What to Do When Pigs Bite Each Other? 10 Solutions to Teach You

AbstractFirst of all, reduce the stocking density and raise pigs in separate pens according to body size; reasonably adjust feed nutrition by adding some fishmeal or soybean meal; increase ventilation to ensure air circulation; during the breeding period, take cooling and shading measures; bitten pigs should be isolated promptly and injected with antibiotics to prevent infection; piglets need to have their tails docked and teeth clipped in time; tires can be placed in the pen to divert the pigs' attention; a butter and Sophora flavescens liniment can be applied to the ear roots of both the biting pigs and the bitten pigs in the same group, and sick pigs should be isolated.

1. Reduce the stocking density

1. First of all, reduce the stocking density. It is generally recommended to allow 0.3-0.35 sq m per nursery pig; 0.5-0.55 sq m per pig weighing 20-50 kg; 0.6 sq m per pig weighing 50-70 kg; and 1 sq m per pig weighing 70-100 kg.

2. At the same time, raise pigs in separate pens according to body size, generally divided into three pen types: large, medium and small.

2. Reasonably adjust feed nutrition

During the breeding process, provide sufficient feed and water to avoid hunger and thirst in the pig herd. Pig biting may also be caused by a protein deficiency, so some fishmeal or soybean meal can usually be added to the feed.

3. Ensure air circulation

At the same time, prevent the pig herd from catching cold. The pig house should also be ventilated frequently to ensure air circulation, and feeding management should be strengthened to improve the pigs' disease resistance.

4. Keep warm

When winter arrives, take good warmth measures for the pig house. If conditions permit, a plastic warm shed can also be installed. The pig house must not have excessively high humidity, otherwise the pig herd may get sick from the cold and damp. In summer, take good cooling measures.

5. Shade the light

Also avoid excessively strong light. If the light is too strong, appropriately use a shade net to block it. At the same time, the lighting in the pig house can also be adjusted slightly darker, generally as long as it does not affect feeding. In the pig pen, a motorcycle tire can be hung with a rope for the pigs to bite.

6. Inject antibiotics

During the breeding process, bitten pigs should be isolated promptly to avoid being bitten to death. During this period, antibiotics can be injected to prevent infection. Pen sanitation should also be well maintained, which helps improve pig farming profits.

7. Spray to interfere with the pig herd's sense of smell

You can also mix floral water with water at 1:50 and spray it on the biting pen to interfere with the pig herd's sense of smell. The pig pen needs frequent changing and bedding. Around the pen, lime water, plant ash water, caustic soda water, etc. can commonly be used for disinfection.

8. Isolate aggressive pigs in time

1. During this period, the pig herd can be raised separately. At the same time, piglets need to have their tails docked and teeth clipped in time to reduce the occurrence of biting, and also to avoid the pig herd being injured too severely.

2. Also place some toys in the pen. Interesting toys can be hung on ropes or iron chains, or tires can be placed to divert the pigs' attention.

9. Apply butter and Sophora flavescens liniment

1. A butter and Sophora flavescens liniment can be appropriately applied to prevent pigs from biting each other. The formula is 1 kg of butter (bearing lubricating oil) plus 100 g of Sophora flavescens, then mixed evenly. Sophora flavescens has the effects of killing insects, killing fungi and relieving itching.

2. Butter has an unpleasant smell. Applying this formula to the ear edges and ear roots of both the biting pigs and the bitten pigs in the same group, as well as to the tails, can effectively stop biting, ear biting and tail biting.

3. If the density of the same pig group is too high, the pigs can generally be appropriately dispersed to reduce the stocking density. If it is due to a deficiency of certain nutrients, appropriately increase the feeding of complete-price feed.

10. Isolate sick pigs

If new pigs need to be placed in the pig pen for rearing, first place the new pigs alone in a separate pig pen. Wait until they have all adapted to each other's smell, then they can be raised together. When pigs are found to be sick, the sick pigs need to be isolated.
