Through this paper, we proposed to establish the breeding performances of Mangalita races, red variety exploited in different conditions, namely intensive system and traditional system. For each growth system was created a batch of 20 individuals, male castrated and female, fully respecting the protocol of growth from each farm. Individuals from both batches were followed from weaning and up to the weight of 100 kg. Data on body weight, indicating more rapid achievement of 100 kg by weight Mangalita pigs reared in intensive system than those grown in traditional system about 2 months. Values recorded for average daily gains in the two batches shows a superiority for pigs reared in intensive system (258 g) than in traditional system (295 g) of about 37g (13%). Consumer index recorded throughout the experimental period was 5.20 kg for pigs reared in intensive systems and 6.4 kg for pigs reared in the traditional system. The results indicate that, between the two breeding systems, best results were obtained in intensive systems, which proves that to Mangalita race may apply intensive system leading to shorter growing period, respectively an index of lower consumption. To characterize more exactly the two systems will be achieved growth and meat quality analysis to see any differences.
