Swine spring diarrhea is swine dysentery; early prevention and early treatment are key
Swine dysentery is an intestinal infectious disease caused by Brachyspira hyodysenteriae. It occurs mostly in growing pigs, with few cases in piglets and adult pigs. It spreads slowly, has a long epidemic period, a high incidence rate, and a low mortality rate, and can harm pig herds over the long term. Affected pigs pass feces mixed with large amounts of mucus and blood, often in a jelly-like form. Drug treatment for this disease is effective, but relapse is easy after withdrawal, making it difficult to cure completely. Drugs such as mequindox, berberine, bacitracin, olaquindox, and tetracycline can be selected for treatment. If the therapeutic effect is found to be poor, the drug should be switched as soon as possible.

How to prune goji berry in spring? Detailed methods and techniques
1. Thinning branches. First, cut off dead branches, diseased and pest-infested branches, damaged branches, thorn branches and crossing branches, then thin out overly dense fruiting branches.

Weeding and loosening the soil is generally carried out from the end of February to early March, with a depth of 10-15 cm. Applying bud-promoting fertilizer: The bud-promoting fertilizer should be applied early rather than late, with a trench opened 15-20 cm from the tea plant roots
