Purpose: This study was undertaken to examine the perception of Korean consumers regarding soybean meat. Using the Dietary Identify Questionnaire (DIQ), the data obtained were analyzed to identify various factors related to a plant-based diet. Methods: A consumer survey was conducted from June 1^st to 30^th, 2021, targeting 260 Korean consumers over the age of 20 years. Subjects were asked to answer six questions related to the perception of soybean meat. Of the 52 items present in the DIQ, 33 items were verified and reconstructed. All data were analyzed using the SPSS statistics (ver.25). Results: The subjects were divided into two groups, 'passive consuming group' and 'active consuming group', based on their perception of soybean meat. Demographic analysis according to the perception of soybean meat showed significant differences in age, marital status, academic background, and family members. The DIQ was categorized into 7 types: prosocial motivation, out-group regard, centrality, public regard, personal motivation, strictness, and private regard. Comparing by perception about soybean meat, significant differences were obtained between both groups for 'prosocial motivation (p < 0.01)', 'centrality (p < 0.01)', 'private norm (p < 0.05)', and 'personal motivation (p < 0.001)'. The 'passive consuming group' showed relatively low scores in all 4 factors. Conclusion: In the future, the results of this study can be applied to define the meaning of vegan in Korea. We believe our results will provide basic marketing data for the plant-based meat market. This will help expand the soybean meat market for a sustainable life for consumers, which is based on various needs such as health and the environment.

It was conducted to find out that the influence of lipids on blood cholesterol level of chicks and ducks. In this experiments, a comparative study was carried out using chicks and ducks divided into four groups with various diet for the period of four weeks. The results were as follows: 1. The mean value of hematocrit was significantly lower for the chicks fed sesame oil and soybean oil than the chicks fed duck meat. The value of hematocrit was higher for the ducks fed sesame oil, soybean oil and duck meat than for the control group. 2. Blood glucose level was higher for the ducks group than the chicks group. It was lower blood glucose level for the chicks and ducks fed duck meat than any other groups. 3. Blood cholesterol level was lower for the chicks fed sesame oil, soybean oil, and duck meat than for those fed the basal diet(control group). In the ducks group, blood cholesterol level was high. But in the liver organ, it was lower blood cholesterol level for the chicks and ducks fed sesame oil, soybean oil and duck meat, respectively than for those fed the basal diet(control group). 4. Phospholipid of the chicks which were control groups was lower value than for those fed sesame oil and duck meat fed, the value of phospholipid was higher value.

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.

Natto is a Japanese traditional soybean product fermented by Bacillus natto. The effect of natto supplement on the production and qualities of chicken meat was studied since the effective use of various waste foods is required in Japan. Dried natto prepared by heating at $60^{\circ}C$ was added to a basic diet at an amount of below 2%. The supplementation of dried natto did not influence the weights of the carcass, breast and thigh meat, fillet or abdominal fat. Growth of the thighbone such as the length, thickness of cortex bone, and Ca/P ratio in bone ash were not altered by the addition of natto. However, the pH of male meat decreased following the supplementation of dried natto from days 28 to 80. The water-soluble protein content in male thigh meat increased in the group fed 2% natto from days 28 to 80. Free peptides increased in male thigh meat by feeding 2% natto from days 0 to 80. The supplementation of natto increased free glutamic acid in thigh meat regardless of sex. Moreover, the supplementation of natto specifically decreased meat cholesterol in female chickens though the effect was not shown in male chickens.

This study was conducted to evaluate the increase of DPPH radical scavenging activity of meat substitute by heating. The meat substitute showed higher DPPH radical scavenging activity than those of other foods rich in protein such as beef, pork, chicken, and soybean curd. The DPPH radical scavenging activity of meat substitute was dependent upon concentration, heating temperature and heating time of meat substitute. The DPPH radical scavenging activity of meat substitute was enhanced with increasing heating temperature and time. The increase of DPPH radical scavenging activity was only applied to meat substitute without showing any activation in other foods rich in protein such as beef, pork, chicken, and soybean curd.

Paddy rice is rarely used as a feed because of its high fiber content. In this study, two experiments were conducted to study the effects of supplementing an enzyme complex consisting of xylanase, beta-glucanase and cellulase, to paddy-based diets on the performance and nutrient digestibility in meat-type ducks. In the both experiments, meat-type ducks (Cherry Valley) were randomly assigned to four treatments. Treatment 1 was a basal diet of corn-soybean; treatment 2 was a basal diet of corn-paddy-soybean; treatment 3, had enzyme complex added to the corn-paddy-soybean basal diet at levels of 0.5 g/kg diet; and treatment 4, had enzyme complex added to the corn-paddy-soybean diet at levels of 1.0 g/kg diet. The results showed that the enzyme complex increased the ADG, and decreased the ADFI and F/G significantly (p<0.05) in the ducks, and the ADFI for the ducks fed the corn-paddy-soybean diet showed no difference compared to the ducks fed corn-soybean diets at all stages of the experiment (p<0.05). When corn was partially replaced by paddy, the digestibility of CP and NDF was decreased and increased, respectively (p<0.05), and the level of enzyme complex had a significant effect on both CP and NDF digestibility (p<0.05). As for the AME, addition of enzyme complex increased it significantly (p<0.05), but both diet types and levels of enzyme complex had no effect (p>0.05). The outcome of this research indicates that the application of enzyme complex made up of xylanase, beta-glucanase, and cellulase, in the corn-paddy-soybean diet, can improve performance and nutrition digestibility in meat-type ducks.

