<正> 1986年英国首次发现的"疯牛病"引起世界的恐慌,也敲响了食品质量安全的警钟。近年来,我国广州多次发生"瘦肉精"中毒事件。加入WTO后,我国的畜禽产品大量出口,但由于卫生、安全指标达不到进口国的要求,每年被退货、销毁、索赔的达几十个亿。特别是2002年1月31日,欧盟从我国出口的水产品、禽肉等中检出氯霉素,禁止我国近8亿美元的动物源性食品对欧盟出口,荷兰也开始销毁从我国进口的兔肉、禽肉和水产品,使我国的畜牧业、水产业遭受巨大损失。畜产品的质量安全问题已成为制约畜牧业国际竞争力提高的一个重要因素。一、导致畜产品兽药残留的原因  相似文献

影响我国肉鸡产品质量的原因及对策   总被引:1,自引:0,他引:1  
随着人民物质生活水平的提高,对肉类产品的追求已从传统的数量型转向质量型。人们不再仅仅满足于填饱肚子,无疫病、无残留、无污染、安全、营养、优质的绿色食品已成为近年来消费的亮点。特别是随着人们对禽肉消费的不断增加,对其安全、优质的要求愈来愈强。但是现阶段,由于众多的原因,使得禽肉的品质严重下降。如1993年我国出口日本的肉鸡因砷超标而被销毁;1999年5月,比利时发生了“二英”污染肉、蛋、奶事件,造成25亿欧元的直接经济损失;1996年欧盟以中国饲料中滥用药物、残留超标为由,停止进口中国的禽肉及其相关产品。由于质量的原因,不…  相似文献

英国东部农场近日发生猪瘟疫情,根据《中华人民共和国进出境动植物检疫法》规定,农业部日前发布禁令:禁止从英国进口猪及其产品。  为防止英国猪瘟传入我国,保护养猪业安全,农业部明确要求禁止直接或间接从英国输入猪及其产品,禁止邮寄和旅客携带英国猪产品及猪的胚胎、精液入境,经发现,一律做销毁处理。(新华社)我国进入对欧盟出口水产品一类国家名单  经过我国出入境检验检疫等部门长达5年的努力,欧盟终于在2000年2月2日公布2000/86/EC决议,将中国列入允许向欧盟出口水产品的一类国家名单。这意味着中国出口水产品对欧注册…  相似文献

<正>随着全球化经济一体化和贸易的国际化,动物性食品中兽药残留现象引起了人们的广泛关注。兽药残留问题严重地影响我国动物源性产品的出口,畜禽产品在一些国家、地区遭到禁运和退货的现象频频发生。1995年开始欧盟以中国动物卫生状况和产品质量安全达不到欧盟的要求,禁止从中国进口禽肉;日本市场上,在2004年我国禽肉冰鲜产品出口被日本全面封关,2005、2006年对我国禽肉严守禁令的时间里,美国、巴西、泰国等对日禽肉出口出现了较大幅度的增长。  相似文献

禽肉出口在我国农副产品出口中占有章要比重。家禽养殖及禽肉出口创造了大量的就业机会,带动了农村经济的发展,为国家创汇作出了较大贡献。据海关统计,1997年出口创汇达555亿美元。过去由于出口渠道较多,欧洲需要胸肉,日本需要腿肉,供需基本平衡,造成了国内家禽养殖业迅猛发展。但是自从1996年8月欧盟暂停中国禽肉进入欧盟市场以来,我国禽肉出口逐年下降,出口形势日趋严峻。l出日禽肉的现状11禽肉出口量逐年下降,以上海口岸为例,1997年、1998年出口量分别为444万吨、388万吨,较上年分别减少19.52%、1267%。这主要是出口渠道…  相似文献

如何从源头上控制出口畜禽养殖药物残留,是我国当前出口畜禽养殖发展所需要解决的重大课题。本文就出口畜禽药物残留的现状、影响出口畜禽药残超标的因素及养殖过程药残的控制措施等方面,作个简单综述。1出口畜禽药物残留的现状近年来,由于动物疫病、兽药、重金属等有毒有害物质超标而被一些国家退货、销毁,甚至中断贸易往来。例如1995、1996年,欧盟兽医委员会派员对我国进行了考察和评估,认为我国的兽医卫生状况达不到要求。又如2002年出口到欧盟的禽肉中检出硝基呋喃类、环丙沙星、和抗生素类药物残留,这都严重影响了我国的进出口贸易。2…  相似文献

欧盟于近日公布了2000/86/EC决议,将中国列入允许向欧盟出口水产品的一类国家名单。这意味着今后我国对欧盟注册企业生产的水产品,将被允许进入欧盟15个国家的市场。欧盟的这项决议同时取消了1997年公布的关于对中国水产品采取每批检验的规定,这标志着我国水产品在进入欧盟时,不必延时通关,被迫接受检查,耗费额外的仓储和微生物检验费用。这项突破不仅增加了我国水产品在欧洲乃至整个世界市场的竞争力,促使我国水产品多出口、多创汇,同时还为欧盟了解我国主管部门的执法水平和我国的经济发展状况,进而解决禽肉等其…  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

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

以国际标准强毒R株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离MG,并收集感染鸡所产蛋分离MG。结果表明,人工感染48小时后上、下呼吸道及肺已被全面感染,96小时气囊已被感染,120小时输卵管已能分离到MG,卵巢始终分离不到MG。人工感染鸡自144小时便能在其所产蛋中分离出MG。药物治疗能在72小时内消除感染,油乳剂苗则需24天后逐渐降低蛋内MG分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内MG,但以研制的种蛋浸泡剂药浴效果为最好。  相似文献

Fractures of the anconeal process of 5 pigs ranging in age from 4 to 8 months were studied radiographically and histologically. Clinically, animals with a fracture of the anconeal process had a "tight," restricted gait. In pigs at 4.5 months of age, a radiolucent line through the base of the anconeal process was composed of fibrocartilage, fibrous connective tissue, and hyaline cartilage. Subperiosteal proliferation of woven bone was located along the cranial surface of the olecranon, adjacent to the base of the anconeal process. In older animals, the radiolucent line through the anconeal process contained variable amounts of fibrous connective tissue and fibrocartilage. The proliferation of subperiosteal bone at the base of the anconeal process formed a "buttress callus" which retained a radiolucent area between the callus and the proximal surface of the anconeal process. The latter region of radiolucency was continuous with the transversely oriented line that traversed the base of the anconeal process.  相似文献

乳酸杆菌益生作用机制的研究进展   总被引:2,自引:0,他引:2  
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。  相似文献
