Duck feed preparation general principles

1. Ducks often eat fresh mollusks such as fish, shrimp and snails. These animals contain a substance called thiamine that can destroy vitamin B1, so ducks are prone to vitamin B1 deficiency. The disease occurs mostly in young ducklings and often occurs within 2 weeks of age. Therefore, in the case of ducks able to eat aquatic animals, it is necessary to increase the vitamin B1 content in the diet, especially in ducklings. 2. Vitamin D deficiency often occurs in laying ducks, which is caused by insufficient supply of vitamin D in the diet or insufficient exposure of the birds to sunlight. Diseased waterfowl showed poor growth and development, feathers were unorganized, dull, and production decreased. Shells and soft shells were produced, and eggshells were easily broken. Therefore, it is often necessary to additionally add cod liver oil or vitamin A, D3, E, etc. to the duck feed. 3. Ducks usually lay eggs in the early morning. Therefore, ducks must maintain high blood calcium concentrations in the early morning. Otherwise, they will produce sand shell eggs, misshapen eggs, and even reduce egg production. When preparing egg-laying duck feeds, it is necessary to have a fast-absorbing calcium source and a slowly-absorbing calcium source. Stone powder and shell powder are usually used as calcium sources at the same time. 4, feed ingredients and with a good feed should be stored in ventilated, dark, dry place, in order to avoid oxidation of fat in the feed, vitamin A, vitamin E were destroyed. Place a layer of moisture-proof material between the feed and the ground to prevent feed build-up and mildew. Moldy feed is prone to cause duck poisoning, pupa and so on. In addition, the feed store should pay attention to pest control and rodent damage.

Rib Plate

Rib Locking Plate System is suitable for the fixation of rib fractures,which includes rib locking plate,rib locking screw and rib plate.

Ribs are structures throughout the thoracic cavity that protect vital organs such as the lungs, heart, and liver.The human body has 12 symmetrical pairs of ribs.

Where did the fracture occur?

Rib fractures are more common in adults. Fractures of one or more ribs may occur, and multiple fractures of the same rib may occur. The first to third ribs are shorter, protected by the scapula, clavicle, and upper arm, and are generally less prone to injury, while the floating ribs are more elastic and less prone to fracture. Fractures usually occur in four to seven ribs.

What is the cause of the fracture?

1. Direct violence. Fractures occur where violence directly affects them. They are usually cross-sectional or comminuted. Fracture fragments are often displaced inward and easily penetrate into the lungs, causing pneumothorax and hemothorax.

2. Indirect violence, chest is squeezed back and forth, fractures often occur near the axillary midline. The end of the fracture protruded outwards, which easily punctured the skin and caused open fractures, such as collapse or improper exertion during external cardiac massage. There have also been cases of posterior rib fractures due to violent blows to the anterior chest, or anterior rib fractures due to blows to the posterior chest. Most of the fractures were oblique.

3. Mix violence and others.

What type does fracture have?

1. Simple fracture

2. Incomplete fracture: mostly crack or green branch fracture

3. Complete fracture: most of them are transverse, oblique or comminuted

4. Multiple fractures: one bone and two fractures, multiple rib fractures

5. Open fracture: mostly caused by indirect violence or firearm injury

What are the complications of sternal fracture?

1. Abnormal breathing 2. Pneumothorax 3. Hemothorax
