The main objective of this paper is to present the results of theresearch of the Swallow belly Mangalitsa genotype in the last six decades.According to the research, females reach the full maturity the age of 9-10 months,but they are mated at the age of 1-1.5 years. Average age at first farrowing is 556days. Reproductive ability is poorly expressed, with a strong maternal instinct.Fertility of the Mangalitsa is relatively poor because it gives birth to 1-12 piglets,on average 4 to 5 piglets, with an average body weight of 1.25 kg with a variationof 0.8 to 1.8 kg. The suckling period is about 50 days (from 47 to 53 days). Atlactation duration of 60 days, the piglet weight at the weaning ranges from 6-13 kg(average 9.61 kg) for piglets born in the spring, and from 7-15 kg (average 9.50 kg)for piglets born in fall. Depending on the rearing system, the start of fattening andfinal body weight, gains range 268 g to 830 g. The fat thickness (averagemeasurements) at the ridge was 10.2 cm, the middle of the back 7.9 cm and therump 8.1 cm, in previous studies, while in recent studies these values of fatthickness are somewhat lower, with the pre-slaughter body weight also being lower(the ridge 6.18 cm, the middle of the back 4.38 cm and at the rump 5.19 cm). Therecent research of the Longissimus dorsi muscle shows an intramuscular fat contentof 13.5%, protein content of 21.1% with specific qualitative properties pH45=6.11;pH24=5.50; CIE L*=40.13; a*=11.77; b*=3.73). In the musculus longissimuslumborum and thoracis, Mangalitsa (Swallow-bellied) pigs show higher levels ofmonounsaturated fatty acids (MUFA 55.1%) and lower levels of saturated fattyacids (SFA 35.3%) in comparison with Swedish Landrace pigs.
