The effect of organic mineral supplementation in the ration with total mixed fiber ammoniation as basal feed to rumen environment

This study aims to evaluate the effect of organic mineral supplementation on ration with total mixed fiber as basal feed to rumen environment. This study consists of four organic mineral level on ration and four replicates of each treatment. The treatments are : P1: 60% ammoniation TMF + 0 × Organic macrominerals (Ca. P. and S) NRC (2000) + 15% Swamp Legumes. P2: 60% ammonia TMF + 0.75 × Organic macrominerals (Ca. P. and S) NRC (2000) + 15% Swamp Legum. P3: 60% ammonia TMF + 1 × Organic macrominerals (Ca. P. and S) NRC (2000) + 15% Legum Swamp P4: 60% ammoniation TMF + 1.5 × Organic macrominerals (Ca. P. and S) NRC (2000) + 15% Swamp Legum. Each treatment is added with an organic micro-mineral consisting of 40 ppm organic Zn. 10 ppm organic Cu. 0.10 ppm organic Se. and 0.30 ppm Cr organic. Parameters measured are N-NH3 concentration. total VFA concentration. SCFA concentration. pH rumen. methane gas production and microbial population. The results show that organic mineral supplementation had a significantly different effect (P <0.05) on rumen condition characteristics (N_NH3. total VFA. SCFA and methane). and bacterial cellulolytic populations but did not affect the total bacterial rumen and protozoan population. It can be concluded that organic mineral supplementation of Ca. P and S 1.5 times of requirement according to NRC (2000) gives the best result for improving the rumen environment with Total mixed fiber ammoniation (TMFA) as basal feed and l5 supplementation % legume swamp (kemon air).
