Buying cows is technically certain. Some cultivators do not know how to pick the cows and are often deceived. Some dairy cows purchased were not pure, and the milk production was very low; some purchased cows and eliminated cows and caused economic losses to themselves. To buy a good cow, identify from the following aspects: 1. Look at the appearance of the cow. The basic characteristics of high-quality dairy cows are: Black-and-white flowers in the whole body, and the boundaries of flowers are obvious. The skin is thin and thin, blood vessels are exposed, muscles are not developed, and there is less deposition of subcutaneous fat. The head is long and elegant, the neck is long and the chest is narrow, the chest and abdomen are wide and deep, and the hindquarters and the breast are well developed. The head and neck, the back thigh and other parts have obvious angular profiles. Looking from the side, looking ahead, looking up are all wedge-shaped. Look sideways: extend the top line forward, then connect the breast and the ventral line, extend it to the front of the cow, and intersect with the extension line of the top line to form a wedge shape. It can be seen that the cow's body is shallow and its hindquarters deep, indicating that the digestive system, reproductive organs, and lactation system are well developed and have a high milk yield. Forward look: From the top of the head, make a straight line extending below the left and right shoulders respectively, and the straight lines under the chest intersect to form a wedge. This wedge indicates that the scapular muscles are not much, the chest is wide, and the vital capacity is large. Look up: Two lines are drawn from the head to the left and right lumbar angles respectively, and they intersect with the lines of the two waist angles, which also form a wedge shape. This wedge indicates that the hindquarters are large and well developed. 2. Look at the cow's breasts and ankles. The breasts are well developed, basin-shaped or bowl-shaped, with smooth underside, large nipples, four nipples, moderate distances, multiple breast flexions, few breast hairs, good skin elasticity, and high milk production. The cow's crotch should be wide, long and flat, that is, the distance between the waist and the end of the ischium should be wide, and should be on a horizontal line. The distance between the hip, waist, and ischium looks like an isosceles triangle. 3. See if the cow has a disease. When picking cows, pay special attention to whether there are diseases. Observe all the parts of the cow's body, watch the excrement, watch the food intake, etc., and must not purchase cows in the affected area. 4. Look at the ordained age of cows. In this face, technicians often look at the number of teeth and angles to determine the age of the cows. For those aged cows that are eliminated, they cannot afford to buy high milk production. 5. When purchasing heifers, in addition to observing the appearance of the body, the calf's breast bladder, nipple, and genitalia must be carefully examined. 6. To purchase a pregnant cow, check whether it is accurately conceived or not, and ask about milk production so as not to buy empty cows. Specifically, it can be summarized as: Oxtail should be fine, there is no neck bag, there must be a peak, the neck should be thin, and the head should be small. From the rear, look at the cow's vertical line, high hind legs, front legs, breasts and four flat heads. The breasts need to be full. There must be milk wells. There must be no well-developed muscles in the four structures. The fat is less, the coat color is distinct, and the black-and-white flowers are distinct. To relax (tight is not a cow), the gap between the ribs should be wide, to be able to insert two fingers, the gantry horns. China Agricultural Network Editor
