Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Mechanistic Models: Compartment Models in Individual and Population Analysis

109
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Area of Science:

  • Animal Science
  • Agricultural Engineering
  • Data Science

Background:

  • Broiler production relies on environmental and flock variables, yet housing control often prioritizes temperature.
  • Current methods lack comprehensive assessment of overall rearing condition suitability.

Purpose of the Study:

  • To develop a predictive model for broiler rearing condition suitability.
  • To identify key environmental and flock variables influencing optimal broiler housing.

Main Methods:

  • Data mining approach using flock-based and environmental variables from commercial broiler houses.
  • Exploratory data analysis, target variable labeling (Excellent, Good, Moderate, Inappropriate), and decision-tree model development.
  • Evaluation of random-tree and decision-tree models for predictive accuracy.

Main Results:

  • The decision-tree model demonstrated high accuracy in predicting rearing conditions.
  • Broiler age, relative humidity, and ammonia concentration were identified as critical factors.
  • The model generates 'if-then' rules to guide environmental control decisions.

Conclusions:

  • A data-mining approach can effectively predict broiler rearing suitability.
  • Key variables like age, humidity, and ammonia are crucial for optimal broiler housing.
  • The developed model supports informed decision-making for broiler farmers to improve production.
