This experiment was conducted in effort to determine safety and proper amount of Urea, Coating urea and Diuredo-isobuane (DUIB) in Korean Native Goats. The results obtained were as follows: 1. Ruminal pH values were considerably higher (7.0-8.0) on area and coating area treated goats. But constant ruminal pH values were recorded on DUIB treated goats. 2. Ruminal ammonium nitrogen concentration were below toxic levels when treated with coating urea (0.77 gm/kg B.W.) and DUIB (1.28 gm/kg B.W.). Although urea (0.3 gm/kg B.W.) were slightly above toxic levels. 3. Blood ammonium nitrogen concentration were below toxic levels when treated with urea (0.3 gm/kg B.W.) coating urea (0.77 gm/kg B.W.) and DUIB (1.28 gm/kg B.W.) 4. Korean Native Goats used were intoxicated by 0.9 gm urea per kg B.W. and 2.33 gm coating urea per kg B.W. between 40 minutes and 80 minutes after administration. 5. Initial rise in ruminal pH and blood ammonium nitrogen concentration was a tendency for a decline after 4 weeks feeding urea (0.3 gm/kg B.W.) and coating urea (0.77 gm/kg B.W.) (p<0.05). The present data reveal that DUIB is most efficient NPN resource in Korean Native Goats.
宿主의 性Hormone이 소진드기 Boophilus microplus의 산란에 미치는 영향에 대한 실험적 연구
房極勝 東亞大學校 1975 東亞論叢 Vol.12 No.2
性 Hormone齊를 소진드기 Boophilus microplus에 주사 하여 본 결과 다음과 같다. 1. Estrogen은 産卵前 휴식기간을 연장하고 산란을 억제 하는 效果가 있었다. 2. Progestron은 産卵活動에 뚜렷한 영향을 주지 않았다. 3. Testosterone 은 진드기의 初期 産卵을 촉진하는 效果가 있었다. 4. 性 Hormone이 産卵 지속기간, 産卵한 卵數에는 영향을 주지 않는 것으로 나타났다. This study was conducted to study the effect of host sexual hormone on egg laying of cattle tick. Boophilus microplus. The results were as follows: 1. Female sex hormone, Estradiol, markedly inhibited egg laying and resting period for egg laying. 2. Female sex hormone, Progestrone, showed no significant effect on egg laying activity. 3. Male sex hormone, Testosterone, acclerated egg laying especially in the early stage of egg laying period. 4. Above three sexual hormone showed no significant effect on the number of egg laid and duration of egg laying period.
