SUMMARY:

In view of the potential for productive growth of marine shrimp Litopenaeus vannamei and knowing that the use of exogenous protease enzyme in their rations can increase performance gains, it is of paramount importance to research on the use of enzymes in shrimp diets. There are still important gaps to be filled, such as the effect of diet supplementation on performance gain, the effect on the use of enzymes with the use of fishmeal and soybean meal as protein sources in the ration, in addition to the optimal doses. of supplementation considering the substrate present in the various nutritional formulations in which these animals are exposed. In this context, the objective was to quantify, through a systematic review with meta-analysis, the effect of the use of the exogenous protease enzyme in Litopenaeus vannamei shrimp diets. A search algorithm was built using formal descriptors from the DeCS and MeSH bases, together with keywords organized in conceptual blocks according to the PICO strategy. Several search strategies were developed and tested in PubMed, Scopus, Web of Science, Science Direct and Scielo databases and the one chosen based on the data obtained was “(pacific OR white OR shrimp OR "litopenaeus vannamei") AND (protease) AND (performance)”. After analysis, there is evidence that the use of exogenous protease enzyme in shrimp diets increases daily weight gain by 0.03g, improves feed conversion efficiency with a reduction of 0.17g/g, maintaining flock survival.
