The objectives of this study were to observe farm productivity measurements and to examine the interrelationships between growth performance measurements and the relationships between reproductive performance and growth performance of pigs on 91 farrow-to-finish swine farms in Japan. Partial correlations analysis was performed using female inventory changes (%) for reproductive performance and market weights for growth performance as controlled variables. In reproductive performance, means of preweaning mortality risks and adjusted 21-day pig weights were 11.3±0.4% and 6.2±0.1kg, respectively. In growth performance, means of days to market, daily gain, and mortality of fattening pigs were 168.7±1.5 days, 0.65±0.01kg, and 5.0±0.3%, respectively. Higher daily gain was correlated with lower mortality of fattening pigs and shorter days to market (P<0.05). Lower preweaning mortality risk and higher adjusted 21-day pig weight in reproductive performance were correlated with higher daily gain and lower mortality of fattening pigs in growth performance (P<0.05). Greater number of pigs weaned per mated female per year was also correlated with higher daily gain and shorter days to market (P<0.05). Mortality of female pigs in breeding herds was not correlated with that of fattening pigs. These results show that higher reproductive performance is related with higher growth performance of pigs on farrow-to-finish swine farms. The adjusted 21-day pig weights and the preweaning mortality risk in breeding herds may be key measurements to link reproductive performance to growth performance.
