Abstract
The purpose of this work was to estabilish the reproduction performances realized by the Mangalita sows at first parturition exploited in elite unit of pigs growth from Romania, named S.C. SUINPROD S.A. ROMAN. The researches were made on 25 Mangalita sows, blond variety, being observed the main reproductive parameters. After the researches made, the following results were obtained: age at first parturition (between 228 and 318 days, average 266 days), weight at first seeding (between 97 and 114 kilograms, average 102,12 kg), number of piglets born (between 5 and 10, average 7,6 piglets), number of piglets weaned (between 4 and 10, average 6,64 piglets), weight at birth (between 850 and 1200 grams, average 1030 grams) and the weight at weaning (between 4,5 kg and 7,32 kg, average 5,84kg). The data obtained were compared with the results from the literature of speciality. We can conclude the fact that, at all the reproductive parameters the obtained results indicate the lower performances in comparison with the pure races and with the hybrids of large productivity, in exchange the prices obtained from the valorification of the carcasses from the race Mangalita show that if this race is exploited it is very profitable.
