Problems solved by technology

There are certain problems in the quality of pellet feed, which are mainly manifested in: 1. Unbalanced feed nutrition and high cost of feed raw materials; 2. The finished feed is easily broken, high powder content, and poor stability in water.
Studies have shown that the appropriate crude fiber content in the feed can improve the palatability of the feed, promote food intake, and improve the cohesiveness of the pellet feed, but the use of crude fiber is limited due to the problem of indigestibility. Therefore, in order to make the feed In order to achieve the optimal level of utilization rate, under normal circumstances, the addition of feed materials with a wide range of sources and low prices and high crude fiber content in the feed will be reduced, and the amount of feed materials with high protein content and high fat content will be increased, so that , not only lead to an increase in feed cost, but also the appropriate crude fiber content in the feed is contradictory to the feed utilization rate. When the crude fiber content in the feed is the most appropriate, it will lead to low feed utilization rate. It will lead to an increase in feed cost, and also affect the external quality of the feed, making the feed easily broken and high in powder content
The above situation not only weakens the market competitiveness of the enterprise, but also leads to the decline of the economic benefit of the enterprise.

Embodiment 1

[0019] A method for preparing pig feed, said method comprising the steps of:

[0020] (1) Weighing of raw materials: 400-500 parts of soybean meal, 320 parts of corn, 160 parts of bran, 120 parts of rice bran, after crushing, add 40 parts of shrimp shell, 100 parts of lotus leaf, 10 parts of sophora flavescens, 10 parts of honeysuckle, cat's claw 10 parts grass, 3 parts humic acid, 5 parts glucomannan, 3 parts fat emulsifier, 1 part premix;

[0021] (2) Crushing of raw materials: Add the raw materials weighed in the above step (1) into the crushing chamber with a pulverizer, and then add 50 parts of water to pulverize for 15 minutes;

[0022] (3) Material homogenization: transport the pulverized material in step (2) to a homogenizer for homogenization for 30 minutes;

[0023] (4) Material drying: transfer the homogenized material in step (3) to a freeze dryer for freeze drying to obtain pig feed.

Embodiment 2

[0025] The difference between this example and Example 1 is that the raw materials of this example are weighed according to the following proportions: 500 parts of soybean meal, 400 parts of corn, 250 parts of bran, and 180 parts of rice bran. 160 parts of leaves, 20 parts of Sophora flavescens, 20 parts of honeysuckle, 20 parts of cat's claw, 4 parts of humic acid, 10 parts of glucomannan, 8 parts of fat emulsifier, 3 parts of premix.

[0026] In this embodiment, the amount of water added during pulverization is 60 parts, the pulverization time is 20 minutes, and the time between homogenization is 20 minutes.

Embodiment 3

[0028] The difference between this example and Example 1 is that the raw materials of this example are weighed according to the following proportions: 450 parts of soybean meal, 350 parts of corn, 200 parts of bran, 150 parts of rice bran, 50 parts of shrimp shell, and 130 parts of lotus leaf , 15 parts of sophora flavescens, 15 parts of honeysuckle, 15 parts of cat's claw, 5 parts of humic acid, 8 parts of glucomannan, 5 parts of fat emulsifier, and 2 parts of premix.

[0029] In this embodiment, the amount of water added during pulverization is 80 parts, the pulverization time is 15 minutes, and the time between homogenization is 30 minutes.

Abstract

The present invention provides a preparation method of a pig feed. The preparation method comprises the following steps: (1) raw material weighing; (2) raw material crushing: the weighed materials in the step (1) are added into a crushing chamber of a crusher, then 50-80 parts of water is added, and the materials are crushed for 15-30 minutes; (3) material homogenizing: the crushed materials in the step (2) are transported into a homogenizer to be homogenized for 20-30 minutes; and (4) material drying: the homogenized materials in the step (3) are transported into a freeze dryer to be freeze-dried to obtain the pig feed. The method is strict in material selection and reasonable in matching. Each of the raw materials consisting the feed are crushed, the crushed materials are homogenized, and the homogenized materials are subjected to the freeze-drying treatment, so that the feed is reduced in broken rate and powder containing rate, good in rehydration, less in nutrient loss, improved in quality, and reduced in the raw material costs.

Description

technical field [0001] The invention relates to the technical field of livestock breeding feed, in particular to a preparation method of pig feed. Background technique [0002] With the continuous development of the feed industry and animal husbandry, high-quality pellet feed is becoming more and more popular in the market, especially in the aquaculture industry, the demand for high-quality, high-paying aquatic feed is also rising, feed processing enterprises It will also improve the quality of feed as a constant pursuit of the goal. Pellet feed has a series of advantages such as comprehensive nutrition, good palatability, shortening feeding time, avoiding picky eaters, convenient transportation, storage, and mechanization of feeding, and its proportion in the total feed is constantly increasing. There are certain problems in the quality of pellet feed, which are mainly manifested in: 1. Unbalanced feed nutrition and high cost of feed raw materials; 2. The finished feed is ...
