[Determination of progesterone levels in the milk of mares: a useful aid in the diagnosis of early pregnancy]. The concentration of progesterone in milk was determined in 327 mares to establish pregnancy in an early stage (sixteen days or more). The 5 ng/ml-level of progesterone as a threshold in the EIA-system used resulted in a very useful aid in the diagnosis of early pregnancy in mares. The results of testing were not in accordance with the confirmed reality in fourteen out of 327 mares (4.3 percent). The result of the test was false non-pregnant in five mares (1.5 percent) and false pregnant in nine mares (2.8 percent).
[Frontal sinusitis in a horse with a neurological complication]. The case of a horse affected with frontal sinusitis, in which neurological complications occurred following trepanation, is reported. The previous history of the animal as well as the clinical, radiological and pathological findings are discussed.
[Periodic uveitis in horses]. The aetiology, clinical symptoms and treatment of equine periodic ophthalmia are discussed. Particular attention is paid to the possible role in aetiology of Onchocerca cervicalis microfilariae. Corticosteroids and atropine are the most important therapeutic drugs.
[The treatment of podotrochilosis with oral anticoagulants. An instruction insert desired]. The anticoagulant, warfarin, has been reported to be effective as treatment for navicular disease in horses. Since other forms of treatment for this disease are palliative, this new anticoagulant therapy has become widely employed. Despite the fact that initiation of anticoagulant therapy is relatively simple, attending veterinary practitioners should be aware that careful monitoring of this therapy is required for both safety and efficacy. Navicular disease is an example of equine thrombotic disease, and the goal of warfarin therapy is the prevention of new thrombus formation, while at the sa...
[An undesirable drug interaction in horses? Complications which can occur during the administration of coumarin derivatives and phenylbutazone]. A study of the literature was done because of questions asked in a court of justice concerning possible poisoning in a jumper, resulting from administration of both phenylbutazone and a coumarin derivative within a particular period. In view of the mechanisms of action and the pharmacokinetic characteristics of the agents, these forms of combined treatment are also highly inadvisable in horses.
[Progesterone in mare’s milk: suitable for early pregnancy detection?]. The concentrations of progesterone in milk were determined in twenty-one mares to establish a diagnosis of pregnancy in an early stage (15-19 days). Progesterone levels varied from 0.0 to 4.2 ng/ml in nine non-pregnant mares and from 6.7 to 30.0 ng/ml in twelve pregnant mares. Progesterone levels were determined by an enzyme-linked immunosorbent assay (ELISA).
[Comparison of the efficacy of ivermectin in injectable form and as a paste in horses]. A comparison was made of the efficacy of Ivermectin administered as an injection and as a paste. Fourteen horses which were naturally infected with small strongyles were divided into three groups. Animals of group 1 received an injection of 5 ml Ivermectin, equivalent to 500 kg bodyweight, horses of group 2 received one injector with Ivermectin as a paste (for 500 kg body weight), a third group remained untreated as a control. Faecal examinations and larval cultures on the day of treatment and 14, 28 and 42 days later showed that both injection and paste had a 100 percent efficacy against matu...
[Extrahepatic cholestasis due to pancreas fibrosis in a trotter]. A trotter stallion showing symptoms of emaciation was suspected of disease of the liver associated with cholestasis in view of clinical symptoms (poor appetite, sluggishness, jaundice and oedema) and the results of examination of the blood (increased concentrations of gamma-glutamyl, transpeptidase, sorbitol dehydrogenase, alkaline phosphatase, aspartate aminotransferase and markedly increased conjugated bilirubin). A specimen removed at biopsy of the liver revealed the presence of portal fibrosis and severe cholestasis. At autopsy, it was found that very extensive fibrosis of the pancreas (pr...
[Neurological disorders caused by equine herpesvirus type 1 and cauda equina neuritis in horses]. The differences in aetiology, symptomatology, pathomorphology, diagnosis and therapy between the nervous form (paralytic form) of Equine Herpes Virus, type 1, and Neuritis Caudae Equinae are reviewed. The conclusion is that in most cases it is possible to differentiate between these two clinical syndromes.
[Plasma fibrinogen as a parameter of the presence and severity of inflammation in horses and cattle]. Determination of the plasma fibrinogen concentration was found to be particularly useful in detecting inflammatory diseases. The highest levels were observed in inflammatory lesions of serous surfaces and in endocarditis. Plasma fibrinogen levels correlated with the severity of the disease: levels of 1,000 mg per 100 ml or more reflected a prognosis ranging from poor to bad.
[Chronic purulent maxillary sinusitis in horses]. The surgical treatment of eighty-nine horses and ponies suffering from chronic empyema of the maxillary sinus is reported. Treatment consisted in trephination and drainage of the sinus involved in thirty-six animals; the affected teeth were removed at the same time in fifty-three animals in which sinusitis was caused by an alveolitis. The recovery rate was seventy-five per cent in group one and seventy per cent in group two. Postoperative treatment is also reported and attention is paid to complications which may occur during and after surgery.
[Twin pregnancy in mares]. A number of findings on twin pregnancies in mares recently reported in the literature are evaluated in the present paper. From these findings it emerges that twin pregnancies in mares very rarely develop from a synchronous (less than 2 days apart) double ovulation but rather from an asynchronous (much greater than 2 days apart) double ovulation. The significance of these findings in daily practice is pointed out. Moreover, it was found that in more than 50 per cent of the cases in which twin pregnancies had been diagnosed about day 20, one embryo had died by day 36. From this fact it is conclu...
