Description

[0001] The invention relates to parasitology, in particular to a method of treating ectoparasitosis in chickens and can be used in veterinary medicine.

[0002] Chickens are affected by a number of species of ectoparasites, which parasitize in feathers, down, skin and scales. More frequently, among the malophagous, the following species of permanent ectoparasites have been recorded: Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniodes dissimilis, Lipeurus caponis, Menopon gallinae, Menacanthus cornutus, Menacanthus pallidulus and temporary ectoparasites - fleas Ceratophylus gallinae, C. hirundinis, gamazizi mites - Fermanyssus gallinae, D. hirundinis.

[0003] These parasites lead to a considerable decrease in the daily weight gain of birds, negatively influence egg production, plumage and meat quality, and can often even cause their death, which brings considerable damage to the livestock sector and the national economy.

[0004] A method of prophylaxis and treatment of ectoparasites in chickens is known, which includes spraying chickens with a 5% aqueous solution of the extract obtained from the aerial parts of dried tobacco in a dose of 50 ml per chicken. For prophylaxis, the treatment is carried out in one session, and for treatment - in two sessions, with an interval of 14 days [1]. The biologically active natural extract is obtained from plant raw materials.

[0005] The problem solved by the proposed invention consists in expanding the arsenal of preparations of natural origin with antiparasitic action, which ensures the absence of toxicity of the preparations on the animal body and of restrictions on the use of meat products and by-products.

[0006] The problem is solved in that the method includes treating chickens by spraying with a 5% aqueous solution of the extract obtained from the aerial part of dried wormwood Artemisia absinthium L. in a dose of 50 ml per chicken. The treatment is carried out in two doses with an interval of 14 days.

[0007] The result of the invention is to ensure a considerable reduction in the damage caused by ectoparasites. The 5% aqueous solution of the extract obtained from the aerial parts of dried wormwood (Artemisia absinthium) in the dose used is harmless to birds. The arsenal of preparations of natural origin with antiparasitic action in chickens has been expanded. The method is not expensive and does not require a large amount of work, and when applying it there are no restrictions on the use of products and by-products obtained from treated birds.

[0008] The preparation is a biologically active natural extract obtained from wormwood (Artemisia absinthium), which was named Ectostop-P. The preparation was obtained by the collaborators of the Laboratory of Parasitology and Helminthology of the Institute of Zoology of the Academy of Medical Sciences. The experiments on determining the therapeutic efficacy against ectoparasites in chickens were carried out during 2007 in the Laboratory of Parasitology and Helminthology of the Institute of Zoology of the Academy of Medical Sciences. The preparation can be obtained by the following procedure: 300 g of dried, crushed aerial parts of wormwood (Artemisia absinthium) were subjected to extraction in a volume of 1.5 l of 70% hydroalcoholic solution, for 8 hours. The operation was repeated 3 times, then the extracts were combined and distilled to dryness in a vacuum evaporator at a temperature of 50°. 28.1 g of dry residue rich in biologically active substance were obtained. The control was carried out using thin layer chromatography on Silufol plates in the solvent system chloroform: methanol = 72:25 (v/v). Aqueous solutions in concentrations of 3, 4, 5 and 6% were used for research. For example, a 5% solution is obtained from 5 g of dry residue dissolved in 95 ml of pure water.

Example 1

[0011] The experiments were carried out during 2007 in the Parasitology and Helminthology laboratory of the Institute of Zoology of the ASM.

[0012] To establish the efficacy of the Ectostop-P preparation, 5 batches of birds (2-3 year old chickens) were formed, 10 heads in each batch, spontaneously infested with ectoparasites: malophagous (Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniodes dissimilis, Lipeurus caponis, Menopon gallinae, Menacanthus cornutus, Menacanthus pallidulus), fleas (Ceratophylus gallinae, C. hirundinis) and gamazid mites (Fermanyssus gallinae, D. hirundinis).

Preventively, all the birds were examined by parasitologists according to the methods proposed by Dubinina M. (Дубинина М. Паразитологическое история птиц. М.-Л., АН СССР, 1957) and Luncaşu M. (Лункашу М. Пухоеды домый птиц и мери больша с ними. Кишинёв, Штиинца, 1978).

[0014] Batch 1 - control, infested (untreated), batch II - treated with Ectostop-P with a concentration of 3.0%, batch III - Ectostop-P with a concentration of 4.0%, batch IV - Ectostop-P with a concentration of 5.0%, batch V - Ectostop-P with a concentration of 6.0%. The Ectostop-P preparation was applied by spraying each bird separately, from the calculation of 50 ml per bird. The results obtained are presented in the table.

[0018] Each group of chickens was isolated in separate rooms. The efficacy of the preparation administered in various doses was determined after 2, 12, 24 and 72 hours after treatment. The results of the research show that in groups IV and V, where Ectostop-P was used in a concentration of 5 and 6%, a high efficacy of this preparation (90%) was achieved.

[0019] Since the Ectostop-P preparation in 5 and 6% concentration has the same therapeutic efficacy - 90%, for combating ectoparasites in chickens the Ectostop-P preparation in 5% concentration is recommended.

[0020] After 14 days, the Ectostop-P preparation was repeatedly administered in a concentration of 5% in a dose of 50 ml to each bird, and after 72 hours, an efficacy of the preparation of 100% was established.

[0021] Therefore, it was found that the Ectostop-P preparation administered to chickens possesses high therapeutic efficacy against various species of ectoparasites: malophagous (Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniodes dissimilis, Lipeurus caponis, Menopon gallinae, Menacanthus cornutus, Menacanthus pallidulus), fleas (Ceratophylus gallinae, C. hirundinis) and gamazid mites (Fermanyssus gallinae, D. hirundinis).

[0022] The clinical condition of the chickens after treatment improved, the birds calmed down, and began to eat more.

[0023] The given method ensures a considerable decrease in the damage caused by ectoparasites.

[0024] The Ectostop-P preparation in a concentration of 5% is not toxic, for these reasons its overdose does not produce adverse effects, its administration does not require a large volume of work and there are no restrictions on the use of products and by-products obtained from poultry processed with this preparation.
