PRODUCTIVE PERFORMANCES OF TWO ITALIAN CROSSBRED PIGS FED HIGH ENERGY DIET
The aim of the trial was to compare the average daily gain (ADG), the carcass characteristics, and the meat and fat quality of 18 Italian crossbred pigs fed high energy diets formulated for improved genotypes (digestible energy: DE >14 MJ/kg DM).

| Summary: | The aim of the trial was to compare the average daily gain (ADG), the carcass
characteristics, and the meat and fat quality of 18 Italian crossbred pigs fed high
energy diets formulated for improved genotypes (digestible energy: DE >14 MJ/kg
DM). Nine “Fumati” crossbreds (Large White x Mora Romagnola; average initial
live weight: 84 kg) and nine “Borghigiana” (Large White x Nera di Parma;
average initial live weight: 90 kg), reared under similar environmental and
nutritional conditions, were slaughtered at the average final weight of 180 kg (285
days). Calculated dry matter intake (DMI) and feed conversion index (FCI) were
similar; no significant differences were observed with respect to average daily gain
(ADG: 679 vs. 658 g/d). At slaughtering, the dressing percentage of the Fumati was
significantly lower than that of the Borghigiana (80.9 vs. 84.5). The Fumati seemed
more prone to fattening than the Borghigiana, as confirmed by the statistically
higher percentage of belly (14.9 vs.12.2), and fat (3.9 vs. 2.4) and marbling of M.
longissimus dorsi (2.7 vs. 1.4). On colour analysis, the Fumati had statistically
higher L* and hue values, and lower a* of M. longissimus dorsi. The fatty acid
composition of meat was similar between crossbreds; backfat fatty acid composition
of the Fumati showed a significantly higher percentage of saturated fatty acids
(SFA), and lower amounts of monounsaturated and polyunsaturated fatty acids
(MUFA and PUFA) than in the Borghigiana. Results showed that performances and
meat quality of local crossbreeds still bred in semi-intensive systems, like Fumati
and Borghigiana, can be positively influenced when fed diets considered suitable
for improved pig genotypes. |
