Water, fat, carbohydrates, minerals, cellulose, protein and vitamins were necessary to maintain the normal life and activities of a dog.
1. Water. In dogs, the water content in blood accounts for more than 80%; the water content in muscles accounts for about 72-78%; the water content in bones accounts for about 45%. Dogs need more water than food. There is no special water storage organ in dogs. The source of water in dogs is mainly from feed water and direct drinking water, so as to achieve the balance of water needed in dogs. The daily water requirement for adult dogs is 100ml / kg body weight, and for puppies is 150ml / kg body weight.
2. Fat. Fat is an important part of life organism, its main function is to store energy. Each gram of fat can produce 9.4 kilocalories after decomposition, which is higher than the energy of sugars and proteins. The energy in fat can’t be absorbed by dogs directly. It must be converted into fatty acids to be absorbed. Fatty acids play an important role in canine somatic cell membrane, reproductive organs and hormones. However, linoleic acid and peanut oleic acid can not be synthesized by themselves in dogs, but should be obtained from feed. Dogs are easy to absorb saturated fatty acids in animal feed, but it is difficult to absorb unsaturated fatty acids in plant feed. Therefore, if the dog is fed with plant-based feed for a long time, it will lead to malnutrition.
3. Carbohydrate. Carbohydrate, commonly known as sugar. In dogs, the main energy source of life activities is glucose, which can be quickly absorbed by dogs. Glucose is always maintained at a certain level in the dog’s blood to maintain the energy required by the dog’s internal organs.
4. Minerals. Minerals refer to other metal elements except carbon, hydrogen and oxygen in dogs. Minerals such as calcium, phosphorus, sodium, potassium, magnesium and so on are the main ingredients for dog nutrition. Minerals such as iron, zinc, iodine, manganese, selenium and so on, they are less in dogs. Although minerals are small in dogs, they play an important role in hormone level, soft tissue, blood, body flow and cells. And it directly affects the conduction function of the nervous system.
5. Cellulose. Appropriate amount of cellulose can promote gastrointestinal peristalsis, which is conducive to digestion. Cellulose is widely found in plant feed.
6. Protein. Protein is the main active substance of life activities, and also the main nutrient substance of life activities. In the dog’s life, it is the most critical stage of development when the dog is young, and the protein demand is the largest; in the adult, the protein demand tends to be stable. So in dog food, the animal feed should not be less than 30%. For some valuable dog species (such as police dog, anti drug dog, anti explosive dog, etc.), the proportion of animal feed should be increased. Four grams of digestible protein per kilogram per day is required for adult dogs.
7. Vitamin is an organic compound with high biological activity, which can not be synthesized or rarely synthesized in vivo. In the absence of certain vitamins, the synthesis of organic compounds in dogs will be stopped, which will cause certain diseases in dogs. All kinds of vitamins contained in dog feed are generally enough for dog body.
Balanced nutrition is one of the necessary conditions for healthy growth of dogs.
