Abstract

The present study was designed to investigate the efficacy of different dietary levels of ethanolic guava leaf extract on growth performance, blood parameters, carcass traits, meat chemical composition and economic feed efficiency of growing rabbits. Eighty APRI line rabbits (5 weeks of age and average live body weight of 522±7.12 g) were divided and assigned randomly into four experimental groups of 20 rabbits in each (10 males +10 females). Rabbits in the 1st group were fed complete diet (basal diet) without any supplements (G1, control), while those in the 2nd (G2), 3rd (G3) and 4th (G4) groups were fed the same diet supplemented with guava leaf extract at levels of 1, 2 and 3 ml/kg diet, respectively. Results showed rabbits at the end of growing period (Final weight) were significantly (P<0.05) heavier in treatment groups than in control one. In this line, rabbits fed 1.0, 2.0 and 3.0 and 3.0 ml guava leaves extract/ kg diet (G3 and G4) had the highest final body weight were heavier by about 3.1, 7.7 and 8.5% than those in G1 (control diet). Daily feed intake was not significantly affect by supplementing guava leaves extract in diets.Feed conversion ratio was significantly improved with increasing guava leaves extract level in diets. Mortality rate was 10, 10, 0 and 0 in G1, G2, G3 and G4, respectively. Carcass percentage was significantly (P<0.05) higher in G3 and G4 than in G1 and G2. Rabbits in G3 and G4 showed the highest revenue (146.7 and 148.6%) relative to those in G1 (100%). In conclusion, guava leaves extract could be successfully incorporated into the diet of growing rabbits up to 3.0 ml/ kg diet, which improved production performance without adverse effects on health status during growing period, under Egyptian environmental conditions.
