“…2 (Table 7). Redden et al (2011) reported no difference in DMD between high-and low-RFI yearling ewes on a chopped hay maintenance diet. Residual feed intake was independent of BC in yearling ewes fed ad libitum or at a maintenance restricted feeding level (Redden et al, 2013).…”

“…After a 10-d acclimation period, feed efficiency was measured for 6 wk (Redden et al, 2011). All 58 lambs had ad libitum access to feed in individual bunks.…”

“…The authors reported a highly significant correlation of 0.62 between consecutive measures within individuals. On the contrary, a study in growing ewe lambs indicated no relationship between RFI during growth and RFI during maintenance as mature ewes (Redden et al, 2011), although diets differed substantially from a pelleted feed during the growth phase to a hay-based diet during the rnaintenance phase, which could have impacted results. We found that weekly RFI records during the first 90 DIM had a repeatability of 0.47 within lactation and 0.20 across lactations, suggesting that the trait is only moderately consistent within individual cows over time.…”

“…According to , among the physiological processes that regulate RFI variation among individuals, 37% of them can be attributed to metabolism and stress. For sheep, there are few studies on feed efficiency from an RFI perspective (Knott et al, 2010;Redden et al, 2011;Rincon-Delgado et al, 2011). Inferences about the subject are supported primarily by information from other species, especially cattle.…”
