Utilization of rice milling by-products and dried sugar beet pulp in rabbit rations
Abstract: A total number of eighty four New Zealand White (NZW) rabbits 5 weeks of age and 545.35 ± 7.36 g average live body weight were allotted at random to seven similar experimental groups (of 12 rabbits each) and fed on seven different pelleted rations contained 0, 10, 20 and 30% (RM) or 10, 20 and 30% (SBP). The feeding trail extended for 8 weeks. The aim of the study to investigate the effect of introducing rice milling by-products (RM) and dried sugar beet pulp (SBP) in rabbit rations by different levels on growth performance, nutrients digestibility, mortality rate, some blood parameters, carcass characteristics and economic efficiency. Results obtained indicated that, digestion coefficients values of CP, CF, EE and NFE of diets containing 20% RM or SBP were significantly (P<0.05) higher than those fed control diet increasing RM and SBP levels from 10 to 20%, significantly (P<0.05) increased TDN from 63.09 & 61.87% to 64.87 & 65.16% and DCP from 12.02 & 11.98% to 12.33 & 12.37%, respectively. Introducing RM or SBP by 20% in rabbit diets grew 16.55 and 19.26% higher than control, respectively. The diets containing 10 and 20% (RM) and (SBP) showed better significantly (P<0.05) values of feed conversion than the other diets. Concentrations of serum aspartate aminotransferase (AST) and alanine aminotransferase (AL T) exhibited insignificant activities in rabbits fed diets containing different levels of MR or SBP. Serum total protein, albumin and globulin concentrations were significantly (P<0.05) higher in the blood of rabbits fed diets containing 10 and 20% RM or SBP than those fed the other diets. The significantly (P<0.05) increase of serum creatinine and urea-N levels in rabbits fed diets containing 20 and 30% RM or SBP within the normal range. Hot carcass weight and dressing percentages were significantly (P<0.05) higher in the 20% RM or SBP group than those of the control group. Chemical composition values of meat, with the exception of ether extract values were not significantly differed among the experimental groups. Economical efficiency values of rabbits fed diets contained 20% RM or SBP at marketing age (13 weeks) was higher than those of the other diets. It could be concluded that, rice milling by-products and dried sugar beet pulp could be introducing up to 20 of growing rabbit rations without any adverse effects on growth performance.
