牛羊冬季保膘育肥技术

<正> 在广大农村特别是山区,畜牧业生产水平低管理粗放,尤其在牛羊饲养中,由于冬季青绿饲料缺乏,几乎完全靠采食枯草和作物秸杆,导致在夏秋培育的膘肥体壮的牛羊,到冬春季又变成骨瘦如柴,形成夏肥、秋壮、冬瘦、春死之恶性循环,打破这种局面,实现牛羊冬季保膘增肥,不仅可大大提早牛羊出栏时间,而且更重要的是:冬季是牛羊肉消费旺李,以良好的膘情上市,就会     

《羊的常见病诊断图谱及用药指南》

本书由天津市畜牧兽医研究所丁伯良研究员等编著。作者根据多年的实践经验和科研成果，并查阅了相关新的资料编著而成。全书主要内容包括羊的常见细菌病、病毒病、寄生虫病以及内科、外科、产科等普通病。本书图文并茂，重点介绍了生产实际中经常发生的89种羊病的诊断技术与用药指南。     

春季怎样防治羊疾病

(一)急性胀气春天青草丛生,羊在放牧时会过量啃食,或在舍饲时因长期喂干草,偶喂青草,吃量过多,吃后在胃中急性发酵,产生大量气体,使羊反刍发生障碍,瘤胃迅速扩大,如抢救不及时或抢救方法不当羊会死亡.     

提高黑山羊养殖效益5法

一、优良品种杂交.用波尔山羊与黑山羊进行杂交,产生杂交一代,然后将杂交一代母本与波尔公羊杂交,产生的第二代杂种具有明显的优势:4月龄体重可达25千克～35千克.相当于本地羊的成年体重;在放牧条件下,10月龄杂种羊产肉量为12.5千克,是本地品种同龄羊的2倍.     

朝鲜蓟配方施肥技术

朝鲜蓟又称洋蓟,属菊科多年生草本植物.食用部份是花蕾的苞片,其营养丰富,每百克可食部份含蛋白质2.8克、脂肪0.2克、糖9.9克,并含有丰富的钙、铁、钠、多种维生素、菜蓟素、黄酮类化合物及天门冬酰氨等物质,这些物质能增强改善肝、肾功能,促进胆汁分泌,促进氨基酸代谢和降低胆固醇的作用.     

羊腰麻痹病不是风湿病

<正>羊的腰麻痹病是由一种指形丝状线虫幼虫,通过蚊的叮咬,将幼虫传播给羊,而寄生于羊的脑脊髓腔中,在临床上引起的以腰麻痹或后躯麻痹为主要特征的病状。本病多在秋末冬初发病。     

Expression and Bioinformatic Analysis of ADIPOQ Gene in Hanper Sheep

The aim of this study was to investigate the expression and biological characteristics of adiponectin (ADIPOQ) gene in longissimus dorsi muscle of Hanper sheep at different months of age.The ADIPOQ gene mRNA expression was detected in longissimus dorsi muscle of Hanper sheep at 3 different growth periods (1,7 and 13 months old) by Real-time quantitative PCR.The bioinformatics method was used to analyze the nucleotide and amino acid sequences of ADIPOQ gene,protein characteristics and network interaction protein.The results showed that ADIPOQ gene was expressed in longissimus dorsi muscle of Hanper sheep,which showed an increasing trend with the growth of the months age without significant difference (P>0.05).There was higher homology of ADIPOQ gene with Capra hircus (98.60%,99.00%) and Bos taurus (98.60%,87.00%) in nucleotide and amino acid sequences.The results of physical and chemical properties analysis showed that the molecular formula of ADIPOQ protein was C₁₁₇₂H₁₇₇₆N₃₁₄O₃₄₉S₅,the molecular mass was 26.00 ku,and the theoretical isoelectric point (pI) was 5.88,which suggested that the protein was acidic.The average value of ADIPOQ hydrophilic protein (GRAVY) was －0.403,which indicated that the protein was hydrophilic and didn’t belong to transmembrane protein.In addition,the signal peptide sequence was Met¹-Ala¹⁷,and the cleavage site was between Ala¹⁷ and Arg¹⁸.ADIPOQ existed collagen structure domain and C1Q conserved structure domain at position 45－101 and 101－237,respectively.The secondary structure mainly composed of random coil (66.95%).The construction of protein interaction network indicated that ADIPOQ might interact with ADIPOR1,ADIPOR2,CDH13 and LEP.The results provided a theoretical basis for further exploring the molecular biological functions of ADIPOQ gene in the process of muscle development in Hanper sheep.     

用绵羊进行性肺炎病毒实验感染山羊的研究

用绵羊进行肺炎病毒接种４只山羊３－４个月后，可观察到接毒山羊都出现了发育迟缓和消瘦现象，并有１只山羊山现了明显的临床病症。而未接毒的对照山羊则发育正常。接毒２８ｄ后，可以从接毒山羊的外周血单核细胞中分离到病毒。病理剖检发现４只接毒山羊中有１只山羊的多种器官出现了较为严重的病变，组织学检查则可看到典型的间质性肺炎、中度的脑炎和较为严重的脾炎的症变。以上的结果表明ＯＰＰＶ可以感染山羊，并对山羊有较强的     

缅甸将向朝鲜出口1万吨天然橡胶

据报道，为了增进两国的双边经济合作，缅甸将向朝鲜出口1万吨天然橡胶。这将使朝鲜成为缅甸天然橡胶的第五大客户，而前四大客户分别是中国、新加坡、马来西亚和印度。并且缅甸为了增加天然橡胶产量，计划用10年时间再种植4万公顷橡胶，此计划起始于2008年。
