    A strain of hog Cholera virus has been adapted and maintained 430 passages in rabbits over past four more years. This virus strain readily multiplied in rabbits and it caused high and relatively durable hyperthermia. A series of experiments were performed on pigs in both laboratory and field trials and it was proved that the vilulence of the virus has been gradually and markedly attenuated to pigs after lapinized through rabbits. Before early 90 passages it caused mortality to both weaned and suckling piglets. Thereafter, pigs from 62 herds were vaccinated With viruses from 91 to 165 rabbits passages only developed less reactions and mortality indicating further attenuation. But some of those suckling piglets of unthrifty condition died from enteritis complications following post-vaccination reactions, The Virus has been proved to be markedly attenuated after 156 more rabbits passages by the facts when pigs of different ages including 10 to 40 days suckling piglets vaccinated with the virus of the 214th and later passages without showed any subclinical reaction and there were no bad effects to their growth. During 1957, the virus after 300th passages was used as seed in preparing vaccines in many provinces, a total of 6752601 pigs of different ages and weights were vaccinated. The multiplication of the virus in pigs is occassionally accompanied by slight febrility. Generally no clinical reactions could be observed and slight loss of appetite was exhibited only by animals in poor condition of health. No post-vaccination losses occurred, although large doses of the virus were given. Further safety tests of the vaccine were performed and proved that the attenuation of the virus was quite reliable and safe. 15 days suckling piglets were perfectly healthy after inoculated with the virus which had been turned back to susceptible pigs for 6 serial passages and this indicated the stability of virulence of the lapinized vaccine for pigs. The vaccinated animals excreted no virus from urine or keep infective virus within the body for long intervel. Unvaccinated animals were kept with vaccinateb ones for 60 days. Every unvaccinated contact proved susceptible to challenge with virulent virus, performed 2 months after vacination. In our experiments the vaccination proved entirety safe for suckling pigs, which also developed relatively high degree of immunity. In several state farms a total of 191 sows in different stages of pregnancy were vaccinated. The animals exhibited no side reaction whatever and delivered normal fetouses. According to our results the attenuated rabbits virus has been considered to be an ideal live vaccine for hog cholera control, so that it has been used for mass vaccination within the whole country since 1957. More than 300 millions of vaccine doses have been inoculated in the field, and the results were reported to be quite safe and satisfactory. Since 1956, this Chinese or “K” strain of lapinized HC virus was introduced into USSR, Hungary, Bulgaria. DPRK, Romania, Vitnan and then other countries. The results of comparative experiments and successful mass vaccination in the field over many years in different countries have comfirmed that this C_strain of HC vaccine is very safe and has excellent immunogenicity. This live virus vaccine was considered an excellent tool in preparing the ground for the complete eradicaton of HC, such as new achieved in DPRK, Hungary, Bulgaria and some other European countries.

    通过四年多的试验证明,猪瘟病毒由于连续通过兔体传代适应后,对猪的致病力,发生了明显的变化,通过兔体67代以前,对吃乳猪和断奶猪均不安全有死亡,用91代以后,165代以前各代兔化毒,在各农场试验,对断奶仔猪的死亡率降低,毒力减弱;但对某些少数体弱及饲养条件欠佳的吃乳猪群,仍会因反应诱发并发病死亡。到214代以后用于各龄仔猪包括生后10—40天的吃乳猪,已极安全,无可见反应,不影响发育。自1957年在全国广泛应用,平均反应率约1%,死亡率约0.1%(包括各种原因死亡在内,此时种毒为300代以后),说明兔化毒对猪的毒力已充分减弱。从其对猪的毒力演变过程来说,毒力减弱是随通过兔体传代数增加,而逐渐发生变化的。本试验还进一步证明了兔化毒毒力减弱后的稳定性,这株病毒虽连续回归通过易感仔猪6代,对生后15天的吃乳猪仍很安全。可以说,对猪的毒力并未增强,即使大量静脉注射仔猪也未发生可见反应。兔化毒免疫猪,不排泄病毒,猪体内也不长期保毒,与健康猪同群饲养,并不发生接触感染。免疫生后10—40天的吃乳猪,不影响其发育,初步观察对怀孕22天—3.5月的母猪,不发生流产,正常产仔。各省区在应用期中,也曾仔细观察兔化毒对吃乳猪和仔猪的...

    通过四年多的试验证明,猪瘟病毒由于连续通过兔体传代适应后,对猪的致病力,发生了明显的变化,通过兔体67代以前,对吃乳猪和断奶猪均不安全有死亡,用91代以后,165代以前各代兔化毒,在各农场试验,对断奶仔猪的死亡率降低,毒力减弱;但对某些少数体弱及饲养条件欠佳的吃乳猪群,仍会因反应诱发并发病死亡。到214代以后用于各龄仔猪包括生后10—40天的吃乳猪,已极安全,无可见反应,不影响发育。自1957年在全国广泛应用,平均反应率约1%,死亡率约0.1%(包括各种原因死亡在内,此时种毒为300代以后),说明兔化毒对猪的毒力已充分减弱。从其对猪的毒力演变过程来说,毒力减弱是随通过兔体传代数增加,而逐渐发生变化的。本试验还进一步证明了兔化毒毒力减弱后的稳定性,这株病毒虽连续回归通过易感仔猪6代,对生后15天的吃乳猪仍很安全。可以说,对猪的毒力并未增强,即使大量静脉注射仔猪也未发生可见反应。兔化毒免疫猪,不排泄病毒,猪体内也不长期保毒,与健康猪同群饲养,并不发生接触感染。免疫生后10—40天的吃乳猪,不影响其发育,初步观察对怀孕22天—3.5月的母猪,不发生流产,正常产仔。各省区在应用期中,也曾仔细观察兔化毒对吃乳猪和仔猪的安全性,未报告有什么不良反应产生。河南、陕西曾用以接种生后3天的吃乳猪,也没有什么反应,发育正常。不论根据实验室和在全国广泛实践应用的结果,均证明猪瘟兔化毒对猪的毒力已显著减弱,而对猪的免疫力仍很坚强,与国际文献所报导的其他各国应用的猪瘟弱毒株相比,品质是优良的。可以说是一株理想的猪瘟活毒疫苗弱毒株。从1956年开始,先后供给苏联、越南、匈牙利、罗马尼亚、保加利亚及朝鲜人民民主共和国等国应用,已分別取得控制或消灭猪瘟的良好效果。

    Embryos were obtained from dairy cows after superovulation which was induced by intramuscular injection of FSH with a total dosage of 500—600 RU per cow commencing on day 15 or 16,with a daily dosage of 100—150 RU in two injections within 4—5 consecutive days. With the aid of a two-way catheter inserted into the cervix ute- ri,embryos were recovered on day 6,7 or 8 after artificial insemi- nation.In 1978,17 out of the 26 donors (65%) delivered 38 ova,33 were fertilized eggs.This gave a recovery rate of 1.3 embryos...

For embryo transfer,an insemination catheter was introduced into the cervix uteri of the recipient and eggs with medium were poured in.In 1978,20 embryos were transferred to 18 recipients.4 recipien- ts were pregnant,3 of them had born 4 calves,and the other one aborted on the third month of pregnancy.The pregnancy rate and the embryo survival rate were 22% and 20% respectively.

    SUMMARY In bactrian camel the average gestation period counted from the day of ovulation is 2102,2+11.53 (with a range of 374—419) days. The corpus luteum verum averages 2.6(1.8—3.5) cm in diameter (or long axis), i.e.much larger than the corpus luteum spurium. Almost all of the fetuses are located in the left horn. Pregnancy diagnosis by rectal examination is described in detail.
