Theory

  • Introduction to the EFG Broiler model

    To predict growth and feed intake requires a description of the breed of bird, the growth environment, the feeds which will be fed and the method of feeding.

  • Determining the genetic growth parameters

    The Gompertz growth curve parameters that must be defined are mature protein weight, rate of maturing, and time taken to reach 0.368 of mature size.

  • References

    References to articles and papers published by researchers such as Gous RM, Emmans GC, Fisher C, Gompertz B, Jennings RC, to name a few.

  • Theory of Growth

    It is possible to describe the potential growth rate and hence determine the nutrient requirements for potential growth of different genotypes.

  • Features to be aware of when using the model

    When using the Broiler Model, take careful note when running the growth simulation, choosing the genotype parameters and anticipated mortality of broilers.
