**Discussion on the New Type of "Power Planer" Hoofing Method**
Fang Guowei, Veterinary Officer, Beijing Sifang Animal Husbandry Company
Cow hoof disease, also known as "leg and foot disease," is one of the "three major diseases" that threaten dairy cows. Due to varying pasture conditions, the incidence rate of hoof disease ranges from 5% to 40%. This not only affects the daily life of dairy cows but can also lead to a decline in milk production. If left untreated, it may result in culling, causing significant economic losses. Approximately 15–50% of cattle culling is attributed to hoof diseases. Common types include hoof deformity, laminitis, foot rot, interdigital hyperplasia, hoof dermatitis, hoof erosion, and sole trauma. Among these, hoof deformity and foot rot are the most prevalent. Regular hoof trimming is an effective way to prevent hoof diseases and improve cow welfare. Traditionally, this was done using iron shovels or hoof knives, but now, the "electric planer" method has become a more advanced and efficient technique.
**Hoof Repair Equipment**
The specialized equipment includes a German-imported electric planer, commonly used for hoof trimming.
**Principle of Hoof Repair**
1. Hoof trimming is divided into two categories: maintenance and therapeutic. It should be done twice a year. Traditionally, trimming was performed during spring and autumn, but now some farms schedule it 3–6 weeks before calving and 120 days into lactation. Studies show this timing has minimal impact on milk yield. Combining both methods based on pasture conditions is recommended.
2. Maintenance trimming focuses on correcting toe length and angle, ensuring balance and even weight distribution between the toes. The hoof’s angle and curvature must be considered, with some stratum corneum retained. The hoof tip should be flat, slightly rounded at the front, and have a proper arc between the toes.
3. Therapeutic trimming involves treating injuries and providing systemic care based on the cow’s condition.
**Steps for Hoof Repair**
1. Prepare the holding frame, electric planer, power supply, ropes, and medications.
2. Place the cow in the restraint frame, secure the neck, and fasten the chest and abdominal straps. Ensure the cow is comfortable and avoid compressing the udder.
3. Secure the hind limb, lift it carefully, and adjust until the ankle and ischial regions align.
4. Clean the hoof with water and brush, inspect for cracks or lesions, and decide on the trimming plan. Avoid over-trimming unless necessary.
5. Use the electric planer to trim one toe at a time, ensuring stability and safety. Stop if the cow becomes agitated.
6. After trimming, use a hoof knife to clean between the toes, remove necrotic tissue, apply antiseptic, and bandage. For severe cases, trim healthy toes and treat the affected area.
7. Repeat the process for the front hooves, following the same procedure.
**Summary**
The electric planer method improves efficiency, is easy to operate, and requires moderate investment. It is highly recommended for widespread adoption. However, all farms should prioritize prevention and implement strict hygiene and management practices to reduce disease occurrence.
**Suggestions**
1. A balanced diet with appropriate calcium and phosphorus levels is essential. Imbalances can cause hoof problems, such as osteoporosis or keratinization issues. Vitamin D and trace elements are also crucial. A proper ratio of roughage to concentrate feed (e.g., 30:70) supports hoof health.
2. Maintain clean and dry environments to reduce hoof disease risk. Regular cleaning, disinfection, and hoof inspections are vital. Routine trimming and the use of formalin or copper sulfate solutions help control infections. Perform two annual hoof trims per cow.

Blood pressure reduction can be broadly divided into the following categories:
1. Diuretics:
Diuretics reduce blood volume by increasing the kidneys' excretion of sodium and water, thereby reducing the amount of fluid in the circulatory system. This helps reduce the pressure on the walls of blood vessels, resulting in lower blood pressure. Common diuretics include hydrochlorothiazide and indapamide. When using diuretics, it is necessary to be aware of possible side effects such as electrolyte disturbance.
2. Beta-blockers:
These drugs work by binding to the heart's beta receptors, reducing heart rate and myocardial contractility, and reducing cardiac output. At the same time, they also reduce sympathetic nerve activity, causing blood vessels to dilate, thereby lowering blood pressure. Common beta-blockers are metoprolol, bisoprolol, and so on. However, in some cases, such as patients with severe chronic obstructive pulmonary disease or asthma, it should be used with caution.
3. Calcium channel blockers:
Calcium channel blockers inhibit the contraction of vascular smooth muscle by preventing the influx of calcium ions in vascular smooth muscle cells, to dilate blood vessels and reduce peripheral vascular resistance, thereby reducing blood pressure. Nifedipine and amlodipine are common calcium channel blockers. They also have a certain dilating effect on coronary arteries and can improve blood supply to the heart muscle.
4. Angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor antagonists (ARBs) :
ACEI can inhibit the activity of angiotensin-converting enzyme and reduce the production of angiotensin II, thereby dilating blood vessels and lowering blood pressure. At the same time, they also have a certain protective effect on the heart and kidneys. Common ACEI are captopril, enalapril and so on.
ARBs play an antihypertensive role by blocking the binding of angiotensin II to receptors. This class of drugs has similar antihypertensive effects and organ protection to ACE but may be better tolerated in some patients. Common ARBs include valsartan, irbesartan and so on.
5. Alpha blockers:
Alpha-blockers work primarily by blocking alpha receptors on the smooth muscle of blood vessels, causing blood vessels to dilate and reducing peripheral resistance, thereby lowering blood pressure. This class of drugs is mainly used to treat high blood pressure caused by prostate hyperplasia but is relatively rarely used when used alone to lower blood pressure.
It should be noted that different types of blood pressure-lowering drugs have their specific indications and contraindications, and should be individually selected and adjusted according to the specific situation of the patient when using, while closely monitoring blood pressure changes and side effects of the drug.
