Prevention and treatment of cow mildew straw forage poisoning

During the wheat harvest and autumn harvest season, some parts of the rural areas are always overcast and rainy. When farmers are busy rushing to harvest grain crops such as wheat, corn and rice, they tend to neglect the collection and storage of crop stalks, so that the crop stalks used for feeding suffer differently. Due to excessive rainwater soaking, due to excessive humidity during the storage and storage of straw forage, some crop straw forage has mildew in different degrees. Cattle farmers who do not pay attention to the selection and collection of crop straw forage such as wheat straw, corn stalks and rice straw to feed the cattle can easily lead to cattle poisoning. Cow mildew straw forage poisoning is a type of cattle that eats moldy and deteriorating straw forage. The fungus, aflatoxin and other toxins in the cows cause swelling and swelling of the feet and legs of the affected cow, and even the hoof shells fall off. Toxic diseases. Generally, the occurrence of the disease has obvious seasonality. Generally, from October, when cattle start to eat straw forage, individual cattle will have the disease. From November to March of the following year, it will reach the peak of the disease, entering 4-5. Months later, as the cattle's intake of straw gradually decreased, the disease stopped on its own. Generally, buffaloes are common, and the disease is more serious and the course of the disease is longer. The incidence of cattle is relatively low, even if the symptoms are mild, the course of the disease is also short.

The disease often presents a sudden onset. When feeding cattle, observe that the feeding and drinking of the cattle are normal. When feeding the cattle and drinking water the next morning, it is found that some cattle have stiff gait, difficulty in movement, and Lifting the affected limbs intermittently, especially when the affected cow is towed to walk on a hard road, the lameness is aggravated, and the hoof of the sick cow is slightly swollen, and there is a feeling of fever, and the skin of the hoof crown and dentition appears rampant. Fissures, painful to touch; a few days after the onset, the swelling will spread to the wrist joints or tarsal joints, the lameness of the sick cow is obviously aggravated, the skin of the affected area becomes cold, and there is a light yellow transparent liquid exuding; then the affected area is covered with hair and swells. The skin is broken, bleeding, purulent, necrosis, sore face does not heal after long-term treatment, fishy smell is unpleasant, severe cases even cause hoof box or finger (toe) joints to fall off, and most sick cattle are often accompanied by different degrees of ear tip and tail necrosis, even There is a symptom of shedding. Yellow cattle generally have milder symptoms, but the disease in the affected area is not as obvious as that of buffalo, and the course of the disease is shorter, and the cure rate is generally higher, while the symptoms of buffalo are more severe, and the course of the disease can be more than one month or even several months. Sick cows often lie on the ground due to swollen hoof crowns and dents, and then develop bedsores, and eventually die or are forced to eliminate due to extreme exhaustion. Cattle farmers should effectively prevent the cows from being poisoned by moldy straw forage during the winter and spring house feeding period. During the wheat harvest and autumn harvest seasons, special attention should be paid to preventing rainwater from being exposed to the straw forage that is to be used for feeding. Straw forages that have been drenched in rain should be dried and air-dried when the sun is full, and the sun-dried and air-dried straw forages should be stacked indoors and stored in a dry place to minimize the use of mildewed straw forages. Feeding cattle; for straw forage that has been mildly mildewed, it can be placed in the sun and repeatedly beaten to remove the mildew, then cut or crushed, and the straw forage is ammoniated or micro-stored If you feed the cattle again, you can also add a comprehensive mycotoxin adsorbent and treatment agent (such as the mold is over) in the straw forage that is fed to the cattle to facilitate the adsorption of mycotoxins and Aspergillus flavus in the straw forage. A variety of toxins such as toxins reduce the probability of bovine mycotoxin poisoning and mycotoxins causing other diseases in cattle. For large-scale cattle farms, a mycotoxin treatment agent can be added to the straw forage from October to December and January to April of the following year to prevent mycotoxins and aflatoxins from harming cattle.

Once the cattle farmer finds that some cattle in the herd have symptoms of mildew straw forage poisoning, they should immediately stop feeding the moldy straw forage and change to other fresh forages. Pay attention to feeding the cattle with green and juicy forage And concentrated feed to strengthen the nutrition of the cattle, and take corresponding treatment measures of combination of Chinese and Western medicine in time for the sick cows: for the first-onset cows to promote the blood circulation of the affected limbs, hot compresses can be applied to the affected limbs of the sick cows. At the same time, 200-300 mL of white wine and 20-30 g of white pepper were used to give the sick cow a one-time oral administration, orally once a day, with continuous hot compress and internal medication for 2 to 3 days. If the part of the affected limb of the sick cow has been ruptured, the affected part should be treated effectively first. The coat of the affected part can be cut off, the dirt can be removed, and washed with 20% tannic acid solution or 30% boric acid solution. , And then apply 30% gentian violet or 30% silver nitrate solution to prevent the affected area and converge. In addition, take Jingfangbaidu powder orally to sick cows. The prescription composition of Jingfangbaidu powder is: 50 g each for Nepeta and Parsnip, 30 g each for Qianghuo, Dihuo, Bupleurum, Peucedanum, Citrus aurantium, and Platycodon grandiflorum, 25 g each for Ligusticum chuanxiong and Licorice, 40 g for Poria cocos, grind into fines, prepare with boiling water, and give after warming Cows are taken orally, 1 dose/d orally, and usually can be cured after 4 to 7 days of continuous treatment.
