The present study,a continuation of the work in 1961,was conducted with the purpose of futher improvement on sperm vitality by modifying the composition of different diluents.Three experiments were designed.In the 1st experiment effects of 6 diluents with different composition on preserving boar semen at 13-18℃ were compared,while in the 2nd experiment to determine the optimal content of egg-yolk,and in the 3rd to determine the optimal level of anti-bacterial agents.10,12 and 12 ejaculates from 2 boars were used in 1st,2nd and 3rd experiments respectively,and various treatments were made from each ejaculate by using split sample technique.The dilution rate was 1: 2.In 1st experiment,the longest duration of survival (373.6±17.3hrs.) and highest vitality index (140.4±5.4) of spermatozoa were obtained in milk-citrate-glucose-yolk diluent.More-over,during storage the motility rate of spermatozoa in this diluent remained on a higher level as compared with those in the others.The motility rate of semen samples stored for four days remained over 0.6.Milk-glucose-yolk Ⅱ and glucose-yolk showed to be inferior to the diluent described above,but were better than the other three extenders consisting of milk,sodium citrate and egg-yolk.In the 2nd experiment,it was found that,the glucose-yolk containing 20-30% of egg-yolk gave best results,while in the milk-citrate-glucose-yolk,extender,the optimum egg-yolk content was at a 10-20% level.Data of the 3rd experiment showe'd that,better results could be obtained only when penicillin,streptomycin and sulfanilamide were used together.In general,500-1000 I.U.of penicillin,500-1000μg.of streptomycin and 1-3mg.of sulfanilamide per ml.of diluent were optimal. Based on the results of investigations,the following three extenders may effectively preserve boar semen at 13-18℃.,which can be easily obtained under field conditions (in vacuum flask filled with cold water,or at room temperature in cold seasons).After storage of three days in these extenders,the motility rate of spermatozoa remained over 0.5,i.e.more than 50% of spermatozoa showing progressive movement. 1.Milk-citrate-glucose-yolk—heated milk (at 92-95℃. for 10 min),2.9% sodium citrate dihydrate solution and 5% glucose solution mixed in equal parts,10-20% egg-yolk of final concentration added. 2.Milk-glucose-yolk Ⅱ—heated milk mixed with 5% glucose solution (ratio 1: 3),10% egg-yolk of final concentration added. 3.Glucose-yolk—5% glucose solution mixed with egg-yolk in ratio of 7: 3 or 8: 2. In each ml.of extenders 500-1000 I.U.of penicillin,500-1000μg.of streptomycin and 1-3 mg.of sulfanilamide included.

本研究是在1961年猪精液保存試验的基础上从改变保存液成分进一步提高精子的存活能力。共进行了三个实驗,在第一实驗中比較了6种成分不同的保存液在13—18℃下保存猪精液的效果。第二实驗和第三实驗是測定保存液中卵黄和制菌物质的适当含量。在三个实驗中,由两头公猪分別采取10,12和12次的精液,并将每次精液以样品平分法进行不同处理。稀释比例均为1:2。第一实驗的結果說明,精子在奶-檸-糖-黄保存液中的存活时間最久(373.6×17.3小时),存活指数亦最大(140.4±5.4)。在保存期間,精子活率此在其他数种保存液中維持較高的水平,保存4天活率仍在0.6以上。奶-糖-黃液Ⅱ及糖-黄液的效果虽然較上述一种为差,但优于共他三种奶-檸-黄液。第二实驗的結果确定在糖-黄液中当卵黄含量为20—30%时,所得結果最好,而在奶-檸-糖-黄液中,則以10—20P6的卵黄含量較为适当。第三实驗說明,在保存液中需要按一定的量同时添加青霉素、鏈霉素和氨苯磺胺三种制菌物质才能得到較好的結果。一般說来,每毫升保存波中上述三种制菌物质的适当含量分別为500—1000单位,500—1000微克,1—3毫克. 根据本研究的結果,在通...

1 . Comparative studies of growth of bones, skin, muscles, fat and internal organs of 3 different groups of pigs were made. 14 weaned pigs of either Kwangtung Large White-and-Black breed (local breed),F, crossbred (KLWB× Berkshire) or offsprings of self-crossed backcrossbred were allocated to one of the 3 groups respectively. All the pigs used are males, castrated at the age of one months old. Two pigs of each group were killed at an interval of every two months, begining from birth to one years old. Self-crossed hogs, showed better results in weight gain, body conformation, meat production and higher dressing percentage than Kwangtung Large White -and -Black hogs. It may thus be said that the back -crossed offspring inherited the ability in having better body conformation, weight gain and more meat production from Berkshire breed and a good extent of adaptiblity -in utilizing feeds and to environmental conditions from local breed, although F1 crossbred hogs surpassed them somewhat in body conformation and weight gain. 2.The study on growth of bones, skin, muscles and fat revealed in such order : the growth of bones in local breed, F1 crossbred and self -crossed hogs started early and advanced steadily; the growth of skin and muscles ranked second with fat the latest, As to the growth of mnscles, a difference in relation to age existed, the rate of its growth for local breed up to 6 months old was apparently declining; that of F1 crossbred hogs began to decrease at age of 10 months old, only that of self-crossed hogs from 4 months onward maintained fairly constant. As to the fat growth, the local breed showed an intensive rate of growth since 4 months old; F1 crossbred hogs-frotn 4 months onward,the rate of growth increased gradually but was hastened after the age of 10 months old; while that of self -crossed hogs grew steadily from 4 to 12 months old.It was thus odserved that the growth of muscles for Kwangtung Large White-and-Black hogs covered a comparatively shoat period with fat starting early and growing intensively, that for F1 crossbred and self -crossed hogs lasted a longer time but with the growth of fat in self -crossed hogs appeared later and assumed a slower rate only. 3. ln regard to the growth of skeleton,the rate of growth along vertebral for Kwangtung Large White-and-Black breed occurred more intensive in thoracic vertebrae than any other parts of bony skeleton, but for F1 crossbred and self -crossed hogs were in lumbar vertebrae. In the fore -limbs, the growth of scapula and humerus appeared most intensively as well as pelvis and femur in the hind limbs for all the hogs of three groups.4. The growth of muscles in different parts was also compared, intensive growth ranked first in pelvic region, next in lumbar region for F1 hybrid and self -crossed hogs, and for Kwangtung Large White-and -Black hogs abdominal muscles grew faster than those- in trunk and lumbar regions.

