1. The global farming challenge
Natural, sustainable methods of improving health and productivity are required
• Nine billion people to feed by 2050
• Pressure to become more sustainable
• Drive to improve animal welfare and health
![Page 5: Harnessing the power of nature - Lifestart · 2015. 1. 30. · Moallem, D. Werner, H. Lehrer, M. Zachut, L. Livshitz, S. Yakoby, and A. Shamay, 2010, Long-term effects of ad libitum](https://reader033.vdocuments.us/reader033/viewer/2022051902/5ff1db1c8aa5ac1d0d00d2f3/html5/thumbnails/5.jpg)
LifeStart
• Natural and sustainable method for rearing more productive cows
• Potential to improve health and reduce costly interventions
• Dedicated to developing farming protocols and the science behind them

Your future as a cow is dictated by what and how much you eat as a young calf
”Early calf nutrition management can program the metabolism of the cow and help to determine life productivity.”
Fernando Soberon PhD, Technical Services Manager, Shur-Gain USA

The LifeStart phenomenon
• Metabolic programming happens in nature
• Caused by availability of quality food in early life
• Results in whole life health and performance at ”full potential”
![Page 8: Harnessing the power of nature - Lifestart · 2015. 1. 30. · Moallem, D. Werner, H. Lehrer, M. Zachut, L. Livshitz, S. Yakoby, and A. Shamay, 2010, Long-term effects of ad libitum](https://reader033.vdocuments.us/reader033/viewer/2022051902/5ff1db1c8aa5ac1d0d00d2f3/html5/thumbnails/8.jpg)
Metabolic programming
• Thought to be caused by epigenetics...
• ...the expression of genes outside the genome
• Precise mechanism not known but is being investigated by new LifeStart trials
![Page 9: Harnessing the power of nature - Lifestart · 2015. 1. 30. · Moallem, D. Werner, H. Lehrer, M. Zachut, L. Livshitz, S. Yakoby, and A. Shamay, 2010, Long-term effects of ad libitum](https://reader033.vdocuments.us/reader033/viewer/2022051902/5ff1db1c8aa5ac1d0d00d2f3/html5/thumbnails/9.jpg)
The critical window of opportunity
• The first 8-9 weeks of pre-weaning period is critical
• Careful management is the key
• Virtuous circle of good health, quality nutrition and strong growth
![Page 10: Harnessing the power of nature - Lifestart · 2015. 1. 30. · Moallem, D. Werner, H. Lehrer, M. Zachut, L. Livshitz, S. Yakoby, and A.

5 critical control points
Cleanliness – hygienic birth and housing
Colostrum – 4 litres in the first 6 hours
Comfort – dry, bright, soft, well ventilated
Calories – 150g/litre of LifeStart approved CMR
Consistency – feed according to a schedule

Where LifeStart makes the difference
“Raising calves is a huge opportunity to reduce workload and costs caused by unhealthy animals and to boost the productivity of individual cows.” Dr Klaus Daubinger, Calf rearing expert

Feed rates for quality heifers...
• 150g/litre x 6 litres/day
• LifeStart milk replacer for 40-42 days then start to reduce levels gradually to wean at 70 days
• 6 litres/calf/day x 150g/litre = 900g powder/day

The LifeStart promise to farmers
4 litres/gram
Referencing the studies summarized previously where milk production is increased by proper colostrum administrations in the first hour as well as increased ADG pre-weaning, the LifeStart Program aims to deliver an average first lactation increase of 4 litres per gram of growth.
