The present study was conducted in Pig Breeding Unit, LRS, AAU, Mandira to assess the productive and reproductive performances of Ghungroo pigs. A total of 10 Ghungroo pigs (5 sows and 5 Gilt) were selected for the study. Information on productive and reproductive performances of these pigs was taken from the available records and under observations. Various performance traits of Ghungroo pigs like age at puberty, seual maturity, age at first farrowing, farrowing interval, gestation period, piglet weight, littersize and piglet mortality were studied. The mean age at puberty in Ghungroo pig was found to be 6.48±0.24 months while age at sexual maturity was found to be 9.39±0.32 months. The average age at the first farrowing, farrowing interval, gestation period, piglet weight at birth, litter size and piglet mortality were found to be 14.06±0.25 months, 6.93±0.24 months, 113.22±0.49 days, 0.97±0.01 kg, 8.22±0.46, and 16.21%, respectively. These study is useful in the selection of breeding stock for future parents and to produce healthy and quality piglets.
