“…According to Burrells et al (1999), same as for livers, lipid vacuoles Control -no lyophilized bovine colostrum (LBC) included; 10LBC -10% LBC included; 20LBC -20% LBC included. b Probability: Diet X Period -interaction diet x period.…”

“…On the other hand, Ostaszewaska et al (2005) reported the presence of large vacuoles in the digestive tract of rainbow trout Oncorhyncus mykiss and pacu Piaractus mesopotamicus, considered those findings a pathological reaction to the replacement of casein with soybean protein concentrate in the diet of these species, and suggested that these vacuoles can lessen intestinal nutrient absorption. Burrells et al (1999) and Sitjá-Bobadilla et al (2003) also consider that the presence of vacuoles in fishes' intestinal epithelium results in a loss of the mucosa integrity, which reduces fish specific growth rate and increase susceptibility to bacterial infection.…”

Histological responses of the intestine are key for evaluating nutritional value of feed ingredients, since the organ is not only the chief site of feed digestion and nutrient absorption but also plays an important immunological function. Histomorphological alterations were evaluated in the intestine of juvenile striped catfish, Pseudoplatystoma fasciatum, fed diets containing 0 (control), 10 or 20% inclusion of lyophilized bovine colostrum (LBC), as source of protein or bioactive peptides, for either 30 or 60 days. Fish fed 20LBC presented at 60d a distinct pattern of macrophages and, some of them, higher number of vacuoles in rectum mucosa. The thickness of the muscle layer (TML) in fish fed diets with LBC was higher in the first portion of medium intestine than fish fed 0LBC. All fish presented significant increase of TML in the second portion of medium intestine along feeding period, but fish fed 20LBC had smaller values of TML than those of fish fed 0 and 10LBC which might be related to the higher intestinal coefficient found for this group. The TML of rectum was higher just for fish fed 10LBC. Dietary LBC altered morphometrical features of juvenile striped catfish intestine and possibly induced inflammatory reaction in the rectal mucosa, as a function of level of inclusion, feeding period and segment of intestine analyzed.

Alterações histomorfológicas foram avaliadas no intestino de juvenis de cachara, Pseudoplatystoma fasciatum, alimentado com dietas contendo 0 (controle), 10 e 20% de inclusão de colostro bovino liofilizado (CBL) como fonte de proteína e peptídeos bioativos, aos 30 e 60 dias. Aos 60 dias, peixes alimentados com 20CBL apresentaram macrófagos de aspecto distinto e alguns, uma grande concentração de vacúolos na mucosa retal. A espessura da camada muscular (ECM) em peixes alimentados com CBL foi maior na primeira porção do intestino médio em relação àqueles alimentados com 0CBL. Ao longo do período experimental, todos os peixes mostraram aumento significativo na ECM na segunda porção do intestino médio, entretanto peixes do grupo 20CBL tiveram menores valores para a ECM do que os demais, o que pode estar relacionado com o maior coeficiente intestinal encontrado para este grupo. A ECM no reto foi maior apenas para os peixes alimentados com 10CBL. A inclusão de CBL na dieta do cachara alterou características morfométricas do intestino e, possivelmente, induziu uma reação inflamatória na mucosa retal em função do nível de inclusão, período de alimentação e porção do intestino analisada.

“…In many of these other studies, fish meal-based control diets were not used, or the concentrations of other non-soy protein sources were altered in the experimental diets [14][15][16]24,[48][49][50][51][52][53]. However, Barrows et al [54] suggested that soybean meal replacement for fish meal should be limited to less than 25% (or 10% to 15% dietary inclusion rates).…”

“…Inclusion rates for soybean meal in salmonid diets have typically been low because of the presence of trypsin inhibitors, lectins, saponins, poorly digestible carbohydrates (oligo-and polysaccharides), and other anti-nutritional factors [9][10][11][12]. Soybean meal in rainbow trout diets produces welldocumented deleterious effects on the distal intestine, such as morphological changes and subacute enteritis [12][13][14][15][16][17][18][19], as well as changes to intestinal microbial communities [15,16,18], and hepatic morphology [12]. Similar effects have been reported in Atlantic salmon Salmo salar [20][21][22][23].…”

The inclusion of PepSoyGen (PSG), a commercially-available fermented soybean meal product, was evaluated with juvenile rainbow trout, Oncorhynchus mykiss in an initial 70-day feeding trial, with a supplemental trial involving a subset of the experimental diets continuing for an additional 40 d. Six diets containing 0%, 10%, 20%, 30%, 40%, or 50% PSG, with the PSG directly replacing fish meal, were used in the first trial. There were no significant differences in weight gain or feed conversion ratio between the fish meal-based control diet and diets containing up to 30% PSG. However, weight gain was significantly reduced and feed conversion ratio significantly increased with the 40% and 50% PSG diets. No health assessment differences were observed in fish receiving any of the diets, and no evidence of gross gut inflammation was evident. There were no significant differences in weight gain or feed conversion ratio among the four dietary treatments ranging from 0% to 30% PSG which were fed for an additional 40 d after the initial 70-d trial (110 days total). Based on these results, juvenile rainbow trout diets can contain up to 30% PSG without any loss of rearing performance, thereby replacing at least 60% of the fish meal.

“…However, even when heat-treated, standard (solvent-extracted) and full-fat SBM-containing feeds were supplemented with limiting amino acids, decreased growth in salmonids was observed (Sandholm et al, 1976;Tacon et al, 1983;Davies and Morris, 1997). More specifically, SBM inclusion in the diet causes lower feed intake, weight gain, fecal dry matter, and energy and fat digestibilities in all salmonid species studied (Dabrowski et al, 1989;Olli et al, 1994b;Refstie et al, 1997 andStorebakken et al, 1998;Arndt et al, 1999;Burrells et al, 1999;. Dehulled SBM as the sole protein source may lead to growth arrest and increased mortality in rainbow trout, Oncorhynchus mykiss (Dabrowski et al, 1989;.…”
