A total of 472 mixed parity sows were used from d 106 of gestation until weaning to determine the effects of Lys and energy intake in the last 7 d before farrowing on colostrum production, composition, and immunoglobulin G concentrations. On d 106 of gestation, sows were weighed, blocked by parity and weight, and allotted to dietary treatments. Treatments were based on corn-soybean meal diets fed to provide 1) 12.5 g SID Lys and 6.5 Mcal/d ME from d 107 to 112 of gestation, then 28 g SID Lys and 9.4 Mcal/d ME from until farrowing; 2) 12.5 g SID Lys and 6.5 Mcal/d ME from d 107 to 112 of gestation, then 40 g SID Lys and 13.3 Mcal/d ME from until farrowing; 3) 40 g SID Lys and 13.3 Mcal/d ME from d 107 of gestation until farrowing. After the birth of the first piglet, a 50 mL colostrum sample was collected. Colostrum samples were analyzed for fat, protein, total solids, lactose, and IgG concentrations. Individual piglets were weighed at birth and 24 h to determine colostrum intake and yield. Data was analyzed for treatment within parity and treatment main effects. There was a treatment within parity difference observed where sows on treatment 3 had decreased (P < 0.05) fat and total solids concentrations compared to treatment 1 sows, with no evidence for the difference within gilts. IgG concentrations tended to increase (P = 0.081) in females fed treatment 2 compared to treatment 1, regardless of parity. Total protein and lactose concentrations, as well as colostrum intake and yield, were similar across treatments, regardless of parity.
