"Horses" is a broad topic that encompasses various aspects of equine biology, behavior, and management. This category includes studies on the anatomy, physiology, and genetics of horses, as well as their behavior, nutrition, and care. Research in this area may also cover the historical and cultural significance of horses, their roles in agriculture, sport, and therapy, and the challenges associated with their conservation and welfare. The page aggregates peer-reviewed research articles and scholarly studies that explore the multifaceted relationships between humans and horses, examining both scientific and socio-economic perspectives.
The objective of this study was to compare effects of butorphanol (BUT) or buprenorphine (BUP), in combination with detomidine and diazepam, on the sedation quality, surgical conditions, and postoperative pain control after cheek tooth extraction in horses, randomly allocated to 2 treatment groups (BUT: = 20; BUP: = 20). A bolus of detomidine (15 μg/kg, IV) was followed by either BUP (7.5 μg/kg, IV) or BUT (0.05 mg/kg, IV). After 20 min, diazepam (0.01 mg/kg, IV) was administered and sedation was maintained with a detomidine IV infusion (20 μg/kg/h), with rate adjusted based on scores to ...
Two closed horse herds (Old Lot 4 and Field 24), infected since 1966 with Population B small strongyles resistant to thiabendazole (TBZ) and phenothiazine (PTZ), were terminated in February, March, and May, 2005. At necropsy, only the large endoparasites were identified and counted. The number of horses on pasture was 14 (239 days of age to 23 years old) for Old Lot 4 and two (3 to 20 years old) for Field 24. The time of the last antiparasitic treatment, relative to the year (2005) of necropsy, was 26 years for Old Lot 4 and 9 years for Field 24 horses. Gasterophilus intestinalis third instars...
Vandaele Z, Flyps J, Cuypers C, De Baere S, Devreese M, Schauvliege S.Subanaesthetic doses of ketamine (0.5 mg kg) provide analgesia in several species, but there is limited information on the pharmacokinetics and clinical effects of intramuscularly administered ketamine in horses. This study investigated the pharmacokinetics of ketamine and norketamine, and evaluated clinical effects, ataxia, and vital parameters, following intramuscular and intravenous administration of 0.5 mg kg ketamine in nine healthy horses, using a randomized two-period crossover design with a 1-week washout period. Plasma concentrations were analyzed using Ultra-High Performance ...
Sakai DM, Ishikawa Y, Im JSY, Zhang S, Reed RA, Quandt JE, Barletta M, Knych HK.Administering large volumes of bupivacaine in the rectus abdominis sheath (RAS) block in horses could cause local anesthetic toxicity. This study aimed to evaluate the pharmacokinetics of 2 mg/kg bupivacaine in RAS blocks and the associated toxicity risk. Six healthy adult horses were sedated with xylazine and received an ultrasound-guided bilateral 2-point RAS block. Plasma samples were collected at baseline and from 5 min to 24 h after the block and analyzed using liquid chromatography-tandem mass spectrometry. A noncompartmental analysis was performed to determine the maximum concentr...
Herschel TL, Pelli A, Winter K, Scharner D.Penetrating wounds of the hoof are common and potentially life-threatening injuries in equine veterinary practice. The aim of this study was the systematic data analysis of horses presenting to the clinic with a solar puncture wound.In this retrospective study, patient data from horses presented with a puncture wound to the hoof in the period from September 2008 to August 2024 were collected. The analyzed data covered signalment, intended use, and insurance status. The following were also considered: previous history including the period between injury and presentation to the clinic, affected ...
