E gre tta, garzetta), Black-crowned Night-Heron ( N yc ticorax, nyc t ico rjx ) ,Chinese Pond Heron(A rdso Ie bacchus), Cattle Eggret (Bubulcus ibis), Chinese Egeret (Egretta eulophots). All examined birds are young. The 20 regular blood parameters, including blood solid structure, protcin grease, blood sugar, ferment vitality.
本文报导了白鹭(Little Egret),夜鹭(Black—crowned Night—Heron),牛背鹭(Cattle Egret),池鹭(Chinese Pond Heron),黄嘴白鹭(ChineseEgret)五种鹭科幼鸟二十项血液常规指标的测定结果,其中包括血液固体结构、蛋白质.
3.A 261 bp sequence of the bovine MyoD gene intron 2 was cloned and was found to bear no similarities to the human MyoD gene sequence. Polymorphisms of the Myod gene in cattle including three Chinese breeds(Luxi cattle,Jinnan cattle and Qinchuan cattle) and four cross-breeding populations(Limousin × Luxi cattle,Simmental × Luxi cattle,Charolais × Luxi cattle and Angus × Luxi cattle) were detected by PCR-SSCP.
用PCR技术克隆到MyoD基因的第二内含子,采用PCR-SSCP方法研究了3个黄牛品种(鲁西牛、晋喃牛、秦川牛)及4个杂交肉牛(夏洛莱×鲁西牛、安格斯×鲁西牛、利木赞×鲁西牛、西门塔尔×鲁西牛)群体MyoD基因的多态性,并分析了基因位点多态性与肉牛肉质性状的相关性。
4.Directed on the present situation and existing problems in boosting beef cattle industry based on the yellow cattle improvement in China, the review indicated that several relationships, such as integration of individual households and large scale cattle farms, integration of yellow cattle improvement, crossbreeding, breed conservation and utilization, integration of high grain diet intensified fattening and low grain diet economic fattening, should be handled properly; and the requirements of profitable cattle industry for increasing reproductive survive rate, using hybrid vigor and improving the weight gain, the main factors affecting economic return of large scale cattle farms and the technology level improvement in cattle industry were duiscussed as well.
本文就近来我国以黄牛改良为特点的肉牛业蓬勃发展现状与存在问题，指出应处理好养牛经营形式千家万户与规模牛场相结合、黄牛肉用与肉役兼用相结合、黄牛改良选育与杂交、保种及利用相结合、高精料强度肥育与低精料适度育肥相结合等几个问题；并就提高养牛经济效益对提高繁殖成活率、充分利用杂种优势、提高日增重的要求和影响规模牛场经济效益的主要因素及如何提高养牛科技水平等问题提出探讨。
5.In this research, five Chinese yellow cattle breeds, which were En-shi cattle, Qin-chuan cattle, Wan-nan cattle, Wenling-Gaofeng cattle and Yan-bian cattle were studied for the molecular genetic diversity in MHC-DQB*exon2, DRB3*exon2 and their upstream regulatory region by DNA sequencing.
本研究采用测序法，分别对恩施黄牛、秦川牛、皖南牛、温岭高峰牛、延边牛的MHC-Ⅱ类基因DQB和DRB_3及其上游调控区序列进行分析，以揭示中国黄牛MHC基因的分子遗传多样性，得到以下结果：
6.1. 127 DQB*exon2 alleles were found in Chinese yellow cattle. The number of alleles was 36, 42, 35, 40 and 42 respectively in En-shi cattle, Qin-chuan cattle, Wan-nan cattle, Wenling-Gaofeng cattle and Yan-bian cattle.
(1) 本研究在中国黄牛中共发现127种DQB~*exon2等位基因，恩施黄牛中36个，秦川牛中42个，皖南牛中35个，温岭高峰牛中40个，延边牛中42个。
8.Normal and health cattle including Qinchuan cattle 531 and other cattle( Nanyang cattle, Holstein, Charolais, Limousin, Piemontese, Simmental, Gelbrieh) 512 were measured body traits, appearance estimation and angles of linear assessment in this study, which and 12 kinds of body Indexes were applied to systematically explore the regulation of growth and development characteristics of cattle figure using multi-statistical analysis.
本试验选取健康无病的不同年龄秦川牛531头，其它品种牛(南阳牛、荷斯坦牛、夏洛来牛、利木赞牛、皮埃蒙特牛、西门塔尔牛和德国黄牛)512头，对各品种牛进行体尺数据测量、外貌鉴定评分，并估测线性评分的角度。
9.259 DRB3*exon2 alleles were found in Chinese yellow cattle. The number of alleles was 67, 72, 64, and 77 respectively in Qin-chuan cattle, Wan-nan cattle, Wenling-Gaofeng cattle and Yan-bian cattle.
发现了259种DRB_3~*exon2等位基因，秦川牛中67个，皖南牛中72个，温岭高峰牛中64个，延边牛中77个。
10.respectively. In this study, PCR-RFLP was applied to analyze the polymorphism of LPL gene in 262 cattle that comprised of seven bovine breeds, namely Angus, Hereford, Chinese simmental、Luxi cattle、Qinchuan cattle, Jinnan cattle、 simmental×Mongolia cattle.
本项研究利用PCR-RFLP技术对安格斯牛、海福特牛、中国西门塔尔牛、鲁西牛、秦川牛、晋南牛和西门塔尔×蒙古牛杂交牛7个品种的262头个体LPL 基因进行多态性分析。
