1. Sprayfo Life Start validation

2. Dairy sector is facing a challenge
Demand for milk growing worldwide
Sustainability & durability are issues of today
Animal welfare coming up
Dairy farms are scaling up
Genetic potential of dairy cows develops fast
Sexed semen, genomic, marking, etc.
So: Potential and value of young calf is growing

3. Farmers want to be good farmers
Manage the farm the best way to
Earn a fair income today
Be prepared to earn a fair income in the future
Have work well organised
Have satisfied employees, suppliers and buyers.
Have a happy and healthy dairy herd
Make use of the potential of their animals

4. Still we are facing a problem
Average mortality in first year still >10%
Growth potential of calves still not used
Farmers know, but
mismatch between knowledge and behaviour

5. Issues we face in daily practice
Big differences in colostrum application
Often milkfeeding to low to match calf requirements
Especially in first 3-4 weeks
Some still feed discarted milk to calves
Time of weaning managed poor
Housing calves not growing in line with rest of farm

6. Farmers need to make a choice!
Be aware and choose to:
Let young calves survive at the lowest cost or:
Apply available tools to grow the best valves and develop the best heifers!

7. Sprayfo has part of the solution
Use options in feeding and management to develop the full expression of genetic potential
Realise the best calf rearing
To achive the ultimate dairy cow performance
 Longer lifetime + higher milkproduction

8. Maximum (udder) tissue development
Maximum youth growth & minimal disease
Maximum (udder) tissue development
Optimal development of immune & digestive system
More sustainable dairy farming!
Lower mortality
Increased milk yields
Lower culling rates
Full expression of genetic quality

9. No false claims,
but proven results

10. Early growth sets life performance

R784 : High protein +/- 0

R817 : Late weaning + 3 kg
R841 : HD 9 weeks + 8 kg
V839 : veal powerstart + 5 kg (in 4 weeks!)

20. What to do with this? Develop the best calf rearing program
Growth steers intake of compound feed
Good CMR  more growth  more CF
Early weaning not preferred; 9 weeks OK
High density preferred, esp. in first 5 weeks
High protein in CMR not needed

21. Apply Life Start Concept to get 3 plus !
Growth of > 900 gram/day in first 3 months is possible
Apply the right concept farmers get 3 plusses:
+ 50% mammary development
+ 9% milk production
+ 47% durability of dairy cows
