Goal: Consider hemoglobin focus (HbC) in sows and their offspring over consecutive parities.
Strategies: Twenty-three females had been monitored for HbC throughout parities 1, 2, and three at 7 timepoints (30 [± 2], 60 [± 2], 90 [± 2], and 112 days of gestation, 2 and 16 [± 1] days of lactation, and 5 [± 1] days put up weaning). Piglet HbC was measured inside 18 hours after delivery and at 16 (± 1) days of age. Pigs had been labeled as anemic (HbC < 10 g/dL) or nonanemic (HbC ≥ 10 g/dL) at every timepoint.
Outcomes: On gestation day 90, 71.1% of sows had been anemic throughout parities. In parity 1, HbC was much less on lactation day 16 than all gestational timepoints. In parity 2, HbC on lactation days 2 and 16 was lower than all gestational timepoints. In parity 3, HbC on lactation days 2 and 16 was lower than gestation days 30 and 60. Piglet anemia prevalence at 1 day of age was 55.8%, 36.3%, and 46.1% for parity 1, 2, and three, respectively. Piglet anemia prevalence at 16 days of age was 35.6%, 18.7%, and 15.9% for parity 1, 2, and three, respectively.
Conclusion: Lowering sow HbC over the reproductive cycle and lack of post-weaning restoration in parity 3 signifies iron declines with advancing parity and should influence long-term well being. Piglet anemia prevalence declined with advancing parity, suggesting a have to reevaluate piglet iron supplementation in litters from youthful females.
