1, increase milk production. Adding appropriate amount of vinegar to the feed of dairy cows not only increases the appetite and feed intake of cattle, but also increases the milk production.
2, can prevent potato solanine poisoning. When potatoes are used as feed, all germinated, immature and rotten potatoes cannot be directly used as feed. If they are to be used, the buds and mildew parts can be removed. After appropriate amount of vinegar is cooked, the purpose of detoxification can be achieved. Feeding livestock and poultry is safe.
3. Vinegar can control premature estrus in postpartum sows.
Some sows begin to heat in 5 to 6 days after farrowing. The mating can not be pregnant or the pregnancy rate is very low. However, after the estrus of the sow, the food is rejected, the baby refuses to feed, and the piglets are injured. This affects the survival rate of the piglets. 500ml of sow vinegar can be taken orally once a day for 3 days, then normal eating and feeding can be resumed. If the pig is not estrus for a long time after weaning, 500ml of vinegar and 250g of noodles can be used. Stir well. Feeding sows, sows 3 days after eating can be estrus and mating.
4, prevention and control of chickens. The vinegar-immersed garlic solution can prevent chicken fleas with a cure rate of 97%. Specific usage: Use 100 grams of peeled garlic, put it in a container after mashing, add 500 ml vinegar, soak for 1 to 2 weeks, dilute 4 times with water before use, each serving 0.5 ml drops per bird. Take 3 to 3 times a day for 3 to 5 days to heal. When large groups of chickens are treated, vinegar and garlic may be mixed and fed in the feed, which also has good results. Clinical practice has shown that often feeding vinegar-immersed garlic liquid to chicks can not only increase the appetite of the chicks, promote the growth and development of the chicks, but also prevent the occurrence of a variety of diseases, increase the survival rate of chicks and increase the benefit of raising chickens.
So what does 4K resolution mean?
In the digital technology field, people usually use the binary operations and the pixels to describe the size of the digital image. Due to the huge number of pixels that make up a digital image, the digital image size is usually represented by K. The 10th power of 2 is 1024, so: 1K=2^10=1024, 2K=2^11=2048, 4K=2^12=4096. How many 1024 pixels there are in the horizontal direction means how many K a video includes. Specifically speaking, for example, the resolution 2048×1080, 2048 represents the number of pixels in the horizontal direction and 1080 represents the number of pixels in the vertical direction; similarly, when the resolution is 4096×2160, 4096 represents the number of pixels in the horizontal direction, and 2160 represents the number of pixels in the vertical direction. In the actual production of alphanumeric version and digital projection, the number of pixels in the horizontal or vertical direction of the image needs to be adjusted according to different aspect ratios. Therefore, the resolution of 8847360 pixels close to the 4K image can also be called the 4K such as the resolution 3840*2160 which is common on the market. And strictly speaking, the standard 4K resolution is exactly 4 times the number of pixels of the 2K resolution 2048×1080, and 16 times the number of pixels of the 1K resolution 1024×540.
4K resolution belongs to the Ultra HD resolution, which means that the audience will be able to see every detail and close-up in the photos/videos at this 4K resolution. If 4K resolution is applied to the cinema, the audiencescan cearly see every detail and close-up of the film whichever cornor of the cinema they are at.
4K resolution refers to that the pixel value per line in the horizontal direction reaches or approaches 4096, regardless of the aspect ratio. 4K resolution also has a variety of derivative resolutions, such as the Full Aperture 4K(4096*3112), the Academy 4K(3656*2664), and the UHDTV 4K(3840*2160), etc.,. And in the security and protection field, when we mention the 4K resolution, it refers to 3860*2160, 800W pixels.
4K resolution fits the resolution standard of the new generation of the Hollywood blockbusters. Different from both the so-called high-definition TV (1920×1080 resolution)that we watch at home and the large 2K resolution screen (2048×1080 resolution) of the traditional digital cinema, the 4K resolution means the ultra-high resolution video of the 4096×2160 resolution. The traditional high-definition TV shows the video of 2.07 million pixels, the traditional digital cinema shows the video of 2.21 million pixels, while the 4096×2160 resolution theater can show the high-definition video of 8.85 million pixels.
In conclusion, we should correctly know about the 4K and the resolution, and choose the most suitable resolution when we buy a electric device, the DVR, the security monitoring device or something.
