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 several aquatic species replacement of FM with vegetable protein sources such as SBM resulted in lower weight gain (Francis et al 2001) and histopathological damages (Aslaksen et al 2007;Kraugerud et al 2007;Krogdahl et al 2003), the magnitude of which depends on the source and level of replacement (Merrifield and Olsen 2011). Thus, the change from FM to soybean meal generally causes several metabolic and health challenges for the farmed aquatics (Heikkinen et al 2006).…”

This study aimed to evaluate the effect of soybean meal and multienzyme supplementation on intestinal histopathology of beluga sturgeon (Huso huso). Nine diets were formulated (40% crude protein, 13% crude fat and 4150 kcal/kg gross energy) in which fish meal was replaced by soybean meal at 0, 40 and 80% supplemented or not with 1 or 2 g/kg of multienzyme Kemin. Fish (initial weight of 820 g) were fed on experimental diets four times daily at 1% body weight for 12 weeks. From histological analyses, intact villus with normal mucosa was found in the FM group, representing the presence of intact epithelium. Supplementation of enzyme at both levels and soybean meal (alone) in the diet resulted in histopathological alterations in the intestine including mild immune cells infiltration, villus blunting, villus fusion, mononuclear immune cells infiltration as well as necrosis. Soybean meal decreased the length of villuses in the proximal and distal intestines (P \ 0.05). Enzyme was not able to ameliorate the derangements induced by 80% replacement level of fish meal with soybean meal (treatments SB80E1% and SB80E2%). However, coadministrating of the enzyme at both levels with 40% soybean meal (treatments SB40E1% and SB40E2%) was able to inhibit the soybean meal-induced histopathological impairments.

“…Lupin seeds have been used successfully as a replacement for ¢sh meal in aquaculture feeds of salmonids and other marine ¢sh (De la Higuera, Garcia-Gallego, Sanz, Cardenete, Suarez & Moyano 1988;Robaina, Izquierdo, Moyano, Socorro, Vergara, Montero & Fernandezpalacios 1995;Burel, Boujard, Corraze, Kaushik, Boeuf, Mol, Van der Geyten & Kuhn 1998;Burel, Boujard, Kaushik, Boeuf,Van der Geyten, Mol, Kuhn, Quinsac, Krouti & Ribaillier 2000;Carter & Hauler 2000;Farhangi & Carter 2001;Aslaksen, Kraugerud, Penn, Svihus, Denstadli, Jorgensen, Hillestad, Krogdahl & Storebakken 2007;Glencross, Hawkins, Evans, Rutherford, Dods, McCa¡erty & Sipsas 2008).

The e¡ect of dietary inclusion of whole grain white lupin (Lupinus albus) on growth performance, histology, muscle fatty acid composition and nutrient digestibility was investigated in an 11-week growth and a 4-week digestibility trial with rainbow trout (initial body weight of 54.0 AE 6.2 and 181.9 AE 3.4 g respectively). Four experimental extruded diets were formulated to contain 0%, 30%, 40% and 50% of whole grain lupin and fed to triplicate groups of ¢sh twice a day until apparent satiation. Faeces were collected daily from each digestibility tank by decantation. No signi¢cant trends were observed with respect to growth, feed utilization, apparent digestibility coe⁄cients or whole-body composition (P40.05). Conversely, increasing levels of dietary lupin led to signi¢cant decreases in the Hepatosomatic index (R 2 50.75, Po0.05) and slight lipid in¢ltration into hepatocytes and enterocytes. Muscle fatty acid compositions were slightly a¡ected by the dietary treatment. Polynomial regression of dietary inclusion of lupin and muscle fatty acid concentrations showed an increase in C18:1n-9, C18:2n-6 and C18:3n-3 and a decrease in C20:5n-3 with increasing dietary lupin level. These results demonstrated that whole grain lupin can be included up to 50% in commercial rainbow trout diets without negative e¡ects.
