1玉米冲高回落
广东11月份玉米市场价格罕见地反季节暴涨,月内玉米价格最大涨幅250元/t。据业内人士介绍,11月份玉米价格暴涨风席卷全国市场的主要原因:一是东北产区新玉米未能大批上市;二是出口玉米商急于组织货源:三是玉米深加工企业需要原料开工:四是广东码头玉米现货少.船期断续。在此影响下,广东码头有玉米经销商立即将现货封仓,即时抬价,甚至连合同也不兑现。有饲料厂投诉。价格暴涨后,经贸商拒不执行前期签订的购货合同,更别说口头协议,诚信度令人心寒。幸好广东地区大型饲料厂都囤有1-2个月的库存,否则市场状况真的不敢想象。随着新玉米上市量的增加,11月下旬价格开始回落。码头信息显示,11月底仅锦州港就将有近35万t玉米抵粤,预计玉米价格将逐步缓慢下调。 相似文献

8月20日,桂林市场东北和河南产玉米车站成交价格在1310~1330元/吨,市场批发价格在1340~1360元/吨,保持平稳;南方新玉米价格在1300元/吨左右,保持相对平稳,目前价格比上年同期低100-120元/吨。目前桂林市场南方新产玉米全面上市,虽然今年南方新玉米质量相对上年差,但由于天气较好,水分相对较低,价格也比北方玉米低50元/吨左右,因此饲料厂和养殖户仍然乐于采购和使用新玉米,当然由于数量相对不足,不能大批量满足厂家和养殖户的需求。届市国内玉米市场价格将保持相对平稳中有所波动下滑的态势。原因:一是目前国内产区玉米长势较好,大幅减产的预期已落空,预计今年玉米总产量不会有太大的下降;二是当前南方新玉米上市,可能在北方新玉米上市前满足一部分需求,特别是中秋节前养殖业的旺季需求,缓和南方供需矛盾;三是下个月中下旬起,河南等地新玉米就可上市,到时,国内玉米供给又将增加,销区对东北玉米的需求将继续有所下降;四是新玉米的上市.价格的相对较低.拉动国内玉米价格整体水平也有所降低;五是由于国际运费的下降,人民币的升值.后市国内玉米出口将有所减少;六是中秋节后.养殖业将进入季节性淡季.饲料需求会有所下降。 相似文献

近期,国内玉米市场已经出现分市格局,关内部分地区玉米市场开始出现触底反弹,玉米价格振荡走强。东北地区新玉米仍未批量上市,玉米价格仍有继续下跌动力.但下跌空间较为有限。后期铁路运输仍然趋紧,且饲料企业玉米库存普遍薄弱,国内玉米市场已进入买方看市阶段,买方的采购举动对市场的影响增强,具体分析如下: 相似文献

近期,随着东北新粮批量上市,加上需求疲软。国内玉米市场呈现供大于求的特点.同时,国家持续在南方销区拍卖玉米,增加销区玉米市场供给.导致当前玉米期现价格稳步下跌。期货市场玉米价格下跌将近200元/吨,北方港口标准玉米平仓价格和南方销区价格亦同步下跌.市场各方开始对后市玉米价格走势抱有一定悲观态度。 相似文献

八月份,玉米市场在人们预期价格上涨的需求旺季,因人民币上涨、出口受阻等各种利空因素的抑制作用。玉米价格未能达到预期高点,目前产销区正处于振荡整理态势。后期销区饲料养殖业对玉米的需求能否有效增加.影响价格的潜在因素能否对价格造成打压成为市场普遍关注的焦点。笔者认为。今年国内玉米价格高峰已经过去,后期国内玉米价格将在新季玉米丰收的压力下稳中回落。 相似文献

2011年的玉米市场上演疯狂行情,由于新玉米受到中秋前后华北地区连续的阴雨天气的影响,新玉米推迟半个月左右上市,导致局部地区供应非常紧张,随时面临断货的危险,陈玉米价格9月份疯涨一约200元/吨,大连平仓价最高冲至2540元/吨,广深码头价2660元/吨,创历史新高。笔者在近期走访了河南河北产区,就陈玉米价格的高企对今年新玉米市场的走势影响,作如下分析。 相似文献

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog 总被引:1,自引:0,他引:1
Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum. 相似文献

