First-litter commercial cross-bred gilts were treated with levamisole (1.5, 2.5, or 3.5 mg/kg of body weight) weekly during the last 4 weeks of gestation, because similar treatment of dairy heifers had improved postpartum maternal health and neonatal survival. In the gilts, differences in reproductive performance were not found on the basis of pig survival at birth, pig survival at weaning, birth weight, or weaning weight. Also, differences between treated and control gilts were not found in response of circulating lymphocytes to mitogen stimulation (phytohemagglutinin A, concanavalin A, and pokeweed mitogen). In all gilts, the lymphocyte response to mitogen stimulation was decreased during the first week after farrowing.
初产商品杂交后备母猪在妊娠最后4周每周用左旋咪唑（1.5、2.5或3.5毫克/千克体重）进行处理，因为对奶牛小母牛进行类似处理可改善产后母体健康和新生儿存活率。在这些后备母猪中，根据出生时仔猪存活率、断奶时仔猪存活率、出生体重或断奶体重，未发现繁殖性能存在差异。此外，在经处理的后备母猪和对照后备母猪之间，循环淋巴细胞对有丝分裂原刺激（植物血凝素A、刀豆球蛋白A和商陆有丝分裂原）的反应也未发现差异。在所有后备母猪中，产仔后第一周淋巴细胞对有丝分裂原刺激的反应均降低。
