Abstract
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 (p<0,005).

Rezumat
Dintre īnsusirile productive ale porcinelor prolificitatea ocupa un loc deosebit de important deoarece de numarul purceilor fatati depinde īn primul rānd numarul de purcei īntarcati si implicit a celor destinati īngrasarii si livrarii pentru carne, precum si eficienta economica. Cercetarile au presupus luarea īn studiu a 200 de scroafe apartinānd hibridului PIC, respectiv 100 scroafe PIC 1050 si 100 de scroafe Camborough la care au fost apreciati principalii indicatori reproductivi īn functie de numarul fatarii. La fecunditate se constata o crestere a rezultatelor pe masura īnaintarii īn vārsta a scroafelor, respectiv pāna la fatarea a treia (82,2% PIC 1050 si 83% Camborough) dupa care acestea īncep sa scada. Prolificitatea, la ambele loturi de scroafe analizate, a fost influentata de numarul fatarii. Cele mai bune rezultate, īn privinta numarului de purcei fatati, au fost īnregistrate la fatarea a treia (11,42 cap. PIC 1050 si 12,26 cap. Camborough) iar cele mai mici la prima si a cincia fatare. Īntre prolificitatea maxima si cea minima fiind īnregistrate diferente semnificative (p<0,005).
