Biological Activity

Description Decoquinate is a coccidiostat.
In vitro

Decoquinate is a feed additive intended for the control of coccidiosis, a debilitating protozoal infection in poultry. The active agent is 4-hydroxyquinoline, incorporated at 0.6 % by weight in the feed additive. Evidence generated at the time of its introduction suggests that a product delivering 20-40 mg of decoquinate per kg complete feed is effective as a coccidiostat for chickens. Decoquinate plays a role in the asexual propagation of coccidium. It will stop the growth of ascospore by disturbing the DNA synthesis. Decoquinate acts on the early living period of coccidium, so it can prevent the harm of the fowl's intestinal wall. [1]

In vivo Decoquinate Premix can be absorbed fastly. It can reach the virtual concentration within 1 hour, and reach the highest concentration after 3 days. The NOEL of 15 mg/kg bw/day may be used as the basis for setting an acceptable daily intake (ADI) for decoquinate. [1]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
