畜产品质量安全与否已经成为消费者日益关心的敏感问题,也成为制约畜产品出口创汇的“瓶颈”。特别是近年来,随着人们健康保健意识的增强,消费观念发生了根本性的改变,市场上一些无污染、无公害、绿色畜产品越来越受到人们的青睐和欢迎。因此,为了人类的健康和生态环境的和谐发展,发展绿色畜牧业,打造“绿色畜产品”,让无污染、无残留、无公害的绿色畜产品成为市场的主打产品, 相似文献

1“狼”真的来了
近年来,我国渔业发展突飞猛进,产量连年攀升,连续15年位居世界第一。生产的发展,水产品价格的放开,活跃了水产品市场,丰富了城乡居民的“菜篮子”。但是,我们也应该看到,我国渔业发展至今仍是以量的增长为主,粗放经营,低价、同质化竞争严重,产业低度化成为制约水产业提高国际竞争力的关键,中高档产品少而“大路货”多,鲜有国际知名品牌,就连在中央及省市电视台做过广告的也属凤毛麟角。长此以往,我国渔业发展的后劲何在,产业的出路何在?在我国水产品已由卖方市场过渡为买方市场,在渔业市场化程度越来越高的条件下,水产品的市场竞争愈演愈烈,价格已不再是最主要的竞争手段。随着渔业产业化进程的进一步加快,质量、品牌、市场之间的相互关系将更加紧密,靠质量创名牌,靠名牌拓市场,靠市场争效益的趋势将日益明显。 相似文献

近年来,世界各地疯牛病、口蹄疫、禽流感等烈性动物疫病此起彼伏,接连不断,给一些国家和地区的畜牧业发展和畜产品出口贸易造成重大的经济损失,甚至影响政局的稳定,成为一种“政治经济病”。我国虽然近年来对动物防疫工作日益重视,加大了对动物防疫工作的资金投入和技术投入,动物防疫水平有了较明显的提高,但是,随着我国加入世贸组织后,畜产品将参与国际市场的竞争,动物疫病成为制约我国畜产品进入国际市场和在国际市场参与竞争的主要因素。因此,提高对动物防疫工作重要性的认识,全面加强动物防疫工作,确保畜产品的安全已迫在眉睫、刻不容缓。 相似文献

近几年来,随着人们对安全、卫生、健康、生态和环保等问题的日益关注,追求无污染、无残留产品的绿色意识已深入人心。我国已加入WTO,国内和国际市场的竞争日益激烈,在这严峻的挑战面前,我国畜牧工作者作出了“发展绿色环保畜牧业”的抉择。追求“洁净畜牧业”,生产“绿色畜产品”已成为共识。在此背景下,绿色生物饲料应运而生了。 相似文献

进入新世纪以来,我国畜牧业面临日益严峻的挑战.一方面,国内市场许多畜禽产品都出现了"卖难"问题;另一方面,国际市场由于发达国家日益严格的"绿色"壁垒的限制,出口也受到了极大制约.这种局面的形成,是产量增加、结构不合理、消费制约、进口冲击以及贸易壁垒等因素综合作用的结果.从深层次分析,是与我国畜产品生产标准化程度不够有很大关系的.由于涉及食品特别是动物性食品安全质量的事件此起彼伏,消费者要求食品安全的呼声越来越高,农业部决定从今年起在全国范围内实施"无公害食品行动计划",因此,加强畜牧业标准化体系建设,实现标准化生产,不仅是发展无公害畜产品的必然选择,也是我国畜牧业在新的历史时期取得新突破适应入世形势的重要举措. 相似文献

入世以来,我国肉类出口频频受阻,主要障碍来自进口国针对安全卫生质量构筑的“绿色壁垒”。随着世界各国特别是发达国家对食品安全卫生质量的要求日益严格,进口门槛不断加高,我国肉类怎样才能更多进入国际市场,在激烈的国际市场竞争中立于不败之地,是各级政府、有关部门特别是出口肉类生产企业必须高度关注的一件大事。我国是肉类生产大国,肉类是我国重要的出口产品。我国入世后,虽然肉类进入国际市场的门开得更大了,但是,门槛却更高了,特别是“绿色壁垒”的门槛越来越高。入世以来,我国肉类出口频频受阻,主要障碍来自进口国家针对肉类安全… 相似文献

近年来,我国及周边地区高致病性禽流感等人畜共患传染病频频发生,不仅严重威胁畜牧业持续健康发展,还严重危害人民群众身体健康和生命安全,动物防疫工作的重要性、迫切性日益显现。我国虽然近年来对动物防疫工作日益重视,加大了对动物防疫工作的资金和技术投入,防疫工作水平有了较大提升,但是动物疫病仍是制约我国畜产品进入国际市场的主要因素之一。因此,重新认识和加强动物防疫工作,确保畜产品的安全已迫在眉睫、刻不容缓。 相似文献

对畜产品安全生产的几点思考 总被引:1,自引:0,他引:1
近几年来,国际上相继发生牲畜口蹄疫、疯牛病、二日恶英、禽流感事件,国内相继发生“瘦肉精”、“苏丹红”事件及亚洲Ⅰ型口蹄疫、禽流感、人感染猪链球菌病、高致病性猪蓝耳病、兽药残留等问题,这些问题的发生已对畜产品消费和国际贸易产生了很大的负面影响,受到各国政府和广大消费者的密切关注。特别是我国加入WTO后,国际市场门槛的抬高,绿色壁垒已成为制约畜产品出口创汇的“瓶颈”。 相似文献

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。 相似文献

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. 相似文献

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. 相似文献
