Embodiment 1
[0028] The antibiotic-free feed for the fattening pig stage includes the following components by weight:
[0030] The concrete steps of above-mentioned feed preparation are as follows (wherein said main material is basic feed component, and described auxiliary material is core added component):
[0031] 1.1. Receiving: check the quality of raw materials after receiving them;
[0032] 1.2. Cleaning: ...
Embodiment 2
[0041] 1. Test material:
[0042] 1.1 100 PIC fattening pigs were provided by Chenzhou Xinxiangnong Ecological Technology Co., Ltd.
[0043] 1.2 Full-price compound feed A: See Table 1 for the feed formula. Enramycin (4 ppm) was included in the core supplement.
[0044]1.3 Full-price compound feed B: full-price compound feed for non-antibiotic pigs, the basic nutritional components are the same as the full-price compound feed A, and its core components do not contain any antibiotics, adding organic mineral premix: 0.1-0.15% , Plant essential oil: 0.004-0.01%, yeast cell wall: 0.15-0.2%, and use compound organic acidifier to replace part of corn in equal amount. The formula is shown in Table 1.

Abstract
The invention discloses an antibiotic-free feed for fattening-stage pigs. The antibiotic-free feed for the fattening-stage pigs comprises the following components in parts by weight: 40-50 parts of corns, 20-25 parts of barley, 17-20 parts of bean meal, 8-12 parts of whole rice bran, 6-8 parts of an organic compound acidifying agent, 2-5 parts of imported corn DDGS, 0.3-0.4 part of table salt, 1-1.5 parts of stone powder, 0.3-0.5 part of calcium hydrogen phosphate, 0.3-0.5 part of amino acid, 0.05-0.1 part of choline chloride, 0.03-0.1 part of a compound micro-ecological preparation, 0.02-0.05 part of an antioxidant, 0.03-0.04 part of vitamin premix, 0.1-0.15 part of organic mineral premix, 0.002-0.005 part of a compound enzyme preparation, 0.02-0.05 part of high-temperature-resistant phytase, 0.004-0.01 part of plant essence oil, 0.15-0.2 part of yeast cell walls, 0.01-0.03 part of an antioxidant, 0.02-0.05 part of an anti-mildew agent and 0.02-0.05 part of zeolite powder. The invention solves the problems of drug residues, drug resistance and environmental pollution caused by addition of the antibiotics in the feed. Moreover, the acidifying agent, the organic trace elements, the yeast cell walls and the plant essence oil are added into the feed, so that the feed has the effects of improving pig immunity and reducing disease risks of animals compared with antibiotic-containing feeds; and the feed is capable of improving production performance and meat qualities of the pigs.
Description
technical field [0001] The invention belongs to the technical field of animal nutrition, and in particular relates to an antibiotic-free feed for fattening pigs and a preparation method thereof. The feed is used for fattening pigs with a body weight of 60 kg to slaughter. Background technique [0002] Since the 1950s, antibiotics have been approved for use in animal feed. Up to now, dozens of antibiotics have been widely used in the feed industry. Because antibiotics have good antibacterial and growth-promoting effects, they have always occupied a pivotal position in the development of the feed industry. Because antibiotics can make bacteria resistant, the dose of their effect is increasing with the increase of the number of years of use, which in turn leads to the gradual increase of bacterial resistance, forming a vicious circle; at the same time, the high dose of antibiotics The addition also led to the increase of antibiotic residues in the environment and in animal pro...
