Abstract
O presente trabalho foi desenvolvido para avaliar a influência de diferentes fontes de lipídios sobre o desempenho de larvas de jundiá (Rhamdia quelen). Foi realizado no Setor de Piscicultura do Departamento de Zootecnia da Universidade Federal de Santa Maria, utilizando-se um sistema de criação de larvas com recirculação d'água, termorregulada. O experimento teve duração de 21 dias, testando-se 7 tratamentos com três repetições. Testaram-se diferentes fontes de lipídios: óleo de canola, óleo de soja, óleo de fígado de bacalhau, óleo de girassol e óleo de milho, incorporados na proporção de 5% de uma dieta base (fígado e levedura). O tratamento com óleo de canola resultou em 94% de sobrevivência e larvas com 19,97mm de comprimento total e 54,3mg de peso médio. De acordo com os resultados obtidos no experimento, conclui-se que os óleos de canola e fígado de bacalhau são mais eficientes como suplemento lipídico na nutrição de larvas de jundiá (Rhamdia quelen).
The present study was developed in order to evaluate the influence of different sources of fat on the Rhamdia quelen larvae performance. It was carried out at the Animal Husbandry Department - Fish culture Section of the Federal University of Santa Maria, using a system of larvae culture with thermoregulation and recirculation of water. There were seven (7) treatments, with three replicates each one and the different sources of fat tested during 21 days were: canola oil, soybean oil, cod liver oil, sunflower oil or corn oil incorporated in the rate of 5% of a basal diet (liver and yeast). The treatment with canola oil resulted in a 94% survival rate, and larvae with 19.97mm of total length and 54,3mg of individual body weight. According to the results obtained in the experiment, it was concluded that canola and cod liver oil are more efficient as fat supplement in Rhamdia quelen larvae nutrition.
