“…This is in line with Madalla () that histopathological intestine was unaffected by morning leaf meal, cassava leaf meal and cassava root meal and Aanyu et al () that sunflower cake and cotton seed cake did not change intestinal fold length and numbers. Likewise whole cereal meal had no effect on intestinal morphology in gilthead seabream ( Sparus aurata ) (Couto, Peres, Oliva‐Teles, & Enes, ). Also in Atlantic salmon, intestinal morphology was unaffected by cellulose, native and extruded NSPs (Kraugerud et al, ).…”

The present study assessed the effect of different feed ingredients on nutrient apparent digestibility coefficients (ADC), nitrogen/energy balance and morphology changes in the intestine of Nile tilapia; using a control diet and six test diets, in which the following six ingredients were included at 30%: hydrolysed feather meal (HFM), soybean meal (SBM), rice bran (RB), rapeseed meal (RM), sunflower meal (SFM) and dried distillers grains with solubles (DDGS). The proximal, middle and distal intestine was processed for quantitative histology counting the number of goblet cells (GC), and measuring the thickness of lamina propria (LP) and submucosa (SM). The study showed that the ADC of protein in raw materials were highest in SBM (92.2%), followed by SFM (90.2%), DDGS (89.2%), RM (87.8%), HFM (86.9%) and RB (84.0%). The nutrient ADCs had no correlation with intestinal morphology changes. Only the SBM diet caused noticeable changes in intestinal morphology such as an increase the thickness of SM and LP and the number of GC. The diet composition, however, altered the protein efficiency and the maintenance energy requirement. Protein retention efficiency was the lowest in fish fed HFM and the highest in RB. The highest maintenance energy requirements were observed in HFM and SBM treatments.

“…(Gatlin et al 2007). It also reported that corn starch has lower ADCs than other cereal meals because of bigger starch granules and higher amylose/amylopectin ratio (NRC 2011;Couto et al 2016), which may be contributed to the lower ADCs of protein and lipid in fish fed with the 1.8 CHO:L ratio diet. In the other hand, raw starch (non-gelatinized starch) inhibits the starch hydrolysis, accelerates the passage of chime through intestine and reduced the availability of time for nutrient absorption, which reduces the protein and lipid digestibility (Sinha et al 2011;Amin et al 2014).…”

Four isonitrogenous diets containing different carbohydrate:lipid (CHO:L) ratios (0.3, 0.6, 1.1 and 1.8) were tested in triplicate groups (16 fish per replicate) of silvery‐black porgy juveniles for 8 weeks. Growth performance was not affected by different dietary CHO:L ratios (P > 0.05); however, the viscerosomatic index, the intraperitoneal fat, whole‐body lipid, energy and n‐3 long chain polyunsaturated fatty acids levels increased with decreasing dietary CHO:L ratios (P < 0.05). Fish fed with 1.8 CHO:L diet had the lowest apparent digestibility coefficients of protein and lipid, as well as the lowest plasma haemolytic and lysozyme activities (P < 0.05). Red blood cell counts and plasma glucose levels were higher in fish fed with 1.1 and 1.8 CHO:L ratio diets than in the other groups (P < 0.05). Plasma alkaline phosphatase and alanine aminotransferase, as well as the level of lipid peroxidation and total antioxidant capacity in the liver and plasma increased as dietary CHO:L ratios decreased (P < 0.05). The results of the current study indicated that the diets with CHO:L ratios between 0.6 and 1.1 are optimal for silvery‐black porgy, whereas higher ratios may result in hyperglycaemia and immune suppression, and lower CHO:L ratios may lead to oxidative stress and liver dysfunction.

“…More recently, Aanyu et al (2014) showed also that a diet with sunflower and cotton seed cake caused no significant negative changes in the number and length of intestinal folds. Couto et al (2016) found the inclusion of 30 % whole cereal meal in diets for gilthead seabream (Sparus aurata) did not affect the intestinal morphology. Also in Atlantic salmon, the intestinal morphology were not affected in fish fed diets containing either cellulose, native or extruded NSPs (Kraugerud et al, 2007).…”
