Husky (certain introduction)

Like other animals, dogs must have nutrients as material conditions to maintain their growth, development, growth and other life activities. Water, protein, fat and carbohydrates are essential for their growth and development. Life circulation plays a very important role. The water content of an adult dog's body is 6O%, and that of a puppy is even higher. Therefore, water is the prerequisite for the survival of dog life.

　(l) Water

The body of adult dogs contains 60% water, and the water content of puppies is even higher. Therefore, water is the prerequisite for the survival of dog life. The water in the cells and cell walls of the dog's body regulates osmotic pressure and surface tension to maintain the normal state of the dog's body. The absorption, transportation, and metabolism of nutrients all require water, and the regulation of dog body temperature also depends on water.

If the water content in a dog's body decreases by 5% to 8%, it will cause thirst, irritability, loss of appetite, delayed digestion, and susceptibility to infectious diseases. When the water shortage reaches 20%, it may lead to death.

Under normal circumstances, adult dogs need 100 ml of water per kilogram of body weight per day, and puppies need about 150 ml of water per kilogram of body weight per day. Therefore, dogs should be provided with sufficient drinking water when raising them, especially in hot seasons, after exercise, and when feeding tougher feeds, the amount of water they drink should be reduced.

　(2) Protein

Protein is the prerequisite for life movement in dogs. It constitutes various tissues and organs in the dog's body and various enzymes for material metabolism. .The antibodies that give the body immunity are also made of proteins.

Protein is composed of amino acids, which are divided into essential amino acids and non-essential amino acids. To evaluate feed protein, we must not only look at its quantity, but also its formation.

Dogs lack protein, resulting in slow growth, poor development, delayed sexual maturity, reduced sexual desire in male dogs, reduced breeding ability, reduced postpartum lactation in female dogs, and even fetal abnormalities and stillbirths. . Therefore, dogs should be fed adequate amounts of protein, but there is no right amount.

Under normal circumstances, adult dogs need 5 grams of protein per kilogram of body weight per day, and puppies in the growth and development period need 9.6 to 10 grams.

　(3) Fat

Fat is required for large bodyIt is a harmful factor, and its content is 10% to 20% of body weight. It plays a key role in the growth and development of dogs.

Fat is involved in cell formation and repair; fat is also a solvent for fat-soluble vitamins and can promote the absorption of vitamins A, D, K, etc.; fat is also an important source and storage method of energy in the dog body.

The fat required by the dog’s body is mainly supplied by feed. Generally, adult dogs need 1 gram of fat per kilogram of body weight per day. If the supply of fat is insufficient, it will lead to vitamin deficiency, slow the growth of the dog, and hinder sexual maturity; while too much fat will affect the intake of other nutrients, cause loss of appetite, indigestion and diarrhea, and harm the function of internal organs.

　(4) Carbohydrates

Carbohydrates are mainly used to supply energy and help fat oxidation in the dog body. Therefore, when there is a lack of fat, the dog will experience weakness, a sharp drop in body weight, and serious obstacles in growth; however, too much will lead to a large amount of fat accumulation and transfer to fat, making the dog obese.

Under normal circumstances, adult dogs require 75% of their daily carbohydrates, and puppies require 17.6 grams per kilogram of body weight per day.
