This fundamental study was undertaken to evaluate the nutritional value of Canola rapeseed meal which has been increasingly used as a by-product with the demand for the food oil resource. To compare the nutritive values among rapeseed meal and soybean meal, two experiments were carried out by using rats. One was a digestibility test of rapessed meal and the other was the growth rate of rats for 21 days. The chemical compositions , blucosinolate and amino acids of defatted repeseed meal and defatted soybean meal were analyzed. After one week feeding, nitrogen excretion in rats was measured to study FER, PER , TD , BW , and NPU of the meals. The amount of crude proteins in defatted rapeseed meal and defatted soybean meal were 45.5% and 37.9%. The glucosinolate content of defatted rapeseed meal was 0.04% . The body weight gain of defatted rapeseed meal was not signficantly different from that of defatted soybean meal (p>0.01). After one week feeding, there was no significant differencess in organ weight and serum components between two groups(p>0.01). It was presumed that the rapeseed meal has enough possibility for developing food to use as a protein source like a soybean meal protein. However, more careful experiments are needed to clarify the nutritional value of rapeseed meal of Canola since the lipids composition of blood tended to be different when the rapeseed meal and soybean meal were used.

A feeding trial was conducted to evaluate dietary protein sources replacing fish meal for parrot fish, Oplegnathus fasciatus. A control diet with white fish meal as a protein source was included. White fish meal in the isonitrogenous diet was replaced with each of 22% meat meal, 17% blood meal, or 31% soybean meal. Triplicate groups of 25 fish initially averaging 26 g were fed four experimental diets for 7 weeks in a flow-through tank system. Weight agin and feed efficiency in fish fed diet containing 17% blood meal (this diet also contained 45% white fish meal) were not significantly different from those in fish fed the control diet (P>0.05). Fish fed diet containing 22% meat meal had lower weight gain and feel efficiency than those of fish fed the control diet (P<0.05). weight gain of fish fed diet containing 31% soybean meal was not different from that of fish fed the control diet, but feed efficiency of fish fed the diet was lower than that of fish fed the control diet.

A series of four experiments was conducted to compare nutritional values of decorticated sunflower meals against soybean meal, in diets for pigs from weaning (Exp. 1 and 2) to finishing (Exp. 3 and 4). All experimental diets were prepared compensating for the energy content by using vegetable oil and the lysine content was matched using synthetic L-Lysine HCl. Twenty-one day old pigs were fed either corn-soybean meal based diet (CSBM) or corn- twice-decorticated sunflower meal based diet (CDSM) for four weeks (Exp. 1). There was no difference in performances between treatment groups. In Exp. 2, corn-non-decorticated sunflower meal based diet (CNSM) was added to the existing two treatments. Twenty-one day old pigs were fed three experimental diets for four weeks. Pigs fed CNSM had a lower weight gain and feed intake than other treatments (p<0.05). There was no difference between pigs fed CSBM and CDSM (Exp. 2). Growth performance of growing pigs was also greater (p<0.05) in pigs fed corn starch-twice- decorticated sunflower meal based diet (CSDSM) than pigs fed corn starch-non-decorticated sunflower meal based diet (CSNSM) during the eight week feeding trial (Exp. 3). There was no difference between pig fed corn starch-soybean meal based diet (CSSBM) and CSDSM (Exp. 3). In Exp. 4, growing pigs were fed three experimental diets (CSBM, CDSM, and barley-twice- decorticated sunflower meal based diet; BDSM) until the slaughter. There was no difference in growth performance of pigs during growing and finishing periods among treatments. However, pigs fed CSBM had a higher carcass dressing percentage (p<0.05) than pigs fed CDSM and BDSM. Pigs fed BDSM diet had a lower fat tissue percentage than other groups (p<0.05). The twice-decorticated sunflower meal can be used as a substitute for soybean meal in pig diets. The performances of piglets and growing-finishing pigs were not affected when soybean meal was replaced by twice-decorticated sunflower meal. This substitution needs the contribution of synthetic lysine and vegetable oil as sources of complementary nutrients to match the nutrient profile.

This study was conducted to investigate the effects of dietary supplementation of cottonseed and soybean meal on growth performance of juvenile olive flounder (Paralichthys olivaceus). Nine hundred fish $(0.74{\pm}0.11g)$ in the early juvenile stage were randomly divided into 15 groups, and 3 groups were fed one of five isonitrogenous (56% CP) and isocaloric $(16.3\;MJ\;kg^{-1})$ diets replacing 0, 10, 20, 30, and 40% of fish meal protein by equal proportion (1:1, w:w) of cottonseed and soybean meal (CS) (designated by Control, CS10, CS20, CS30, and CS40, respectively). A solvent extracted cottonseed meal containing high crude protein (44%) and low fiber content (<12%) was used in this study. After 10 weeks of feeding trial, the growth offish fed diets CS10, CS20, and CS30 were not significantly (P>0.05) different compared to that of fish fed the control diet. However, diet CS40 exhibited significantly lower (P<0.05) growth performance than the control diet. No differences were observed in whole body composition of fish fed all the experimental diets. This study indicates that mixture of cottonseed and soybean meal with lysine and methionine supplementation can replace up to 30% fish meal protein in diet for olive founder at the early juvenile stage. However, we suggest that 20% of fish meal protein replacement by cottonseed (10%) and soybean (10%) meal can be the optimum level for commercial use in safety according to the growth performances.

