Abstract

The application discloses a pet feed additive for enhancing gastrointestinal motility. The double-layer embedding structure is adopted, wherein the outer layer is a pH response type compound formed by chitosan and sodium alginate, the effects of stomach protection and intestinal targeting slow release are achieved, and the inner layer core is a compound of resveratrol and inulin and selenium-enriched yeast prepared through bioconversion. The composition has the synergistic effect of regulating intestinal nerves and resisting inflammation by using resveratrol, promoting proliferation of beneficial bacteria by using inulin as a prebiotic, and enhancing the antioxidant capacity of intestinal mucosa by using organic selenium, thereby comprehensively and safely promoting gastrointestinal peristalsis. Experiments show that the additive can obviously improve defecation condition, shorten gastrointestinal transmission time, optimize intestinal flora and reduce inflammation, and is suitable for being added into pet food needing to improve gastrointestinal motility.

Description

Pet feed additive for enhancing gastrointestinal motility Technical Field The application relates to the technical field of pet foods, in particular to a pet feed additive for enhancing gastrointestinal peristalsis. Background With the development of social and economic level and the change of life style of people, the position of pets in families is increasingly promoted, and the pets become important emotion accompanies with family members. The health and welfare of pets are widely regarded, and the gastrointestinal health is taken as a basic stone for the overall health of pets, and is directly related to the nutrition absorption efficiency, the immune system function, the mental state and the life quality. However, in pet feeding practice, gastrointestinal dysfunction is increasingly prominent due to the effects of single dietary structure, reduced metabolism caused by aging, environmental stress, genetic factors or potential diseases, etc., where retarded gastrointestinal motility is particularly common. The reduced peristaltic function of the gastrointestinal tract may result in an extended residence time of food in the digestive tract, which may lead to a range of clinical symptoms including, but not limited to, anorexia, abdominal distention, constipation, laborious bowel movements, dry stool, or morphological abnormalities. If effective intervention is not obtained for a long time, the disease can develop into chronic digestive system diseases, the absorption and utilization of nutrient substances can be influenced, the immunity of organisms is weakened, even other organ functions are involved, and the health life and the life quality of pets are seriously influenced. Currently, the means for regulating the gastrointestinal peristalsis function of pets mainly comprise the following categories: The probiotics have low survival rate in the processes of feed processing, high-temperature granulation, long-term storage and gastric acid passing environment, and have insufficient efficacy stability, and the different strains have specificity in action and limited application range. Most gastrointestinal motility promoting medicines are chemical synthetic medicines, and although the gastrointestinal motility promoting medicines have certain effects, the gastrointestinal motility promoting medicines can bring side effects after long-term use, have the risk of drug resistance and are not suitable for long-term use as feed additives. The prior art still has obvious limitations in terms of safety, stability, action durability and applicability. Therefore, there is a need to develop a novel feed additive which can safely, stably and efficiently enhance gastrointestinal peristalsis function of pets, has multi-target synergistic effect, and is easy to add and store in feed. Disclosure of Invention Aiming at the problems of insufficient safety and poor stability in the prior art, the application provides a pet feed additive for enhancing gastrointestinal peristalsis, which is formed by a double-layer embedding structure: the outer layer is chitosan sodium alginate complex, the inner layer is the mixture of resveratrol complex and selenium-enriched yeast, the multi-target synergistic effect is realized, and the gastrointestinal motility of the pet is obviously enhanced.
