Caribou (Rangifer tarandus) rely on the short Arctic growing season to restore body condition, support the demands of lactation, and prepare for the long arctic winter, making them susceptible to even small changes in forage availability or quality. Body condition in the summer and autumn is linked to winter survival rates and fecundity in cows, critical factors in the productivity of caribou populations. Climate change predictions of warmer and wetter northern winters suggest increased snowfall over Alaska’s North Slope, which has recently been verified between 1995 and 2017. However, a comprehensive analysis of how deeper snow will affect caribou forage …

Sixteen ruminally cannulated crossbred steers (529 ± 45 kg initial body weight, BW) wereused to evaluate in situ dry matter (DM), neutral detergent fiber (aNDF), and N degrada-tion characteristics of low-quality prairie hay, blood urea-N (BUN) and rumen fermentationparameters in steers provided a protein supplement with or without Micro-Aid®(MA; plantderived saponin). Steers were allowed ad libitum access to chopped prairie hay (49 g crudeprotein (CP)/kg DM and 738 g aNDF/kg DM) and randomly assigned to one of four treat-ments: (1) no supplement (C), (2) cottonseed meal and wheat middlings: 920 g DM/d (PC;positive control), (3) MA added to PC to …
