| Abstract | ||
| The present study was carried out to estimate the effect of using sugar beet tops as untreated or treated silages which concerning oxalic acid as a natural toxic component, on growing lambs fed on untreated sugar beet tops silage (USBS) or treated as well as chemical sugar beet top treated silage (CSBS) or biochemical sugar beet tops silage (B-CSBS).Twenty four growing Rahmany lambs with an average body weight of 21.99 ± 0.4 kg and aged four months were used in this study . Lambs were divided into four similar groups (6 animals each) and assigned randomly to four experimental rations according to the requirement of NRC (I990) as follows , the first group fed diet received 50% concentrate feed mixture (CFM) as pellets +50% clover hay (CH) as a control , second group fed 50 % CFM (pellets) + 50 % untreated sugar beet top silage (USBS), third group fed 50 % CFM (pellets) +50 % chemical treated sugar beet top silage (CSBS) and forth group fed 50 % CFM (pellets)+50 % biochemical treated sugar beet top silage(B-CABA) .The experiment lasted for 26 weeks at El-Serw Animal Production Station, Animal Production Institute Agriculture Research Center. The data indicated that body weight gain (BWG) was improved with B-CSBS, CSBS and control groups the values were 26.48, 22.41, 25.34 and 27.83 (kg) for control, USBS,CSBS and B-CSBS, respective . thus , the TDN and DCP significantly better with B-CSBS , control and CSBS. the lowest values (p<0.05) of TDN ( 61.28) and DCP (8.16) were recorded with USBS group. Moreover feed conversion based on DM was better with B-CSBS followed by control, CSBS ,lastly USBS and the values were 8.61, 9.97,8.85 and 8.32 for control, USBS,CSBS and B-CSBS respectively .The same trend was observes with daily feed intake and water consumption . Oxalic acid values of experimental rations as well as USBS, CSBS and B-CSBS intake were 9.82, 3.95 and 3.87 mg /100respectively ,whereas total oxalic acid excretion values were 6.88, 2.59 and1.05 mg / 100g / ml for USBS,CSBS and B-CSBS respectively. .The minerals as well as calcium, phosphorus, magnesium, sodium, iron, manganese , Zink and potassium were significantly (p<0.05) higher in B-CSBS and CSBS groups compared to USBS and control one ,except for the potassium intake it was lower in B-CSBS than other test groups, Sugar beet tops silage chemical or biochemical treated be used safety, successfully and economically in ration of growing lambs at 50% of nutritional requirements economic efficiency was lower with untreated sugar beet top silage (114 LE) , whereas the economic efficiency was improved with the tow groups received B-CSBS and CSBS by 180 and 208 LE respectively . | ||
