Topic:Animal Health
Animal Health encompasses a broad range of topics focused on maintaining and improving the well-being of equine species. This field addresses various aspects of horse care, including disease prevention, diagnosis, treatment, and management of health conditions. Key areas of interest include equine nutrition, vaccination protocols, parasite control, dental care, and the management of chronic conditions such as laminitis and colic. Additionally, animal health research in horses investigates the impact of exercise and training on physical health, the role of genetics in disease susceptibility, and the development of new therapeutic approaches. This page compiles peer-reviewed research studies and scholarly articles that explore the latest advancements, challenges, and best practices in preserving and enhancing the health of horses.
Training and exercise change respiratory properties of blood in race horses. Effects of training and exercise on blood respiratory properties were investigated in standard-bred race horses. Training caused an increase in the circulating O2 capacity at rest from 18.4 to 21.0 vol%, and in the O2 capacity during exercise from 24.9 to 30.3 vol%. An increase in the in vitro oxygen affinity [P50(PH 7.4, 37.9 degrees C)] of about 2 mm Hg correlated with a decrease in the red cell concentration of 2,3-diphosphoglycerate (DPG) from 6.35 mM-1-1(E), erythrocytes. Trained horses also showed an acute lowering of the red cell DPG concentration after maximal exercise. The physiologic...
Regulatory veterinary medicine in a changing environment. There is an increasing need for the veterinary profession to meet the new challenges brought about by increased and intensified livestock production. These challenges consist of control and eradication of diseases, the humane treatment of animals and the prevention of transmission of disease from animals or animal products to man. Examples are given of the contribution which regulatory medicine activities have made to the prevention/control/eradication of screw worm, foot-and-mouth disease, Venezuelan equine encephalomyelitis, Newcastle disease, bovine brucellosis, hog cholera, and certain oth...
Anoestrous conditions in the mare, their diagnosis and treatment. The condition of anoestrus in the mare is described and the various causes of this syndrome are discussed. A regimen for examining systematically the clinically anoestrus mare is proposed, and methods of treatment are suggested.
Some haematological and biochemical parameters in race horses in Hong Kong. Haematological and biochemical values were determined in 2 groups of flat-race horses, which were trained on the same track in Hong Kong. The first group comprised 217 horses (435 blood samples) from various training strings. The second group, 66 horses (309 blood samples) were from one string kept under similar managemental conditions, but given salts by stomach tube 8 hours before blood sampling. Both groups were sub-divided to show the efs, thus confirming work by other authors. The lower haematological values in the group of horses given salts were discussed and the effect of water retenti...
[Long-term therapy using horse anti-dog lymphocyte globulin without sensitization against horse protein]. Eight mongrel dogs received a standard daily i.v. infusion of 20 mg/kg b.w. deaggregated horse-anti-dog-lymphocyte-globulin (ALG) and additional prednisolone (1 mg/kg b.w. daily i.v.) over a maximum period of 82 days following pretreatment with deaggregated normal horse IgG. No sensitization against horse protein was observed during therapy of afterwards as proved by lack of humoral antibodies against horse antigens, maintained lymphopenia, good compatibility, longterm prolongation of xenogeneic skin graft survival (85.6+/-20.6 days, n=8' untreated controls 12.5+/-1.3 days, n=4) and longterm s...
Effect of prostaglandin analogue on progesterone-treated pony mares during early pregnancy. Seven Welsh pony mares (9 pregnancies) received either 50 mg, 100 mg or 150 mg progesterone on alternate days, starting on day 21 of gestation. All but 2 pregnancies failed following prostaglandin administration on day 27. Although both mares were receiving the 150 mg progesterone dose rate, this treatment was not consistently successful in preventing pregnancy failure after prostaglandin administration.
Exercise studies in horses: 2. The cardiac response to exercise in normal horses and in horses with chronic obstructive pulmonary disease. The relationship of velocity (v) to heart rate (HR)and of kinetic energy (KE) to heart rate, were investigated in 6 normal horses and in 6 horses with chronic obstructive pulmonary, disease (COPD). Radiotelemetry was used to determine the heart rate while subjects were ridden on a 400m track. Velocity was measured by stop-watch between 2 markers 50 m apart at the end of the track. Kinetic energy was calculated from the formula KE =1/2 Mv2, where M = mass of horse, rider, saddle and bridle (KG) and V = velocity (metres per second). In all subjects, the relationship of velocity to heart rate was...
Isolation and properties of prophospholipase A2 and phospholipase A2 from horse pancreas and horse pancreatic juice. Two phospholipases A2 (EC 3.1.1.4) with different isoelectric points have been isolated from horse pancreas in high yield (880 mg/kg tissue). From pancreatic juice the more acidic species was isolated as the sole phospholipase A2. Upon tryptic activation the zymogens release a hepta- and pentapeptide, respectively from the N-terminal part of the protein giving rise to the formation of one single enzyme with a specific activity higher than that of pancreatic phospholipases A2 from other mammalian species. Horse phospholipase A2 differs from the porcine and bovine enzymes with respect to amino a...
Laminitis in the horse. Much has been written on laminitis and its treatment over the past 200 years. This article makes a brief review of the practical essentials of the disease and considers some of the recent trends in therapy. Knowledge of the pathogenesis and aetiology of equine laminitis is still very incomplete but recent work in the United States by Coffman and his colleagues has been particularly productive.
Recent developments in air transportation of farm animals and horses. This paper deals with some recent developments in the air transportation of cattle, sheep, pigs and horses and comments on the factors involved which influence the results.
