Topic:Biochemistry
The study of biochemistry in horses encompasses the chemical processes and substances that occur within equine organisms. This field investigates the molecular interactions and pathways that are fundamental to horse physiology, including metabolism, enzyme activity, and genetic expression. Key areas of interest include the examination of metabolic disorders, nutrient absorption, and the biochemical basis of muscle function and energy production. Researchers utilize biochemical analysis to understand health and disease mechanisms in horses, contributing to the development of diagnostic tools and therapeutic strategies. This page gathers peer-reviewed studies and scholarly articles that explore various biochemical processes and their implications for equine health and performance.
Free erythrocyte protoporphyrin in the horse. Free erythrocyte protoporphyrin was estimated in 166 Thoroughbred horses and the mean value was found to be 4o vg.Poo ml. packed cells. Signifi-cantly lower haemoglobin concentrations were found in 21 horses whose erythrocyte protoporphyrin concentration was 7o p.g.lioo ml. packed cells or greater.
Effects of potassium in a purified equine diet. The effects of 0.2, 0.4, 0.6, 0.8, 1.0 and 1.2% potassium, as K2CO3, in a purified diet were studied in orphaned foals of mixed breeding ranging in age from 11 to 57 days. Observations regarding feed intake, rate of gain, packed cell volume (PCV), erythrocyte counts (RBC), hemoglobin (Hb), leukocyte counts (WBC), and serum Na, K and Fe were made. Consumption of the 0.2% K diet after 8 days was inadequate to support growth. The foals consumed the 1.0 and 1.2% K diet at significantly higher rates (28.8 and 27.5 g/kg foal per day, respectively) than the 0.4% K diet. Rates of gain of foals fed 0.4...
Phospholipid composition of Venezuelan equine encephalitis virus. Phospholipid analyses of Venezuelan equine encephalitis virus showed that virus propagated in L-cell monolayers had a higher sphingomyelin content and a lower phosphatidylcholine content than virus grown in chick fibroblast monolayers. Virus of L-cell origin also was found to possess greater thermal stability than virus derived from the chick fibroblast cell.
Calcium metabolism in ponies fed a high phosphorus diet. Calcium metabolism was studied by combined metabolic balance and kinetic methods in four young Shetland ponies fed a diet containing 0.4% calcium and either 0.2% or 1.2% phosphorus in a replicated 2 × 2 Latin square experimental design. Phosphorus retention and plasma phosphorus concentration were greater when the ponies were fed the high phosphate diet. The high phosphate intake decreased calcium absorption, urinary excretion and retention but increased total and endogenous fecal calcium excretion. However, the ponies were in positive calcium balance when fed either the basal or high phospha...
[Histochemical and ultrastructural study of the acid phosphatase, alkaline phosphatase, and adenosine triphosphatase contents in the pars proventricularis epitheiium of the horse stomach]. Summary. The activities and localization of a lysosomal acid phosphatase and of a Mg++- and Ca++-activated ATPase were shown in the pars proventricularis epithelium of the horse stomach using cytochemical methods and the light and electron microscopes. Activity of the non-specific alkaline phosphatase was exclusively demonstrated on the subepithelial vessel loops of the papillae occultae.
The activityof ATPases gradually decreased from the stratum basale to the stratum super- ficiale. Reaction intensity was optimal after 45 rain and did not increase further. An increase of the Mg++-activated ...
Metabolism of immunoglobulin-G in the horse. The metabolism of immunoglobulin classes has been closely examined in several animal species. Although the horse has received much attention in experimental and applied immunology there seems to be little information available on immunoglobulin kinetics in this species. The present report describes the metabolism of equine IgG in 4 healthy, normoimmunoglobulinaemic horses, in 1 horse with hyperimmunoglobulinaemia and in 1 horse with relatively low immunoglobulin levels.
