preparation example Construction

[0034] In a second aspect, the present invention also provides a method for preparing a solid feed, the method comprising:

[0035] (1) Spray propylene glycol onto the feed carrier raw material, and then make the propylene glycol mix with the feed carrier raw material by stirring;

[0036] (2) The resulting mixture is sealed and stored at room temperature for 6-48 hours;

[0037] Wherein, the consumption of feed carrier material and propylene glycol makes, take the total weight of solid feed as a basis, the content of feed carrier in terms of dry weight is 20-65% by weight, the content of propylene glycol is 21-75% by weight, and the content of water is 3-14% by weight.

[0038]Preferably, the amount of the feed carrier raw material and propylene glycol is such that, based on the total weight of the solid feed, the content of the feed carrier in terms of dry weight is 40-60% by weight, the content of propylene glycol is 33-55% by weight, and the content of water It is 8-14% ...

Embodiment 1

[0053] This embodiment is used to illustrate the solid feed of the present invention and its preparation method.

[0054] 100kg sugar beet granular meal (purchased from COFCO Tunhe Co., Ltd.) was pulverized, and mixed with corn starch, corn stalk powder, stone powder, and soybean meal powder in a certain proportion to obtain a feed carrier with a moisture content of 12% by weight and a particle size of 200 mesh ( The weight ratio of sugar beet meal powder, corn starch, corn straw powder, stone powder and soybean meal powder is 10:0.5:2:0.5:0.5); under the operating pressure of 1.5MPa, 67kg of propylene glycol is evenly sprayed into the feed carrier by using a high-pressure water gun, Use a horizontal shaft mixer to stir the mixture of the two at room temperature, the stirring speed is 28rpm, and the time is 5min, so that the propylene glycol and the feed carrier are evenly mixed, and the mixture of the evenly mixed propylene glycol and the feed carrier is sealed and preserved. ...

Embodiment 2

[0056] This embodiment is used to illustrate the solid feed of the present invention and its preparation method.

[0057] 150kg beet granule meal (purchased from COFCO Tunhe Co., Ltd.) was pulverized, and mixed with corn starch, corn stalk powder, stone powder, and soybean meal powder in a certain proportion to obtain a feed carrier with a moisture content of 11% by weight and a particle size of 80 meshes ( The weight ratio of beet meal powder, corn starch, corn straw powder, stone powder and soybean meal powder is 10:0.5:1:0.5:0.5; 100kg of propylene glycol is evenly sprayed into the feed carrier with a high-pressure water gun under the operating pressure of 1MPa. The shaft type mixer stirs the mixture of the two at room temperature, the stirring speed is 30rpm, and the time is 10min, so that the propylene glycol and the feed carrier are evenly mixed, and the mixture of the evenly mixed propylene glycol and the feed carrier is sealed and stored. 12 hours, so that the propylen...

Abstract

The invention relates to the field of feeds, and discloses a solid feed. The solid feed is prepared from the following components according to dry weight on the basis of total weight of the solid feed: 20 to 65wt% of feed carrier, 21 to 75wt% of propylene glycol and 3 to 14wt% of water. The invention also relates to a preparation method of the solid feed and the solid feed prepared by the preparation method. The preparation method has the advantages that the operation is convenient, the pollution to environment is avoided, liquid propylene glycol is converted into solid propylene glycol powder with stable property and good fluidity, the problem of perfusion of the liquid propylene glycol for dairy cows is solved, and the high labor intensity caused by perfusion of the propylene glycol is avoided; the problem of inconvenience in long-distance transportation of the liquid propylene glycol is solved, and the solid feed can be directly fed to livestock conveniently or be used as a raw material to conveniently prepare complete feeds.

Description

technical field [0001] The invention relates to the field of feed, in particular to a solid feed and a preparation method of the solid feed. Background technique [0002] With the rapid development of the breeding industry, the number of dairy cows in my country is increasing, and high yield, stable yield and health have become the ultimate goal of dairy cow breeding. With the increase of milk production of dairy cows, high-yielding dairy cows in the early stage of lactation are often in a state of negative energy balance because the energy they eat cannot meet the needs of lactation, which is likely to cause other metabolic diseases such as ketosis, resulting in deterioration of the health status of dairy cows and production performance decline. Ketosis is one of the main nutritional and metabolic diseases that seriously endanger the health and production performance of dairy cows, resulting in a significant decrease in milk production (about 15%), delayed estrus, reduced ...
