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