The pH level in horses is a measure of the acidity or alkalinity of various bodily fluids and tissues, which can influence numerous physiological processes. In horses, pH balance is essential for maintaining metabolic functions and overall health. The pH of blood, for example, is maintained within a narrow range through various buffering systems to ensure optimal cellular activity and enzyme function. Deviations from the normal pH range can indicate underlying health issues, such as metabolic disorders or respiratory problems. This topic encompasses peer-reviewed research studies and scholarly articles that explore the regulation, measurement, and implications of pH levels in equine biology, including their impact on performance, digestion, and disease states.
ALLFREY V, MIRSKY AE.It has been found that many animal tissues contain "acid" desoxyribonucleases with pH optima near 5.2. A chemical method for the determination of this activity is described. The pancreatic desoxyribonuclease crystallized by Kunitz and shown to have a neutral pH optimum occurs in the pancreas together with the "acid" enzyme, but only the "neutral" enzyme occurs in the pancreatic juice. The ratio of "neutral" to "acid" DNAase activities in the pancreas is greater than 200, but in all other tissues examined there is no appreciable concentration of the neutral enzyme. It is concluded that neutral ...
Octaviano JI, Alonso MA, Boakari YL, Gomes V, Mori CS, Fleury PDC, Fernandes CB.Monitoring equine parturition effectively is essential for preemptive intervention in periparturient issues and ensuring the overall well-being of both mares and foals. However, its implementation in breeding farms is challenging due to variable gestational lengths and nocturnal births. Predictive techniques have the potential to streamline the monitoring process, reduce labor intensity, and minimize costs. Research on foaling prediction in mares carrying mule or equine clone fetuses is scarce. Therefore, this study aimed to comparatively analyze foaling prediction parameters in mares pregnant...
Coletta M, Zingale GA, De Simone G, De Sanctis G, Quadrotta V, Polticelli F, Ascenzi P.Mini-myoglobin (mini-HH-Mb) is a proteolytic fragment of horse heart myoglobin (HH-Mb) comprising residues 32-139, grossly corresponding to the central exon of the HH-Mb gene, which encodes residues 31-105. Unlike HH-Mb, which displays a single exponential for both CO association and CO dissociation kinetics, mini-HH-Mb shows a biphasic kinetic behavior for both processes, indicating the presence of at least two distinct conformations which are in a very slow (or no) equilibrium with each other. Between pH 2 and 12, CO association to both species of mini-HH-Mb shows two proton-linked transiti...
