Effects of maize source and complex enzymes on performance and nutrient utilization of broilers

Area of Science:

• Animal Nutrition
• Poultry Science
• Feed Additives

Background:

• Maize is a primary energy source in broiler diets.
• Enzymes can enhance nutrient digestibility and broiler performance.
• Variability in maize quality necessitates evaluating its impact on nutrition.

Purpose of the Study:

• To assess the effects of different maize sources on broiler performance and nutrient utilization.
• To investigate the efficacy of complex enzymes (amylase, xylanase, protease) in broiler diets.

Main Methods:

• A 4x3 factorial experiment utilized four maize sources (M1-M4) and three enzyme treatments (none, enzyme A, enzyme B).
• Nine hundred and sixty Arbor Acres broiler chicks were randomly assigned to 12 treatment groups.
• Key performance indicators and nutrient digestibility were measured.

Main Results:

• Maize source M1 improved body weight gain (BWG) and feed/gain ratio compared to M3 and M4.
• Enzyme A supplementation significantly increased BWG by 8.6%.
• Enzyme B reduced fresh feces output, and M2 showed higher crude protein digestibility than M3.

Conclusions:

• Maize source significantly influences broiler nutrient digestibility and overall performance.
• Complex enzymes containing amylase, xylanase, and protease are effective in enhancing broiler growth.
• Optimizing maize sourcing and enzyme supplementation can improve broiler production efficiency.
