Application of rutin as anti-diarrhea digestive enhancer in preparation of piglet feed
A piglet feed and digestion-promoting technology, which is applied in the field of livestock and poultry breeding, can solve the problems of impaired intestinal mucosa and intestinal barrier function, affecting the healthy development of the pig industry, and the growth performance of piglets with diarrhea, so as to enhance the intestinal tight connection of piglets Gene and protein expression, improvement of feed utilization efficiency, effect of improvement of feed utilization efficiency

Problems solved by technology
In the early weaning mode, the immature intestinal function of piglets is subjected to the stress from liquid milk to solid feed, which leads to the damage of intestinal mucosa and intestinal barrier function of piglets, which leads to diarrhea and decreased growth performance of piglets (growth inhibition and Feed-to-weight ratio) and other phenomena seriously affect the healthy development of the pig industry

Embodiment 1
[0022] Embodiment 1: the effect of the application of rutin in the feed of weaned piglets
[0023] In order to verify the anti-diarrhea and growth-promoting effect of rutin on piglets, 14 weaned piglets from Dudu and Sanyuan were randomly divided into 2 groups, with 7 pairs of pigs in each group, and each pig was reared in a single pen as a repetition. Feed the basal diet (control group, CON) and the basal diet supplemented with 500 mg / kg rutin (rutin group, RUN) for 14 days. During the feeding period, the piglets' weight, feed intake, and diarrhea were recorded, and the average daily gain, average daily feed intake, feed-to-weight ratio, and diarrhea rate were calculated. After the feeding experiment, the animals were slaughtered and samples were taken to measure blood hormone levels and intestinal barrier-related indicators, the expression levels of intestinal mucosal tight junction genes and proteins, and the number of aerobic bacteria in mesenteric lymph nodes. The specifi...

The invention discloses application of rutin as an anti-diarrhea digestive enhancer in preparation of a piglet feed. The invention finds for the first time that by adding 300-1,000 mg / kg of rutin into the piglet feed, expression of close connection genes and proteins of the intestinal tracts of weaned piglets can be effectively enhanced, bacterial displacement is inhibited, the intestinal barrier function is improved, and the diarrhea rate is reduced. The rutin disclosed by the invention has the advantages of greenness, environment-friendliness, wide source, low cost and the like, and is a safe and efficient green feed anti-diarrhea growth promoting agent.
Description
technical field [0001] The invention relates to the field of livestock and poultry breeding, in particular to the application of rutin as an anti-diarrhea digestive promoting agent in preparing feed for piglets. Background technique [0002] my country is a big pork consuming country, and it is also a big pig breeding country, in which pig feed plays an important role in pig breeding, that is, there is a saying that "pig food is safe for the world". Intestinal health of piglets has always been the focus of research in the current intensive farming model, especially the early weaning (usually 14-28 days after birth) that is currently implemented to give full play to the reproductive performance of sows. In the early weaning mode, the immature intestinal function of piglets is subjected to the stress from liquid milk to solid feed, which leads to the damage of intestinal mucosa and intestinal barrier function of piglets, which leads to diarrhea and decreased growth performance...
