本研究对初生、２１、２８、３０、６０、９０、１２０、１５０、１８０日龄和１２月龄等不同阶段中国白兔的增重、成活率和繁殖性能进行测定，结果如下：窝均产仔８．０７只，初生产４９．１６克，２８日龄断奶产２８５．９６克，断奶成活率９４．９２％；９０日龄产９７１．１０克，成活率８２．２２％；１８０日龄产１７３２．７８克，成活率９１．２２％；成年体重２２７３．３３克。结果显示：中国白兔成年体重小，生长速度较慢，但繁殖能力强，成活率高     

我国黑荆树适生区的划分及各区栽培技术要点

Based on the distribution of 64 locations in wattle natural distribution in Australia and the data collected from 61 plantations in 30 more countries, 5 important factors were selected for determining the suitable climatic requirements for the growth of wattle. The experience of plantation wattle in China for over 30 years has been summarized. According to the comparison of climate and geographic distribution of wattle in China and other countries, China is a suitable country for growing wattle. Based on the results of our investigation, a division of suitable areas for growing wattle in China was made. Key points of planting method in each area were suggested.     

Mapping B-cell linear epitopes of NS3 protein of bovine viral diarrhea virus

Bovine viral diarrhea virus (BVDV) is a member of the genus Pestivirus within the family Flaviviridae. NS3 is one of the immunodominance regions of the BVDV viral proteins. To identify the potential B-cell linear antigenic epitopes within BVDV NS3 region, serial overlapping truncations covering the whole region were expressed and purified, and screened by multistep of Western-blot. We found (₁VCKKITEHERCHVNI₁₅), (₂₀AFFGVMPRGTTPRAPVR₃₆), (₄₆RRGLETGWAYTHQGGI₆₁), (₂₈₁EGDMATGITYASYGYFC₂₉₇), (₄₂₆YSGEDPANLRVVTSQSPYVVVATNAIESGV₄₅₅) and (₄₈₁FIVTGLKRMAVTVGEQA₄₉₇) can be recognized by the BVDV infected bovine serum. These proteins have been confirmed by indirect enzyme-linked immunosorbent assay (I-ELISA). The results of this study might open new perspectives on the structure and antibody–antigen reaction of the non-structural proteins and may aid in the clinical application as well.     

解读涉牧违法行为涉嫌犯罪的主要罪名

畜牧兽医部门执法人员在行政执法过程中对涉牧违法行为是否涉嫌犯罪和涉嫌何种犯罪的把握,是能否依法、及时向刑事司法机关移送案件、加大对涉牧违法犯罪的打击力度的关键因素。本文依据《中华人民共和国刑法》、相关司法解释和相关法律法规,对畜牧兽医部门在行政执法过程中可能遇到的涉嫌犯罪案件3大类12个主要罪名进行了归纳和解读,可为畜牧兽医行政执法更好地与刑事司法衔接提供参考。     

植酸酶在畜禽生产中的应用研究

植酸又名肌醇六磷酸,是一种抗营养因子。植酸在低pH条件下可与蛋白质分子的碱性基团结合,络合蛋白质,抑制胃蛋白酶、淀粉酶和胰蛋白酶等消化酶的活性,降低蛋白质、淀粉及脂类等营养成分的消化利用率。同时,植酸也具有极强的螯合能力,能与钙、钾、锌、铁及铜等矿物质形成不溶性盐类,影响矿物质的吸收。

泰王为爱犬两次著书

由泰国国王普密蓬亲自编写的再版新书《通丹的故事》在短短一周内就创下了50万本的销量，成为泰国8年来最畅销的书。就连佛教徒都认为，此书“可以扩大爱的范围，并且照亮人心”。     

麻江县香麦栽培与利用调查初报

通过对麻江县种植历史较长、面积较宽的牧用香麦进行资源调查和主要的生物学观测分析,表明其具有遗传性状稳定、冬季产草量高、适口性好、可自留种等特点,并初步检索为植物学分类上的禾本科燕麦属,可在海拔580~1 000 m的区域种植。这对于我省开发和引进新的牧草品种具有较高的参考价值。     

Cloning, expression and characterization of monkey (Macaca fascicularis) CD137

CD137 plays an important role as a co-stimulatory molecule in activated T cells. Agonistic CD137 specific antibodies have been investigated as therapeutic agents to promote tumor-specific immune responses by direct activation of T cells. As part of the pre-clinical pharmacological evaluation of cynomolgus monkeys, monkey CD137 was cloned and characterized. The deduced amino acid sequence encoded a full-length gene of 254 amino acids 95% identical to human CD137. Sequence variants identified in monkey CD137 include four splice variants lacking the transmembrane domain. These variants were detectable in human including two previously unreported variants. Two missense single nucleotide polymorphisms were detected present in 42 and 50% of 36 monkeys tested. In both monkey and human, mRNA expression of full-length CD137 and splice variants were significantly increased in peripheral blood mononuclear cells (PBMCs) upon stimulation by anti-CD3 antibodies. Recombinant monkey CD137 protein was bound with high affinity by an agonistic anti-human CD137 antibody but not by an anti-mouse CD137 antibody. In summary, compared to human, monkey CD137 showed distinct extracellular domain amino acid sequence and sequence polymorphisms. Thus, antibodies directed against epitopes in this extracellular domain could have differences in pharmacologic activity between cynomolgus monkeys and human or across individual cynomolgus monkeys.     

欧盟皮内变态反应比较试验法结合ELISA检测牛结核病的研究

现在应用较多的牛结核病检疫方法有变态反应、ELISA等方法。检疫牛结核病目前OIE唯一指定方法是皮内变态反应,该方法也是最古老的方法之一,经过多次改进,仍然为各国所用。该方法的不足是非特异性反应过高,且只能检测细胞免疫状态。牛结核
