Effect of Adding Alfalfa Meal and Fat to the Diet of Sows on Their Reproductive Capability and Mechanism Abstract In this experiment, a single-factor and randomized block design was used comprising of 20 sows and 160 sucking piglets to study the effect of adding alfalfa meal and fat to the diet of sows on their reproductive performance. The results are as follows: 1 .The birth weight, daily gain and weaning weight of the piglets were highly significantly improved (P.01) which were born of the sows eating diet with adding of alfalfa meal and fat.

本试验共用了20头母猪和160头哺乳仔猪采用完全随机区组单因子试验方法，进行了一定比例苜蓿草粉和定量脂肪代替部分精饲料对母猪繁殖性能影响及其机理的初步研究，结果如下：（1）在母猪的妊娠后期和哺乳期添加一定比例的苜蓿草粉和定量脂肪（1.6％），可显著地提高哺乳仔猪的日增重、断乳个体重和窝重（P＜0.01）。

And nutrition at some stage may influence performance of sows of this stage,next stage and the whole reproductive cycle.

近年来，随着集约化生产的发展，高产仔母猪的营养需要和饲养管理已成为动物营养研究的新热点，有必要对其进行深入研究。1不同阶段妊娠母猪的饲喂母猪的繁殖性能与繁殖周期的各阶段营养密切相关，某一阶段的营养会影响此阶段、后一阶段乃至全程的生产性能(Johnston和Trottier，1999a)。

By finishing the breeding records of 850 parities Landrace sows and 470 parities Yorkshire sows from the breeding stock farm in Nanchong City, Sichuan Province, the effects of the interval from weaning to the breeding and gestation period on the reproductive performance of sows were studied.

通过整理四川省南充市种畜场850窝长白母猪、470窝约克夏母猪的繁殖记录，研究了断奶至配种间隔、妊娠期对长白和约克夏母猪繁殖性能的影响。

The pathological lesion rate caused by local pneumonia for the progeny swinery of the first-born sows was 3/%, and that for the second -born breeding sows was 11%, being 30% of the pathological lesion rate in the first-born sows, so the health level of more than the second-born breeding sows was more stable.

头胎母猪后代的地方性肺炎痛变率为31%，二胎以上母猪后代的地方性肺炎病变率是11%，为头胎母猪后代发病率的1/3，稳定了二胎以上母猪的健康水平。

The first-born, second-born and third-born breeding sows were separated to be fed, after that they were artificially fecundated. The progeny swinery of the first-born and more than the second-born breeding sows were separated to be fed and the annual production litter size and pathological change of local pneumonia for breeding sows etc.

方法］将头胎、二胎、三胎母猪分开饲养后进行人工授精，并将一胎母猪后代猪群与二胎以上母猪后代猪群实行隔离饲养，记录每头母猪年产仔数和地方性肺炎病变等数据。

Evening the boar always stands sentry to the sow, his for fear thatmaster slept soundly while them when pulls out the sow butchered A day daily past, the sow gained weight day after day, but boar thenone thinly got down daily One day, the boar suddenly hears the master in to discuss with thebutcher that, must the sow which improves the growing trend kill hasgiven sells out, boar sadly to extremely Thereupon starts the boarpersonality from that day greatly to change, when the master deliverseats the boar always to rush ahead clean which eats the thing, afterevery day eats then lies down greatly rests, and tells the sow now totrade is her to stand sentry, if he discovered she has not stoodsentry the speech again also pays no attention to her.

After the RT-PCR detection of the total RNA from heart tissue, we found that the CD59 gene and MCP gene were expressed. 4. The CD59 gene and MCP gene were mixed with liposome, then used to produce transgenic swine by 3 methods. Firstly, the gene/ liposome complex was directly injected into male swine's testis. The transfected males copulated with 8 females each 44 days later.

其中睾丸注射法处理公猪1头，44d后配母猪8头，7头受孕，产仔73头，结果检测到PCR阳性猪3头(阳性率4.3%)；输精管注射法处理公猪3头，8d后配母猪3头，0头受孕；外源基因/精子共孵育法处理公猪4头，处理母猪4头，1头受孕，产仔11头，结果检测到PCR阳性猪1头(阳性率9%)。
