Effect of Feeding Selenium-Fertilized Alfalfa Hay on Performance of Weaned Beef Calves
Figure 3
Relationship between amount of Se applied by fertilization (g Se/ha) and observed WB-Se content (ng/mL) in weaned beef calves consuming alfalfa hay grown in fields not fertilized with Se (0 g Se/ha), or harvested from fields fertilized with sodium-selenate at an application rate of 22.5, 45.0, or 89.9 g Se/ha for 7 wk (n = 15 calves per group).
The normal reference interval for whole-blood Se concentrations of beef cattle is 120 to 300 ng/mL.
