“…These data are consistent with studies in rainbow trout (Cheng and Hardy, 2002) and channel catfi sh (Robinson and Daniels, 1987;Robinson and Brent, 1989). After a 3-year rainbow trout feeding trial with 58.8% dietary CM, total muscle gossypol content was <1 μg/g wet sample, which is far lower than the limit set by the FDA (450 mg/kg) (Lee et al, 2006). Based on these results, humans can safely consume fi llets produced by fi sh fed CM-containing diets.…”

“…The same growth performance and feed utilization were observed under these conditions as fi sh fed a complete FM diet during outdoor culture. Large rainbow trout (1.5 year old adults and broodstock) fed CM-containing feed for more than 9 months do not show depressed growth (Dabrowski et al, 2000;Blom et al, 2001;Rinchard et al, 2003;Lee et al, 2006). In contrast, lower growth was observed in both sexes of mature tilapia ( Oreochromis sp.)…”

Cottonseed meal (CM) was used at up to 36.95% content in the diet (replacing 60% of dietary fi sh meal protein) without any negative eff ects on growth performance of pre-adult grass carp (initial body weight, 761 g) under outdoor conditions. A culture trial was conducted in net cages installed in a large concrete pond. Seven isonitrogenous and isoenergetic diets containing a gradient of CM concentrations (0, 12.2%, 24.4%, 36.6%, 48.8%, 54.8%, and 61.0%) as replacement for dietary fi sh meal protein (0, 20%, 40%, 60%, 80%, 90%, and 100%) were formulated. Dietary non-resistant starch (from maize) was inverse to dietary CM. Growth performance and feed utilization of fi sh fed the diets containing CM replacing 0-40% fi shmeal protein were not aff ected after the 6-week feeding trial. Accumulation of hepatopancreatic total gossypol in the hepatopancreas was signifi cantly correlated with free gossypol content in the diets (HTG=88.6+1.5×DFG, R 2 =0.89, P <0.05). Intestinal α-amylase and γ-glutamyl transpeptidase activities rose along with increasing dietary CM level. The structure of the mid-intestinal tissues and the ultrastructure of the enterocyte microvilli were normal when dietary CM was <36.6% (60% protein replacement). Increasing dietary CM content increased serum alanine aminotransferase levels but decreased serum alkaline phosphatase, cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and albumin ( P <0.05).

“…Owing to its high protein value for animals (Alford et al, 1996) as well as low market price in comparison with other legumes and fish meal, cottonseed meal (CSM) consequently has an immense potential for incorporation in high-protein aquafeeds. Lee et al (2006) summarized a series of studies in rainbow trout where CSM replaced fish meal entirely over the 3-year period without significantly impacting growth rate of female and male rainbow trout. In the study of Robinson and Li (1994), channel catfish, Ictalurus punctatus, were fed to satiation a diet containing 51% CSM with supplemented lysine (0.65%).…”

ABSTRACThe present experiment was conducted to evaluate the effect of α-tocopherol as an antioxidant for avoiding the side effects of incorporation of cottonseed meal (CSM) in the diet of the Nile tilapia as a replacer of fish meal (FM). Two diets were prepared; the first one contained fish meal and was considered as a control, in the second diet, FM was completely replaced by CSM. The second diet was divided into ten parts, the first one is a control and the other 9 diets were enriched with increased levels of vitamin E (1, 5, 10, 15, 20, 25, 30, 35 and 40 times of gossypol in CSM). Each diet was offered in three aquaria (3 replicates for each diet) and each aquarium was stocked with 25 fish (2.0-2.1g). Results are summarized in the following: -The highest average body weight (9.91 g) was recorded for the control group fed on the basal diet (contained FM) and the lowest BW (5.66 g) was obtained for fish fed the diet D2 in which FM was completely replaced by CSM without vitamin E. Incorporation of vitamin E in the experimental diet significantly improved the BW. Similar trend was observed for the other growth performance parameters body length (BL), weight gain (WG) and specific growth rate (SGR). -The best feed conversion ratio (FCR) was recorded for fish group fed on the diets D1 and D3 which significantly differed from values recorded for the other treatments. The worst FCR was recorded in fish group fed on the diet D2 in which FM was completely replaced by CSM without addition of vitamin E. Incorporation of vitamin E in the experimental diets improved FCR specially fish group fed on the diet D3. -Protein content of the whole fish body ranged between 41.33 to 50.97% and the differences were significant. Fat content of fish fed the diet D2 significantly higher than those obtained for fish fed the other groups. Compared to the two control diets D1 and D2 all vitamin levels in the experimental diets increased ash content of the fish whole body and the graded levels of vitamin E in the diets significantly altered the ash content of tilapia fish. -The highest values for hematocrite (Ht) and haemoglobin (Hb) were obtained for fish fed on the control diet (D1). Incorporation of vitamin E in the experimental diets at increasing levels significantly affected Hb and Ht. Compared to the control group (Diet1) aspartate transaminase (AST) and alanine transaminase (ALT) levels significantly increased fish groups fed on the other experimental diets.

