在奶牛人工授精工作中,有时会遇见发情母牛卵泡交替发育的现象。卵泡交替发育的母牛外部表现与正常发情牛一样,鸣叫,企图爬跨,接受爬跨,外阴部肿胀流蛋清样黏液,子宫口开张,卵泡在发情后35小时左右排卵。在第1次发情结束的7天左右时间,开始第2次重新发情,发情表现比第1次时外部性行为表现得更强烈。1诊断奶牛卵泡交替发育主要根据外部性行为天数来判定,两次发情间隔7天左右时间,可以初步判定为卵泡交替发育;同时要结合直肠检查,发现有成熟的卵泡存在,可以确定卵泡交替发育。2输精奶牛的卵泡交替发育在第2次发情时输精才能妊娠。如果交替发育… 相似文献

正近年来,在一些地方禽流感时有发生,当我们打开病死的腹腔,取出肝脏、腺胃、肌胃后就可以看到卵泡变形,以及卵泡充血出血的病变。但是新城疫、成年鸡白痢这两个疾病也会出现卵泡变形、出血,容易混淆,有些基层兽医技术人员只要看到卵泡变形就认为鸡感染了禽流感,往往忽视了对新城疫、成年鸡白痢的诊治,影响治疗效果,增加了死亡率。现在浅谈一下笔者对于禽流感、新城疫、成年鸡白痢卵泡变形的临床鉴别诊断。 相似文献

青年母牛在发情周期中卵泡发育波变化规律的研究 总被引:1,自引:0,他引:1
为揭示青年母牛卵泡生长发育的动态模式,作者利用B-型超声波诊断仪,对青年母牛在发情周期中卵泡生长发育的过程进行了连续观察。结果表明,卵巢上小卵泡(1~4 mm)、中卵泡(5~7 mm)和大卵泡(≥8 mm)的数量和直径均呈动态变化。大、中、小卵泡的数量、卵泡的发育要经历征集期、选择期、优势化、成熟期和闭锁退化的过程。青年母牛在整个发情周期中,优势卵泡的平均直径为13.6 mm,成熟卵泡的平均直径为13.80 mm,一个发情周期有3~4个卵泡发育波,其中有3个卵泡发育波的为多数(71.43%),有4个的为28.57%。 相似文献

Manual palpation or ultrasonographic examination of the cow's genital tract are currently used by veterinarians involved in reproductive management, but knowledge of the potential and the limitations of both methods is important to obtain an optimal accuracy in the diagnosis of physiological and pathological ovarian structures. This review presents the main features of manual and ultrasonographic characteristics of follicles, corpora lutea (with or without a cavity), follicular and lutenized cysts and the reliability of the two methods is compared. Manual diagnosis of follicles <10 mm is rather inaccurate, but ultrasound offers the possibility to diagnose follicles <5 mm and to measure their inner diameter. The predictive values of the presence or absence of a corpus luteum as determined by palpation are similar (78 vs. 75%). Manual or ultrasonographic diagnosis of the growing or regressing corpus luteum is rather difficult. The positive predictive value of a mature corpus luteum diagnosed by ultrasonography is lower (87%) than the negative predictive value (92%). Compared to manual palpation, ultrasonography permits a better estimation of the number and to determine more precisely the size of the mature corpus luteum. The positive values for follicular cysts diagnosed by palpation or by ultrasonography are 66 and 74% respectively, and for luteal cysts, the values are 66 and 85%, respectively.Manual palpation or ultrasonography are useful tools to diagnose ovarian structures in the cow. The accuracy of such methods can be enhanced by securing information on the reproductive history of the animal, palpation of uterine horns, vaginal examination or progesterone determinations. 相似文献

