Tóm tắt: | An experiment was carried out at the experimental farm and laboratory of Can Tho University to evaluate feed utilization, nutrient digestibility and growth rate of crossbred rabbits. It was a factorial design in which the first factor was length of sugarcane stalk residue (SSR) (3 and 10 cm in length) fed ad-libitum, and the second factor was different supplement of operculina turpethum (OT) (0, 100, 200 and 300 g/rabbit/day) with three replications and four rabbits per experimental unit. Results show that SSR intake was slightly higher (P>0.05) for rabbits fed 3 cm in length and gradually decreased with increasing supplement of OT in the diets (P<0.05), while OT intakes were remarkably increased (P<0.05). Total dry matter, crude protein, ether extract and metabolizable energy intakes were higher for rabbits given SSR at 3 cm long (P<0.05) and when increasing the levels of OT supplement (P<0.05). Digestibility coefficients of DM and CP were higher for animals offered 3 cm long SSR (P<0.05), and NDF values were clearly improved with increasing OT supplement in the diets (P<0.05). The higher nitrogen intake and retention were found for rabbits fed 3 cm SSR (P<0.05) and supplemented with 300 g OT/rabbit/day. Daily gain and final live weight were significantly higher for rabbits fed 3 cm length SSR and supplemented with 300 g OT per animal per day (P<0.05). It was concluded that rabbits fed 3 cm long SSR and supplemented with 300 g OT per animal per day in the diet had better growth rate and gave higher economic returns. |
