Problems solved by technology

Among them, pellet feed pulverization not only affects the forming rate of pellet feed products, but also increases the energy consumption of feed pellets and increases the production cost of feed
On the other hand, the use of pellet feed with high powder content in production can also cause respiratory diseases of pigs, affect the feed intake of pigs, and then affect the growth rate of pigs, reducing the efficiency of pig farms

Embodiment 1

[0047] A method for reducing the powder content of pellet feed, comprising the following steps:

[0048] 1.5 parts by mass of guar gum, 0.75 parts by mass of carrageenan, 0.45 parts by mass of sucrose lipid and 0.4 parts by mass of sorbitol were added to 97 parts by mass of the basic formula diet, mixed evenly, and pelleted to obtain granular feed.

Embodiment 2

[0052] From the pellet feed in Example 1 and the pellet feed in Comparative Example 1, 10 samples were randomly selected, each sample weighing 500 g, and their flour content was measured respectively.

[0053] Table 1 Powder content of pellet feed

[0054] group Flour content Comparative Example 1 3.95±0.13％ Example 1 1.17±0.13％

[0055] As can be seen from Table 1, the powder-containing rate of the pellet feed of embodiment 1 is 1.17%, and the powder-containing rate of the pellet feed of comparative example 1 is 3.95%; Compared with comparative example 1, the powder-containing rate of the pellet feed of embodiment 1 rate decreased by 70.38%. From the above results, it can be known that the present invention adds a certain proportion of guar gum, carrageenan, sucrose lipid and sorbitol in the original feed formula, which can significantly reduce the powder content of the finished pellet feed.

Embodiment 3

[0057] The pellet feed in Example 1 and the pellet feed of Comparative Example 1 were piled up in the finished feed bin simultaneously, and 10 samples were randomly selected after 5 days, each sample weighing 500g, and its powder content was measured.

[0058] Table 2 Powder content of pellet feed

[0059] group Flour content Comparative Example 1 9.36±0.58％ Example 1 4.34±0.85％

[0060] It can be known from Table 2 that the powder content of the pellet feed in Example 1 is 4.34%, and that of the pellet feed in Comparative Example 1 is 9.36%. From the above results, it can be seen that the powder content of the pellet feed will increase during the stacking process. When the pellet feed is stacked, it will absorb moisture in the air, which will increase its powder content. The invention adds a certain proportion of guar gum, carrageenan, sucrose lipid and sorbitol to the original feed formula, which can significantly reduce the pulverization rate of...

Abstract

The invention discloses a method for reducing the powder content rate of granular feed, comprising 1-2 parts by mass of guar gum, 0.5-1 parts by mass of carrageenan, 0.3-0.5 parts by mass of sucrose fat and 0.2-0.5 parts by mass of Sorbitol is added to 96-98 mass parts of the basic formula diet, and mixed evenly, so as to improve the formability and durability of the pellet feed, and then reduce the powder content of the pellet feed.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a method for reducing the powder content of granular feed. Background technique [0002] In recent years, my country's pig industry has gradually developed in the direction of scale, intensification, and specialization. In addition, domestic breeding, nutrition, disease prevention, and feeding management have gradually matured, and the growth performance of pigs has been greatly improved. Due to the characteristics of growth, oil is often added to the formula to meet the energy needs of animals; but the higher the oil content in the feed formula, the lower the stability of the pellet feed, and the looser the pressed pellets, which in turn increases the pulverization rate of the pellet feed. high. Among them, the pulverization of pellet feed not only affects the forming rate of pellet feed products, but also increases the energy consumption of feed pellets and increases the production...
