On the watering of horses: a review. The literature published over the last 150 years provides confusing and often conflicting advice on the ideal way to water horses. Many of the problems associated with watering appear to be caused by either mismanagement or ignorance. An obvious way to prevent trouble is to provide adequate water at all times when a horse is at rest and to allow sufficient opportunity to drink while working.

Isoelectric focusing of horse serum esterase isozymes and detection of new phenotypes. A new method for separating the isozymes of horse serum esterase is described. The improved resolution has enabled us to detect several previously undescribed phenotypes. This method has also been used to detect two different apparently 'silent' alleles.
Diagnosis of equine neurologic problems. This is a review of the more common diseases of the spinal cord and various areas of the brain of horses. The results of a two and one-half year study of spinal cord disease are emphasized. After a description of the lesion the salient clinical signs are described and the features that differentiate them from other similar diseases. In the seminar, films of case and slides of lesions will be shown to document these diseases.
Close linkage between the albumin and Gc loci in the horse. Evidence for close linkage between the structural loci for albumin and Gc protein in the horse was presented. A recombination frequency (c) of 0.009 +/- 0.006 (95% confidence limits: 0.001 less than c less than 0.032) was estimated. These results were based on a study of a large sire family comprising 223 offspring from informative matings. No evidence of linkage disequilibrium was observed in one horse population studied.
The development of a radio-stethoscope for use in the horse at rest and during exercise. The development of a radio-stethoscope for horses is described. The equipment consisted of a sound transducer applied to the skin adjacent to the trachea and a radio transmitter attached to the saddle. The signals emitted were detected by telemetry and recorded on a magnetic tape-recorder. The recorder incorporated a monitor earphone so that sounds could be reproduced at the time of recording. The frequency response obtainable ranged from a few Hz to 4 KHz. This technique provided an objective means of studying the respiratory sounds generated during exercise although absolute values could not...
Proprioceptive innervation of the external cremaster muscle of some domestic mammals. The proprioceptive innervation of the external cremaster muscle of some domestic animals was studied. Muscle spindles and tendon organs with their well-known features were found, but this finding was uncommon and unexpected in the investigated animals. For this reason, we believe that there is no relationship between the presence of these proprioceptors and the cremasteric reflex.
Common and species-specific esterases of Equidae–IV. Horse of przewalski, onager and Zebra hartmannae. 1. Among several species of Equidae only E. przewalskii possesses a serum esterase identical with that of E. caballus. 2. The esterases of Hemionidae differ slightly from that of domestic horse by electrophoretic migration and by antigenic structure. 3. Zebras (grevyi, burchelli) appear devoid of this component but Z. hartmannae possesses an esterase of high enzymatic activity, differing notably from that of horse by electrophoretic and antigenic properties.
The ‘normal range’ and precision of phytohaemagglutinin-induced equine lymphocyte transformation in vitro. Data are presented on lymphocyte transformation by phytohaemagglutinin in 20 normal horses. The logarithms of transformation ratios were found to have an approximately normal distribution, giving (for the transformation ratios themselves) a geometric mean of 23.6, a range of 1.92 to 97.3, and an estimated 95 per cent tolerance interval of 1.1 to 488. Analysis of variance on the logarithms of the transformation ratios gave a coefficient of variation of 140 per cent of the transformation ratios themselves for the variation between horses; whereas the coefficient of variation between duplicate sa...
Comparative studies on blood serum alpha-L-fucosidases from several mammalian species. 1. Peripheral blood serum alpha-L-fucosidases have been studied from various mammalian species: Sus scropha var domestica L. (pig), Capra hircus L. (goat), Bos taurus L. (bull, races Morucha and Charolais), Equus caballus L. (horse) and Equus asinus L. (donkey). 2. Fluorimetric and spectrophotometric procedures were used for determination of alpha-L-fucosidases. 3. alpha-L-Fucosidases were more active towards fluorescent substrates than towards chromogenic substrates. 4. pH optima values of the enzymes are: (A) 5.5 for sera from all above-mentioned species when fluorescent substrates were empl...
[Hippotherapy–a supplementary treatment for motion disturbance caused by cerebral palsy (author’s transl)]. Neurodevelopmental treatment according to Dr. K. and B. Bobath can be supplemented by hippotherapy. At proper control and guidance, an improvement in posture tone, inhibition of pathological movement patterns, facilitation of normal automatical reactions and the promotion of sensorimotor perceptions is achieved. By adjustment to the swaying movements of the horse, the child feels how to retain straightening alignment, symmetry and balance. By pleasure in this therapy, the child can be motivated to satisfactory cooperation and accepts the therapy horse as its friend. The results of hippotherapy...
Maternal recognition of pregnancy and immunological implications of trophoblast-endometrium interactions in equids. Fertilized eggs reach the uterus of the mare by the sixth day after ovulation whereas unfertilized eggs remain lodged in the fallopian tubes for many months. However, embryo removal studies indicate that the fetal message for luteal maintenance in the pregnant mare is not transmitted until Days 14-16. The equine endometrial cups comprise a series of small, ulcer-like endometrial outgrowths which are present in the pregnant horn of the uterus between 40 and 150 days of gestation. Each cup consists of a discrete colony of large, gonadotropin-secreting, trophoblast cells derived from a specialize...
Bending properties of cortical bone of the horse. Bending properties of samples of cortical bone taken from the cranial, caudal, medial, and lateral quadrants of the midshaft of the radius, femur, and metacarpus of 12 ponies, 18 months old, were determined by 4-point loading at a rate of 10 mm/minute. The elastic modulus for all samples was between 16.2 and 20.2 GN/m2, and the ultimate breaking strength, between 204 and 255 MN/m2. There was greater variation in these properties between bone quadrants than between bones. Samples from the cranial and medial quadrants of both femur and radius were stiffer and had greater ultimate breaking streng...
A survey of biting flies attacking equines in three states of the southwestern United States, 1972. A survey of biting flies in the southwestern United States resulted in the recovery of 34 species as they attacked equines. The geographic distribution of each species at 15 sites and the abundance of attacking flies were used to determine that 22 species commonly attack equines. Culicoides variipennis (Coquillett) was the most common species collected; it was recovered at 12 sites and comprised the highest percentage (29.8%) of the total survey catch for all species collected. The next 2 most common species were Psorophora columbiae (Dyar & Knab) and Aedes vexans (Meigen). C. variipennis was ...
Germ cell proliferations in the fetal horse ovary. During the 340 day pregnancy of the horse, the germ cells in the fetal ovary showed a meiotic prophase which began in days 60-70 and might be prolonged after day 200. Three or four successive oogonial mitotic proliferations passed into the meiotic prophase but the great majority of the oocytes first involved degenerated, and no appreciable numbers of primordial follicles were left behind. At 150 days of pregnancy and again at 197 days, oocytes in early meiotic stages filled the ovarian cortex. Primordial follicles were present, but rare. As the prophase gradually came to an end, groups of oocy...
