Farinha de larva de tenébrio molitor na alimentação de Tilápiado-Nilo

Abstract

This research was conducted at the Institute of Agricultural Sciences of UFMG, in the municipality of Montes Claros, MG, and had the objective of evaluating the inclusion of Tenébrio Molitor larvae meal in Nile tilapia feeding. A total of 200 juveniles of tilapia were distributed in 20 polyethylene tanks with a capacity of 130 liters, in a completely randomized design, consisting of five treatments and four replicates. The treatments used were composed of isoproteic and isoenergetic rations, without the presence of insect meal and the others with 6.5; 13; 19.5 and 26% of the digestible protein derived from meal of Tenébrio Molitor larvae. The parameters of productive performance, glucose, vicerosomatic and hepatosomatic indexes were evaluated. It can be observed that among the evaluated parameters, the final biomass, the biomass gain, the final weight, the weight gain and the apparent feed intake were influenced by the inclusion of flour of tenébrio in the rations, being the treatment with the inclusion of 26% insect meal which provided the best results.
