Experiments were conducted to examine the effects of low crude protein (CP) diet on reproductive performance and nitrogen excretion of sows during early and middle stages of pregnancy (from mating to 75 days pregnant). Thirty-six sows were divided in two experiments. In experiment 1, the reproductive performance from first to sixth parity were investigated using twenty sows. They were fed 2.5kg per day of diets containing standard CP (12.5%), middle CP (10%) or low CP (7%) during early and middle stages, 2.5kg per day of standard-CP diets during last stage, and ad libitum diets containing 15% CP during lactating stage. In experiment 2, the same diets as experiment 1 other than middle CP group were fed to the sixteen sows with the restricted feeding of 2.0kg per day, and they were investigated in the reproductive performance and the urinary nitrogen excretion at the first parity.<br>In experiment 1, sows fed 2.5kg per day of standard-, middle- and low-CP diets (lysine intakes were 13.8, 11.0 and 8.3g per day, respectively) showed similar new born and weanling litter size, body weight of piglets, and the interval of postpartum estrus from first to sixth parity.<br>In experiment 2, sows fed 2.0kg per day of low-CP dies (6.6g of lysine intake per day) showed the significant low newborn and weanling litter size (P<0.05), but the other reproductive performance parameters were similar to sows fed 2.0kg per day of standard diets (11.0g of lysine intake per day). Urinary nitrogen excretion for sows fed low-CP diets resulted in 64% of that from sows fed standard diets (P<0.01).<br>These results show that the reduced CP regimen above 8.3g of lysine per day for sows at the early and middle stages of pregnancy has no adverse effect on the reproductive performance from first to sixth parity, and suggests the probability of the reduction of urinary nitrogen excretion.
