| The aim of the present study was to evaluate the potential utilization of DDGS on diet of Nile Tilapia by chemical and digestibility analyses. Firstly, the chemical composition of the ingredient was evaluated and then were made two diets: a reference one and a test diet made of 80% with the reference diet and 20% with DDGS, for the digestibility study. For the faeces collection was used the indirect method, using chromium oxide as an inert marker. After the collection, the faeces were destined to chemical composion analysis and so the experimental diets. With the results, the Nile Tilapia coefficient of digestibility of the DDGS nutrients was calculated. Proteins and total lipids mainly compose the DDGS, which gives its high concentration of crude energy.... |

| 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... |
