Beef cattle commonly used feed is divided into 8 categories, namely, green feed, roughage, silage, energy feed, protein feed, mineral feed, vitamin feed and additive feed. Here are three commonly used feeds: Roughage is characterized by a wide range of resources and low cost. Its nutritional value is low, manifested as low protein content, its protein content in the 2% -20%, while the crude fiber content is high, in the 20% -45%. In addition, the large volume and bad palatability, cattle feed intake of such feed is limited, but can be easily ruminant after eating cattle. The source of roughage can be divided into three categories: First, hay, with fine stems of pasture, weeds or
Other plants as raw materials, the natural (sun) or artificial (baking) drying to long-term storage. Hay is a good quality raw material for beef cattle. General grass hay contains protein 6%-9%, legume grass hay contains protein 15%, even more than cereals concentrate; Second, straw feed, refers to the harvest of various crops after the straw, including stems and leaves, Such feeds include wheat straw, rice straw, soybean straw, corn stalks, etc.; third, clamshell feeds refer to the by-products of the crop threshing mill, including the outer pods of seeds, oyster shells, and some pod seeds such as wheat bran, soybean husks, etc. . Green feed includes natural wild grass, cultivated pasture, barley crops, available fresh leaves, and the like. This kind of feed protein is rich in content, generally up to 8%, and is the main source of multivitamins. Each kilogram of grass contains 50-80 milligrams of carotene, vitamin B group and vitamin C, E, K, etc., calcium, potassium, etc. Alkaline elements are also abundant. At the same time, it is also the main way for livestock to consume water. Green feed has good palatability, high digestibility, and can stimulate cattle's feed intake. Silage is a feed made from fresh barley forage crops, pastures, weeds, corn stalks, and various kinds of vines, which are chopped into silos or silage towers and fermented by microorganisms. Its advantage is that some nutrients can be preserved for a period of up to 2-3 years or longer, which can guarantee a balanced supply of green fodder throughout the year. In addition, a large amount of lactic acid and aromatic odor are produced through the fermentation of microorganisms, and the palatability is good, so that the digestibility can be improved.
The 5XZC-L laboratory
seed cleaner & grader is precision equipment for particulate material
cleaning and grading. It is suitable for separation of all seed types, as
grain, grass seeds, flower seeds, vegetable seeds, herb seeds and so on.
Working principle:
Lab seed cleaner is mainly used for all kinds of seed processing
characteristics test and research. It is also widely used for quantity
high-value seeds cleaning and size classification. The seed cleaner is air
screen structure. It has former and rear dust separating air pipes, so you can
clean the dust, light impurities and blighted seeds from good ones. Vibrating
sieve trunk is installed 3 sieve layers in the upper, middle and lower part.
First sieve layer is used to separate large impurity & large seeds. Second
sieve layer is used to separate small impurity & small seed. The rest seeds
are qualified seeds and they go to main discharge outlet. By adjusting the
frequency converter button, you can control the sieve trunk vibration and control
material running speed on sieve screen surface. There are also several air
volume adjusting handles to help you get the suitable air suction. So you can
well manage the seed cleaning effect by adjust trunk vibration frequency and
air volume. At bottom of the sieve trunk, there is an air filter. Dusty air
produced after winnowing will be discharged after filtering. This is
environmental protection design.
Feature:
Lab seed cleaner & grader is two air screens structure. The front and rear part
both has one air cleaning system. In air cleaning procedure, it removes dust,
light impurities and unfilled seeds. Vibration sieve trunk is equipped with three
sieve layers which used to separate large impurity, and small impurity. After whole
cleaning processing, qualified seeds are separated from impurity.
