Energy Sources
Originally, dog owners who fed their pets natural ingredients were attempting to restore the natural diet of the dog. Natural ingredients used nowadays are no longer the foods eaten by an animal ”naturally” in the wild, but have turn into modifications of those original products to more confinement or longer-lasting forms.
The human diet consists of a big selection of such customized natural foods, most of which have been tried for feeding a dog. Besides these human foods, there are still a few natural ingredients accessible to the dog owner that are not usually considered to be human foods. Examples of such foods are horse meat, hog livers, and bone meal.
Meat is, without question, the most ordinary natural ingredient fed to a dog. It is also the most widespread source of protein. It is not the only source, nevertheless, nor is it the best. Eggs, milk, and plant proteins also make up a big reservoir of protein sources available to dog feeders.
All natural foods containing nutrients are energy sources, because most nutrients can grow to be energy. Some natural foods supply more energy than others and are customarily used as energy sources. These are the foods containing the major quantities of fats and carbohydrates. Fats are the main energy source in any diet for a dog. Most meats come with the fat already attached, particularly in the chopped and ground varieties. Fats also can be found in nature in the pure form as vegetable oils or as tallow and lard.
Carbohydrates, while not as concentrated an energy source as fats, are lower in cost. Carbohydrates are functional to weaken the protein in high-meat diets or lower the caloric density of diets containing too much fat.
Most likely the most universally functional source of energy for a dog is corn oil. Corn oil supplies 9 calories in every gram, 250 calories in each ounce, 124 calories in each tablespoonful, and 62 calories in every teaspoonful. When used as the only fat in a food it also furnishes about ten times the amount of vital fatty acids required by a dog. Corn oil is cheap, easily obtainable, and has a logically good keeping quality. Other vegetable oils that can be used adequately as an energy source for a dog are olive oil, peanut oil, safflower oil and soybean oil.
