Embodiment 1

[0038] The preparation method of the high-fiber feed component A fermented by the bacterial preparation is:

[0039] 1) Grinding the high-fiber feed ingredient A to a diameter or length of 0.5-10 mesh to obtain a high-fiber feed ingredient A premix.

[0040] 2) Add 8 to 10 times the amount of sterile water and 0.2 to 0.5 times the amount of glycerin, 0.02 to 0.05 times the amount of bacterial preparations and 0.01 to 0.02 times the equivalent of trace elements for fermentation to the crushed high-fiber feed component A in step 1), Ferment for 48-72 hours under the condition of 28-32 DEG C, and then freeze-dry to obtain the high-fiber feed component A fermented by the bacteria preparation.

[0041] 3) Air-dry the high-fiber feed component A fermented with the bacterial preparation obtained in step 2) at a temperature of 55-60° C. to obtain the high-fiber feed component A fermented with the bacterial preparation.

[0042] The fermented bacteria preparation of the present invent...

Embodiment 2

[0045]The enzymolysis high-protein feed B of the present invention is composed of 43-67 parts of soybean meal and 33-55 parts of cotton meal, which are uniformly mixed after enzymolysis reaction.

[0046] The preparation method of enzymolysis soybean meal and cotton meal of the present invention is:

[0047] 1) Raw material pretreatment: crush soybean meal and cotton meal through a 5-mesh sieve, add ethanol with a concentration of 70% according to the solid-liquid ratio of 1:4-6, soak for 2-5 hours, filter, put the filter residue in an autoclave, Cook at 115°C for 20 minutes, dry, crush and pass through a 5-mesh sieve to obtain pretreated soybean meal and cotton meal.

[0048] (2) Enzymolysis: Add sterile water to the pretreated soybean meal and cotton meal, the amount of sterile water added is 150-200% of the mass of soybean meal, stir evenly, and then add 1.5-5% enzyme of soybean meal and cotton meal The preparation is placed at 55-60° C. for enzymolysis for 24-48 hours, dr...

Embodiment 3

[0051] The preparation method of probiotic nutrient sustained-release pellets of the present invention is:

[0052] a. Weigh active probiotic nutrients, quinocetone, zeolite powder, talc powder and croscarmellose sodium, and mix them in a wet granulator, set the speed at 600-800 rpm, and stir for 5-10 minutes.

[0053] b. Add the soft material made of hydroxypropyl methylcellulose, set the stirring speed at 1000-1200rpm, the shearing speed at 600-800rpm, add the binder aqueous solution with a concentration of 1% w / w, and prepare the soft material for 3-5 minutes.

[0054] c. Extrude and spheronize the soft material at an extrusion speed of 40-50rpm to prepare pellets, sieve with a sieve plate aperture of 0.3-0.4, a spheronization speed of 1700-1900rpm, and a spheronization time of 3-5 minutes to obtain sustained-release pellets.

[0055] d. Dry the pellets prepared in step c below 55-65°C and pass through a 50-100 mesh sieve.

[0056] e. Repeat steps b-d for 2-3 times, and pa...

Abstract

The invention relates to a preparation and application of feed for improving the live pig meat quality, and belongs to the field of feed. The feed of the invention consists of a fermented bacterial preparation, a bacterial preparation slow-release pellet, a fermented high-fiber feed ingredient A, an enzymolysis high-protein feed B, and an enzyme preparation. The feed of the invention can maximizethe digestion and absorption of the feed by livestock through the enzyme preparation and the bacterial preparation, and the application of the feed is reduced. The protein content of the high-fiber feed component A in the feed of the invention after bacterial preparation treatment is increased by about 12.5-13.4%, the high-protein feed B treated with the enzyme preparation is decomposed into peptides and small peptides with a molecular weight of 5 kD-30 kD, the quality of the feed is significantly improved, the absorption of proteins by livestock is more facilitated, and a utilization rate ofthe feed is improved. Through feeding the feed of the invention, the immunity of livestock can be improved, a fattening rate of livestock is accelerated and a ratio of mass to lean meat of livestock is improved, and thereby the feed has wide application prospects.

Description

technical field [0001] The invention relates to the preparation and application of a feed for improving the quality of raw pork, belonging to the field of feed. [0002] technical background [0003] Most of the common livestock feed products in our country are mainly carbon water raw materials such as bran and corn. A common feature of the above carbon water raw materials is that they contain a large amount of cellulose, mannan and Polysaccharides such as xylan will produce flatulence in mammals for a long time, affect the gastrointestinal health of mammals, and adversely affect the growth of mammals. High-fiber feed can be fermented by microorganisms to saccharify the high-fiber in the feed and increase the palatability of the feed. The lactic acid produced during fermentation increases the flavor of the feed, which is conducive to the digestion and absorption of the feed. [0004] Enzyme preparations can improve the utilization rate of animal feed, eliminate anti-nutriti...
