^a–g

Denotes Ismean differences for the diet by d of gestation interaction (P ≤ 0.05), within each variable.

Beginning at d 30 of gestation, 82 pregnant ewes were randomly assigned to a control-fed (100%), restricted-fed (60%) or over-fed (140%) diet based on NRC TDN requirements during gestation. Four ewes did not complete the experiment due to reasons unrelated to the experiment. Ewes were euthanized at d 45, 90, or 135 of gestation, or allowed to undergo parturition (n = 5 to 7 ewes per diet per d of gestation).

Number of live ewes that BW and BCS were recorded at each d of gestation. Ewes were weighed immediately before euthanasia or within 7 d before parturition.

LSMeans are reported.

⁴

Ewe BCS was individually recorded by 2 observers using a scale of 1 to 5 (Russel, 1984).
