Selectionofthebestsilagestrainsfortheproduct „GRAS“ status Antibiotic resistance Risk analysis Virulence activity strainidentity • Isolation and characterization • of bacteria out of silages • Evaluation and selection of most effective strains • Productionoflacticacid (high amount / very fast) • Productionofaceticacid • Ratio lactic/aceticacid (differentiation homo- and heterofermentative) • Goodgrowth in a broad pH range • Goodefficacy in a broadrangeofforagesandgrains • Safety • Risk assessment • Stability • Fermentation performance • Highest product quality

  6. 1. Evaluation and strain selection • Range of metabolic end products • Production of lactic acid (high amount / very fast) • Production of acetic acid • Ratio lactic/acetic acid • (differentiation homo- and heterofermentative) • Good growth in a broad pH range • Good efficacy in a broad range of forages and grains

  7. Biomin®BioStabil Selected strains: • for different substrates • for different energy sources • more stable Multistrain Lactobacilus plantarum Enterococcus faecium Lactobacillus brevis Criteria for selection

  11. DM LOSSES moisture% fillingseepage gas Top-spoilFeedout Total Based on Forages: The Science of Grassland Agriculture, 4th ed. See Bickert et al (1997

  12. Silage Average Dairy Farm: 500 cows + young stock. Corn silage : 8300 t ( 2900 t DM) @ R500/ton Hay : 700 t ( 570 t DM) @ R700/ton Total costs/value: (8300 ton*R500/t)+(700 ton*R700/t)=4,6 mln R

  13. Dry matter losses Losses are; Best case: 17 % 4,6 mln R *17% = 782.000 R or Worst case: 30%4,6mln R* 30% = 1,38 mln R

  14. Energy losses

  15. BioStabil effect on Energy and DM Values that can be expected provided good management practises: 1 Mcal = 4,184 MJ Energy (NEL, Mcal)/kg milk: 0,72511

  16. Energy losses Corn silage 2900 t DM= 18.4 mMj recovery Max Losses 30% = 5520000 MJ Min Losses 5 % = 920000 MJ OR 540 T extra dry corn!

  17. economics Cornsilage 2900 t DM: Energyrecovery: 0,18 Mj/kg dm 1500000 kg*0,18 Mj= 270.000 Mj. Corn= 8,5 Mj = 61 t Corn=150.000 R Withouttakingtheproteinquality in consideration
