To test the availability of soybean meal as a protein source and to increase its effectiveness in the diets for the fingerlings of red seabream, some feeding trials were conducted. Two different types of diet, steam pellet and soft dry pellet, contained various levels of soybean meal, were used. The growth, feed efficiencies, and body compositions were examined after the feeding trials. Results of the experiments suggested that dietary protein level could be reduced from $52{\%}$ to $47{\%}$ by elevating dietary energy level from $13{\%}$ to $21{\%}$ with lipid. The best results of growth and feed efficiencies were achieved by the diet that containing $47{\%}$ of crude protein and $20{\%}$ of crude lipids. The growths and feed efficiencies showed no difference when $20{\%}$ of fish meal in the experimental diet were substituted by soybean meal. Therefore, $20{\%}$ of fish meal could be substituted by soybean meal without reducing growth rates or feed efficiencies of fingerling red sea bream.

The purpose of this study was to evaluate effects of replacing soybean meal with perilla seed meal (PSM) on growth performance, proximate composition of meat, meat quality, and fatty acids composition of meat in broilers. A total of 60 one-day-old chicks of ROSS 308 (initial body weight of 44.8 ± 0.4 g) were randomly allotted to four treatment groups (15 replicate cages with 1 broilers per cage) in a period of 5 weeks. Dietary treatments included control (CON) basal diet (corn-soybean meal-based diets) and test diets in which PSM was included at 0.5% (T1), 1% (T2), or 2% (T3) to gradually replace soybean meal. At the end of experiment, all broilers were slaughtered for collecting breast and thigh meat. At 5 weeks, T2 and T3 treatment groups had higher (p < 0.05) body weights than CON and T1 treatment groups. Weight gain was increased (p < 0.05) in T2 and T3 treatment groups. Feed intake was decreased (p < 0.05) in T3 treatment group. Broilers in T2 treatment group had lower (p < 0.05) feed conversion ratio than those in other treatment groups. In proximate composition of breast meat, there was no significant (p > 0.05) difference in moisture and ash. Fat composition of breast meat was significantly (p < 0.05) increased in T2 and T3 treatment groups. Regarding meat quality, broilers fed T3 diet had higher (p < 0.05) water holding capacity than those fed other diets. Regarding fatty acids composition of thigh meat, broilers fed T3 diet had higher (p < 0.05) linolenic acid than those fed other diets. In conclusion, soybean meal replaced by 2% perilla seed meal in broiler diet can improve growth performance, meat quality, and fatty acids composition of thigh meat in broilers. Perilla seed meal can be a lot of potential alternatives feedstuff for soybean meal in this study.

This experiment was conducted to evaluate the long term effects of dehulled soybean meal (DHSM) as fish meal (FM) replacer in the diet for olive flounder, Paralichthys olivaceus, for 42 wk at a commercial fish farm. The four experimental diets were MP (moist pellet based on raw fish), $DHSM_0$ (fish meal based dry pellet), $DHSM_{30}$ (30% fish meal was replaced by DHSM) and COMD (commercial dry pellet). Fish were fed one of the four diets containing 50% crude protein and 16.7 kJ available energy/kg diet for 42 wk. Fish averaging $3.20{\pm}0.04g$ ($mean{\pm}SD$) were initially distributed to each tank as a group of 6,000 fish reared in a flow-through system. At the end of the experiment, average body weight of fish was $315{\pm}9.3g$ ($mean{\pm}SD$) ). Weight gain (WG) and feed efficiency (FE) of fish fed MP, DHSM0 and DHSM30 showed no significant difference among the diet treatments. However, WG and FE of fish fed MP were significantly higher than those of fish fed COMD (p<0.05). Specific growth rate (SGR), protein efficiency ratio (PER) and survival of fish fed all diets were not significantly different among the dietary treatments. Therefore, these results indicate that DHSM could replace up to 30% white fish meal with amino acid supplementation in olive flounder diets for long-term feeding practice at the commercial farm.

