| description | The bioimpedance is a method used to estimate humans and animals body composition, characterized by determining the value of the phase angle. This study aimed to estimate the fish condition through electrical bioimpedance technique and evaluate the performance of Nile tilapia grown in sewage water treated with the addition of probiotic (Bacillus licheniformis, Bacillus cereus and Bacillus subitillis and yeast - Saccharomyces cerevisiae and boulardi) in diets. For the experiment, 360 fingerlings were used with initial average weight of 2.91 ± 0.37 g and initial average length of 3.30 ± 0.27 cm, distributed in a completely randomized design with three treatments and six repetitions of 20 fish each. Treatments consisted of: PRO1 - fish grown in clean water; RO2 - fish grown in wastewater; PRO3 - fish grown in wastewater + probiotic added to the feed. All animals were fedto apparent satiety. Tilapia that were submitted to the health challenge (wastewater) presented phase angle less than 15°. Fulton´s K value was higher for the group treated with sewage water. The wastewater does not present conditions for a good crop and a good development of the fish, regardless the probiotic supplementation and the measurement method of health status used. The probiotic strains did not led to an improvement of fish performance and survival. |

A bioimpedância é um método utilizado para estimar de composição corporal em humanos e animais, caracterizado pela determinação do valor do ângulo de fase. Objetivou-se estimar a condição dos peixes por meio da técnica de bioimpedância elétrica e avaliar o desempenho de tilápias-do-nilo cultivadas em água de esgoto doméstico tratado com a adição de probiótico (Bacillus licheniformis, Bacillus cereus e Bacillus subitillis e leveduras –Saccharomyces cerevisiae e Saccharomyces boulardi) em rações. Foram utilizados 360 alevinos, com peso médio inicial de 2,91 ± 0,37 g e comprimento médio inicial 3,30 ± 0,27 cm, distribuídos em delineamento inteiramente casualizado, com três tratamentos, seis repetições de 20 peixes. Os tratamentos consistiram de: PRO1 - peixes cultivados em água tratada; RO2 - peixes cultivados em água residuária,; PRO3 - peixes cultivados em água residuária + probiótico adicionado na ração. Todos alimentados até a aparente saciedade. As tilápias que estavam submetidas ao desafio sanitário (água residuária) apresentaram ângulo de fase menor que 15°. O K de Fulton foi superior no grupo de peixes de água de esgoto doméstico tratado. A água residuária não apresenta condições para um bom cultivo e um bom desenvolvimento dos peixes, independentemente do uso de probiótico e do método de aferição do estado de saúde utilizado. As cepas probióticas não promoveram melhorias no desempenho desses peixes e nem na sobrevivência. 2016-11-04 2022-03-21T20:07:36Z 2022-03-21T20:07:36Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/924 10.14295/cs.v7i2.924 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77743 por https://comunicatascientiae.com.br/comunicata/article/view/924/406 https://comunicatascientiae.com.br/comunicata/article/view/924/651 https://comunicatascientiae.com.br/comunicata/article/view/924/662 application/pdf application/zip application/vnd.openxmlformats-officedocument.wordprocessingml.document Federal University of Piauí Comunicata Scientiae; Vol. 7 No. 2 (2016); 262-271 Comunicata Scientiae; v. 7 n. 2 (2016); 262-271 2177-5133 2176-9079 |
