Abstract: Records on various reproductive traits belonging to a total of 541 crossbred pigs out of which 308 were half-bred inter se (½ Hampshire × ½ Local) pigs and 233 were graded inter se (¾ Hampshire × ¼ Local) pigs from the year 2002 to 2013 constituted the material for study. Pigs were born, maintained and bred at ICAR- Mega Seed Project (MSP) and All India Coordinated Research Project (AICRP) on pigs, Assam Agricultural University, Khanapara, Guwahati- 781022, Assam, India. Phenotypic and genetic correlation coefficients among the reproductive traits were estimated from the data by paternal half sib method (Becker 1975) [1]. The phenotypic correlation coefficient in both the genetic group was found to be positive for all reproductive traits and highly significant in among some traits. The genetic correlation coefficient among reproductive traits are positive and ranged from low to high and in desired direction in most of the case for both the genetic groups.
