- Feeding behavior
Pig feeding behavior includes feeding and drinking and has various age characteristics.
- Arch soil characteristics
Pigs have the genetic characteristics of natural arches, and arching foraging is a prominent feature of pig feeding behavior. The pig’s nose is a highly developed organ, and the sense of smell plays a decisive role when the arch is foraging. Although in modern pig houses, pigs also exhibit the characteristics of arching foraging, each pig tries to occupy a favorable position of the trough when feeding, and sometimes the two forelimbs are placed in the trough for feeding, if the trough is easily accessible, Individual pigs even drilled into the trough and stood at the corner of the trough. Just like the wild boar arched for food, the kisses were arched along the trough, and the food was stirred up and thrown.
Pigs are particularly fond of sweets, and studies have found that unfed newborn piglets love sweets. Compared with the powder material, the pig loves to eat the pellets; compared with the wet material, the pig loves to eat the wet material and spends less time.
Group-fed pigs eat much more, eat faster, and gain more weight than single-fed pigs. Pigs eat 6 to 8 times during the day, 1 to 3 times more than at night, each feeding lasts for 10 to 20 minutes, and when feeding is less than 10 minutes, they are served (free feeding), not only for a long time but also for a long time. Can express the hobby and personality of each pig. The number of sucking of piglets every day and night varies with age, about 15 to 25 times, accounting for 10% to 20% of the total time of day and night. The feed intake and feeding frequency of large pigs increase with weight.
In most cases, drinking water is taken at the same time as eating. The amount of water in pigs is quite large. Piglets need water after they are born, mainly from the water in breast milk. The amount of water in piglets when eating is about twice that of dry materials, that is, the ratio of water to the material is 2:1; adult pigs In addition to the feed composition, the amount of drinking water depends largely on the ambient temperature. Pigs that eat mixed materials, drink 9 to 10 times a day, eat an average of 2 to 3 times of wet materials, pigs who eat dry materials need water every time they eat, and pigs that eat freely eat and drink alternately with water. Carry on until the satisfaction, limit the feeding pigs to drink water after eating. Piglets before the age of the month can learn to use automatic drinking fountains for drinking water.
In China, there are many cartoons based on pigs, such as “Little Pig Pecs” and “Pig Pig Man”. Pigs are also in the form of plush toys, which are more popular among children.
