Linseed meal during early pregnancy increases litter size in pigs
To determine how feeding linseed meal (LSM) during gestation influences litter size, placental weight, and piglet growth, sows (n = 30) received a phytoestrogen-free Control diet throughout gestation; 12.5% LSM diet throughout gestation (LSM114); or 12.5% LSM diet from day 1 to day 15 of gestation and control diet until parturition (LSM15).
