The effects of chemical treated corn silage (using urea and formaldehyde) on rumen ecosystem (pH, sedimentation and floatation, methylene blue reduction, total VFA, rumen ammonia) and blood metabolites (urea and glucose) in sheep were investigated. Sixteen sheep (41.85±4.6 kg) were used in a 4-treatment completely randomly design. The treatment contented: Corn Silage (CS), Corn Silage treated Urea(10 g kg-1)(CSU), Corn Silage treated Formaldehyde(4 g kg-1) (CSF), Corn silage treated urea (10 g kg-1) and formaldehyde (4 g kg-1) (CSFU). The ruminal pH had significant differences between treatments (p<0.05). The sedimentation andfloatation time, methylene blue reduction, total VFA showed no significant differences between treatments. The ruminal ammonia nitrogen in CUS was significantly more than the other treatments. The blood urea nitrogen in CSU and CSFU was more than the other treatments (p<0.05). There was no significant differences for blood glucose concentration among treatments. This study indicated that formaldehyde decreased ruminal ammonia nitrogen, resulting high escaped protein and offer users flexibility in formulating rations according to the productive performance of target animals. |

In order to determine of fermentation characteristics of treated and untreated barley grain the experiment was carried out. The treatment contain Untreated Barley Grain (UBG), Teated Barley Grain at 120°C, 5´ (TBG 1) and 20´ (TBG2) and 100 C, 5´ (TBG 3) and 100°C, 20´ (TBG 4). The gas production was measured at 2, 4, 8, 16, 24, 36 and 48 h. The gas production data were fitted by the equation of P =A(1-e-ct). The gas production of treated barley grain at 48 h was lower than the other treatments (p<0.05). Also the gas production of soluble and insoluble fractions (A) and rate of gas production in most of treated barley grain were lower than the other treatments (p<0.05). Treatment of barley grain by heat had low gas production resulting and improved efficiencies of barley grain and increased by pass protein. |
