Abstract
The aim of the study was to analyse the effect of sex, storage time and muscle type (m. longissimus dorsi and m. biceps femoris) on quality traits of the meat of French Lop rabbits. The muscles were obtained from 12 males and 12 females slaughtered at the age of 90 days. The characteristics analysed included pH, colour parameters, water holding capacity and proximate composition. No effect of sex or muscle type was found (P>0.05) on the pH of the meat in any of the periods analysed. The storage time differentiated (P≤0.01) between pH45min and pH24h and between pH45min and pH7days. None of the colour parameters was influenced by sex (P>0.05), but they were significantly affected by storage time (P≤0.01). Redness and yellowness were also influenced by the type of muscle (P≤0.01). The rabbit meat stored for 7 days was characterised by higher drip loss than the meat stored for 24 hours (1.31-1.49% vs. 3.34-3.57%, P≤0.05). The m. biceps femoris of both sexes had a greater capacity to hold water as measured by the pressure method than m. longissimus dorsi (P≤0.01). There was no effect of sex or muscle type (P>0.05) on the level of cooking loss. Sex and muscle type also had no influence (P>0.05) on the proximate composition of French Lop meat.
