Evaluation of reference genes for gene expression studies in pig muscle tissue by real-time PCR
gene stability reference genes quantitative PCR Sus scrofa age categories of pigs muscle tissue
2015/6/9
The selection of reference genes is essential for gene expression studies when using a real-time quantitative polymerase chain reaction (PCR). Reference gene selection should be performed for each exp...
The aim of this study is to reveal the morphology of the lyssa in the cat and dog. Eight heads of adult healthy cats and eight heads of dogs of both sexes were used as materials. In the cat the lyssa,...

家猪减数分裂粗线期二价体与有丝分裂中期染色体的比较研究Comparative Studies on Meiosis Pachytene Bivalents and MitosisCMetaphase Chromosomes of Pig (Sus scrofa domestica)
家猪 二价体 有丝分裂染色体 染色粒结构带 G-带
2008/1/30
摘要以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例, 比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹...
摘要应用常规方法获得了杂种猪( 野猪（♂）×家猪（♀）)的核型、C带和174条带纹的G带，应用微量秋水仙素法得到了258条带纹的高分辨G带。结果表明，杂种猪的二倍体细胞染色体数目2n=38，C带具有多态性，G带和高分辨G带与家猪相比无明显差异，它们属于同一种。

含不同比例莱芜猪血缘杂交猪胴体品质及肉质特性的研究Studies on Carcass and Meat Quality Performance of Crossbred Pigs withGraded Proportions of Laiwu Black Genes
猪 莱芜猪 杂交 胴体品质 肉质特性
2008/1/6
摘 要： 以莱芜猪、3/4莱芜猪、1/2莱芜猪、1/4莱芜猪和大约克夏猪（共60头）为研究对象，在同样条件下饲养至90kg屠宰，研究比较不同比例莱芜猪血缘对肥育猪胴体品质和肉质特性的影响。结果表明：不同血缘结构的试验猪间在胴体重、胴体长、后腿比例和背膘厚方面存在显著的差异（P<0.05）；眼肌面积和瘦肉率方面则存在极显著的差异（P<0.01），并且是随莱芜猪血缘含量的减少，其胴体长、后腿比例、眼肌...
仙居鸡染色体Ag-NORs及其与生产性能的关系Studies of Chromosome Ag-NORs of Xianju Chickens and the Relation with the Productive Performance
染色体 Ag-NORs 生产性能
2007/12/31
摘要采用外周血淋巴细胞培养，对仙居鸡Ag-NORs进行了研究。结果表明：仙居鸡的Ag-NORs常定位于1p、3p、4p、Zp、2q上，均数为3.26，众数为3，不同个体间以及同一个体不同细胞间Ag-NORs的大小，数目和分布存在多态性，研究还发现有Ag-NORs联合现象。此外，Ag-NORs频率不同的两组间生产性能差异比较表明：公鸡的胫骨长差异显著（P＜0.05），其它两组间的生产性能差异均不显著...
摘要采用外周血淋巴细胞培养--空气干燥法，对泰和乌骨鸡染色体核型和带型进行了研究。结果表明：泰和乌骨鸡体细胞染色体数目2n=78,染色体基本臂数AF=90，1、9号染色体及Z、W性染色体为中央着丝粒（m）染色体，2、4、7号染色体为亚中央着丝粒（sm）染色体，3、6、8、10号染色体为端着丝粒（t）染色体。G带研究表明：前10对大型染色体可分为29个区，190条带。C带处理发现，所有母鸡分裂相中W...
