Abstract


The present paper has proposed to analyze two reproductive systems in swine breeding: natural service and artificial insemination and to estimate their economic efficiency, having as main objective their comparison. There were calculated technical indicators: total number of parturitions, fecundity index, natural service (artificial insemination)\sow/year, pigs born alive/sow/year, pigs born alive/parturition, weaned pigs/parturition, weaned pigs/sow/year, mortality index/sow/year, mortality index/parturition, and the main economic indicators: cost/sow, cost/pregnancy, cost/weaned pig, cost/natural service (artificial insemination) in the two reproductive systems. The two categories of primary data were statistically remade and there were concluded the results. Following analyze, the results were positive and also negative for the different indicators in both systems. After all, we consider that the best solution from the economic point of view and also for the animal breeding is to use the artificial insemination, but within a special laboratory, at its maximum capacity for recovering its payment.
