Between productive traits of pigs, prolificacy plays a particularly important because the number of piglets farrowed depends primarily on the number of piglets weaned and therefore those intended for fattening and meat supply and economic efficiency. The research study involved taking 200 sows belonging to the hybrid PIC, 100 sows PIC 1050 and 100 sows Camborough which were appreciated key reproductive indicators based on the number of calving. The fecundity of the results is an increase with age in sows, which runs until the third calving (82.2% and 83% Camborough PIC 1050) after which they begin to fall. Prolificacy, analyzed in both groups of sows was influenced by parturition number. The best results, the number of pigs farrowed were recorded at the third parturition (11.42 head PIC 1050 and 12.26 head. Camborough) and lowest in the first and fifth parturition. Between maximum and minimum prolificacy being recorded significant differences (p 0.005).recorded (p0,005).
