The influence of heavy rain in South China on pig breeding and how to deodorize pig farms.

1. Long-term heavy rainfall may cause floods, resulting in the destruction of pigsty and the drowning or washing away of pigs. 2. After the flood, the environment in the pigsty is too humid, which is conducive to the rapid propagation of germs and the breeding of mosquitoes and flies. There are a lot of pathogenic bacteria in the dead pigs. If not treated in time, germs will spread with air and water, leading to a large-scale outbreak of infectious diseases. 3. After the flood, inconvenient transportation will increase the death probability of big pigs during transportation. 4. The feed is moldy.

First, the impact of heavy rain in the south on pig raising.

1. Long-term heavy rainfall may cause floods, resulting in the destruction of pigsty and a large number of pigs being drowned or washed away.

2. After the flood, a large number of pigs fell ill and died, and there were a lot of pathogenic bacteria in their bodies. If not treated in time, they will rot and stink, and bacteria will spread with air and water, leading to a large-scale outbreak of infectious diseases.

3. After the flood, the environment in the pigsty is too humid, which is conducive to the rapid propagation of germs and the breeding of mosquitoes and flies, thus leading to a large-scale outbreak of infectious diseases.

4. After the flood, inconvenient transportation will increase the death probability of pigs during transportation, thus affecting the market price of pigs.

5, after the flood, a lot of feed in the water moldy, can no longer be used for feeding.

6. Under the condition of high humidity, it will cause stress in pigs.

Second, how to deodorize pig farms

1, intelligent feeding and deodorization

(1) Adding enzyme inhibitors to pig feed can reduce the ammonia content in the air by 50% and the hydrogen sulfide content by 18%.

(2) Adjusting the crude protein content in pig feed to about 10% and adding proper amount of tryptophan and lysine can reduce the emission of ammonia nitrogen, thus reducing the odor of pigsty.

2. Physical deodorization

(1) Putting proper amount of charcoal, activated carbon, cinder and quicklime in the pigsty can effectively absorb the odor in the air.

(2) Use dry, soft and clean padding, such as straw and sawdust (hygroscopicity is 400%, ammonia absorption is 0.6%).

3, Chinese herbal medicine deodorization

(1) Mixing Folium Artemisiae Argyi, Rhizoma Atractylodis, Folium Isatidis or garlic straw in a proper proportion and igniting can remove the odor in the air and play a role in sterilization.

(2) Feeding Chinese herbal medicines for clearing away heat and toxic materials can reduce the discharge of bacteria and ammonia nitrogen in the gastrointestinal tract, thus reducing the odor of pigsty.

4. Chemical deodorization

Collecting pig manure together and sprinkling appropriate amount of ferrous sulfate can inhibit the fermentation and decomposition of manure and reduce the odor. In addition, hydrogen peroxide, potassium permanganate, copper sulfate and acetic acid can also inhibit odor.

5, management technology

(1) Clean up the pigsty manure in time.

(2) Strengthen the ventilation of pigsty, and discharge the peculiar smell of pigsty as soon as possible.
