1, nutritional characteristics
Juicy feed moisture content up to 70% to 95%, crunchy, easy to digest, organic matter digestibility was 85% to 90%. In winter, the use of partially juicy feed in the diet of sheep, which is mainly composed of straw and hay, can improve the palatability of the diet and improve the utilization rate of the feed.
Succulent feeds have low energy content, but dry matter contains less crude fiber, equivalent energy equivalent to corn, sorghum, etc.; crude protein content is low, but biological value is high; various minerals and vitamins vary widely. General calcium deficiency, phosphorus, rich in potassium. Carrots are rich in carotene, but sweet potatoes and potatoes lack various vitamins.
2. Common juicy feed
(1) Carrots have high yield, storage and nutrition. Most of the nutrients in carrots are starches and sugars, which are sweet and juicy because they contain sucrose and fructose. Each kilogram of carrot contains more than 36 milligrams of carotenoids, phosphorus content of 0.09%, higher than the normal juicy feed. In addition, carrots also have high iron content. Moreover, the darker the color, the higher the carotene and iron content.
(2) Sweet potato yield is high, crude fiber is small, starch is rich, and energy content ranks first in juicy feed. Sweet potato is cold and should be stored at about 13°C. Sweet potatoes with black shanties have odor and contain toxic ketones. Feeding sheep can lead to panting and severe death.
(3) Like potatoes, sweet potatoes have higher energy content than other juicy feeds. Potatoes contain solanine, which is high in shoots, immature tubers, and tubers that turn green during daylight storage. Too much feed can cause poisoning. When feeding, the germination site should be removed and carefully selected to prevent poisoning.
(4) Sugar Beet and Sugar Beet The sugar beet has a high yield, sugar content is 5% to 11%, and is suitable for feeding sheep. However, the amount of the sugar beet should not be excessive, nor should it be fed alone. Sugar beet (20% to 22% sugar) Residue left after making juice and sugar is called beet pulp. 80% of the crude fiber in sugar beet pulp can be digested by sheep, so it can be considered as the sheep's energy feed in terms of dry matter. Sugar beet pulp contains more calcium and phosphorus, and calcium is more than phosphorus, which is better than other juicy feeds. Pay attention to dry sugar beet slag should be soaked with 2 to 3 times the weight of water before feeding, to avoid swelling in the digestive tract caused by a large number of swelling caused by the disease.
Beet residue plus molasses and 7.8% urea can be made into sugar beet residue products, it is hard, slow digestion, high urea utilization, good safety, can increase feed intake by 20%.
