Resumo
Este trabalho avaliou o efeito de dietas contendo probiótico e espirulina sobre a formação de macrófagos, variáveis hematológicas e bioquímicas em tambaqui Colossoma macropomum jovens mantidos em duas densidades de estocagem. Previamente foi conduzido por três meses com três dietas alimentares - grupo controle, probiótico e espirulina; utilizando três caixas de água com capacidade de 500 L em sistema aberto de produção com renovação de água e filtragem biológica. Posteriormente, o experimento teve a duração de 12 dias, utilizando 36 caixas plásticas com capacidade de 50 L, com aeração e renovação de água constantes. O delineamento experimental foi inteiramente casualizado em um esquema fatorial 3 x 2 x 2 (dietas x densidade de estocagem x lamínulas), totalizando em 12 tratamentos, onde cada tratamento apresentava um grupo com peixes implantados lamínulas (I) e outro grupo com peixes sem implantes de lamínulas (S), apresentando três repetições cada, sendo: T1 – ração controle com densidade 5 kg/m3 com (I) e (S); T2 – 1g probiótico/kg ração com densidade 5 kg/m3 com (I) e (S); T3 – 5g espirulina/kg ração com densidade 5 kg/m3 com (I) e (S); T4 – ração controle com densidade 20 kg/m3 com (I) e (S); T5 – 1g probiótico/kg ração com densidade 20 kg/m3 com (I) e (S); T6 – 5g espirulina/kg ração com densidade 20 kg/m3 com (I) e (S). Foram coletados dois indivíduos por tratamento, nos intervalos de 0, 3, 7, 10 e 12 dias experimentais para avaliação das variáveis hematológicas, bioquímicas e contagem dos núcleos das células gigantes. Os resultados mostraram que a suplementação da dieta de tambaqui com probiótico ou espirulina não causaram alterações nos valores hematológicos, bioquímicos e na formação de célula gigante. Contudo, ocorreu maior...
The aim of this experiment was to evaluate the effect of diets contend probiotic and spirulina on small glass blades implanted, hematological and biochemistry parameters of tambaqui, Colossoma macropomum, juveniles, submitted the two different stockage density. The pay-experimental period was lead by three months with three alimentary diets – control group I, group contend probiotic in diet and group contend spirulina in diet; three boxes were used in a 500 L water capacity, in open system of production with water renewal and biological filtering. After, the experiment had the duration of twelve days; thirty six plastic boxes were used in a 50 L, with aeration and constant water renewal. The experimental design was a factorial design - 3 x 2 x 2 (diets x stockage density x small glass blades), totalizing in twelve treatments, presented a group with small glass blades implanted fish (I) and another group with fish without implantations of small glass blades (S), with three repetitions each, being: T1 - ration has controlled in density 5 kg/m3 with (I) and (S); T2 - ration contend 1g probiotic/kg in density 5 kg/m3 with (I) and (S); T3 - ration contend 5g spirulina/kg in density 5 kg/m3 with (I) and (S); T4 - ration has controlled in density 20 kg/m3 with (I) and (S); T5 - ration contend 1g probiotic/kg in density 20 kg/m3 with (I) and (S); T6 – ration contend 5g spirulina/kg in density 20 kg/m3 with (I) and (S). Were collected two fish for treatment, in the intervals of 0, 3, 7, 10 and 12 experimental days for evaluation of the hematological and biochemistry parameters, and counting of giant cells nucleus. The results had shown that the diet supplemented of with probiotic and spirulina had not caused alterations in the hematological and biochemistry parameters and in the formation of giant cell o tambaqui.
