2021年1月8日,我国生猪期货在大连商品交易所上市,这是我国第1个畜牧类活体期货交易品种。生猪期货作为现货市场的有效补充,其价格发现功能可以为我国生猪养殖及上下游行业价格波动提供有效规避风险的工具,对生猪市场平稳有序发展具有重要意义。目前生猪期货上市后,依然存在期货交割标的难以标准化、期货交易风险较高等问题,制约了我国生猪期货的发展。本文采用SWOT分析法系统地梳理了我国生猪期货发展的优劣势,分析了生猪期货发展面临的机遇和挑战,以期为我国生猪期货发展提供决策参考。 相似文献

自2021年1月8日我国生猪期货上市以来,生猪期货的价格发现功能被业内高度关注,生猪期货价格对猪肉现货价格的指导与价格平抑作用效果备受关注。基于猪肉价格的主要影响因素,本文选择了猪的饲料价格、屠宰加工成本、牛肉价格(猪肉替代品)、生猪期货价格和猪肉价格作为变量,创建VAR模型,使用了2021年4月至2022年4月的周平均数据,采用协整检验、Granger检验和脉冲分析等方法研究生猪期货对我国猪肉价格短期波动的规律。结果显示,饲料价格的波动和生猪期货价格的波动是引起猪肉价格短期波动的主要因素。由此提出维持饲料价格稳定、完善生猪期货市场制度、引导生猪养殖企业运用生猪期货套期保值进行风险避险等政策建议。 相似文献

摘要：长期以来“猪周期”给我国生猪产业链相关的养殖企业和上游企业带来巨大的风险和不确定性,而具有价格发现和规避风险功能的生猪期货合约能够很好地对冲一些生猪市场上的不确定性。生猪期货的上市将为我国生猪养殖业带来积极和深远的影响;同时“保险+期货”项目的迭代升级也将促进生猪期货的发展。 相似文献

猪肉作为我国人民的主要肉类消费品,其剧烈的价格波动会给养殖户、屠宰及加工户、零售商带来较大风险。文章首先分析了生猪期货市场实现稳定现货价格的作用机制。笔者认为,生猪期货主要将通过促进养殖规模化、提升现货市场标准化、发挥套期保值功能、发挥价格发现功能四种机制,稳定生猪产业供给端和需求端。最后该文结合我国生猪市场情况,针对如何帮助生猪期货更好地发挥其功能,从规模化养殖,提高疫病防控水平,养殖户期货知识普及,市场标准化,交割方式等五个方面提出政策建议。 相似文献

我国既是生猪生产大国,也是猪肉消费大国,利用期货市场促进生猪供给和价格的稳定,对于保障相关产业健康发展和社会经济的稳定具有重要意义。虽然上市生猪期货具有很重要的意义和作用,但目前依然存在很多制约因素,只有这些问题解决了,才能适时推出生猪期货。 相似文献

近年来,生猪价格大起大落,养殖企业苦于没有避险工具。期货市场一直盼望生猪这个品种上市,但为什么却迟迟不能上市?据专家分析:生猪期货至今没有上市的原因是多方面的,主要有三个方面:一是标的物的确定仍在讨论阶段,国内生猪不同质量等级对应价格有很大的差异,这给交割品级的设定带来了难度;二是养殖行业仍处于规模化进程中,中小养殖户即使有了生猪期货也难有能力去真正利用期货作为避险工具,在行业本身集中度略有欠缺的情况下,生猪期货的上市需要谨慎;三是目前国内整体养殖行业仍处于生产相对分散的格局,这种情况下生猪期货充分发挥价格发现的功能是有限的。那生猪期货到底能不能为我国的生猪市场带来一线希望?本期就让我们一起探讨生猪期货的那些事…… 相似文献

如何看待将"出炉"的生猪期货 总被引：2，自引：0，他引：2
随着我国期货行业的发展,农产品期货大部分已经上市,市场交易量和参与度越来越广泛,期货市场越来越影响企业甚至一个行业的发展进程.期货市场对现货市场的价格预期及套期保值等作用深受相关企业的追捧.我国是生猪生产、消费和贸易大国,年生猪产量占世界总产量的50%以上.生猪养殖与消费范围广泛,质量标准与检验检疫法规体系健全,品种、等级易于划分,比较适合开展期货交易.生猪现货价格具有较强波动性,生猪期货的上市将对稳定我国整个生猪相关产业链条的有序发展起到决定性作用.本文主要围绕美国生猪期货现状及我国生猪期货未来上市的作用意义加以阐述.[编者按] 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

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
