How to buy purebred high-yielding cows
The milk production performance of dairy cows is related to dairy cow breeds, feeding management, milking technology, climate, and other factors. The milk production performance of dairy cows needs to be observed and measured under certain feeding and management conditions, such as on-site determination of milk production and milk fats. Rate and so on. In fact, the production performance of dairy cows has a very close relationship with the appearance. Dairy cows with different production performances have unique appearance characteristics. Therefore, people usually identify the performance of dairy cows through appearance identification. Although this is not accurate on the spot, it is also a convenient method to quickly determine the performance of dairy cows. 1 Principle 1.1 of purchasing dairy cows. Buy cows in the affected area and avoid introducing any infectious diseases. 1.2 According to the physiological stage of dairy cows, priority is given to the purchase of bred cows, young cows and calves, and adult cows are not purchased as much as possible. 1.3 Buy cattle from the entire farm as much as possible to avoid scattered purchases. 2 appearance characteristics of adult high-producing dairy cows Most adult high-producing cows have thin skin, fine bones, short and fine coat hair, blood vessels exposed, underdeveloped muscles, moderate subcutaneous fat deposition, delicate appearance, detailed and compact body and other features, is a detailed compact Constitution type. The coat is black-and-white in color, with clear patches of flowers, white seals on the head, and two-thirds below the joints of the extremities and under the tail. The typical Chinese Holstein cows have white flowers on the shoulders and waist. Because the cow's head, neck, chest, and anterior chest are less developed than the hindquarters and the middle torso, the profile of the lateral, frontal, and dorsal view tend to be wedge-shaped. Slim limbs, thin skin, underdeveloped subcutaneous fat, short and dense hair, and thus the body joints are obvious, often can see the blood vessels and tendons bulge subcutaneously. The body's skeleton is compact, well-connected and gives a feeling of stretch. The head is slightly lighter and longer, the forehead is flat, the outline is clear, the skin is thin, the hair is thin, short and dense, and the head is light and handsome. The neck is slender, thin and soft, with capillary, short, and dense, forming a tight and neat skin fold. The width and depth of the chest is moderate, and the chest is not full. The previous squat distance is 37cm, and the chest depth is mid to upper, and the body height is about 55%. The ribs are long and sloping, the rib arches bend well, the intercostal distance is wide, and the distance between the last two ribs is more than 5cm. The chest skin is thin, subcutaneous fat is underdeveloped, and 2 to 3 rib arches can be seen from the side and the muscle development is moderate. The rib arches, muscle bundles and tendons can be clearly seen when inhaling. The back is long and straight, moderate and narrow, without subcutaneous fat, and the back spinous process is looming. The waist angle is wide, and it forms a horizontal line with the back and the chin, and the lumbar transverse process is obvious. It does not show the complex back and the complex back. The abdomen is stout, plump, well-developed, does not sag, and is significantly better developed than the chest, and the hernia is not obvious. The width, length, flatness and squareness of the ankle are 50cm in width and 53cm in length. The ankle angle is about 2 and the width of the ischial width is 2/3 of the waist angle. The limbs are upright, the joints are obvious, the length is moderate, and the limbs are strong. After the palate is wide, the muscles of the thigh are not full, the thighs are thin, and the mammography and the abdomen are high. The appearance of the breast is "bath-like", with large, deep breasts and flat bottoms, no less than the hocks. The front breasts extended downwards and attached well. The rear breasts extended to the top of the stocks. The attachment points were high, and the breasts were wide. There were obvious vertical grooves in the left and right breast milk sections. The four milk areas developed well-proportioned, and the nipples were evenly distributed. The shape of the nipples was cylindrical, 8-12 cm long, 3 to 5 cm in diameter, and the volume was more than 20 mL. The sphincter of the teat was normal. The skin of the breast is thin, and the hair is thin, short and thin. The subcutaneous fat is underdeveloped, and the swelling of the subcutaneous milk vein and the lateral suspensory ligament tendon can be seen during the prosperous period. From the internal structure of the mammary gland, glandular tissue should account for 75% to 80%, connective tissue and adipose tissue accounting for 20% to 25%, the so-called glandular breast. The breasts are full, bulky and elastic before milking, and the breasts are reduced in size after the milking, the hand feels soft, and many folds are formed on the back of the breast. The milk veins are thick, obvious, curved, and have many branches, and they cross into a network, and the milk wells are large. 