This study investigated the awareness and consumption behavior of 118 vegetarians and omnivores toward plant-based dairy alternatives. The preference and choice attribute questionnaires were compared. Significant differences were obtained between the two groups when considering the purchase experience, preference, and selection attributes of plant-based dairy alternatives. Vegetarians had more experience purchasing plant-based dairy alternative products. In both groups, environmental and animal protection were the major factors that influenced the highest response rate for purchasing plantbased dairy alternatives. The preference score of vegetarians for plant-based dairy alternative products was high, indicating that vegetarianism had a significant effect on their preference for plant-based dairy alternative products. Analysis of selection attributes revealed that price, product weight, appearance, and manufacturer were considered important by vegetarians, whereas nutritional components and labeling, manufacturing environment, composition of ingredients, and taste and texture were considered more important by the omnivores. Results of this study can be used as basic data for the future development of the fast-growing industry producing plant-based dairy alternative products.

본 연구는 Holstein 거세 비육우의 성장 단계에 따른 채식 및 반추행동에 미치는 영향을 규명하기 위하여 실시하였다. 실험에 사용한 공시 Holstein 거세우는 육성 단계(T1), 비육전기 단계(T2) 그리고 비육 후기 단계(T3)을 각각 3두씩, 총 9두를 3처리 3반복으로 배치하였다. 사료급여는 농후사료 체중의 1.62%, 조사료는 자유 채식시킨 후 육안으로 48시간 채식 행동관찰을 실시하였다. 체중대비 건물섭취량은 T1구(2.21%) 가장 높게 T3구 (1.39%)가 가장 낮게 나타났다. 채식시간은 T1, 반추시간은 T2 그리고 휴식시간은 T3 구에서 높게 나타났다(p<0.05, 0.01). 저작 시간은 T1 및 T2구에 비하여 T3구가 현저히 떨어지는 것으로 나타났다(p<0.01). 식괴수와 총 저작수는 다른 처리구에 비하여 T2구가 유의적으로 높게 나타났다(p<0.01). 그러나 식괴 당 저작수 및 분 당 식괴수는 T1구가 높게 나타났지만 상호 처리간 유의적인 수준은 나타나지 않았다. 음수 회수 및 배분 회수는 처리 구들 간에 유의적인 차이가 없었다. 그러나 배뇨 회수는 어린 단 계인 T1 구에서 유의적으로 높게 나타났다(p<0.01). 음수 시간, 배분시간, 배뇨시간은 T1 구에서 높게 나타났지만, 개체 차이가 심하여 유의적인 차이는 보이지 않았다. 이상의 결과를 종합하면 비육후기 단계(T3)는 육성(T1) 및 비육전기(T2)비하여 체중대비 채식량이 낮음에 따라 채식시간 반추시간은 줄어들고 휴식시간은 증가하는 것으로 나타났다. 또한 T3구는 총 식괴수 및 총 저작수도 떨어지는 것으로 나타났다.

The objective of this study was to determine the effect of different pregnancy stages on the eating and ruminating behavior of Hanwoo heifers (Bos taurus coreanae). A total of twelve Hanwoo heifers were divided into four groups depending on pregnancy stage: C: before pregnancy, 9 months old, T1: 3 months pregnant, 16 months old, T2: 6 months pregnant, 19 months old, T3: 9 months pregnant, 22 months old (3 replicates per group). Concentrate of 1% of the body weight was fed to them. Roughage was provided at ad libitum to all treatments. Our results revealed that the intake of roughage was the highest in the T3 group (at 3.68 kg) and the lowest in the C group (at 1.02 kg, p<0.05). Total intake in the order from high to low was: T3 > T2 > T1 > C (p<0.05). The rate of dry matter intake compared to body weight (DMI/BW, %) from high to low order was: T3 > T2 > T1 > C (p<0.05). Eating time, ruminating time, and chewing time were the highest in T3 group (p<0.05). Resting time was the highest in C group (p<0.05). The number of bolus and the number of total chews were significantly higher in T3 compared to those in other groups. However, ruminating time per bolus was not significantly difference among groups. The number of chews per bolus from high to low order was: C > T1 > T3 > T2 (p<0.05). The number of bolus per minute was not significantly different among groups. The number of drinking and the number of defecating were significantly higher in C and T1, respectively (p<0.05). However, the number of urinating had no effect according to pregnancy stage. Eating rate and chewing efficiency were significantly higher (p<0.05) in accordance with pregnancy stage (T3 > T2 > T1 > C). Ruminating efficiency was significantly (p<0.05) higher T1 than that in other groups.

Increasing numbers of Korean adults, especially women, are adopting vegetarian diets for various reasons. In this study, the characteristics of vegetarianism among females residing in Seoul were examined. In addition, the dietary habits and eating behaviors between vegetarians and non-vegetarians were investigated. A total of 148 females (73 vegetarians, 75 non-vegetarians) were recruited and questionnaires regarding their demographic characteristics and eating habits were completed. The eating behavior and daily intake of food groups was assessed using the three factor eating questionnaire-R18 (TFEQ-R18) and food frequency questionnaire, respectively. The ages, BMI, education, and religious affiliation were not significantly different between the two groups. More than 30% of vegetarians had followed a vegetarian diet for longer than 24 months. The most common motivations for vegetarianism in study participants were ‘health or weight control’ (46.6%) followed by ‘environmental concerns or animal welfare’ (24.7%). Vegetarians had a lower intake of cereals, Kimchi, and soda, but a higher intake of potatoes and sweet potatoes, vegetables, mushrooms, seaweed, and fruits compared to non-vegetarians. Significant differences in eating behavior scores were also found between the two groups; in particular, vegetarians reported higher levels of restrained eating and emotional eating than non-vegetarians. Scores of uncontrolled eating, however, were not significantly different between the two groups. In conclusion, these results suggest that while vegetarianism is associated with healthy dietary habits, it is associated with restrained eating behaviors which may increase the risk of eating disorders in women.
