Methyl-sulphonyl-methane (MSM): This is an organic sulphur that’s natural derivative of pine bark. It has been recommended for the treatment and prevention of osteoarthritis and other joint problems due to its anti-inflammatory effect.
Nitrogen-free extract (NFE): In dog food and animal feeds this represents soluble carbohydrates and other digestible and easily utilisable non-nitrogenous substances.
Consisting of carbohydrates, sugars, starches, and a major portion of materials classed as hemicellulose (plant cells). This is calculated as a percentage by taking the total percentages of crude protein, fat, water, ash and fibre in the dog food from 100, what is left is the NFE %.
Non fibre carbohydrates (NFC): This is the highly digestible carbohydrate fraction of a food
consisting of starches, sugars, and pectin. As mentioned before fibre helps things pass through the digestive system and so this is the portion of the carbohydrates that are digestible.
Saturated and Unsaturated fatty acids: Fats are essentially long chains of carbon. Each Carbon has four bonds. Essentially every carbon bonds to the carbon in front and behind on the chain and leaves two ‘hands’ or bonds left. In fats these bond to hydrogen atoms.
When Every spare hand or bond is attached to a hydrogen atom the fat is considered a ‘Saturated’ or ‘Hydrogenated’ fat.
However sometimes two carbon atoms are very fond of each other and form a double bonds or ‘two hands’ between them in the chain. This means that not all the ‘hands’ or bonds are not attached to a hydrogen atom and therefore it is an unsaturated fat.
Saturated fats tend to be found in animal fats, dairy, coconut oil. Unsaturated fats are found in vegetable oils and fish like salmon and tuna. They include omega 3 and 6 fatty acids.
