湘猪价格为何节节飚升?

8月份，我省生猪价格在7月止改回升的基础上继续上扬。据对全省19个价格调查网点监测，8月中旬全省生猪均价为每50公斤280元，比上旬涨39％，比7月中旬上涨问．7％，自7月上旬止跌以来累计已上涨14．4％。我省生猪价格节节飚升的主要原因是：一、价格回升面广。从全省19个监测网点上报的价格来看，8月中旬有16个地方的生猪价格比7月中旬回升，回升面达842％，比7月中旬扩大了近32个百分点。二、价格回升幅度较大。全省价格回升的16个地区，平均上涨了36元，其中涨幅最高的是华容县，每50公斤涨了80元；目前价位最高的是郴州市，每50公斤325…     

发改委细解当前生猪与猪肉价格形势分析

本刊辑：国家发改委今天发布的7月份价格形势分析报告显示，7月份居民消费价格总水平小幅上升。发改委有关负责人介绍说，7月份居民消费价格同比上升3．3％，涨幅比上月扩大0.4个百分点。应该看到．7月份CPI的小幅上升主要是受临时短期因素的扰动，其变动幅度并没有超出社会预期。     

2007年7月全国养猪形势月评

1 仔猪价格普遍呈上涨态势 进入2007年7月，各地仔猪价格普遍呈现有增无减的趋势，到7月底，价格涨到28．96元／kg，比7月初上涨了19．52％。全国范围内绝大多数地区7月份仔猪价格较6月份均有所上涨。本月全国仔猪平均价格达到26．00元／kg，比上月上涨了18．56％（6月份全国仔猪平均价格为21．93元／kg）。7月份全国各地仔猪仍面临数量较缺的状况，仔猪市场普遍呈现有价无市的局面。     

禽、蛋价格前期双创新高,近期回落

江西省2004年8月畜产品及饲料市场价格走势

据对我省22个集贸市场的调查统计，8月份畜产品价格与7月份相比继续保持上涨势头，同比仍大范围大幅度增长，环比除个别产品微降外，均保持上涨势头，畜产品、家禽增长幅度较大，牛、羊肉价格再次同幅增长，饲料原料及饲料成品价格继续全面上涨，幅度平衡。     

猪肉价格上涨背后的经济学

物价上涨是2007年最大的焦点,而点燃物价上涨的则是猪肉。由于猪肉价格出现突发性上涨,影响到2007年5月份居民消费价格的指数上升到3．4％,6月份上升到4.4％,7月份上升到56％,8、9、10月份都上升6％以上,11月份同比上升了6．9％,12月份为6．4。2007年全年为4．8％,比2006年上升33个百分点。2008年一二月份分别为7．1％和8．7％。那么哪些因素导致了猪肉价格的上升,为什么猪肉价格会引发CPI指数的攀升呢,     

牧业超市

自2004年4月到2005年6月份，是我省的猪市的“牛市”，仔猪、活猪、猪肉价格不断攀升，虽然饲料粮价格也有不同程度的增长，但增长幅度低于猪市，养猪效益丰厚，成为继1997年以后，养猪业的又一个黄金时期。猪农赚了个盆满钵平。2005年7月份以后，我省猪市出现下滑，从图表可窥一斑。     

江西省2004年12月畜产品及饲料市场价格走势

据对我省22个集贸市场的调查统计，2004年12月份畜产品价格与11月份相比仍保持回落势头，同比仍大范围较大幅度增长，畜产品、家禽价格回落幅度不一，牛、羊肉价格增幅不大，饲料原料及饲料成品价格有增有减．幅度不一。     

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.
