为了解保定市兽医社会化服务机构建设现状,完善兽医社会化公共服务职能,通过深入辖区内动物诊疗机构、规模养殖场、大专院校等单位进行调研,梳理了保定市在兽医公益性服务、兽医经营性服务等兽医社会化服务体系发展的概况。认为应通过全面加强公共服务体系建设,引导兽医社会化服务力量发展等措施,积极推进社会化服务体系建设;指出保定市面临公益性服务经费和保障力度不足、畜牧生产一线难以吸引年轻力量、执业兽医脱离畜牧生产一线严重的发展难题;为此提出了做好顶层设计、寻求有关部门与大型企业集团的有机结合、完善人才选用机制、提高乡村兽医服务能力等发展建议。 相似文献

兽医社会化服务是兽医服务的一项重要内容。近年来,广西壮族自治区坚持问题导向,创新工作思维,大力发展兽医社会化服务,强化技术服务支撑,构建了多层次、多样化的兽医社会化服务模式。通过政策先导、整县推进的方式以及列明服务清单、培育服务主体、强化服务组织考核等手段,解决了兽医社会化服务发展中配套政策不健全、推动实施难、服务业态单一、服务监督评价难、基层防疫队伍管理难等问题,使基层动物防疫队伍结构得到优化,兽医服务专业化水平、免疫效率和质量、防疫人员待遇、动物防疫监管实效进一步提升,激励了更多的社会力量参与到兽医社会化服务中。但仍存在基层推动兽医社会化服务工作意识不强、兽医社会化服务组织发展缺乏后劲、财政投入不足等问题。建议继续加强宣传引导,培育新的市场主体,强化顶层设计和政策扶持,以适应新形势下畜牧业发展的需要。本文通过总结当地兽医社会化服务实践中的一些经验做法,以期为各地兽医社会化服务发展提供参考。 相似文献

加快推进基层兽医社会化服务发展,创新政府公共服务供给模式,是提高兽医公共服务水平和效率的有效途径。湖南省浏阳市主动引入和培育社会组织,挖掘社会力量,以政府引导与社会参与相结合的路径,探索"政府引导、社会参与、项目服务、企业运作"实践新模式。通过兽医社会服务组织参与政府购买服务实践,将原来政府提供的兽医公共服务通过购买服务的方式交由专业性社会组织来提供,理顺了政府与社会关系,优化了疫病防控结构,满足了社会需求,拓展了基层兽医组织发展空间。同时提出要加大社会组织培育,明确公共服务范围,强化市场化运作机制,规范合同管理的发展建议。 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

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

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
