Long-term feeding of sows with feeds containing carrots and vitamin A deficiency, hot weather causes oxidation of vitamins in sow feed, improper preparation of feed processing and improper storage methods, in addition to a significant decrease in sow resistance, newborn piglets due to breast milk Lack of vitamins, easy to suffer from vitamin A deficiency.
Symptoms: piglets with indigestion, diarrhea, diarrhea, dry skin, blindness, nervous disorders, difficulty walking on the limbs, secondary hepatitis, etc., can cause death in severe cases.
Prevention: Increase the amount of vitamin A in sow milk. The content of vitamin A in sow milk is closely related to the supply of carotene in the feed. The more carotene is supplied, the higher the vitamin A content in milk. Therefore, the lactating sow feed should be supplemented with a variety of vitamins rich in carotene and vitamin A, such as Jun Wei'an developed by Tengjun Pharmaceutical Co., Ltd. to increase the supply level of carotene in the feed and increase the vitamin in the sow milk. The content of A. In this way, not only can the prevention of vitamin A deficiency in piglets be effectively prevented, but also the growth and development of piglets is also very beneficial.
Treatment: piglets suffering from vitamin A deficiency, subcutaneously injected with 5-10 ml of refined cod liver oil per head; or 2.5-5 million international units of vitamin A injection, intramuscularly, once a day for 5-10 days; or Vitamin A, vitamin D injection, sows use 2-5 ml per head, piglets use 0.5-1 ml per head, intramuscular injection. Oral cod liver oil can also be taken internally. The sows use 10-20 ml each time, and the piglets use 2-3 ml each time, once a day for several days. In addition, symptomatic treatment of inflammation of the eyes, respiratory tract and digestive tract can be performed.
Ground Screw For Solar Power System
Ground Screw for solar power system is applied in fixation of solar panel. Pole anchor and Earth Anchor are fit for outdoor as the spiral pile mounting system adopts special materials that can resist corrosion, like HDG (hot dip galvanizing) and anodized silver15μm, screw pole mount system is adaptable for different soils. Additionally, it is easy to install. After it is removed, the vegetation can soon recover to reduce harm to surroundings.
Advantages:
1. Simple installation
There is no need to do welding or surface treatment, which saves time and cost. You just need to drill. Generally speaking, it just takes one day to install one screw pole mount system with 100-200 ground screws.
2. Large-scale application scope The screw pole mount system is suitable for different soils, like soft soil, bed rock, swamp and slope with more than 30°..
3. Spiral pile mounting system can work together with different support structures. The ground screw can be made according to client`s requirements.
4. Adaptable for different environment and environmental-friendly
There is no need to do much preparation for installation and there is no harm to environment during installation. Besides, ground screw can protect PV equipment and can be recycled.
5. Convenient transformation
Screw pole mount system can be transformed easily without damage to vegetations. Additionally, it is simple to reinstall.
the advantages of ground-screws for mounting solar photovoltaic systems
-Usually less invasive and landscape-altering than traditional mounting systems such as the half A-frames that are typically installed on cement slabs
-Screws can be easily adjusted to less serious gradients so mounting-frames are installed level: less complicated earthwork and engineering involved as compared to cement slabs
-More aesthetically pleasing than a cement mounting platform: shade-tolerant grasses and plants can easily grown beneath them