This study was carried out to investigate the effects of dietary lipid sources and meal frequency on growing performance and lipid metabolism in Sprague-Dawley strain male rats. The experiment was conducted in 4$\times$2 factorial arrangement with 4 sources of dietary lipid(palm oil, beef tallow, soybean oil and hydrogenated soyben oil) and 2 meal frequencies(ad-libitum or meal feeding). During the 4-week feeding period the rats were fed either ad-libitum (AL) or a single daily 3-hour meal (09 : 02-12 : 00) during the dark period. In vitro cultures were carried out to study the cholesterol synthetic activity in hte liver prepared from rats used in feeding trials. And in vitro cultures were also carried out to study the lipogenic and lipolytic activity in the liver and adipose tissues prepared from rats used in feeding trials. Present data indicated that body weight gain, feed intake and FER of AS(ad-libitum+soybean oil)and AHS(ad-libitum+hydrogenated soybean oil) group were significantly(p<0.05) higher than those of the other groups. It was found that the feed intake of MF group was much less than that of AL group. Total body weight gained by MF group was only 60% of AL group. Growing performance was not affected by dietary lipid sources. The cholesterol synthetic activity in liver tissues culture was markedly(p<0.05) increased in MF diets, especially in soybean oil group. The lipogenic activity in liver tissues culture of MP(meal feeding+palm oil) and MHS(meal feeding+hydrogenated soybean oil)group was significantly (p<0.05) higher than that of AP(ad-libitum+palm oil) group and AHS(ad-libitum+hydrogenated soybean oil) group(p<0.05). Rats fed ad-libitum+beef tallow and fed meal feeding+beef tallow showed significantly(p<0.05) higher lipogenesis than the other groups. It was apparent that the lipogenic activity in liver tissues culture was not affected by dietary lipid sources and meal frequency. Lipolytic activity in liver tissue culture was significantly(p<0.001)different with meal frequency; MF group was higher than AL group, but was not greatly affected by dietary lipid sources. In the in vitro studies with adipose tissue, MF diets increased the lipogenic activity and inhibited the lipolytic activity in adipocytes. The lipogenic activity in adipocytes was significantly (p<0.001) different with dietary lipid sources and found to be beef tallow group was the higherst, but the sources of lipid in the diet did not exert any effect on the lipolytic acitivity.

The effect of duodenal infusion with feed oligo-peptide solution on portal absorption of amino acids was investigated in poultry under unanaesthetized conditions. Four peptide solutions were used in the experiment: enzymatic hydrolysates from fish meal, soybean meal, cottonseed meal and rapeseed meal proteins with average molecular weights less than 3,000 Da and 1,000 Da, respectively. Intestinal absorptions of these oligo-peptide solutions were compared by determining the concentration of free amino acid (FAA) in portal blood after the duodenal administrations of oligo-peptide solutions. Absorptive intensity and balance were used to estimate the intestinal absorption rate of amino acids. The absorptive intensities of amino acids were highest for the fish and soybean meal oligo-peptides. The ratios of amino acids absorbed in the portal blood from fish and soybean meal oligo-peptides were more similar to the composition of the infused amino acids than that observed from the cottonseed and rapeseed meal oligo-peptides. A positive correlation was found between absorption rate and proportion of PAA in the oligo-peptides. The higher absorption rate could be contributed to the higher proportion of peptide bound amino acids (PAA). The results suggest that fish and soybean meal protein are significantly more easily hydrolyzed into oligo-peptides (p<0.05) in the gastrointestinal tracts of poultry and as such can be utilized more effectively by body tissues.

