Abstract

The invention relates to a preparation method of a stable triazinone anticoccidial drug dry suspension. The triazinone anticoccidial drug is uniformly dispersed in a drug auxiliary material and a carrier through optimization of a suspending aid, a surfactant and a dispersing agent, the dry suspension is prepared through an extrusion spheronization process, and the preparation can be uniformly suspended in water according to a certain proportion for animals to drink. All auxiliary materials involved in the invention are easy to obtain, the cost is low, the preparation process is simple, the product quality is stable, the suspension effect in water is good and the like, and compared with a premix and a solution, the clinical application advantages are more obvious.

Description

technical field [0001] The invention relates to a formulation and a preparation method of a dry suspension of triazinone anticoccidial drugs. Background technique [0002] Coccidia mostly occur in warm and humid seasons, but under large-scale feeding conditions, chickens and pigs of all ages can be infected with coccidia. Chickens of introduced breeds are more susceptible than local chickens, and yellow chickens and local pigs are more susceptible due to breeding The way and the structural characteristics of the livestock house are the animal groups with a high incidence of coccidia. Chicken coccidiosis mostly occurs in poultry at the age of 15 to 50 days, and chickens over 3 months old are less likely to get sick, and adult chickens generally do not get sick. A kind of intestinal parasitic protozoan disease, which mainly harms piglets aged 7-21 days, and is characterized by diarrhea in piglets, showing symptoms of acute or chronic enteritis. The disease is most likely to ...
