Dogs One of the key indicators of the health of the dog is the dog's fur. There are many factors for dog hair, such as the dog's malnutrition or the dog's age, etc. are important factors for dog hair. According to medical theory, dog nutrition has an important impact on dog hair, then What nutrients do dogs need to regulate their hair?

First, the nutritional needs of dogs

Excessive or unbalanced food intake in dogs can lead to obesity, which can lead to many diseases, so it is important to regulate your dog's food intake. Under normal circumstances, dogs should be rationed and adjusted from time to time, especially those dogs that are prone to obesity. Table 1 shows the metabolizable energy required for dogs per kilogram of metabolic body weight per day. The dog's metabolic body weight is generally expressed by W0.67: W is the body weight (kg). Therefore, when producing dog food, the metabolizable energy per kilogram of dog food should be indicated.

Like other animals, dogs' caloric needs are also affected by various factors, such as body size, weight, age, temperature, growth stage , coat condition, amount of exercise and workload, etc.

The canine nutritional requirements standard published by the Canine Nutrition Committee (CNE) of the American Association of Feed Supervisors (AAFCO), adopted by many pet food manufacturers, divides the nutritional stages of dogs into growth and breeding periods and adult dog maintenance period (Table 2), (assuming that the ME of dog food is 3.5kcal/g DM, more than 4.0 kcal/g DM should be adjusted according to the proportion).

Second, nutritional deficiencies

Generally, when animals are deficient in protein, amino acids, linolenic acid, certain minerals, VA and certain VB At this time, the condition of the fur will be affected, and the quality of the feed raw materials will also reduce the biological potency of some important nutrients, resulting in a decline in the color and quality of pet fur.

1. Protein deficiency

Protein deficiency will lead to abnormal keratinization of the fur, making the skin vulnerable to damage, thinning, fading, and breakage, growth Slowed or even stopped, the fat layer of the epidermis is damaged, resulting in scaly, greasy skin. The amino acid that is higher in fur protein is the sulfur-containing cystine, and a lack of sulfur-containing amino acids in dog food can often lead to coat problems.

2. Fat deficiency

Low-fat diets can lead to dull coats, dry, scaly skin, and fat-soluble vitamin deficiencies that affect growth , increased mortality in severe cases.
