Embodiment 1

[0104] After drying 20kg of bagasse in a hot air oven, pulverize it through a pulverizer to obtain bagasse powder with a moisture content of 8wt% and a particle size of 20 meshes; pulverize 80kg of beet pulp particles through a pulverizer to obtain a moisture content of 12wt%. , particle size is 50 purpose beet meal powder; bagasse powder and sugar beet meal powder are placed in the mixer and mixed, and the mixing time is 1min to obtain composite carrier powder; 67kg propylene glycol is evenly sprayed on the obtained composite carrier In the powder, use a feed mixer to stir the mixture of propylene glycol and the obtained composite carrier powder at room temperature at a speed of 28 rpm for 15 minutes, and seal and store the mixture of propylene glycol and carrier after mixing evenly. for 24 hours, so that the propylene glycol is completely absorbed by the feed carrier, and then the sealed and stored mixture is stirred at a speed of 32rpm for 3 minutes, so as to break all the l...

Embodiment 2

[0108] After drying 50kg of bagasse with a drum, it is crushed by a kneading cutter to obtain bagasse powder with a moisture content of 5wt% and a particle size of 50 meshes; 100kg of beet pulp particles are crushed by a pulverizer to obtain a moisture content of 11wt%. , particle size is 80 purpose beet meal powder; bagasse powder and sugar beet meal powder are placed in the mixer and mixed, and the mixing time is 2min to obtain composite carrier powder; 180kg propylene glycol is evenly sprayed on the obtained composite carrier In the powder, use a feed mixer to stir the mixture of propylene glycol and the obtained composite carrier powder at room temperature at a speed of 28rpm, and the stirring time is 25min. The mixture of propylene glycol and carrier after mixing is sealed and preserved. For 48 hours, so that the propylene glycol is completely absorbed by the feed carrier, and then the sealed and stored mixture is stirred at a speed of 28rpm for 3 minutes, so as to break a...

Embodiment 3

[0112] After drying 10kg of bagasse in a fluidized bed, pulverize it through a pulverizer to obtain bagasse powder with a moisture content of 10wt% and a particle size of 10 meshes; pulverize 90kg of sugarcane meal particles through a pulverizer to obtain a moisture content of 14wt% %, a particle size of 20 mesh sugar beet meal powder; bagasse powder and sugar beet meal powder are placed in a mixer for mixing, and the mixing time is 2min to obtain a compound carrier powder; 67kg of propylene glycol is evenly sprayed on the obtained compound carrier powder In the carrier powder, use a feed mixer to stir the mixture of propylene glycol and the obtained composite carrier powder at room temperature at a speed of 32 rpm for 15 minutes, and seal the mixture of propylene glycol and carrier after mixing uniformly. The time is 6 hours, so that the propylene glycol is completely absorbed by the feed carrier, and then the sealed and stored mixture is stirred at a speed of 28 rpm for 5 min...

Abstract

The invention relates to solid feed containing propylene glycol. The solid feed contains the following raw materials in percentage by dry weight: 40wt%-66wt% of compound feed carriers, 24wt%-55wt% ofpropylene glycol and 4wt%-10wt% of water, wherein the compound feed carriers contain a disperse carrier and an absorption carrier. The invention also relates to a method for preparing the solid feed containing the propylene glycol, and the method comprises the following steps: pulverizing the disperse carrier and the adsorption carrier separately, and then performing mixing to obtain the compoundfeed carriers; spraying the compound feed carriers with the propylene glycol, performing sealed preservation for 2-48 hours at room temperature after mixing, and breaking down the obtained solid feedcontaining the propylene glycol selectively to obtain a granular or powdered solid feed product. The preparation method provided by the invention is simple and convenient in operation and can solve the problem that liquid state propylene glycol needs to be drenched. Furthermore, the solid feed containing the propylene glycol solves the problem of inconvenience in long-distance transportation of the liquid state propylene glycol and also provides convenience for directly feeding livestock or serving as a raw material for preparing complete feed.

Description

technical field [0001] The invention relates to the field of feed. In particular, the present invention relates to solid feeds containing propylene glycol, and methods for preparing such solid feeds. Background technique [0002] With the rapid development of the breeding industry, the number of dairy cows in my country is increasing, and high and stable production has become the ultimate goal of dairy farming. 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 their lactation needs, which is likely to cause metabolic diseases such as ketosis, resulting in the deterioration of the health status of dairy cows. Production capacity is reduced. It is currently known that ketosis is one of the major nutritional and metabolic diseases that seriously endanger the health and production capacity of dairy cows. It will lead to a significan...
