Problems solved by technology

However, raw soybeans contain trypsin inhibitors, flatulence factors, soybean antigens and other anti-nutritional factors, which inhibit the growth and development of animals and have a serious impact on animal health.
However, there is no research report on adding Lactobacillus acidophilus to the basal diet to feed weaned piglets to improve the intestinal barrier function and digestive enzyme activity of early weaned piglets

Abstract

The invention relates to the technical field of preparation of pig feed, and in particular discloses formula feed capable of improving the intestinal barrier function and digestive enzyme activity of early-weaned piglets, and a feeding method of the formula feed. The formula feed is prepared from basal diet and a lactobacillus acidophilus culture, wherein the mass of the lactobacillus acidophilus culture accounts for 1-5% of the total mass of the formula feed. After the formula feed provided by the invention is used for feeding the early-weaned piglets, the average daily feed intake of the weaning stress piglets can be remarkably improved, the heights of villi in the duodenum, the jejunum and the ileum are remarkably increased, the depths of recesses of the duodenum and the ileum are obviously reduced, and the heights of villi or the depths of recesses of all intestinal tracts of small intestines are significantly improved. The contents of sucrase, lactase and maltase of the jejunum are remarkably improved. The formula feed is easy in obtaining of raw materials, simple in preparation method and convenient to use.

Description

technical field [0001] The invention relates to the technical field of pig feed preparation, in particular to a feed preparation and a feeding method for improving the intestinal barrier function and digestive enzyme activity of early-weaned piglets. Background technique [0002] Early weaned piglets begin to obtain protein from the feed after weaning due to incomplete digestive system function, which leads to a series of stress reactions in early weaned piglets, among which diarrhea is the most common phenomenon, and mild diarrhea can lead to malnutrition and Growth is stunted, and severe diarrhea can lead to dehydration, mortis and even death in piglets. According to reports, in the United States, the incidence of diarrheal disease in weaned piglets is 57%, and the resulting mortality rate reaches 10.8%, which brings great economic losses to pig production. Therefore, how to implement early weaning of piglets to improve pig production efficiency, at the same time ensure t...
