Diseases of the cattle limbs are one of the main problems of modern livestock breeding complexes.

Diseases of the cattle limbs are one of the main problems of modern livestock breeding complexes. In the last decade, the increase in the number of digital dermatitis (hairy warts) diseases has been observed not only in the countries with free-stall housing (USA, Britain), but also in the areas where there is a large proportion of open grazing (Australia, South America, New Zealand) and in the coming years this problem will become one of the main ones (Veremey E.I., Rukol V.M., Stekolnikov B.S., 2013).

It is based on many reasons, among which we can identify the cause related to injuries of the hoof horn, and in particular of the corium - the claw horn growth zone. Thanks to many studies (Ermolaev V.A., Marin E.M., Idogov V.V., 2009), it has been established that the digital torus is very vulnerable after calving, when the cows lose weight and the digital torus thinning as a result of undernutrition increases the risk of injury. Bent limbs in case of rickets, avitaminosis, injuries and other pathological conditions leads to a shift in the point of support to one of the side walls of the hoof, as a result of which one edge grinds away faster and the other grows. Moreover, the claws touch each other when moving; and it results in cracks formation. The group of risk also includes the irreversible bone overproduction at the late stage of laminitis, which requires the earliest possible diagnosis. Development of digital and interdigital dermatitis requires effective monitoring and regular preventive and therapeutic measures. In fact, they should be for cows about the same as brushing teeth for humans - seven times a week, twice a day.

According to Rukol V.M. (2014), in Belarus, 70% of limb diseases are associated with feeding disorders. Lack of vitamin A, sulfur and zinc in feed, disrupts keratinization processes. It is important to balance the diet for protein and fat (Derkho M.A., Sotsky P.A., Kontsevaya S.Yu., 2013). There is also a breed addiction to the pathologies of claw horns of the cows. Thus, white-and-black cattle and Holstein cattle demonstrate a higher susceptibility, fewer cases of diseases is recorded in Simmentals and meat breeds. Comfort of cattle keeping is a special factor: length of the stall, clean floors, dry hoof horn, the use of foot baths, etc.

All of the above factors indicate that keeping cows in poor conditions, the late removal of manure, the increased humidity and the concentration of ammonia results in violations of the hoof horn, its vulnerability to inflammatory and infectious diseases. When stalling animals, pelvic limbs are most susceptible when in case of short stalls, the hoofs are in the conveyor trough. A change in the limbs setting leads to deformation of the hoofs and frequent injuries. All this requires regular and optimum diagnosis and timely adjustment of hooves in cows in order to prevent the development of complications, often leading to culling. That is why the development of new methods of treatment and prevention is of high relevance.

Based on the restoration materials used in dentistry (Lyagina L.A., Galochkina L.L., Chuev V.P., 2006), we have developed and introduced into practice the “Bioinert glue for hooves” aimed at solving the task being important for veterinary orthopedics - treatment and prevention of hoof and claw horn injuries. This is a domestic innovative composite material that serves to quickly form an “artificial horseshoe”. Such glues are already actively used In agriculture in case of damage of the hooves of cows, goats, and sheep. This glue is based on ethyl methacrylate, while imported analogues (Germany) are made on the basis of methyl methacrylates, which require special storage conditions, accounting and reporting to national security, defence and law enforcement agencies, since ethyl methacrylate is not a precursor. This glue is in demand in agriculture in case of damage to the claw horn of cows, goats, sheep, pigs, as well as horse owners and cloven-hoofed animals in the zoos. The glue is non-toxic, does not cause allergic reactions, characterized by antiseptic properties. The indications for use of Bioinert glue for hooves are as follows: repair of cracks, correction of the shape of hoofs and deformations of claw horn in cattle and small cattlre fastening of horseshoes made of any material - metal, aluminum, wood, laminated fabric, plastics. We treated the cattle lameness under conditions of the dairy complex of Graivoronskaya Dairy Company LLC of the Graivoronsky District of the Belgorod Region. After the standard procedure of clearing and antiseptic hooves, a wooden block was attached to a healthy claw horn using a glue, which removed the load from the sick claw horn, thereby accelerating the healing process of the pathology. Bioinert glue for hooves was also used in the restoration of the hoof after such diseases as: laminitis, flat and convex claw horn. A minimum set of tools was used to apply this glue. The glue consists of two components and already after 1 minute after mixing, the glue is thick and acquires adhesive ability, after 3 minutes from the start of mixing, the adhesive ability disappears, after 4-5 minutes the mass hardens with the release of heat (60-70 °C), at the 8th minute it gains const hardness. The term of use of the mixture: 6-8 minutes. This time is sufficient to fix the orthopedic overlay, to form an “artificial sole” or repai the cracks and fissures.

Thus, the use of glue in the complex of preventive and therapeutic measures will help to solve the problem of reducing the diseases of limbs of animals, in complex conditions.
