安全畜产品生产存在的问题及对策 总被引：2，自引：0，他引：2
随着人们生活水平的提高 ,人们对畜产品的要求已经从量的满足转变为质的需求。从我国国内近几年来畜牧业的发展情况来看 ,我国畜产品总量连年增产 ,但畜产品安全问题却日益突出。轰动全国的“瘦肉精”事件的发生 ,使人们对畜产品的安全性更加重视。如何搞好优质安全畜产品生产已是当今畜牧业发展的燃眉之急。1 安全畜产品的含义安全畜产品 ,概括地说也就是“无疫病、无残留、无污染”的畜产品。要求在符合无公害畜产品产地环境评价要求的前提下 ,其有毒有害物质含量在国家法律、法规及有关强制标准规定的安全允许范围内。从养殖到餐桌实行… 相似文献

“公司 农户”是实现畜牧业产业化发展模式之一,也是农民增收的重要手段。但这种发展模式在管理机制、组织形式等存在问题,影响农户生产出来的畜产品质量,很难与大市场对接。养殖小区的目的之一就是实现“六统一”,即“统一品种、统一用料、统一用药、统一防疫、统一管理和统一销售”,提高畜产品质量,使养殖业向规模化、集约化发展。“公司 园区 农户”的组织形式克服了“公司 农户”存在着管理上的困难等先天不足,使公司与农户的联合更趋紧密,既有利于提高农民的知识技术水平,推广先进的饲养技术,也便于实行规范生产,从而达到提高产品质量,实现公司与农户利益双赢的目的。 相似文献

近几年来,随着人民生活水平的提高,肉、蛋、奶等动物食品在人们膳食中的比重不断增加,畜产品质量受到全社会的关注,餐桌健康越来越被人们所重视。然而国内外食品安全问题接连不断,危害严重,产地环境、生产过程、加工过程等是影响畜产品质量的重要因素,畜产品的安全问题直接影响人体健康和畜牧业的发展,严重影响社会安定和国民经济发展。动物饲料、动物疫病、兽药、激素残留、有毒有害的化学物质污染、动物饮水,以及饲养的周围环境等都可以影响畜产品的安全。最重要的因素首先是动物疫病,许多动物疫病可以通过动物源性食品传播给人,威胁人类的健康和生命,其次饲料、饲料添加剂和兽药的品质也是影响畜产品质量安全的重要因素。[编者按] 相似文献

畜禽养殖和畜产品流通等环节的兽药残留、动物疫病、环境污染等诸多因素,均直接或间接影响畜产品质量安全。新时期,我们应从加强畜禽养殖环节监管,建立健全动物防疫体系和畜产品可追溯体系着手,规范养殖行为,加大动物疫病防控工作力度,完善畜产品加工、运输、储存、销售等环节的监管措施,强化动物卫生监督,全力保障畜产品质量安全。 相似文献

1影响畜产品质量安全的主要因素
饲养环境不合理是影响畜产品质量安全的一个重要因素。饲养环境的影响，一方面主要为工业“三废”、农药和畜禽粪便等，这些可经呼吸、进食、饮水进入或积累在畜禽体内，造成蓄积。另一方面，许多养殖户已放弃一家一户的散养方式，开始集中饲养并达到一定规模，但是许多所谓的规模化养殖，建筑简陋，管理设施不配套；养殖密度大，没有无害化处理设施，交叉污染严重；同时饮水喂料、疫病防治、粪便排放、病死动物处理等达不到要求；养殖档案不建立，或记录不完整、不准确，达不到标准化、无公害养殖条件。 相似文献

我国畜产品质量安全状况令人担忧。笔者认为畜禽饲养环境恶劣、饲料品质不良、不规范使用兽药、非法使用违禁药品、畜禽疫病、养殖方式落后和畜产品质量检测体系不健全等是影响畜产品质量安全的主要因素。建议从养殖场选址、大力推进畜禽规模化标准化养殖、强化畜牧业投入品监管、加强认证体系建设、建立健全畜产品质量安全检测体系和提高国民畜产品质量安全意识等方面来破解畜产品质量安全问题。 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

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
