Technical Field

The invention belongs to the technical field of feed additives, and particularly relates to a compound acidifier for poultry, and a preparation method and application thereof.

Background

The genetic development trend in the tissues and organs of the broiler chickens is the biggest muscle and skeleton, and the changes of digestive organs and an immune system are small, so that the response of modern broiler chickens to immune response is reduced, and the inflammatory response is increased. Meanwhile, the broiler chicken has weak protein digestion capability due to relative insufficient gastric acid secretion, insufficient protein digestive enzyme activity and short digestive tract. The protein is not completely digested, so that a nutrient source is provided for the later intestinal tract, and the undigested and absorbed nutrients are fermented and utilized by microorganisms, so that harmful substances in the intestinal tract are increased, and the intestinal tract structure is damaged. In the breeding production process, pathogenic microorganisms in feed, padding and drinking water enter the body through propagation ways of ingestion, drinking, respiration and the like of animals, and the digestion and absorption problems caused by intestinal injury, enzyme activity reduction and the like and the immunity reduction and the like all cause the intestinal health problems of poultry, so that the problems of insufficient development of growth potential, material excretion, outbreak of diseases, high mortality and the like are finally caused. In practice, the problem of incomplete protein digestion is generally solved by optimizing the protein material, but this method is very limited due to the lack of good quality material and cost. In addition, poultry productivity and disease resistance can be improved by the addition of growth promoters and antibiotics, but this approach has been associated with increasingly severe drug resistance, drug residues, and environmental problems.

Acidifying agent by supplying H⁺The pH value of the gastrointestinal tract is reduced, the protein denaturation can be promoted, and the activity of digestive enzyme is improved; the acidifier can regulate the balance of microbial flora in digestive tract, promote the development of immune system, and directly participate in vivo energy metabolism to improve anti-stress ability and promote the growth of animals by changing the growth environment of bacteria, reducing nutrients required by bacteria and in molecular form; the acidifier is a high-efficiency, pollution-free and residue-free feed additive, and is regarded as one of the products capable of effectively replacing antibiotics. Due to the existence of digestive physiology of different bred livestockThe difference is large, so the dosage and the type of the required acid also have difference, and the existing general acidifier cannot be suitable for different raised livestock; in addition, the existing acidifier has no sterilization and corrosion prevention effects and cannot meet the high-quality requirement of the feed.

Cinnamaldehyde is an aldehyde organic compound, is a yellow viscous liquid, exists in plants such as cinnamon in a large amount, has strong fragrance of cinnamon oil, is insoluble in water and glycerol, and is easily soluble in alcohol, ether and petroleum ether. It can be used for sterilization, disinfection and preservation, and has remarkable effect on fungi. However, cinnamaldehyde can volatilize with water vapor, is unstable in a strongly acidic or strongly basic medium, is liable to cause discoloration, and is liable to oxidize in the air. Currently, there are few studies on the compounding of acidulant raw material with cinnamaldehyde as a plant extract.
