Description

Slow-release mosquito and fly repellent pendant for cattle and sheep

The invention belongs to animal husbandry and veterinary medicine, in particular to the field of products for preventing harmful flying insects for open cattle and sheep.

Mosquitoes and flies can affect the feeding of cattle and sheep, interfere with rest, and spread various diseases, especially bovine myiasis, which is the most common and most harmful parasitic disease of yaks and cattle. Animals such as sheep, horses, and deer also occur from time to time, and can also infect people. The harm of psoriasis is mainly in the larval stage, and the larvae are parasitic in animals. The life history of the yak psoriasis is that the yak psoriasis produces maggots in the thin skin such as the armpit and groin of the yak body every summer. The maggots penetrate the skin and enter the body and gradually grow up. The skin gets out and falls on the grass, and it hatches for about 7 days to become a psoriasis. After mating, the psoriasis produces maggots and enters the second life cycle. Young maggots migrate and develop in the body, resulting in emaciation, anemia, stunted growth and development, weight loss, reduced meat, milk, and cashmere production, reduced fecundity, and reduced quality of cowhide due to maggot perforation. When the disease is severe, the cattle may even die. According to statistics, the meat production of adult yaks suffering from cowhide myiasis has decreased by 10% to 15%, resulting in an average weight loss of 20 kg per head, an average decrease in milk production of 20%, and a decrease in the grade of 70% of the cowhide, and even listed as the first class. Foreign products, lower disease resistance and easy to be infected with other diseases, a large number of calf yaks died. There are about 13 million yaks in my country, accounting for 92.08% of the total 14 million yaks in the world. Calculated according to the average parasitism rate of 84.25% of the cowhide fly, the annual average number of yaks in my country is 10.9525 million head, which brings huge economic losses to the yak industry. It is reported that Qinghai Province loses 10 million yuan of cattle annually due to yak cowhide myiasis, and Aba Prefecture and Ganzi Prefecture of Sichuan Province lose 4.5-5 million yuan and 1.5 million yuan of cattle annually respectively. Relevant experts estimate that my country loses 250 to 300 million yuan a year due to the disease, and the United States and the former Soviet Union lose 190 million U.S. dollars and 1.07 billion rubles each year.

Many countries in the world have conducted research on the prevention and treatment of this disease. The focus of the research is mainly on two ways of extermination in vitro and deworming in vivo. The former is represented by organophosphorus preparations and pyrethroids. In the 1990s, domestic pests were eliminated and insect killers were obtained, while abroad, eprinomectin was used. When yaks are infected with worms, the traditional methods of internal deworming are adopted, including oral or injection of deworming drugs and subcutaneous embedding of deworming drugs to allow them to be released slowly. This passive control method brings greater harm. First, the current deworming drugs are generally organophosphorus and organochlorobenzene preparations, which have relatively large side effects on cattle; increase, and transfer to the human body through the product, causing harm to the human body; third, injection and embedding of anthelmintic drugs may also cause discomfort in the body of the cow and infection and suppuration of the cow skin due to trauma; fourth, yaks are wild, and large-scale deworming operations Difficult, more labor-intensive, and easy to cause accidents in life. Therefore, there is an urgent need to study new drugs and new methods for preventing and controlling psoriasis in production.

In the grazing process of cattle and sheep, especially yaks with a relatively long growth cycle, individual identification of livestock is required from the perspective of grazing management and veterinary medicine. Herdsmen often use ear tags for cattle, but ear tags are more troublesome. and less significant.

In view of the above shortcomings of the prior art, the purpose of the present invention is to design a novel harmful flying insect repelling device, using suitable repelling agents and suitable methods, so that the medicines with repelling effect can be dispersed in a slow-release manner to repel mosquitoes. Fly and cowfly etc. leave the carcass.

The purpose of the present invention is also to implement the avoiding device together with individual livestock identification, so as to avoid the trouble of making another ear tag and improve the significance of individual identification.

The object of the present invention is achieved by the following means.

The cattle, sheep, mosquitoes and flies slow-release repellent pendant, which is used to hang on open livestock such as cattle and sheep to avoid harmful flying insects such as cowhide flies, has:

a) The repellent hanging ornament is composed of a repellant storage box and a livestock hanging mechanism;

b) The repellant storage box is equipped with a corresponding mechanism to facilitate the placement of individual livestock markings.

c) The repellant is a DETA amide compound treated with slow release, preferably an insect pheromone: N, N-diethyl-m-methylbenzamide.

After adopting the scheme of the present invention, the repellent with good effect on mosquitoes and psoriasis is screened out, and after slow-release treatment, it is supplemented with solidified materials to mix and mold, and it is attached to cattle and sheep to allow the drug to be released slowly and drive away the insects. Mosquitoes and cowflies leave the carcass, thereby preventing mosquitoes from harassing, blocking cowflies from producing maggots on the cow body, destroying the life cycle, achieving the purpose of prevention and control, and harmless to the cow body and the environment. Since individual livestock can be marked prominently on the hanging ornament, the multi-purpose effect of one thing can be achieved.

The accompanying drawings are as follows:

Fig. 1 is an appearance diagram of the hanging type cattle, sheep, mosquitoes and flies slow-release repellent hanging ornament of the present invention.

Fig. 2 is a sectional view of the repellant storage box of the embodiment in Fig. 1 .

Below, the technical solutions of the present invention will be further described in detail in conjunction with the drawings and embodiments.

Example

The avoidance hanging decoration is composed of a repellent storage box 1 and a livestock strap 2. The repellent storage box is provided with a corresponding mechanism for placing individual livestock labels. In this example, the mechanism for placing individual livestock labels is a storage box. The outer box plate 3 can have a larger selection range for the individual marks, and the corresponding individual mark storage mechanism adopts different corresponding structures according to the different styles of the cards. Such as the individual labeling adopts a card, and a transparent card holder is correspondingly set on the outer box plate of the storage box. Certainly also can adopt more convenient mode, such as in the present embodiment, directly be painted on the outer box board 3 of storage box exactly with marking paint. The repellant is DETA amide compound treated with slow release, and in this example, insect pheromone: N, N-diethyl-m-toluamide. The specific method is to use acetone as a solvent to condense insect pheromones into granules, and then use an appropriate amount of polyimine to form a slow-release coating on the surface of the granules, and then solidify the coated granules in a form. Filler support carrier 5. Forming fillers can be silica gel, diatomaceous earth, colloidal sand molding soil, etc. Finally, put the molded repellent into the repellent storage box.

In actual manufacture, repellants can be selected from other substances similar to DEET, such as DEET (N, N-E diethyl m-methylbenzamide), DEPA (N, N-diethylphenylacetamide), DM ( Dimethyl phthalate), MSC (methyl salicylate), BBZ (benzyl benzoate), etc.

The sustained-release agent can also use other substances with similar effects, such as polyvinyl chloride, polyisocyanate, polyurea, or some biological glues, such as gelatin, gum arabic, and trisodium alginate.

The hanging mechanism of the avoidance pendant can adopt a variety of forms, such as collars and the like.
