Summary

Wheat middlings (WM) can be incorporated into laying hen diets at levels of 25-45% without negatively impacting egg production. However, higher WM inclusion may lead to poorer feed utilization.

Area of Science:

  • Animal Science
  • Poultry Nutrition
  • Feed Science

Background:

  • Wheat middlings (WM) are a potential ingredient for poultry feed.
  • Evaluating WM for laying hens is crucial for sustainable feed formulation.

Purpose of the Study:

  • To assess the feasibility of using wheat middlings (WM) in laying hen diets.
  • To determine the impact of WM on egg production and hen performance across different commercial strains.

Main Methods:

  • Three long-term experiments involving floor pens and cages.
  • Diets with varying WM inclusion (25-89%) and salt levels were fed to commercial laying hens.
  • Performance metrics including egg production, feed intake, egg weight, and livability were recorded.

Main Results:

Related Experiment Videos

  • Diets with 45% WM supported higher hen-day egg production than diets with 89% WM.
  • A 25% WM diet improved egg weight, feed intake, and feed utilization compared to a corn-soybean meal diet.
  • No significant effects of WM or salt on yolk color, Haugh units, livability, or reproductive parameters were observed.

Conclusions:

  • Commercial laying hens can tolerate diets containing 25-45% WM with normal egg production.
  • Higher WM inclusion (89%) negatively impacted egg production and increased feed/water intake.
  • Feed utilization may be reduced with higher WM inclusion, necessitating careful formulation.
