Laying Performance of Japanese Quail Fed Ration with Different Levels of Golden Apple Snail Meal (Pomacea canaliculata) as Substitute to Fishmeal

— Five different levels of Golden Apple Snail Meal (GASM) as fishmeal substitute in laying Japanese quail ration were tested on the basis of total number of eggs produced, average weight of egg produced, feed conversion ratio and cost and return analysis including ROI, in a Randomized Complete Block Design experiment with 5 treatments which were replicated 4 times and 10 birds per replication. Results revealed that Treatment 1 (100% Fishmeal + 0% GASM) produced the highest average number of eggs in 15 months period with 436, but is not significantly different from Treatment 2 (75% Fish meal + 25 GASM) and Treatment 3 (50% Fishmeal + 50% GASM) with 432.50 and 427.50 respectively. However, Treatment 4 (25% Fishmeal + 75% GASM) and Treatment 5 (100 % GASM) had significantly lesser average number of eggs than Treatments 1, 2 and 3, and Treatment 4 is significantly higher than Treatment 5, with 252.75 and 192.50 respectively. No significant difference was observed on the average weight of quail eggs produced in five treatments while birds in treatments 1, 2, and 3 had significantly better feed conversion ratio than treatments 4 and 5. GASM can be a partial substitute to fishmeal in laying quail ration up to 50%. Beyond this the laying performance of Japanese quail declines.
