河正基,李炳五,郭鍾瀅,安炳弘 慶尙大學校 1972 論文集 Vol.11 No.-

初生雛 育成飼料의 主飼料인 옥수수의 代置飼料로서 밀을 이용한 代置水準을 究明하고저 本 實驗을 實施하였던 바 그 結果는 다음과 같다. 1. 增體量은 옥수수와 밀을 各各 50%씩 使用한 區와 밀보다 옥수수를 많이 使用한 區가 밀 만을 使用한 區에 비해서 增體量이 좋았다. 2. 飼料攝取量은 옥수수를 제일많이 使用한 區가 제일 적었고, 반대로 밀을 많이 사용한 區 일수록 높았다. 3. 飼料效率은 옥수수와 밀을 50%씩 使用한 區가 옥수수와 밀의 單用區 보다는 좋았다. 4. kg增體에 所要된 飼料費는 옥수수와 밀을 50%씩 사용한 區가 제일 낮아 本 試驗에 의하면 養鷄配合飼料의 穀類 60%中 밀을 30%程度 使用할 수 있다고 하겠다. To investigate the substitute level of wheat for corn used as major ration of laying hen, was carried out. The results obtained were as follows: 1. Body weight gain was higher in the treatment of Corn 50% : Wheat 50% and in used more corn than wheat in contrast with the treatment used only wheat. 2. Diet intake was least in the treatment used only corn and on the other hand, the only wheat was higher than other treatment used corn in the diet intake. 3. Feed efficiency was more improved in the treatment used 50% of wheat and corn, respectively than in the treatment used only wheat. 4. Feed cost required per kg body gain was lowest in the treatment used 50% of wheat and corn. Therefore, according to the present experiment it may be to say that s0% of wheat will be substituted for corn in the formulated ration of laying hen using 60% cereals.

Broiler 雛(Pilch Line)에 Ethyl alcohol(E. A)을 給與시켜서 그 成長에 미치는 영향을 調査하기 위하여 本 實驗을 實施했으며, 各 實驗區는 對照區(C), E.A. 0.3%(T₁), E.A. 0.5(T₂), E.A 0.7% (T₃)로 나누고 各區에 各各 25首씩 配置하여 6週間의 增體量, 飼料利用率, 血液性狀, 斃死率等을 調査한 結果 그 成績에 있어서 약간의 變異는 있었지만 統計的인 有意差는 認定되지 않았다. This experiment was conducted to determine the effect of ethyl alcohol on the growth of chicks. The water was supplemented with 0, 0.3, 0.5, and 0.7% ethyl alcohol. Self-feeding method was taken and other feeding practices and management was according to the custom method. Twenty five broiler(Pilch Line) starting chicks were allowed in each treatment. Growth rate, feed utilization, blood picture and mortality were compared in the 4 treatments during 6 weeks. No significant differences in growth rate, feed utilization, blood picture and mortality were observed between the treatments. From the results of ethyl alcohol effect on the growth of starting chicks in the Journal of the Inrtitute for Agricultural Resource Utilization (1972: Chinju National Agri. College) and the present study, it was concluded that the supplement of ethyl alcohol in such a ratio and method was not effective to increase the growth rate or feed utilization of chicks.

Broiler에 Atonik의 添加效果를 究明하기 위하여 Pilch line Broiler 初生雛 100首를 가지고 Atonil 添加水準 0, 0.3, 0.5, 0.7%를 Completely randomized design에 의해 實驗한 結果를 要約하면 다음과 같다. 1. 增體量에 있어 0.7%를 添加하므로서 약간 改善되었으나 統計的인 有意性이 없었다. 2. 飼料效率은 添加量이 많을수록 떨어지는 경향이 였고 日當增體量은 역시 0.3% 區가 가장 좋았으나 統計的 有意性이 없었다. 3. 血液性狀에 있어 赤血球와 血淸蛋白總量은 對照區에 비해 添加量이 많을수록 增加하였고 白血球와 Hemoglobin 含量은 對照區가 제일 적었다. 4. 斃死率은 各區間에 별차가 없었고 이들은 管理 부주의 및 쥐의 피해였다. This experiment was conducted to investigate the effect of Atonik supplementation on the growth rate, feed efficiency and blood picture of broiler. For this study, 100 starting chickens of pilch line were fed for 6 weeks. Atonik, the plant growth regulator, was supplemented in the levels of 0, 0.3, 0.5 and 0.7% in the water of chicks. The results obtained are summarized as follows; 1. It was found that 0.7% supplementation of atonik slightly improved growth rate but no statistical difference was detected. 2. Feel efficiency was decreased in the treatment given more supplement although no statistical difference was detected. 3. The number of red blood cell and hemoglobin content were increased in the treatment used more supplement hut the number of white blood cell and total serum protein content were decreased in the treatment used more supplement. 4. Mortality was not found tile difference between the treatments.

하정기 ( Jeung Key Ha ) 한국축산학회 1978 한국축산학회지 Vol.20 No.3

To investigate the differences between thickness of egg shell and egg shell membrane in 800 eggs of commercial chicks(400 of Sharer and 400 of Hisex), this experiment was conducted for 10 days from August 16, 1976 to August 25, 1976. All the eggs were purchased from the Yong Gang Poultry farm located in the Sam Chun Po city. 1. A different trend was found out in the egg shell thickness of Shaver and Hisex. In the Shaver egg, no difference was found in the egg shell thickness by weeks of age. However, in the Hisex egg shell thickness was thinner as Hisex grows older. 2. The negative correlation coefficients was found between egg shell and egg swell me mbrane of blunt end, sharp end and middle part in Shaver and Hisex. 3. As oviposition time was prolonged from forenoon to afternoon, egg shell membrane was thinner and egg shell thickness was thicker. 4. It was found that the thicker egg shell the longer time was used in the post period of formation of egg shell in uterus.
