| O presente trabalho teve como objetivo avaliar diferentes metodologias de coleta de fezes para determinação da digestibilidade protéica de alimentos para a rã-touro (Rana catesbeiana). As metodologias estudadas foram o método de coleta total das fezes; o método de coleta parcial das fezes usando indicador; o método de dissecação intestinal e o método por decantação de fezes com indicador, utilizando aquários para ensaios de nutrição com peixes. Os resultados dos CDA PB da ração obtidos para avaliação dos métodos de coleta foram: 62,1%, 65,0%, 61,3% e 70,3%, respectivamente. Todos os métodos de coleta de fezes são adequados para a realização de ensaios de digestibilidade com rãs. |

| O objetivo deste trabalho foi avaliar o efeito da suplementação da dieta com os probióticos Lactobacillus plantarum e Saccharomyces cerevisiae, no desempenho zootécnico, digestibilidade e na resistência à infecção por patógeno, em alevinos de tilápia-do-nilo. Foram realizados três ensaios. No primeiro, durante 55 dias, seis grupos de 30 alevinos (2,4±0,5 g) receberam suplementação com probióticos, e outros três grupos não receberam suplementação. No final desse período, no segundo ensaio, os peixes foram desafiados com Aeromonas hydrophila, e a sobrevivência foi avaliada por 96 horas. No terceiro ensaio, com oito peixes por tanque (230,0±10,0 g), avaliou-se a digestibilidade da dieta após a suplementação com os probióticos. A suplementação probiótica... |

| The objective of this work was to isolate strains of lactic acid bacteria with probiotic potential from the digestive tract of marine shrimp (Litopenaeus vannamei), and to carry out in vitro selection based on multiple characters. The ideotype (ideal proposed strain) was defined by the highest averages for the traits maximum growth velocity, final count of viable cells, and inhibition halo against nine freshwater and marine pathogens, and by the lowest averages for the traits duplication time and resistance of strains to NaCl (1.5 and 3%), pH (6, 8, and 9), and biliary salts (5%). Mahalanobis distance (D²) was estimated among the evaluated strains, and the best ones were those with the shortest distances to the ideotype. Ten bacterial strains were isolated... |

| O objetivo deste trabalho foi isolar o agente causador da doença-da-perna-vermelha em girinos de Rana catesbeiana em fase de transformação. Coletaram-se 20 girinos, na fase G4, apresentando prostração, anorexia, pele ressecada, pernas posteriores hemorrágicas e natação errática. Amostras do coração, fígado e partes da perna foram inoculadas em meio de cultura ágar triptona de soja e ágar sangue, a 25°C, por 48 horas. Aeromonas hydrophila foi a principal causa do surto de mortalidade. A fim de avaliar o efeito dessa bactéria nos girinos, realizou-se inoculação por via oral e intraperitoneal de 10(6) unidades formadoras de colônia por mililitro, e verificou-se o aparecimento de petéquias hemorrágicas na boca e nos órgãos internos. |

| Este estudo avaliou o hemograma e a resposta inflamatória aguda em tilápia do Nilo alimentada com 500mg de vitamina C e 500mg de vitamina E/kg de ração. Após 30 dias de alimentação com a dieta suplementada com as vitaminas, 500µg de carragenina, 3mg de lipopolissacarídeo (LPS)/kg de peixe e 0,5ml de solução salina estéril (controle) foram injetados na bexiga natatória dos animais. Seis horas após, os peixes foram anestesiados para coleta de amostras sangüíneas e análise da resposta inflamatória. Peixes injetados com carragenina e LPS apresentaram as maiores contagens totais de leucócitos no sangue, sendo que a suplementação vitamínica na ração provocou redução no número total de trombócitos nos injetados com carragenina. A taxa de glicose, o número de... |

| ABSTRACTThe objective of this work was to evaluate the performance of Litopenaeus vannameifed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC), and daily water exchange (30%). Each tank was stocked with 37.5 shrimp/m3 (3.03±0.14 g). Feed was supplied four times a day, at 6% of the initial biomass, adjusted daily. After 42 days, the weight gain of shrimp fed diets with 0 and 25% protein replacement was higher than that observed in shrimp fed 100% replacement, and there were no differences among those fed the other diets. Feed efficiency and... |

| ABSTRACT This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets consisted of replacing 209 g kg-1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve experimental units stocked with 250 shrimp m-3 under constant aeration (O2>5mg L-1) and temperature (29±0.5 °C). No significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33% substitution exhibited the highest... |

| The objective of this work was to assess the time-related action of probiotic Lactobacillus plantarum in the bacterial microbiota of the digestive tract of Litopenaeus vannamei, and the relation of total haemocyte count and serum phenol oxidase activity of shrimp challenged with Vibrio harveyi. Shrimps were fed with a probiotic-supplemented diet, for eight days, then shifted to a commercial diet. Shrimps fed only with the commercial diet served as control. Evaluations were made on the 8th day of experiment and repeated two, four, six and eight days later. Total lactic bacteria in the digestive tract was higher until the 4th day of evaluation in the probiotic-supplemented group. Vibrio spp. counts were higher in the control at days zero and two. Until the... |

| ABSTRACT The objective of this study was to evaluate the use of a diet supplemented with Lactobacillus plantarum on performance, immunological parameters, and bacterial microbiota of the digestive tract of white leg shrimp (Litopenaeus vannamei). We used six earthen ponds (1.2 ha) stocked with 14 shrimp m−2 (3 g mean weight). Three ponds received a diet supplemented with L. plantarum and three were maintained as control. The survival and feed efficiency of shrimp fed the supplemented diet were greater than that observed in shrimp fed the control diet, with survival values of 83.02±6.12% and 74.65±9.07% and feed efficiencies of 117.97±4.45% and 104.46±7.30%, respectively. However, we observed no differences in weight gain. The intestines of shrimp fed... |
