Content of dry solid, protein, fat and calcium are much higher than cow milk, but it’s production is lower, most of greed has a milking production 5L/d, good breed can average reach to 8-10L/d. Buffalo are mainly in south China, can be fully used.

Milking camel can be separated to 3000L/y high production camel and 1500-3000L/y medium production camel and low production camel which is lower than 1500L/y. Only high and medium camel can be used as milking camel.

Though camel’s production is lower than holstein, but in the dry area, camel is the main source of milk. These years, the researcher find in camel milk, there exists functional proteins and peptides.

Because the content and form of lactose, protein are nearly like human milk in horse milk, it’s low sensitivity, high digestibility, so in past, horse milk usually be used for feeding baby instead of human milk. But in horse milk, fat content is low, fatty acid form is different from human. Because of the low content of casein in horse milk and the high PH, the milk can’t be curded, so it can’t be made to cheese. Horse milk can also be produced to horse milk wine, ethanol content is 0.6-3%, average 2%. In Europe, horse milk sometimes be made to cosmetic, like face cream, soap, moisturizing cream, etc.
