  • This trial was to compare the digestive function of laboratory animals, which included omnivores (rats) and herbivores (rabbits, guinea pigs and hamsters). Ten weanling rats, rabbits, guinea pigs and hamster were randomly allocated in individual metabolic cages for a performance and a digestibility trial. Results showed that guinea pigs were significantly best in digestion of dietary crude protein and fiber. Rabbits, however, had the poorest nutrient digestion among the herbivores. Crude fiber digested significantly less by rats than by the herbivores (p<0.05). The digesta retention in the GI tract was longest in rabbits followed by guinea pigs, rats and hamsters. The relative length of the large intestine was significantly shorter in rats as compared to guinea pigs or hamsters. Both the weight and length ratio of the caecum or colon-rectum to the large intestine reflected the major site for fermentation that was the caecum in rabbits and the colon-rectum in guinea pigs. 10% of crude fiber diet did not result in damaged mucosa in any of the experimental animals in this trial.

  • This experiment was conducted to compare the productivity of five silage corn varieties. Corn varieties were Pioneer 3144(P 3144), 3160(P 3160), 3282(P 3282), 3352(P 3352) and Suweon 19(S 19) and were seeded on May 2 and harvested on August 15. Ratios of stalk, leaf and ear, chemical composition and yields of nutrients were investigated in respective corn part. Experimental design was accepted by Latin square arrangement with five replicates and each plot had twenty two plants. The results obtained were as follows: 1. Crude portein, crude ash and nitrogen free extract(NFE) contents of whole plant ranged from 6.32 to 7.18%, 5.16 to 7.43% and 52.62 to 57.90%, respectively, and there were no significant(P>.Ol) differences between varieties. Crude protein and NFE content were the highest in ear between corn parts. 2. Crude fiber conent of whole plant ranged from 18.98 % to 24.01 %, and was the highest in suweon 19 and the lowest in P 3352(P<.01). Crude fiber content was the highest in stem and the lowest in ear, However, crude fat content(2.03-3.66 %) vice versa. 3. Yields of organic matter, crude protein, crude fat, NFE and TDN per 10a were the greatest(P< .01) in P 3282, however crude fiber yield was the highest(P<.Ol) in P 3352. 4. Ratios of different part to total dry matter yield ranged from 12.7 %(P 3352) to 17.8 %(P 3160) for leaf, 44.5(P 3352) to 66.9 %(P 3160) for stem and husks, and 16.9 %(P 3282) to 42.8 %(P 3352) for ear, and there were significant differences between corn varieties(P<.Ol). Consequently, P 3352 has the greatest nutrient yields, particularly by ear, and P 3282 has a great nutrient yield by stem. This result suggested that could be appear a better character of silage corn by hybridization of this two corn varieties.

  • An experiment was carried out to determine effect of cultivar, drying agent concentration and preservative on the moisture content, temperature and quality changes of fall harvested oat(Avena sativa L.) hay during field curing and storage. The main plots consisted of the cultivar such as 'Foothill' and 'Swan', the subplots consisted of drying agent concentration such as 7Skg/ha(C1), lOSkglha(C2) and control(C0) and the sub-subplots consisted of preservative such as buffered acid(BA), lactic bacteria inoculant(LB) and control(C0). Moisture contents of 'Foothill' and 'Swan' oat cultivar at harvest were 635.5 and 385.4%DW(Dry weight), respectively, but the final moisture contents of the oat cultivars were 117 and 86%DW. The moisture content of cut oat was not affeded by drying agent concentration. Core temperature of baled 'Swan' oat hay was a little higher than that of 'Foothill' and no consistent preservative effect was found. Total nitrogen content of 'Swan' oat hay was 3.08% and that of 'Foothill' oat hay was 3.45%(P<0.05). Drying agent treatment increased total nitrogen content of 'Swan'(P <0.05), but preservative had no effect. Crude fiber content of oat cultivar was increased as the curing progressed(P<0.05) and the difference of crude fiber content of oat cultivar was maintained through the whole curing period. Effect of drying agent concentration on crude fiber content was not found after preservation. Crude fiber content of 'Swan' oat hay was higher than that of 'Foothill' by 1.O% in ADF and 3.1 % in NDF(P<0.05). No preservative effect was found in crude fiber content. According to RFV of oat cultivar at harvest, forage quality of 'Foothill' and 'Swan' was Prime and Grade 1, respectively, but that of both cultivm was above Grade 2 at the final curing day. RFV of the stored 'Foothill' and 'Swan' oat hay was 122 and 114(P<0.05), respectively, and the quality of oat hay was classified as Grade 1 and 2, respectively, according to the forage quality standard assigned by AFGC.

