dc.description.abstract Three hundred arid fifty three lactating sows were used to determine the effects of increased dietary lysine on sow and litter performance. At farrowing, sows were assigned to com-soybean meal lactation diets consisting of either 1.0 or 1.3% total lysine. A treatment by parity interaction was observed, with first parity sows fed 1.3% lysine having heavier litter weaning weights than sows fed 1.00/0 lysine. Surprisingly, third and fourth parity sows fed 1.3% lysine had lower litter weaning weights than those fed 1.0% lysine. No other treatment by parity interactions existed. No differences were observed in the number of pigs weaned or pig survivability. Sows fed 1.3 % lysine tended to consume less feed in the first week of lactation than sow fed 1.0% lysine (9.6 vs 10.0 Ibid), with no differences observed during week 2 or overall. No differences were observed in subsequent performance of the sows on days to estrus; farrowing rate; or number of pigs born, born alive, stillborn, or born mummified. This experiment showed that increasing dietary lysine from 1.0% to 1.3% increased litter weaning weights for parity 1 sows but not for older sows. en_US
