Dairy cow stray feeding is different from conventional fixed house feeding. The basic feature is that the huge integrated cowshed is simplified into a clean and clean mechanized milking parlor. It will only be used within one to twenty minutes of each milking and feeding of concentrate feed. Dairy cattle are bred and rest for free. They are allowed to walk to a place with a feeding trough and a sink to feed on roughage, drink water, go to a place with a warm shed and free cattle bed, ruminate and rest, so as to keep the personnel in the integrated cow all day long. The operation of transporting grass, material, milk, and manure around the cows is simplified to allow the cows to milk, defecate, graze, and eat at their designated locations. This not only reduces labor, but also conforms to the ecological habits of dairy cows. It further meets the requirements of “the separation of people, cattle, and milk in the milk production process†stipulated in the modern food hygiene management law. In recent years, many areas have begun to explore this way of feeding, but the rearing of the stray bar is different from the traditional fencing system. The breeder must pay attention to the following issues. First, the overall layout of the cattle farm and barn design. The overall layout of the cattle farm is the use of various types of cowsheds, milking parlors, and feed areas for the acquisition, processing, storage, and supply of feeds. The location of snow, excreta treatment areas, other ancillary buildings, and their facilities are mutually exclusive. The connection should facilitate the most efficient and economical operation of dairy cows in the future, and strive to reduce the walking distance of dairy cows, shorten the distance between workers' operations and feed transportation, and avoid overlap and crossover of the manure and net roads, so as to facilitate health and epidemic prevention and reduce milk consumption. Pollution. Because the barn raised for the flocks is a place for the cows to eat, drink, rest, and move, the design must not only strive to be sanitary and comfortable, but also consider the convenience of the worker's operation, while also minimizing the cost. Second, business management. The biggest difference between the management of dairy farms and the dairy farms in the traditional sense is that the managers, technicians, and workers must have a modern consciousness. They must not only know how to raise cattle, they must also be familiar with mechanical operations, and then they must adopt strict labor. The combination and labor management mobilize the enthusiasm of all staff to achieve the expected business objectives. Third, feeding and management. Fence feeding is different from the traditional individual fine breeding for group difference breeding. A breeder usually manages more cows than ever before. The grouping and grouping of cows becomes an extremely important link. Developmental cows should be rationally grouped and timely mobilized for first-born cows, dry cows and breast-feeding cows (including cows at the end of lactation, late-lactation cows) and at different stages of growth. Before the grouping, it is necessary to do the basic work such as the cow's milk yield determination and body condition assessment. The group size should be compatible with the cowshed structure and milking equipment. Leg-and-feet disease is usually one of the main diseases for feeding studs to cows, because cows have more opportunities to walk in this feeding situation, and their hoof soaks excrement for a long time. According to the experience of some large studded dairy farms, soft and dry materials should be used to build cattle access and cattle beds. The treatment of excreta in the barn should be carried out 1 or 2 times a day depending on the situation. At the same time, the hoofs of the cows are regularly given a medicated bath, and the hoof shape is regularly refitted to treat the hoof disease in time. The author has seen a lot of dairy farms abroad to prevent hoof disease by using wood chips, rubber mats to pave the floor of the cowshed or implement leaky seam flooring. The cows do not have a fixed bed under flocks and are free to stay up all night. This poses great difficulties for the cow's estrus identification. Therefore, besides strengthening the sense of responsibility of staff and increasing the number of observations of estrus cows, production must introduce new technologies, new methods, etc. to help identify and correctly handle estrus cows. Computer surveillance tracking cameras are used abroad. Simultaneous estrus technology and placing bulls in herds. Fourth, supporting machinery and machinery management. Straw-feeding is a highly efficient and modern production method. Only a series of mechanical equipments can be used in dairy farms to maximize the efficiency of mechanized production. This is also an important guarantee for successful stray feeding. In some domestic dairy farms, the effect of stowing the stray feeders is not good and the machinery and equipment are not matched or the performance is not enough. It is not unreasonable to insist on using them for a long time. Although some dairy farms use imported machinery and equipment, it is also advisable to study the localization of machinery spare parts as soon as possible so as to avoid the use of spare parts. In addition, stray dairy farms should be equipped with mechanical management and maintenance personnel. According to experience, placing mechanical maintenance personnel on part-time jobs in each operation group will have better results than setting up a separate mechanical repair department. On the one hand, it will avoid operators' complete reliance on mechanical repairmen, and on the other hand, it will benefit the daily maintenance and repair of equipment.
Electric Wheelchair is an important Household Medical Equipment for the wounded, sick and disabled at home for rehabilitation, turnaround transportation, medical treatment, and outings. The Wheelchair not only meets the needs of the physically disabled and the disabled, but more importantly, it is convenient for family members to move and take care of them. Patients, so that patients with the help of wheelchairs for physical exercise and participation in social activities.
Manual Hospital Wheelchair are generally composed of a foldable frame, front and rear wheels, left and right knee pads and footrests, left and right detachable armrests, handle brakes, seats, backrests with medical imaging data bags, bedpans, urine bag hooks, and electric standing. The hand-crank wheelchair adds a hand-crank device on the basis of the ordinary wheelchair. On the basis of ordinary wheelchairs, the electric wheelchair adds an electronic power assist system, which reduces the physical exertion of the user. Based on the electric wheelchair, the intelligent wheelchair adds positioning movement, standing movement, remote control movement and related Internet + assisted living.
