牛奶酸奶、豆奶酸奶均是采用保加利亚乳酸杆菌和嗜热链球菌作为发酵剂而制成的。将这2种酸奶的样品用商业标准进行微生物的和感官性质的评价。牛奶酸奶的含水率为83.3%左右,豆奶酸奶的含水率为9119%左右。豆奶酸奶的蛋白质含量为6.6%,大大高出了牛奶酸奶(3.0%)。牛奶酸奶中的脂肪和灰分含量比较高,分别为6,5%和0.6%,但两者的镁盐成分含量变化不大(P〈0.05)。牛奶酸奶的pH值为4.1,豆奶酸奶的pH值为5.4。牛奶酸奶中所含的活细菌数比较大,为11×10^5CFU/mL。通过以上分析和出于商业成本考虑,豆奶酸奶可以成为牛奶酸奶的一个很好的替代品。 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

本试验旨在研究两种绿头鸭(白羽绿头鸭和绿头鸭)肌肉营养组成和价值,为绿头鸭肉产品的开发利用提供基础数据和理论依据。选择白羽绿头鸭和绿头鸭60只(每个品种各30只,公母各半),依照国家标准测定胸肌粗蛋白质、粗脂肪、胆固醇含量及氨基酸、脂肪酸、微量元素和维生素的组成和含量,并对胸肌进行氨基酸评价及脂肪酸营养价值评价。结果显示,白羽绿头鸭肌肉粗蛋白质含量显著低于绿头鸭(P<0.05);两种绿头鸭肌肉中均检测到17种含量大于0.01%的氨基酸,其中白羽绿头鸭肌肉苏氨酸、组氨酸、丝氨酸和脯氨酸含量显著高于绿头鸭(P<0.05),赖氨酸、谷氨酸和精氨酸含量显著低于绿头鸭(P<0.05);检测到13种含量均大于0.01%的脂肪酸,其中白羽绿头鸭硬脂酸和油酸含量显著低于绿头鸭(P<0.05);检测到9种矿物质元素(钠、镁、钾、钙、锰、铁、铜、锌和硒),两种绿头鸭差异不显著(P>0.05);检测到8种维生素,白羽绿头鸭肌肉维生素B1含量显著高于绿头鸭(P<0.05),维生素D和维生素E含量显著低于绿头鸭(P<0.05)。两种绿头鸭肌肉氨基酸比例接近世卫组织推荐的理想模式,富含人体所需的矿物质元素和维生素,具有广阔的开发利用前景。 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: Clinical experiences indicate that centesis of the lateral compartment of the femorotibial joint is often unsuccessful. Objective: To determine the accuracy of 2 published and 2 unpublished techniques of centesis of the lateral compartment of the femorotibial joint. Hypothesis: It was hypothesised that a drug can be administered into the lateral compartment of the femorotibial joint via a diverticulum of this joint that surrounds the medial aspect of the long digital extensor tendon and that this technique is more accurate than described techniques of centesis of this compartment. Methods: Twenty‐four stifles of 12 horses were divided equally into 4 groups and a radiocontrast medium injected into the lateral compartment of the femorotibial joint of each group using a hypodermic needle inserted: 1) caudal to the lateral patellar ligament and proximal to the tibial plateau, 2) caudal to the long digital extensor tendon and proximal to the tibial plateau, 3) between the long digital extensor tendon and bone of the extensor groove of the tibia or 4) directly through the long digital extensor tendon until it contacted bone. Twelve veterinary students who had no experience using any of these techniques performed the injections. Accuracy of each technique was determined by examining radiographs obtained after injecting the contrast medium. Results: The most successful technique for arthrocentesis was by inserting a needle through the long digital extensor tendon. This approach was successful in all attempted cases, whilst other techniques had lower rates of success. Conclusions: The lateral compartment of the femorotibial joint can be accessed accurately by inserting a needle through the long digital extensor tendon as it lies within the extensor groove. Other techniques may not be as accurate for clinicians inexperienced in arthrocentesis of the lateral compartment of the femorotibial joint. 相似文献

A retrospective review of records of 205 cats with histologically confirmed disease of the spinal cord was performed to identify the prevalence of disease in this nonrandomly selected population of cats. Clinical records were reviewed, and age, duration of neurologic illness, and clinical and histopathologic findings in cats with spinal cord disease were abstracted. Disease processes were classified into 7 categories and 23 groups. The most common diseases affecting the spinal cord of cats were feline infectious peritonitis (FIP), lymphosarcoma (LSA), and neoplasia of the vertebral column secondarily affecting the spinal cord. Information on age, onset and duration of clinical signs, and lesion localization at the postmortem examination in cats belonging to the 7 categories of disease were analyzed to create a practical list of differential diagnoses. Cats were also subcategorized into 3 groups based on their age at death. FIP was the most common disease of cats younger than 2 years of age. LSA and vertebral column neoplasia were the most common diseases affecting cats between 2 and 8 years of age. Vertebral column neoplasia was the most common disease affecting cats older than 8 years of age. Results of this histopathologic study showed that FIP and LSA were the most common disease processes affecting the spinal cord of cats. However, at least 21 other groups of diseases and their relative prevalence were identified. 相似文献

根据JJF1059-1999《测量不确定度评定与表示》建立了高效液相色谱法测定鸡肉中土霉素残留测量的不确定度评定方法,评定过程包括建立测量程序、分析不确定度来源、对不确定度分量进行量化。将不确定度归类为两大类。随机效应导致的不确定度可以通过一系列具有统计意义的重复观测值进行A类评定;系统效应导致的不确定度通过各测量器具、设备的说明书、校准证书提供的参数进行B类评定。本方法鸡肉中土霉素残留量的相对合成标准不确定度约为3.9%。 相似文献
