This study was carried out to investigate the effects of a different growing stage on the eating and ruminating behavior of Holstein steer (Bos taurus). A total of nine Holstein steers were divided into three growing stage groups (T1: growth stage, 8 months old, T2: Early fattening stage, 15 months old, T3: late fattening stage, 24 months old) with 3 replicates. In the feeding method, concentrate was offered at 1.62% of the body weight per treatment, respectively. And the forage was fed ad libitum for all treatment. The results of behaviors are summarized as follows: The rate of dry matter intake compared to body weight (DMI/BW, %) was high in the order of T1(2.21%) > T2(2.09%) > T3(1.39%). Eating time, ruminating time and resting time were significantly higher in T1, T2 and T3, respectively(p<0.05, 0.01). Chewing time was significantly lower in T3 than in T1 and T2(p<0.01). The number of bolus and the number of total chews were significantly higher in T2 than those of the other treatments(p<0.01). However ruminating time per bolus and the number of bolus per minute were not significantly different among the treatments. The numbers of drinking and defecating were not significantly different among the treatments. The number of urinating was significantly higher T1 than those of the other treatments(p<0.01). Time of drinking, defecating and urinating was not significantly difference among the treatments.

Normal healthy non vegetarian and lact$\infty$,vo­v vegetarian women were studied after they con­S sumed carrot juices as supplements. Daily sup­p plementation resulted in significant increase in serum levels of $\alpha$-, $\beta$-carotene and total carote­n noid in nonvegetarians and $\alpha$-and $\beta$-carotene in lactoovovegetarians. Reflection in serum and $\beta$-carotene was higher in nonvegetarians m than lactoovovegetarians. However, serum caro­t tene values were not significantly different between group after continous supplementation of reducing amounts of carotenes. Serm retionol levels were not changed throughout the study period and were not significantly different bet­w ween nonvegetarians and lactooovegetarians. The results suggest that serm total carotenoid cannot bean indicator of individual carotene such as $\alpha$-or $\beta$-carotene in serum and serum carotene levels are closely related to dietary carotene intake both in nonvegetartins and lac­t toovovegetanans

전 세계적으로 건강, 환경보호, 윤리적 소비를 추구하는 소비자들이 증가하면서 다양한 분야에서 동물성 제품을 섭취하거나 소비하지 않는 생활방식인 비거니즘(Veganism)을 지향하는 사람들이 증가하고 있다. 한국 또한 매년 채식에 대한 관심이 높아지고 있지만 외국에 비해 채식하기에 좋은 환경은 구축되어 있지 않으며 가공식품을 구매할 경우 성분 표를 일일이 확인해야 하는 어려움이 있다. 본 연구에서는 사용자가 섭취하고자 하는 가공식품의 성분을 분석하여 본인의 채식주의자 단계에 적합한 제품인지 쉽게 판별할 수 있는 모바일 앱을 제안한다.

최근 동물성 제품을 섭취하거나 소비하지 않는 비거니즘 생활방식을 지향하는 사람들이 증가하고 있다. 그러나 채식 인구의 증가에 수반되어야 하는 채식하기 좋은 환경에 대한 구축은 아직도 미흡한 실정이다. 본 연구에서는 채식주의자들을 위해 가공식품 성분 표를 분석하여 채식주의자 단계에 맞는 대체식품을 추천해 주는 시스템을 제안한다. 제안 시스템은 먼저, 가공식품의 원재료들이 표기되어 있는 성분 표를 분석하여 사용자의 채식주의자 단계에 적합한지를 확인한다. 확인 결과 적합하지 않다면, 한국식품안전관리인증원의 공개 API를 이용하여 해당 가공식품과 제품 유형이 같은 식품을 검색하고 그 결과로부터 사용자의 채식주의자 단계에 적합한 원재료들이 포함되어 있는 식품을 추천해준다.

This experiment was conducted to examine possibility and suitability of forest by-product as a roughage source of deer. As a experimental diet, forest by-product silage(FPS) and commercial mixed ration(CMR) were prepared to compare dry matter intake, digestibility, nitrogen balance and feeding behavior in feeding trials with spotted deer. The digestibility of dry matter was higher(P<0.05) in CMR than in FPS. The digestibility of crude protein was higher in CMR than in FPS and there was significant difference(P＜0.05). CMR had more digestibility of crude fiber than FBS but the difference was not significant. Dry matter intake were similar in both diets. Digestible dry matter intake was higher in CMR than FPS, however, there was no significant difference between experimental diets. Nitrogen intake, urinary and digestible nitrogen were significantly higher(P<0.05) in CMR than FPS. The efficiency of nitorgen utilization was higher for FPS than for CMR. Feeding behavior were similar in FPS and CMR. Consequently. It would be expected that FPS that composed with various feed sources can be used as a good roughage source of deer. Because it has high digestibility, dry matter intake and internal availability of nitrogen.
