Breeding of hybrid goats

The Bor crossbred sheep, which is obtained by crossing Boer goats with local goats, has good production performance. In order to give full play to its advantages, the following points should be mastered in management: Feed nutrients should appropriately increase the growth and development of hybrid sheep, especially in the 6 to 9 months after birth, and the body weight can be doubled compared to the local sheep. The demand is also relatively high. It is necessary to properly supplement the local sheep's diet. Hybrid sheep born in spring are generally not allowed to feed at the other places except where the forage resources are properly supplemented before and after weaning and before going on the market. In the autumn, the hybrid sheep born in the autumn are generally fed supplements, otherwise the hybrid sheep will be affected in the early growth and development, and the feeding effect will be poor. Strengthen management In addition to doing a good job of day-to-day management, we must timely castrate and periodically deworm. Lambs are usually cast off about two months after birth. In the spring and autumn, each flukes and nematodes were driven once every two months to drive the locust once every two months. The ectoparasites were driven once in spring, autumn and winter. Short-term fattening sheep were short-term fattened 1 month before slaughter. Under normal grazing conditions, hybrid sheep of about 6 months old were fed 150 grams of corn, 100 grams of bran, 50 grams of pods, and 3 grams of bone meal each day. After about 1 month of fattening, the hybrid sheep can gain 6-8 kg. Lambs listed on the first year of the hybrid sheep growth speed is particularly fast, generally 6 to 9 months of age can reach 25 to 30 kg. Even the hybrid sheep born in the fall can grow to 20 kilograms around 4 months of age as long as they strengthen nutrition and provide reasonable supplements. In addition, a reasonable arrangement of breeding time is also a measure to ensure that the lamb is listed in the same year.

Hip Joint

In hip joint replacement surgery, can be broadly divided into two kinds,cemented artificial hip and cementless artificial hip, due to the selection of different materials, the price is also very different.
Generally , the cemented type is suitable for osteoporosis, poor bone conditions, 65 to 70 years of age and older patients. The use of bone cement for artificial hip joints allows for early mobility, which is also suitable for older patients. In addition, elderly patients are generally less active, artificial joint wear is also light, replacement of an artificial joint can be, generally need less revision. The price of bone cement type artificial joint is low.
Cementless type is also known as biological fixation type, suitable for young and middle-aged patients with good bone conditions, such artificial joints have micropores or biological coating materials on the surface, bone can grow into it to achieve the role of fixing artificial joints, so it is often called biological fixation type. Cementless artificial hip joints allow their bones to slowly grow together with the artificial joint to achieve a fixed role.

Total cementless hip system indications

1.The main purpose of total hip replacement is to relieve hip pain,and the second is to improve hip function. The main indication for total hip arthroplasty is hip pain caused by hip lesion over 60 years old,which can not be used for other operations but only for head and neck resection.

2.Replacement surgery may be considered in patients over 45 years of age with subluxation of the hip,traumatic arthritis, pain, or loss of function.Due to the insufficient depth of the acetabulum,the upper margin of the acetabulum is inclined, which affects the stability of the acetabulum cup,and the acetabulum should be deepened or covered.

3.Indications of the need for replacement include hip pain due to loosening of the prosthesis,stem fracture,prosthesis dislocation, manual reduction failure,central dislocation caused by acetabulum wear caused by prosthesis and pain.