[The use of linear-array real-time echography in veterinary obstetrics and gynecology]. For the past few years, two-dimensional diagnostic ultrasound methods have become available to veterinary medicine. In particular, linear-array real-time ultrasound would appear to be a very suitable diagnostic tool in the examination of the female genital organs of domestic mammals. The principles of this technique and the equipment available are described, and particular attention is paid to the method by which a diagnosis of pregnancy may be established in various animal species. In dogs and goats shaving will have to be done before the sound-transmitting/receiving transducer can be placed ...
[Roentgenological aspects of polyarthritis in foals]. Radiographically, joint ill in foals is subdivided into four different types: Type P - osteomyelitis in the meta- and/or epiphysis adjacent to the physis. Type E - osteomyelitis in the epiphyseal subchondral bone. Type S - synovitis confined to the joint itself. Type T - osteomyelitis in the small tarsal bones. The radiographical features corresponding with the different types, the relationship between the radiological, pathological, bacterial and clinical findings, and the recommended radiographic procedure are discussed in detail.
[Meconium constipation in foals]. Meconium constipation is observed in a number of foals during every foaling period. The literature on the clinical picture, methods of treatment and complications, is reviewed in the present paper. In addition, the cases of seventy-five foals are reviewed, in which meconium constipation was suspected and which were submitted to the Internal Disease Department of Large Animals during the period from 1972 to 1982. The clinical picture was found to be due to another disorder in nine cases. Treatment with castor oil and alcohol resulted in discharge of the meconium in fifty-eight cases. Complicati...
[Various aspects of lactate production and disappearance in trotters during exertion]. Venous lactate concentrations were determined in standard-bred trotters following exercise of varying intensity to obtain a useful parameter in determining the working capacity of horses. After standard exercise, well-trained horses produced less lactate than did inadequately trained horses. During the post-exercise resting period, lactate disappeared faster from the blood in well-trained horses and young lightly trained horses than it did in poorly trained horses. Steady-state training resulted in lower lactate levels than those recorded after racing, whereas interval training resulted in the...
[An inventory of the castration of stallions based on a survey among Dutch veterinarians]. To gain an insight into the procedures adopted in castrating stallions in the Netherlands, a questionnaire was sent to 670 Dutch veterinary practitioners. The 176 veterinary practitioners who replied performed 1850 castrations. Castration of the recumbent horse was preferred by 88 per cent of the veterinary surgeons. Fifty per cent preferred the open method of castration and 44 per cent the half-closed technique. A local anaesthetic was given by 65 per cent of the practitioners; 84 per cent administered antibiotics in an attempt to prevent wound infection. Postoperative complications were obse...
[Experiences with half-closed castration in stallions]. The half-closed method of castration involves ligation of the spermatic cord enclosed in the vaginal tunic, the testicle itself lying outside the opened vaginal tunic. Of 497 horses and ponies admitted to the Department of Large Animal Surgery and castrated using this technique, 68.6 per cent recovered without complications. Although the most serious postoperative complications such as intestinal eventration and haemorrhage of the spermatic cord may be reduced to a minimum by this approach, normal healing cannot be guaranteed under the circumstances in which this method was used.
[Primary closure of the scrotal wound in the castration of stallions]. A method of castration in stallions is reported on, in which primary closure of the wound caused by castration was attempted. Primary wound-healing occurred in 90 per cent of 110 stallions showing normally descended testicles, whereas this proportion was 97.4 per cent in thirty-eight unilaterally cryptorchid stallions in which the normally descended testicle was removed using the method described. It is concluded that the present method of castration will only be successful when surgery is carried out under strictly aseptic conditions.
[The treatment of a lung worm infection in ponies with albendazole (Valbazen)]. A report on infection with Dictyocaulus arnfieldi in a number of ponies and one horse in which complete clinical recovery was obtained following treatment with albendazole (Valbazen), administered by oral route at a dosage of 25 mg/kg of body weight twice daily for five days.
[Prevention of Strongylidae infections in the horse]. Proceeding on the epidemiology of Strongylidae infection in horses, the effects of combined anthelmintic treatment and moving to non-contaminated pasture in July were studied during 1981 and 1982. This strategy for control was found to be effective as was shown by faecal examination, pasture larval counts and post-mortem worm counts. No significant contamination or worm infection developed in the group of treated ponies moved to celan pasture after July 1. On the permanently grazed pasture the same pattern of infection developed as on the pasture where up to July 1 ponies and subsequently shee...
[The value of blood progesterone determination about 18 days post ovulation for pregnancy testing in mares]. The reliability of determination of the plasma progesterone level within approximately eighteen days after ovulation in the pregnancy diagnosis of mares is examined in the present study. Studies were done in seventy-five mares, a number of which were served or inseminated during several cycles so that a total number of eighty-seven blood samples were obtained. On the analogy of other authors, the progesterone level above which mares were believed to be pregnant and below which they were assumed to be non-pregnant, was set at 2 ng/ml. The twenty-five mares in which the level was below 2 ng/ml. ...
[A pony with “false” colic]. Report on the case of a pony with colic submitted a to the department of internal medicine. However, the animal was found to be affected with dilatation of the oesophagus which had given rise to acute pleurisy resulting from rupture of the wall of the oesophagus. The diagnosis was established after death.