In this research, the possibilities of using canola meal (CM) in place of soybean meal (SBM), and also the effects of multi-enzyme and phytase supplementation on the performance of quails were investigated. For this purpose, soybean meal (44% CP), canola meal (37% CP), phytase (produced from Peniophora luci) and multi-enzyme ($\beta$-glucanases, pectinases, cellulases and hemicellulases) were used. CM was used supplying 0, 25 and 50% of CP from SBM and each of the phytase and multi-enzyme blends were added to the each level. This study was conducted with 675 day old quails (Coturnix coturnix Japonica) in 9 groups with 3 replicates including 25 birds (mixed sex) per replicate. Nine isocalaric and isonitrogenous diets were prepared. The effects of enzymes and CM levels were studied with a 3${\times}$3${\times}$3 factorial arrangement for three CM levels (0, 25 and 50%), three treatments (without enzyme, phytase enzyme and multi-enzyme) and three replicates. While the 25% CM level did not affect the liveweight gain 50% CM level decreased the liveweight gain (p<0.05). Multi-enzyme addition to the 50% CM group increased the liveweight gain compared to the other groups (p<0.05). CM levels and enzyme supplementation had no effect on feed consumption, feed conversion ratio, dressing percentage, viability, tibia ash content, Ca and P contents of tibia ash, viscera weight, gizzard weight and length of growth period. While heart weight and liver weight were not affected by CM levels, but they were affected by enzyme supplementation. CM levels and enzyme supplementation did not affect final liveweight, feed consumption, feed conversion ratio, egg yield, egg weight, shell weight and shell index during laying period. The increase in the CM level lightened the colour of the yolk (p<0.05).

This study was conducted to determine the effects of the dietary microbial phytase (P) supplementation on growth performance and bioavailability of phosphorus in juvenile olive flounder, Paralichthys olivaceus and juvenile Korean rockfish, Sebastes schlegeli fed soybean meal-based diets. Nine experimental diets were formulated to be isonitrogenous and isocalolic to contain 50.0%crude protein (CP) and 16.7kJ, 48.6% crude protein (CP) and 16.0kJ available energy/g without the dietary phytase supplementation for olive flounder and Korean rockfish, respectively : 100% fish meal (FM); 70% FM ＋ 30% soybean meal (SM); 70% FM ＋ 30% SM ＋ Phytase(P) 1000U/kg diet; 70% FM ＋ 30% SM ＋ P 2000U/kg diet; 70% FM ＋ 30% SM with phytase-treated (Ptre) P 1000U/kg diet; 60% FM ＋ 40% SM; 60% FM ＋ 40% SM ＋ P 1000U/kg diet; 60% FM ＋ 40% SM ＋ P 2000U/kg diet; 60% PM ＋ 40% SM with Ptre P 1000U/kg diet. After two weeks of the conditioning period, triplicate groups of 25 fish initially averaging 6.15$\pm$0.04g, was randomly distributed into the aquarium for olive flounder, and 20 fish initially averaging 7.25$\pm$0.04g was randomly distributed into the aquarium for Korean rockfish. After 8 weeks feeding trials, there was no significant difference on weight gain fish fed between 100% FM and 70% FM＋30%SM with Ptre P 1000U in olive flounder and Korean rockfish. Apparent phosphorus digestibility fish fed phytase supplemental diets were significantly higher than those of fish fed phytase non-supplemental diets in olive flounder and Korean rockfish. Therefore, these results indicated that pre-treated soybean meal with phytase 1000U could replace fishmeal up to 30% for the maximum growth of juvenile olive flounder and Korean rockfish. Phytase supplementation could improve apparent digestibility of phosphorus in olive flounder and Korean rockfish fed soybean meal based diets.

One growth trial and one digestibility trial were conducted to evaluate the nutritional value of HP300, a commercially processed soybean meal product for weanling pigs. Dried whey, fish meal and/or full fat extruded soybeans (FFES) as well as portions of soybean meal (SBM) were replaced with HP300 in weanling pig diets. The objectives were to investigate the effects of HP300 on growth performance, digestibility, ileal amino acid digestibility and blood amino acid concentration in weanling pigs. One hundred and twenty crossbred $(Duroc{\times}Beijing\;Black{\times}Landrace)$ pigs weaned at 28 days of age were used in the growth trial. The pigs were randomly allocated to five treatments, with three pens per treatment and eight pigs per pen. The trial duration was 28 days. The control (CTRL) diet contained no HP300; in treatments 2, 3 and 4, dried whey and fish meal were replaced by 3.0%, 7.5% and 10.5% HP300; in treatment 5, full fat extruded soybeans were replaced by 10.5% HP300 plus soybean oil to attain the same metabolic energy content as FFES. Five T-cannulated barrows were used in a digestibility trial with a $5{\times}5$ Latin square design to determine nitrogen retention and amino acid ileal digestibility of HP300 used alone or mixed with other ingredients. The results indicated that replacement of dried whey, fish meal, full fat extruded soybeans and a part of the soybean meal with HP300 in piglet diets improved average daily gain and feed conversion ratio (p < 0.05). There was a trend toward improved DM, crude protein and amino acid ileal digestibilities and improved protein and amino acid ileal digestibilities and improved protein net availability with the use of HP300 in swine diets.

