如何减少畜禽体内脂肪的过多沉积已成为肉品工业和消费者普遍关注的焦点 ,因此 ,人们一直在寻求降低肉品脂肪含量的方法。脂肪细胞膜免疫技术是一种降低动物脂肪的新方法。该方法是以从动物脂肪细胞膜分离得到的膜蛋白作抗原 ,通过被动免疫或主动免疫来破坏脂肪细胞 ,使脂肪组织中细胞的数量减少 ,限制其贮存脂肪的能力 ,从而达到调控动物生长和降低体脂的目的。虽然有时也会产生一定的副作用 ,但仍具有明显的优点。文章对脂肪细胞膜免疫的方法、作用机理、对动物生产性能、屠宰率、胴体品质、血液的影响以及脂肪细胞膜免疫中存在的问题进行了综述 ,并展望了脂肪细胞膜免疫的发展方向及应用前景 相似文献

为了验证针对酒精阳性乳（alcohol positive milk,AMP）发病机理制作的新型预混料对奶牛酒精阳性乳的防治效果,本研究设计了试验1和试验2：在试验1中,根据泌乳天数、酒精阳性乳程度,采用完全随机区组方法将100头荷斯坦泌乳后期牛分为对照组、低剂量（LDG）、中剂量（MDG）和高剂量组（HDG）,每组5个重复,每个重复5头牛,各组在日粮中依次添加0、50、100和150 g/（头·d）新型预混料,试验期26 d,3 d为1个采样周期;在试验2中,按照试验1的分组方法,将370头荷斯坦泌乳后期奶牛分为对照组和试验组,每组185头,在日粮中依次添加0和100 g/（头·d）新型预混料,试验期35 d,每5 d为1个采样周期。将奶样与等量的75%中性酒精混合,通过观察奶样状态判断酒精阳性乳发生程度。试验1结果表明,与对照组相比,在日粮中添加50 g/（头·d）新型预混料对酒精阳性乳的发生率有一定的影响（P>0.05）;日粮中添加100和150 g/（头·d）新型预混料能显著降低酒精阳性乳发生率（P<0.05）,尤其对降低强阳性酒精阳性乳发生率效果极显著（P<0.01）,但两组之间差异不显著（P>0.05）。试验2结果表明,到试验结束时,日粮中添加100 g/（头·d）新型预混料可使酒精阳性乳总发生率降低75.73%,强阳性酒精阳性乳发生率降低90.82%。以上结果表明,新型预混料能有效防治奶牛酒精阳性乳的发生,且日粮中新型预混料的最佳添加量是100 g/（头·d）。 相似文献

In gnotobiotical and conventional piglets infected a day post partum (DPP) with oocysts of the coccidium Isospora suis, densitometrical analysis of the activity of aminopeptidase M (EC.3.4.11.2; APM) was performed in the area of microvillous zone of the small intestine. Piglets were infected with different infection doses of oocysts (100,000 oocysts) in gnotobiotical piglets and 200,000 oocysts in conventional piglets). In infected gnotobiotical piglets, the APM activity was studied in the period from the 3rd to 11th day after infection (DAI) and in infected conventional piglets in the period of to the 2nd to 10th day after infection (DAI). Control piglets, in the group of the gnotobiotical animals at the age of 2 to 5 days in the group of the conventional animals at the age of 4 to 7 days, had different APM activity in the microvillous zone of the intestinal mucosa. It was stated that the microvillous zone of the intestinal mucosa gained higher values in control conventional piglets (+7.01 mean values of density). In infected gnotobiotical piglets the density fall of the reaction product of APM was demonstrated already on the third day with further marked reduction of APM density on the 4th day after infection in the whole small intestine with predominance of the persisting APM activity in ileum. Even despite the slight increase in the density of the reaction product of APM in the period from the 5th to 7th DAI (the highest increase in APM density on the 6th DAI), a further decrease of the activity was recorded again on the 8th and namely the 9th DAI in the whole small intestine (the lowest value of density was found in the rear jejunum), the ileum mucosa being affected, too. A slightly higher density of the reaction product of APM was found in the duodenum. On the 10th DAI the APM density started to change and on the 11th DAI in the duodenum and in the middle jejunum it even reached higher values in comparison with the control data. Some differences were proved in the infected conventional piglets in comparison with the development of the APM activity in the small intestine mucosa in the infected gnotobiotical piglets. On the 3rd and 4th DAI APM defect occurred in the whole small intestine, with APM density prevailing in the ileum mucosa (like in the group of infected gnotobiotical piglets). The second period of decrease in APM activity lasted for almost four days (6th to 9th DAI).(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献

Arrector pili muscle (APM) hamartoma is reported in humans and dogs. We describe a linear APM hamartoma in a sphynx cat. The lesion was characterized by multiple nodules distributed linearly along the tail, made of randomly arranged hypertrophic smooth muscles, the size of which tended to wax-and-wane during a one year follow-up. 相似文献

钙代谢及其相关激素与酒精阳性乳关系的研究 总被引：2，自引：0，他引：2
对低酸度酒精阳性乳患牛机体Ca、Mg进行检测,同时检测了其体内与Ca代谢相关激素的水平,探讨了Ca代谢及其相关激素与酒精阳性乳的关系。结果表明,患牛血清、乳清、全乳内Ca及乳清Mg含量均升高(P<0.05),全乳中Mg含量升高(P<0.01),而体内皮质醇(Cort)、甲状腺素(T4)与三碘甲腺原氨酸(T3)、甲状旁腺激素(PTH)含量均降低(分别为P<0.01,P<0.01,P<0.05,P<0.01),血清Mg、降钙素(CT)则变化不明显(P>0.05)。表明患牛处于慢性热应激状态,导致机体Ca代谢紊乱和乳汁中游离Ca、Mg水平升高,这是引起低酸度酒精阳性乳发生重要因素之一。 相似文献
