소의 受胎率 向上을 위한 Prostaglandin F₂α의 效果에 관한 硏究

宋又準,張判亨 慶尙大學校 1980 論文集 Vol.19 No.1

분만 후 3個月 이상 기능적 황체나 낭종성 황체에 의하여 空胎되고 있는 乳牛 49두에 대하여 Prostaglandin F2α를 투여하여 發情 및 배란을 유도하고 受胎시험을 실시한 결과는 다음과 같다. 1. 本 患畜이 1두 이상 있는 30호의 농가에서 조사한 本症의 발생율은 17%로 나타났으며 평균 空胎期間은 6.0個月 내지 그 이상이었다. 2. 합성 PGF2α인 cloprostenol을 28두의 患畜에게 500μg 1회 근육 주사한 결과 주사 후 평균 3.5일에 93%의 發情이 발현되었고 46% 이상의 受胎成績을 보여주었다. 3. Cloprostenol을 4두의 유?實質에 125μg 1회 주사한 결과 주사 후 평균 3.3일에 모두 發情이 발현되었으며 2두에서는 受胎가 확인되었다. 그러나 주사기술이 힘들어 불편하였다. 4. Cloprostenol을 陰唇粘膜下에 125μg(5두), 250μg(12두)에 1회 주사한 결과 125μg 처리에서는 주사 후 10일까지 發情의 발현이 全無하였으며 250μg 처리에서는 83%가 주사 후 평균 3.8일에 發情이 발현되었으며 25%이상의 受胎를 확인하였다. 이상의 결과로 미루어 보면 기능적 황체나 낭종성 황체에 의한 無發情牛에 대하여는 陰唇粘膜下에 250μg 을 1회 주사하여 치료하는 방법이 가장 실용적이라 하겠다. Cloprostenol(a PGF2α analogue) was injected experimentally to 49 heads of Holstein cows on lthe farm in Jinju area. These cows were diagnosed to be anestrual from the functional or cystic corpus luteum over 3 months after calving. The cows showing estrus by this treatment were inseminated artificially and the pregnancy test was carried out by rectal palpation. The practical use of the various methods of injection was compared. The results obtained are summarized as follows: 1. The incidence of this symptom was found 17% in the farms where more than 1 cow was diagnosed to be suffered from the condition, and the average duration of anestrus after calving was longer than 6.0 months. 2. Of 28 cows injected with 500μg of cloprostenol intramuscularly, 26 cows(93%) showed estrus on the average 3.5days after treatment and the conception ratio was estimated higher than 46%. 3. All of 4 cows treated with intraovarian injection of 125μg of cloprostenol showed estrus on the average 3.3 days after treatment and 2 cows were identified to be pregnant. However, the technique was considered to be somewhat difficult. 4. Of 5 cows and 12 cows treated with intravulvosubmucous injection of 125 or 250 μg cloprostenol, no cows and 10 cows(83%) showed estrus on the average 10 days and 3.8 dasys after treatment, respectively, and the conception ratio was found 25%. From the above results it was concluded that the intravulvosubmucous injection of 250μg cloprostenol was better as a treatment for anestrus from functional or systic corpus luteum in cows.

32 White rabbit furs of which, 16 of winter (Jan.) and another 16 of summer (Aug,) irrespective of breed origin, were sampled and treated by four different methods: chrome dressing, alum dressing, acid dressing, and milk dressing. Tensile strength, Elongation, Heat resistance were tested respectively and the results between the treatments were compared; (1) In Tensile strength, 1% level high significance was observed between chrome dressing and others, while there was no significance between January and August dressings. (2) In Elongation, chrome dressing of August was the most satisfactory and acid dressing of January vice versa. In seasonal difference, every dressing of August was superior to others and 1% level high significance was observed between August chrome dressing and other dressing. (3) In Heat resistance, between chrome and other dressing was 1% significance and August acid dressing was the least efficient. (4) In seasonal aspect, every dressing of January was prefered to that of August, with the exception of Elongation, and the preference was chrome, milk, acid and alum. (5) Chrome dressing was superior to others in many ways. But, considering its complexity and the tendency toward spoiling pure whiteness of fur, milk dressing is thought to be ideal in farm-scale dressing.

1. This study has been conducted to test the mater permeability and the water absorption of dressed bare fur which was stripped from four heady of eight month aged rabbits in each season, summer and winder, irrespective of bred origin, These stripped hare furs were treated with different dressing methods such, as chrome, acid, alum and milk dressings. The water permeability and the water absorption were measured with the regular methods. The obtained data for the treatment, four dressing methods under two seasons were statistically analyzed. 2. There was no significant seasonal difference in water permeability and water absorption. There were, however, highly significant differences between dressing methods in the water absorption. In the permeability, there was also no significant difference between seasons but there were highly significant difference between dressing methods. On the contraly, evaluating the superiolity of dressed hare fur in terms of it durability and water proof ability, goodness were in following order; chrome, acid, milk, and alum dressing. 3. These obtained results of physical properties if dressed Rabbit fur that chrome dressing was most desirable method, while alum dressing was worse one. Whereas, milk and acid dressing were almost same.
