RWN Calf Milk Replacers

Calf Milk Powder benefits over whole milk

Calf powder is cheaper than whole cows milk and gives better results. Waste milk should not be fed to dairy heifer calvesNumerous trials have demonstrated improved growth rates when calves are fed calf milk powder compared with feeding the same amount of solids in the form of whole cows milk.

Calf milk replacers are much more consistent, have added minerals and vitamins, are more digestible and have higher protein to fat ratios than whole milk. This results in faster growth rates, higher concentrate intakes and earlier rumen development.

Feeding milk replacer helps to minimise disease risk, in particular Johne’s disease. The use of waste milk also has the risk of antibiotic resistance and of feeding pathogens to the calves. This practice should be discouraged especially with calves intended to become dairy heifer replacements.

Calf milk powder has a lower cost per litre than saleable whole milk.

What to look for in a Calf Milk Powder?

The quality of milk powders varies enormously. Our advice purchase from the high quality end of the market place. Price should not be the main deciding factors. Your calves are your future dairy herdWhilst most calf milk powders look the same the quality of ingredients vary enormously. It is very difficult to distinguish between a quality product and a budget product made to a price. A wide range of ingredients can be used including skim, casein, buttermilk, whey, whey protein concentrate, soya and wheat, potato, pea protein concentrates together with a wide range of fats and oils.

The cheapest milk powders available are about half the price of the best quality products. The ticket declarations are of little help and all product have a similar appearance - a creamy white powder.

Whey and vegetable proteins are much cheaper but skim, casein and buttermilk based products are digested much more efficiently. This is due to there ability to form a clot in the abomasum. The pH around the clot is at very low pH allowing the enzyme pepsin to efficiently digest the milk. Different sources of skim, or whey can vary enormously in feed value depending on how they were produced and how much protein was denatured during the drying process. Generally the higher the level of milk products in the milk powder the better.

Avoid low quality calf milk replacers made to a price. Use only the best, these calves are your future dairy herdThe difficulty of distinguishing a quality calf milk powder from a budget product has meant that it has been much easier for manufacturers to sell products made to a price. Not surprisingly then most of the UK market is for whey and vegetable protein based products which contain no skim, casein or buttermilk.

Whey and vegetable protein products are generally lower in energy and are digested less well. This can result in faster uptake of dry feed so these low cost calf milk replacers do have a place.

However generally we see better growth rates with far fewer health problems when 'high quality' milk powders are used rather than calf powders made to a price.

Never skimp on the quality of calf milk powder for dairy heifers

The benefits of doing calves well should never be under estimated. An analysis on data from the Cornell herd of 1,244 heifers showed that every kg of average daily gain prior to weaning resulted in a milk yield increase of over 2,200 kg milk over 3 lactations. In addition 22% of the variation in first lactation milk production could be explained by growth rate prior to weaning. This demonstrates that it is never worth economising by using anything other than the best quality calf milk powder.

1kg extra weight gain pre-weaning = 2200 extra lifetime milk yield

Most Cost Effective for Rearing Calves?

So which is the most cost effective route? Well it depends. It depends on the rearing system that you are using and on your expectations. Are you producing a replacement heifer, the future of your herd? Are you producing a beef calf that you want to top the market? Are you producing a beef animal destined for slaughter? Are you contracting rearing to a price?

Not all milk replacers are equal. Using a better quality replacer will often reduce costs overall. Quality is far more important than price per tonne.Higher quality products tend to be higher in energy with better digestibility and can often be fed at higher rates earlier without causing digestive upsets and nutritional scour. Thus higher live weight gains can be achieved.

Our view is that the best calf milk powders generally give better results and can often be cheaper to use in the long run, due to faster growth rates, lower mortality, lower vet bills, earlier weaning, reduced milk used and higher lifetime yields.

There is no question that dairy heifer calves which get off to a good start are capable of producing higher lifetime milk yields and that replacement cost per litre can be reduced by doing calves better.

