Characteristics of digestive organs in pigs
The teeth of pigs are developed, and the stomach is an intermediate type between the simple stomach of carnivores and the complex stomach of ruminants. The intestines are long, and various animals, plants and mineral feeds can be used. It should be noted that the digestion of crude fiber in pig feed almost depends on microbial decomposition in large intestine, so the digestibility of pig feed with more crude fiber is poor, and with the increase of crude fiber content in diet, the digestibility of pig feed also decreases.
Pigs are fast-growing and prolific animals
The rapid growth, multiple births and high yield of pigs require that a large amount of nutrients must be given in a short time to meet their needs, so pigs can digest a large amount of feed. Generally speaking, concentrate accounts for a large proportion in a day, that is, a large number of grains and their by-products need to be fed. These kinds of feed have more nutrients per unit volume, which is not easy to balance, that is, it is prone to some nutritional deficiency. When the amount of feed is insufficient or some nutrients are lacking, the adverse effects on pigs are rapid and significant. This requires that the pig's feed should not only be sufficient, but also be matched with a variety of feeds.
Smell and taste characteristics of pigs
Pigs are more sensitive to smell and taste than cattle and horses. They don't eat all kinds of feed, are selective, can distinguish tastes, and especially like sweets. Pigs like sweet potatoes best, but they don't like radishes. I like to eat the soft parts of Chinese cabbage, Chinese cabbage and green wheat, but I don't want to eat feed rich in crude fiber, such as green corn.
Pigs' preference for feed
Compared with powder, pigs like to eat granular feed, dry feed and wet feed, and pigs like to eat wet feed. For pigs, clinker is palatable, but it is not better digested than raw feed, which is both economical and beneficial.
