Table 3.

Effects of feeding an avian-derived polyclonal antibody preparation against Streptococcus bovis (PAP-Sb) or Fusobacterium necrophorum (PAP-Fn) for 19 d on ruminal S. bovis counts, in steers fed a high-grain diet (Exp. 2)

	PAP-Fn × PAP-Sb interaction
Item	Control	Only PAP-Fn	Only PAP-Sb	PAP-Fn + PAP-Sb	SEM
No. of steers	4	4	4	4
S. bovis,¹ millions/mL	24.0^b	5.5^a	6.2^a	12.4^ab	1.4

	Main effect
	No PAP-Fn	PAP-Fn
F. necrophorum,² thousands/mL
No. of steers	8	8
Day 0	14.4^b	18.3^b	2.8
Day 19	13.5^b	0.4^a	2.8

^a,b

For S. bovis counts, within rows, and for F. necrophorum counts, within rows and columns, means without common superscripts differ (P < 0.05).

PAP-Fn × PAP-Sb interaction (P = 0.02).

Day × PAP-Fn (main effect) interaction (P = 0.01).
