Whey permeate
Whey permeate is a by-product of the production of whey protein concentrates, for example in the cheese industry. Whey permeate mainly contains lactose, minerals and traces of protein. It is often used as a filler or flavor carrier in the animal feed industry, for example for pet food, pig feed or milk replacer for calves. But is whey permeate also suitable for dogs and what are its advantages and disadvantages?
What is whey permeate and how is it produced?
Whey permeate is produced when the protein is removed from fresh pasteurized whey left over from cheese production. To do this, the whey is filtered through a membrane that only allows small molecules such as lactose and minerals to pass through. The retained protein is further processed into whey protein concentrate, which is used in sports nutrition or baby food, for example. The whey permeate that passes through is concentrated and dried in order to preserve and transport it.
What ingredients does whey permeate contain?
Whey permeate consists of about 75% lactose, a disaccharide of glucose and galactose. Lactose is the main component of milk and serves as a source of energy for mammals. Whey permeate also contains around 10% minerals such as calcium, phosphorus, magnesium, sodium, potassium and chloride. These are important for bone structure, nerve function and the body's water balance. The rest of whey permeate consists of water, traces of protein and other organic compounds.
What are the benefits of whey permeate for dogs?
Whey permeate can have several benefits for the health and well-being of dogs. For one, it can aid digestion by acting as a prebiotic. This means that it supports the growth of beneficial bacteria in the gut, which helps to maintain gut flora. These bacteria also produce short-chain fatty acids, which can protect the intestinal mucosa and inhibit inflammation. Secondly, whey permeate can increase the taste and acceptability of the food by adding a mild sweetness. This can be particularly helpful for picky or sick dogs that otherwise have little appetite.
What are the disadvantages of whey permeate for dogs?
Whey permeate also has some disadvantages for dogs that you should be aware of. Firstly, it can lead to an overdose of lactose if the dog consumes too much of it. Although lactose is a natural component of mother's milk, many dogs lose the ability to digest lactose in the course of their lives. This is because they no longer produce enough of the enzyme lactase, which breaks down lactose into glucose and galactose. If lactose enters the large intestine undigested, it can be fermented there by bacteria. This leads to flatulence, diarrhea and abdominal pain. Secondly, whey permeate can reduce the nutritional value of the feed by displacing other high-quality ingredients. Although whey permeate has a high energy content due to the lactose, it has a very low protein content. However, protein is essential for dogs as it forms the basis for muscles, skin, hair, the immune system and many other bodily functions. If the food contains too much whey permeate and too little protein, this can lead to deficiency symptoms and health problems.
Whey permeate is a by-product of whey protein production, consisting mainly of lactose and minerals. It can have some positive effects on digestion and the taste of the food, but also some negative consequences such as lactose intolerance and nutrient deficiencies. Therefore, whey permeate for dogs should only be used in moderation and attention should always be paid to the quality and composition of the food. If the dog shows signs of intolerance or deficiency, the food should be changed or a vet consulted.
If you notice any signs of hypersensitivity or poisoning in your dog, you should see your vet immediately. We are not a substitute for a vet, but we try to be as accurate as possible. Every dog reacts differently and we recommend you get a second opinion or consult your vet if in doubt.
Stay healthy and take good care of your four-legged friend!😊
