牛子宫内膜炎的防治技术

牛子宫内膜炎是牛子宫黏膜发生黏液性或脓性炎症,是产后或流产后最常见的一种生殖器官疾病。(一)子宫内膜炎的类型1.急性子宫内膜炎。常发于产后2～3天,多由产后内源性或外源性感染引起,以卡他性炎症为特点。病牛体温略升高,达39.5～40.9℃,食欲明显减退,个别废绝,精神不振,常努责作排尿状,由阴门排出炎性黏液,后期排出脓性分泌物,卧地时排出量更大。急性子宫内膜炎未及时

母猪子宫内膜炎的防治

子宫内膜炎是母猪常见的一种生殖器官疾病。主要临床表现为:急性子宫内膜炎多见于产后母猪,病猪体温升高,精神沉郁,食欲减退或废绝,常卧地,频尿, 从阴门排出大量灰红色或黄白色有臭味的黏液性或脓性分泌物,严重者呈污红色或棕色。慢性子宫内膜炎多由急性炎症转变而来,从阴门排出脓性分泌物,猪栏地面常见到白色似石灰渣状粉末,往往无明显全身症状, 部分猪仍可定期发情,但屡配不孕。     

几种奶牛繁殖障碍病的诊治

奶牛的繁殖障碍性疾病是导致奶牛屡配不孕的主要原因,正确诊断是关键。1子宫内膜炎1.1脓性子宫内膜炎诊断:产后胎衣不下或部分不下,恶露排出不停,环境卫生差等都可以导致子宫内膜发生炎症。表现为经常排出脓性分泌物,尾部附有结痂。     

母猪子宫内膜炎防治

<正>子宫内膜炎通常是指子宫黏膜的黏液性或脓性炎症,为母猪的常见生殖疾病。1病因配种、分娩及助产时,病原微生物侵入可引发本病。子宫黏膜的损伤及母畜抵抗力降低是促发本病的重要原因。本病可继发于难产、胎衣不下、子宫脱出、产道损伤等。2症状2.1急性子宫内膜炎病猪食欲减退,体温升高,拱背,频频排尿,阴门排出灰白色、含絮状物的分泌物或脓性分泌物,其卧下时,分泌物排出较多。阴道检查,见母猪子宫颈外口肿胀、充血,     

母猪产后子宫内膜炎的防治

母猪产后子宫内膜炎发病率较高 ,也可转变成慢性或隐性子宫内膜炎 ,是导致母猪不孕的主要疾病之一。在屡配不孕的母猪中 ,有 5 0 %由于患此病而被淘汰 ,这种情况在引进的纯种母猪中尤为突出。母猪在产仔过程中阴道受到污染是造成产后子宫内膜炎的主要原因。对于大多数母猪来说 ,在分娩过程中 ,子宫都不可避免地会受到污染 ,产后子宫或阴道都会出现短暂的炎症过程。如果母猪仅在产后 10d内 ,阴道有脓性分泌物排出 ,而不影响断奶后配种 ,则预后大多良好。但有部分纯种母猪 ,阴道脓性分泌物在产后 2 0d后仍有排出 ,往往导致配种率降低。预防措…

Comparison of 2 methods of centesis of the bursa of the biceps brachii tendon of horses

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.

鸡败血支原体垂直传播模式及其阻断方法

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。     

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF

Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo.
