Poor preservation of grasses often causes mildew and spoilage, especially during the summer and autumn. When the grasshoppers encounter a lot of fungus, the center and bottom of the grasshoppers often grow a large number of fungi. When cattle eat this part of the forage, poisoning symptoms will occur. The fungi that cause bovine poisoning are mainly Fusarium toxins. Fusarium can be parasitized on rice straw, wheat straw, sweet potato vines, peanut pods, and many pastures.
Diseased cattle show that mycotoxins mainly act on the peripheral blood vessels of livestock, causing local vascular spasmodic contraction, resulting in thickening of the wall, narrow lumen, causing slow blood flow and thrombosis, edema, bleeding and muscle deformation, necrosis, if Subsequent bacterial infections can further worsen the condition and severely rot below the ball joints. The disease often occurs suddenly and the gait is stiff. If you look closely, you will find that the hoof crown is slightly swollen. There is a horizontal crack in the skin of the recess, which is slightly hot and painful. After a few days, the swollen area will spread to the wrist or ankle and it will be difficult to walk. Afterwards, the skin of the swollen part became cooler and the surface appeared yellowish transparent liquid. If it continues to develop, it will cause bleeding, suppuration, and necrosis after swelling of the skin at the site of swelling. The wound will not heal for a long time and the odor will be unpleasant. Seriously, hoof can fall off. In some diseased cows, dry necrosis occurs at the tip and tail tip, and the skin is hard and dark.
Control Measures 1. When taking the grass at the bottom of the grasshopper, it is necessary to pay attention to the inspection. It is found that the grass that has become rotten and caked should be discarded as soon as possible.
Second, pay attention to the observation of cattle, found that cattle have limbs and foot lesions, they should be carefully examined, if determined to belong to mold herb poisoning, should be fed high-quality hay, while feeding germination feed, cabbage, radish, carrots, etc., to supplement vitamins Increase appetite.
Third, timely treatment of sick cattle. In the early stage of disease, in order to promote blood circulation, heat should be applied to the affected limbs, apply 2 to 3 times a day for 30 minutes each time, and mix white capsicum of 20 to 30 grams with 200 to 300 milliliters of white wine once before filling. For skin ulceration, the 0.1% benzalkonium bromide solution should be promptly used to clean the wound, and then the topical sulfa drug should be scattered, and antibiotics can also be used for treatment. In order to promote granulation tissue and epithelial hyperplasia and accelerate sore mouth healing, erythromycin ointment can be applied to the affected area 1 or 2 times a day. For serious conditions, intravenous injection of 5% glucose solution 1000 to 2000 ml.
