Use of isoxazoline derivatives for the treatment or prevention of arthropod infestations in poultry
The present invention relates to methods of treating or preventing arthropod infestations of poultry animals and methods of controlling arthropod infestations in poultry animal's environment by administering an isoxazoline compound of formula (I) via drinking water.
1. A method of preventing or treating an infestations of a laying hen by a temporary parasitic arthropod comprising administering via the drinking water an effective amount of
fluralaner or a salt or solvate thereof,
wherein the fluralaner is administered in two separate doses approximately 7 days apart, wherein the temporary parasitic arthropod infestation is an infestation by Dermanyssus spp. and/or Ornithonyssus spp. mites, and wherein the dose is from about 0.1 to about 10 mg/kg bodyweight.
2. The method according to claim 1 wherein the temporary parasitic arthropod is selected from poultry red mites ( Dermanyssus gallinae ), and tropical fowl mite ( Ornithonyssus bursa ).
3. The method of claim 1 wherein the temporary parasitic arthropod infestation is an infestation by Dermanyssus gallinae.
4. A method for the prevention or treatment of parasitic arthropod infestations of laying hens during the laying period comprising administering via drinking water an effective amount of
fluralaner or a salt or solvate thereof, and a pharmaceutically acceptable carrier
wherein the fluralaner is administered in two separate doses approximately 7 days apart wherein the temporary parasitic arthropod infestation is an infestation by Dermanyssus spp. and/or Ornithonyssus spp. mites, and wherein the dose is from about 0.1 to about 10 mg/kg bodyweight.
5. A method of controlling darkling beetles in the environment of poultry animals comprising administering to the poultry animals via drinking water an effective amount of
fluralaner or a salt or solvate thereof
wherein the fluralaner is administered in two separate doses approximately 7 days apart and wherein the dose is from about 0.1 to about 10 mg/kg bodyweight.
6. The method according to claim 1 wherein the effective amount is 2 times a dose of 0.5 mg/kg body weight of animals treated.
7. The method according to claim 4 wherein the effective amount is 2 times a dose of 0.5 mg/kg body weight of animals treated.
8. The method according to claim 5 wherein the effective amount is 2 times a dose of 0.5 mg/kg body weight of animals treated.
