| Abstract |
This work consists of two experiments; the first one was designed to
determine the chemical composition and nutritive values of clover hay (CH) and peanut vines hay (PNVH) or peanut vines silage (PNVS) using twelve mature New Zealand White (NZW) male rabbits with an average body weight of 2.5 kg and 8 months old. The second one was carried out to study the performance of growing NZW rabbits fed diets containing PNVH or PNVS, which replaced different levels (0, 50, 75 and 100%) of CH in the mixed ration. Growth performance, feed conversion, some carcass traits, and, economic efficiency of experimental rations were determined. The results indicated that both of PNVH and PNVS had higher EE, NFE and ash content and lower CF content compared with Cf. Feed intake was significantly higher (P<0.05) for rabbits fed rations containing PNVH than those fed rations containing PNVS. Moreover, PNVH had the highest digestibility coefficients values for OM, CP and NFE compared with the values of CH and PNVS, while CF digestibility was the highest for PNVS. No significant differences were found among both CH and PNVS for OM, CP and NFE or CH and PNVH for CF and NFE. The digestibility values of EE were nearly similar. Rabbits fed rations containing PNVH achieved significantly (P < 0.05) the highest body weight and, average daily gain compared with the other rations, Moreover, rabbits fed rations containing 75 or 100% PNVH showed the best feed conversion comparing with rabbits fed PNVS. Inclusion of PNV as hay or silage in rabbit rations reduced feed cost. The rabbits fed rations containing 50% of PNV hay or silage recorded the best (P<0.05) values for dressing percentage. Based on the nutritional and economical results of the present study, it was clear that PNV as hay or silage were highly palatable roughages. Moreover, PNV have a beneficial effect on improving productive performance of growing rabbits and decreased, feed cost due to the lower price of the tested ingredients and this reflected on the economical efficiency values.
Keywords: peanut vines, digestibility; growth performance, carca.'Is characteristics.
