Domestic animals and poultry are two different types of animals that humans have domesticated and raised for different purposes. Their differences are mainly reflected in the following aspects:
Differences in classification: domestic animals belong to the class Mammals and are four-legged mammals, such as cattle, pigs, sheep, etc.; Whereas, poultry belongs to the class of birds and are birds that walk on two legs, such as chickens, ducks, geese, etc.
Appearance and physiological characteristics: domestic animals are usually larger than poultry, with four legs and well-developed muscles, and the body surface is covered with short hair; Poultry belong to the category of birds and are relatively small in size, have two legs, and are covered with feathers.
Mode of reproduction: domestic animals are viviparous, that is, the mother conceives her young until birth; Poultry are oviparous, such as eggs, duck eggs, goose eggs, etc., and the offspring need to hatch to hatch the birds.
There are some differences between the product forms of livestock and poultry:
1.*Meat products**: The meat of domestic animals is usually larger, such as beef, pork, mutton, etc.; Poultry meat is comparatively smaller, such as chicken, duck, etc.
2.*Eggs**: poultry eggs, such as eggs, duck eggs, etc., are usually oval in shape; Whereas, domestic animals generally do not lay eggs.
3.*Dairy products**: Livestock can provide dairy products, such as cow's milk, goat's milk, etc.; Poultry, on the other hand, does not produce dairy products.
4.*Fur products**: The fur of some domestic animals can be used to make clothing, leather goods, etc., such as sheepskin, cowhide, etc.; Poultry feathers are mainly used to fill pillows, make down products, etc.
5.*Other products**: Livestock can also provide other products, such as bezoar, bristles, etc.; Poultry may produce some special products, such as chicken manure that can be used as organic fertilizer.
These differences are mainly due to the different physiological characteristics and uses of livestock and poultry. Of course, the specific product form will also be affected by factors such as breed, feeding method and processing.
