Problems solved by technology

Although adding high doses of antibiotics can promote the growth of piglets and control diseases, long-term use will have negative effects such as slow growth and low disease resistance of piglets in the late nursery or piglet stage.

preparation example Construction

[0045] Another aspect of the present invention provides a method for preparing the above nursery pig feed. In an exemplary embodiment of the preparation method of nursery pig feed of the present invention, comprising:

[0046] Step 1, crushing corn and soybean meal according to parts by mass.

[0047] Step 2: Mix the crushed corn and soybean meal with secondary powder, puffed soybean, fish meal, whey powder, soybean oil, white sugar, glucose, citric acid and benzoic acid in parts by mass, granulate for the first time, and pulverize after cooling. Get primary feed.

[0048] In step 3, the primary feed is mixed with the core feed and pelleted for the second time to obtain nursery pig feed.

[0049] Further, in step 1, the corn and soybean meal can be ground by using a 1.0-2.0MM sieve. Preferably, in order to facilitate the first granulation to obtain uniformly mixed granules of raw materials, a 1.5MM sieve can be used for pulverization.

[0050] Furthermore, the temperature ...

example 2

[0067] Example 2: In parts by mass, lysine:methionine:threonine=10:2.5:3.8.

[0068] Control group 2: in parts by mass, lysine:methionine:threonine=6:1:2.

[0069] Control group 3: in parts by mass, lysine:methionine:threonine=13:4:6.

[0070] Control group 4: in parts by mass, lysine:methionine:threonine=8:2.5:7.

[0071] Table 3 Experimental result data

[0072] Numbering Diarrhea rate (%) Example 2 3 Control group 2 6 Control group 3 5 Control group 4 6

[0073] As can be seen from the above table 3, the diarrhea rate of piglets corresponding to example 2 in the mass parts lysine 7~12 parts set in the present invention, methionine 2~3 parts, threonine 3~4.5 parts is relatively low, If it is not within the range of parts by mass defined above, the diarrhea rate will increase and the effect of suppressing diarrhea will decrease.

Abstract

The invention provides a nursery pig feed as well as a preparation method and application thereof. The feed is prepared from the following raw materials in parts by weight: 43-54 parts of corn, 4.8-6.6 parts of wheat middling, 14-23 parts of soybean meal, 3-13 parts of extruded soybeans, 2.5-3.5 parts of fish meal, 4-6 parts of whey powder, 1-2 parts of soybean oil, 2-3 parts of white sugar, 2-3 parts of glucose, 0.2-0.8 part of citric acid, 0.15-0.25 part of benzoic acid and 3-5 parts of a core material. The preparation method comprises the following steps of: crushing corn and soybean meal, uniformly mixing the raw materials except the core material, performing granulating for the first time, performing cooling, and performing crushing to obtain a primary feed; and mixing the primary feed with the core material, and performing granulation for the second time so as to obtain the nursery pig feed. The feed disclosed by the invention is used for nursery pigs, and can improve the feed intake of the nursery pigs, promote growth, improve the immunocompetence of the nursery pigs, reduce diarrhea of the nursery pigs and improve the intestinal health of the nursery pigs.

Description

technical field [0001] The invention relates to the field of pig feed preparation, more specifically, to a nursery pig feed and its preparation method and application. Background technique [0002] Nursery pigs usually refer to piglets from the stage of weaning to the end of feeding in the nursery bed. They have the characteristics of fast growth and development, high susceptibility to diseases, and need to be carefully fed. In the feeding stage, in addition to paying attention to environmental sanitation and timely group feeding, due to the immature digestive system of nursery pigs, special attention should be paid to the nutrition and raw material composition of the feed. After the piglets start eating pelleted feed after weaning, due to the immature intestinal development of the piglets, encountering greater stress, it is easy to cause diarrhea and diarrhea. [0003] At present, in order to prevent piglets from diarrhea and increase the growth rate of piglets, many farme...
