Dried Jiwhang (Rehmannia Glutinosa, Liboschitz ex Fischer & Meyer) supplemented with 1%, 3% or 5% in ration was fed to 4 Berkshire pigs respectively and the other 4 pigs were fed with basal radon. The results obtained were as follows: 1) There was significant difference (p$lt;,0.05) for body weight gain between treatments. Body weight gains of pigs on the ration supplemented with 5% of Jiwhang were more than those of the other pigs. 2) Feed efficiency of the ration supplemented with 5% or Jiwhang was also highest. 3) The ration supplemented with 3% of Jiwhang was most palatable to pigs, and the ration with 5% of Jiwhang was more palatable to pigs than the basal ration or the ration supplemented with 1 % of Jiwhang. 4) Economical feeding value based on income of in basal ration was highest in 5% supplemented ration and that for 1% supplemented ration was slightly lower than that for control ration. 5) During the experimental period all of the pigs used were in good health and had no clinical symptoms. From the above results it is estimated that 5% of dried Jiwhang can be supplemented in the pig ration successfully.

郭鍾瀅,鄭鉉丞 진주산업대학교 1968 論文集 Vol.1 No.-

育成豚 飼料로서의 Russian Comfrey의 利用價値를 究明하고자 各各 4頭의 育成豚에 Russian Comfrey를 10%·20%· 30%씩 代置한 飼料와 基本飼料를 給與하여 比較飼養한 結果 다음과 같은 成績을 얻었다. 1)豚의 增體量은 10%代置區가 가장 優秀하였고, 30%代置區가 가장 不良하였으며, 20%代置區는 對照區와 有意差가 없었다. 2)飼料利用性도 對照區에 比하여, 10% 代置區는 優秀하였으며, 20%代置區는 비슷하고, 30%代置區는 不良하였다. 3)Russian Comfrey를 10%∼20% 程度로 代置飼養하면 飼料費가 節約되었으며, 30%代置는 不利하였다. 4)Russian Comfrey에 對한 豚의 嗜好性은 比較的 良好하였으며, Russian Comfrey 30%까지 代置給與하여도 健康上 異常은 별로 없었다. 以上의 結果로 보아 Russian Comfrey를 養豚飼料로 10%∼20% 程度 代置함으로써 有利한 經營을 꾀할 수 있다고 생각된다. The experiment was conducted to determine the feeding value of Russian Comfrey (Symphytum peregreoium) for pigs. Sixteen berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) such as 0%, 10%, 20%, and 30% (on air-dried basis) in pig ration. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows: 1)In weight gain, the pigs fed 10% R.C. ration showed more gain (P<0.05), but those fed 30% R.C. ration showed less gain (p<0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2)Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3)Feed cost for 1kg. weight gain was lowest in 10% R.C. ration and slightly higher in 30% R.C. ration than that in control ration. 4)From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.

This experiment was conducted to study the effects of level of dietary energy and protein on the growth rate, feed intake and feed conversion of chicken. One hundred and eight male baby chicken of Leghorn was used for 56 days. Starter ration (CP-17, 20,23%; M.E-1,030, 1,200, 1,370㎉/Lb) was fed to chicken for 4 weeks from 3 to 6-week age, and finisher ration (CP-14, 17, 20%; M.E-1,000, 1,215, 1,430㎉/Lb) was fed to chicken for 4 weeks from 7 to 10-weeks age. The results obtained from this study may be summarized as follows; 1) As the level of energy or protein increased in the ration, average daily gain were increased significantly. 2) Amount of feed consumed was significantly higher as the level of dietary protein. In feed conversion, chickens fed higher protein or higher energy were much superior to the chickens fed 10 wer protein or lower energy. 3) There was no influence of dietary energy or protein level on the chicken mortality. 4) Feed cost per kilogram of full body weight gain was increased greatly as the dietary energy level increased. 5) From the above mentioned results of this experiment it was thought that C_1 was profitable level in this study.

The experiment was conducted to determine the feeding value of Russian Comfrey (Symphtyum peregrenium) by growing pigs. Sixteen Berkshire gilts were alloted into 4 treatments according to the levels of Russian Comfrey (R.C.) in pig ration such as 0%, 10%, 20%, and 30% on air-dried basis. Body weight gain, feed efficiency, economical feeding value and palatability in each treatment were investigated. The experimental results obtained were as follows; 1) In weight gain the pigs fed 10% R.C. ration showed more gain (P$lt;0.05), but those fed 30% R.C. ration showed less gain (P$lt;0.05) than control group of pigs did. And the pigs fed 20% R.C. ration showed no more gain than the control pigs statistically. 2) Feed efficiency in 10% R.C. ration was also higher than that in any other rations. 3) Feed cost per ㎏. weight gain was lowest in 10% R.C. ration and slightly higher 30% R.C. ration than that in control ration. 4) From the feed intake it was considered that Russian Comfrey should be considerably palatable to pigs. And from the above results, it was estimated that Russian Comfrey could be supplemented by 20% in the pig ration successfully.

This experiment was conducted to determine the effect of Jiwhang`s leaf on weanling rabbits. Heaf of Jiwhang substitude with 10%(T_1), 20%(T_2), 30%(T_3) for grass in ration was fed with basal ration. The experimental results obtained were as follows; 1)In weight gain T_1 lot showed more gain (P.<0.05) than that in the control. T_2 lot, T_3 lot showed less gain than that in the control. 2)Feed efficiency of T_1 lot was also higher than that in any other lots. But T_2 lot, T_3 lot respectively showed less feed efficiency than that in the control. 3)T_1 lot was most palatable to rabbits. But T_2 lot, T_3 lot respectivly showed less palatability than that in the control. 4)All of the rabbits used in experimental period were in good health. T_1 lot was most vigorous. From the above mentioned results of this experiment it was estimated that the ration substituted with 10% of Jiwhang1s leaf was effective for rabbits.

本 試驗은 環境要因中 햇볕조사가 育雛에 미치는 영향을 究明하기 爲하여 試驗에 着手하였던 바 다음과 같은 결과를 얻었다. 1.增體率에 있어서는 處理區間에 1% 水準의 高度의 有意性이 있었고 孵化 1週後에 放射한 T_1區가 C, T_2, T_3區보다 有意性이 높았다. 2.飼料의 要求率에 있어서 T_1區가 0.353으로서 C區(0.327), T_2區(0.309), T_3區(0.312)보다 높았다. 3.斃死率은 T_1區=0%, C區=5% T_2區=15% T_3區=10%였다. 以上의 結果로서 햇볕조사는 ??化後 1週부터 實施하는 것이 效果가 있음을 認定할 수 있다. This experiment was conducted to determine the effect of sunlight belonging to the environmental factor on chick brooding. the results obtained were as follows; 1.There were observed a significant difference (p<0.01)for body weight gain between treatments. T_1 lot which received sunlight after 1 weeks from hatching showed more body weight gain than that of C. lot, T_2 lot and T_3 lot. 2.In feed conversion T_1 lot with 0.353 was higher than C. lot (0.327), T_2 lot (0.309) and T_3. lot (0.312). 3.There was a mortality of 0% in T_1 lot, 5% C lot, 15% in T_2 lot and 10% in T_3 lot. From the above mentioned results of this experiment it is effective to expose the growing chick to sunlight after 1 weeks from hatching.
