Table 1 Basic statistics on the investigated traits individual maximum and minimum of number total born piglets (Max_TBP and Min_TBP), and individual range of number total born piglets (Range_TBP), number of total born piglets and number of piglets born alive in first parity (TBP_first and NBA_first) in German Landrace sows (RA01) and Large White sows including crossing sows (RACOM) with at least five individual parities each

From: Maximum number of total born piglets in a parity and individual ranges in litter size expressed as specific characteristics of sows
