“…However, these data are in contrast with those obtained by (Mutlu et al, 2015) indicated that the differences of growth rates between control and copper sulfate-exposed groups were not significant (P>0.05) at the end of 35, 65 and 95 days. Moreover, vitamin C or β-glucan supplementation markedly improved growth performance and feed efficiency parameters which agree with (Baccarin and Pezzato, 2001). When fed lower content of protein (28.0% DP/3000 kcal DE/kg), but with addition of vitamin C (400 and 600 mg kg-1) and ß-glucan (0.10.8%), that species presented a satisfactory performance even with shorter periods of time (six weeks) than the ones observed in the present study (Falcon, 2007).…”

“…Baccarin & Pezzato (2001) and observed changes in the body constitution of fish supplemented with S. cerevisiae, which might cause a zoothecnical drawback due to the reduction of the proteic concentration and the storage of lipids. Those researchers reported that the biological value of protein that come from yeast presents imbalance of amino acids, resulting in the reduction of protein synthesis, turning it into energetic reserves.…”

Levels of yeast and its by-products on pacu juveniles feeding

2010

-This study was conducted to evaluate the inclusion of two levels (2.5 e 5.0%) of dried yeast (Saccharomyces cerevisiae) and its by-products, disrupted yeast cells and yeast cell wall in diets for juveniles of pacu (Piaractus mesopotamicus).Production performance, body and plasmatic composition indexes were evaluated. Seven isoproteic (26% digestible protein) and isoenergetic (3.100 kcal digestible energy) diets were formulated containing increased levels of each ingredient. The diets were supplied for 86 days, "ad libitum". Yeast and by-products increase feed efficiency and protein use, when compared to the control diet. Carcass composition and plasmatic (glucose, cortisol, uric acid, urea and plasmatic protein) levels are not affected by the test ingredient supplementation.Key Words: Piaractus mesopotamicus, pre-biotic, production performance, Saccharomyces cerevisiae, yeast by-products Níveis de levedura e derivados na dieta de juvenis de pacuRESUMO -Este estudo foi realizado com o objetivo de avaliar os efeitos da suplementação de dois níveis (2,5 e 5,0%) de levedura íntegra desidratada (Saccharomyces cerevisiae) e seus derivados, autolisado e parede celular, em dietas para juvenis de pacu (11,98 g e 8,5 cm). Foram avaliados o desempenho produtivo, a composição corporal e os parâmetros plasmáticos de juvenis de pacu. Utilizaram-se sete dietas isoproteicas (26% de proteína digestível por kg de ração) e isoenergéticas (3.100 kcal de energia digestível por kg de ração), cada uma com um nível de cada ingrediente-teste e mais uma dieta controle (sem adição de levedura). A suplementação da levedura e de derivados realizada durante 86 dias melhorou a eficiência alimentar e a utilização proteica pelos juvenis de pacu em comparação à dieta sem adição desses ingredientes.A composição de carcaça e os níveis plasmáticos (ureia, ácido úrico, proteína, cortisol e glicose) não são afetados pela suplementação dos ingredientes-teste.Palavras-chave: derivados de levedura, desempenho produtivo, Piaractus mesopotamicus, prebiótico, Saccharomyces cerevisiae Revista Brasileira de Zootecnia

“…The groups were completely randomized with a 2 × 2 × 3 factorial design: with and without supplementation, 2 stimulations (oily solution without S. agalactiae vaccine and vaccination) and 3 evaluation times (6, 24 and 48 h; n = 7 at each evaluation time). The feed (NRC 1993) contained isoprotein (32.0% DP), isoenergy (3200 kcal kg −1 of DE) and isophosphorus (3.0% P available phosphorus) with the same level of gross fiber (5.0%) (Baccarin & Pezzato 2001) The ingredients were finely ground (0.7 mm), homogenized, pelleted in a pellet mill (model 20A,California Pellet Mill) at 40°C and dried in a heated chamber with forced air circulation (55.0°C, 24 h). The pellets were fractionated into compatible diameters (6 mm) and stored at a temperature of −20.0°C.…”

This study evaluated the effects of dietary supplementation with 0.3% Saccharomyces cerevisiae yeast cell wall and of vaccination against Streptococcus agalactiae on the cellular component of acute inflammation induced in the coelomic cavity of Nile tilapia Oreochromis niloticus and on survival of the fish after challenge. A total of 84 tilapia of mean (± SD) weight 125.0 ± 1.5 g were distributed among twelve 310 l fiberglass tanks according to a 2 × 2 × 3 factorial design in the following manner: with and without supplementation; 2 stimulations (oily solution without S. agalactiae vaccine and vaccination); 15 d later all fish were intracoelomically challenged with 10 8 CFU ml -1 of a homologous strain of S. agalactiae, and evaluated after 6, 24 and 48 h, with 7 replicates. The fish received the non-supplemented or supplemented diet for a total of 77 d. The vaccination was performed on the 60th day, intracoelomically, as a single injection of 0.5 ml of the vaccine containing 10 8 CFU ml −1. Fifteen days later, all the fish were challenged with S. agalactiae by means of an intracoelomic inoculation of 10 8 CFU ml −1. No mortality was observed among the supplemented fish. The fish that were fed the non-supplemented diet and immunized with the bacterium presented a mortality rate of 28.5%. Among the non-supplemented and nonimmunized fish, the mortality rate was 38.09%. Supplementation, in both vaccinated and nonvaccinated fish, induced larger accumulations of thrombocytes, lymphocytes and macrophages at the inflammatory focus. The results suggest that supplementation with 0.3% yeast cell wall, in both vaccinated and non-vaccinated fish, improved the in flammatory response of the fish and protected against the challenge. Vaccination increased the defense response, but the effect was stronger when associated with supplementation with S. cerevisiae.
