Use of the bacteria Streptococcus faecium and Lactobacillus acidophilus, and the yeast Saccharomyces cerevisiae as growth promoters in Nile tilapia (Oreochromis niloticus)

Evaluation of Selected Dietary Probiotics on Growth Performance, Nutrient Utilization and Body Carcass Composition of Mystus Cavasius (Hamilton, 1822) Fry

“…Significantly higher (P <0.05) PER was recorded in fish maintained on the probiotic Bactocell supplemented diets than the other groups in the present feeding trial, corroborating the results of other previous studies. This results also agree with those obtained from previous studies by other authors (Lara-Flores et al, 2003), where growth, PER was reported to be better in Nile Tilapia fed diets supplemented with probiotics than those fed a diet without probiotics supplementation. Similar observations have been reported on African cat fish (Al-Dohail et al, 2009;Ayoola et al, 2013).…”

“…The results are in agreement with the findings on Nile tilapia (Lara-Flores et al, 2003;Mohamed et al, 2007), African cat fish (Al-Dohail et al, 2009;Ayoola et al, 2013) and common carp (Noh et al,1994;Yanbo and Zirong, 2006). Protein utilization, measured in terms of PER, in the study increased to some extent with probiotics-supplement diets with highest (P <0.05) observed in T1 group.…”

“…In the study, fish fed diets containing probiotics supplement showed higher body protein and lipid content than the control diet. The use of probiotics in the diet of Nile tilapia (Oreochromis niloticus) was amended with a probiotic Streptococcus strain, increasing significantly the content of body crude protein and crude lipid in the fish, also weight has increased from 0.154 g to 6.164 g in 9 weeks of culture (Lara-Flores et al, 2003).…”

Probióticos em dietas para tilápia do Nilo durante a reversão sexual

“…Comparativamente com os resultados obtidos por TACHIBANA et al (2008), em que encontraram valores superiores aos encontrados no presente trabalho estudando a densidade de estocagem durante a fase de reversão sexual, observaram que o crescimento específi co variou entre 14 e 18%. No entanto, LARA-FLORES et al (2003), estudando a utilização de duas bactérias e um fungo como promotores de crescimento em tilápia do Nilo, obtiveram o percentual máximo 6,16% no crescimento específi co, sendo ainda inferior aos valores obtidos neste estudo. Provavelmente, fatores ambientais como a temperatura da água abaixo do recomendado podem ter infl uenciado no crescimento dos alevinos na fase de reversão sexual durante o inverno no Oeste do Paraná.…”

Yeast: World’s Finest Chef

“…That reaction can be related to β-glucans, nucleic acids as well as mannan oligosaccharides [93]. Brewer's yeast may serve as an excellent health promoter for fish culture as even when administered for relatively long periods is able to enhance immune responses as well as growth of various fish species, without causing immunosuppression [94,95]. Furthermore, the relative high levels of nucleic acid nitrogen present (mostly in the form of RNA) that in humans and most monogastric animals can became toxic if taken in excess, as the capacity of excretion of the uric acid formed is limited [96], in fish does not happen due to their very active liver uricase [97].…”
