This page compiles peer-reviewed research studies and scholarly articles that explore the composition, digestion, and impact of different dietary components on equine health and performance.
Do Polish Konik Horses Find Soaked Hay to Be Palatable? Frequently, equine diseases necessitate the moistening or soaking of hay for the horses. It was assumed that this treatment would not reduce the willingness of the Polish Konik horses with low nutritional requirements to consume the hay. Furthermore, it was believed that moistening would increase the palatability of this feed. The aim of this study was to determine time and frequency parameters and the amount of unconsumed dry, moist, or soaked hay. The research material comprised 12 Polish Konik horses consuming either 1 kg of dry hay, 2.1 kg of moist hay, or 3.3 kg of soaked hay on three sub...
A Revised View on Equine Hypertriglyceridemia, Hyperlipidemia, and Hyperlipemia. Hypertriglyceridemia, also known as hyperlipidemia or hyperlipemia, affects equids of all breeds and ages, mostly secondary to a negative energy balance triggered by a disease process. Increased triglyceride concentrations (TG) have been described in well-eating equids with endocrinopathies, atypical myopathy, severe liver disease, and after treatment with sodium-glucose transporter 2 inhibitors. The fact that equids can have substantially increased TG without showing clinical signs prompted reevaluation of the clinical effects of hypertriglyceridemia. As long as the consequences of high TG ar...
