由于蚯蚓本身为高蛋白药材,且中草药作为饲料添加剂具有低残留、少污染和促生产等优点,因此本试验探究了干蚯蚓中草药复合添加剂检测对产蛋鸡生产性能和蛋白质的影响。试验选用144只海兰白蛋鸡,分3个处理饲喂:玉米豆粕型饲粮(对照组)、3%干蚯蚓代替豆粕3%(处理1)、3%干蚯蚓中草药添加剂代替豆粕3%(处理2),每个处理设3个重复,且每个重复16只海兰白蛋鸡。试验结果表明:试验组与对照组相比,产蛋率与蛋重均显著提高,且处理1与处理2产蛋率分别显著提高2.3%和4.9%;处理1与处理2的蛋重分别显著提高2.7%和5.8%。因此可知,干蚯蚓添加剂和干蚯蚓中草药复合添加剂均可提高蛋鸡产蛋性能,其中干蚯蚓中草药复合添加剂组效果更为突出。 相似文献

拉沙洛西钠(lasalocid Sodium)是一种包含在药用配合添加剂 Avotec 中的抗球虫制剂,它被明确规定只用于肉用仔鸡饲料中,当用在种鸡饲料时,可显著降低种蛋的受精率和孵化率。1985年1月到3月间,巴布亚新几内亚的3个主要家禽生产场报告,肉用型和蛋用型种鸡所产的蛋,受精率和孵化率显著降低。通过对两个农场提供的4价种鸡饲料样品分析表明,拉沙洛西钠含量分别为105、105、125和112ppm,A 农场仅喂给家禽污染饲料21 相似文献

中草药饲料添加剂对仙湖肉鸭生产性能和肠道微生物影响的研究 总被引：3，自引：0，他引：3
为评定中草药饲料添加剂对仙湖肉鸭生产性能和肠道微生物的影响,本研究选用0日龄商品代仙湖肉鸭270只,随机分成3个处理,每个处理6个重复,每个重复15只鸭,其中试验组Ⅰ在基础日粮的基础上添加1.5%的补气活血、疏肝健脾的中草药饲料添加剂;试验组Ⅱ在基础日粮基础上添加1.5%补肾益脾、活血降脂的中草药饲料添加剂;试验组Ⅲ为对照组,饲养期为49 d。结果表明:与对照组相比,试验组Ⅰ仙湖肉鸭的日增重显著提高(P<0.05),提高幅度为3.6%;试验组Ⅱ日增重有提高的趋势,但差异不显著(P>0.05)。试验组Ⅰ和Ⅱ均显著地提高了饲料转化率(P<0.01),提高幅度分别为3.8%和2.4%。与对照组相比,试验组Ⅰ和Ⅱ仙湖肉鸭肠道内大肠杆菌的数量均显著降低(P<0.05),乳酸菌的数量显著提高(P<0.01),且试验组Ⅰ要优于试验组Ⅱ(P<0.05)。说明日粮中添加一定比例的中草药饲料添加剂能够在一定程度上促进肠道内有益菌的繁殖,改善肉鸭的生产性能。 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
