Detailed Explanation of Common Pond-Clearing Drug Types and Their Methods of Use
Drug-based pond clearing is the use of drugs to kill pathogens, parasites, and various predatory fish, wild trash fish, and other harmful organisms in the pond that endanger fish, shrimp, and crab fry, thereby preventing disease from affecting the normal growth and development of the cultured species and improving aquaculture efficiency. At present, there are many varieties of pond-clearing drugs, but different varieties have different effects. Commonly used pond-clearing drugs include quicklime, bleaching powder, tea seed cake, ammonia water, croton, Tangkening, and others. 1. Quicklime pond clearing Quicklime is calcium oxide.

Before feeding urea to cattle, first check the type of forage
When feeding urea to cattle, urea can be digested by microorganisms in the bovine rumen and synthesized into bacterial protein, replacing part of the protein feed, so urea is a high-quality protein supplement feed for cattle. But urea is not protein after all, and its utilization efficiency is affected by many conditions. Generally speaking, feeding urea to cattle should be determined according to the forage situation. In winter and spring, when the diet is mainly based on roughage such as wheat straw, dry corn stalks, and hay, urea can be added, while in summer and autumn, when the diet is mainly based on green forage, it should not be fed. Trials have shown that when the crude protein content in the feed is below 11%
