Most of the existing feed additives contain hormones. Although such additives can quickly promote the growth of livestock and poultry, long-term use has serious side effects, and drug residues will be produced in meat, eggs and the environment, which will affect human health.
In addition, conventional feed additives can only promote the growth rate of livestock and poultry. Once the livestock and poultry are infected, antibiotics and other drugs must be used for treatment. In the long run, the abuse of antibiotics will easily lead to drug resistance in livestock and poultry, and there will be drug residues in the livestock and poultry. , will eventually affect human health through the food chain
Ordinary livestock and poultry feed additives, especially chicken feed additives, are mostly aimed at broiler or laying hens, while feed additives dedicated to broiler chicks are rare. Broiler chicks are weak and sickly, susceptible to infectious diseases, and the survival rate Not high, the use of ordinary chicken feed or ordinary additives often cannot meet the growth needs of chickens at this stage

Embodiment 1
[0015] Example 1 : A special feed additive for broiler chicks, which is made by pulverizing the following raw materials in parts by weight: 4 parts of chicken vines, 9 parts of rice buds, 4 parts of cumin, 3 parts of salvia miltiorrhiza, 6 parts of poria cocos, 5 parts of rhizome, gallnut 3 parts, 7 parts of yam, 13 parts of pine needles, 6 parts of medical stone, 25 parts of carrier. The preparation method is as follows: weighing and weighing chicken vine, rice buds, fennel, salvia miltiorrhiza, poria cocos, guanzhong, gallnut, yam, pine needles, medical stone and carrier according to parts by weight, mixing and pulverizing to 40-60 mesh, stirring evenly to obtain The special feed additive for broiler chicks.
Embodiment 2
[0016] Example 2 : A special feed additive for broiler chicks, which is made by pulverizing the following raw materials in parts by weight: 5 parts of fennel, 11 parts of rice buds, 3 parts of cumin, 4 parts of salvia miltiorrhiza, 6 parts of poria cocos, 6 parts of peony, gallnut 4 parts, 6 parts of yam, 15 parts of pine needles, 4 parts of medical stone, 22 parts of carrier. The preparation method is as follows: weighing and weighing chicken vine, rice buds, fennel, salvia miltiorrhiza, poria cocos, guanzhong, gallnut, yam, pine needles, medical stone and carrier according to parts by weight, mixing and pulverizing to 40-60 mesh, stirring evenly to obtain The special feed additive for broiler chicks.
Embodiment 3
[0017] Embodiment 3: animal test
[0018] Select 2000 broiler chicks born in the same batch and with basically the same growth status, divide them into 5 groups, 400 birds in each group, and start the feeding test from the second week of birth, wherein group 1 is the blank group, and the feed It is the corn glutenpowder that adds 1.2wt% in the common chick compound feed; Group 2,3 is the experimental group, and the feed that it is fed is the meat use of embodiment 1,2 that adds 1.2wt% in the common chick compound feed. Special feed additive for chicks; Groups 4 and 5 are comparative experimental groups, and the feed they feed is the feed additive of comparative test examples 1 and 2 that add 1.2wt% in common chick compound feed, and the test lasts for 5 weeks. The growth status, daily average weight gain and survival rate at the end of the test, etc., the specific results are shown in Table 1 below:

Abstract
The invention relates to a special feed additive for a broiler chick. The special feed additive is prepared by crushing the following raw materials by weight: 3 to 5 parts of Chinese febervine herb, 8 to 12 parts of rice-grain sprout, 3 to 5 parts of common fennel fruit, 2 to 4 parts of red sage root, 5 to 7 parts of Poria cocos, 4 to 7 parts of cyrtomiumrhizome, 2 to 4 parts of Chinese gall, 6 to 8 parts of Chinese yam, 12 to 15 parts of pine needle, 4 to 7 parts of Chinese medical stone and 20 to 30 parts of a carrier. With the special feed additive for the broiler chick, immunity and disease resistance of the broiler chick can be effectively improved, and the survival rate of the broiler chick is increased by 8 to 11% compared with that of a blank control group; the growth speed of the broiler chick is increased, an increase by 10 to 15% compared with the growth speed of the control group; anti-stress capability of the broiler chick is greatly improved, and the broiler chick has enhanced adaptability to temperature and can rapidly adapt to a free-ranging environment in the case of free-ranging; muscles of a chicken grown from the broiler chick fed by the feed additive have better flavor compared with muscles of a chicken grown from the control group.
Description
technical field [0001] The invention belongs to the field of feed, and relates to a feed additive for chickens, in particular to a special feed additive for broiler chicks. Background technique [0002] my country's poultry industry has a long history. Since the reform and opening up 30 years ago, it has developed very rapidly. It has developed from a family-style sporadic free-range farming to an intensive, specialized, and modern industry, and has become a major economic pillar of my country's rural areas and animal husbandry. . Chicks refer to chickens from hatching to 7 weeks of age. The health of chicks is the basis for ensuring the performance of chickens and the economic benefits of raising chickens. The physiological characteristics of chicks are very different from those of adult chickens. The young chicks just out of the shell are not perfect due to various physiological functions, low temperature regulation ability, low resistance, weak digestive function, small g...
