The polled goat of Chengde has blocky body and high percentage of clean meat and could be breeded on every season. Among the population the black goat occupy 70% and the white one is 30%, which fleece structure is composed of 3 wool fibers. The polled goat is weighter than horn goat. The average daily gain of the male and female spring—born kid of polled goat was 118.9g and 107.8g respectively in six age months. The weight of head of the mature of polled goat, is 1.63+0.29kg the horn goat is 2.06+0.44(P<0.01). The scurs of polled goat are of two kind, the round and the ovat, both surface are covered by furs. For polled goat the trachea is composed of 42—53 cortilage loops, average length is 32.7cm, of which flat structure forms 14.4%.

承德无角山羊,体大肉多,净肉率高,多季节繁殖。该羊头较短而宽,体躯呈长方形,黑色毛被占70%,白色毛被占30%,其毛被结构由三种纤维组成。无角山羊体重比有角山羊大,公母春羔在六个月内平均日增重分别为118.9克和107.8克,成年无角山羊头重1.63±0.29公斤,有角山羊2.06±0.49公斤(P<0.01)。无角山羊角基分园形和椭园形两种,表面均有皮毛复盖。无角山羊的气管是由42—53个软骨环组成,平均长度为32.7厘米,在气管长度内有14.4%呈扁平结构。消化系统比有角山羊发达。

Late morulae, blastocysts, hatched blastocysts and expanding hatched blastocysts from superovulated crossbred Saanen dairy goats and Shaanbei black goats were bisected with a microblade. Nineteen pairs of zona-free demi-embryos were transfered into 18 recipients, and 12 became pregnant. Two of the recipients which received bisected blastocysts lost their fetus at about day 60 of pregnancy, another two which received bisected hatched blastocysts aborted a single fetus at day 70 and 80 respectively.

Late morulae, blastocysts, hatched blastocysts and expanding hatched blastocysts from superovulated crossbred Saanen dairy goats and Shaanbei black goats were bisected with a microblade. Nineteen pairs of zona-free demi-embryos were transfered into 18 recipients, and 12 became pregnant. Two of the recipients which received bisected blastocysts lost their fetus at about day 60 of pregnancy, another two which received bisected hatched blastocysts aborted a single fetus at day 70 and 80 respectively. The remaining 8 recipients went to term, producing 11 half embryo kids. The success rate of demi-embryos reaching full term from morulae, blastocysts, hatched blastocysts and expanding hatched blastocysts was 12.5% ( 1/8 ), 20% ( 2/10), 25% ( 3/12), and 62.5% ( 5/8 ) respectively. No monozygotic twins were obtained in the first three groups. Three of the 4 recipients which each received a pair of demi-embryos from expanding hatched blastocysts became prognant, and 5 half embryo kids were obtained at delivery, including 2 pairs of monozygotic twins. The present study demonstrated that the expanding hatched blastocysts in goats are suitable for bisection by the simplified procedure to produce monozygotic twins.

选择山羊晚期桑椹胚、囊胚、孵出囊胚和孵出增大胚泡,用简化分割法二分。将19对裸半胚移植于18只受体羊,结果有12只妊娠,其中两只胚胎消失,两只流产,其余8只足月分娩,共产半胚羔11只。晚期桑椹胚、囊胚、孵出囊胚和孵出增大胚泡各组的半胚发育为羔羊的发育率分别为12.5%(1/8)、20%(2/10)、25%(3/12)和62.5%(5/8)。前三组均未获得同卵双生羔羊。在第四组,将4对裸半胚移植于4只受体,有3只妊娠,足月分娩半胚羔5只,其中两对为同卵双生。本研究证明,对称分割山羊孵出增大胚泡,不仅其半胚在体内仍可继续发育形成正常胎儿,而且不装透明带移植其裸半胚,仍能获得较高的同卵双生率。山羊孵出增大胚泡更适宜用简化分割法分割。

The secondary oocytes from Saanen dairy goats and 4-32 cell embryos from Shaanbei black goats were used as cytoplast donors and karyoplast donors respectively. The blastomeres separated from the embryos were injected into the perivitelline space of enucleated secondary oocytes under the control of micromanipulator. Membrane fusion between blastomeres and enucleated secondary oocytes was accomplished by electrofusion. Culture in vitro and transfer of nuclear transplanted embryos were carried out in order...

The secondary oocytes from Saanen dairy goats and 4-32 cell embryos from Shaanbei black goats were used as cytoplast donors and karyoplast donors respectively. The blastomeres separated from the embryos were injected into the perivitelline space of enucleated secondary oocytes under the control of micromanipulator. Membrane fusion between blastomeres and enucleated secondary oocytes was accomplished by electrofusion. Culture in vitro and transfer of nuclear transplanted embryos were carried out in order to evaluate the results of nuclear transplantation performed in different conditions. The present study demonstrated that (1) no effect of embryo stages for karyoplast donors on survival rate in vitro of nuclear transplanted embryos was found at 4-32 cell stages; (2) nuclear transplanted embryos produced by transferring blastomeres from 4-32 cell embryos into enucleated secondary oocytes can develop into normal kids in vivo; (3) higher survival rate of nuclear transplanted embryos in vitro can be obtained when secondary oocytes collected at 25-35 h after LH injection were used as cytoplast donors; (4) electrofusion results can be improved when inducement with two 900 V/cm DC pulses of 80μs. On the basis of RNA transition found at 2-cell stage in goat embryos and the results of the present study, the authors think that the cytoplasm of secondary oocytes may possibly have the function of dedifferentiating the nuclei transplanted from embryos at late cleavage stages.

选用陕北黑山羊的4-32细胞胚和萨能奶山羊的次级卯母细胞分别作核供体和胞质供体。在显微操作仪的控制下,将分离后的单个卵裂球注入去核次级卵母细胞的卵周隙。采用电融合法诱导卵裂球和去核次级卵母细胞融合。通过体外培养和移植,检查卵核移植的效果。本研究证明:(1)在4-32细胞期,核供体胚的发育阶段对山羊卵核移植胚的体外发育无显著影响;(2)由山羊4-32细胞期胚胎的卵裂球和去核次级卵母细胞构成的卵核移植胚在体内仍可发育为正常个体;(3)用注射LH后25-35小时的次级卵母细胞作胞质供体均可获得较高的卵核移植胚体外发育率;(4)用900伏/厘米的电场强度进行2个80微秒的电脉冲处理,诱导卵裂球和去核次级卵母细胞融合可获得更好的电融合效果。根据山羊胚胎性RNA在2细胞期出现的事实和本研究的上述结果,作者认为,次级卵母细胞的胞质对移入的晚期卵裂胚细胞核可能有去分化作用。
