Buying food for your Mastiff, please pay attention to:
a) the originality of the package;
b) the obligatory presence of the instruction in your mother tongue;
c) the airtightness of the package (defects are unacceptable);
d) the date of manufacture and expiration date;
e) the ingredients of the feed;
f) the presence of preserving and colouring agents.
The package should contain the list of ingredients involved in its preparation (manufacturers usually do not specify their quantity, keeping the trade secret), as well as the content of main nutrients (proteins, fats, carbohydrates), and sometimes the presence of dietary fibers, mineral substances and the ratio between calcium and phosphorus (Ca: P), vitamins (unless their quantity is not specified, it is assumed that their content should be not less than normal), sometimes the content of biologically active substances is also indicated.
Most companies that produce food, are silent about the used preserving and colouring agents, aromatic and flavour additives.
Premium and superpremium class feed often do not contain flavour and aromatic chemical additives and usually there used natural colouring agents similar to those used in the food industry, but the preserving agents should be natural (vitamins C, E, etc.). Since these feeds do not contain additives that lure the dogs, they refuse from this food more often than from lower quality feeds, which contain aforementioned additives.
During heat treatment of raw materials for feed, physiologically active substances (enzymes, hormone-like substances, inhibitors) are destroyed and this lowers the digestibility of feed components and increases the burden on the digestive tract.
This explains the diarrhea, disbacteriosis phenomena, disorders of the digestive and other phenomena associated with abrupt change of feed or with a sharp transition from natural food to dry food.
In the process of production, once the high quality forage food is ready, the feed is sprayed by a complex of physiologically active substances and temperature unstable vitamins. This technique significantly increases the digestibility of feed, but used by few companies.
The ingredients on the package are usually indicated in descending order depending on their quantity, and one should pay attention to this issue in the process of choosing a type of feed. It is more desirable to choose feeds, which have animal products at the head of the list. However, even if using one sort of meat and several kinds of cereals, meat may be at the head of the list, although its mass portion is smaller than grains in the aggregate.
You should give preference to the forage, where there are several varieties of meat and a few kinds of cereals.
For breeding animals it is not desirable to use feed, comprising a large percentage of soy or soy products.
