How to buy fattening cattle
As the saying goes, “Sheep quarry phaseâ€, therefore, to obtain a good fattening effect, choosing a cow with fattening potential is critical. I. Individual choice Hybrid improved bull is the main object of fattening, according to the local conditions, the market demand for beef grades, select the appropriate age and weight of the cattle, after slaughter in time for slaughter. Age identification When the age of the cow cannot be known exactly through the breeding archives, the age is the most accurate method based on teeth. 1 identification basis. It is mainly based on the regularity of the occurrence, removal and abrasion of the incisors. The general calf has been born with 1 to 2 pairs of mastoid teeth, 3 to 4 months of age incisors are fully developed, 4 to 5 months of age gradually wear the tooth surface, wear to a certain degree of breast teeth began to fall into permanent teeth. The order of replacement is from the jaws, and finally the tines. After the incisors are changed, they gradually wear out and fall off when they are very old. 2 The difference between milk teeth and permanent teeth. The milk teeth are small and white, with gaps between the teeth, the surface is flat, the teeth are thin and detailed, there are obvious teeth neck; the permanent teeth are relatively large and thick, the crowns are long and arranged neatly, there is no gap between the teeth, and the roots are brownish The tooth crown is yellowish. 3 methods of identification. The complete incisor replacement is called "Qikou", and generally the buffalo is about 6 years old and the cattle are 4.5 to 5 years old. The age of cattle after Qikou is mainly judged based on the abrasion condition of the permanent incisor tooth surface. 2. Weight measurement The body weight can be measured directly on the floor scale, or it can be measured with a ruler, and can be estimated by the following formula: 1 Cow or lean-in cow weight (kg) = [bath (m)] 2 body sloping (m) 90.2 beef cattle or meat Combined use of cattle weight (kg) = [bust (m)] 2 body length (m) 100.3 serving cattle weight (kg) = [bust (cm)] 2 body oblique length (cm) 10800. Bust is after the scapula The edge of body circumference. The oblique body length is the distance from the front edge of the shoulder end to the posterior edge of the ischial tuberosity, and the soft ruler should be close to the skin when measuring. The straight body length is the horizontal distance between the vertical line drawn from the front edge of the shoulder and the vertical line drawn downward from the posterior edge of the ischial tuberosity. Different ages of cattle fattening, feed compensation varies greatly, in production practice, to select 1 to 2 years old, weight 250 to 300 kilograms of cattle, fattening is the most economical. 3. Appearance selection According to experience, cattle with large fattening potential only have the following characteristics: mouth width, strong feeding ability, alignment of upper and lower lips, strong force, good tooth structure; loose skin, high elasticity; open meat area, large skeleton, back Waist length, width, chest depth, width, length, width, body; health, no digestive system disease. In addition, as a whole, the body shape presents a rectangular brick beef cattle with great fattening potential. For the lyrical cows, we must carefully understand the history of their feeding, only those who because of a lack of early stage feed lack of sensation, compensation when fattening effect is good, and indigestion cattle no fattening value. For cow's lyrical appraisal, firstly observe the size of the body of the cow, see the width and depth of the body, the state of the abdomen, the length and direction of the ribs, and then use the hand to detect the neck, lumbar, shoulders, back, waist, ribs, buttocks, ears, tail, Thickness of the scrotum and other parts of the meat layer, the accumulation of fat. Second, the price accounting The cost of cattle, in addition to the price of cattle itself, should include transaction fees, quarantine fees, exit fees, transportation costs, and transportation losses. Before the acquisition, it is necessary to understand and estimate each item, measure the cost of the fattening process, the cost after the slaughter, and the income after the sale of the product. The balance of payments should be known to determine the minimum price for purchasing the cow.
