Problems solved by technology

Glucose microcapsules with a single wall material often have problems such as incomplete coating, low rumen passage rate and small intestinal absorption rate, but the process of preparing glucose microcapsules with composite wall materials has a large viscosity between the wall materials, resulting in the prepared glucose The microcapsule product is agglomerated, the coating is incomplete, the stability is low, and the effect of passing through the rumen is not good

Abstract

The invention discloses a rumen bypass glucose microcapsule and a preparation method thereof. The glucose microcapsule of the invention can realize high effective passage rate of glucose in the rumenand can be fully absorbed in the small intestines. Adding the rumen bypass glucose microcapsule to dairy cow diet in a late perinatal period can effectively reduce the negative energy balance in earlylactation, reduce postpartum weight loss of dairy cows, and increase milk production.

Description

technical field [0001] The invention relates to the technical field of microcapsule processing. Specifically, glucose is used as core material, chitosan and polyacrylic acid resin are used as wall materials, and sodium chloride solution and ethanol solution are used as wall material solvents to prepare rumen-passing glucose microcapsules, and also relates to the preparation method of the microcapsules As well as the application as a feed additive for dairy cows in the postpartum period. Background technique [0002] Microcapsule technology uses natural or synthetic polymer film-forming materials as wall materials to encapsulate and protect the core material, thereby forming tiny solid particles. At present, there are many products or studies using microencapsulation technology to prepare animal nutritional additives, such as rumen-passed choline, rumen-passed amino acids, rumen-passed fat, etc. [0003] Insufficient dry matter intake of dairy cows after parturition, lactat...
