It also has preventive and therapeutic effects on zoonotic toxoplasmosis, featuring broad-spectrum, high efficiency, low toxicity, large safety range, good palatability and promotion of growth and development.
It can obviously improve the weight gain rate and feeding remuneration of rabbits and poultry. In aquatic fisheries feeding anti-disease fattening effect is obvious. It is suitable for rural scale breeding and planting development.
Uses and functions of Robenidine Hydrochloride.
As an antimicrobial agent, it is effective against staphylococcus and haemolytic streptococcus. Mainly used in the treatment of avian cholera, avian typhoid fever, fowl typhus, etc.
It is a new type of high efficient anti-coccidial drug with high efficacy, low toxicity and good palatability. It has good effect on acute or chronic chicken coccidiosis. It can significantly improve the weight gain rate and feeding remuneration of rabbits and poultry. This product is a variety of the Veterinary Pharmacopoeia of the People's Republic of China (90 years edition, a) income.
Chlorpheniramine is a low-toxicity and high-efficiency anticoccidial drug, which can be used in chicken feed, with dosage of 30-36g/t, prohibited during egg-laying period, with a withdrawal period of 7 days; it can also be used in rabbit feed, with dosage of 50-66g/t, prohibited during pregnancy, with a withdrawal period of 7 days.
Mechanism of action of Robenidine Hydrochloride.
Chlorphenylguanidine hydrochloride is a guanidine derivative. The anti-coccidial mechanism is to affect the adenosine triphosphate, interfering with the protein metabolism of coccidia, and has been widely used in the prevention and treatment of avian and rabbit coccidiosis.
The peak action of chlorproguanidine hydrochloride on coccidia is mainly in the 1st generation of schizonts (i.e., day 2 of the life cycle of coccidia). It prevents the formation of schizonts from schizonts. It has also been shown to inhibit the 2nd generation of schizonts and even the development of oocysts.
The main mechanism of action is to inhibit oxidative phosphorylation in the worm, which depletes the energy supply of the worm and inhibits the growth and reproduction of schizonts. Coccidia are slow to develop resistance to chlorproguanil, and remain effective against strains resistant to other anticoccidials. Chlorbenzylguanidine is effective against tender, stacked, giant, toxigenic, and slow and Eimeria burgdorferi coccidia.
Production Method of Bulk Robenidine Hydrochloride Powder.
Sulfaguanidine is obtained by cyclisation with acetylacetone as raw material. Sulfaguanidine, acetylacetone, sodium bisulfite, sodium hydroxide and water were put into the reaction kettle and heated to reflux for about 6h.
When crystallisation appears in the reaction solution, add acetylacetone and continue refluxing for 20 h. After recovering acetylacetone, add appropriate amount of boiling water, filter while hot, wash the filter cake with hot water, recrystallise and dry to obtain sulfadiazine dimethylpyrimidine.
