Lime powder plays an important role in both pig and fish farming.

1、 In terms of pig farming

1. Disinfection and sterilization:

-Various bacteria, viruses, and parasites often exist in the pigsty environment, posing a threat to the health of pigs. Lime powder has a powerful bactericidal and disinfecting effect. Spraying lime powder on the floor, walls, and food troughs of pig pens can effectively kill various pathogens and reduce the risk of infection in pig herds. For example, during epidemics such as swine flu, using lime powder to thoroughly disinfect pigsties can reduce the spread of viruses.

-For newly built or thoroughly cleaned pigsties, using lime powder for disinfection can provide a clean and hygienic living environment for the pig herd. During the disinfection process, lime powder reacts with water to produce calcium hydroxide, releasing a large amount of heat. This high temperature also helps to kill bacteria and viruses.

2. Dry and moisture-proof:

-The high humidity in the pigsty can lead to the growth of bacteria and mold, affecting the health of pigs. Lime powder has strong hygroscopicity and can absorb moisture from the air, reducing the humidity in the pigsty. Keeping the pigsty dry can help reduce the occurrence of skin and respiratory diseases in pigs. For example, in humid seasons or regions, placing an appropriate amount of lime powder in the pigsty can effectively reduce humidity and improve the pigsty environment.

-When there is water accumulation on the ground of the pigsty, sprinkling a layer of lime powder can quickly absorb the moisture and dry the ground. At the same time, lime powder can prevent the ground from getting muddy, making it easier for pigs to move and clean.

3. Improve soil:

-For pig farms with outdoor activity areas, lime powder can be used to improve soil quality. Spraying an appropriate amount of lime powder into the soil can adjust the soil pH, neutralize acidic soil, and provide a more suitable activity site for pigs. In addition, lime powder can promote the growth of beneficial microorganisms in the soil and improve soil fertility.

2、 In terms of fish farming

1. Adjust water quality:

-The acidity and alkalinity of fish farming water bodies are crucial for the growth and health of fish. Lime powder can adjust the pH value of water to maintain it within a suitable range for fish growth. For example, for water bodies with strong acidity, adding an appropriate amount of lime powder can increase the pH value and improve water quality. Meanwhile, lime powder can also stabilize water quality, reduce pH fluctuations, and provide a stable living environment for fish.

-The calcium element in lime powder can supplement the calcium content in water and promote the bone growth and development of fish. For some fish that require a high calcium environment, such as shrimp, crabs, etc., adding a moderate amount of lime powder can meet their calcium needs.

2. Disinfection and sterilization:

-During the process of fish farming, various bacteria, viruses, and parasites can also exist in the water. Lime powder can disinfect fish farming water bodies and kill harmful microorganisms. Dissolving lime powder and evenly sprinkling it in the pond can effectively prevent the occurrence of fish diseases. For example, disinfecting the pond with lime powder before releasing fish fry can reduce the risk of fish fry contracting diseases.

-For ponds where fish diseases occur, using lime powder for disinfection can help control the condition and reduce losses. Meanwhile, lime powder can also remove algae and weeds from the pond, keeping the water clean.

3. Improve substrate quality:

-The silt at the bottom of the pond often accumulates a large amount of organic matter and harmful substances, such as ammonia nitrogen, hydrogen sulfide, etc., which can affect water quality and the health of fish. Lime powder can react with organic matter in sludge, promote the decomposition and oxidation of sludge, and reduce the production of harmful substances. Meanwhile, lime powder can also improve the aeration at the bottom of the pond, promote the growth of beneficial microorganisms, and enhance the fertility of the sediment.
