The treatment plan for common diseases of dairy cows - hoof diseases

1. Foot disease

It can be divided into saprophytic, interphalangeal dermatitis, hoof ulcer, horseshoe horny erosion, horseshoe thinning, white line abscess, etc.

Footrot disease (or interphalangeal cellulitis):
The identification of this disease is relatively simple, caused by the mixed infection of Nectobacillus and Pseudomonas melanogenesis, also, there are other important bacteria cell is Provera, the foot appears symmetrical swelling, dairy cows show claudication. It is usually caused by the injury of the interphalangeal skin, acute, sudden onset, acute disseminated inflammation of the interphalangeal skin and subcutaneous tissue, and often affects the hoof crown, the diffusion swelling of the system and the bulbous segment, the local heat pain is obvious, the waveform is obvious, often accompanied by the joint movement restriction, and often forms one to several suppurative fistula.

Intramuscular injection of cefotaxime sodium or intramuscular injection of 50ml once. The patients with high body temperature were mentally poor combined with flunixin meglumine.

Local treatment:
Cattle farmers should press to check the bottom of the hoof for obvious pain points, where there is an obvious pain point and the horseshoe horniness becomes soft and discoloration, should repair the hoofs. First disinfect the bottom of hoof with 5% iodine tincture, dig the discoloration and soften place of a horseshoe with a disinfected hoof knife, when reaching the hoofed dermis, drain out stench suppurative exudate, rinse with hydrogen peroxide normal saline to wash the pure fish stone fat bandage of tocopherol powder.

If there is a pyogenic focus, rinse and remove the necrotic tissue and fill in the purulent cavity with the thick juice mildew powder defatted cotton, and change the medicine once every two days. At the same time, penicillin sodium 4 million units, 0.5% procaine hydrochloric acid 30 ≤ 40 ml, in the swelling part 3-4 points of muscle injection slightly above, once a day, for 5 days.

2. Interphalangeal Dermatitis:

Interphalangeal Dermatitis mostly occurs in a wet environment. According to the painless decay or ulcer of the interphalangeal skin, the bacterial infection of diseased cattle with less obvious symptoms was judged. Hoofs are often moist and secrete white exudates with specific odors, which is different from hoof rot. This will lead to skin hyperplasia and interphalangeal fibroma. Open the toe space so that the cow can wash and expose the damage to the air.

If the infection extends to the heel, the protease produced by Pseudomonas Aeruginosa can digest the keratin in the hoof tissue, corrode the keratin layer of the heel to varying degrees, or cause the transverse rupture of the junction between the heel and the bottom of the hoof, when the heel breaks and the skin of the ampulla ensues During excessive proliferation, claudication caused by interphalangeal inflammation increases the load-bearing pressure on the heel of the hoof. Interphalangeal dermatitis usually occurs symmetrically on both limbs.

Main symptoms:
Inflammatory exudation, swelling, pain, further extension of corrosion enclave, resulting in horny decay, cracking and so on.

Treatment: first, dairy farmers should check the sick dairy cattle, then the whole hoof was cleaned with clean water or 0.1% Xinjielmil disinfectant, and the overgrowing cuticular layer and suppurate between toes were repaired. Sterilize the toes with 5% iodine tincture, apply a piece of skim cotton and fish fat, copper sulfate to the toes, wrap them with bandages, and remove the bandages a week later. When dealing with the fracture of the heel, the flap on the surface of the cuticular layer should be removed and the closed part should be exposed to the air.

3. Hoof inflammation:

This disease used to be called Hairy hoof warts, strawberry hoofs, verrucous dermatitis, interphalangeal papilloma, in fact, it is still a kind of interphalangeal dermatitis. The local redness of the intersecting toe seam of the soles of the foot can be used as the initial lesion of interphalangeal dermatitis-strawberry Interdactyritis. The most significant characteristic of the injury is the degree of pain in dairy cows, the formation of tongue protrusions in the gap between the two fingers (toes), the continuous thickening, the extension between the toes and the heel, and the surface infected by the friction and breakage of the ground. It seriously causes limp. Verrucous dermatitis is a disease caused by fungi. Long white hair grows between the hoofs, local skin inflammation exudates, and then occurs in the Between the two hoofs grow like strawberry accretion, local infection exudate is kerosene color, stench. The last two hoofs atrophied and the hoofs stood upright and severely limped.

For the small hyperplasia, potassium permanganate powder can be used to corrode, large value-added substances can be sterilized with 5% iodine tincture, then removed with sterilized scalpel, external application of turpentine oil, Bufao ointment (Yuanheng) or pure fish stone fat-free cotton hoofing bandage, and bandage removed a week later.

4. Horseshoe horny erosion:
The horniness at the bottom of the hoof or the heel of the hoof turns black, and the horny roots form a deep pit and gradually spread around, filling the soil with feces. But because it did not extend to the dermis, there was no obvious limp.

Cattle breeders should remove all rotting horniness at the bottom of the hoof with a hoofing knife or hoofing knife, thoroughly dig out the fill dirt, and make the rotting horseshoe form a fresh surface. Where horseshoe horniness has stratification, should remove the outer layer separated horniness.

5. Foot ulcer:

The horseshoe cutin erosion and spread to the hoof dermis, the diseased hoof dare not bear the load, limp shows moderate to severe claudication. When walking in the dairy farm, they gently load with the tip of the hoof or dare not bear the load.

Wash and sterilize hoofs with 0.1% Xinjielmil or 0.1% potassium permanganate, and disinfect hoof bottom of 5% iodine tincture. Remove rotting horniness from the bottom of the hoof with a hoof knife, and dig deep into the dermis of the bottom of the hoof. Fully remove inflammatory exudates from the true skin at the bottom of the hoof. Rinse the dermis infection part of the hoof bottom of hydrogen peroxide, rinse again with normal saline, sprinkle oxytetracycline powders / powdered at the skin of hoof bottom, apply turpentine oil, Buhoofeng ointment (Yuanheng ) or pure fish stone grease defatted cotton, hoof bandage. Replace the medicine and hoof bandages every 3 / 4 days.

6. The bottom of the hoof becomes thinner:

The horny of the horseshoe is overworn and the horny of the horseshoe becomes thinner; or when the horseshoe is immersed in feces and urine for a long time and the horseshoe cutin becomes soft, the cow causes contusion in the dermis of the hoof because of uneven ground, accidentally stepping on the stone on the ground or a hard protruding object. Moderate to severe claudication caused by exudation and congestion of the dermis at the bottom of the hoof.

Improve the environment, reduce the removal of footwear factors, pad the opposite side of the sick toes with wood blocks to protect the overworn bottom of the hoofs.

7. White line abscess:

A white line forms a white line between the stratum corneum and the stratum corneum which is the dividing line between the horseshoe cutin and the hoof dermis. When hoof protection is poor, white line split causes hoof dermis infection and shows moderate to severe claudication.

After binding the cow, washing the foot of diseased hoof with 0.1% potassium permanganate water. Sterilize the bottom of the hoof with a 5% iodine tincture. Dig the cuticular layer of the white line of the hoof with a disinfected hoof knife until the leather at the bottom of the hoof is revealed. The accumulation of inflammatory exudates in the dermis at the bottom of the hoof is excluded. Rinse with hydrogen peroxide and then with saline. Apply oxytetracycline powder, external application turpentine, or hoofing paste (Yuanheng) or pure fish grease defatted cotton, hoofed bandage.
