Influence of roughage and grain processing in high-concentrate diets on the performance of long-fed Holstein steers.
The effects of roughage source and timing of inclusion in high-concentrate diets on feedlot performance were evaluated in each of 2 yr with 144 and 120 long-fed Holstein steers, respectively. Roughage, when included in the diet, was delivered in a built-in-roughage (BIR) pellet supplying 15 and 6% roughage (percentage of DM) or hay crop silage (HCS) supplying 7 and 10% roughage (percentage of D...
متن کاملEffect of Different Ratios of Concentrate and Roughage on Lipid Synthesis by Rumen Microorganisms In Vitro
The effect of different feeding ratios of concentrate to roughage on ruminal lipid synthesis in vitro was examined. Three sheep fitted with a rumen fistula were fed three different ratios (8:2, 4:6 and 0:10) of concentrate and roughage, and their rumen liquor were used for incubation. C-labeled glucose or sodium acetate as substrate was added to cultures of rumen liquor, and they were incubated...
متن کاملNet utilization of roughage and concentrate diets by sheep.
1. Two diets, an all-roughage diet and a high-concentrate diet, were fed at two levels, a low level of estimated 1-5 times maintenance energy requirement and a higher level of estimated two times maintenance energy requirement, to South African Mutton Merino castrated male sheep, aged 13 months and in fairly lean condition at the start of the 93 d experimental period. 2. Body composition and en...
متن کاملEnergy efficiency of growing ram lambs fed concentrate-based diets with different roughage sources.
Poor-quality roughages are widely used as fiber sources in concentrate-based diets for ruminants. Because roughage quality is associated with the efficiency of energy use in forage-based diets, the objective of this study was to determine whether differing the roughage source in concentrate-based diets could change the energy requirements of growing lambs. Eighty-four 1/2 Dorper × 1/2 Santa Inê...
