteria), acting as a prebiotic. This leads to a more robust and stable gut microbiome, which is the cornerstone of immunity and overall health.

· My Experience: The shift from single-enzyme to multi-enzyme complexes is one of the most significant advancements. The benefits in gut health and flock uniformity, particularly in antibiotic-reduction programs, are very clear.

Key Considerations for Effective Use

Yes, enzymes work in poultry to improve nutrient digestion and overall performance. A beneficial enzyme cocktail typically includes phytase, proteases, amylase, and xylanase to help break down non-starch polysaccharides, proteins, and starches, respectively. This combination improves digestibility, nutrient absorption, and can lead to a more efficient feed conversion ratio, better bone health, and reduced environmental impact from phosphorus excretion.
