The common health feed for ducks and ducks includes growth promoters (such as antibiotics, synthetic antibacterial drugs and enzyme preparations), and insect repellent health care agents (such as anticoccidial drugs). Although it is not an inherent nutrient in feed, it has no nutritional value, but it has antibacterial, anti-disease, maintain body health, improve palatability, promote growth, and increase feed remuneration.
Chinese herbal medicine feed additives
As a feed additive, Chinese herbal medicine has small toxic and side effects and is not easy to remain in the product. It has a variety of nutrients and biological active substances, and it also has the dual role of nutrition and disease prevention. Its natural, multi-functional and nutritive characteristics can play a role in enhancing immunity, hormone-like, vitamin-like, anti-stress, anti-microbial, etc., and has broad application prospects.
Feed enzyme additives
Enzymes are proteins synthesized by animals and plant organisms that have special functions. They are also catalysts for the digestion of proteins, fats, and carbohydrates, and they are involved in the biochemical reactions of various metabolic processes in the body. Adding enzyme preparations to the duck feed can increase the digestibility of nutrients.
Common feed enzyme additives are single enzyme preparations and complex enzyme preparations. Single enzyme preparations, such as alpha-amylase, beta-glucanase, lipase, cellulase, and phytase; complex enzyme preparations consist of one or more single enzyme preparations plus other single enzymes The preparations are mixed or obtained by fermentation of one or more microorganisms. The complex enzyme preparation can simultaneously degrade a plurality of substrates (multiple anti-nutritional factors and various nutrients) that need to be degraded in the feed, and can maximize the nutritional value of the feed. Domestic and foreign feed enzyme products are mainly compound enzyme preparations, such as feed complex enzymes based on proteases and amylase.
Enzyme preparations are mainly used to supplement the deficiency of animal endogenous enzymes; glucanase-based feed complex enzyme preparations are mainly used for feeds based on barley and oats as the main raw materials; mainly based on cellulase and pectinase. The main role of feed complex enzyme is to destroy the plant cell wall, release the nutrients in the cell, easy to be digestive enzymes, promote digestion and absorption, and eliminate the anti-nutritional factors in the feed, promote the digestion and absorption of animals; use cellulase The feed complex enzyme mainly composed of protease, amylase, glucoamylase, glucanase, and pectinase can synthesize the effects of the above enzymes and have a stronger assisting effect on digestion. The amount of enzyme preparation depends on the size of the enzyme activity. Different enzyme preparations have different activities, and the effect of supplementing the enzyme preparation is related to the age of the animal.
Since most of the major mineral nutrients lacking in the modern aquaculture and feed industries are phosphorus, 70% of the phosphorus in the seeds of crops such as soybean meal, cottonseed meal, rapeseed meal, corn and wheat bran is phytate phosphorus and cannot be used by ducks. , excreted in the body with the faeces. This not only results in the waste of resources and pollution of the environment, but also the fact that phytic acid is present in the digestive tract of animals as an anti-nutritional factor, which can affect the absorption of calcium, magnesium, potassium, iron and other cations and proteins, starch, fat, and vitamins. Phytase can hydrolyze phytic acid (inositol hexaphosphate) to release the available phosphorus which can be absorbed. This not only eliminates the anti-nutritional factors, increases the available phosphorus, but also increases the absorption and utilization of other nutrients that are antagonized. .
Microecological agents
Microecological preparations, also known as beneficial bacteria preparations or probiotics, are live bacterial preparations that are specially used for animal nutrition and health care by artificially screening and cultivating beneficial microorganisms in animals, and then undergoing modern bioengineering factory production. It contains more than a dozen or even dozens of livestock and poultry gastrointestinal beneficial bacteria, such as Gatobacillus, effective microorganisms (EM), probiotics, etc., but also a single bacterial preparation, such as lactic acid bacteria preparations. However, in addition to some special needs in the aquaculture industry, multiple combinations of bacteria are used. In addition to feeding with feed additives and drinking water, it can also be used to ferment straw and duck dung to make biofermented feeds, which can not only increase the digestion and absorption rate of roughage, but also turn waste into treasure and reduce pollution. After the microecological preparation enters the digestive tract, it first establishes and restores the dominant flora and microecological balance in the digestive tract, and produces some digestive bacteria, antibiotic substances, and biological active substances, so as to increase the digestion and absorption rate of the feed and reduce the feed cost; E. coli and other harmful bacteria infection, enhance the body's resistance to disease and immunity, can use less or no antibacterial drugs; significantly improve the feeding environment, so that the ammonia in the duck house, hydrogen sulfide and other odor gases by more than 70%.
