The mini locking system can be used for the fixation of ossicles and small bone fragments, osteotomy, arthrodesis, and replantation and reconstruction of ossicles and small bone fragments.
It is composed of micro locking plate 1.5mm/2.0mm/2.4mm/2.7mm series, covering a variety of plate types and a wide range of indications. The plates are all anatomical design, which reduces the need for shaping and helps to reduce the workload of surgeons. Low profile and countersunk screw design can reduce soft tissue injury. Matching orthopedic screws self-tapping design, convenient implantation, screw plum design, reduce screw hexagonal sliding teeth. The composite hole design can not only realize the compression of the fracture end, but also can be used as a locking internal orthopedic fixation frame. Part of the reconstruction structure is convenient for the surgeon to tailor the implant according to the actual situation in the reoperation, and increase the flexibility of the operation. Its indications are mainly phalanx, metacarpal, scaphoid and other carpal bones, ulnar styloid process and capitulum, radial head and styloid process fracture fixation. The 1.5mm orthopedic implants titanium system is mainly used for the middle and proximal phalanx, the 2.0mm orthopedic plates system for the metacarpal bones, the 2.4mm implant locking plate system for the first metacarpal bones and carpal bones, and the 2.7mm mini plate system is mainly used for the distal ulna and radius. According to the clinical research, the micro-locking plate internal fixation in the treatment of multiple comminuted metacarpal fractures can effectively achieve the anatomical reduction and healing required by the clinic. The patients have good postoperative healing, and the functional recovery of the affected limb is good during the postoperative follow-up. It has good clinical effect and can be further promoted and applied.

Feeding of male cashmere goats
The reproductive efficiency of cashmere goats and the survival rate of their lambs are crucial factors in driving the development of the cashmere goat breeding industry. Therefore, proper feeding and management of breeding ewes play a vital role in ensuring successful outcomes.
Before breeding, it is essential to prepare the ewes by improving their body condition and providing adequate nutrition. The diet should support normal metabolic functions. After weaning, ewes that are underweight should receive additional nutrients to regain their strength. Typically, the daily feed consists mainly of dry roughage such as sweet potato vines and peanut stalks, which should be available for free grazing for about 4 hours each day. In addition, each meal should include 0.4 kg of mixed concentrate to meet energy and nutrient requirements.
During pregnancy, the nutritional needs of the ewe change significantly. In the first three months, the fetus grows slowly, and the nutritional requirements remain similar to those during the non-pregnant period. However, in the second half of the pregnancy, the fetus develops rapidly, with approximately 80% of its body weight gained during this time. Therefore, the ewe should receive high-quality, full-nutrient feed. The metabolic level should increase by 15%-20%, and calcium and phosphorus levels should be boosted by 40%-50%. Sufficient vitamin A and D should also be provided. Daily, 0.6-0.8 kg of mixed concentrate is recommended, and about 10 days before birth, juicy feeds should be introduced to support the final stages of fetal growth. Good management practices are also important—avoid overcrowding and sudden disturbances. Ewes should be kept in a calm environment, and they must not consume moldy or frozen feed to reduce the risk of abortion.
Lactation feeding typically lasts 2-3 months after kidding. During the first two months, milk production is critical for the lambs’ growth, so the ewe’s nutrient intake must be carefully managed. It is generally recommended that each ewe receives 1-2 kg of succulent feed and 0.6-1.0 kg of mixed concentrate daily. When nursing, the amount of fine feed should be controlled to avoid overfeeding, especially within the first 1-3 days postpartum, when ewes should avoid cold water and excessive soft feed. As lambs begin to eat solid food before weaning, the quantity of succulent feed and concentrate should be gradually reduced to prevent mastitis. The living area of the ewe should be kept clean and disinfected regularly, and waste materials like placenta and hairballs should be removed promptly to prevent lambs from ingesting harmful substances. Lambs are usually weaned around 2 months of age, depending on their growth and health status.