用42头广东大花白品种猪、杂种一代猪(巴克夏品种公猪×广东大花白品种母猪)以及回交自繁后代猪(大花白品种公猪×巴杂一代母猪,并经横交自群繁殖)的去势小公猪,分三组,每组14头进行试验。观察三组猪从出生至12月分期间的增重、发育,饲料利用效能,同时把每组试验分别于出生、2、4、6、8、10及12月令等7个阶段每次屠宰二头,进行尸体分解,研究其骨骼、皮肤、肌肉,内部主要器官及组织的生长。 试验证明,回交自繁后代猪在增重、发育、饲料利用效能及产肉性能上均比大花白猪有明显的改进。对肌肉生长的观察,表明大花白猪的肌肉生长期限比回交自繁后代猪和杂种一代猪短暂;而脂肪的生长期,大花白猪又比回交自繁后代猪及杂种一代猪早且强烈。 头骨、颈椎等前部骨骼为早期生长的骨骼,早期令时生长己趋于稳定;而离头骨越远的脊椎骨(如腰、荐椎)均属于后期生长强烈的骨骼。四肢骨中以靠近脊椎骨的肩胛骨、肱骨、盆骨及股骨为后期生长迅速的骨骼。 臀部肌肉是在后期生长最为强烈,在回交自繁后代猪及杂种一代猪中得到证实。皮下脂肪的生长是随着年令的增长从体躯中部向体躯后部渐次加强。

Brucella suis strain 2 is an old laboratory strain which was attenuated naturally after serial transfer on media for years.It shares all of the characteristics of Br.suis biotype I and is of smooth type.The virulence of the strain is a little higher than that of strain 19,but much lower than that of the pathogenic strain of Br.suis.When injected in large doses of about 10~9 live cells into guinea pigs,strain 2 gave a spleen count of about 2×10~4-6×10~4 organisms at 14-15 days after injection, strain 19 gave about 1×10~4-5×10~4,Ray.I gave about 12×10~4-14× 10~4 and Br.suis pathogenic strain 1330,strain 12 and strain 14 gave about 280×10~4-4200×10~4 Inoculation of pregnant sows with 50×10~9 live cells of strain 2 did not cause abortion or infected parturition,whereas inoculation with 5×10~4-15×10~4 cells of a virulent strain of Br.suis always did so.In boars inoculated with 18.6×10~9 live cells of strain 2 and killed 45 days after injection,no brucella was recovered from their lymph nodes and internal organs examined,whereas in those inoculated with about 10~5 organisms of a pathogenic strain of Br.suis,39-60% of their lymph nodes and organs yielded brucella. The avirulent property of Br.suis strain 2 was found to be stable when inoculated into susceptible animals.After passaging 5 times in guinea pigs,5 times in pregnant sheep,4 times in pregnant goats,4 times in pregnant sows or 5 times in boars,the virulence of the strain remained unchanged as evidenced by the fact that the spleen count it gave in guinea pigs remained at the same level as the stock culture gave. Br.suis strain 2 is able to provoke a good immunity in guinea pigs and goats.In 4 experiments,39 guinea pigs were vaccinated with strain 2,26 were vaccinated with strain 19,22 were controls.Forty-five days after vaccination,they were challenged with a virulent strain of Br. melitensis and 30 days later they were killed.Bacterial cultures were made of lymph nodes an internal organs and the infection indexes (No.of organs infected/No.of organs cultured×100)of the vaccinated and the control groups were calculated.It was found that the infection indexofthe strain 2 vaccinated group was 6.5 only,of the strain 19 group 28.2,and of the control group 88.9.Good results were obtained from goats also.In two experiments,12 goats were vaccinated with Strain 2,3 were vacci- nated with strain 19,8 were controls.Three months after vaccination they were challanged with Br.melitensis and 45 days later they were killed for bacteriological examination.The strain 2 vaccinated group showed an infection index of 4.9%,the strain 19 group showed 13.3%,the control group showed 38.9%.strain 2 gave the better protection against Br. melitensis infection.

布氏菌猪二号菌种是一株在人工培养基上长期移植传代而自然变弱的菌种,用豚鼠测毒时,它所产生的脾脏含菌量与牛型19号菌种所产生的相近似,而比强毒猪型菌种产生的约低100~500倍。给怀孕猪皮下注射本菌种的500亿活菌,不引起流产,而注射强毒猪型菌种的5~15万个菌,即可引起流产或正产排菌;给性成熟公猪皮下注射500亿活菌,在体内活存不到45天,而注射强毒猪型菌种的10万个菌,经过45天剖检,仍有35~67%器信出菌。可见猪二号菌种对其天然宿主的毒力比性毒猪型菌种低30~100万倍以上。猪二号菌种的弱毒性在易感动物体内是稳定的。连续通过豚鼠5代,怀孕猪4代、怀孕绵羊5代和怀孕山羊4代,毒力都不增强。猪二号菌种对豚鼠和非怀孕羊具有较好的免疫原性。
