Feed pig blood fresh pig blood without water, without salt, solidified and crushed. Adding a pig's blood volume to every 100 duck diets, mixing and feeding, can speed up the growth of ducks and have a significant effect on weight gain.
For the ducks fed 4 weeks before the slaughter of Mulberry leaves, 3% of the mulberry leaf powder was added to the feed. Compared with feeding without mulberry leaves, the meat was finer, the aroma was richer, and the taste was better.
Feed the saprophytic sludge with moisture, protein, cellulose, ash, nitrogen, calcium, phosphorus and other substances. According to the experiment, 10% to 20% of saprophyte was added to the compound feed of 21 to 55 days old ducklings. The growth and development were good, the survival rate was 98%, and the feed was saved and the cost of breeding was reduced.
Feeding soybean milk dried soybeans and processed into soybean meal storage. When the bean flour is used, it is brewed into a soymilk with a suitable amount of boiling water. According to the amount of 65 grams of soy bean powder, 10 ducks are fed twice a day, and the growth rate is significantly increased.
4G Mini Camera Structural components
The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
