SOYBEAN MEAL AS A PARTIAL SUBSTITUTE FOR MOLASSE YEAST IN THE FEEDING OF PIAVUÇU Leporinus macrocephalus LARVAE
Abstract
The experiment was conducted to evaluate natural and artificial feeding for piavuçu larvae. Different formulations with raw chicken Tiver and molasse yeast were tested, but soybean meal was used as a partial substitute for molasse yeast at the proportions of 0 % for Treatment 1 (TI), 25 % for T2, and 50% for T3. Also, a fourth treatment (T4) was tested, using T l plus natural food (Artemia fr-anciscana nauplii). The four treatments and four repetitions were arranged in a completely randomized design. According to the obtained data, we concluded that artificial feeding introduced better results, and the use of soybean meal up to the levei of 50 % did jeopardize the larvae growth.
