• Resumen

  • The effect of crossbreed on meat chemical composition of Celta pig breed slaughtered at 12 months was studied. A total of 32 pigs Celta crossbreed (8 for each genotype group) with Duroc, Landrace, Pietrain and Mangalica were used. Animals were reared in an outdoor system and slaughtered at 12 months. After 24 h post-mortem, longissimus dorsi muscle was excised and pH and chemical composition (moisture, intramuscular fat, protein, ash and Fe-hemo) were assessed. The pH values did not show significant (P>0.05) differences among groups. Regarding moisture content, statistical analysis displayed significant (P<0.05) differences among crossbreed, since the higher values were observed in samples from crossbred with Landrace breed (73.67%) and the lower values were found in samples from crossbred with Mangalica breed (72.69%). On the other hand, intramuscular fat also showed significant (P<0.01) differences among crossbreed, since the lower values were observed in samples from crossbreed with Pietrain (1.45%) compared to the other ones (2.50, 2.84 and 2.41% for samples from crossbreed with Duroc, Landrace and Mangalica, respectively). Finally, Fe-hemo content was significantly (P<0.01) affected by the crossbreed, since the higher values were obtained from crossbreed with Mangalica breed (0.62 mg/100 g).
