What animals are pigs, horses, cattle and sheep?

Pig: Mammalia Artiodactyla Pigs are omnivorous meat livestock;

Horse: Mammalia Perissodactyla equine herbivorous livestock;

Bovine: Mammalia, Artiodactyla, Ruminata, Caveolidae, Bovinae;

Sheep: Mammalia, Artiodactyla). ruminants), Caveolae, Bovinae, Sheep. Capra.

What do pigs, horses, cows and sheep eat?

1. In addition to pig feed, pigs also like to eat grass is gray vegetables, chicken claw vegetables, wheel vegetables and pig sprouts. Also like to eat apples, potatoes are also pigs love to eat.

In addition to grass, hay, wheat straw and other coarse feed, the horse has to be fed concentrated feed, that is, beans, wheat and bran, so that it has the strength to do heavy work.

3, cattle are vegetarian animals, and a wide range of food, most like to eat grass, but also like to eat some green plants (or fruits), such as water peanuts, sweet potato vine (seedlings), corn (seedlings), rice, wheat seedlings and so on.

There are many types of grass that sheep eat, and the grass they like to eat can be divided into the following categories:

(1) by forage species

Sheep love to eat leguminous forage with high nutritional value, such as Chinese milk vetch, clover, clover, etc., do not like to eat straw, thatch, reed, etc.

(2) Divided according to the shape of forage grass

Sheep love to eat leaves wider and thin, not thorny grass, such as sweet potato leaves, mulberry leaves, etc., the leaves were pointed grass sheep do not like to eat, such as sand grass, rice grass, pine needle leaves, etc.

(3) Divided according to forage growth period

Sheep like to eat green grass in early flowering, do not like to eat old grass in late flowering.

(4) Divided according to the growing position of forage grass

Sheep like to eat the upper part of forage grass, especially the upper part with seeds. Don't like to eat coarse old grass near the root.

In winter when grass is scarce, sheep can eat hay. Hay can also be used as forage for rainy days. The method of making hay is to choose a sunny day, cut the grass and spread it out in the sun, and often turn it over. Generally, it can be dried after 2-3 days. Sun-dried grass should be tied into bales and stacked in high dry places, covered with straw to prevent rain from making hay moldy.

What are the differences in digestive physiology among pigs, horses, cattle and sheep?

1. Digestive physiological characteristics of pigs: Pigs are monogastric omnivorous livestock with underdeveloped caecum and limited digestive tract capacity. Food digestion depends mainly on chemical digestion, while microbial digestion is relatively small. Therefore, it is more appropriate to feed pigs with appropriate concentrate than with large amounts of green roughage.

2. Digestive physiological characteristics of horses: horses have small stomach capacity, long intestinal tract and large volume, especially developed cecum and colon. The caecum capacity of horses can reach 37 liters, accounting for about 16% of the total capacity of the digestive tract. There are a large number of microorganisms in the caecum, and its function is similar to the rumen of ruminant livestock.

3. Digestive physiological characteristics of cattle and sheep: cattle and sheep have four stomachs, which are rumen, reticulum, lap stomach and abomasum respectively. The first three stomachs are collectively referred to as the forestomach. They do not secrete gastric juice. Only the abomasum has gastric glands to secrete gastric juice. Its digestion mainly depends on microbial activities. These microorganisms (bacteria, ciliates and fungi) decompose cellulose in feed step by step to form acetic acid, propionic acid, butyric acid and other lower volatile fatty acids. Cellulose decomposed by forestomach can provide 60%-70% of the energy required by the body. Microorganisms can also use non-protein nitrogen-containing substances in feed to synthesize bacterial protein, enter abomasum, digest and decompose into amino acids through gastrointestinal tract, and absorb and utilize them into blood night.
