Description
Technical Field
The invention belongs to the field of feed additives, and particularly relates to a choline chloride feed additive and a preparation method thereof.
Background
The growth and development of the poultry and the livestock need certain microelements and vitamins, so that the poultry and the livestock are developed robustly and the growth and reproductive capacity of the poultry and the livestock are accelerated. Choline (2-hydroxyethyl-trimethylcholine hydroxide) is one of the vitamin B. It has strong basicity, choline chloride (C)5H14NCLO) is choline chloride, the aqueous solution being weakly acidic. The functional action of choline in metabolism and growth of livestock and poultry is mainly shown in that (1) choline is converted into betaine, methyl is provided to combine with homocysteine to form methionine, and the cost of feed is reduced; (2) as an important component of lecithin, the lecithin plays an important role in preventing the poultry shin bone rough disease and the pig limb external spread disease; (3) preventing fatty liver by promoting fat transport in the form of lecithin or by preventing abnormal accumulation of fat by increasing liver's utilization of fatty acids; (4) and is involved in nerve conduction. Choline is a precursor of the neurotransmitter acetylcholine, an important constituent of sphingomyelin. The choline chloride has obvious effects of promoting the growth and development of livestock and poultry, improving the quality of meat and eggs, preventing and resisting diseases and reducing the cost of feed, and is an indispensable vitamin feed additive.
At present, most manufacturers take bran, corncob or rice chaff and the like as carriers, and dilute choline chloride into 50% powder for use in feed production. On one hand, the produced 50% choline chloride feed additive is easy to oxidize, and the condition of moisture absorption and caking or paste formation can occur after being exposed for 30 min. Therefore, the feed additive has short storage period and easy deterioration, resulting in poor palatability and low nutritional ingredients.

A choline chloride feed additive comprises, by weight, 50-70 parts of choline chloride, 1-3 parts of chitosan and 10-15 parts of bean dreg powder.
Preferably, the feed comprises 60 parts of choline chloride, 2 parts of chitosan and 13 parts of bean dregs powder by weight.
Preferably, the chitosan is a chlorinated chitosan.
In addition, the invention also provides a preparation method of the choline chloride feed additive, which comprises the following steps:
(1) respectively weighing choline chloride, chitosan and bean dreg powder according to parts by weight;

Preferably, the vacuum drying time in step (4) is 3-5 h.
Preferably, the temperature of the vacuum drying in the step (4) is 60-70 ℃.
Compared with the prior art, the invention has the beneficial effects that:
(1) the choline chloride feed additive disclosed by the invention has good antibacterial property, is not easy to oxidize and disperse in water, does not cake within 3 months, improves the storage effect of the feed, and effectively prolongs the storage time of the choline chloride feed additive. Under acidic condition, the chitosan is easy to dissolve, and the dissolved chitosan contains amino (NH)2+) The amino groups are combined with choline chloride and the bean dreg powder, so that on one hand, the activity of bacteria in the air can be inhibited, the choline chloride feed additive is prevented from being oxidized, on the other hand, the activity of calcium ions, phosphorus ions and iron ions in the bean dreg powder can be inhibited, and the oxidation resistance is realized. Therefore, under the interaction of the chitosan, the choline chloride and the bean dreg powder, the invention effectively prolongs the storage time of the choline chloride feed additive, is not easy to deteriorate and does not influence the taste;
(2) because the bean dreg powder contains trace elements such as calcium, phosphorus, iron and the like, and the chitosan chloride is an amino polysaccharide, under the combined action of the bean dreg powder and the chitosan chloride, the absorption of animal cells to the trace elements is effectively promoted, the comprehensive and balanced nutritional ingredients of animals are ensured, the dual nutritional effects of the trace elements and amino groups are provided for the animals, the immunity and the anti-stress capability of the animals are effectively improved, diseases are prevented, the constipation of the animals is prevented, and the reproductive performance of the animals is further improved;
(3) the invention has good taste, no toxic or side effect, no chemical antioxidant and no toxic or side effect, completely abandons the harm of the chemical antioxidant to animals, can be added into the feed of the animals, and is suitable for long-term use;
(4) the preparation method is simple, the raw materials are few, and the cost is low.