  • This study was conducted to determine changes in th contents and composition of dietary fiber during the growth of soybean sprout. Soybean was soaked in water at $25^{\circ}C$ for 2hrs and cultivated at 2$0^{\circ}C$ for 7 days under dark condition. The soybean sprouts were divided into cotyledon and axis and sampled every 24hrs. The analysis methodlogies used were Van Soest's NDF, AOAC's ADF and lignin and Prosky's IDF, SDF, TDF. The weight of 100 sprouts increased gradually from 20.26g to 90.12g during the growth periods. The weight increased to 344.9% of the original weight. The germination rate was 100% after soaking at $25^{\circ}C$ for 2hrs. Root length increased gradualy from 0.6cm at 1st day to 17.2cm at 7th day. The crude ash and crude fat contents showed no significant change in the cotyledon and axis. The crude protein contents increased in the cotyledon and axis, whereas the total carbohydrate content didn't have general tendency. The insoluble dietary fiber(IDF), soluble dietary fiber(SDF) and total dietary fiber(TDF) contents of cotyledon were no significantly different from 20.01%, 1.45%, 21.46% at 1st day to 22.75%, 2.07%, 24.82% at 7th day on dry basis. In axis those contents increased from 23.19%, 1.97%, 25.16% at 1st day to 32.78%, 3.02%, 35.80% at 7th day, respectively. The neutral detergent fiber(NDF) contents of cotyledon and axis increased from 4.35% to 6.39% and from 6.44% to 26.60% respectively on dry basis. The acid detergent fiber (ADF) contents of cotyledon and axis increased from 2.84% to 4.91% and from 2.5% to 4.7%, but there were no significantly different in the hemicellulose and lignin contents on dry basis. The hemicellulose and lignin contents of axis increased with culture periods from 1.70% to 4.41% and from 0.20% to 2.11%, respectively. The cellulose contents increased from 4.54% to 20.35% on dry basis.

  • This research was conducted to examine the usability of Dangui (Angelica gigas Nakai, Root) and Seungumcho (Angelica gigas Nakai, Leaf) as functional food in aspects of their functional components and nitrite scavenging ability. Analysis of proximate composition showed that Dangui contains more moisture, crude lipid and crude protein than Seungumcho. On the other hand, Seungumcho contains more than twice mont of crude ash and crude fiber than Dangui. Dangui showed higher contents in phosphorus, iron, magnesium, and Seungumcho showed higher contents in copper, calcium, sodium, potassium compare to each other. Substances such as calcium, magnesium and iron that showed high contents in Dangui and Seungumcho are the most important inorganic substances. Total dietary fiber(TDF) of Dangui, sum of IDF and SDF, was 24.2%, and Seungumcho showed 28.18%. vitamin C contents of a 29.690.33 mg/100g appeared only in Seunggumcho. Total phenol contents of Dangui was 0.100${\pm}$002% and that of Seungumcho 0.0900${\pm}$008%. Nnitrite Scavenging ability of both water soluble and methanol soluble extracts were more than 90% at pH 1.2, and it decreased as pH level adjusted to pH 4.2, pH and 6.0.

  • The dietary fiber and crude fiber contents of different thallus regions (blade, stipe, and holdfast) in three brown algae (Laminaria japonica, Ecklonia stolonifera, and E. cava) were detennined at different ages, and then compared with one another. On a dry matter basis, the soluble dietary fiber (SDF) content was highest ($10.8{\pm}0.5%$) in the holdfast of 2-year old L. japonica, and the insoluble dietary fiber (IDF), total dietary fiber (TDF), and crude fiber (CF) contents were highest in the holdfast of 2-year old E. cava at $44.5{\pm}0.7%$, $50.2{\pm}0.5%$, $6.8{\pm}0.7%$, respectively. The IDF, TDF, and CF contents of these three species were measured in the following order: holdfast > stipe > blade, and the SDF contents of L. japonica exhibited the reverse of this trend. The TDF/CF ratio of 1-year old L. japonica, E. stolonifera, and E. cava was greater than was observed in the corresponding 2-year old samples. This is, to the best of our knowledge, the first report demonstrating that the holdfasts of L. japonica, E. stolonifera, and E. cava are rich in dietary fiber contents, especially IDF, TDF, and CF.
