Sprayfo Blue whey-based milk replacer is a cost effective, high-quality source of the essential nutrients required by rapidly growing young calves. Suitable for calves from 3-4 days old in New Zealand.
Sprayfo Blue is based on unique spray-dried whey-fat kernels.
Non-curding but specifically formulated for growing calves, it contains hydrolysed wheat protein, which has been shown to offer better digestive properties than other commonly used protein sources such as soy. That makes it a safer option for young calves during the early stages of life.
Sprayfo Blue gives you flexibility on farm.
It can be fed as the sole milk source, or used to fortify and enrich cow’s milk when you want to lift the plane of nutrition, or used later on as a calf finisher.
Added Support for Gut Health and Immunity
Sprayfo Blue includes prebiotics, probiotics, organic acids, and natural vitamin E. These components are included to support gut health and overall calf development.
As with any calf rearing programme, calves should receive high quality colostrum within the first 12 hours of life, followed by colostrum milk for the first 3 to 4 days to help strengthen their natural immune system before transitioning onto milk replacer.

What are the Benefits of a Whey-based Calf Milk Replacer?
1. Whey is easy to digest
Quality whey-based formulas are easily digested in the gut, moving through a calf in only 2-3 hours, compared to 5-8 hours for traditional curding (casein) formulas.
2. Whey is cost-effective
With whey powders moving through an animal’s system in 2-3 hours, they will seek out concentrates (meal) sooner.
- Early intake of concentrates helps to encourage early rumen development, allowing calves to more effectively utilise cheaper feed sources, sooner.
- Whey powders can be mixed with whole milk (commonly known as fortifying), increasing its flexibility as a replacer.
3. Whey helps the weaning process
Animals reared on whey-based powders develop their rumen quicker, handling the transition through weaning with a reduced risk of the growth check common in stock reared on curding powder.
- Early rumen development is essential for profitable animal rearing.
- Rearers report less stress and continued strong growth rates, making for healthier, bigger, well-conditioned young stock.
