Living habits and behavior characteristics of pigs

Pigs are omnivorous mammals, with fat bodies, short limbs, long nose and muzzle, short body fat limbs, gentle sex, strong adaptability, fast reproduction, black, white, red sauce, black and white flowers and other colors. Today, the editor of Qiannong Network will take you to take a look at the living habits and behavior characteristics of pigs.

Feeding behavior of pigs

The outstanding characteristics of the feeding behavior of pigs, when feeding, pigs try to occupy a favorable position in the trough, sometimes the forelimbs into the trough, so the trough should be blocked. Pigs feed freely, 6-8 times during the day and 4-6 times at night, each for 10-20 minutes. Pig feeding is competitive, group feeding is faster than single-feeding pigs, eat more and gain faster, and the feed intake of pigs increases with the increase of body weight. the feed intake of growing pigs is generally 3.5%-4.5% of body weight. The piglets who ate dry food drank 9 times of water every day and night, and ate an average of 2 times and 3 times of wet food. pigs who ate dry food drank immediately after each meal, and pigs who ate at random usually drank food and water alternately. When feed restriction, pigs drank water only after eating all the food.

And pigs are omnivorous animals, the type of pig stomach with large food intake is between the simple stomach of carnivores and the complex stomach of ruminants, the feed is widely used and diverse, and there are no microorganisms in the stomach that decompose crude fiber, so the content of crude fiber in pig feed should not be too high. When feeding pigs with green roughage, we should pay attention to the preparation of a certain amount of concentrate.

Pigs are also used to eating in arch soil, because the structure of the pig nose is suitable for digging, and the tip of the nose can be dug for food from about a week after birth. This is the nature of pigs, so the bed of the pig house must always be kept clean and dry so as not to cause dysentery.

Thermal regulation habits of pigs

The optimum temperature for growing and finishing pigs is 2024 ℃. The optimum temperature for piglets was 22-32 ℃. When the ambient temperature is not suitable, pigs show thermal regulation behavior to adapt to the ambient temperature.

When the ambient temperature is too high, pigs will consciously beat Wang in feces and urine or wet places. in order to dissipate heat, they will lie down with their limbs open, fully stretch their bodies, breathe faster or gasp for breath.

When the temperature is too low, the pig curls up to minimize exposure to the body surface. When standing, it shows tail clamping, curved back, tight arms and legs, and compact posture when eating.

Excretion behavior of pigs

Pigs like cleaning, pigs have the habit of defecating in low wet places, sleep in high dry places, and often keep clean. Therefore, the buildings of pig houses should be able to use their indignation to keep them dry and clean. Pigs do not defecate in the place where they eat and sleep, and show a certain rule of fecal excretion. Growing pigs generally do not defecate during feeding, and begin to defecate once or twice about 5 minutes after satiety, mostly defecating first and then urinating. It is easy to defecate before feeding, mostly to urinate first and then defecate. Only urinate and rarely defecate between two feeds. Defecation is usually carried out two or three times at night. Pigs are also used to excreting when they just get up to drink or get up and lie down. When the pigsty is too small, the pig density is too high, and the ambient temperature is too low, its excretion habits are easy to be disturbed and destroyed.

The gregarious nature of pigs

Pigs are timid animals who like to live in groups. Pigs of the same nest or different nests of the same size should be kept in the same pig house. Accustomed to group activities, living and sleeping, pairing is a prominent communicative activity, in which individuals in the group show physical contact and auditory information transmission, can live in harmony with each other, but also have competitive habits, big bullying, strong bullying, the larger the group, the more obvious this phenomenon is. Those who live alone may suspect that there is something wrong with them.

Pigs have a late and pure sense of color, but they are sensitive to smell, so corresponding measures should be taken in foster care. Pigs have a strong memory for eating and drinking, and it is easy to establish conditioned reflexes to the time, sound, smell and location of food trough related to eating and drinking. According to these characteristics, we can formulate the corresponding feeding management system, and carry out reasonable behavior training and training, such as regular feeding every day, training pigs to feed, sleeping, excretion triangulation and so on.

Pigs are a little neurotic and prone to stress caused by interference. So the breeders must take good care of the pigs.

The fighting behavior of pigs

Fighting behavior includes offensive, defensive, evasive and defensive activities. The fighting behavior seen in production is mainly for the fight for rank, territory and food within the group.

The exploratory behavior of pigs

Inquiry behavior includes exploration activities and physical examination behavior. Most of the general activities of pigs come from inquiry behavior, and most of them face the objects on the ground, through the senses such as seeing, listening, smelling, smelling, gnawing, arch and so on, in order to obtain the understanding and adaptation to the environment.

Abnormal behavior of pigs

Abnormal behavior refers to behavior that is beyond the normal range. It mainly refers to the abnormal behavior that causes harm to human beings and animals or brings economic losses, which is mostly related to harmful stimuli in the environment of pigs. These behaviors are mainly affected by the limitation of activities, long-term high-density captivity and other factors.
