Topic:Veterinary Science
Veterinary science and horses encompass the study and application of medical, surgical, and therapeutic practices to maintain and improve the health and welfare of equines. This field addresses a wide range of topics, including disease prevention, diagnosis, and treatment, as well as nutrition, reproduction, and behavior. Research in veterinary science for horses often involves understanding the pathophysiology of equine-specific diseases, developing advanced diagnostic techniques, and improving treatment protocols. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary science related to horses, providing insights into the latest advancements and methodologies in equine healthcare.
Some serological reactions to “brucella” antigen in the horse. Seventy-three samples of serum, from 69 horses and one zebra, were subjected to the Rose Bengal Plate, serum tube agglutination, complement fixation, and anti-equine globulin (Coombs') tests for brucellosis. Fifty-one of the samples, from 48 horses, were submitted by practising veterinary surgeons; of these, 22 samples were associated with clinical conditions which might have been due to brucellosis. Fourteen samples were from healthy horses known to have been in contact with infected cattle, and six were from horses which were known not to have been exposed to brucellosis. More reactions at a...
A scanning electron microscopic study of platelets of certain animal species. Comparative morphology of platelets of the dog, cat, cow, horse, sheep, and goat was studied with the scanning electron microscope and was found generally similar. Most of the platelets were slightly biconvex of flat with relatively smooth surface and even contour. Some of these platelets had few short marginal filaments, oriny protuberances on the surface. A small number of platelets exhibited surface irregularity and few long pseudopods which were thought to result from platelet activation during the processing of blood. The number os such irregular platelets increased in stored blood and in...
Heat stability and reactivation of mare milk lysozyme. Mare milk and aqueous solution of mare milk lysozyme were incubated for variable times between 30 C and 100 C at pH 3, 6, or 9. Lysozyme activity was stable at acid and neutral pH and labile at alkaline pH. Some of the results show the existence of a reactivation process in mare's milk and in aqueous solution. reaching 30 to 40% after incubation of the aqueous solution at 4 C for 20 days at pH 3 or 6.
Morphology of epididymal spermatozoa in the ass (Equus asinus) and stallion (Equus caballus). The morphological changes which take place in the sperm during their passage
through the excurrent ducts have been studied in the bull (BRANTON and SALISBURY
1947; HANCOCK 1955; BAILY and SMITH 1958; AMANN and ALMQUIST 1962; GUSTAFSSON and CRABO 1971 ; RAO 1971) and boar (GUSTAFSSON, CRABO and EINARSSON 1970).
Such knowledge is of major importance in understanding the origin and significance
of the different sperm abnormalties as well as providing the basis for proper appraisal
of semen picture and devising useful spermiograms.
The aim of the present work is to study the morphological ch...
Recovery of procaine from biological fluids. A published method for the recovery of procaine from human plasma using 5M NaOH gave very poor recoveries. Investigation showed that under the recommended extraction conditions procaine was rapidly hydrolysed. Extraction into benzene of samples buffered to pH 9.0 with borate buffer allowed essentially 100% recovery of procaine from equine plasma and urine.
Comparison of the myoglobin of the zebra (Equus burchelli) with that of the horse (Equus caballus). The tryptic and peptic peptides from the myoglobin of the zebra (Equus burchelli) have been compared with those obtained from the myoglobin of the horse (Equus caballus). No differences in the myoglobin were found between these two species.
Bile secretion in ponies with biliary fistuals. Surgically placed bile duct cannulas allowed collection of secreted bile from nonanesthetized ponies. UNINTERRUPTED ENTEROPHEPATIC CIRCULATION WAS PERMITTED BETWEEN COLLECTIONS. Deleterious effects of cannulation were not observed. Average bile flow was 18.6 plus or minus 1.72 (standard error) mul/minute/kg, bile acid excretion was 0.179 plus or minus 0.0212 mumole/minute/kg, and bilirubin excretion averaged 1.22 plus or minus 0.136 mug/minute/kg.
Identification of O-cetylated N-acylneuraminic acids by mass spectrometry. A number of O-acetylated N-acylneuraminic acids, isolated from submandibular glands of cow and horse and from horse erythrocytes, have been characterized by mass spectrometry. On the basis of the typical fragmentation patterns of the pertrimethylsilyl derivatives of the methyl esters of the compounds, they were identified as 4-O-acetyl-, 9-O-acetyl-, 4,9-di-O-acetyl-, and 7,9-di-O-acetyl N-acetylneuraminic acid, and 4-O-acetyl-and 9-O-acetyl-N-glycolylneuraminic acid.
The use of ultrasonic energy to vaporize anaesthetic liquids. Ultrasonic energy, provided by a commercially available water vaporizer, was used to vaporize methoxyflurane, halothane, and chloroform. The vaporizer was placed directly in the respiratory line, and the anaesthetic liquid was vaporized one drop at a time. Anaesthesia was maintained for periods up to 6 hr in horses, ponies, calves, sheep, dogs, and one pig. This method of vaporizing liquids is applicable to a wide variety of anaesthetics. It is easily controlled, and the same vaporizer can be used with a wide range of sizes of subjects. The vaporizer can be placed directly in the respiratory c...
[Sterols of horse erythrocytes]. Sterols of the whole erythrocytes, hemoglobin, membranes and their protein fractions were studied. Erythrocytes and their components were established to contain, besides cholesterol, other substances of the sterol nature. Cholesterol, 7-dehydrocholesterol and other substances of the cholesterol series are practically completely linked with the lipoproteid fractions of the erythrocyte membrane whereas all sterols found in the native erythrocytes in negligible amounts are bound with hemoglobin.
