Study On The Combine Effect Of Admixture Micro-organism Treatment Of Maize Straw And Caragana

In this experiment, Maize straw and Caragana were mixed with different proportion to study their feeding values for sheep raising. Feeding values, in terms of nutrient contents, animal intakes and rumen degradation of the mixed feed of Maize straw and Caragana were evaluated after microbial dosage and enzyme dosage treatments. Besides, the combine effect of the mixed feed were analyzed to discuss whether they can improve the feeding value of single feed(Maize straw or Caragana) or not, and if exist the combine effect between the mixed feed. The result are as follows.①The treatments of micro-organism treatment reduced the fiber substances content of mixed feed significantly(P﹤0.05).②The effect of bacteria and enzyme dosage treatments to the mixed feed of Maize straw and Caragana surpassed the effect of bacteria and enzyme dosage treatments to single Caragana, and the organoleptic investigation of 30% Caragana group both adding 0.1%, 0.3% bacteria dosage and adding 0.05%,0.1%,0.15% enzyme dosage as well as 50% Caragana group adding 0.05% enzyme dosage all reached the standard of fine quality micro-organism treatment forage.③DMI of sheep to the mixed forages with bacteria and enzyme dosage treatments significant higher than to the mixed forage with non- micro-organism treatment (P﹤0.05), and the palatability of mixed forage of Maize straw and Caragana with enzyme dosage treatments better than the one of bacteria dosage treatments.④DM,OM,CP,NDF,ADF,ADL degradation of Maize straw and Caragana admixture forage with bacteria dosage treatments higher than non- micro-organism treatment Caragana, but lower than non- micro-organism treatment Maize straw. There were a significant difference between the OM degradation of 70% Caragana group adding 0.15% enzyme dosage, DM and OM degradation of 30% Caragana group adding 0.05% enzyme dosage, DM, OM and ADF degradation of 30% Caragana group adding 0.15% enzyme dosage and DM,OM,ADF degradation of Maize straw and Caragana(P﹤0.05).⑤The DM, NDF degradation of 30% Caragana group supplemented 0.05% enzyme dosage displayed positive combine effect. Therefore, Maize straw and Caragana can be mixed to feed domestic animal in practical production, but should to consider the proper combine ration and optimization supplementation of enzyme dosage.⑥Using the bacteria dosage to treat the forage of maize straw and Caragana did not...
