Geriatric horses are older equines that typically exhibit age-related physiological changes impacting their health and management. As horses age, they may experience alterations in metabolism, immune function, and musculoskeletal integrity. These changes can increase their susceptibility to diseases and necessitate specialized care. Research on geriatric horses often focuses on understanding the aging process, identifying common health issues such as osteoarthritis and dental problems, and developing management strategies to enhance their quality of life. This page gathers peer-reviewed research studies and scholarly articles that explore the physiological changes, health challenges, and management practices associated with aging in horses.
Tretow M, Hain AM, Bienert-Zeit A.The dental syndrome EOTRH is a painful, progressive dental disease with an unknown aetiology. The often painful nature of EOTRH emphasises the need for a better knowledge of the underlying pathogenic mechanism and risk factors. A comparative analysis of haematological, biochemical and endocrine values in EOTRH-affected and non-affected horses has not been described. Objective: To compare haematological, biochemical, and endocrine parameters in EOTRH-affected and non-affected horses to detect risk factors for horses developing EOTRH. Methods: Cross sectional. Methods: Blood samples of 154 Icela...
Vachkova E, Arnhold S, Petrova V, Heimann M, Koynarski T, Simeonova G, Piperkov P.The impact of donor age on Adipose-derived mesenchymal stem cell (ASC) functionality and safety remains insufficiently characterized, particularly in equine models. This study investigates the influence of age on ASCs proliferation dynamics and the expression of tumorigenic and apoptosis-related markers. Equine ASCs were isolated from juvenile (<5 years), middle-aged (5-15 years), and geriatric (>15 years) horses and assayed across multiple passages. The relative mRNA expressions of pluripotency (Oct4), tumorigenic (CA9), and apoptosis-related (Bax and Bcl 2) markers were evaluated. The Gomper...
Gozalo-Marcilla M, Redondo JI, Bettschart-Wolfensberger R, Domenech L, Doménech J, Johnston GM, Taylor PM.To report on the Confidential Enquiry into Perioperative Equine Fatalities 4 (CEPEF4). Methods: Confidential, observational, prospective, multicentre, cohort study. Methods: 47,396 horses/ponies undergoing general anaesthesia (GA). Methods: Characteristics of each GA (249 variables) were collected. Outcomes after seven days were ALIVE (or discharged), EUTHANASIA or DEAD. Logistic regression analysed patient demographics and the anaesthetic drugs (p < 0.05). Results: Data were collected from 47,396 GAs in 93 centres in 28 countries. Death rates were 1.2% overall, 0.6% for cases classified as NO...
Wonghanchao T, Sanigavatee K, Petchdee S, Chettaratanont K, Thongyen T, Wanichayanon B, Poochipakorn C, Chanda M.The physiological capabilities of horses begin to decline after they reach 15 years of age. However, some exceptionally talented horses can continue their sports careers beyond this age, raising concerns about their welfare. This study investigated animal welfare by observing resting heart rate (HR) and heart rate variability (HRV) metrics in geriatric horses participating in similar training or physical activities compared to younger adult horses over 30 min periods. Forty-six horses of varying ages and activity levels were divided into four groups, including horses under 15 years practising ...
Pinn-Woodcock TL, Llanos-Soto SG, Ivanek R, Goodrich E, Frye E, Wells A, Mullen K, Arbittier E, Hughes L, Berryhill E, Brosnahan P, Buslinger L....To determine whether seasonal variation in equine plasma ACTH concentrations is affected by latitude between 29.7°N and 45.0°N in the US. Unassigned: A cohort study was performed between June 2019 and May 2020 in which plasma ACTH was measured monthly by chemiluminescence immunoassay. The study involved 201 apparently healthy horses from 9 locations within the US classified into northern, central, and southern latitude cohorts. Data analysis was performed with 3 major objectives: (1) identify outlier ACTH concentrations and horses; (2) estimate ACTH upper reference limits to define expected ...
