Problems solved by technology

However, whether the effect of different starch sources in the diet on the intestinal health of weaned piglets is caused by the difference in the ratio of amylose to amylopectin in the starch has not been reported, and further research is needed

Embodiment Construction

[0008] The present invention will be described in detail below in conjunction with specific embodiments.

[0009] The purpose of the present invention is to rationally match the feed starch source to improve the production performance of piglets, improve the intestinal microflora, improve the absorption and transfer of intestinal nutrients, reduce weaning stress and diarrhea, and improve the intestinal health of piglets.

[0010] In order to achieve the above object, the present invention takes weaned piglets as experimental animals, feeds different starch source combination rations, and finds out the protective effect of the starch source combination on piglet intestinal health, etc. to achieve the purpose of the present invention.

[0011] The present invention adopts a single factor test design, selects 28 weaned DLY pigs with similar farrowing period, similar parity, and 6.5-7kg health in the same environment, weaned at the age of 21 days, and is randomly divided into 4 tre...

Abstract

The invention discloses a diet starch source combination capable of improving health of intestinal tracts of piglets. The ratio of amylose to amylopectin is 0.48, so that the concentration of total short chain fatty acids, particularly the concentration and the molar ratio of butyrate, of contents in cecum and colon of a piglet can be increased, and accordingly maintaining of completeness and functions of enterocyte of hindgut of the piglet is facilitated. After the piglet is fed by feed containing the amylose and the amylopectin with the ratio of 0.48 for a long time, the gastro-intestinal morphology and the intestinal enzyme activity of the piglet can be improved, the height of intestinal villus is increased, the depth of a crypt is increased, accordingly, growth and development of the small intestine of the piglet can be promoted, and the gastro-intestinal morphology structure is improved. As a starch source with the ratio of the amylose to amylopectin to be 0.48 is used as a daily feed energy source, health of the intestinal tracts of the piglet is possibly facilitated, and development of later-period production performance of the piglet is also facilitated.

Description

technical field [0001] The invention relates to a dietary starch source combination capable of improving intestinal health of piglets. Background technique [0002] The research on the relationship between nutrition and intestinal health has always been one of the key contents of traditional nutrition and modern clinical nutrition research. For piglets, the structure of the gastrointestinal tract and the development of immune function are not perfect, and weaned piglets are faced with stress from many factors, which may lead to the disorder of intestinal function in weaned piglets, especially the change of intestinal morphology , the change of intestinal microflora and the obstruction of intestinal development, thus affecting the intestinal health of weaned piglets, resulting in reduced production performance, increased diarrhea and mortality. Therefore, in today's post-antibiotic era, how to regulate the intestinal health of weaned piglets through nutrition to ensure the p...
