November 22 2023 to January 21, 2024 to determine the growth performance (initial 
weight, final weight, total gain in weight and average daily gain), health status 
(morbidity and mortality rates), laying performance (age at first egg. egg production, 
feed consumption, feed conversion ratio and feed cost per dozen egg), egg quality 
(egg weight, egg mass, and yolk color) of Japanese quails as well as profitability (net 
income and return on investment) of production.  
A total of 120 ready-to-lay quails were used in the study, and these were 
randomly and equally distributed into four dietary treatments and three replications 
following the Completely Randomized Design (CRD). The dietary treatments were as 
follows: (T0) 100% Pure Commercial Feeds (CF), (T1) 95% CF + 5 % Papaya Leaf 
Meal (PLM), (T2)-92.5% CF + 7.5% PLM, (T3) 90% CF + 10% PLM.  
Analysis was done using the Analysis of Variance (ANOVA) for CRD, and 
treatment means were compared using Least Significant Differences Test when 
ANOVA F-test showed significant result. The statistical tool used was STAR 2.0.1. 
The analysis revealed that quails fed with papaya leaf meal (PLM) showed no 
significant differences among treatments. Moreover, the inclusion of PLM did not 
significantly affect the laying performance and profitability. The groups did not differ in 
terms of initial weight, age at first egg, and fed conversion ratio or egg weight. 
Furthermore, there were no negative health effects or fatalities associated with the 
introduction of PLM. Further study is recommended to use PLM in growth and laying 
performance since it may have a negative impact resulting in decreased profitability in 
production.
