THE EFFECTS OF DIFFERENT LEVELS SWEET POTATO LEAF MEAL ADDED TO THE COMMERCIAL RATION ON THE LAYING PERFORMANCE OF JAPANESE QUAIL （Coturnix coturnix)

The study on the laying performance of quails fed with different levels of sweet potato leaf meal added to commercial ration was conducted to determine the effects on feed consumption, hen-day egg production, feed conversion ratio (FCR), weight of eggs, percent mortality and economic returns. A Completely Randomized Design (CRD) was used in the study with three treatments replicated three times. Treatments used were 100% Commercial Layer Mash(T1),95%Commercial Layer Mash with (5%) Sweet Potato Leaf Meal and 90%Commercial Layer Mash with 10%Sweet Potato Leaf Meal. There were four birds in each replication. The study revealed a significant difference among the treatments on feed consumption. Meanwhile, the difference among treatments on feed conversion ratio, average egg weight and hen-day egg production was found not significant. Cost and return analysis showed that birds provided with 5% SPLM had the highest net income.
