Sprayfo and cow’s milk

1. Sprayfo and cow’s milk

2. Content Cow’s milk on dairy farm Feeding cow’s milk to rearing calves Cow’s milk Calf Milk Replacer Management of rest milk Conclusions

3. Cow’s milk on a dairy farm Cow’s milk is produced for delivery to milk processing industry Sales of cow’s milk = basic income for dairy farm Cow’s milk of first 2-3 days after calving is undeliverable Milk of cows treated with antibiotics is undeliverable Undeliverable milk = rest milk Farmers prefer not to dump rest milk Feeding cow’s milk to calves seems easy and cheap

4. Feeding cow’s milk to rearing calves

5. Advantages of cow’s milk Cow’s milk tastes good, is well-accepted by calves high intake of cow’s milk slows down intake of concentrates Cow’s milk is easy to supply correct execution means more manual work Calves on cow’s milk look good Only optical:because of shine (high fat) and filling (rennet) Dumping rest milk is financial loss is correct, but can be approached differently: Better management of rest milk (later)

6. Disadvantages of cow’s milk Cow’s milk may contain harmful pathogens Transmission of Para-tbc on other threats Penicillin milk contains antibiotics  Create resistance of dairy cows against penicillin Cow’s milk is too fat slows down rumen development, insufficient growth after weaning Cow’s milk is low in vitamins and trace elements  More anemia and weaker bone structure

7. Creative with cow’s milk? Too much fat dilute milk with waterconsequence: less vitamins and trace elements Too much fat skim the cream off the whole milkconsequence: less fat-soluble vitamins Labour involved = too much manual work on large farms Simple calculation:For feeding 50 calves = transport 15,000 litres of cow milk = poor 80 bags of calf milk replacer in an automatic drinking machine

8. Cow’s milk compared to calf milk replacer

9. Cow’s milk is variable Variable nutrients  variable growth  more diarrhoea Source: Sloten 2010

10. Cow’s milk is not balanced

11. Calves on cow’s milk low in iron 182 bull calves to trial farm Sloten in 2009 Age at arrival: over 2 weeks At arrival all calves tested on Hb value (standard) Bull calves most fed with cow’s milk Minimum – reference Hb value is 10.5 mg / 100 ml Average Hb value is 8.8  TOO LOW ! 20% meets standard > 10.5 46% too low 8 – 10.5 34% critically low < 8

12. Cow’s milk results in anaemia! Spread of Hb value in starting calves 46% Too low ! 34% critical low ! 20% above norm number of calves Hb value

13. Trial on feeding cow’s milk Source: Hill et al., 2007

14. Watch out with feeding too much milk Milk only  Low concentrate intake  Bad rumen development

15. Management of rest milk

16. Feed rest milk to calves for sale Conclusion: In theory, a farmer does not have a surplus of rest milk

17. Too much rest milk? Different challenge! Conclusion: Farmer with too much rest milk has a different challenge

18. Conclusions

19. Sprayfo made for calf rearing

20. Sprayfo better for calf rearing Safer constant composition, less chance of diarrhoea with Safety Packege and/or specific antibodies Healthier added iron and vitamins composition enhances intake concentrates less transmission of diseases (such as Para-tbc) Simpler to feed calves irrespective of milking time especially in case of automatic feeding less diarrhoea problems  ANDa higher profit per dairy cow!

21. Sprayfo brings higher profit Cost price per litre Sprayfo is lower than 20 cents Sales price per litre cow’s milk is more than 25 cents In short:  Sell cow’s milk for highest profit  Including package of advantages: growth, health, durability and milk production in future
