Background: Growth is a critical stage influencing the future athletic performance and economic value of Thoroughbreds. In pastoral systems, extrinsic factors may exert a particularly strong influence on development.Objectives: To analyze the influence of stud farm, birth month, and birth year on body weight of Thoroughbred foals raised in pastoral systems.Methods: A 10-year longitudinal study (2009-2018) included 2408 Thoroughbred foals (51% females, 49% males) from seven stud farms of Pampas region. Body weight was recorded from 5 to 19 months of age. The Brody model was used to estimate ind...

The objective of the present study was to characterize the nutritional composition, fatty acid profile, and IgG concentration of the milk produced by Chilean Corralero horse (CCH) mares from breeding farms located in southern Chile. Forty-five milk samples were collected from three of the biggest breeding farms (coded as A, B and C) specialized in breeding and selection of CCH in Chile (15 mares sampled per farm). Farms differed in days in milk (DIM). A negative association between DIM and ash, milk protein, milk solids, saturated fatty acids (SFA), and gross energy (GE) was found, whereas DIM...

Liver disease in horses is primarily evaluated using the routine serum biochemical profile with a few additional specialty tests of liver function that are performed when indicated. Serum enzyme activities are evaluated to indicate hepatocellular damage and cholestasis. Liver function is evaluated using synthetic markers like BUN, albumin, bilirubin, and clotting times, while clearance function tests such as serum bile acids and ammonia are performed separately. Most equine liver disease is characterized by some degree of hepatocellular damage and cholestasis, while decreased liver function is...

Birgitsdotter LM, Friedrichsen Borg H, Kendall A.Medical induction of maternal behavior can be a safer and less stressful way to introduce orphan foals to nurse mares, compared with traditional methods that are time consuming and require restraint of the mare. Published data on results of medical treatment in a large number of mares are lacking. Objective: Describe a hormone-based protocol for foal grafting, including nonsteroidal anti-inflammatory drugs, dinoprost tromethamine, and oxytocin, and to report treatment outcome. Methods: A total of 113 nurse mares and 27 mares that had rejected their foals. Methods: Retrospective case series. Ca...

Reported complication rates after dental repulsion for equine exodontia are high (up to 80%), but repulsion methods have changed notably in the last 20 years. Objective: Describe the outcome for 20 cases after dental repulsion using small diameter repulsion pins. Methods: Retrospective case series. Methods: Records of horses that underwent cheek tooth repulsion were reviewed (2014-2023). Inclusion criteria included: mandibular or maxillary cheek tooth extraction where oral extraction failed and repulsion was used to complete extraction, and where clinical follow up information was available....

The objective of this study was to graft autologous mesenchymal stem cells (MSCs) at the site of surgical repair of a soft palate defect in an adult horse in an attempt to improve wound healing and to investigate whether the transplanted MSCs would integrate into the soft palate structure and participate in regeneration. Bone marrow was collected from an adult horse with a full-thickness soft palate defect. The MSCs were isolated, cultured in monolayers, and labeled with 5-bromo-2-desoxymidine (BrdU) and chloromethylbenzamido-DiI-derived (cm-DiI) before transplantation. The soft palate defect ...
