Vitamin A Status Of Neonatal Foals Assessed By Serum Retinol Concentration And A Relative Dose Response Test
Greiwe-Crandell KM, SD Kronfeld, LS Gay, D Sklan, PA Harris. 1996. Vitamin A status of neonatal foals assessed by serum retinol concentration and a relative dose response test. Pferdeheilkunde 12(3):181-183. The objective of the study was to evaluate the vitamin A status of the newborn foal. Serum retinol and the relative dose response (RDR) test […]
Seasonal Vitamin A Depletion In Grazing Horses Is Assessed Better By The Relative Dose Response Test Than By Serum Retinol Concentration
Vitamin A influences growth and reproduction in horses. A retinol dose response (RDR) test for retinol has been shown to be better than serum retinol concentration for assessing vitamin A status in other species, so we have compared these two methods in the horse.
The Effect Of Chromium Supplementation On Metabolic Response To Exercise In Thoroughbred Horses
Chromium is essential nutrient in humans and at this time its only known role is that is a component of the glucose tolerant factor (GTF) which potentiates the action of insulin. This paper discusses the study performed to determine the affect of Chromium supplementation on metabolic response in exercised trained thoroughbreds.
Vitamin A And Beta-carotene Supplementation In Horses On Different Forage Systems
Greiwe-Crandell KM, SD Kronfeld, D Sklan. 1995. Vitamin A and beta-carotene supplementation in horses on different forage systems. Annales de Zootechnie 44 (Suppl):308. Forages, such as pastures and hays, often require supplementation to be utilized efficiently, especially as the nutritional value of pastures declines during fall and winter. A common supplement is vitamin A which […]
Vitamin A Depletion In Thoroughbreds: A Comparison Of Pasture And Non-pasture Feeding Regimes
Greiwe-Crandell KM, DS Kronfeld, GA Morrow, W Teigs. 1993. Vitamin A depletion in Thoroughbreds: a comparison of pasture and non-pasture feeding regimes. Proc. 13th Equine Nutr. and Physiol. Symp., Gainesville, FL.
Phosphorus And Selenium Depletion In Thoroughbred Mares And Weanlings
Observations on the mineral status of mares and foals have been made in the course of a study which was concerned primarily with the influence of beta-carotene and vitamin A on reproductive efficiency and growth.
Dietary Phosphorous Concentrations Related To Breaking Load And Chemical Properties Of Rib Bone In Heifers
Effects of dietary P on breaking load and chemical properties of bone were evaluated in growing beef heifers.
Criteria To Evaluate Bone Mineralization In Cattle: I. Effect Of Dietary Phosphorus On Chemical, Physical, And Mechanical Properties.
Fourteen Angus heifers (210 +/- 6 kg initial BW) were allotted randomly to either a low P (LP: .12% P, DM basis) or an adequate P (AP: .20% P, DM basis) diet fed for 14 to 16 mo under drylot conditions on concrete floors to determine the influence of dietary P on chemical, physical, and mechanical properties of bone.
Influence Of Dietary Phosphorus Level On Growth And Production Of Growing Beef Heifers
Williams, S. N., L. R. McDowell, A. C. Warnick, L. A. Lawrence and N. Wilkinson. 1989. Influence of dietary phosphorus level on growth and production of growing beef heifers. Florida Beef Cattle Research Report. Gainesville, FL. 1989:64. An experiment was conducted to study the effect of two levels of dietary phosphorus (either .12 or .20% […]
Influence Of Dietary Iron On Growth, Tissue Mineral Composition, Apparent Phosphorus Absorption And Chemical And Mechanical Properties Of Bone In Ponies
Lawrence, L. A., E. A. Ott, R. L. Asquith and G. J. Miller. 1987. Influence of dietary iron on growth, tissue mineral composition, apparent phosphorus absorption and chemical and mechanical properties of bone in ponies. Proc. Equine Nutr. Physiol. Soc. 10:563.
