a,b different superscripts indicate significant differences among treatments (p ≤ 0.05). 1 All values of body weight and backfat thickness were corrected for body weight and backfat thickness of the sow at the start of the experiment. T1: LoZEN from d109 gestation until d26 of lactation. T2: LoZEN from d109 gestation until farrowing and HiZEN from farrowing until d26 of lactation. T3: HiZEN from d109 gestation until d26 of lactation.
