Dog food for intestinal tract care and preparation method thereof
Technical Field
The invention belongs to the field of pet feed preparation, and particularly relates to a dog food for intestinal tract care and a preparation method thereof.
Background
The dog food is a high-grade animal food which is specially provided for pet dogs and is between human food and traditional livestock and poultry feed. The function of the feed is mainly to provide the most basic nutrient substances required by life guarantee, growth and development and health for pet dogs. The dog food has the advantages of comprehensive nutrition, high digestibility, scientific formula, standard quality, convenience in feeding, capability of preventing certain diseases and the like. Along with the increase of the feeding amount of pet dogs, the processing quality of dog food is noticed by pet owners, and meanwhile, a new development space is brought for processing agricultural products and meat products and poultry.
Gastrointestinal diseases are one of diseases to which pet dogs are prone and one of diseases which occur most frequently in summer, and main symptoms comprise: inappetence, oral malodor, vomiting, diarrhea, food intolerance, digestive system disorders, etc., wherein the gastrointestinal tract diseases which are more common clinically are gastroenteritis and colitis.
Gastroenteritis is characterized by vomiting and diarrhea, often with sudden onset, rapid acute onset, short duration, marked clinical symptoms, and a common cause of sudden changes in food in the near term, such as: overeating or eating spoiled food, foreign bodies, or irritant drugs, unclean drinking water, and the like, and other causes include bacterial viral infection, intestinal parasitic disease infection, stress state of treatment, diseases of other organs such as xerosis and kidney disease, and the like.
The most common symptom of colitis is intermittent or persistent diarrhea, which may be accompanied by weight loss if the disease is chronic. Common causes of disease include: overeating or eating deteriorated food, foreign bodies, or irritant drugs and unclean drinking water, bacterial and viral infection, intestinal parasitic disease infection, reaction to certain drugs, food allergy or intolerance, etc.
For acute gastrointestinal diseases, drug therapy is usually the fastest and most effective treatment, but is critical for the dietary management of chronic gastrointestinal diseases. The purpose of the diet is to provide food to meet the nutritional needs of the pet while helping to restore normal gastrointestinal function. However, at present, the research on the specific dog food provided for pet dogs suffering from gastrointestinal diseases is less, and most of the pet dogs are fed by self according to the recommendation of doctors, and the effect of the method is not good. Therefore, it is desirable to provide a dog food for enteral care for feeding sick pet dogs.

Example 4
10 adult normal bear dogs (with the weight of about 7.5 kg and meeting the requirements of animal experiment standards) are selected to be divided into two groups, and each group is divided into five dogs; wherein the treatment group was fed with the feed prepared in example 1, and the control group was fed with a commercial basal feed in a daily feeding amount of 150g feed/day for a test period of 2 months. The mental state of the panda dog is observed during the experiment, and the disease condition and symptoms are recorded.
The stomach and intestine of the panda dog is fragile, and the panda dog is easy to suffer from stomach and intestine diseases and has symptoms of inappetence, diarrhea, vomiting and the like. In the experimental process, three of the pandas fed with the commercial basal feed exhibited symptoms of vomiting and diarrhea, while none of the five pandas fed with the feed prepared in example 1 exhibited symptoms of loss of appetite, diarrhea, vomiting, and the like, and the mental state was good, and the results are shown in table 1.

In this example, the numbers of escherichia coli, lactobacillus and bifidobacterium in feces before and after the experiment of three control bear dogs with symptoms of vomiting, diarrhea and the like and the numbers of escherichia coli, lactobacillus and bifidobacterium in feces before and after the experiment of any three control bear dogs in the treatment group were further analyzed, and the results are shown in table 2. As can be seen from Table 2, the numbers of Escherichia coli, Lactobacillus and Bifidobacterium in feces before and after the experiment of the three bear dogs in the treatment group were stable, further indicating that the intestinal microbial system was stable. The control group has a higher number of lactobacilli and bifidobacteria than that of colibacillus, but the number of colibacillus is obviously increased, while the number of lactobacilli and bifidobacteria is reduced, further illustrating that the intestinal microbial flora is changed.
