甘肃庄浪-静宁铁矿床地质特征浅析

甘肃庄浪-静宁铁矿床位于甘肃省东部山地与黄土高原的过渡地带，大地构造属于祁连造山带东部，本文通过系统阐述矿区地质和矿床地质特征，对矿床的成因进行了初步的探讨，认为该矿床主要受区域基性岩体和断裂构造联合控制，属于晚期岩浆结晶分异形成的岩浆分结矿床。最后给出了矿床的找矿标，指明了找矿方向。     

Effect of Lysine Supplement on the Digestion and Metabolism of the Rumen in Small-tail Han Sheep

5 male Small-tail Han sheep with the body weight of 45 kg at 1.5 years old,fitted with permanent rumen fistula,to study of the effect of the supplement of the untreated commercial lysine on the rumen microbiocoenosis,rumen metabolism and whole body metabolism by 5×5 Latin square design (5 groups:control,control with low urea (equal nitrogen),low lysine,control with high urea (equal nitrogen),high lysine).The amounts of lysine-HCl supplement were 0,4.0 and 8.0 g/kg diet (as DM basis) in each group respectively,with two urea supplement control groups of equal amount of nitrogen.The results showed that by supplement of 4.0 and 8.0 g/kg of lysine-HCl diet (as DM basis) respectively,the voluntary intake of dry matter of sheep were increased by 5.5%(P>0.05) and 11.8%(P<0.05) respectively.The total amount of rumen bacteria were increased by 18.9%(P<0.01) and 23.9%(P<0.01) respectively,as the amount of rumen Coccus was increased by 21.2%(P<0.01) and 30.1%(P<0.01) respectively.The amount of rumen big Bacillus was decreased by 16.7%(P<0.05) and 33.3%(P<0.01) respectively.The total VFA of was increased by 9.6%(P<0.05) and 12.2%(P<0.01) respectively,as the butyric acid was increased by 12.8%(P>0.05) and 20.2%(P<0.01) respectively.The apparent digestibility of organic matter was increased by 6.4%(P>0.05) and 10.0%(P<0.05) respectively,the apparent digestibility of crude protein was increased by 7.0%(P>0.05) and 18.3%(P<0.01) respectively;And nitrogen retention was increased by 46.4%(P>0.05) and 110.7%(P<0.01) respectively.However,there was no effect of lysine supplement on the amounts of the rumen protozoa and fungi,and the concentration of rumen ammonia nitrogen.It was concluded that the supplement of untreated commercial lysine to adult sheep would increase the voluntary intake,digestibility,nitrogen retention the rumen microbiocoenosis and the total amount of rumen bacteria,especially the rumen Coccus of adult sheep.The effect of lysine supplement could not be replaced by urea supplement completely.

不输液治疗犬细小病毒性肠炎技术

细小病毒作为犬的一种常见病，有非常多的治疗方案，很多的方案都强调静脉输液防治酸中毒，维持正常的生理代谢直至产生抗体，期间禁水禁食。但是由于生活和工作节奏的加快，很多的畜主没有时间和精力坚持1h/次、2次/d、7~10d给犬输液。     

哺乳期和断乳期仔猪的饲养管理

仔猪可分为哺乳和断乳两个时期。在这两个时期应根据仔猪生长迅速、物质代谢旺盛和饲料利用率高的生理特点，加强饲养管理，从而为培育优良后备种猪和生长育肥猪打下良好基础。     

应用钙制剂治疗母牛瘫痪

母畜产前产后瘫痪是由钙代谢调节障碍引起的一种常见产科疾病。多见于饲养良好的壮年母牛和高产奶牛等。如果不及时治疗，将有50～60％的发病母牛在短时间内多匕亡或致残。严重影响了养牛业的发展。     

肾结石患者饮食六戒

<正>1.控制蛋白质的摄入量。蛋白质的主要成分是氨基酸,而氨基酸经过人体肝脏代谢后,可产生大量的氨。过量的氨进入人的血液后,可导致人体尿酸的增高,甚至可引起高尿酸血症。而尿酸的增高是引起肾结石的重要因素。因此,肾结石患者应将每天高蛋白食物的摄入量控制在180克以内。含有高蛋白的食物主要包括豆制品、鸡肉和鱼肉等。     

野生动物铁缺乏症

铁是毛皮动物体内的重要微量元素之一,各种动物体内含铁约30～70mg/kg,平均40mg/kg。随动物种类、年龄、性别、健康状况和营养状况不同,体内含量变化大。主要存在于血红蛋白、肌红蛋白、细胞     

指甲揭示的健康状况

指甲的生长情况和形态,随时都会受机体变化的影响。平时只要注意观察指甲形色的微妙变化,即可知道一个人的健康状况。如果出现下列病态指甲,则说明健康已经出现问题,应予以注意。指甲脆、裂首先应查明病     

“气相色谱-质谱联用技术”在药物分析研究中的应用

"气相色谱-质谱联用技术"是以气相色谱为分离装置,以质谱为检测装置通过接口技术连接后而成的一种新型的仪器分析技术。随着精准医药学、生命科学和药物分析学科的发展,色谱联用技术对药物的检测分析逐渐在疾病诊断治疗过程控制中凸显出更加重要的作用,在应用上已从小分子、热稳定、易挥发药物的分析,逐渐向生物标记物分析、药物分析等方向发展。目前,该技术已广泛应用于兴奋剂检测、药物代谢动力学、方剂学及代谢组学等领域。
