[en] This study was carried out at the animal farm of Hanoi University of Agriculture, Vietnam to evaluate the growth performance and meat quality of stress negative Piétrain pigs. The study concerns the body weight (BW) of 116 pigs at 7.5 months of age and the ultrasound measurements on 83 live animals in order to determine backfat thickness, longissimus muscle depth and lean meat percentage (LM). Meat color (C.I.E L*, a* and b*), peak shear force (SF), pH at 24h (pH24) and at 45 minutes (pH45) post mortem were measured on 31 meat samples. Meat chemical composition (dry matter, protein, lipids and ash) was determined on 23 meat samples. All the data were analyzed according to a linear fixed model including gender effect (female and intact males) and Halothane genotype (CC and CT). The interaction between gender and genotype was not observed and therefore it was ignored from the final model. The results show that BW and LM were not significantly different between genotypes (P>0.21) while females were heavier than males (101.11 vs. 93.85 kg, P=0.0011). LM of female and male were respectively 63.27 and 63.56%. Gender and genotype didn’t affect meat quality and chemical composition (P>0.05) except pH24 (P=0.0011), a* (P<0.0001) and lipids (P=0.0012) for gender effect. The pH45 (6.50 and 6.45 for females and males) and pH24 (5.34 and 5.49 for females and males) were in the range corresponding to a normal meat. The obtained results show that stress negative Piétrain pigs have high lean meat percentage and satisfactory meat quality under tropical climatic conditions in Vietnam.
