“…The magnitude of the ADC of macronutrients and energy of the experimental diets was similar to those of comparable extruded salmon feeds that have been tested with Atlantic salmon under similar conditions (Arnesen & Krogdahl 1993; Johnsen et al . 1993; Aksnes 1995; Einen & Roem 1997; Thodesen & Storebakken 1998; Hillestad et al . 1999).…”

The effect of dietary protein to carbohydrate ratios (P/CH, weight percentage) of P34/CH21, P39/CH15 and P44/CH10 was studied in Atlantic salmon (Salmo salar L.) with respect to growth and feed conversion ratio (FCR) in one medium‐scale experiment (Experiment 1) and to slaughter quality in two production scale experiments (Experiments 2A and 2B). The dietary fat was maintained at 290 g kg−1 whereas the protein (fish meal) was exchanged with carbohydrate (wheat). Fish grown from approximately 1 to 4 kg were fed a restricted diet (iso‐energetic on gross energy basis) or to satiation. Nitrogen, fat, starch and energy digestibilities were measured in a separate experiment. There were slight tendencies for lower growth (P = 0.06) and for higher FCRs (P = 0.06) in Experiment 1, and a slight tendency for a lower dress‐out percentage in Experiments 2A and 2B (P = 0.10 and 0.20 respectively) with decreasing P/CH. The P/CH had no effect on the fat concentration of fillets, flesh colour or sexual maturation. The digestibility of starch decreased from 62.1% to 46.1% and the digestibility of energy from 84.9% to 79.5% when P/CH decreased from P44/CH10 to P34/CH21. Growth per unit digestible protein increased with decreasing P/CH. Feeding to satiation improved the growth but the FCR was higher than it was for restricted feeding. The calculated starch load per kg of fish growth increased with decreasing P/CH, whereas the effluent nitrogen decreased.

Two experiments were conducted to ascertain the utilization of different carbohydrate sources and different forms of starch present in bagrid catfish (Mystus nemurus) fry. The nutritional quality and starch forms of cornstarch, dextrin, broken rice, and sago flour were evaluated in a 4 × 2 factorial design. All diets were formulated to be isonitrogenous (400 g kg−1 crude protein) and isolipidic (150 g kg−1 crude lipid), fed to triplicate groups of bagrid catfish fry (initial weight 6.04 ± 0.04 g). Growth studies, enzymatic response and postprandial plasma glucose were observed. A two‐way anova (P > 0.05) analysis of the data obtained showed that the final body weight, specific growth rate (SGR) and food conversion ratio (FCR) were significantly affected by carbohydrate source, but not significantly affected by starch form. Fish fed broken rice and corn starch had similar SGR and FCR compared to fish fed with dextrin and sago flour. The postprandial plasma glucose trend in fish fed with corn starch and broken rice showed a gradual increase while sago flour and dextrin‐fed fish peaked at 2 and 3 h, respectively. Lipogenic enzyme (G6PDH) activity were more pronounced than gluconeogenic enzyme (ME) in M. nemurus irrespective of carbohydrate source and starch form. Therefore, we suggest that raw broken rice and corn starch are suitable carbohydrate sources in the M. nemurus diet.

“…In wheat, b-glucans are evenly distributed in the cell walls (20% b-glucans) of the grain (Thodesen and Storebakken, 1998). Fermentation with lactobacillus decreased b-glucan levels in both wheat and barley meals (Svihus et al, 1997a;Skrede et al, 2003).…”

An experiment was carried out to determine nitrogen-corrected apparent metabolizable energy (AMEn) values of processed wheat products with two levels of enzyme (0 and 0.5 g/kg) and five processing methods [control (C), water-soaking for 12 h (SO12h), 24 h (SO24h) and 48 h (SO48h) and fermentation with lactobacillus (FL)] in two species of poultry (cockerel and Japanese quail). In this study, each processing method group had six replications with two cockerels or four quails per replication. The results showed that the calculated AMEn values of processed wheat by different methods were as follows: C-12.61 and 12.60; SO12h-12.75 and 12.73; SO24h-12.80 and 12.79; SO48h-12.97 and 12.96; and FL-13.36 and 13.33 MJ/kg for cockerels and quails, respectively, indicating that fermentation improved AMEn values compared with the others. The mean AMEn of processed wheat with enzyme (13.12 MJ/kg) was significantly higher than that of processed wheat without enzyme (12.64 MJ/kg). However, there were no significant differences in the AMEn of processed wheat between cockerels and quails. The interaction between species and levels of enzyme in AMEn values was not significant. There was no significant difference (p > 0.05) in three-way interactions among species, levels of enzyme and wheat processing methods for AMEn values. In conclusion, the results of the experiment suggest that the FL was more effective processing method of wheat to obtain high level of AMEn values than the others, and the combination of enzyme and processing methods can increase the AMEn values compared with processing methods alone.
