  2. II. Trials weaned piglets HendrixUTD BV Ashorst BV (=farm Van Asten; 1800 sows + 12.000 gr-f) WEDA Holland BV

  3. Fermentmix LAB: 107 to 109 cfu/ml Yeast: 103 to 105 cfu/ml

  4. Trial 1: weaned piglets • Trial 1: 16 Dec ’10 • Fermentation 32 - 34 ˚C (warm water) • Batch fermentation • Daily cleaning hot water (60-70 ˚C) • Weekly sodium hydroxide + soap cleaning; hot water • Ferment mix: barley (62%), wheat (35,7%), molasses (2%), palm oil (0,3%) • Pellets, crumbled feed • Temperature of final diets are equal (computer controlled)!

  5. Trial 1: weaned piglets • Control: 65% non-fermented ferment mix + 35% conc. • Ferment: 65% fermented ferment mix + 35% conc. • Day 1 – 4: 90% prestarter + 10% ferment mix • Day 5 – 20: 65% ferment mix + 35% conc.1 • Day 21 – 35: 65% ferment mix + 35% conc.2 • 856 piglets: 16 replicates per treatment

  6. Trial 1: weaned piglets; day 1-35

  7. Trial 2: weaned piglets • Trial 2: 10 February – 16 March 2011 • Fermentation 32 - 34 ˚C (warm water) • Batch fermentation • Daily cleaning hot water (60-70 ˚C) • Weekly sodium hydroxide + soap cleaning; hot water • Ferment mix: barley (62%), wheat (35,7%), molasses (2%), palmoil (0,3%) • Pelleted, crumbled feed • Temperature of final diets are equal (computer controlled)!

  8. Trial 2: weaned piglets • Control: 65% non-fermented ferment mix + 35% conc. • Ferment: 65% fermented ferment mix + 35% conc. • Day 1 - 20: 65% ferment mix + 35% conc.1 • Day 21 – 35: 65% ferment mix + 35% conc.2 • 1.039 piglets: 20 replicates per treatment

  9. Trial 2: Weaned piglets; day 1-35

  10. Remarks: • Concentrates (35% of DM) are identical in both treatments • Concentrates includes “insurances” (i.e.. organic acid) • Difference trial 1 versus trial 2: • First 5 days after weaning both treatments got very luxury feed • First 5 days both groups (except 10% ferment mix was fermented versus non-fermented) was identical.
