Product presentation calf milk pasteurizer “MaxiSteam II” Functions – Specification – Technical data

1. Product presentationcalf milk pasteurizer “MaxiSteam II” Functions – Specification – Technical data Engen, July 2008 Kathrin Aymanns

2. Background • Feeding of fresh milk gets more and more important (MR prices increases; non marketable milk) • Pasteurization is important to feed the milk without concerns • Especially for non-marketable milk (Mastitis milk) • Reduction of the germ content • Improvement of the animal health • Not clear: kill of Para tuberculosis germ • Difficult up to now: pasteurization of colostrum and mixed colostrum (sticking of plate pasteurizers, scorch in batch pasteurizers)

3. Animal development • Thesis of F. Schwab, FH Weihenstephan (2006) • Calves with and without sign of disease

4. Animal development – MR vs. pasteurized milk • Sandra Godden, field study, Minnesota 2002 • 10 month field study with 439 calves • Test group: 217 calves, fed with pasteurized, non-marketable milk • Control group: 222 calves fed with 20:20 MR • The calves who gets just pasteurized milk, arrived • higher final weights (147.3 lbs vs. 143 lbs after weaning) • higher daily weight gain(1.04 lbs/day vs. 0.76 lbs/day) • significant deeper death losses (2.3% vs. 11.6%)

5. Animal development – Raw milk vs. pasteurized milk • Jamaluddin et al., field study, California 1996 • Study with 300 calves • Calves fed with pasteurized colostrum and milk • were less days sick • had a reduced mortality rate • needed less funds for medicine • had higher weight gains after weaning • made a higher profit • than calves fed with non-pasteurized non-marketable milk

10. Product features MaxiSteam • Processing every milk type by steam pasteurization, e.g. • Whole milk • Non marketable milk • Mixed colostrum • High flexibility by pasteurization small portions, thus suitable for • small and daily changing quantities • growing farms • Quick heating and cooling of the milk ensures gentle processing

11. Product features MaxiSteam • Easily adjustable and controlled operating conditions by processor control (pasteurization temperature, hold time, etc.) – high process automation e.g. by electrodes in the milk tanks • End product ready to be fed thanks to integrated cooling system • Automated cleaning • Extras and accessories: • Water softener • Dosing pump for milk additives, e.g. acid for milk preservation or enhancement of digestibility • External steam distributor with pistol grip

12. Reduction of the germ content • Institute for Hygiene and Food Safety of the Federal Dairy Research Center in Kiel (Germany) 2007 • MaxiSteam I under laboratory conditions • All main Mastitis pathogens which might be transferred to the calf by the milk are significantly reduced.  95 – 99% reduction of the main germ content • Staphylococcus and Enterococci germs are lowered at least 5 log-10-steps (1:100.000). • CNS, yeast and Streptococcus could not even been found after pasteurization. • One very thermo tolerant E.coli germ reached almost 5 log-10-steps-reduction.

13. „gentle heating“ • Max Rubner Institut, BFEL in Kiel, Dr. Clawin-Rädecker, 2008 • Furosin is a sensitive heating indicator • It can be used to evaluate a pasteurization process • During the MaxiSteam test the furosin level doesn't increase  very gentle heating

14. Reduction of the IgG Level in colostrum • Department for veterinary research University Munich, 2008 • Method: Sandwich-Elisa; IgG-Bovin
