Etiological diagnosis and analysis of pig bite rack

In the process of pig breeding, the phenomenon of pig bites (including tail biting) often occurs, especially the lean pigs which grow fast and can not keep up with feeding and management are more likely to occur, and the wound is inflamed and ulcerated, which affects the production of live pigs. caused a lot of economic losses. Here, briefly talk about the inducement of pig bites and solutions for reference.

1 the inducement of pig bites

1.1 when the feeding density is high (> 3 piglets / m2), the feeding trough is narrow, and the conflicts of contact with each other are frequent.

1.2 the single column feeding population is large (> 10 heads / column), and the individual difference is great.

1.3 pigs are not fed enough and feed is not enough; when drinking water is insufficient, pigs are thirsty.

1.4 A sudden entry into a strange pig herd, such as joining a herd or jumping into a pen.

1.5 short sleep and feeding time, long activity time, strong light and monotonous environment (all cement floors and walls).

1.6 the air of pig house is polluted, the temperature and humidity are high, the air flow is not smooth, the pig house is wet, and the feces are dirty.

One of the pigs in column 1.7 had extracorporeal trauma and bleeding or suffered from some physiological disease (such as sudden high temperature) and gave off a distinctive smell.

1.8 long-term addition of drugs, especially ethanol and dysentery (currently prohibited), is also one of the inducements.

1.9 the feed is moldy, spoiled, or not fresh.

1.10 it is caused by stress factors such as heredity, abrupt climate change or sudden refueling.

It can be seen from the above that in addition to the nutritional imbalance, the defect in feeding and management is the most important factor in the occurrence of bites in pigs.

(2) the key to prevent pig bites should start with management and do a good job in the following aspects:

2.1 severing of the tail (2 days after birth) is an important means to prevent the bite, of course, it is not to say that there is no bite after the breaking of the tail).

2.2 timely drive after the occurrence of the bite, it is really not good, the pig can only be moved to the empty circle.

2.3 improve pigsty environment, remove stress and strengthen feeding management.

2.4 put old tires (bicycle, motorcycle outer tire) in the column to distract the pig's attention and satisfy its playing nature.

2.5 Bite pigs can be rubbed with irritating potions (such as purple potions, etc.).

2.6 when merging groups or moving circles, first, it is best to choose at night, and second, it is best to spray alcohol.
