Experimental design: The experiment was carried out in a Completely Randomized Design (CRD). Treatment
(Diet) was handled in three levels with three replicates.
The model used was :
Yij = µ + ti + €ij
Where:
Yij = Observed effect of the treatment on the performance of the birds
µ = Population mean
ti = Treatment effect
€ij = Error term associated with the observations
Assumptions: The error terms are randomly, independently and normally distributed with a mean, zero and a
common variance. The main effects is additive.
