论临潭县放牧牛羊舍饲育肥产业化发展的思路和方法

临潭县位于甘肃省南部,处青藏高原与黄土高原的结合部,农牧交错地带,是国家、甘肃省扶贫开发重点县。临潭县以高原农业为主,牧业产值仅占农业总产值的45%左右,合理利用天然草原,开发人工草地,发展草食畜牧业,借以提高农民收入,逐步形成以牧促农的发展格局,调整农业产业结构已追在眉睫。文章从分析临潭县发展牦牛、藏羊育肥产业的有利条件出发,结合当地牛羊产业化发展的现状和存在的主要问题,提出以育肥1.5～2.5岁的牦牛或羔羊为主,生产高档牛羊肉;研究饲养管理模式,提高效益;建立牲畜交易市场,完善流通渠道;制定优惠政策,吸引企业或个人投资,培育龙头企业及创"高原绿色"食品品牌,开拓高档牛羊肉市场等发展思路和方法。     

临潭县羊产业扶贫发展现状及对策

临潭县是国家扶贫开发重点县,是甘肃省深度贫困县。近年来,临潭县将羊产业作为重点扶贫产业来抓,带动贫困农户脱贫致富。本文对临潭县羊产业的发展现状、优势、产业布局及扶持原则、扶持方式作了详细介绍,并对今后羊产业的发展提出了一些建议,以供参考。

为了进一步了解临潭县、永靖县、华池县、榆中县等地区羊泰勒虫病病原感染情况,对这4个地区的病羊开展了血液涂片染色镜检和羊泰勒虫PCR检测。结果表明:永靖县、榆中县、临潭县的羊泰勒虫病是吕氏泰勒虫和尤氏泰勒虫的混合感染,而华池县羊泰勒虫病是单一的尤氏泰勒虫感染,证实了临床怀疑诊断。     

辛硫磷乳油和林丹乳油刷洗羊体驱杀青海血蜱的试验

羊泰勒焦虫病在甘南州分布面广,危害严重,给养羊业带来很大损失。近几年来,我们使用化学药物治疗和预防,效果不太理想。青海血蜱是羊泰勒焦虫病的传播者,为了阻断传播媒介的侵袭,减少羊泰勒焦虫病的发生,我们于1985年3月至5月在临潭县羊沙乡做了用辛硫磷乳油和林丹乳油分别刷洗羊体驱杀青海血蜱的试验。一、材料和方法: 1.药品:50%辛硫磷乳油,天津农药厂生产;20%林丹乳油,内蒙古牙克石兽药厂生产。 2.试验羊:临潭县羊沙乡新庄、八达等九个自然村的有少量蜱叮咬的绵、山羊760只,重点观察173只,其中成年羊104只,羔羊69只,分成:辛硫磷乳油组(成年羊56只、羔羊20只),林丹乳油组(成年     

临潭县三年控制猪瘟、鸡新城疫

临潭县位于甘南藏族自治州东部,辖19个乡,540个自然村,养猪养鸡在畜牧业生产中占有重要地位。为了有效地控制猪瘟、鸡新城疫,保证牧业生产的发展,1984年在州畜牧局的主持下,我站与州畜牧兽医站签定了”三年控制,五年消灭猪瘟、鸡新城疫的意见”的协议书。经过三年不懈的努力,基本上控制了猪瘟、鸡新城疫。现将具体做法介绍如下:

商会自治的基石——商会自治规范研究

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。

Comparison of 2 methods of centesis of the bursa of the biceps brachii tendon of horses

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air.

乳酸杆菌益生作用机制的研究进展

乳酸杆菌作为益生菌广泛用于人和动物。本文综述了乳酸杆菌改善宿主健康的机制。乳酸杆菌可通过产生抗菌物质如乳酸、过氧化氢、细菌素,或者通过竞争营养或肠道黏附位点来抑制致病菌;通过诱导黏附素的分泌或阻止细胞凋亡而增强肠道的屏障功能,从而保护肠道。文章重点讨论了乳酸杆菌表面成分（表面蛋白、脂磷壁酸和肽聚糖）与肠道受体（Ｃ型凝集素受体、Ｔｏｌｌ样受体和 Ｎｏｄ样受体）,阐述了他们结合后启动免疫调节信号,调控肠道免疫功能以发挥改善健康作用的机制。     

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF

Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo.