OBJECTIVE: To define the optimum period for sexing of Saanen goat fetuses by use of transrectal ultrasonography. ANIMALS: 82 Saanen goats pregnant with 124 fetuses. PROCEDURES: Fetal sexing was performed on the basis of the final location of the genital tubercle or identification of external genitalia. In experiment 1, fetuses (n = 78) were monitored every 48 hours from days 40 to 60 of gestation, whereas for experiment 2, 46 fetuses were examined only once between days 47 and 77 of gestation. RESULTS: For experiment 1, accuracy of fetal sexing was 20 of 20 (100%) for a single fetus, 39 of 42 (92.8%) for twin fetuses, and 10 of 16 (62.5%) for triplet fetuses. Diagnostic accuracy was significantly lower for triplet fetuses than that for single or twin fetuses. Final location of the genital tubercle was detected between 45 and 55 days of gestation (mean +/- SEM, 48.9 +/- 1.8 days). For experiment 2, accuracy of fetal sexing for a single fetus (24/24 [100%]) was significantly higher than the accuracy for twin fetuses (16/22 [72.7%]). Considering all fetuses that were born, accuracy of diagnosis was 69 of 78 (88.4%) for experiment 1 and 40 of 46 (86.9%) for experiment 2. Accuracy did not differ significantly between experiments. CONCLUSIONS AND CLINICAL RELEVANCE: Real-time ultrasonography after day 55 of gestation is a suitable method for determination of sex of Saanen goat fetuses by observation of the genital tubercle or identification of external genitalia. 相似文献

通过胎儿尾部和脐带之间的生殖器结节定位进行马性别诊断,雄性胎儿准确率97.8%(182/186),雌性胎儿99.4%(160/161)。胎儿性别测定的最适时间为妊娠后59d和68d之间。妊娠中期胎儿性别诊断也非常可靠。超声波性别鉴定准确率达100%。在雄性,从100d到220d妊娠常规获得阴茎或包皮的图像;在雌性,从118d到227d妊娠马观察到胎儿乳腺和乳头。在马繁殖上常规使用的5MHz线性传感器,大多数情况下一直可用到妊娠160d。当胎位太高或其大小超过超声设备监测范围时,须使用3.5MHz探头。若掌握好性别鉴定的最适时间和认识正确的解剖结构,两种方法都是非常精确的。 相似文献

Pancreatic disorders in dogs and cats are recognized with increasing frequency, and abdominal ultrasonography has assumed an important role in their diagnosis. The normal pancreas is a small, inconspicuous organ of comparable echogenicity to surrounding mesentery and may be difficult to identify. Therefore, knowledge of anatomic landmarks such as portal vein and contributing vessels, duodenum, and stomach is necessary to facilitate identification and examination. Pancreatic diseases and abnormalities frequently investigated by means of ultrasonography include pancreatitis, pseudocysts, abscesses, neoplastic lesions, and nodular hyperplasia. Disorders less commonly seen include exocrine pancreatic insufficiency, pancreatolithiasis, congenital anomalies, and pancreatic edema. Unfortunately, ultrasonographic findings in various pancreatic disorders overlap, and incidental findings or age-related changes may mimic pancreatic disease. On the other hand, pancreatic disorders may not cause changes in ultrasonographic appearance. Ultrasonographic findings, therefore, have to be judged in light of signalment, history, and laboratory data. Cytology or histopathology may be needed to establish a definite diagnosis. Despite these limitations, ultrasonography is useful in diagnosing pancreatic disease, guiding aspirates and biopsies, and monitoring response to treatment. 相似文献

The purpose of this paper was to analyse the aetiology and methods of diagnosing reproductive disorders in male dromedary camels. Male camel infertility manifests as one of three conditions: post-coital infertility (IG), inability to copulate (IC) and lack of sexual desire (LSD). IG is mainly a testicular disorder that is linked to a deteriorated seminogram, arrested spermatogenesis, Sertoli cell-only syndrome and testicular degeneration. For IG diagnosis, semen analysis, testicular biopsy and fine-needle aspiration are gold standards. Testicular ultrasonography was generally inefficient. High serum FSH was found in IG camels with oligo- and azoospermia, implying primary spermatogenesis defects. The testis-expressed protein (TEX101) and the epididymis-expressed protein (ECM1) are reliable biomarkers for distinguishing between obstructive and non-obstructive azoospermia. IC manifests in two forms: phimosis (PHI) and erectile dysfunction (ED). PHI is frequently linked to preputial and penile pathologies, as well as leucocytosis, neutrophilia and elevated nitric oxide metabolites. The majority of camels with ED have normal genital organs, and the condition is associated with an increase in cardiac troponin I. LSD is a rare disorder brought on by hormonal imbalances, high temperatures, stress and debilitating diseases. In conclusion, IG diagnosis necessitates semen analysis, testicular biopsy or fine-needle aspiration, and FSH testing, whereas IC diagnosis requires preputial and penile examinations. Diagnostic aids include serum and seminal biomarkers. 相似文献

