CS and fetal growth restriction: Citrate synthase activities were not different between semitendinosus muscles from control (343 ± 13 μmol min−1 (mg protein)−1) and IUGR lambs (348 ± 12 μmol min−1 (mg protein)−1) but were lower (P < 0.05) in IUGR‐AR lambs (287 ± 15 μmol min−1 (mg protein)−1) compared to control or IUGR lambs.