An 8 weeks feeding trial was carried out to evaluate the effects of dietary microbial phytase (P) supplementation on nutrient digestibility, and body composition in juvenile olive flounder Paralichthys olivaceus fed soybean meal-based diets. Seven experimental diets were formulated to be isonitrogenous and isocaloric to contain 50.0% crude protein (CP) and 16.7 kJ of available energy/g with or without dietary phytase supplementation. White fish meal (FM) provided 92.4% of the total protein in the basal diet ($S_0$), in the other 6 diets, 30% or 40% FM protein was replaced by soybean meal: 70% FM + 30% soybean meal ($S_{30}$); 70% FM + 30% SM + 1000 U phytase/kg diet ($S_{30}P_{1000}$); 70% FM + 30% SM + 2000 U phytase/kg diet ($S_{30}P_{2000}$); 60% FM + 40% SM ($S_{40}$); 60% FM + 40% SM + 1000 U phytase/kg diet ($S_{40}P_{1000}$); and 60% FM + 40% SM + 2000 U phytase/kg diet ($S_{40}P_{2000}$). After two weeks of the conditioning period, triplicate groups of 25 fish initially averaging $6.15{\pm}0.04g$ ($mean{\pm}S.D.$) were randomly distributed into the aquarium and were fed one of the experimental diets for 8 weeks. After feeding trial, supplementation of phytase significantly improved the apparent digestibility coefficients of phosphorus in flounder diets (P<0.05) containing 30% and 40% soybean meal regardless the levels. However, phytase had no significant influence on growth performance and whole body composition of fish. Based on the experimental results, we conclude that dietary supplementation of phytase could improve the apparent digestibility coefficient of phosphorus in olive flounder.

This study was carried out investigate the effect of replacing soybean meal with feather meal or Bacillus sp. inoculated feather meal in finisher pig diets on the performances, and amino acid composition and carcass characteristics of pork. One hundred fifty pigs were randomly allotted to five dietary treatments (① control, basal diet; ② BSM (bacillus sp. inoculated soybean meal) 10, 10% of soybean meal was replaced with bacillus sp. inoculated feather meal; ③ BSM 20, 20% of soybean meal was replaced with bacillus sp. inoculated feather meal; ④ CSM (conventional soybean meal) 10, 10% of soybean meal was replaced with conventional feather meal and ⑤ CSM 20, 20% of soybean meal was replaced with conventional feather meal) in a 70-days feeding trial. In overall period, body weight gain of BSM 20 (0.95kg) was higher (P<0.05) than those of CSM 10 (0.80kg) and CSM 20 (0.81kg), respectively. And feed conversion of BSM 20 (2.94) was lower (P<0.05) than that for other treatments (3.06-3.41). Carcass weight of BSM 10 (81.84kg) and BSM 20 (83.77kg) were greater (P<0.05) than those of CSM 10 (74.75kg) and CSM 20 (76.07kg), respectively. Proportion of grade A carcass in BSM 20 (35.03%) was higher compared to the control treatment (32.78%). CIE L* of meat color was lowest in the BSM 10 (45.56), and hightest (P<0.05) in the CSM 20 (59.96). In addition CIE a* of meat color of control (9.35) highest (P<0.05) than those of BSM 10 and BSM 20 were 7.56 and 7.42, respectively.
