In order to increase the milk production of dairy cows, it is an extremely important technical measure to feed the cows with succulent feed. Juicy feeds that increase milk production in dairy cows include tubers, tuber feeds, and melons. The moisture content of these feeds is generally as high as 70% to 90%. The content of sugars and starch in dry matter is high, the cellulose content is not more than 10%, and there is a certain amount of minerals. Feeding practice has proved that this kind of feed has good palatability and the digestibility rate is as high as 80% to 90%, which is an important feed for increasing milk production of dairy cows.
beet
Beet dry matter contains 5% to 6% of sugars, 1% to 2% of protein, 1.7% of crude fiber, and 9% of nitrogen-free extracts. When feeding, they should be washed and chopped first. Each cow can feed 30-40 kg per day. The beet feed should not be allowed to stand for too long, so as to avoid nitrate poisoning caused by dairy cows. Beet slag
Fresh beet pulp contains 90% water, crude protein 0.9%, crude fat 0.1%, crude fiber 2.6%, nitrogen-free extract 3.5%, but no carotene and vitamin D. Feeding of sugar beet slag can provide the cow with necessary fillers. Sugar beet residue can feed 3 to 5 kilograms per cow per day.
potato
The average content of dry matter in potatoes was 22%, crude protein 1.6%, crude fat 0.1%, crude fiber 0.7%, and nitrogen-free extract 18.7%. Every 3.5 to 4 kilograms of potatoes is equivalent to 1 kilogram of cereals, and about 80% of dry matter is starch, easy to digest, but the lack of methionine, calcium, phosphorus and carotene, etc., is a typical carbohydrate-rich material containing more water, One of the main energy sources for dairy cows. Every day cows feed 20 to 26 kilograms per day, and pay attention to matching protein, minerals and vitamin supplements in the diet.
carrot
Carrots have a dry matter content of 12%, and are mostly soluble sugars. They contain 1.1% crude protein, 0.3% crude fat, 1.2% crude fiber, and 8.4% nitrogen-free extracts. They are high quality for sire, lactating, and young animals. Succulent feed. When feeding, they should be washed and shredded first. Every day cows feed 20-25 kilograms, and bulls feed 5-7 kilograms. When stored, it is best to use wet sand to prevent rot and nutrient depletion.

hydroponics system-nutrient technique (NFT)
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse". The NFT pulse usually achieves better aeration of the roots as the roots are exposed to air between each feed. A & lsquo; continuous' rss cycle works non-stop. This is often used in commercial operations.
You can easily grow your favorite flowers at home without muddy mess and need to water your plants regularly.
Hydroponics is an ideal way to grow plants in urban areas. This makes it a great hobby that helps you to relax and it is fun to watch the hydroponic plants grow in the garden nft.
