2013年上半年赖氨酸市场回顾及下半年展望

2013年上半年,我国赖氨酸市场延续上一年供应失衡,赖氨酸市场价格跌破市场心理预期。上半年在生猪养殖效益低下,玉米原料居高的背景下,赖氨酸厂家降价促销,新老厂家分散投产加速市场供应压力,上半年赖氨酸市场价格整体震荡向下趋势明显。本文主要从赖氨酸进出口量及国内外市场价格走势等方面对2013年上半年赖氨酸市场进行回顾,并对下半年赖氨酸市场价     

赖氨酸2006年市场回顾及2007年展望

中国的赖氨酸产业在2006年又获得了长足发展。产能和产量连破新高，已经成为赖氨酸的“世界工厂”。产量之大，已经对世界赖氨酸市场产生了重要影响。2006年，进口赖氨酸数量仅占市场需求量很小的份额，国产赖氨酸的市场话语权进一步巩固。全年市场基本平稳，仅在10月份出现一次逆市高涨，但很快恢复平静。

中国氨基酸市场十年回放(2000—2010年)

2003年以前,由于供应格局相对稳定,在饲料中大量应用的蛋氨酸和赖氨酸的价格受到相关替代品价格(玉米、豆粕)的影响(影子价格)。而随着中国赖氨酸生产企业进入市场,供应格局发生了较大变化,产品定价的主要因素由影子价格转向供需。2007年以来,外部环境的剧烈变化,谷物和蛋白原料价格大幅无规则波动,对氨基酸使用提出了更复杂的要求,因此,经过不断摸索与研发,中国在苏氨酸、色氨酸发面飞速发展;同时,在蛋氨酸生产方面也取得了一定进展,有望实现国产化。中国真正意义上的赖氨酸规模化生产起始于2000年,十余年的快速发展,跨越了国外企业40年的路程。而未来的3—5年,或许是中国氨基酸产业整合成熟的5年,在这里,我们会将过去10年中国氨基酸产业所发生的大事进行梳理。

Heartworm in dogs in Canada in 1984

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal.

Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection.
