Abstract
Research on growth capacity, meat quality and genetic identification, kinship was directly monitored on 40 Ban Da Bac pigs raised from weaning period to 8 months of age. The data was processed, analyzed on statistical software and methods of analyzing the Cytochrome b gene sequence on modern devices, the results showed that: Absolutely growth ability was 124.14 - 132.75 gr / head / day, the average bodyweight at 8 months of age reached 28.22 - 30.55 kg / head. The percentage of hook jaws, the percentage of sawn meat and lean meat ratio were 70.90%; 63,00%; 40.10% respectively. The chemical composition such as dry matter, protein, lipid, and minerals contents were: 25.60%; 21.50%; 2.25%; 1.16%, respectively which tended to be higher than that of some other local pig breeds. Results of genetic sequencing analysis showed that the samples gave accurate results, the corresponding vertices on the graph for each nucleotide were obvious. Ban Da Bac pigs had a relatively high genetic diversity of haplotypes (Hd) of 0.602, and the level of nucleotide diversity (Pi) was 0.00148. Thus, Ban pigs grew slowly, the percentage of lean meat was average, good meat quality. They had close genetic relationship and originated from Asian wild boar.