3 Common appearance defects of dairy cows When a good-quality, high-yield cow is found to be defective, it must be included in different treatment levels depending on the site and its performance. There are two types of grades: one is shortcomings, three are serious, moderate and minor; the other is unqualified, which is a serious defect, especially genetic defects. The severity of the defects in each site can be determined by referring to the following criteria: Monocular hernia, unilateral or bilateral swelling is mild, turbidity is moderate to severe, and blindness is unqualified. The head is short, wide, and heavy are moderately flawed, and the forehead protrusion on the head is unacceptable. Tail root combined with lead, thick, short tail, skew or abnormal function (can not swing) is a mild to severe shortcomings. Permanent limb paralysis and poor function should be eliminated. Temporarily does not affect the normal function of mild defects, significant forelimbs are severe shortcomings, obvious hydrocephalus (swollen) is a slight disadvantage. Outside the hoof is a slight disadvantage. The low and high heights in front of the ankle were moderate to severe. There are no obvious demarcation lines between the right and left sides of the breasts. They are mild to severe defects. The weak breast attachments are mild to moderate defects. The breast attachment defects are serious defects. The milk leakage phenomenon (1 or more sides) is a slight disadvantage. The breast has induration. The clogging of the nipples is moderate to severe, and the unevenness of the four breast areas is called mild to moderate. The nipples are too small, too large, the shape is abnormal to mild to moderate defects, and the milk is abnormal (the blood in the milk has, Clots or water samples are classified as mild to moderate according to their degree, and breast milk areas are unqualified. Too small is moderate to severe. Cows are moderately to severely fat, and being too thin is a minor drawback. There are obvious traces of disguise, such as staining, modified teeth, etc., as unacceptable. Fri Martin's disease (abnormal genitalia, extremely short labia, tight contractions) was unacceptable. Temporary mild injuries, but not affect lactation, reproduction, etc., are mildly disadvantaged. The coat is dry, dull, and the nose is dry. Excessive weight loss is a serious defect to failure. Hanging on the abdomen, not full, is a moderate to severe shortcomings. The uneven back and upward bulge are serious disadvantages. Excessively dry or lean stools are moderately disadvantaged. Reproductive system diseases (including metritis, fallopian tube obstruction, ovarian atrophy, etc.) are generally moderately deficient to substandard. Ages above 10 years old are mild to moderate shortcomings. 4 Other Precautions 4.1 When purchasing cows in other places, it is necessary to know in advance whether or not there is an outbreak in the place of production, and make a quarantine inspection. 4.2 Pay attention to whether the conditions such as temperature, climate and forage quality in the production area are compatible with the place of purchase. 4.3 Do a good job of safe transportation. First of all, the vehicles that transported the herds were cleaned and disinfected. The height of the code trough was not less than 1.5m. Before the cattle were loaded, the vehicle was filled with soil or a mixture of fine ash and soil to prevent the cattle from slipping. According to the physical size of the cow and the physiological stage of separation, such as breeding cows and young cows installed in the rear of the car, pregnant cows and calves loaded in the middle or front. When the transportation time exceeds 6 hours, drinking water is needed on the way. When the dairy cows are transported for more than 24 hours, they are to be milked and rested. The cows are not allowed to rest on their way to prevent them being trampled by other cows. Transportation in the winter is selected in the afternoon and summer transportation is carried out in the morning and evening to prevent cows from being stimulated by hot and cold stress. The speed of transportation is kept below 40km, avoiding sudden braking, sharp turns, and sudden shifts causing cattle to abortion due to collisions and stress. 4.4 Newly purchased cattle are required to perform isolation observation and forage material transition. Newly requisitioned cattle should be housed in the isolation room under the windward direction of the cattle farm, or be observed in the woods to perform forage conversion. If you had previously grazing cattle, you would also have to deworm it. It takes about 1 week or more for isolation observation and forage material transition, during which quarantine and immunization are carried out. Rough feeds were fed on a regular basis, adequate water was supplied, and returned to normal cowhouses without any abnormalities. Gradually feed until the normal amount is fed.