We examined the effect of substituting squid meal and macroalgae with soybean meal in a commercial diet on the growth and body composition of juvenile abalone Haliotis discus hannai. We randomly distributed 2310 juvenile abalone into 33 rectangular plastic containers and fed them five experimental diets in triplicate as follows. The control diet (Con) consisted of 12% squid meal, 8% corn gluten and 20% soybean meal as protein source, wherein 10% ${\alpha}$-starch, 20% wheat flour, and 5% dextrin were carbohydrate source. The experimental diets, 50% squid meal (SM50), 50% squid meal and 50% macroalgae (SM50+MA50), and 100% squid meal and 50% macroalgae (SM100+MA50) were substituted with the same respective amounts of soybean meal. The fifth experimental diet consisted of the control diet plus 1% diatom powder (DP). We prepared two domestic (Domestic A and B) and two imported (China and Japan) abalone feeds. Finally, we prepared Undaria and sea tangle. We found that the weight gain of abalone fed the Con, DP, and China and Japan diets was significantly greater than that of abalone fed Undaria and sea tangle. We conclude that the substituting squid meal and macroalgae with soybean meal in abalone feed has limited benefits, but supplementing diets with 1% diatom powder is effective in improving weight gain.

Soybean meal (SBM) is a major protein source in poultry feeds and one of the best quality ingredients because of the relatively high protein content, good amino acid profile and bioavailability. But soybean meal quality is largely dependent on the processing technology and origins. In this experiment, effects of three different soybean meals were evaluated in layer (experiment 1) and broiler (experiment 2). Soybean meal sources used in the experiments were the US-originated dehulled soybean meal (USDHSBM), India-originated non-dehulled soybean meal (India SBM) and Brazil-originated non-dehulled soybean meal (Brazil SBM). Experiment 1 was conducted during growing and laying periods and evaluated the interactive effects of soybean meal sources according to feeding periods on growth performance and egg quality. Experiment 2 was conducted during growing period (day 1-35) and finishing period (day 35-42). The growth performance was measured for the same periods and any possible interaction between soybean meal origins and crude protein levels was also studied. In experiment 1, chicks fed India SBM utilized feed more efficiently (p<0.05) than those fed Brazil SBM from day 29 to day 42. The body weights of layers during the laying period had no relation to egg production. But egg weights were significantly heavier in all the USDHSBM fed groups than other groups (p<0.001) and depended on feed protein source during growing period (p<0.001). The average egg weight of the USDHSBM fed group scored the highest value (65.4 g), followed by the Brazil SBM fed group (62.1 g) and India SBM fed group (62.1 g). There was an effect of interaction between origins of soybean meal fed group in growing and laying period on eggshell color (p<0.01). Eggshell was significantly stronger in the USDHSBM fed (for growing period) groups than other groups (p<0.05) on $31^{st}$ week. Haugh's unit (HU), albumin index and yolk index of the USDHSBM fed group in growing stage were significantly superior (p<0.001) to other groups. In experiment 2, for the 7-week, chicks on the India SBM group gained less (p<0.001) weight than other groups. While daily gain of India SBM chicks was not affected by dietary crude protein level, those of the USDHSBM and Brazil SBM chicks were linearly increased as dietary crude protein level increased from 18% to 20%. The gain per feed ratio of the USDHSBM group was the highest (0.585), followed by the Brazil SBM group (0.568) and India SBM group (0.550) (p<0.01). Therefore, in this experiment, the use of USDHSBM with excellent protein quality and amino acid digestibility could be of advantage to the economic production of layer and broiler.

This study was carried out to evaluate the utilization of fermented skipjack tuna viscera (FSTV) in the diet for juvenile abalone Haliotis discus hannai. Lactobacillus bulgaricus was used for fermentation of skipjack tuna viscera. Eight isonitrogenous (about 30% crude protein) diets were formulated to include different levels (0%, 10%, 20% and 30%) of FSTV as a replacer of either dietary fish meal or soybean meal. Three replicate groups of abalone were fed the experimental diets containing different levels of FSTV for 7 weeks. The inclusion of FSTV up to 30% in fish meal-based diet had no significant effect on survival, body weight, shell growth, and proximate composition of abalone (P>0.05). Weight gain of abalone fed the diet substituting 10% FSTV for soybean meal was not significantly different to that of abalone fed the control diet, however this value decreased in abalone fed the 20% and 30% FSTV (P<0.05).The contents of crude protein and lipid of soft body in abalone fed soybean meal-based diets were significantly affected by dietary FSTV level (P<0.05). The results of this study indicate that FSTV can be used as a partial substitute protein source for fish meal or soybean meal in the formulated diet for juvenile abalone.

