Digestible energy requirements for growth in Hereford and Charolais × Hereford steers

Abstract

1979, 1984,1985, 1986 Hironaka unpublished) were used to examine the effect of various feeding programs and forms of feed on the rate and efficiency of gain and carcass characteristics. A total of 717 steers were fed individually from about 6 mo of age until slaughter (

Influence of barley silage:concentrate ratio on rate and efficiency of liveweight gain, diet digestibility and carcass characteristics of beef steers

“…I :24.9, 58.3:41.7, 34.4:65.6, 1 8.9:8 l. 1, 8.0:92.0, 3.1:96.3 or 0:100 on a DM basis (100:0, 90:10, 80:20, 60:40, 40:60, 20:80, 10:90 or 0:100 as-fed basis). The quantity of feed offered was restricted for the first 24 wk to an amount calculated to obtain 0.6 kg d -r of gain (Kozub and Hironaka 1992) We observed a decline in DE intake as concentrate was increased above about 65%.In the study by Parrot et al (1968), the steam-rolled milo may have been rolled very thin, which could have reduced the intake of 90 and 100% milo diets . The cubic response of liveweight gain:DE intake (Table 3) (Hironaka et al 1979 Sutton (1980).…”