“…Trabalhos relacionados à avaliação do efeito da inclusão de diferentes fontes proteicas no desempenho reprodutivo são escassos, no entanto pode-se destacar o trabalho de PELISSERO et al (1991), que examinaram o efeito estrogênico da dieta de farelo de soja no processo de vitelogênese no esturjão da Sibéria (Acipenser baerii) e relataram que níveis de vitelogenina aumentaram nos peixes alimentados com dietas contendo 30 g/100 g de farelo de soja. LEE et al (2006), ao avaliar o efeito a longo prazo da inclusão do farelo de algodão no desempenho produtivo e reprodutivo da truta arco-íris (Oncorhynchus mykiss), concluíram que a suplementação de 58,8 g/100 g de farelo de algodão não teve efeitos prejudiciais no crescimento dos peixes, contudo, o desempenho reprodutivo dos machos e das fêmeas foi prejudicado no nível acima de 29,4 g/100 g de farelo de algodão.…”

RESUMOAvaliou-se a influência dos níveis de grãos secos de destilaria com solúveis (DDGS) no desempenho reprodutivo de lambaris. Foram elaboradas dietas contendo 0%, 10%, 20% e 30% de DDGS. Os peixes foram estocados durante 150 dias em 16 tanques, com biofiltro, sistema individual de aquecimento e recirculação de água, na densidade de 0,3 peixe.L -1 . Foram determinados: fator de condição corporal, índice gonadossomático, volume dos ovos, fertilidade inicial, fertilidade inicial relativa, taxa de fertilidade, índice de desova, fertilidade final, fertilidade final relativa, taxa de eclosão e de sobrevivência das larvas, diâmetro dos ovos e do vitelo e comprimento das larvas. Realizaram-se também histologia das gônadas das fêmeas e dos machos e avaliação do sêmen. Os dados foram submetidos à análise de variância, regressão e teste de tendência. A adição de DDGS nas dietas afetou a fertilidade inicial nas fêmeas, o peso, o comprimento total e o padrão dos machos (P<0,05). Para as outras variaveis não foram observadas diferenças (P>0,05). Não foram evidenciadas diferenças entre as estruturas morfológicas dos ovários, mas os testículos dos peixes alimentados com dieta de 30% de DDGS apresentaram células espermáticas em abundância. O DDGS pode ser usado como alternativa proteica, sem gerar prejuízos ao desempenho reprodutivo.Palavras-chave: peixe; alternativa proteica; reprodução. REPRODUCTIVE PERFORMANCE OF LAMBARIS FED WITH DISTILLERY DRIED GRAINS ABSTRACTThis research was carried out to investigate the influence of dietary inclusion of distillers dried grain with solubles (DDGS) on reproduction performance of lambari. Four diets were prepared containing 0%, 10%, 20%, and 30% of DDGS. Fishes were stocked in 16 tanks, provided with biofilter and single system of water recirculation and heating, density were 0.3 fish.L -1 , during 150 days. Were determinate: body conditional fator, gonadossomatic index, egg volume, initial fertility, relative initial fertility, fertility rate, spawning rate, final fertility, final relative fertility, hatching and survival rate of larvae, eggs diameter and length of larvae. It was made histology of the gonads of females and males and evaluation of semen. The data were subjected to analysis of variance, and regression trend test. The addition of DDGS in the diets affect the initial fertility in females, the weight, the total length and pattern of males (P < 0.05). For the remaining variables no differences were found (P > 0.05). Were not highlighted differences between the morphological structures of the ovaries, but the testicles of fish fed diet of 30% of DDGS presented abundant sperm cells. The DDGS can be used as alternative protein without generating losses in reproductive performance.
