Dietary supplementation with multienzyme preparations improves nutrient utilization and growth performance in weaned...

Area of Science:

• Animal Nutrition
• Swine Physiology
• Digestive Enzyme Technology

Background:

• Young pigs have specific nutritional requirements that can be challenging to meet with conventional feed ingredients.
• Phytate and non-starch polysaccharides (NSP) in plant-based diets reduce nutrient digestibility and availability.
• Multienzyme preparations offer a potential strategy to enhance nutrient utilization in swine diets.

Purpose of the Study:

• To evaluate the efficacy of three distinct multienzyme preparations (A, B, and C) in young pigs.
• To assess the impact of enzyme supplementation on nutrient digestibility, growth performance, and phosphorus metabolism.
• To determine the optimal enzyme preparation for improving diet formulation cost-effectiveness and environmental impact.

Main Methods:

• Two experiments were conducted with young pigs (25 days of age).
• Experiment 1 involved a 28-day digestibility and performance trial with four diets (control and three enzyme-supplemented).
• Experiment 2 was a 38-day growth performance study comparing control and the most effective enzyme (Enzyme C) diets.

Main Results:

• Enzyme supplementation significantly improved ileal and total-tract digestibility of dry matter, energy, protein, starch, NSP, and phytate.
• Pigs fed enzyme-supplemented diets exhibited higher average daily gain (ADG) and gain-to-feed (G:F) ratios.
• Fecal phosphorus excretion was reduced in pigs fed enzyme-supplemented diets, with Enzyme C showing the greatest improvements.

Conclusions:

• Multienzyme preparations enhance nutrient digestibility and growth performance in young pigs.
• Enzyme supplementation can lead to reduced phosphorus excretion, contributing to environmentally friendly swine production.
• The use of multienzymes allows for more cost-effective and sustainable diet formulations for young pigs.
