Topic:Comparative Study
Comparative studies in equine research involve the systematic analysis of different horse breeds, management practices, or physiological responses to identify variations and similarities. These studies are instrumental in understanding how different factors influence health, performance, and behavior in horses. Common areas of comparison include genetic traits, nutritional requirements, disease resistance, and response to training. By evaluating these differences, researchers can develop targeted strategies for breeding, healthcare, and training. This page aggregates peer-reviewed research studies and scholarly articles that focus on the methodologies, findings, and implications of comparative studies in the context of equine science.
The concentration of blood sugar during starvation in the newborn calf and foal. Graham, Sampson and Hester (1941) observed that hypoglycaemia was a pathognomonic feature in a fatal disease of newborn pigs and subsequently made the important observation that
starvation alone could rapidly produce a similar syndrome (Sampson,
Hester and Graham, 1942). In contrast, Hanawalt and Sampson
(I947a) found that older pigs, weighing between 20 and 40 lb., were
resistant to a long period of starvation (24 and 28 days), the main
development of this resistance occurring during the first week of life
(Hanawalt and Sampson, I947b). Thus starvation from birth was
fatal in less than...
[Comparative studies on clearance determination in horses]. Results of comparative tests with several clearance methods on a total of 16 horses are reported.
The mean value calculated for endogenous creatinine clearance is 72.1±9.0, for total inulin clearance (from volume of distribution and elimination constant) 66.6±6.5 and for renal inulin clearance (with falling blood level and urine collection periods) 69.4±11.1 ml - min-1 - m-2.
The sodium clearance averages 0.12±0.09, the potassium clearance 38.1±12.4 ml - min-1 - m-2.
The results are discussed taking into account the different methods, and the possibility of using indirect clearan...