嗅源是军犬嗅觉作业训练的依据.军犬鉴别中嗅源能力的培养在整个鉴别训练中占有重要地位,关系到鉴别训练的成败和鉴别能力的提高.所以,军犬在嗅认嗅源时必须按照训犬员的指令充分、细致地感受嗅源气味,并且对嗅源气味产生兴奋反应.如何培养军犬充分嗅认嗅源以及及时解决嗅认过程中出现的问题,成为我们进行鉴别训练的关键.…… 相似文献

As there is no statistical evidence that saddle fit influences the load exerted on a horse's back, this study was performed to assess the hypothesis that the width of the tree significantly alters the pressure distribution on the back beneath the saddle. Nineteen sound horses were ridden at walk and trot on a treadmill with three saddles differing only in tree width. Kinetic data were recorded by a sensor mat. A minimum of 14 motion cycles were used in each trial. The saddles were classified into four groups depending on fit. For each horse, the saddle with the lowest overall force (LOF) was determined. Saddles were classified as "too-narrow" if they were one size (2 cm) narrower than the LOF saddle, and "too-wide" if they were one size (2 cm) wider than the LOF saddle. Saddles two sizes wider than LOF saddles were classified as "very-wide". In the group of narrow saddles, the pressure in the caudal third (walk 0.63 N/cm(2)+/-0.10; trot 1.08 N/cm(2)+/-0.26) was significantly higher compared to the LOF saddles (walk 0.50 N/cm(2)+/-0.09; trot 0.86 N/cm(2)+/-0.28). In the middle transversal third, the pressure of the wide saddles (walk 0.73 N/cm(2)+/-0.06; trot 1.52 N/cm(2)+/-0.19) and very-wide saddles (walk 0.77 N/cm(2)+/-0.06; trot 1.57 N/cm(2)+/-0.19) was significantly higher compared to LOF saddles (walk 0.65 N/cm(2)+/-0.10/ 0.63 N/cm(2)+/-0.11; trot 1.33 N/cm(2)+/-0.22/1.27 N/cm(2)+/-0.20). This study demonstrates that the load under poorly fitting saddles is distributed over a smaller area than under properly fitting saddles, leading to potentially harmful pressures peaks. 相似文献

Observations on the Pathology of the Spleen of the Cat 总被引:1,自引:0,他引:1
Abstract— Lesions were found in the spleen of four of sixty-three cats examined post mortem in the department, and comprised two examples of lymphosarcoma, one of chronic fibrinous peritonitis and one of subcapsular haematoma. Abnormalities were found in two cat spleens received from veterinary surgeons in general practice. In one cat the abnormalities were an haemangiosarcoma with secondary deposits in the liver and in the other extensive mast cell infiltration. In addition lesions were detected in the spleen of three of eighty-seven cats examined post mortem in general practice. The lesions were: multiple secondary deposits of adenocarcinoma from a primary tumour of the mammary gland, a ruptured spleen and a foreign body below the splenic capsule. Résumé— L'examen microscopique de soixante-trois chats pratiqué dans le service a permis de rencontrer quatre fois des lésions de la rate, dont deux lymphosarcomes, une péritonite capsulaire fibrineuse et un hématome sous-capsulaire. D'autre part des lésions ont été trouvées dans deux rates de chat expédiées par des vétérinaires exerçant en pratiaue générale. Chez un chat il s'agissait d'un htmangiosarcome avec métastases hépatiques et chex l'autre d'une infilt ation diffuse par des mastocyta. De plus, on a rencontré des llésions dnas la rate de trois chats parmi quatre-vingt sept autopsies effectuées dans le cadre d'une clientèle génárale. Ces iésions étaient dés métastases multiples d'un adénocarcinome dont la tumeur primitive siègeait dam la glande mammaire, une rupture de la rate et un corps érangers sou capsulaire. Zusammenfassung— Läsionen der Milz wurden bei vier von dreiuiidsechzig in dieser hbteilung sezierten Katzen gefunden, und zwar in zwei Fällen ein Lymphosarkom, in einem Falle eine chron-ische fibrinöse Peritonitis und in einem ein subkapsuläres Hématom. Anomalien fanden sich auch in der Milz von zwei Katzen, die aus der tierxrztlichen Praxis eingesandt wurden. Bei der einen Katze war dies ein Hämangiosarkom mit Metastasen in der Leber, bei der anderen eine weitläufige Infiltration der Mastzellen. Außerdem wurden bei drei von siebenundachtzig in der Praxis sezierten Katzen Milzläsionen gefunden. Diese bestanden am multiplen Metastasen eines Adenokarzinoms der Brustdrüse, einer Milzzerreissung und einem Fremdkörper unterhalb der Milzkapsel. 相似文献
