Classification Of Feed Additives
1. Bile acids
Longchang bile acid is the main active component of bile. In the hepatointestinal circulation, it combines with fatty acid, emulsifies fat, and forms fat-soluble complex with fatty acid, so that fatty acid can be absorbed through membrane and digested and absorbed. All biochemical reactions, especially enzymatic reactions, are carried out in aqueous solution, so fat can enter the fatty acid enzymatic hydrolysis process only when it is emulsified and forms a fatty acid-emulsifier complex. Because the hepatointestinal circulation is not a completely closed cycle, the insufficient secretion of endogenous emulsifiers is the biggest factor affecting the digestion and absorption of fat. Feed grade bile acid is a high performance fat emulsifier. It can improve the activity of endogenous emulsifier, make up for the deficiency of endogenous emulsifier secretion, and release potential energy of feed. It can promote the digestion and absorption of fat, protect liver and gallbladder, improve the health of livestock and poultry, and improve the utilization rate of feed.
2. Acidizing agent
Including citric acid, fumaric acid, lactic acid, acetic acid, hydrochloric acid, phosphoric acid and complex acidizing agent, adding proper amount of acidification in pig diets can significantly increase pig daily gain and reduce feeding costs.
3, calcium formate
As a feed additive, calcium formate is especially suitable for weaning piglets. It can affect the proliferation of intestinal microorganisms, activate pepsinogen, improve the energy utilization of natural metabolites, improve feed conversion rate, prevent diarrhea and dysentery, and improve the survival rate and daily gain rate of piglets. At the same time, feed-grade calcium formate also has anti-mildew and fresh-keeping effect. Adding calcium formate to feed can release trace formic acid in animal body, which can reduce the PH value of gastrointestinal tract and has buffering effect. It is conducive to the stability of PH value in gastrointestinal tract, thus inhibiting the reproduction of harmful bacteria and promoting the growth of beneficial microorganisms, such as Lactobacillus, so as to cover intestinal mucosa without the invasion of toxins. In order to control and prevent bacterial-related diarrhea, dysentery and other phenomena, the dosage is generally 1-1.5%. Calcium formate as acidifier, compared with citric acid, in the feed production process will not be deliquescent, fluidity is good, PH value is neutral, will not cause equipment corrosion, directly added to the feed can prevent the destruction of vitamins and amino acids and other nutrients, is an ideal feed acidifier.
4, sodium diacetate
Sodium diacetate is a kind of feed antifungal preservative, acidic agent and improver with stable properties. Appearance is white powder, with acetic acid odor, easy to absorb moisture, very soluble in water. Naturally, sodium diacetate releases acetic acid slowly. Acetic acid can penetrate into the cell wall of fungal tissue effectively, interfere with the interaction of enzymes between cells, and denaturate the protein in cells, thus playing an anti-bacterial and anti-mildew role. The use of sodium diacetate not only keeps the bactericidal performance of acetic acid, but also does not cause the poor palatability of feed due to too much acidity. Therefore, SDA can prevent the storage of food and beverages from mildewing and spoilage, thus having the effect of anti-mildew and fresh-keeping.
5, promoting growth
It includes the four main components, namely, ethyl alcohol, fast growing pigs, fast growing essence, blood products, liver dregs, livestock and poultry, fat pig and so on.
6. Trace elements
Including copper, iron, zinc, cobalt, manganese, iodine, selenium, calcium, phosphorus and so on, it can regulate metabolism, promote growth and development, enhance disease resistance and improve feed utilization. Adding daily gain of post growing pigs can generally increase 10%-20% and reduce feed cost by 8%-10%.
They include vitamin A, D2, E, K3, B1, D3, B2, B6, C, and vitamins, choline, pig premix additives, vitamine, taitar -80, French fertilizer, health hormone, strong hormone, etc., which can be scientifically selected according to different pig breeds and different growth stages.
8, amino acids
Including 18 kinds of amino acids such as lysine, methionine and glutamic acid, as well as raw treasure, poultry and livestock treasure, feed yeast, feather powder, earthworm powder, feeding music and so on, the most used additives are lysine and methionine, adding 0.2% lysine to the diet to feed pigs, daily gain can be increased by about 10%.
Gold toxin, salt mycin, tetracycline, Bacillin, lincomycin, Kangtai feed additive and pig Bao, Bao Sheng Su, etc.
10, insect repellent health care
Including Anbaoqiujing, Keqiufang, Hebao-34 and so on.
11. Mould proof.
Because rice bran, fish meal and other concentrate feed have high oil content, easy to oxidize and deteriorate for a long time, adding ethoxyquinoline can prevent feed oxidation, adding propionic acid, sodium propionate and so on can prevent feed mildew. The addition of cinnamon powder not only has a strong bactericidal effect, but also has the effect of fragrance, food attraction, drug health care and growth promotion lamp.
12. Chinese herbal medicine
Including garlic, mugwort pine needle powder, mirabilite, Codonopsis leaves, Maifanshi, wild hawthorn, orange peel powder, Huwujia, Atractylodes macrocephala, Leonurus heterophylla, etc.
13, buffering feed
Including sodium bicarbonate, calcium carbonate, magnesium oxide, calcium phosphate and so on.
Including sodium glutamate, sodium chloride, citric acid, lactose, maltose, hay and so on.
Including raw milk record, auxiliaries, fattening agents, etc.
