Double-solvent long-acting combined drug for killing parasites on body surfaces of livestock and poultry

Abstract

The invention belongs to the technical field of design, research and development of veterinary drugs in the animal husbandry, and particularly discloses a double-solvent long-acting combined drug forkilling parasites on the body surfaces of livestock and poultry. The combined drug comprises the following components: 1.5%(w / v) of lambda-cyhalothrin, 6%(w / v) of 2-isopropoxybenzene-N-methylcarbamate, 0.2%(w / v) of phoxim, 84.8%(w / v) of food-grade white oil and the balance of a acetone substitute 15%(V / V); a preparation method thereof comprises the following steps: sequentially dissolving the lambda-cyhalothrin and the 2-isopropoxybenzene-N-methylcarbamate into the acetone substitute, and thoroughly stirring; adding the phoxim, and uniformly mixing; finally, with a mixture as a solute, dissolving again in the white oil; uniformly mixing the components in a mixer to obtain a combined drug solution with the concentration of 7.7%. The oil-type combined drug is insoluble in water, has very good adsorption performance, can form a difficultly removed drug film after being sprayed on the body surfaces of the livestock and poultry, slowly releases the drug effect, and can effectively kill theparasites on the body surfaces of the livestock and poultry.

Description

technical field [0001] The invention belongs to the technical field of design and research and development of animal husbandry veterinary drugs, and specifically discloses a long-acting combined drug for expelling and killing epiparasites of livestock and poultry prepared by two solvents, which is mainly used for expelling hard ticks and soft ticks that live on the epiparasites of livestock and poultry. Ticks and other parasites. Background technique [0002] In animal husbandry production, livestock and poultry parasitic diseases seriously affect the production performance of livestock and poultry. For example, hard ticks, soft ticks, fleas, lice, ticks, mosquitoes, flies and other ectoparasitic diseases of livestock and poultry are particularly harmful. In addition to absorbing the blood of livestock and poultry, causing itching, dermatitis, anemia, etc., more importantly, they can also spread Diseases, prevention and treatment of ectoparasitic diseases are relatively dif...

Problems solved by technology

The main reason is that although the insecticides currently used are effective, most of them are water agents, and the use concentration is low, and they are separated from the actual production environment in production practice, and it is not easy to keep them on the carcass for a long time, so the validity period is only about two weeks

If the concentration is too high, it is easy to cause poisoning, so no ideal drug for preventing and controlling ectoparasites has been found so far.
