1, choose a good variety
When dairy cows are raised, high-generation black-and-white cows with higher milk production should be the first choice, and the daily average fresh milk production should be above 20?.
2, choose age and parity
When purchasing cows, the cow's age (or parity) is an important factor affecting milk production. The golden age of milk production for dairy cows is between 5 and 8 years old. Under normal circumstances, the first and second child will have low milk production. Later, as the number of births increases, the amount of milk production continues to rise and the 4th to 6th children are maintained at a high level. Later it gradually declined. Therefore, to enable cows to exert their higher production performance as soon as possible, cows aged 3 to 4 years or who have had 1 to 2 births should be selected.

3 Select a typical physical appearance
The quintessence of excellent dairy cows should be compact and compact. It requires strong physique, well-proportioned structure, shiny coat, thin skin and elasticity, fine and solid bones, moderate body length and depth, flat back, long buttocks, and well-developed chest. The abdomen was large without sagging. The body was observed to be "inverted triangle" from the top, side, and back. The black-and-white flowers were obvious. The three-section flower and saddle flower were the best. The limbs are strong and upright, and the gait and hoof shape of the cow must be carefully observed. The abnormally hoofed cattle often have limb and foot disease. For cows housed in pen homes, limb and foot disease is very prone to occur and will directly affect the milk production performance and high yield period of the cows.
4 choose to have a developed breast
It is the most important functional body type feature. The base of the breast should be extended and extended, and it should be well attached. The four breast regions should be well-proportioned, and the rear region should be high and wide. The nipples are vertically cylindrical and well spaced and symmetrical. Touching the breast with your hands is good and there is no abnormality. Before the milking, the milk well was obvious, the breasts swelled, the breasts became smaller after milking, and the back of the breasts had obvious wrinkles. The milk veins should be thick and curved, the bladder hairs are sparse, and the skin elasticity is good. This is the basic characteristic of a high-yielding dairy cow.
5 When choosing a cow
In addition to observing the appearance of the body, the calf's breasts, nipples, genitalia, etc. must be carefully examined. Whether it is a heterosexual twin or not, the opposite sex cow has no reproductive ability and must not be bought.
