Abstract

The effect of replacing a commercial feed with hydroponic oat (HO) was studied on feeding trial to investigate its effects on performance, visceral organs and blood biochemistry of growing local rabbits. Four mixed diets based on a pelleted commercial rabbit feed (17% crude protein) were made by substituting HO ( 3% crude protein and 15.89% crude fiber) for the commercial feed (0, 20, 40 and 60%). Sixty four rabbits, 32 d of age and with an average body weight of 505 ± 15 g were assigned to the 4 treatments and caged in groups of 4 rabbits (2 females and 2 males/ cage). HO was grown for 8 d, and fed immediately after harvesting, including roots, seed and leaves. The rabbits were then slaughtered and the dressing proportions were calculated. Dry matter feed intake and growth rate decreased linearly by 1.16±0.080 g/d (P<0.001) and 0.998±0.062 g/d (P<0.001) per unit of HO increase. Rabbits consumed daily all the HO offered 0, 6.4, 12.8, and 19.1 g DM for 0, 20, 40 and 60% substitution levels, respectively. Both crude protein and digestible energy intake decreased linearly (P<0.001). Feed conversion and carcass yield percentage were not affected by treatments. Blood metabolites were within the medirabbit standards; however, level of HO had variable effects on visceral organs. It was therefore concluded that replacing pelleted commercial feed by wet HO had negative effects on rabbits’ performance.
