“…Moreover, dietary fibre remained mostly unchanged after passage through the gastrointestinal tract, with an apparent moderately or lack of fermentation. Indeed, it has been reported in several studies that most of the hemicellulose fraction is not digested by fish (Davies ). In the present work, small amounts of rapeseed fibre were identified by a direct visual observation within faeces from RM‐fed C. auratus and S. aurata .…”

Influence of lupin and rapeseed meals on the integrity of digestive tract and organs in gilthead seabream (Sparus aurataL.) and goldfish (Carassius auratusL.) juveniles

Two rearing trials were conducted to evaluate the effects of dietary lupin (LM) and rapeseed (RM) meals in gilthead seabream (Sparus aurata L.) and goldfish (Carassius auratus L.) juveniles. Each plant meal was incorporated at the rate of 200 g kg À1 in two distinct diets, which were compared with a fishmeal-based diet as control. After 1 month, the two plant diets did not influence the whole body growth, but the digestive systems were affected. The splenosomatic index was reduced with two plant meals in goldfish and with RM in seabream. The hepatosomatic index was only reduced in LM-fed seabream. Cellular characteristics were also affected. The largest liver cells were observed in RMfed goldfish suggesting changes in metabolic function. The LM and RM diets stimulated in seabream, especially the reaction in haematopoietic tissues with the proliferation of melano-macrophages centres, and a tendency for elongated villus height in the anterior intestine thus that possibly compensated for a reduction in digestive function. Such adaptive structural modifications and the absence of degenerative signs allowed concluding that the integrity of the digestive system was maintained in fish fed plant meals.

“…The use of cellulose as an inert filler in experimental fish diets has been criticized by Hilton et al (1983) who found that dietary concentrations of 10 and 20% cellulose depressed growth of rainbow trout when the added cellulose diluted the basal diet as a whole. Davies (1985), on the other hand, reported that up to 20% of cellulose could be inserted into a diet formulation for trout, with the necessary adjustments for nutrient balance, without an adverse effect on growth. Cellulose was employed in the present experiment in a similar way to its use by Davies (1985).…”

Juvenile chinook salmon of three strains responded to inclusion of 28.7% of gelatinized starch in the diet with different degrees of reduction in growth rate and feed efficiency relative to control fish of the respective strains fed a low-starch, high-lipid diet of similar protein (46%) and estimated metabolizable energy content (16 mJ/kg). The productive protein value of the diet was not reduced to the same extent by the high intake of starch. Carcasses of fish fed the high-starch diet contained higher concentrations of protein and lower concentrations of lipid than control fish. The accumulation of liver glycogen in response to the high-starch diet differed among strains. Glucose tolerance curves also varied among strains but were poorly correlated with plasma concentrations of insulin. Tolerance to glucose loading was improved in fish previously fed the high-starch diet.

“…The majority of monogastric animals including fish are incapable of degrading dietary fibre. However, carnivorous fish such as rainbow trout ( Oncorhynchus mykiss ) may be capable of degrading fibre in the form of cellulose to a limited degree depending on the bacterial population in intestinal microbiota (Davies ). The dietary fibre digestion is enhanced by several mechanisms such as microbial fungal activities and fermentation (Bailey ; Demigné & Rémésy ; Noblet & Le Goff ; Glencross ).…”

Haemato-immunological and serum biochemical parameters, intestinal histomorphology and growth performance of rainbow trout (Oncorhynchus mykiss) fed dietary fermentable fibre (Vitacel^®)

The aim of this study was to investigate the effects of dietary fermentable fibre (Vitacel®) on haemato‐immunological and serum biochemical parameters, intestinal histomorphology, growth performance and proximate body composition of rainbow trout (Oncorhynchus mykiss). One hundred and twenty fish (81.65 ± 1.49 g) were fed diets containing 0 and 10 g kg−1 fermentable fibre (Vitacel®) for 50 days. At the end of feeding trial, growth performance parameters were significantly improved in fermentable fibre (Vitacel®)‐fed fish. Although feeding on fermentable fibre (Vitacel®)‐supplemented diet had no remarkable effect on haematological parameters (RBC, Htc and Hb) (P > 0.05), white blood cell (WBC) count and monocyte level were significantly affected (P = 0.040 and P = 0.020, respectively). In case of serum biochemical parameters, a significant increase and decrease were observed in serum total protein (P = 0.040) and cholesterol level (P = 0.000), respectively. Also, lysozyme level was significantly increased following administration of Vitacel® in diet (P = 0.006). Histomorphological evaluations revealed that villus length (P = 0.004) and tunica muscularis thickness (P = 0.000) were significantly higher in fermentable fibre (Vitacel®)‐fed fish. These results indicate that fermentable fibre can be considered as a dietary supplement for improving the health status and performance of rainbow trout.
