One of the key signs of healthy dog ​​breeding is the dog's coat. The dog's hair can't help but affect the dog's appearance and can also reflect the dog's health. However, there are many factors that affect the dog's hair. For example, the dog's hair Malnutrition or the age of the dog are all important factors that affect the dog's hair. According to medical theory, the dog's nutrition has an important impact on the dog's hair. So what nutrients are needed to regulate the dog's hair? ?

1. Nutritional needs of dogs

Excessive or unbalanced food intake in dogs can lead to obesity, which can lead to many diseases, so it is very important to regulate the dog's food intake. In general, dogs should be given a ration of food from an early age and make adjustments at any time, especially those dogs that are prone to becoming overweight. Table 1 shows the metabolizable energy required by dogs per kilogram of body weight per day. The metabolic weight of dogs is generally expressed as W0.67: W is body weight (kg). Therefore, when producing dog feed, the metabolizable energy per kilogram of dog feed must be indicated.

The energy requirement of pet dogs is Kcal/W0.67/d

Like other animals, dogs' demand for heat energy is also affected by various factors, such as size, weight, age, temperature, growth stage, coat condition, amount of exercise and workload, etc.

The nutritional requirements standards for dogs published by the Canine Nutrition Committee (CNE) of the Association of American Feed Controllers (AAFCO) are adopted by many pet food manufacturers. It divides the nutritional stages of dogs into two stages: the growth and breeding period and the adult dog maintenance period. stage (Table 2), (assuming that the ME of dog feed is 3.5kcal/g DM, if it exceeds 4.0 kcal/g DM, it should be adjusted according to the proportion).

2. Nutritional deficiencies

Generally, when the protein, amino acids, linolenic acid, certain minerals, VA and certain VB in the animal body are lacking, the condition of the fur will be affected. The quality of feed raw materials will also affect the biological effects of some important nutrients. The price decreases, resulting in a decrease in the color and quality of pet fur.

1. Protein deficiency

Protein deficiency will lead to abnormal fur keratinization, making the skin susceptible to damage. The hair will become thinner, faded and easily broken, the growth will be slowed or even stopped, and the epidermal fat layer will be damaged, resulting in scaly and greasy skin. The most abundant amino acid in fur protein is the sulfur-containing cystine. A lack of sulfur-containing amino acids in dog feed often leads to coat problems.

2. Fat deficiencyLack

Low-fat diet can cause the dog's coat to be dull, the skin to be dry and scaly, and fat-soluble vitamins are easily deficient, which affects growth and can increase mortality in severe cases.
