Embodiment 1

[0054] Mix Boluohui and ethanol according to the ratio of material to liquid: 15g: 175mL, and extract at 55°C for 27h to obtain the extract, according to 1mL: 3×10 6 Mix the extract and Lactobacillus in a specific ratio, and ferment at 36.5°C for 18 hours, and the Debo falls back to the extract.

[0055] Mix Epimedium and acid solution according to the ratio of material to liquid: 5g: 18mL, hydrolyze at 70°C for 27 hours, add chitosan solution to the hydrolyzed solution obtained after hydrolysis at a volume ratio of 4:10, and then add chitosan solution at 95 The reaction was carried out at ℃ for 5.5 hours, and the supernatant was collected to obtain the epimedium extract.

[0056] According to the ratio of material to liquid: 0.75g: 5.5g: 35mL, mix the rare earth metal salt containing lanthanum and cerium, glucosamine and water, react at 60°C for 12h, collect the precipitate, and obtain the rare earth glucosamine chelate salt.

Embodiment 2

[0061] The difference between this embodiment and Example 1 is: the plant extract of 0.8 parts by weight is mixed with the defatted rice bran of 72.2 parts by weight, and then with the coconut oil powder of 15 parts by weight, the rare earth chitosamine chelate salt of 6 parts by weight And 6 parts by weight of zinc lactate are mixed to obtain a feed additive for improving the immunity of fattening pigs and alleviating transportation stress.

Embodiment 3

[0063] The difference between this embodiment and Example 1 is: the plant extract of 1.2 parts by weight is mixed with the defatted rice bran of 60.8 parts by weight, and then with the coconut oil powder of 20 parts by weight, the rare earth chitosamine chelate salt of 9 parts by weight And 9 parts by weight of zinc lactate are mixed to obtain a feed additive for improving the immunity of fattening pigs and alleviating transportation stress.

Abstract

The invention relates to a feed additive capable of enhancing immunity and relieving transport stress of fattening pigs as well as a preparation method and an application of the feed additive and belongs to the feed field. The feed additive is prepared from, in parts by weight, 0.4-2 parts of plant extracts, 10-30 parts of coconut oil, 3-15 parts of rare earth-chitosamine chelate salt, 3-15 partsof zinc lactate and 38-83.6 parts of a carrier. The plant extracts comprise a macleaya cordata extract and a herba epimedii extract. The feed additive is safe, harmless, small in dosage, low in cost and stable in effect. The preparation method of the feed additive comprises the step of mixing the components of the feeding additive. The preparation method is simple and good in condition controllability. The feed additive can effectively enhance the immunity and disease resistance of the fattening pigs, improve intestinal health of the fattening pigs and relieve transport stress reactions afterbeing applied to preparation of fattening pig feed to feed the fattening pigs.

Description

technical field [0001] The invention relates to the field of feed, and in particular to a feed additive for improving the immunity of fattening pigs and alleviating transportation stress, as well as its preparation method and application. Background technique [0002] Fattening is the last production link of pig breeding, and it is also the ultimate goal of developing pig production. The task of the fattening center is to carry out scientific breeding according to the growth law of pigs, so as to maximize the production of pigs, thereby improving the economic benefits of pig production. However, under the modern intensive breeding mode, the occurrence of diseases has become the biggest reason for breeding failure. Antibiotics are commonly used in actual production to deal with infectious diseases, but antibiotics cause certain harm to human health and the environment. Therefore, it is necessary to improve the immune function of fattening pigs through immunomodulators, enha...
