Study in 'Type'
Measures Of Bone Mineral Content In Mature Dairy Cows
The objectives of this investigation were to assess the relationship between chemical measures and imaging estimates (radiographic photometry and dual-energy x-ray absorptiometry) of bone mineral content in dairy cows and to evaluate the effects of parity, stage of lactation, and site of measurement (fused third and fourth metacarpal bone vs. caudal vertebrae 14 and 15) on bone mineral content.
Vitamin A Repletion In Thoroughbred Mares With Retinyl Palmitate Or Beta-carotene
Forty-five Thoroughbred mares used in an 8-mo depletion study were kept for an additional 20 mo on the same three forage diets (15 mares each): 2-yr-old orchardgrass hay and vitamin A-free concentrate on a drylot (HC); pasture, orchardgrass/alfalfa hay, and vitamin A-free concentrate (PHC); or pasture and orchardgrass/alfalfa hay only (PH).

Preweaning Diet And Stall Weaning Method Influences On Stress Response In Foals
The stress response of foals during weaning was examined in terms of a behavioral protocol and the responses of plasma ascorbate, serum cortisol, and the serum cortisol response to an ACTH challenge.
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.
Preweaning Diet And Stall Weaning Method Influences On Stress Response In Foals
The stress response of foals during weaning was examined in terms of a behavioral protocol and the responses of plasma ascorbate, serum cortisol, and the serum cortisol response to an ACTH challenge.
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 […]
