This study explores the supplementation of Moringa oleifera leaves on carcass characteristics and meat quality of rabbits. The results show that the addition of Moringa oleifera leaves does not adversely affect the carcass characteristics and meat quality of rabbits, thus it can be recommended as a nutraceutical source for sustainable rabbit production.
Moringa oleifera leaves (MOL) containing phytochemicals could be used to replace synthetic growth promoters to improve products quality in sustainable rabbit production. This study explores the supplementation of MOLM on carcass characteristics and meat quality of rabbits. A total of 64, 28 days-old male weaned New Zealand white rabbits (600 +/- 8.58 g live weight) were randomly allocated to four diets in completely randomised design. The rabbits were reared on iso-energetics and isoproteic diets formulated by incorporating MOLM at 0, 5, 10, and 15% and were humanely slaughtered after 6 weeks. Heart weight increased linearly with MOLM levels (R (2) = 0.50; p = 0.007) whereas slaughter (SLW), hot carcass (HCW), cold carcass (CCW), legs, head and kidneys weights were increased quadratically. Also, liver decreased quadratically (R (2) = 0.41; p = 0.03) with MOLM levels. Fillet lightness (L*) (R (2) = 0.21; p = 0.02), redness (a*) (R (2) = 0.14; p = 0.04) and yellowness (b*) (R (2) = 0.14; p= <0.0001) decrease whereas peak force increased (R (2) = 0.63; p = 0.02) quadratically with MOLM levels. Leg muscle a* (R (2) = 0.45; p = 0.0001) and cooking loss (R (2) = 0.19; p = 0.0009) decreased linearly with MOLM levels. Only aroma (R (2) = 0.04; p = 0.04), juiciness (R (2) = 0.05; p = 0.04) and connective tissues (R (2) = 0.03; p = 0.05) increased linearly with MOLM levels. In conclusion, MOLM did not adversely affect rabbit carcass characteristics and meat quality hence it can be recommended as a nutraceutical sources for sustainably rabbit production.
