Table 5 Effects of feeding by-product feed-based silage on drinking, urination, and defecation in growing Hanwoo heifers

Item	Diet ¹⁾ with			SE	p-value
Item	RS	RSBFS	BFS ²⁾	SE	p-value
Drinking frequency/d	10.3	7.0	6.8	1.7	0.1153
Urinating frequency/d	4.5	4.3	5.3	1.2	0.6829
Defecating frequency/d	5.5^ab	3.5^b	6.8^a	1.1	0.0309

¹⁾The three diets were as follows: RS (free access to rice straw); RSBFS (free access to rice straw and BF-based silage); and BFS (free access to BF-based silage).
²⁾BF-based silage (BFS) was a by-product feed-based silage, which was composed of 50% spent mushroom substrate, 21% recycled poultry bedding, 15% ryegrass straw, 10.8% rice bran, 2% molasses, 0.6% bentonite, and 0.6% microbial culture, and was ensiled for over 2 weeks.
^a,b,cMeans with different superscripts within the same row are significantly different (p < 0.05).
