为了寻找和推进畜牧业循环经济发展的最佳模式,本文从生猪、牛羊等草食畜禽、家禽等方面分析了畜牧业循环经济发展的现状;指出了畜牧业循环经济发展中存在的问题:对畜禽粪便污染认识不足、处理不科学,对粪污处理利用效率不高、农牧结合比例低,缺乏典型养殖模式、没有形成带动效应;推荐了适合畜牧业的循环经济发展模式:农牧有机结合,畜牧业与林业、渔业循环,畜牧业与其他产业之间的循环;提出了发展畜牧业循环经济的建议:完善畜牧业循环经济发展的保障体系,推广健康清洁的养殖模式,加强废弃物的资源化利用,推动畜牧业绿色发展,加快推进农牧结合的步伐,加快畜牧业产业化集群的发展。 相似文献

我国畜牧业循环经济发展途径探讨 总被引:8,自引:1,他引:7
<正>循环经济理论起源于20世纪60年代,兴起于90年代,是在面对全球资源枯竭、人口猛增、生态环境恶化等形势下,人类重新认识自然界、尊重客观规律的产物,是以资源的高效利用和循环利用为核心,以"减量化、再利用、资源化"为原则,以低消耗、低排放、高效率为基本特征,对"资源—产品—废弃物"的单向式传统增长模式转变为"资源—产品—废弃物—再生资源"的反馈式循环模式的根本变革,是可持续发展理念在经济增长中的具体应用。我国近年来对发展循环经济高度重视,国家出台了相应的政策措施大力推进其发展。畜牧业作为承农启工的中轴产业,是发展循环经济的重要环节。用循环经济理念引领畜牧业发展,对促进农业增效、农民增收、推进新农村建设、构建和谐社会具有重要作用和深远影响。本文就我国发展畜牧业循环经济的经济意义、模式和保障措施做一些探讨。 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