This study was conducted to examine the effect of salt concentration in soybean sauce (ganjang) on pre-rigor ground Hanwoo (Korean native cattle) muscle. Although adding soybean sauce reduced pH of pre-rigor Hanwoo muscle, it improved the water holding capacity (WHC), cooking loss, total protein solubility, myofibrillar fragmentation index (MFI), 2-thiobar-bituric acid (TBA) values, and textural properties by increasing salt concentration in the soybean sauce. In particular, adding soybean sauce inhibited lipid oxidation despite increasing salt concentration. An increased salt concentration in the soybean sauce in pre-rigor Hanwoo muscle tended to make the meat have lower lightness and higher redness and yellowness values. Although soybean sauce had a significantly lower pre-rigor salting effect than sodium chloride in terms of cooking loss and total protein solubility (p<0.05), soybean sauce improved myofibrillar fragmentation and lipid oxidation when compared with sodium chloride. Furthermore, no significant differences in textural properties were observed between adding soybean sauce and sodium chloride at the same salt concentrations. Therefore, soybean sauce can be a functional curing material for pre-rigor muscle.

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.

The response of broiler chicks to intubation of nutrients (starch, casein, soybean oil or their combinations) into the crop immediately after hatch was evaluated for performance, intestinal development, meat yield and immune competence up to 35 d of age. A control group with no access to feed and two test groups fed either inert material (sawdust) or starter diet for the initial 24 h after hatch were compared with nutrient intubated groups (n = 7). A total of 300 broiler chicks were equally distributed to 10 dietary groups with 6 replicates of 5 chicks each. After 24 h of hatch, all groups were fed ad libitum the starter (0-21 d) and finisher diets (22-35 d). Results indicated that post-hatch intubation of starch into the crop significantly (p${\leq}$0.05) improved body weight (at 14 and 35 d of age), readyto-cook meat yields, weights of breast muscle and small intestine segments, cell-mediated immune response, ND titers and weight of bursa compared to chicks starved or fed sawdust during the initial 24 h after hatch. However, chicks with access to feed immediately after hatch or intubation of starch, soybean oil, starch+casein, starch+soybean oil or starch+casein+soybean oil exhibited similar positive effects. Intubation of casein either alone or in combination with soybean oil was superior to the starved or sawdust fed groups, but inferior to other groups for all the parameters studied. It was concluded from the study that intubation of starch individually or in combination with casein and/or soybean oil effectively circumvented the negative effects of post-hatch starvation for 24 h. Among the nutrients intubated, carbohydrate (starch) was better utilized by the chicks than protein (casein) or fat during the initial post-hatch period.

Objective: This study was conducted to compare growth performance, nutrient digestibility and meat quality of broilers fed a genetically modified organism (GMO) diet or a non-GMO diet. Methods: A total of 840 broilers with an initial body weight of 43.03 g per chick were randomly allocated into 1 of the following 2 dietary treatments lasted for 32 days (15 broilers per pen with 28 replicates per treatment): i) Trt 1, GMO maize-soybean meal based diet; ii) Trt 2, non-GMO maize soybean meal based diet. Both diets were maize-soybean meal diets. The GMO qualitative analysis, proximate analysis and amino acid analysis of the feed ingredient samples were carried out. Diets were formulated based on a nutrient matrix derived from analysis results. Growth performance was measured on day 0, 7, 17, and 32. And all other response criteria were measured on day 32. Results: The analysis results showed that the total Lys, Met, Thr of non-GMO grains were lower than that of GMO grains, the protein content of GMO soybean meal was higher than that of non-GMO soybean meal. Feed intake and feed conversion rate (FCR) were greater (p<0.05) in broilers provided with non-GMO diet than that of the GMO group from d 17 to 32. A decrease in FCR was observed in birds fed the GMO diet through the entire experiment (p<0.05). No significant impacts on blood profile, meat quality and nutrient digestibility were found in response to dietary treatments throughout the experimental period (p>0.05). Conclusion: These results indicated that non-GMO diet showed a negative effect on growth performance but nutrient digestibility, blood profile, carcass weight and meat quality were not affected by non-GMO diets.
