Resumo: | This research was realized in two periods, one pre experimental in 112 days and other experimental in 43 days, aiming to evaluate the effects of vitamin C and lipid on differential leukocyte counts of fish submitted to temperature stress. Leukocyte cells were evaluated at the beginning and the end of the experiment. The experiment used a 2 x 3 factorial design with vitamin C (300.0; 600.0 and 1,200.0 mg/kg diet) and lipid levels (8.0 and 12.0%) with four replicates, plus absence of nutrient test and 6.0% lipids and 125.0 mg/kg vitamin C diet. Diets were formulated to contain 32.0% of DP. Fish were stocked into 24 40-L aquaria at a density of two fish/aquarium, with weight of 105.13 ± 19.71 g. Water temperature was kept at 18.0°C during 25 days and at 15.0°C during 11. Low temperature determine a decrease on leucocytes and lymphocytes and an increase on neutrophils and monocytes. There was a significant interaction between phase x vitamin C and phase x lipid. It was concluded that vitamin C and lipid supplementation improve immune response; low temperature determine a decrease in fish resistance; levels of vitamin C supplementation above the requirement and 8.0 and 12.0% of lipid on diet determine a better resistance.KEY WORDS: Ascorbic acid, low temperature, Oreochromis niloticus, resistance, white blood cell. |

Distribuíram-se os tratamentos num DIC em esquema fatorial 2 x 3, com níveis de lipídeo (8,0 e 12,0%) e níveis de vitamina C (300; 600 e 1.200 mg de vitamina C/kg dieta), com três repetições cada, além de outros dois tratamentos, ausente de suplementação dos nutrientes testes e acrescido de 6,0% de lipídeo e 125 mg de vitamina C/kg, constituindo oito dietas isoprotéicas (32,0% PD). Os peixes foram distribuídos em 24 aquários, dois peixes/aquário, com peso médio de 105,13 ± 19,71 g. A água dos aquários permaneceu a 18,0°C durante 25 dias e por 11 dias a 15,0°C. O estímulo pelo frio determinou leucopenia, linfopenia, neutrofilia e monocitose. Houve interação significativa para fase versus vitamina C e fase versus lipídeo. Conclui-se que a suplementação de vitamina C e lipídeo melhora o sistema imunológico; o estresse pelo frio diminui a resistência dos peixes; os níveis de suplementação de vitamina C na ração acima da exigência nutricional e níveis de 8,0% e 12,0% de lipídeo determinam melhor resistência.PALAVRAS-CHAVES: Ácido ascórbico, baixa temperatura, células brancas, Oreochromis niloticus, resistência.
