马传贫驴白细胞弱毒疫苗株跨膜蛋白主要免疫决定区基因的克隆与表达

从感染驴白细胞的马传贫驴白细胞弱毒疫苗株前病毒DNA中克隆了编码跨膜蛋白主要免疫决定区(TMIR)的基因，并在大肠杆菌中进行了表达。所表达的融合蛋白有一部分是可溶的，其氨基端带有6个组氨酸的标签，因此可以用固定化金属离子亲和层析法在非变性条件下进行纯化。在间接酶联免疫吸附试验(ELISA)和免疫印迹试验中，重组的TMIR蛋白可与马传贫阳性血清样品发生反应，而与健康马血清无任何反应。这表明该重组蛋白具有良好的抗原性和特异性，可用于马传贫弱毒疫苗株在体内外复制、接种马体内免疫应答及马传贫诊断的研究。     

波尔山羊杂交后代体尺、体重与肉用性能的相关性研究

本文利用 SPSS数据处理软件 (10 .0版 )统计分析了 2 3只 (约 8～ 9月龄 )波尔山羊与唐山奶山羊杂交后代公羊的体尺、体重和肉用性能。结果表明 :(1)波尔山羊与唐山奶山羊杂交 F1 代体尺、体重与肉用性能指标的变异程度大于 F2 代 ,其中宰前重、胴体重、净肉重和胸宽四项指标变异程度在 F1 和 F2 代中都很大 ;(2 )杂交 F1 代、F2 代各项指标 t检验结果 ,除胸宽外其余指标差异显著或极显著 ;(3 )波尔山羊杂交后代中胸宽与各项指标间相关不显著 ,宰前重、胴体重、净肉重与体尺指标相关显著或不显著。     

Organic Acids Placed into the Cloaca to Reduce Campylobacter Contamination of Broiler Skin During Defeathering

Campylobacter numbers on broiler carcasses can increase dramatically during defeathering because of leakage of contaminated gut contents in the feather-picking machine. Food-grade organic acids have been shown to be effective in killing bacteria. Placement of organic acids into the cloaca prior to defeathering was tested to determine if such a treatment could lower the number of Campylobacter that escape and contaminate broiler breast skin during automated feather removal. Campylobacter numbers on the breast skin of treated carcasses increased during defeathering but resulted in numbers that were only about 2% of those observed on control carcasses. Placement of food-grade organic acids in the cloaca of broiler carcasses may be useful as a means to lessen the impact of automated defeathering on the microbiological quality of carcasses during processing.     

近似法计量施用有机肥料对培肥水稻土土壤的研究

用近似法计量施用有机肥培肥土壤,测定土壤有机质矿化率和农肥及作物根茬的腐殖化系数。5a试验结果表明,土壤有机质矿化率在轻壤质良水型水稻土上平均为2.44%,轻壤质滞水型水稻土上平均为1.39%。有机质的腐殖化系数:马粪为35%～40%;猪粪为28%～34%;水稻根茬为45%。根据上述结果,计算了有机肥的建议施肥量,该计算值在水稻土上基本符合生产实际情况。

几种叶面肥料在小菊上的筛选与应用研究

试验采用单因素随机区组设计,叶面喷施肥料的施肥方法,应用方差分析和多重比较分析试验数据,从而筛选出小菊最佳的营养元素配方。试验从不同叶面肥料在小菊上的筛选与应用研究的试验结果得到：小菊对肥料具有较强的选择性：三高灵的施用能够增加小菊的开花数量和鲜叶片叶绿素的含量；宝力丰的施用能提高小菊单株的干物重；OPAL的施用能延长小菊开花的花期。     

高原瘦肉型猪肥育性能与胴体品质分析

选择59头高原瘦肉型猪，断奶后每个血统选用5～9头公猪为一组，经育肥达90kg体重屠宰，测定其胴体性状和胴体品质，测定结果表明全期日增重均在500g以上，但各世代有差异，其胴体品质较之互助猪有了明显提高。     

Decreased transport of orally administered protein into the blood circulation of developing juveniles of Japanese eel Anguilla japonica

ABSTRACT: To clarify the quantitative changes in the transport of orally intubated protein into the blood circulation as macromolecules in development, immunoglobulin Y (IgY) extracted from chicken eggs was administered orally to juvenile Japanese eel, Anguilla japonica . For the first experiment, which was performed before the commencement of artificial feeding, the oral delivery of 2.0 μg/0.1 g bodyweight of IgY resulted in a rapid increase in plasma IgY to a maximum of 2.30 μg/mL. However, the transport of IgY into the blood decreased significantly in the experiments that followed, which were performed after 12, 25 and 42 days. During this period, bodyweight increased approximately by a factor of eight, and rapid growth of the stomach was observed histologically. Possible contributions for the development of the alimentary canal to the diminishment of intestinal protein assimilation are discussed.
