Background
Nutritional strategies for sows designed to reduce stress around parturition are suggested to support postpartum recovery and longer-term productivity. Past studies using spray-dried plasma in sow feed reported productivity benefits in sow and litter performance. Other studies indicate stressed animals fed diets with spray-dried plasma have a more efficient immune response to the stress which supports animal recovery and health. The purpose of the present study was to determine if 0, 0.5 or 2.5% spray-dried porcine plasma (SDPP) in peripartum feed provided from entry in maternity through d 5 of lactation affects sow productivity and serological immune and oxidation status markers around parturition and if peripartum feed provided only during the initial parturition affected post-weaning sow productivity parameters including litter size of the next parturition.
Results
In the initial parturition, litter size for total born pigs was linearly reduced ( P < 0.05) as dietary SDPP increased and percentage of stillborn pigs per litter decreased quadratically ( P < 0.05) for sows fed 0.5% or 2.5% SDPP compared to 0% SDPP in peripartum feed. In the subsequent parturition, total born pigs from parity 1 and 2 sows linearly increased ( P < 0.05) and live born pigs tended ( P = 0.09) to linearly increase as level of SDPP increased. The change in total and live born litter size from the initial to the next parturition linearly ( P < 0.01) increased as dietary SDPP increased for parity 1 and 2 sows. Diet did not differ ( P > 0.10) for serum cytokine markers. Serum glutathione peroxidase activity linearly increased ( P < 0.01) with increased dietary SDPP for both prepartum and postpartum sampling periods.
Conclusions
Inclusion of SDPP in peripartum sow feed reduced percentage of stillborn pigs during the initial parturition and increased litter size of parity 1 and 2 sows in the next parturition. The reduced oxidation stress around parturition as indicated by increased serum glutathione peroxidase activity for sows fed SDPP in peripartum feed suggests mitigation of oxidation stress can reduce stillborn rate and have a long-term benefit on subsequent litter size for parity 1 and 2 sows.
