Sprayfo Life Start validation

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

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

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

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

Farmers need to make a choice!

Be aware and choose to:

1. Let young calves survive at the lowest cost

or:

2. Apply available tools to grow the best valves and develop the best heifers!

Sprayfo has part of the solution

Use options in feeding andmanagement to develop the fullexpression of genetic potential

Realise the best calf rearing

To achive the ultimate dairy cow performance

Longer lifetime + higher milkproduction

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

No false claims,

but proven results

Early growth sets life performance

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

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
