The effectiveness of commonly used parasiticides decreases due to the drug resistance developed by many organisms. Therefore, application feed additives possessing antiparasitic properties may be helpful in limiting burden parasites. aim this research was evaluate parasitological coefficients for endoparasites regularly dewormed Arabian horses and Thoroughbreds, fed on a basal diet oat muesli w...

and heart have shown that glucose uptake, glycogenolysis, glycolysis and pyruvate oxidation are partially inhibited by the oxidation of fatty acids (Jansson and Kaijser 1984, Rändleet al. 1963). Extracellular alkalosis also affects blood lactate concentration by in creasing the magnitude and rate of lactate efflux from muscle during contraction (Mainwood and WorselyBrown 1975, Spriet et al. 19...

Egypt is anticipated to be potentially influenced by the global climate warming. Therefore, the current study aimed to evaluate the influence of age on the fertility potential of Arabian stallions during summer breeding months. Arabian horses grouped according to their age into three groups, each involved six stallions: young (5-6 years), middle (11-12 years) and old (15-20 years) age gro...

Stable isotope infusion methods have not been extensively used in horses to study protein metabolism. The objectives were to develop infusion and sampling methodologies for [1-(13)C] phenylalanine and apply these methods to determine whether the addition of supplemental amino acids to a control diet affected whole-body phenylalanine kinetics in mature horses. Arabian geldings were studied using...

The existence of the Hucul horse on Romanian territory has been documented from the very distant past; today Hucul is a unique breed that is part of the FAO Program for the Preservation of Animal Genetic Resources. We compared Hucul with several primitive European and Asiatic breeds in order to elucidate the origin of these horses. We analyzed a 683-bp mitochondrial DNA (mtDNA) D-loop fra...

The aim of the study was to define the influence of the selected factors (gender, age, transportation time, riding distance and air temperature during the ride) on the cortisol secretion and finding a correlation between the hormone level and the horses' sport results (veterinary parameters and the ride route parameters). The research was performed on 38 Arabian pure breed horses taking part in...