Doing heifer calves well can result in
reduced dairy heifer replacement costs and increased lifetime milk yields

Equally I have seen dairy units producing bull calves to sell at a few weeks old, halve their powder and straw usage, halve their stocking rate, dramatically reduce labour costs, vet bills and mortality and improve there sale price simply by switching to a better milk powder.

Feeding top quality milk replacer is often costs less overall

Elite Calf Milk Replacer is an exceptional powder formulated using skim to give calves bloom. Elite gives superb results both with calves marketed at 2 - 5 weeks of age or with dairy heifer replacements. Elite is a superb product for use in both twice day bucket feeding systems, once a day feeding systems and in computerised calf feeders. A great calf milk powder.

Extremely high quality calf powder at a very competitive price

Calves fed on a specialist calf milk replacer once a day perform better with fewer problemsElite is one of the best calf powders that we have seen and at a very competitive price.

Elite produces excellent results on Once a Day feeding systems. Being skim based it has the ability to form a clot in the abomasum which is digested slowly and efficiently over 6 - 8 hours. This avoids the problems associated with most calf milk replacers which are based on whey powder or vegetable protein and which are generally much less effective when used in Once a Day feeding milk systems.

Elite is an excellent alternative to Shine Once A Day at a Lower Price

For most dairy farmers the Once-a-Day milk feeding system has clear advantages over other feeding systemsShine Once a Day

The pioneer of once a day feeding, with butter milk and skim milk powder, it can be fed with water or milk to reduce your work-load but not compromise the calf. Once-a-Day feeding is a system which can deliver performance benefits over twice-a-day feeding for much less labour and less cost.

Feeding Once-a-Day is simple. 200gms of powder is made up to 1 litre with water or 60 - 100gms of powder made up to 1 litre with cows milk. Three litres of milk can then be fed straight through to start of weaning at seven weeks and then reduced by half a litre per day to wean at 8 weeks.

There’s plenty of research around that shows that calves can be fed successfully on once-a-day milk feeding systems. Once-a-Day feeding involves significantly less labour, uses less calf milk replacer and promotes earlier weaning whilst resulting in improved growth rates and healthier calves.

Switching from a twice-a-day milk feeding system to once-a-day could save UK calf rearers around £6/calf and cut labour input to as little as 23 seconds/calf/day.

Once a Day Feeding of Milk has many advantages and cows perform better than on twice a day. They key is in the quality of the powder. Don't be tempted to try Once a Day feeding with whole milk or standard calf milk replacersThis milk powder has been shown to give live weight gains up to 12% higher than feeding twice daily whole milk, and can reduce your work load by up to 40%.

Once daily feeding is best suited to calf milk replacers based on skim milk powder. This is because skimmed milk forms a cheesy curd or clot in the calf’s stomach that takes over 14 hours to be digested. This clot forms using casein protein produced in the cow’s udder specifically for the calf.

Milk replacers that claim to contain milk, but make no reference to skim milk powder or buttermilk are unsuitable for once-a-day feeding at an early age since they contain no casein protein, and will not form a slowly digested clot in the calf's stomach.

All calves must be fed twice a day. Feeds may consist of either two feeds of milk or milk fed in the morning followed by dry feed in the evening. Once daily milk feeding should only be introduced once calves are capable of eating a feed of dry concentrates later in the day.

Healthy Calves grow rapidly. Well grown heifers have higher lifetime milk yieldsWhole milk is unsuitable for Once-a-Day feeding since milk solids need to be at least 20% in order to get sufficient solids into a single milk feed. However whole milk with 50 - 100gms of milk powder added can be used successfully in a once a day system.

With the right milk replacer, a once-a-day milk feeding system works extremely well for both the calf and the rearer.

Apart from the obvious labour benefits, calves eat more dry feed and their rumens develop more quickly. This allows weaning to occur a week or two earlier, both saving labour and cutting the amount of milk replacer used. Most importantly calves actually do better.