Abdominal radiography and ultrasonography are commonly used as part of the initial diagnostic plan for cats with nonspecific signs of abdominal disease. This retrospective study compared the clinical usefulness of abdominal radiography and ultrasonography in 105 feline patients with signs of abdominal disease. The final diagnosis was determined more commonly with ultrasonography (59%) compared to radiography (25.7%). Ultrasonography was also able to provide additional clinically relevant information in 76% of cases, and changed or refined the diagnosis in 47% of cases. Based on these findings, ultrasonography may be sufficient as an initial diagnostic test for the investigation of feline abdominal disease. 相似文献

Retrobulbar abscessation is the most common orbital disease of rabbits, and the lesions are notoriously difficult to treat successfully. This article describes the diagnosis, surgical treatment, and long-term management of an extensive abscess located within the right maxilla and retrobulbar space of a domestic rabbit. Preoperative assessment and long-term monitoring were achieved with a combination of radiography, ophthalmic ultrasonography, and CT. Extraoral rigid endoscopy via a fenestration in the maxilla was used to facilitate surgical debridement of the lesion, and extraction of multiple cheek teeth has been fundamental to achieving control. The long-term use of topical and systemic antibiotic preparations and nonsteroidal anti-inflammatory medication is discussed. 相似文献

This review deals with the relevant literature about the application of ultrasonography in udder diagnosis especially in stenosis of the teat in cattle. Ultrasonic devices, frequencies and ultrasonic techniques are discussed. It seems that under practical conditions, a 5 MHz linear scanner might be sufficient. Compared with radiography, ultrasonography gave better results in high and medium stenoses of the teat. The results of these first investigations demonstrated that with the development of suitable devices and techniques, ultrasonography might be of high importance as an additional and supporting technique for the diagnosis of stenoses of the teat. 相似文献

The aim of the present study was to describe the temperature of the different portions
of the female genital tract and their relation to rectal temperature and to investigate
the effect of steroid hormones profiles on these variables over the estrous cycle in
cattle. Four nonpregnant Japanese Black cows were investigated daily over two successive
estrous cycles using a digital thermometer with a long probe and rounded-end sensor to
record the temperature of the rectum (RT), vagina (VT), cervix (CT), uterine body (UBT)
and uterine horns (UHT). Blood samples were collected immediately before temperature
recording to assay peripheral levels of progesterone (P4) and estradiol-17β
(E2). Moreover, transrectal ultrasonography was carried out after temperature
recording to monitor the ovulatory follicle and track ovulation. During the experiment,
the ambient temperature and relative humidity were recorded for further calculation of the
temperature humidity index (THI). The temperature within the genital tracts in these cows
progressively increased towards the uterine horns from the vagina. The VT, CT, UBT and
UHTs were significantly higher in association with peripheral P4 concentrations
greater than 4 ng/ml (mid-luteal phase) when compared with lower peripheral P4
concentrations. The VT was more significantly (P<0.01) correlated to the CT, UBT and
UHTs than RT. In conclusion, a temperature gradient was present among the vagina, cervix
and uterus over the estrous cycle, and changes in peripheral P4 concentrations
were associated with the thermal variations within these portions. The VT could be more
beneficial than RT in monitoring temperature of deeper portions of the female genital
tract in bovine. 相似文献
