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: Let young calves survive at the lowest cost or: Apply available tools to grow the best valves and develop the best heifers!

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

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

No false claims, but proven results

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
