Topic:Horse Management
Horse management encompasses the practices and techniques used to care for and maintain horses in various settings, including stables, pastures, and performance environments. This area of study covers a range of activities such as feeding, grooming, housing, exercise, and health monitoring to ensure the well-being and optimal performance of horses. Effective horse management requires an understanding of equine behavior, nutrition, and physiology, as well as the ability to implement routine care practices and respond to health issues. This page gathers peer-reviewed research studies and scholarly articles that explore the methods, strategies, and outcomes associated with different horse management practices.
Effect of diet on the oral glucose tolerance test in the horse. The effect of altering the diet during the week preceding the administration of an oral glucose tolerance test was studied in 7 horses. The results indicated that substantially lower oral glucose tolerance test curves are observed in horses fed a stable diet comprised of oat hay, a commercially prepared complete feed, and oat and alfalfa chaff, when compared with the curves for horses grazing clover and kikuyu pasture. It was concluded that, in utilizing the oral glucose tolerance test to assess small intestinal function in the horse, it may be necessary to consider the dietary history.
Urinary production in the healthy horse and in horses deprived of feed and water. Total daily 24-hour urinary output was obtained from 11 healthy horses fed alfalfa hay with free access to salt during periods of high environmental temperatures. Daily urinary volume averaged 15.6 L, with mean specific gravity of 1.028, osmolality of 1,040 mOsm/kg, and urinary flow rate of 1.24 ml/kg/hr. Total 24-hour sample collections of urine were also obtained from horses held without access to feed or water for periods of 24, 48, and 72 hours during high environmental temperatures. Average urine production under these conditions was 6.3 L during the 1st day; 3.2 L, the 2nd day; and 3.0 L...
Characteristics and fertility of stallion semen. A study of stallion fertility was conducted on commercial studs in eastern Australia over 4 breeding seasons (1974/75-1977/78). Data from 47 stallions (66 stallion seasons) aged 2-26 years and representing 7 breeds and 1664 mares were used to relate seminal characteristics to fertility. Percentage pregnancies per service was the most sensitive measure of fertility with stallions on commercial studs. Breed and age of stallion, breeding season and the referral status of the stallion ('suspect' or 'normal') had significant (P less than 0.01) effects on fertility. The semen characteristics that we...
The repeatability of seminal characteristics of stallions. Fifteen seminal characteristics were measured in ejaculates from 4 laboratory stallions and from 164 commercial stud stallions. Complete field and laboratory data were available from 536 and 531 ejaculates, respectively. These were obtained over 4 breeding seasons (1974/75-1977/78) and 9 breeds were represented. Stallions at commercial studs produced 1-13 ejaculates at intervals of approximately 4 weeks and ranging from 1 h to 1 year apart. Intra-class correlations or 'repeatability' of each seminal characteristic were calculated. Significant between-stallion variation occurred in all characte...
Control of nutritional secondary hyperparathyroidism in grazing horses with calcium plus phosphorus supplementation. A supplement system for the control of equine nutritional secondary hyperparathyroidism (NSH) was evaluated on 4 farms in the Arcadia Valley of the Queensland brigalow region. Thirty-three local stock horses (of which 13 had clinical NSH and 7 were recent introductions) were grazed on buffel grass (Cenchrus ciliaris) for the 6 months from September 1979 to February 1980. Each horse was fed 1.0 kg of a mixture of ground limestone plus dicalcium phosphate (1:2) in 1.5 kg molasses each week. The pasture was hazardous during this time (total oxalate content above 0.5% and calcium: oxalate ratio be...
Lysine supplementation of diets for yearling horses. Forty-six Thoroughbred and Quarter Horse yearlings were used in two experiments designed to determine the amount of lysine in the concentrate necessary to promote maximum growth when fed the Coastal bermudagrass (Cynodon dactylon) hay provided at 1% body weight (BW)/day. In the first experiment, a 196-day trial, supplemental protein sources and analyses of the concentrates compared were: (1) soybean meal (SBM; 15.4% crude protein, .70% lysine); (2) SBM + .2% lysine (15.7% crude protein, .81% lysine), and (3) brewers dried grains + .2% lysine (15.9% crude protein, .59% lysine). Concentrate inta...
Gas/liquid chromatographic analysis of pemoline in biological fluids using electron capture detection. An analytical gas/liquid chromatographic (GLC) protocol is described for the quantitation of pemoline in biological fluids of the horse. Plasma samples containing known quantities of pemoline and its analog as an internal standard (IS) were deproteinized with 5-sulfosalicylic acid, heated at 80 degree C, and centrifuged. 5-Phenyl-2,4-oxazolidinedione, the hydrolytic product of pemoline in acid medium, was extracted with dichloromethane (DCM). The organic layer was in turn re-extracted with 1% NaHCO3. The aqueous layer was acidified with HCI, and re-extracted with DCM, which was evaporated to d...
Effects of early experience on the learning ability of yearling horses. Twenty-four yearling Quarter Horse fillies were divided into three groups (I) very limited handling, (II) intermediate handling and (III) extensive handling. At about 14 months of age, each horse was preconditioned for 2 weeks and then run in a simple place-learning T-maze test in which it had to locate its feed. Thirty trials were run daily for 20 days, with the location of the feed changed each day. To retire from the maze, a horse had to meet the criterion: 11 correct responses in 12 tries, with the last eight being consecutive. Horses in Group II required the fewest trials to reach criteri...
Prevalence of Strongylus vulgaris and Parascaris equorum in Kentucky thoroughbreds at necropsy. At necropsy of 49 Thoroughbreds from farms with generally good parasite control programs in central Kentucky, examination was specifically made for presence of Strongylus vulgaris in all of the horses and of Parascaris equorum in 21 of them. None of the deaths of the horses was caused by infections of internal parasites. Visceral arteries were examined for specimens of S vulgaris and lesions related to migrating stages of this parasite. Contents of the small intestines were examined for P equorum. Specimens of S vulgaris were recovered from 19 (39%) horses, and arterial lesions were observed i...
Ventilation and environment in relation to equine respiratory disease. The physiological requirements of the horse appear to be reasonably well established and should be adequately provided by ventilation based on straightforward principles, relying largely on natural air flow. On the other hand, there are few objective values for ventilation required to promote good health or alleviate equine respiratory disease. In the absence of such knowledge it is only possible to rely on a logical application of sound principles and experience. Both indicate the satisfactory nature of ventilation by stack effect, aspiration and perflation. Buildings should be well insulated...
