  • 본 시험에서는 왕겨, 쌀겨, 비지, 잔반을 원료로 하여 각각 26, 26, 34, 14%를 혼합하여 발효시켜 농후사료와 급여비율을 달리하여 재래산양에게 급여하였다. 시험사료는 4종으로 각 사료별 발효사료:농후사료 배합비율은 A 80 : 20, B 70 : 30, C 50 : 40 및 D 50 : 50%로 하여 처리구별로 급여하였다. 발효사료를 이용한 재래산양의 사료 섭취량, 소화율 및 질소 축적율을 조사하였으며 또한 재래산양의 증체 시험을 45일간 실시하여 재래산양 사료로서의 농산부산물 발효사료 가치를 조사하였다. 1. 본 실험사료의 화학적 성분으로는 조단백질 함량이 A, B, C 및 D구에서 각각 13.73, 13.78, 14.45, 15,14%이었으며 조지방과 조섬유 함량은 A구에서 각각 8.66 및 27.82%로 전 처리구중 가장 높았다. 2. 처리수준별 건물사료 섭취량은 362.06∼329.12g/d로서 A구(발효사료 : 배합사료, 80 : 20)와 C구(발효사료 : 배합사료, 60 :40)에서 각각 362.06 및 358.49g/d로서 B구(329.12g/d)와 D구(349.72g/d)에 비하여 유의성이 인정되었다(P<0.05). 영양소별 섭취량으로 조단백질 및 조지방은 처리구간 차이가 없었으나(P>0.05), 조섬유 섭취량은 A구가 101.47g/d로 B, C 및 D구보다 현저히 높아 유의차를 보였고(P<0.05), 조회분 섭취량도 A구가 28.51g/d로 B, C 및 D구보다 현저히 높았다(P<0.05). 3. 처리구간 건물소화율은 68.81∼53.58%수준으로 발효사료가 60%함유된 사료를 급여한 C구에서 가장 높은 경향을 보였으며, 발효사료 함유율이 80%인 A구에서 가장 낮았다 (P<0.05), 조단백질 소화율도 A구에서 59.85%로 B, C 및 B구보다 현저히 낮아 유의차가 인정되었다(P<0.05). 그러나 조지방의 소화율은 처리간 큰 차이를 보이지 않았다. 조섬유 소화율은 A구와 C구에서 각각 56.82%와 58.54%를 나타내어 발효사료 함유량이 높아도 조섬유 소화율이 저하하지 않는 것을 알 수 있었다. 4. 질소 섭취량은 8.47∼7.22g/d로서 C구에서 8.47g/d로 가장 높았으나 질소 축적율은 D구에서 32.78%로 가장 높게 나타났다. D구는 배합사료 급여 비율이 50%로 처리구중 조단백질 함량이 제일 높았고 분 질소 배설량이 적어 질소 축적율이 향상되었다고 P<0.05) 사료된다. 뇨 질소 배설량은 3.43∼5.91g/d로 전 처리구간 비슷한 경향을 보였다. 5. 증체 시험 결과를 보면 사료 섭취량은 752.22∼788.20g으로 처리구간 비슷하였으나, 일당 증체량은 발효사료1배합사료 비율이 50 : 50%인 D구에서 88.89g/d으로 가장 높았고, A, B, C구는 체중이 감소하거나 증체가 거의 이루어지지 않았는데, 개체별로 일부 설사에 의한 체중감소 현상이 일어났기 때문으로 사료된다. 그러나 설사를 하지 않은 정상적인 것들만 비교하여 볼 때, 증체량은 배합사료 급여 비율이 높을수록 증가하는 경향을 뚜렷이 보여 주었다(C : 71.11, D : 88.89g/d). 6. 왕겨, 쌀겨, 비지, 남은 음식물 등을 이용한 발효사료를 배합사료와 함께 혼합 비율을 달리하여 재래산양에게 급여하였을 때, 사료 섭취량과 소화율은 발효사료 60%, 배합사료 40%를 급여하였을 때 가장 높게 나타나 농산 부산물을 발효시킴으로써 기호성 및 소화율이 향상될 수 있다는 점을 시사하였다. 그러나 발효사료는 배합사료만큼은 체내 이용성이 뛰어나지 못하여 배합사료 50%로 배합사료 혼합 비율을 높인 구보다는 증체량이 떨어졌고 질소 축적율도 낮게 나타났다. 결론적으로 재래산양에서 배합사료와 함께 급여하는 발효사료의 적정 급여 비율을 50∼60% 정도로 할 때 사료의 이용 효율이 양호할 것으로 사료되나 여름철과 같은 고온 시기에는 변질리 가능성이 있어 설사를 유발할 수 있으므로 이에 대한 추가 연구가 필요하다고 사료된다.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.
