| Abstract | ||||
| This work was designed to process sugar beet by-products treated and untreated on form of silage and trying to overcome harmful oxalic acid as anti nutritional factor to improving of sugar beet top by ensiling either untreated or treated sugar beet top by supplemented with calcium carbonate as chemical treated (CSBS) or calcium carbonate+ pro biotic as biochemical treated (Biochemical) .Four digestion trials were carried out using three rams in each .The animals were nearly equal in body weight 62.4±0.7 kg, and fed the experimental diets according to NRC(1990). group 1 fed 50% pellets+50% clover hay (CH) as a control , group 2 , 3 and 4 were fed 50% pellets+50% one of different types of silages .The effect of replacing clover hay by different types of treated or untreated sugar beet tops silage on DM intake, Digestion coefficient, nutritive values, nitrogen balance were studded. Also hematological parameters of white blood cells (WBC′s) packed cells volume (PCV %) were also determined . The results indicated that both of chemical and biochemical treated silage were excellent have a firm texture, good smell, free from sign of mold, dust smells caramelized and tobacco or vinegar . All silages had a normal of pH (3.98- 4.11 ) with the superiority of those biochemical treated silage 4.58. The over all mean of TVFAs ranged between (5.44- 7.29) ml mol / 100ml, being higher for treated silages. Bio-chemical treated silage recorded the least concentration of NH3-N (16.67gm/100gm) .The fast rate of pH decline with untreated silage, whereas the Biochemical treated silage was remained unspoiled and markedly improved aerobic stability of silage. Data showed that nitrogen balance are the best within B-CSBS than all tested treatments. The ensiling of sugar beet tops with additives depressed the presence of anti–nutrition factors. also results clearly that rams fed on treated ensiled were increased significantly ( p< 0.05) the digestibility of OM ,CP,CF,NDF and ADL and improved significantly (p<0.05) TDN and DCP values. Ensilage of sugar beet tops with Biochemical had high advantages , improved the aerobic stability of silage and participate in feeding animals and minimize such problems of disposal pollution | ||||
