Equine artificial insemination. The use and techniques of artificial insemination for horses in Germany over the last 30 years is described. Artificial insemination appears to produce pregnancy percentages equal to those from normal breeding methods and its continued availability under veterinary supervision is recommended in conditions where disease, disability or distance debar normal service.
Dropsy of the fetal sacs in mares: induced and spontaneous abortion. Eight cases of severe dropsy of the fetal sacs have been observed in mares. All were in multiparous mares whose ages ranged from five to 20 years and who were 7 1/2 to 10 3/4 months pregnant. Abortion started spontaneously in four cases and had to be induced in the remaining four by manual dilation of the cervix, rupture of the tough allantochorion and the siphoning off of 120 to 220 litres of allantoic fluid. The amnion was normal. Dystocia, due to uterine inertia, occurred in all eight cases, one hydrocephalic fetus needing fetotomy. All fetuses were alive at delivery although four were tera...

The selection of antibiotics. The usefulness of an antibiotic depends not only upon its antibacterial potency and spectrum but also on the prevalence of resistant organisms and the extent and severity of the adverse reactions to which it may give rise. Variations in formulation of the same compound are reflected in differences in bioavailability. These may be intentional, as in the development of long-acting preparations, but may also be unexpected following differences in drug purity, content and gastro-intestinal absorption. Individual and species differences in treated animals also result in variations in bioavailabilit...
Combined immunodeficiency with failure of colostral immunoglobulins transfer in foals. Foals with combined immunodeficiency (CID), a fatal genetic defect in the production of both B and T lymphocytes, are born without immunoglobulins and are unable to synthesise them. CID foals receiving immunoglobulins via the dam's colostrum may live up to four months of age. Those CID foals with failure of passive transfer (FPT) die at a much earlier age. The occurrence of CID is of value in studying passive transfer of immunoglobulins, as no confusion exists as to when passive transfer ends and active synthesis of immunoglobulins begins. A high correlation has been found between early foal d...
Lamellar corneal transplantation in the horse. Surgical correction of corneal opacities in horses has rarely been documented in detail and is still reported to be in the experimental stage. For this reason, studies of lamellar keratoplasty were conducted on the equine eye using a modified trephine with an adjustable inside quard for grafting of identical discs from the donor and the recipient cornea. Fourteen transplantations, seven with homografts and seven with heterografts, 15 and 9 mm in diameter, were performed. Sharp-edged, vertical, and regular outlined wound margins of the graft and host are essential for good adaptation and healin...
Serological study of an outbreak of paresis due to equid herpesvirus 1 (EHV-1). Six cases of paresis occurred in a Swedish stud with 48 mares and a stallion. Complement-fixation tests revealed a recent infection with EHV-1 in most horses of the stud. Serumneutralisation tests showed rapid antibody-titre increases during the course of the disease. This type of antibody response was interpreted as induced by reinfection or, possibly, recurrent infection. Two diseased mares were sacrificed. No virus could be isolated from their central nervous system (CNS), liver or spleen, but there is a presumptive evidence for the presence of an antigen specific to EHV-1 in the CNS and li...
Meningeal haemorrhage and congestion associated with the perinatal mortality of foals. A high frequency of meningeal lesions was found at autopsy in foals dying perinatally. Such lesions are considered an index of injury to the fetal central nervous system, from trauma and/or hypoxia during birth. Their incidence in the sample examined (26 foals) is similar to that observed in the perinatal mortality of lambs and calves.
Fluprostenol in mares: clinical trials for the treatment of infertility. Fluprostenol (ICI 81,008) is a 16-aryloxyprostaglandin, structurally related to PGF2alpha. It is a highly potent luteolytic agent, being effective in thoroughbred mares at a single intramuscular dose of 250 mug and having a wide margin of safety in this species. A total of 941 mares have been treated with fluprostenol in an international trial, for various forms of infertility associated with abnormal persistence of luteal function. These mares were selected for treatment on the basis of clinical examination and 760 (approximately 80 per cent) responded fluprostenol by showing oestrus within s...
Observations on growth plates in limbs of foals. Observations were made which may be related to growth plate disorders. They included irregularity and thickening of the growth plate bridging of the plate by bony spicules, distortion of the plate adjacent to foci of fusion, and metaphyseal lipping. These observations are very similar to those found in "epiphysitis." The question had to be asked, where these normal foals or did they have sub-clinical "epiphysitis"?
