Effect of Daily Administration of a Rehydrating Supplement to Trotter Horses
No full textAn interesting aspect of athlete horse management is connected with the effects of the profuse sweating required to maintain body temperature. The various aspects related to thermoregulation are discussed, with special reference to water and electrolyte losses. The effects of the sporadic or systematic administration of rehydrating supplements were examined in four trotters aged 3-4 years used in competitions. The horses performed three exercise tests simulating a 2,000 m race. At the time of the second and third test, the control diet (Test 1) also included a rehydrating supplement which subjects had been receiving for one day (Test 2) or 12 days (Test 3). Subjects were weighed (at rest, after the race and 24 h later) and blood samples were collected (at rest, immediately after the race; 20 min after the race, and 24 h thereafter). Changes in weight and in blood parameters (pH, PCV, lactic acid, Na+, K+, Cl-, Lactate dehydrogenase (LDH), Aspartate aminotransferase (AST), Glutathione Peroxidase (GSH-Px), Antioxidant Power (AOP)) indicate a favourable effect of rehydrating supplements on muscle condition, especially when administered systematicall
Pre-foaling period in Trotter mares – 2: variations of protein fractions in pre-colostrum secretion
No full textMare has a diffuse epitheliochorial placenta that does not allow the transplacental passage of maternal antibodies to the foetus. As a consequence, newly-born foals are immunologically dependent on the absorption of colostral maternal immunoglobulins (Ig). Therefore, the newborn foal should immediately suckle an adequate quantity of colostrum to reach an haematological IgG concentration of 400 mg/dl which prevent the occurrence of Failure of Passive Transfer (FPT), disease which can be fatal to the foal (Jeffcott, 1972; Curadi and Orlandi, 1998)
