Plasma Ascorbic Acid Concentration Following Ascorbic Acid Loading in Chicks

Abstract

Three trials were conducted to determine the changes in plasma ascorbic acid (AA) associated with varying levels and duration of supplemental AA. In Trial 1, supplemental AA was provided in the drinking water at 0, 5, 25, 50, 100, 250, 500, 1000, and 2000 micrograms/ml (ppm). Plasma AA concentrations were significantly elevated in chicks receiving 250 ppm AA or greater. In Trial 2, plasma AA concentrations increased significantly within 4 hr of supplementation in chicks receiving 1000 ppm AA. Statistically, maximum AA values occurred some 8 hr following the initiation of supplementation. Removal of the supplemented water resulted in rapid declines in plasma AA in Trial 3. Plasma AA values significantly higher than controls were maintained 16 hr after the removal of the supplemental water. Values returned to those of controls within 20 hr.

Effect of Ascorbic Acid Supplementation Methods on Some Productive and Physiological Performances of Laying Hens

“…Pardue et al (1984) confirmed that with increased AA intake using water, the absorption and utilization of AA by chicken could be reduced due to excessive renal excretion of AA.…”

Effects of Supplemental Ascorbic Acid on the Performance of Broiler Chickens Exposed to Multiple Concurrent Stressors

“…Levels of supplemental AA used in this experiment were sufficient to elevate plasma AA. This assumption is based on the findings of Pardue et al (1984), who demonstrated that 250 ppm AA significantly elevated plasma AA concentrations in 4-wk-old Hubbard x Hubbard broilers, whereas supplementation of 100 ppm or less did not.…”

Effects of Antioxidants Vitamin E and C on ErythrocyteFragility, HaemoglobinIndex and Colonic Temperature of Transported Japanese Quails (Coturnixcoturnix japonica)

“…Furthermore, the fact that these vitamins are known to inhibit the release of cortisol [40,42], the chief fear hormone, may be involved in the mechanism of regulation of the body responses, aimed at maintaining homeostasis. In addition, VE and AA have been reported to reduce heat load in birds [12,14,16,21,43]. Thus, the administration of the antioxidants pre-transportation reduced the adverse effects of incremental THI or heat load experienced by the birds inside the vehicle during the transportation period.…”
