Milk livestock should be fed succulent feed
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 and sweet potatoes are eaten by mature and fed cows, especially for milk cows during lactation to help digestion and increase milk yield. The protein content of fresh tubers is lower than that of corn, and its feed value is only 2-30% of that of corn. If its dry powder is used as an energy feed, it can be fed under proper balance and value is close to that of corn. 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 green and juicy, palatability is good, and the effect of feeding after fresh or silage feeding is good. The daily feeding amount of dairy cows is 30-40 kg and the dairy goats reduce it.
2. Potatoes contain 17-26% of dry matter, of which 80-85% are nitrogen-free extracts, low in crude fiber content, and easily digested; crude protein accounts for 9% of dry matter, high biological value, and it is essential for milk production. important. 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 are characterized by a particularly rich content of carotene, most of the nutrients are nitrogen-free extracts, and also contain a certain amount of sucrose and fructose as well as a large amount of potassium salt, phosphorus salt and iron salt. 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 were fed 25-30 kilograms a day, 5-7 kilograms of bulls, and dairy goats were 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, beet 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 3-5 kg ​​per day.
5, pumpkin content is the most nitrogen-free extracts, which are mostly starch and sugar, but also rich in carotene, especially suitable for feeding dairy animals. Dairy cows feed 30-45 kilograms a day on the premise of ensuring the supply of hay. Pumpkin vines can be mixed with legumes, green corn stalks, and wild grasses for silage.
