动物检疫是把好畜产品质量安全的源头,是百姓食肉安全的关键环节,按照《动物防疫法》及农业部有关规程的规定,动物出栏前应向当地县级以上动物卫生监督机构申报检疫,动物卫生监督机构收到检疫申报后,根据情况给予受理或不受理,受理的派官方兽医到场到户或指定地点,对出栏动物进行检疫,称之为产地检疫.经官方兽医产地检疫合格的动物,凭动物卫生监督机构出具的《动物检疫合格证明》(证明上有官方兽医签名)方可出栏、调运和交易,为避免经产地检疫的动物与检疫证明不符,检疫证明上还专门填写了经检疫合格的动物所佩戴的耳标号码,以及该批动物的起运地点、目的地和检疫证明有效期等. 相似文献

随着我国社会经济的发展和人民生活水平的提高,动物卫生监督工作越来越受到各级政府和广大人民群众的关注。多年来,各级动物卫生监督机构严格执行动物防疫法.深入开展动物检疫和监督执法工作,对检疫合格进入市场流通的动物及产品出具动物检疫合格证明,促进了动物及产品的流通,保护了人民群众的身体健康。动物检疫合格证明是动物及产品没有动物疫病的法定凭证,在全国加强食品安全监管的新形势下,加强对动物检疫合格证明的监管极为重要。 相似文献

动物检疫证章标志是动物卫生监督机构对经检疫合格的动物及动物产品出具的法律凭证和标识,是国家管理动物防疫工作的一项重要制度,也是动物卫生监督机构及其工作人员职责与法律责任之根本所在。不断规范动物检疫证章标志管理,对维护广大农牧民群众生命财产,维护社会公共卫生安全,维护动物卫生监督工作秩序,保护持证人合法权益发挥着重要作用。 相似文献

检疫证明回收是屠宰厂(或肉类联合加工厂)在屠宰动物前核对《动物产地检疫合格证明》或《出县境动物检疫合格证明》和《运载工具消毒证明》,具备有效检疫合格证明的动物准许入厂屠宰并回收检疫证明。同时也是动物防疫监督机构促进检疫工作和逆向监督的重要措施。 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

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

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

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
