What causes pigs to bite their ears and their tails?

Some pig farmers sometimes suddenly find that some pigs' ears are missing and some pigs' tails are missing. At this time, some pigs bite their ears and bite their tails because there is something wrong with the pigs. As long as we find the reason why pigs bite their ears and tails, we can stop the continued development of this phenomenon. So what is the cause of the pigs biting their ears and tails?

Pig herd

First, nutritional factors-when the various nutrients in the feed are not balanced, pigs will bite their ears and tails because of stress reaction. For example, the nutrition level of the feed fed to the pigs is lower than the feeding standard; the feed formula is unscientific, and the protein content in the feed in the early fattening period is low or the quality is not good; the lack of vitamins, magnesium, copper, iron, calcium and salt, as well as the lack of cellulose can cause pigs to bite their ears and tails.

Second, environmental factors-poor environment and poor sanitary conditions in the pig house, high concentration of harmful gases such as ammonia, carbon dioxide and hydrogen sulfide, too high or too low temperature, reduced ventilation speed or poor rest can lead to pig bites. In a harsh environment, stress also includes excessive light, and pigs can develop addiction due to excessive light.

Third, management factors-the density of pigs in the pigsty is too high, and pigs and pigs only fight each other for the position of feeding and drinking water. The weight of pigs in a pigsty varies greatly, and light and weak pigs are the targets to be bitten. Once bitten, all pigs will bite. Insufficient feed trough or insufficient water intake will often lead to the outbreak of pig tail bites.

Fourth, the cause of the disease-external parasites irritate pigs caused by skin irritation, friction on the walls and railings in the piggery, when there is trauma, other pigs will bite; when there are parasites such as Ascaris lumbricoides, there will also be the phenomenon of pigs biting their tails, so deworming should be done in time. The addiction of pig tail bite and ear bite can also be induced by pig anemia and tail tip necrosis.
