Pigs have long hair because of the following reasons:

1. The temperature is low, and pigs naturally have long hair.

2. The environment is uncomfortable, dirty and messy. When people are upset, their beards can grow by 1 mm overnight.

3. Environmental stress can also cause hair disorder. Such as noise, power failure, water shortage and so on.

countermeasures: give pigs a warm and comfortable environment and a good mood, and their hair will not be so long.

Extended information:

Pig hair length should also be properly supplemented with nutrition:

1. Pay attention to vitamin supplementation. The safety and balance of minerals and trace elements, the raw materials of minerals and trace elements contain toxic heavy metals, which will affect the growth, metabolism and health of animals. In particular, the zinc-containing raw materials are accompanied by excessive cadmium, and when the cadmium content is high, it will cause anemia and hinder the growth of animals.

2. Zinc oxide used in weaned piglets will lead to hair length, and high copper will lead to hair bending.

3. The nutritional imbalance caused by minerals and trace elements (excess of calcium, phosphorus, sodium, chlorine, sulfur, magnesium, copper and iron), pay attention to the mutual balance between minerals and trace elements.

4. Hair length may be related to overall nutrition. Vitamins, trace elements, energy, amino acids, etc. will be difficult to solve unless the formula is comprehensively adjusted.