A nutrition study on weaned pigs using fermented soybean meal was done to determine the effect on growth performance, nutrients digestibility, blood profile and fecal microflora. A total of 100 weaning pigs with an initial average body weight (BW) of 8.27 ± 1.10 kg were randomly allotted into 1 of 2 dietary treatments in a 6-week feeding trial. There were 10 replicate pens in each treatment with 5 pigs per pen. The dietary treatments included: 1) control: Basal diet (CON); 2) fermented soybean meal (FSBM): Basal diet supplemented with 5% fermented soybean meal. The average daily feed intake (ADFI) was significantly improved (p < 0.05) with the dietary supplementation of the FSBM compared with the control meal during phase 2. The dietary supplementation with 5% FSBM had a significant effect (p < 0.05) on gain to feed ratio (G : F) during the overall experiment period. Collectively, the results of this study indicate that dietary supplementation of 5% fermented soybean meal improved the body weight and average daily gain (ADG), ADFI, and feed efficiency of the weaning pigs; however, there were no supplementation effects on total tract digestibility of dry matter (DM), nitrogen, energy, blood profile and fecal microflora.

The influence of treated, extruded, partially expelled soybean meals as undegradable protein and bypass fat sources on lactation performance and ruminal fermentation of dairy cows was studied. Experiment 1: nine cows were used in a replicated 3${\times}$3 Latin square design with each period being 3 wk in duration. Cows were fed 440 g/kg forage and 560 g/kg grain diet with one of three extruded soybean meals fed at 110 g/kg of the diet. The 3 soybean meals were 1) twice-extruded soybean meal (ESM; as a control); 2) lignosulfonate-treated, twice-extruded soybean meal (LSM); and 3) calcium oxide plus lignosulfonate-treated, twice extruded soybean meal (CLSM). Experiment 2: 3 ruminally cannulated cows were used in a 3${\times}$3 Latin square to study the treatment influence on ruminal fermentation characteristics. Feeding treated soybean meal to cows in LSM and CLSM treatments did not improve feed intake, milk yield, or milk composition except that cows fed the LSM and CLSM treatments produced less milk protein compared with the ESM treatment. The proportion of $C_{18:2}$ was greater in milk fat of cows fed CLSM compared with that of cows fed the ESM or LSM treatments. Ruminal pH, ammonia, and total volatile fatty acids were not affected by treatment. An increased proportion of $C_{18:2}$ in milk fat suggests that there is a potential use of calcium salts of fatty acids in protecting the lipid portion of extruded soybean meal and further research is needed to explore this potential with full-fat extruded soybeans not with extruded and partially oil expelled soybeans.

The purpose of this study was to evaluate the effect of protected fat and heat-extruded soybean meal on the lactation performance of Holstein cows. Twenty-four cows, consisting of 20 lactating cows and 4 rumen-fistulated dry cows, were randomly allocated into four groups with 5 lactating cows and 1 fistulated cow in each group. A replicated 4${\times}$4 Latin square design with four 21 day periods, including 14 days of adaptation and 7 collection days within each period was employed. The experiment was a 2${\times}$2 arrangement, with or without heat-extruded soybean meal and protected fat inclusion. The dietary treatments consisted of supplements of (a) soybean meal (the control), (b) heat-extruded soybean meal, (c) protected fat, and (d) heat-extruded soybean meal and protected fat. The results showed that there were no significant differences in feed intake, milk yield, milk protein content, milk lactose content and body weight change between the dietary treatments. However, cows supplemented with protected fat showed a significantly increased (p<0.05) milk fat yield, 3.5% FCM and total solid yield. The increase in undegradable intake protein (UIP) via heat extruded soybean meal supplement significantly decreased the urea nitrogen concentration in the blood (p<0.05). Dietary fat inclusion significantly increased the blood cholesterol concentration (p<0.01) and decreased the ruminal pH value (p<0.01). Increased dietary UIP significantly decreased the ammonia nitrogen concentration in the rumen (p<0.01), but did not significantly influence the pH and VFA molar percentage in the rumen. It appears that dietary protected fat inclusion could improve milk fat and solid content. Increased dietary undegradable intake protein through heat extruded soybean meal did not improve milk yield. But it could alleviate the adverse effect of decreased milk protein due to dietary fat supplementation. Increased UIP could also decrease the ammonia nitrogen concentration in the rumen and plasma urea nitrogen concentration in the blood.
