Problems solved by technology

However, the long-term use of antibiotics in large quantities, resulting in drug residues and bacterial drug resistance, has become an urgent problem to be solved under the current "ecological farming" trend. Therefore, it has become an inevitable trend to gradually replace the use of feed antibiotics. Probiotics, acidification Antibiotics have been studied successively to replace antibiotics. However, most of the alternatives to antibiotics are only in the research stage. At present, there is no pig ration product that does not add antibiotics at all. Basically, a pig diet that can completely eliminate antibiotics is of great significance for the realization of ecological breeding

Abstract

The invention discloses application of algal polysaccharides for replacing antibiotics in daily ration of weaned pigs, and belongs to the technical field of pig cultivation. The application of the algal polysaccharides for replacing the antibiotics in the daily ration of the weaned pigs is characterized in that the adding amount of the algal polysaccharides in the daily ration of the weaned pigs is 400 mg / kg, and the content of polysaccharide in the algal polysaccharides is 30%. According to the application of the algal polysaccharides for replacing the antibiotics in the daily ration of the weaned pigs, on the basis of the conditions that the growth performance of the piglets is not influenced, even daily gain of the piglets can be improved remarkably, and piglet diarrhea frequency and feed-gain ratio are reduced remarkably, the effects that stress reaction of the piglets caused by weaning can be alleviated, intestinal structural development and gut immunity of the weaned pigs are promoted and the like are realized; the effect of completely replacing the antibiotics can be realized.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to the application of seaweed polysaccharide instead of antibiotics in the ration of weaned piglets. Background technique [0002] Early weaning piglets are prone to "early weaning syndrome" due to changes in environmental and nutritional factors, with symptoms such as low feed utilization, digestive disorders, and diarrhea, and the growth of piglets is severely hindered. Antibiotics can promote animal growth, reduce diarrhea and improve disease resistance, and are widely used in the current farming industry. However, the long-term use of antibiotics in large quantities, resulting in drug residues and bacterial resistance, has become an urgent problem to be solved under the current "ecological farming" trend. Therefore, it has become an inevitable trend to gradually replace the use of antibiotics in feed. Probiotics, acidification Antibiotics have been studied succ...
