This study evaluated the inclusion of dehydrated blood plasma (PD) on Nile tilapia diet by a research divided in two stages: 1° Stage, after 60 days, was measured the productive performance and histological parameters of fish, whose received five diets: PD0 (control); PD 1,66; PD 3,32; PD 4,97; PD 6,63% of dehydrated blood plasma inclusion. 440 fish was randomized into 40 aquariums (250 L) with physic-biological filter and automatic system water control (26 ±1°C) on the 1°st. On the second stage, was evaluated hematological parameters of Nile tilapia juveniles, before and after the cold stress (16°C). During seven days, 60 fish were allocated in 30 aquariums (40 L), with individual aeration and filters, provided by a division in each, that assure individuals spaces. PD inclusion results presented greater weight gain, final weight and improves the intestinal integrity. Maintenance and/or stimulation of erythropoiesis was observed with the addition of PD, inferring better health and fish organic resistance exposed to stress by low temperature. Increased production of neutrophils and monocytes maintenance, demonstrated the stimulatory effect of PD on the innate immune system . The data was submitted to the analysis technique variance (P<0.05), complemented by the multiple comparison Tukey test. Regression analyzes were performed when the model was significant (R2>0.70). For outresults of the normal curve, was applied the nonparametric Kruskal-Wallis analysis (P<0,05), complemented by Mann-Whitney test comparisons. The inclusion of PD for Oreochromis niloticus on diet, improves growth performance, gut health, blood profile and organic resistance to stress by low temperature. Based on the results of growth performance and histology, is recommended the PD inclusion of 4.97 % on the diet, because it brings more benefits when compared to PD treatment without inclusion
