Description

The invention relates to a repellent for the protection of livestock which is attacked by double-winged insects, which results in a reduction in their performance - and often the transmission of a number of diseases.

Livestock such as cows, heifers, horses are mainly attacked by horseflies (Tabanidae), mosquitoes (Culicidae), toadstools (Simuliidae) and often even midges (Ceratopogonidae).

Blood sucking occurs weakening individuals, disturbance in grazing and worsening health.

Insect harassment in cattle results in a decrease in milk yield, reduction in meat growth, and in draft horses, for example, when weighing wood, lower performance is performed, while particularly sensitive horses cannot work in the field at times of mass occurrence of double-winged insects.

The most important diseases that may be transmitted by stinging insects include spleen, robin, mastitis, eye infections, intestinal infections, myxomatosis, foot-and-mouth disease, pasteurellosis, brucellosis, anaplasmosis, onchocercosis, filariasis, infectious .emia, influenza and infectious keratoconus next.

Flying, blood-sucking double-winged insects thus cause considerable losses and therefore the possibilities of reducing them by treating livestock with insect repellents are being verified.

For example, the successful use of OXAMATE (pentyl and octyl ester of N, N-diethyloxaminic acid J for cattle protection is known, SCHRECK and colleagues (J. Med. Eent. 13, 1976 No. 1, pp. 115-118) verified the use of alcoholic solutions. Ν, Ν-diethyl m-toluamide (DETA), and 2-hydroxyethylcyclohexanecarboxylate.

Aerosol DETA used BLUME (J. Econ. Ent. 64, 1971 No. 5, p. 1 193-196).

Other work describes the use of solutions and emulsions of β-naphthyl methyl ether, diphenyloxide and terpineol, as well as emulsions of hexamethylene benzamide in combination with polychlorpine, an emulsion of carboxide (dihexamethylenecarbamide). SU AO 596 239 discloses an electrostatic spray repellent composition based on a solution of the repellent in petrolatum oil and butanol. Also disclosed is a combination of acetyltetrahydroquinoline with dinaethyl tthalate and capric acid diethylamide in a 3% aqueous emulsion.

Repellent preparations are usually applied to livestock by coating or spraying or spraying. by electrostatic spraying in the form of an aerosol. Some products are applied to blankets to cover the animals. The most common is the method of application by spraying the emulsions of the repellent formulation in water, but this has the disadvantage of having to transport a large volume of the formulation to remote locations.

This disadvantage is overcome by the preparation according to the invention based on the preparation of a repellent concentrate which, when poured into water, spontaneously forms an emulsion. As a repellent! preferably, the compound 2-phenylpropanediol 1,3 (FPD), DETA, or a mixture thereof, exhibiting a synergistic effect may be used.

The following examples illustrate the invention.

Example 1 g DETA, 20 g FPD, 35 g oxyethylenated unsaturated fatty acid, 15 g ethyl alcohol 96.5%, 8.35 g petrolatum oil, 1.5 g oleic acid and 0.15 g triethanolamine 100% are mixed and perfectly mixed homogenizes. Prior to use, 1 part of the repellent concentrate is poured with stirring into 3 parts of water to form a repellent emulsion suitable for spraying or spreading.

Example 2 g of DETA, 35 g of oxyethylenated unsaturated fatty acid, 15 g of ethyl alcohol 96.5%, 8.35 g of petrolatum oil, 1.5 g of oleic acid and 0.15 g of triethanolamine 100% are gradually mixed and thoroughly homogenized. Dilution is performed as in Example 1.

Example 3 g of DETA, 20 g of FPD, 40 g of oxyethylene fatty acid, 16.7 g of petrolatum oil, 3 g of oleic acid and 0.3 g of triethanolamine 100% are mixed and perfectly homogenized. Dilution is performed as in Example 1.

Example 4 g of DETA, 20 g of FPD, 35 g of sorbitan monolaurate, 16 g of petrolatum oil and 9 g of polyoxyethylene sorbitan monostearate are successively mixed and thoroughly mixed. 1 part of the concentrate is poured into 4 parts of water while stirring and an emulsion suitable for spraying or coating is formed.

The efficacy of repellent preparations has been verified by a biological experiment in the field. The repellent formulation was sprayed onto the hair of a cow in an amount of 1 liter of emulsion per cow. Repellent efficacy was monitored on one half of the cow body (50% of the pieces on the left half, 50% on the right half). For horses, the application was done by sponge painting on the places most often infected with stinging insects. 300 ml of repellent formulation was applied to one horse.

An average repellent activity of 48 hours was found in cows treated with the repellent formulation of Example 2. The horses treated with the repellent formulation of Example 1 had an average efficacy of 24 hours. This difference in efficacy is mainly influenced by the horse's assessment

24B worked hard, sweating, which affected the evaporation of the active substance and its washing with sweat.

The repellent formulation of Example 1 was sprayed with 25 dairy cows for 62 days, repeated every 48 hours. Compared to the control herd, the milk yield of the treated cows increased by 9.7% when compared to the milk of 4% fat and the total milk fat increased by 11.9 rel. %.

The repellent formulation of Example 2 was sprayed with 16 heifers for 66 days, repeated spraying.

B every 48 hours. Compared to the control herd, the average live weight of the package increased by 5 kg.

The repellent formulation of Example 1 was treated with 4 horses for 66 days, repeated once every 24 hours. Compared to the control group of horses, the treated horses showed an increase of 21.656 m ^{3 of} approached wood in 24 hours per 1 horse.

The examples given are sufficient to illustrate the possibilities of using the invention and the effects of applying the repellent emulsion.
