Description

Technical Field

[0001] This invention relates to the technical field of pig feed formulation, specifically to a cost-saving mixed pig feed formulation and its application method. Background Technology

[0002] With the development of the livestock industry, my country's total output of meat, eggs, and milk has exceeded 140 million tons for eight consecutive years. China ranks first in the world in meat and poultry egg production, and raises nearly 50% of the world's pigs. Therefore, the demand for livestock feed is enormous. China's annual grain production is 650 million tons, with imports of 165 million tons, of which 340 million tons are for feed, accounting for over 40%. Developing feed protein from grain is not in line with China's national conditions under the current international situation. Finding suitable substitutes for feed grain would be a solution to China's food security problem. my country's feed protein production needs to seek a new resource-based route, developing integrated technologies for the treatment and resource utilization of straw, grain processing waste, and aquatic plants, and developing a feed protein manufacturing route with Chinese characteristics. The protein content of straw has been significantly increased, already meeting the feeding requirements of ruminants such as cattle and sheep, and can subsequently meet the nutritional needs of pigs and animal offspring. Summary of the Invention

[0003] The purpose of this invention is to provide a cost-saving mixed pig feed formula and its application method to overcome the above-mentioned defects in the prior art.

[0004] The present invention is achieved through the following technical solution.

[0005] A cost-saving mixed pig feed formula includes: silage, corn feed, soybean meal, wheat middlings, rice bran, limestone powder, dicalcium phosphate, soybean oil, piglet concentrate premix, 70% lysine, sodium chloride, threonine, methionine, milk flavor 366, and phytase.

[0006] This invention also includes a method for using a cost-saving mixed pig feed formulation, comprising the following steps:

[0007] Step 1: Silage Processing

[0008] Raw material processing:

[0009] (6) Using corn or rice straw as raw material, the straw is fully crushed by a crusher to ensure that the raw material particles are as small as possible, thereby improving the fermentation effect and efficiency;

[0010] (7) Place the crushed straw into a silage pit or other sealed fermentation facility. The straw raw material should be spread out layer by layer and fully compacted to avoid air and bacteria inside, which could lead to spoilage.

[0011] (8) When the raw materials are filled to the mouth of the silage pit, the raw materials in the middle should be about 100 cm higher than the mouth of the pit. Cover the raw materials with 10 cm thick green grass, then cover with plastic film, and cover the plastic film with 50 cm thick soil and tamp it down. Dig a drainage ditch around the silage pit to prevent rainwater from seeping into the pit. In areas with a lot of rain, build a large shed on the silage pit to shelter from the wind and rain.

[0012] (9) After the silage pit is filled, it is important to check it. After a few days, the raw materials will sink, and cracks will often appear on the top of the pit. Soil should be added and compacted in time. Livestock should not be allowed to move around in the silage pit to avoid trampling on it.

[0013] (10) After the silage has fully fermented, take it out.

[0014] Step Two: Refined Material Processing and Synthesis

[0015] Main ingredients and proportions of concentrated supplementary feed: Corn feed - 42.8%, soybean meal - 32%, wheat middlings - 12%, rice bran - 6%, limestone powder - 2%, dicalcium phosphate - 1.3%, soybean oil - 1.5%, piglet concentrate premix - 1.0%, 70% lysine - 0.53%, sodium chloride - 0.5%, threonine - 0.16%, methionine - 0.11%, milk flavor 366 - 0.05%, phytase - 0.05%.

[0016] Step 3: Mix silage and concentrate feed in the specified proportions.

[0017] The above-mentioned silage and concentrate feed are mixed in a ratio of 1:1 and 1:2 to make complete feed. The feed mixed in a ratio of 1:1 is suitable for piglets and sows, and the feed mixed in a ratio of 1:2 is suitable for fattening pigs.

[0018] Step 4: Feed the animals according to scientific feeding standards.

[0019] The beneficial effects of this invention are:

[0020] The present invention provides a cost-saving mixed pig feed formula and its application method, which is made by mixing silage with concentrated supplementary feed in a certain proportion. While meeting the nutritional needs of pig growth, it reduces the amount of basic daily feed and greatly reduces breeding costs.

[0021] The present invention discloses a cost-saving mixed pig feed formula and its application method. By feeding the pigs with a mixture of complete feed, the cost of raising pigs can be reduced while ensuring good daily weight gain, feed conversion ratio and sludge-to-meat ratio. This facilitates the operation of the pig farming industry and complies with the national policy on pig farming. It solves the problem of feed feeding and meets the nutritional needs of pigs, livestock and animal offspring. Detailed Implementation

[0024] This invention also includes a method for using a cost-saving mixed pig feed formulation, comprising the following steps:

[0025] Step 1: Silage Processing

[0026] Raw material processing:

[0027] (11) Using corn or rice straw as raw material, the straw is fully crushed by a crusher to ensure that the raw material particles are as small as possible, thereby improving the fermentation effect and efficiency;

[0028] (12) Place the crushed straw into a silage pit or other sealed fermentation facility. The straw raw material should be spread out layer by layer and fully compacted to avoid air and bacteria inside, which could lead to spoilage.

Cover the raw materials with 10 cm thick green grass, then cover with plastic film, and cover the plastic film with 50 cm thick soil and tamp it down. Dig a drainage ditch around the silage pit to prevent rainwater from seeping into the pit. In areas with a lot of rain, build a large shed on the silage pit to shelter from the wind and rain.

[0030] (14) After the silage pit is filled, it is important to check it carefully. After a few days, the raw materials will sink, and cracks will often appear on the top of the pit. Soil should be added and compacted in time. Livestock should not be allowed to move around in the silage pit to avoid trampling on it.
