Analysis of variance table presenting the results of a study examining the effect of vaccination against Fusobacterium necrophorum infection, on average daily gain (adjusted for 4% shrink) in feedlot cattle, while also adjusting for diet during the feeding period. The 2 diets used in this trial were a limit-fed grain-based diet and an ad libitum forage-based diet.
