草原滩鸡冬季的管理要点

滩鸡又称草原鸡、趴地鸡等，以在草原、山地、果园放牧饲养为主，补饲为辅。是集约化养鸡由舍内向舍外的延伸．因产品污染小、风味独特、营养丰富，迎合了消费者对安全食品的需求．需求量也逐年增加，滩鸡的饲养也逐渐成为宁夏盐池县第二支柱产业。由于冬季是滩鸡销售旺季，饲养量大、鸡群密度过高．生产者为了充分发挥鸡的生产潜能．使鸡群始终处于高度紧张的生产状态，     

盐池县草原滩鸡发展模式探讨

草原滩鸡养殖是盐池县自2002年11月全面实行草原封山禁牧后,为探索和科学利用草场资源,有效增加农民收入,探索出的一条适合当地畜牧业发展的新路子。为了使这一新型产业快速、高效、可持续发展,最终实现经济效益、生态效益同步发展,县委、政府提出了“以滩羊为主,多畜禽并举”、“羊进圈,鸡出滩”的发展思路,并且积极争取项目,多渠道筹措资金,大力鼓励、扶持草原滩鸡养殖,初步形成产业框架,成为全县畜牧业经济的新增长点。     

宁夏草原(滩)鸡的推广

近年来．宁夏养禽业有了长足发展．特别是草原（滩）鸡的养殖成为禽业发展的一大亮点。草原（滩）鸡养殖不仅节约了成本．生产出符合人类健康需求的绿色禽产品．提高了农牧民的收入．而且把草业和禽业有机地结合起来．促进了生态的良性循环。     

浅谈宁夏草原(滩) 鸡发展应注意的问题

宁夏回族自治区地处西北边陲,有着大量的天然草场,草畜产业在牧业中占有很重要的地位.近年来,养禽业有了长足的发展,特别是草原(滩)鸡的养殖成为禽业发展的一大亮点,它不仅节约了成本,生产出符合人类健康需求的绿色畜产品,提高了农牧民的收入,而且把草业和禽业有机地结合起来,促进了生态的良性循环.但也同时发现在草原鸡生产中存在许多问题.比如,选址不科学,饲养管理粗放混乱,不注重草原补播和人工种草,出现破坏草场植被的情况.本文就如何发展草原(滩)鸡谈些粗浅看法.

Heartworm in dogs in Canada in 1989

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded.

Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas.
