| Abstract | ||||
| The purpose of this study was to assess the effect of vitamin C (Vit.C) and betaine (BET.) supplementation in diets of growing rabbits on growth performance, nutrient digestibility, rectal temperature, and blood serum constituents. The experiment lasted a 6-month period under Aswan condition. Thirty New Zealand White growing rabbits were used at age 3 months, with an average weight of 1193.88±55.94 gm, and they were divided into three treatments (10 rabbits in each treatment). The first group was basal diet (control), the second group was basal diet plus (1000 mg vit. C/kg diet), and the third was basal diet plus (1000mg betaine/kg diet). The second group rabbits fed 1000 mg vit.C/kg achieved the numeric increase in nutrients digestibility for DM (75.78%), OM (80.68%) and NFE (68.38%) compared control (73.04%,79.60% and 68.36%) respectively. While in the third group rabbits fed 1000 mg betaine/kg diet achieved the numeric increase in nutrients digestibility for CP (75.97) and EE (57.55) compared control (74.34 and55.81) respectively. The Third group fed 1000 mg betaine/kg diet achieved the highest significant (P<0.05) final body weights (3353 g) compared with the control (3060 g). Also, rectal temperature was decreased (39.2 °C) compared with the control (39.39°C) while vitamin C supplementation recorded (39.22°C). Rabbits fed 1000mg betaine/kg diets recorded non-significant increase in serum total protein, albumin, urea, creatinine triglyceride, ALT and glucose concentration while serum globulin was significantly increased due to dietary betaine supplementation. supplemental dietary betaine enhanced growth performance and reduced rectal temperature in growing rabbits. | ||||
