Sprayfo Delta high fat calf milk replacer mixes the best of whole milk with the best of calf milk replacers (CMRs), providing all the benefits of whole milk feeding with guaranteed consistency.
High energy curding CMR for optimal performance and fast growth rates
Improves future robustness of the animal
Osmolality similar to cow’s milk - improves digestion and reduces risk of scours
>95% digestibility
Balanced mineral composition to meet calf requirements
Optimises organ development, especially of the mammary gland parenchymal tissue
Improves long term productivity – increased meat yield for beef, more lactations for dairy
Consistent quality and composition from batch to batch
Sprayfo Delta calf milk replacer is a curding (casein-based) product, scientifically formulated for performance and growth. We call it energised calf milk.
What makes Sprayfo Delta your best choice of calf milk replacer?
Based on the composition of whole milk, Sprayfo Delta is higher in fat than any other CMR available in New Zealand. It also contains a balanced nutrient supply (vitamins and minerals) for optimal growth and development.
The true measure of a quality CMR is the ability of the young calf to absorb nutrients contained in the CMR and to use these for growth and development. Sprayfo Delta is highly digestible, meaning you get better value for your money.
The osmolality of cow’s milk (whole milk) is close to 300mOsm/kg, which is optimal for the absorption and digestion of nutrients by calves.
Sprayfo Delta has an osmolality of 350mOsm/kg when mixed at the recommended rate of 135g/L. In contrast, other milk replacers have levels about 400mOsm/kg, some closer to 600mOsm.
A milk replacer with high osmolality (above 500mOsm/kg) may affect osmosis and hence present challenges to calves, including scouring and inflammation of the gut.
Comparative trial: Sprayfo Delta vs standard (casein-based) CMR
One group of 15 calves was fed whole milk for the first 20 days of their lives, followed by feeding with Sprayfo Delta high fat milk replacer until they were weaned at 10 weeks of age.
A control group of 14 calves was fed according to the same schedule with a standard (casein-based) CMR.
Note:
Both sets of calves were fed the same quantity of CMR (in litres) to day 28.
In fact, Sprayfo Delta was fed at a lower concentration than the standard CMR during weeks 4-5.
Conclusion
During the first 3 weeks, when both groups were on whole milk, there was no difference in growth. Once the calves were switched to CMR, the group being fed Sprayfo Delta grew faster, adding almost 200g more per day.
The higher rate of growth is ideal for beef rearers wanting to hit weaning/sale targets quicker. While dairy farmers will benefit from fast growing, robust calves with optimal organ and cell development, making better producers in the long term.
