壳聚糖对乳房炎奶牛血清胆固醇、尿酸和肌酐的影响 总被引：4，自引：0，他引：4
为确定壳聚糖对奶牛乳房炎的治疗效果,选择产奶量、胎次和泌乳期相近,营养中等,乳房炎阴性奶牛6头,阳性30头,组成0(阴性对照组)、1(阳性对照组)和2、3、4、5组(试验组),每组6头.各组基础日粮和饲养管理相同.分别在基础日粮中添加壳聚糖0g、0g、10g、20g、40g和80g/d/头.连续喂养2周,分别与试验的0d、7d、14d采取血样,分离血清,测定血清中胆固醇、尿酸和肌酐的含量.结果:应用壳聚糖7～14d后,2、3、4、5组奶牛血清胆固醇含量均数有随壳聚糖用量的增加而降低的趋势,但差异不显著(P﹥0.05);血清尿酸和肌酐水平显著(P﹤0.05)或极显著(P﹤0.01)地降低.结论:壳聚糖具有加快乳房炎患牛机体对尿酸和肌酐排泄的功能,提高机体对炎症的抵抗力,促进机体的康复过程. 相似文献

在全群奶牛进行乳房炎和酮病检验之后,选择16例健康牛和12例隐性乳房炎牛,进行牛毛微量元素的测定。结果健康奶牛牛毛Fe、Cu、Zn、Ca、Pb、As和Se的含量分别是76.52±24.22,9.15±1.90,162.22±55.16,1563.4±520.7,0.986±1.349,0.284±0.236和0.296±0.116ug/g;而患牛分别为59.35±23.94,6.50±3.40,96.83±19.21,747.1±674.1,1.260±1.248,0.425±0.216,和0.326±0.092ug/g。发现隐性乳房炎牛毛中Zn、Ca和Cu的含量显著低于健康牛;而毛中Fe、Pb、As和Se的含量元显著差异。初步认为隐性乳房炎与牛毛中Zn、Ca和Cu的缺乏有关。 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献
