Problems solved by technology

[0004] However, the existing tributyrin has its own defects: on the one hand, it exists in a liquid form, and it is very inconvenient to add and use in animal feed, and it is easy to oxidize and rancid, which is not conducive to transportation and storage; on the other hand, its existence Cheese rancid smell, direct feeding will seriously affect the animal's feeding performance
Based on the above-mentioned many defects, tributyrin is still difficult to be popularized and applied in large quantities in actual production.

Embodiment 1

[0027] 1) Weigh 50kg of granular silica gel into the fluidized granulation dryer, and control the temperature of the inlet and outlet air at about 25°C;

[0028] 2) adjust the peristaltic pump to extract 50kg of liquid tributyrin for feeding, the rotating speed of the peristaltic pump is 150r / min, atomize and spray into the fluidized bed from the top, so that the white carbon black can fully and evenly absorb tributyrin;

[0029] 3) Spray 60g of flavoring agent evenly into the reactant of step 2), and stir while spraying;

[0030] 4) The mixture obtained in step 3) is sieved through a 60-mesh sieve to obtain a tributyrin solid granular preparation for feeding.

Embodiment 2

[0032] 1) Weigh 50kg of granular silica gel into the fluidized granulation dryer, and control the temperature of the inlet and outlet air at about 25°C;

[0033] 2) Adjust the peristaltic pump to extract 65kg of liquid tributyrin for feeding, the rotating speed of the peristaltic pump is 200r / min, atomize and spray into the fluidized bed from the top, so that the white carbon black can fully and evenly absorb tributyrin;

[0034] 3) Spray 100g of fragrance evenly into the reactant of step 2), and stir while spraying;

[0035] 4) The mixture obtained in step 3) is sieved through a 60-mesh sieve to obtain a tributyrin solid granular preparation for feeding.

Embodiment 3

[0037] 1) Weigh 50kg of granular silica gel into the fluidized granulation dryer, and control the temperature of the inlet and outlet air at about 25°C;

[0038] 2) Adjust the peristaltic pump to extract 35kg of liquid tributyrin for feeding, the rotating speed of the peristaltic pump is 120r / min, atomize and spray into the fluidized bed from the top, so that the white carbon black can fully and evenly absorb tributyrin;

[0039] 3) Spray 50g of fragrance evenly into the reactant of step 2), and stir while spraying;

[0040] 4) The mixture obtained in step 3) is sieved through a 60-mesh sieve to obtain a tributyrin solid granular preparation for feeding.

Abstract

The invention discloses a tributyrin solid granular preparation. Liquid tributyrin is absorbed or bonded on the surface or in pores of a granular white carbon black silica gel. The preparation disclosed by the invention realizes solid granular treatment of the liquid tributyrin, increases stability and bioactivity of tributyrin, and enables tributyrin to have a controlled sustained release effect in animal intestines.

Description

technical field [0001] The invention relates to a feed additive, in particular to a tributyrin solid granular preparation and a preparation method and application thereof, belonging to the field of animal feed. Background technique [0002] Finding green and safe feed additives is the focus of current research on animal feed and healthy breeding. Among them, since tributyrin can be used as the main energy source, maintain the stability of the intestinal environment, and has the characteristics of not being decomposed by gastric acid after passing the stomach, it is considered to be a potential substitute for antibiotic growth promoters. [0003] Tributyrin is decomposed into glycerol and butyric acid by pancreatic lipase in the intestinal tract of animals. Butyric acid, as an organic acid, can effectively inhibit intestinal harmful bacteria such as Escherichia coli, Salmonella, Bacillus cereus, Clostridium, etc. Partially replace antibiotics. At the same time, as a 4-carbon...
