Statistical Analysis on the Effect of Feeds on Chicken Weight and Egg Production

Abstract

This study evaluated the effects of three commercial poultry feed brands—
Metrovet, Topfeed, and Chikun—on the body weight and egg weight of laying 
chickens. A total of nine (9) layer chickens were used for the experiment, which 
was conducted over a five-month period. The birds were randomly assigned to 
three treatment groups, with each group receiving one of the three feed types 
throughout the study duration. Data on chicken body weight and egg weight were 
collected and analyzed to determine the influence of the different feeds on 
growth and egg production performance. A Completely Randomized Design (CRD) 
was adopted, and Analysis of Variance (ANOVA) was employed to assess 
differences among the feed treatments. The ANOVA results revealed no 
statistically significant differences (p > 0.05) in the mean body weight of 
chickens or the mean egg weight among the three feed types. To further 
investigate pairwise differences, Independent Sample t-tests were conducted. 
The results showed significant differences in mean chicken body weight between 
Metrovet and Topfeed, as well as between Metrovet and Chikun, whereas no 
significant difference was observed between Topfeed and Chikun. Similarly, 
pairwise comparisons of mean egg weight indicated statistically significant 
differences among all feed combinations. Despite the significant differences 
detected in some pairwise comparisons, the overall ANOVA results suggest that 
the three feed types did not exert a statistically significant effect on the 
average body weight and egg weight of the laying chickens. It is therefore 
concluded that Metrovet, Topfeed, and Chikun feeds produce comparable 
performance in terms of chicken growth and egg weight under the conditions of 
this study.
