Growth, laying performance and egg quality traits of Japanese quails (Coturnix coturnix japonica) fed with papaya (Carica papaya) leaf meal / Princes Diane B. Alipio City of Batac : MMSU, 2024. xii, 61 leaves : 29 cm. Thesis (BS in Agriculture major in Animal Science) -- Mariano Marcos State University-College of Agriculture, Food and Sustainable Development, Batac City Bibliography : leaves 37-41 This study was conducted at Barangay Elizabeth, Marcos, Ilocos Norte from 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. lcc THEDIS 24312 24312 0 0 lcc 0 0 MMSU_MAIN MMSU_MAIN THESES 2024-12-10 7486 0 UTHESIS-7486 2024-12-10 2024-12-10 THEDIS Room Use Only
