- Tilapia by-product hydrolysate powder in diets for Nile tilapia larvae Cesar Sary Leandro Daniel De Paris Daniela Miotto Bernardi Vanessa Lewandowski Altevir Signor Wilson Rogério Boscolo Agrociencias Performance Digestibility Fish nutrition This study aimed to evaluate the digestibility of tilapia by-product protein hydrolysate powder (TBHP) from tilapia filleting by-product, and its inclusion in diets for Nile tilapia larvae. In order to determine the apparent digestibility coefficients, two diets were formulated, the reference diet and the test diet (20% of TBHP) and, to evaluate the inclusion, six diets were formulated, which were with 0.0, 2.0; 4.0; 6.0, and 8.0% of TBHP. The apparent digestibility coefficients of crude protein and gross energy were 89.5 and 98.3%, respectively. At levels above 4.0% of inclusion of TBHP, the weight, final length and weight gain were impaired, however, survival rate was higher (p < 0.05). The TBHP can be used in diets for tilapia due to the high digestibility coefficients for crude protein and gross energy. The inclusion of up to 4.0% of TBHP does not affect the reproductive performance and survival rate of Nile tilapia larvae. 2017 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303149707001 https://www.redalyc.org/journal/3031/303149707001/ https://www.redalyc.org/journal/3031/303149707001/html/ https://www.redalyc.org/journal/3031/303149707001/303149707001.epub https://www.redalyc.org/journal/3031/303149707001/movil en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
