10种中药对奶牛乳房炎病原菌的体外抑菌试验

测定了黄芩、黄柏、黄连、大黄、金银花、秦皮、板蓝根、丹参、诃子、石榴皮对6种奶牛乳房炎病原菌的体外抑茵效果和最低抑菌浓度。结果表明,黄芩、黄柏、黄连、丹参、石榴皮对6种奶牛乳房炎病原菌均有明显的抑菌作用,其余的则差异较大；对绵阳市奶牛乳房炎的防治,首选中药为黄连,同时可选用大黄、诃子、石榴皮、黄芩、金银花组方。     

壳聚糖免疫与抗菌功能及其在防治奶牛乳房炎中的应用前景(综述)

本文描述了壳聚糖的基本特性与作用,综述了壳聚糖的免疫活性及其抗菌功能,探讨了壳聚糖在防治奶牛乳房炎中的应用前景,为提高奶牛健康水平和牛场的社会经济效益提供参考资料.     

壳聚糖对乳房炎奶牛血清胆固醇、尿酸和肌酐的影响

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.     

急性乳房炎的早期干预及护理

目的探讨急性乳房炎的早期干预及护理要点。方法随机选择在我院建卡分娩的产妇80例,对其进行早期干预和护理。结果75例产妇未发生乳房炎,1周后出院;5例急性乳房炎早期患者经过精心护理恢复健康,未发现并发症和后遗症。结论通过急性乳房炎的早期干预及护理,可有效阻止乳腺炎的发生和进一步发展,提高护理质量。     

牛毛微量元素与隐性乳房炎

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。

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
