To investigate the nutritive values of Achranthes Japonica Nakai this experiment was carried out for 1 year and 7 months from March, 1976 through October, 1977. Characteristics, yield and chemical composition of Achranthes Japonica Nakai by cutting stages were investigated. The results obtained were as follows; 1. Average plant height of Achranthes Japonica Nakai was 59.5㎝. The plant height at the 2 nd cutting stage was 69.5㎝ and was highest among the cutting stage. 2. Number of tiller of Achranthes Japonica Nakai increased as the cutting stage advanced and number of branch was Rightest at the 1st cutting stage. 3. Achranthes Japonica Nakai produced 4718㎏ of green forage per l0a and produced more yield at the 2nd cutting stage than at and other cutting stages. Dry matter yield of Achranthes Japonica Nakai was 757㎏ per 10a. 4. Crude protein content of Achranthes Japonica Nakai decreased and crude fiber content increased as the cutting stage progressed. The crude protein and crude fiber contents of AchranthesJaponica Nakai showed a great difference by the cutting stages. It may be concluded that Achranthes Japonica Nakai has a similar value compared with improved grasses on the yield and chemical composition, therefore, it could be developed as a forage resource.

This experiment was carried out to investigate the amount of fertilizer application in Coix lacryma L. by the cutting stage. The results obtained were as follows; 1. The grass length was not affected by the amount of fertilizer application in the 1st and 2nd cutting stage. However in the 3rd cutting stage the grass length was significantly (P$lt;0.05) affected by the amount of fertilizer application. 2. The yield significantly (P$lt;0.01) increased as the fertilizing level increased in the 1st and 2nd cutting stage, however, the yield in the 3rd and overall cutting stage was not affected by the amount of fertilizer application. However, treatment-Ⅱ, treatment-Ⅷ and treatment-Ⅸ which were plentiful of nitrogen, phosphorus and potassium produced more green grass than other treatments. 3. Therefore it may be. concluded that the moderate amount of fertilizer application in Coix lacryma L. which is cultivated for green forge was 14㎏ of nitrogen per 10a., 7.5㎏ of phosphorus per 10a. and 11㎏ of potassium per 10a.

This experiment was conducted to investigate the effect of starting body weight on fattening period and body weight gain in short and middle period fattening with the data obtained from the 3 group allotted the starting body weight of 300kg(T3), 250kg(t2) and 200kg(T1) in 15 heads of Korean Native Bulls. The results obtained were as follows: 1. Each average daily weight gain(kg) of 200, 250 and 300kg group was .924, .953 and 1.005 during the experimental fattening period. 2. The fattening period that body weight gain declined, was about 4 months and over after starting fattening. It was suggested that this trend be contributed to the seasonal changes. 3. The consumed fattening period in reaching 420kg at 200, 250 and 300kg group was 230, 189 and 126 days. each. 4. Each DCP and TDN consumed for kg body weight gain a 300, 250 and 200kg group was .874, .885 and .891 and 5622, 5700 and 5733kg. 5. Each daily benefit of 300, 250 and 200kg was 560.17, 657.3 and 723 won. the shorter fattening period was, the higher daily benefit was.

초기배자로부터 분할란의 성(性) 감별과 분할배의 발생 성공은 성의 식별과 더불어 유전적으로 우수한 개체의 생산이 가능함을 의미한다. 따라서 본 연구에서는 새앙쥐(mouse) 및 소의 초기배자 상태의 수정란을 이용한 염색체 분석 기술을 개발하고, 각 수정란의 성의 판별과 이들의 유전적 특성을 구명하고자 하였다. 초기 배자를 이용한 염색체 분리의 최적 조건을 결정하기 위하여 colcemid의 농도, colcemid의 처리시간 및 공시된 배자의 발생단계별 분석을 새앙쥐의 배자로서 수행하였다. 분석 결과 염색체 분리에 있어 colcemid의 처리 시간이 유의적인 차이를 보인 반면 다른 요인들 간에는 별다른 차이가 없는 것으로 나타났다. 소의 체외수정란을 이용한 염색체 분석에서는 공시된 수정란의 93%이상에서 증기상의 유도가 가능하였고, 이들 중 65%에서 성의 식별이 가능하였다. 또한 수정란의 분석된 성비는 1:1로서 자연적 성비와 일치하였다. 염색체 분석에 의한 배자의 조기성 감별은 처리 과정상의 기술적 요인들에 의해 매우 큰 영향을 받는데 특히 hypotonic의 처리방법 및 fixation의 방법을 적절히 처리하므로서 효율적이고 높은 성공률을 기대할 수 있다. Chromosome analysis from biopsied or splitted embryos which were fertilized in uitro or in vivo implicates a possibility of production of the genetical superior animals and sex controlled individuals. Therefore, this study was carried out to develop the technical method for chromosome preparation from early bovine and mouse embryos and to identify their sex and genetic characteristics. To determine optimum condition of chromosome preparation, the several factors which include the concentration of colcemid, the duration of culture and embryonic stage were analyzed from mouse embryos. According to analysis, the duration of culture had significantly influence on chromosome preparation. The other factors were not significantly difference among the treatments. In the results of chromosome preparation from intact bovine embryos, the rate of embryos with one or more metaphase plates was 93%, and of embryos with sex analyzable metaphase chromosomes are 65%. Sex ratio of male and female was approximatly 1:1 same as natural sex ratio. The inducing rate of analyzable metaphase was mainly due to technical aspects, expecially hypotonic treatment and fixation.

This experiment was conducted to investigate the effect of temperature of extrusion processing on ruminal degradation characteristics of soybean meal. Four ruminally cannulated Holstein cows were employed to in situ trial and treatments were composed of soybean meals untreated(Control), extruded at 115, 130 and 155℃, and treated with 0.3% formaldehyde(HCHO). The nylon bags were suspended for 0, 3, 6, 9, 12 and 24 hours in the rumen, respectively. Animals fed the diet of 50 : 50 in concentrate and orchard grass hay at 110% of NRC(1988) requirements, and were freely access to water and mineral block. The regression equations for degradation characteristics and effective degradability(ED) of crude protein of soybean meals in the rumen were obtained as follows. Control P = 26.41 + 69.86(1-e^-0.041t) ; ED(k=0.05) = 57.89% 115℃ extrusion P = 3.39 + 44.76(1-e^-0.013t) ; ED(k=0.05) = 12.63% 130℃ extrusion P = 2.79 + 56.60(1-e^-0.015t) ; ED(k=0.05) = 15.85% 155℃ extrusion P = 1.71 + 31.48(1-e^-0.018t) ; ED(k=0.05) = 0.04% 0.3% HCHO P = 7.23 + 35.14(1-e^-0.015t) ; ED(k=0.05) = 15.34% where, P = Degradability during the time(t) suspended in the rumen, k = Passage rate at the rumen(%/hr/100). Ruminal degradabilities of dry matter, crude protein, organic matter and energy significantly (P<.01) decreased by extrusion or HCHO treatments, but did not affected by the temperature of extrusion processing. The ruminal degradation of soybean meals treated extrusion and formaldehyde, paticularly crude protein, was low beyond expectation.
