Embodiment 1

[0025] Corn 52.25%, soybean meal 4%, fish meal 1%, rice bran meal 20%, coconut meal 15%, bran 4%, stone powder 1%, calcium hydrogen phosphate 1%, salt 0.25%, premix 1%, cellulase 0.5%.

Embodiment 2

[0027] Corn 57.75%, soybean meal 8%, fish meal 1.5%, rice bran meal 15%, coconut meal 10%, bran 4%, stone powder 1%, calcium hydrogen phosphate 1%, salt 0.25%, premix 1%, cellulase 0.5%.

[0028] Among the feed materials in the above examples, the mass ratios of coconut meal, a unique raw material in tropical regions, to conventional raw materials are 15% and 10%, respectively, and the cellulase activity is ≥ 5000 IU. Each kilogram of feed includes the content of each component of the premix: iron 40-100mg, copper 5-60mg, zinc 40-110mg, manganese 3-20mg, iodine 0.12-0.25mg, selenium 0.2-0.3mg, no addition to the premix any antibiotics.

[0029] The preparation method of Hainan black pig antibiotic-free fermented feed is as follows:

[0030] Step 1: Feed materials such as corn, soybean meal, fish meal, rice bran meal, coconut meal, bran and stone powder are respectively treated with a pulverizer, and the sieve aperture of the pulverizer is 1.5-3.0mm;

[0031] Step 2: mixing ...

Abstract

The invention belongs to the technical field of animal nutrition and feed formulas, and particularly relates to antibiotics-free fermented feed for Hainan black pigs and a method for preparing the antibiotics-free fermented feed. The antibiotics-free fermented feed for the Hainan black pigs comprises, by weight, 35-73% of corn, 4-25% of bean pulp, 0.5-6% of fish meal, 4-20% of rice bran meal, 5-15% of coconut meal, 4-12% of bran, 0.5-1.6% of stone powder, 0.8-1.5% of calcium hydrogen phosphate, 0.2-0.5% of table salt, 0.1-1.0% of premixes and 0.01-0.5% of enzyme preparations. The method for preparing the antibiotics-free fermented feed for the Hainan black pigs includes smashing and treating the corn, the bean pulp, the fish meal, the rice bran meal, the coconut meal, the bran, the stone powder and the like; matching the corn, the bean pulp, the fish meal, the rice bran meal, the coconut meal, the bran, the stone powder and the like with the calcium hydrogen phosphate, the table salt, the premixes and the enzyme preparations to obtain basic fermentation substrates; adding complex microbial preparations into the basic fermentation substrates and carrying out sufficient fermentation treatment to obtain the antibiotics-free fermented feed with comprehensive and balanced nutrition. The antibiotics-free fermented feed and the method have the advantages that 4-50% of antibiotics-free fermented feed is added into conventional compound feed for black pigs at different phases, accordingly, the breeding costs of the Hainan black pig can be reduced, the feed intake and the growth speeds can be increased, the health of gastrointestinal tracts of sow and piglets can be improved, and the productivity of the Hainan black pigs can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition and feed formula, and in particular relates to an antibiotic-free fermented feed for Hainan black pigs and a preparation method thereof. Background technique [0002] Hainan black pig is a strain of Hainan pig. It is a meat-fat pig breed. It is usually released for slaughter at the age of 8-10 months. It has the characteristics of strong adaptability, resistance to rough feeding and good meat flavor, and is favored by local consumers. However, Hainan black pigs have the problem of slow growth in actual breeding, and their feeding costs are relatively high. In order to pursue high growth and high return benefits, some producers often abuse various antibiotics and other growth promoters in feed, which not only causes serious Food safety issues have also led to the slow development of the black pork industry. With the improvement of living standards, people have gradually noticed the import...
