A systematic study was conducted to analyze the production and reproduction performance of Large White Yorkshire pigs under organized modern breeding farm condition in Thanjavur districts of Tamil Nadu state, India. Data on 74 farrowings for the periods from 2017 to 2020 were collected from Modern Pig Breeding Unit, Livestock Farm Complex, Veterinary College and Research Institute, Orathanadu. TANUVAS, Tamil Nadu. Measures of reproductive and production performance assessed in this study were mean litter size at birth, mean litter size at weaning, mean birth weight, mean weaning weight, number of piglets produced per sow per year, age at first farrowing, mean gestation period and farrowing interval. The estimated over all mean of litter size at birth, mean litter size at weaning, mean birth weight, mean weaning weight, number of piglets produced per sow per year, age at first farrowing (days), mean gestation period (days) and farrowing interval (days) were 7.89±0.51, 7.63±0.50, 1.38±0.03, 10.30±0.80, 9.76±2.29, 399.5±6.01, 113.26±0.52 and 206.80±5.90, respectively.
