利用酒糟喂猪的几种新方法酒糟是酿酒业的副产品,产量高且数量大。采用以下几种新方法利用酒糟作饲料喂猪,可明显降低生产成本和提高养殖效益。一、烘干周喂。鲜酒糟在80~100℃的高温下烘干并粉碎,可有效降低残余酒精的含量,提高适日性和猪肉品质。酒糟粉粗蛋白... 相似文献

酒糟是生产酒精的副产品,市场上可购买到f酒糟或湿酒糟(含水分40-70%)。玉米酒糟是牛的极好饲料。酒糟与其他农业副产品混合饲喂是拓宽饲草供应、降低饲料成本的一种创新方法。酒糟含能量、蛋白质、脂肪和磷较高,因此,推荐将酒糟用于含上述养分低的饲料中。例如,干酒糟可与干甜菜渣和,或大豆皮以50:50的比例制成颗粒,而且这种混合比例制成的颗粒饲料有良好的硬度;[第一段] 相似文献

<正>1概念酒糟蛋白饲料,商品名称DDGS(Dis-tillers Dried Grains with Soluble),即含有可溶固形物的干酒糟,其主要指在现代化技术和设备的燃料乙醇工厂,用玉米籽实与精选酵母混合发酵生产乙醇和二氧化碳后,剩余的发酵残留物通过低温干燥形成的共生产品。在生产乙醇过程中,玉米中占籽实三分之二的淀粉发酵形成乙醇和二氧化碳,另外的三分之一则形成共生产品,由于这些共生产品蛋白质含量高,还富含脂肪、纤维等,同时由于微生物的作用,酒糟中蛋白质、B族维生素及氨基酸含量均比 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

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
