Calcium chloride supplementation in sows: Enhancing farrowing efficiency and piglet viability during transition period.

High-prolific sows have a high incidence of stillbirth and asphyxiated piglets due to calcium deficiencies. Calcium is important for enhancing farrowing efficacy and colostrum production. Calcium chloride (CaCl), an acidogenic compound that lowers dietary cation-anion difference (DCAD), promotes calcium mobilization, thereby mitigating the risk of calcium deficiency.
