The association of Clostridium perfringens with foal diarrhoea
… statistical association of these bacteria with foal diarrhoea. Each of five methods which favoured the recovery of <i>C. perjringens</i> in different physiological states were chosen to improve the sensitivity of isolation in a survey of foal diarrhoea for <i>C. perjringens</i> and other …

The effect of loading upon hoof wall growth and hoof shape in the Thoroughbred foal
… of the foot and is anisotropic and homogeneous. Foals appear to be born with symmetrical paired feet which by maturity are frequently unequal in angle and width. They stand within minutes of birth subjecting the hoof wall to loading. Hoof growth rate and hoof compression may be factors affecting …

Genetic Parameters of Foal Inspection Scores in the International Sporthorse Registry and Oldenburg Registry North America
Foal scores from the International Sporthorse Registry and Oldenburg Registry North America were used for statistical and genetic analysis. Scored traits include type and conformation (TC), athletic ability of movement (AM), overall development as related to age (OD), and total score (TS) …

Equine Luteinizing Hormone Profile Characteristics: Effects of Sampling Interval, Method of Analysis, Reproductive State, Gonadotropin-Releasing Hormone and Foal Removal
Studies in several species have indicated that luteinizing hormone (LH) profile characteristics vary with reproductive state. LH profiles may change rapidly, with pulses often occurring on an hourly or even more frequent basis. Only recently have these transitory changes been examined in mares. The …

Investigation of the Effects of Social Experience on Snapping Intensity in Equus caballus Foals
… to examine three aspects of Equus caballus foal snapping behavior. First, it suggested that the previous theoretical explanation for snapping established by behavioral researchers was incorrect. Second, as a means of suggesting an alternative hypothesis, this study proposed that snapping …

Influence of energy level during gestation on the postpartum endocrine system in the mare
… 90 d of gestation. The length of gestation and foal birth weight were unaffected by treatment. During 30 d postpartum, 120% DE-fed mares lost .16 kg/d while 100% DE-fed mares gained .33 kg/d (P<.04). Postpartum mare ADG were supported by foal ADG, with foals on 120% DE-fed mares having gained …

Evaluation of the pharmacokinetics, pharmacodynamics, and safety of enrofloxacin administration to pregnant mares
… 14 days at 280 days gestation, and allowed to foal. Foal cartilage and tendon strength were then evaluated at 30 days of age, and no effects of treatment were observed on gross or histologic examination. In contrast, foals treated with enrofloxacin at 14 days postnatally developed clinical …

Validation of a new method of determining cardiac output in neonatal foals
… finding in hospitalized, critically ill neonatal foals. Hypotension may be a function of low cardiac output or increased cardiac output and decreased systemic vascular resistance. In the first instance, treatment would include fluids and/or inotropes and in the second, fluids and/or vasopressors. …

Pre-weaning diet and stall weaning method influences on stress response in foals
The response of foals to the stress of weaning was examined in terms of a behavioral protocol and the responses of plasma ascorbate, serun1 cortisol, and the serum cortisol response to an ACTH challenge. Behavior scores (1 to 10) as an index of stress were assigned to each foal daily, with high …

Carbohydrate and Fat Supplementation in Grazing Mares and Foals
… traditional sweet feed. Thoroughbred mares and foals grazing bluegrass/clover pastures were used in these studies, twenty mares and their foals in 1994 to 1995, and twenty mares and foals in 1995 to 1996. Seasonal variation in pasture was examined, and the need for supplementation of nutrients …

Growth and the Somatotropic Axis in Young Thoroughbreds
… Characteristics of growth in 113 Thoroughbred foals born over a five year period were described with a series of empirical and physiological equations. Glycemic and insulinemic responses to different feed compositions were evaluated with glycemic response tests. The 24 hr pattern of plasma …

Interpretation of the Detection of Antibodies to Sarcocystis neurona in the serum and CSF of young horses
… to S. neurona from seropositive mares to their foals was evaluated. Foals were sampled at birth (presuckle), at 24 hours of age (postsuckle), and at monthly intervals. All foals sampled before suckling were seronegative. Thirty-three foals from 33 seropositive mares became seropositive with …

Vitamin E Status of Thoroughbred Horses and the Antioxidant Status of Endurance Horses
… to study vitamin E in Thoroughbred mares and foals. Middleburg is located in the Blue Ridge Mountains on Northern Virginia close to the site of one of the toughest endurance races in the world. This allowed me the opportunity to study vitamin E and antioxidant status in the horse during …

Equine Herpesvirus Type 1: Filling Gaps Toward Improved Outbreak Management
… associated with late-term abortion, neonatal foal death and neurologic disease. Once a horse is infected, the virus concentrates to local lymphoid tissue, where it becomes latent. The virus can recrudesce during times of stress, which can lead to the initiation of devastating outbreaks. Some …

The Role of Microbial Diversity in Female Reproductive Health: An Analysis of the Microbiome's Influence on Pregnancy Outcomes in Postparturient Mares
… in Lexington, KY, within 24-36 hours of foaling and before uterine lavage/infusion. Expected due date and date of delivery was noted for birth categorization, pre-term versus full-term. A foal is considered pre-term if born prior to 320 days gestation. Microbiota samples were prepared on …

Changes in Conformation and Walk Kinematics of Suckling and Weanling Warmblood Foals
… in conformation and walk kinematics of warmblood foals. The first study quantified linear and angular conformation changes of 13 warmblood foals during the first 9 mo of growth. An objective photographic method of evaluating conformation was used to obtain all data. All linear measurements …

Analysis of the maturation of Rhodococcus equi-containing vacuoles in macrophages
… which can cause severe bronchopneumonia in foals. In recent years, the role of this bacterium as human pathogen has been noted, as R.equi infections in humans have increase in frequency. This increase is associated with the rise in immunosupressed individuals, specially AIDS patients, where …

Glucose and insulin dynamics in late gestation mares and neonatal foals
… fat and fiber (FF) feeds, as well as neonatal foals born from pregnant mares fed SS and FF feed. Insulin modified frequently sampled intravenous glucose tolerance tests (FSIGT) were applied to pregnant Thoroughbred mares (n = 22) at 28 ± 3 wks (Period 1) and 47 wks (Period 2) gestation, as well …
