1. Shear wool is a major by-product of sheep, and every year during the spring months from May to June, it must be cut once. Fine-wool sheep and semi-fine wool sheep usually cut their hair once a year. The shag sheep can be cut twice a year. In addition to spring, they are cut again from September to October. The shearing of sheep is divided into mechanical shearing and manual shearing. Large-scale and intensified pastures usually use mechanical shearing, which is fast and saves time and labor; manual sheep shearing is still common in small-scale sheep farms. When using manual shearing, scissor, sharpening stone, mat, hemp rope, and iodine should be prepared before shearing. The breeding field must also be weighed and recorded. Fasting shears are safer. Shearing sheep does not grazing, feeding and drinking, and is usually performed in the morning. Choose to be sunny without wind. When shearing hair, first bind the left and right forelimbs of the sheep with a rope, so that the sheep is lying on the left side, and the shearing staff is squatting on the back of the sheep. The back ribs of the sheep are cut straight forward, and then the abdomen and chest are cut in parallel directions. The hair, then cut the front and rear legs, always cut the sheep's half hair. Use the same method to cut the other side of the hair. When cutting hair, the scissors should be laid flat and close to the sheep's skin so that the hairs stay short and neat. If the cut is not neat, do not cut it. The cut hairs should be together and become a complete set of hairs for easy grading. During the shearing process, care should be taken not to cut the skin. Once it is cut, it should be sterilized with iodine to prevent infection. 2. Cashmere cashmere is the main product of cashmere goats. Between April and April each year, it is the goat fleece season. Cashmere goat hair is divided into two layers of outer and inner hair. The outer coat is long and thick, called coarse hair, and has no economic value. The inner layer is velvety and soft, called fluff. Cashmere is a valuable worsted material. Cashmere goats are generally known as fleece and after shearing. In some places, to facilitate fleece, the outer hairs are cut off before the fleece is caught. However, fleece is again used. Whether or not the hair is cut after fleece depends on the situation. Different regions have different climatic conditions. The time of fleece is slightly different. Generally, the time mechanics of fleece from south to north or from plain to mountainous area is delayed. The same species of different genders had different velvet shedding time, and generally the ewes fell off earlier than the rams. In general, when the weather has warmed up in early April, the cashmere of cashmere goats gradually began to fall off. At this point, when the plucking hair is found to be removed from the skin, it is the appropriate time for fleece. When fleece is used, special wool fleece combs (a kind of combing and a combing) are used to fleece. The sheep that first wants to fleece are bundled up to shake off grass clippings, feces, and sandy soil on the sheep. Use combing hair to comb the sheep's neck, shoulders, chest, back, waist, and fat, and then grasp it again with a thick comb, and then grasp it again with a comb against the hair. When combing the fleece, it should be close to the skin and evenly pressed. The fluff off time is not the same in different parts of the same individual. In order to ensure that the fluff catch is clean and does not cause any loss, the fleece is usually caught again after the first fleece. To ensure the safety of fleece, fleece sheep should fast for more than 12 hours. Pay attention to the ewes during late pregnancy, so as to avoid excessive movement caused by miscarriage. Different cashmere colors have different economic values. Before fleece, the flock should be separated by the color of the fleece, usually divided into white, green and purple. After the sheep has sheared wool and fleece, a medicinal bath takes 7-10 days depending on the weather conditions. Breeding technology should vigorously develop the sheep-rearing industry. Breeding technology is one of the key links. Breeding is a necessary means to increase the number of herds and improve the quality of herds. In order to improve the breeding ability of sheep, it is necessary to grasp the breeding characteristics and laws of sheep and to understand the various internal and external factors that affect reproduction. In sheep production, breeding laws are applied and advanced breeding techniques are adopted so that the production of cultivated sheep can be carried out in a planned manner according to human requirements.
