Corrective measures for abnormal behavior of captive pigs

With the development of the large-scale swine industry, the abnormal behavior of pigs has continued to rise, mainly due to biting tails, biting ears, and fighting between pigs and pigs. The disease is a common practice in many pig farms and is also known as embarrassment. Pigs that are bitten can cause wound infections if not treated promptly. This infection can cause local inflammation and tissue necrosis, severely affect the pig's health and growth performance, reduce carcass quality, and cause unnecessary economic losses.

A large number of experiments at home and abroad believe that the main reasons for the abnormal behaviors of captive pigs that induce or promote tail biting and ear bite include nutrition, environment, and management. This phenomenon is particularly prominent when seasons alternate and temperatures change drastically. Therefore, we must take targeted measures to correct it:

First, balanced nutrition

Nutrient imbalances in diets can induce abnormal behaviors. For example: When the protein content in the diet is low, the protein metabolism of the pig body will be disordered and will show some abnormal behaviors, including excitement and biting; when the mineral elements such as iron, copper, calcium, magnesium and salt are lack or proportion in the diet. Inadvertently, abnormal performance such as convulsions, intolerance to stress, and increased excitability of neuromuscular can occur. It also promotes mutual biting and fighting. Vitamins are an important component of many metabolic enzymes in the body. When there is a lack of vitamins, the body will Metabolic disorders can occur, causing abnormal behavior.

Second, optimize the environment

Environmental factors mainly include harmful gases, temperature, and light intensity. For example, when the environmental sanitation conditions in the pig house are poor and the ventilation effect is poor, accumulation of harmful gases such as ammonia, carbon dioxide, and hydrogen sulfide in the house can cause irritation in the pigs. These stress factors can stimulate tail biting. occur. The high temperature and high humidity in the pig house can easily cause pruritus on the pig's body and can also induce mutual bites. In harsh environments, noise, strong light and other factors can promote stress response and increase fighting in pigs.

Third, strengthen management

If the rearing density is too large, the pigsty space is too narrow, and the pigs come in contact with each other to clash. They compete for positions of eating and drinking and bite each other. After the group is swarmed, the pigs need to be familiar with the troughs, sinks, and rings. Planting facilities and establishing order of gregariousness, pigs usually perform very lively and often fight. In particular, pigs with small weight are often the object of being bitten.
