Recently, a friend who raised cattle left me a message backstage, wanting to know more about the dry goods of German hoof trimming. So I intensively collected information, and made a detailed arrangement from the symptoms and harm of bovine hoof disease, the classification of hoof repair, the standard of hoof repair, the tools of hoof repair and so on.
First, the symptoms of bovine hoof disease
With the growth of cattle, the cutin of hoof, toe and sole will also grow metabolically. Imagine what would happen if our nails were never cut? On the other hand, the same is true of cattle hooves. If it is not pruned in time for a long time, it will not only breed bacteria, but also affect the center of gravity of cattle. Small hooves can hardly bear the weight of more than 600kg, which may lead to hoof disease.
1. Bovine hoof disease initially manifested as pain, swelling, suppuration and ulcer in limbs and feet. With the aggravation of the disease, it will lead to anxiety in standing, difficulty in lying down and even difficulty in walking.
2. Without timely and effective treatment, the affected limb can't bear the weight, and the weight will be transferred to each limb to bear the weight alternately by adjusting the posture, thus causing one or more limbs to limp, kneel and have severe pain;
3. With the aggravation of lameness, the intake and milk yield of cattle decreased sharply, the production capacity was lost, and the hoof shell fell off, rotted and deformed.
Second, the harm of bovine hoof disease
Cow's hoof is as important to cattle as feet are to people. Generally speaking, the harm of bovine hoof disease mainly includes the following five aspects:
1, which affects the normal feeding and rest of cattle, and will lead to the slow growth rate of cattle and even negative weight gain;
2. Lactating cows will greatly affect milk production and increase the incidence of mastitis;
3. Secondary diseases such as bovine pasteurellosis and systemic septicemia will occur, which will lead to the death of cattle in severe cases;
4. Pregnant cows with upper limb hoof disease will increase the risk of miscarriage, and the abortion rate is 3~5 times that of normal cows, even if they don't have abortion, they are more likely to have dystocia.
5. Cattle will be eliminated in advance, and limb and hoof disease will greatly increase the elimination rate of cattle, directly affect the economic benefits of cattle farms and cause huge losses.
It is suggested that friends who raise cattle must pay attention to the harm of bovine hoof disease, pay attention to the health care of bovine limbs and hooves at ordinary times, and have the concept that prevention is greater than treatment. We can promote physical health from three latitudes: the enclosure environment of cattle hooves, the hygiene of cattle and the timely repair of hooves.
Third, functional and therapeutic hoof repair.
The purpose of hoof trimming is to make cattle walk comfortably. According to different uses, it can be generally divided into functional hoof repair and therapeutic hoof repair.
In German cattle farms, large-scale hoof trimming is generally organized twice a year in the spring and autumn. If the hoof is healthy, it can be functionally repaired. The cattle are driven into the vertical hoof repair vehicle, and the hoof repair engineer measures the size of the cow's hoof with a hoof repair caliper to determine the hoof repair scheme; Then use a hoof trimmer to cut off the hard cutin of the hoof toe, and use a hoof trimmer to cut off the extra cutin between the sole of the hoof and the toe seam; Then use a special angle grinder to polish the hooves more smoothly. After functional hoof trimming, cattle can move freely.
The actual situation is often more complicated. Cattle hoof with hoof-trimming disease should be treated on the basis of functional hoof-trimming. Under normal circumstances, if one of the inner and outer toes of a cow's hoof is good, the diseased hoof toe can be treated with drugs and bandaged, and then wooden shoes can be stuck on the healthy hoof toe with special glue for repairing the hoof, so that the wound can be suspended and ventilated to promote healing. Generally, the cow can walk normally after the wooden shoes are glued. If both toes of the hoof are sick, it is necessary to wrap the hoof as a whole and then fix it with a self-adhesive elastic bandage to prevent infection. Put the cows in the dry pen to rest for about four weeks, and at the same time reduce the amount of milking to promote recovery.
Four or six latitudes of hoof repair standards
After reading the above, some friends may be curious. What is the basis for German hoof trimmers to repair their hoofs? Through practice and experience accumulation, a quantifiable and unified hoof trimming standard for different breeds of dairy cows has been formed. Details are as follows:
1, and the included angle between the hoof bottom and the hoof wall should be between 45 and 50.
2. The size of hoof wall will vary according to the breed and growth stage of cattle. For example, the hoof wall size of Holstein cows is 7.5cm, and the hoof wall size of large cows is larger.
3. The toes should be 5cm thick.
4, hoof toe inside and outside the height should be consistent.
5. The height of both sides of the inner and outer toe grooves should be consistent.
6. In the third part of the hoof toe, the distance between the inner toe and the outer toe should be 5 mm wide.
Verb (abbreviation of verb) German hoof training school -Defi Woldegk
In Germany, a pedicure is a very tall and respected profession, and of course, the income of a pedicure is also very considerable.
-Defi Woldegk, a German school specializing in training hoof trimmers, has a history of more than 30 years. Because of its exquisite hoof trimming technology and the innovation and improvement of tools such as hoof trimmer, it has attracted many hoof trimmers and cattle breeders from other countries to study.
Defei Waldeck professional hoof repair company is a German enterprise in Sino-German animal husbandry cooperation project. According to the demand of Sino-German animal husbandry and cattle industry cooperation demonstration enterprises, we went to China for hoof trimming technical training.
Six, the choice of hoof repair tools
Germany is a pragmatic and innovative country. With this spirit, it has also been at the forefront of the world in animal husbandry and exported many advanced experiences.
In the aspect of hoof repair tools, Germany has been adhering to the consistent fine quality management, while maintaining the ingenious quality, and constantly exploring and innovating in continuous practice, and combining with the needs of hoof repair technicians, it has developed a series of highly comfortable and efficient hoof repair tools, which have made great achievements in hoof repair vehicles, hoof repair pliers, hoof repair knives, calipers, hoof repair glue, bandages, wooden shoes and so on.
Under the call of many cattle-raising friends-hoping to recommend some hoof-trimming tools with good performance and high cost performance, Mudao Tiancheng selected a batch of imported hoof-trimming tools from Germany through the professional recommendation of German animal husbandry experts and strict and meticulous screening, hoping to bring help to all animal husbandry friends.
