1. Product presentation calf 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 Number of calvesWithout signs of disease With signs of disease Pasteurized milk (trial group) 1810 = 56 % 8 = 44 % Not pasteurized milk (control group) 153 = 20 % 12 = 80 %

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 Reduction of the IgG level65°C, 30 min.72°C, 15 sec. First colostrum58%34% Second colostrum45%28%
