“…Thus, there is a need to control the disease outbreaks in this sector. A concept of a functional feed is an emerging paradigm in aquaculture industry to develop nutritionally balanced diets with functions to control the diseases and culture water system by feed additives (Li and Gatlin 2004;Lee et al, 2013;Wongsasak et al, 2015).…”

An 8-week feeding trial was conducted to study the effect of dietary supplementation of a biofloc powder on growth performance and non-specific immune response of Litopenaeus vannamei. Seven experimental diets were prepared with supplementation of graded levels of dried biofloc powder by 0, 0.5, 1.0, 2.0, 4.0, 6.0, and 8.0% (designated as Con, BF0.5, BF1, BF2, BF4, BF6, and BF8, respectively). Triplicate groups of shrimp (1.01 ± 0.01 g) were hand-fed with one of the diets four times a day. At the end of the feeding trial, significantly (P ˂ 0.05) higher growth performance and feed utilization were obtained in BF4 groups compared to those fed the Con diet. The innate immunity of shrimp was improved by the dietary supplementation of biofloc. Dietary inclusion of biofloc at the level of 4.0% significantly increased disease resistance of shrimp against Vibrio harveyi. The results indicate that biofloc might be used as a dietary supplement for growth performance, innate immunity and disease resistance of Pacific white shrimp.

“…O mananoligossacarídeo (MOS) proveniente da parede celular da levedura Sacharomyces cerevisiae tem sido utilizado em dietas com o objetivo de melhorar a conversão alimentar, a integridade da mucosa intestinal e a saúde dos peixes, resultando em melhor ganho econômico (Li & Gatlin III, 2004). É um prebiótico que possui na sua composição química cerca de 40% de β-glucanos, 40% de α-mananos, 28% de proteínas, 7% de lipídeos, 3% de substâncias inorgânicas e 2% de hexosaminas e quitina.…”

RESUMO -Este experimento foi realizado para avaliar níveis crescentes de mananoligossacarídeo (MOS) na dieta de larvas de tilápias-do-nilo (linhagem Supreme ® ) na fase de reversão sexual durante 30 dias. Larvas de tilápia-do-nilo (n=1500, P=0,01 g ± 0,001 g) foram distribuídas aleatoriamente em 30 tanques de 100 litros. Os peixes foram distribuídos em delineamento inteiramente casualizado, composto por seis tratamentos e cinco repetições. A dieta controle (isenta de MOS) foi elaborada para conter aproximadamente 35% de proteína bruta e 3.100 kcal de ED/kg. As demais foram suplementadas com 0; 0,15; 0,30; 0,45; 0,60 e 0,75% de MOS em substituição ao milho da dieta controle. Com o aumento nos níveis de MOS nas dietas, foi observado aumento linear sobre o comprimento do intestino, a altura das vilosidades intestinais e a densidade dos vilos. Não houve diferença na composição corporal, no ganho em peso, no peso final, no comprimento final, no fator de condição, na taxa de sobrevivência e no número de células caliciformes do intestino das larvas. Os níveis de MOS tiveram efeito quadrático sobre a conversão alimentar, cujos melhores resultados foram obtidos com 0,34% de MOS. A utilização de MOS no nível de 0,34% em dietas para larvas de tilápia-do-nilo melhora a conversão alimentar e promove aumento do comprimento do intestino, da altura das vilosidades e da densidade de vilos intestinal.Palavras-chave: desempenho, mucosa intestinal, peixe, prebiótico Mannanoligosaccharides in diets for tilapia larvaeABSTRACT -This experiment was conducted to evaluate increasing levels of mannanoligosaccharides (MOS) in the diet of Nile tilapia larvae (Supreme ® ) at the sex reversal stage for 30 days. Nile tilapia larvae (n = 1500, p = 0.01 ± 0.001 g), were randomly distributed in 30 tanks of 100 liters each, for 30 days. The fish were distributed in a randomized design with six treatments and five replicates. The control diet (no MOS) was elaborated to contain approximately 35% of crude protein and 3,100 kcal DE/kg. Mannanoligosaccharides were included in the other diets, replacing corn, at levels of 0, 0.15, 0.30, 0.45, 0.60 or 0.75%. Linear increase in the intestine length, intestinal villous height and villi density was observed with the dietary MOS increase. No differences in body composition, weight gain, final weight, final length, condition factor, survival rate or number of goblet cells of the gut of the larvae were observed. A quadratic effect on feed conversion ratio was observed with the MOS inclusion and the best value was estimated with 0.34%. Dietary MOS inclusion at 0.34% improves feed conversion and increases intestine length, villi height and density of intestinal villi in diets for Nile tilapia larvae. IntroduçãoNo Brasil, tilápia-do-nilo (Oreochromis niloticus) é a espécie exótica mais criada em tanques-rede. Em 2004, a produção de tilápias no Brasil foi de 26% do total produzido na aquicultura nacional, e o país respondeu por 64% da produção total desta espécie de peixe (Ostrensky et al., 2008).Por apresentar e...

“…Conflicting results between the study of Fracalossi and Lovell (1995) and this study are difficult to explain, because there were multiple differences in the proximate and ingredient composition of the purified diets in their study v. the practical diets used in the current study. Mixed results regarding growth and feed efficiency of fish fed the dairy/yeast prebiotic used in this study have been obtained for hybrid striped bass (Li and Gatlin, 2004), red drum (Burr et al, 2009;Buentello et al, 2010), rainbow trout (Sealey et al, 2007), golden shiner (Lochmann et al, 2011) Total n-3 fatty acids included 18:3n-3.…”

Channel catfish raised in the southern United States require two growing seasons to reach market size. Growing seasons are separated by a cool period of about 3 months when feed intake and growth are greatly reduced. A cool-weather feeding strategy to improve feed intake, growth or health of catfish might improve survival and reduce the time needed to achieve market size. We conducted a feeding trial with channel catfish at a suboptimal temperature (15°C) to determine the effects of supplementing diets with either a dairy/yeast prebiotic or flaxseed oil (high in 18:3n-3) compared with a control with soybean oil (high in 18:2n-6). The trial was conducted in recirculating systems with 1140-l tanks containing 100 fish each (mean initial weight 61.4 g ± 0.43 s.e.m.). A 28%-protein basal diet was supplemented with 20 g/kg cellulose and 20 g/kg soybean oil (SBO, control), 20 g/kg cellulose and 20 g/kg flaxseed oil (FLAX) or 20 g/kg of a dairy/yeast prebiotic and 20 g/kg soybean oil (PREB). Fish were fed once daily to satiation and weighed every 3 weeks to track growth. Hematology, non-specific immune responses, proximate and fatty acid composition of muscle were determined to assess diet effects. Catfish-fed FLAX or PREB had higher weight gain, feed consumption and lysozyme activity than fish fed SBO. Total n-3 fatty acids in muscle were higher in fish fed SBO or FLAX than those fed PREB. Total n-6 long-chain polyunsaturated acids were higher in muscle of fish fed PREB than those fed SBO. Fatty acids in the PREB and SBO diets were similar, so the PREB appeared to increase elongation and desaturation of n-6 fatty acids in muscle. Flaxseed oil and the dairy/yeast prebiotic both have potential to increase catfish performance at a low temperature.
