Feed composition, composite premix and functional feed for improving intestinal flora structure of weaned pig

Abstract

The invention provides a feed composition for improving an intestinal flora structure of a weaned pig. The feed composition comprises the following components in parts by weight: 0.05-0.5 part of probiotics, 0.1-0.5 part of an immunoreactive substance, 0.01-0.1 part of a plant extract and 0.1-3 parts of an acidifying agent. The invention further provides a composite premix and functional feed for improving an intestinal flora structure of a weaned pig. The feed composition and the composite premix and functional feed obtained thereby provided by the invention have multiple effects of improving the food intake of piglets, reducing the diarrhea rate, improving the intestinal flora balance, improving the immunity and the like, are free of any antibiotic, conform to the ideal amino acid pattern, meet the requirements in the aspects of electrolyte balance and mineral balance, and comprehensively meet the nutrition and health requirements of weaned pigs. Meanwhile, the cost performance is taken into account, and the benefits of pig farms can be greatly improved when the feed composition, the composite premix and the functional feed are used for piglet breeding.

Description

technical field [0001] The invention relates to the field of feed and feed additives, in particular to a feed composition, compound premix and functional feed for improving the intestinal flora structure of weaned piglets. Background technique [0002] With the intensive and large-scale development of pig farming, the incidence of diarrhea in suckling piglets is getting higher and higher, especially the yellow and white scour of piglets, which has a high morbidity and mortality rate and has caused great economic losses to the breeding industry. Antibiotics have always been the most important way to prevent and treat yellow and white scour of piglets. To a certain extent, antibiotics inhibit the growth of pathogenic bacteria in the intestinal tract, but at the same time, they also inhibit the function of normal flora. Long-term use can easily cause digestive tract diseases. In recent years, a series of problems that seriously threaten human health due to the abuse of antibiot...
