Feeding selenium-biofortified alfalfa hay during the preconditioning period improves growth, carcass weight, and nasal microbial diversity of beef calves
Fig 5
Nasal microbiota profiles of healthy calves after weaning (week 0), at the end of the Se-supplementation preconditioning period (week 9), and in the feedlot (week 12).
During the 9 week preconditioning period, calves consumed alfalfa hay harvested from a field not fertilized with Se (Control) or harvested from a field fertilized with sodium-selenate (High Se; application rate of 90 g Se/ha; n = 15 calves per group for Control and High Se).
