Succulent feeds are divided between rhizomes (eg, sweet potatoes, potatoes), straight roots (eg, carrots), and melons (eg, pumpkins). It is one of the most important feeds for dairy animals because of its high water content, high sugar and starch in dry matter, rich vitamins, good palatability, and high digestibility. The most common methods for using succulent feeds are described below. 1, sweet potatoes. The raw and fed milk and livestock are all eaten (but the digestibility of cooked protein can be increased by a factor of two), especially for milk cows during lactation to help digestion and increase milk yield. The protein content of fresh tubers (1.1%) is lower than that of corn, and its feed value is only 25% to 30% of that of corn. If its dry powder (crude protein content of 4.47%) is used as an energy feed, the value is close to that of corn when fed under proper balance. When the Department of Dry Food is mixed with soybean cake or Yeast as a basic feed, the feed value is equivalent to 87% of corn. The amount of fresh potato chips is approximately 20 kg per head per day. Sweet potato vine leaves are juicy, palatability is good, fresh or silage fed after the effect is good, dairy cows fed 30-40 kg per day, dairy goats reduce it. Black spot tuber can not feed, so as not to cause poisoning. 2. Potato. Contains 17%-26% of dry matter, of which 80%-85% are nitrogen-free extracts, low crude fiber content, easy to digest; crude protein accounted for 9% of dry matter, high biological value, vital for dairy milk production . The amount of sweet potato was fed daily. Protein, minerals, and Vitamin supplements must be added when feeding. Potato stems and leaves are green, soft and juicy, and they are also good green feed resources for dairy animals. However, because they contain solanine, they have poor odor and must be mixed with other feeds for silage and then fed. 3, carrots. Characteristics are particularly rich in carotene content (100 mg / kg or more), most of the nutrients are nitrogen-free extracts, but also contains a number of sucrose and fructose and a large number of potassium, phosphorus and iron salts. A small amount of carrots can meet the needs of the carotene of dairy animals (especially in winter and spring), which is beneficial to increase milk production and dairy quality. The cows are fed 25-30 kg on a daily basis, 5-7 kg of bulls, and the dairy goat is reduced. Wash and chop when feeding. Sand dressing should be used during storage. Carrot leaves are green and juicy and can be fed whole cows, sun dried, or minced and mixed with other feeds (such as corn). 4, beets. Sugar beet contains many sugars, high dry matter content (20% -22%), and lack of protein, mineral salts in potassium, nitrate form, so put too hot and easy to poisoning. Dairy cows were fed 25 kilograms a day, and dairy goats reduced it. It is not advisable to feed male rams for a long period of time in order to avoid urethral calculi. Freshly harvested sugar beets can be fed directly, which can easily lead to diarrhea in cattle and sheep. The results of feeding after short-term storage are good. Sugar beet due to more sugar, should be mixed with potatoes, pumpkins, green corn and other storage. In long-term single feeding of sugar beets, indigestion, bloating, diarrhea, and anorexia can occur. Attention should be paid. When sugar beets are harvested in sugar beet production areas, care should be taken to collect roots, leaves, and fine roots that have been cut from roots for feed. Sugar beet slag has a high moisture content (90%), dry matter with less nitrogen-free extracts, more crude fiber, and no vitamin D and carotene. These substances need to be supplemented separately. Dry residue cows can feed 3 to 5 kilograms a day. 5, pumpkin. The most abundant nitrogen-free extracts are starches and sugars. They are also rich in carotene and are particularly suitable for feeding dairy animals. Dairy cows feed 30-45 kilograms a day under the premise of ensuring the supply of hay. Pumpkin vines can be mixed with legumes, green corn stalks, and wild grasses for silage.
