Production Line Description
Caragana korshinskii is a kind of forage plant with good nutrition. It is a leguminous deciduous shrub with a plant height of 150-300 cm or more. The bark is green to golden yellow and the root system is particularly developed. It is a dry grassland and desert grassland sandy xerophytic shrub , Extremely resistant to drought, cold and barrenness, not afraid of wind and sand. The branches and leaves of Caragana korshinskii are lush and rich in nutrients. During the vegetative period, the branches and leaves contain crude protein up to 20%, crude fat 3 to 5%, and crude fiber 25 to 33%; seeds contain 27.4% protein, 12.8% crude fat, and no 31.6% of nitrogen extract is an important source of nutrition for herbivorous livestock. Cows, sheep, pigs and poultry are often fed with Caragana korshinskii, especially those treated with biotechnology, which have significant effects on accelerating the growth and development of livestock, increasing weight gain, increasing milk production, and promoting the development of reproductive functions.
II. The Nutritional Value of Caragana Korshinskii
The main nutrients of Caragana korshinskii include crude protein, crude fiber, vitamins, crude fat, nitrogen-free extract, amino acids and lignin, as well as a small amount of fructose and glucose. The nutritional value of Caragana korshinskii varies greatly in different growth periods. During the vegetative period, the content of crude protein and calcium is higher, and the content of cellulose is lower. This is the period when the forage value of Caragana korshinskii is the best, from flowering to fruiting. The content of crude protein and calcium began to decrease significantly, while the content of crude fiber began to rise. The quality of the crude protein contained in Caragana korshinskii is good. It contains a variety of amino acids required by livestock and poultry. The content of essential amino acids is even higher than that of general cereal feed and other straw feeds. Bars are used to supplement the problem of insufficient protein and can be used as an ideal raw material for crude protein in feed processing.
Comparison of nutrient composition of Caragana korshinskii with leaves, forage grass and crop stalks
The test results of Luo Huidi et al. showed that the crude protein content in the leaves of Caragana korshinskii reached 27.5%, the crude fat content reached 3.5%, and the crude fiber content dropped to 12.3%. These components are far better than other leaves and most pastures; The main nutrient content is higher than that of various crop stalks, and its crude protein content is 3 times that of corn stalks and 5 times that of sorghum and wheat stalks. Gongjian etc. harvested the young branches of Caragana korshinskii at the initial flowering stage, and dried them naturally. After the stems and leaves were separated, they prepared Caragana korshinskii powder (stem-leaf ratio of 5:3). The measured nutritional value was very high, comparable to silage alfalfa; Caragana korshinskii powder not only has high crude protein content, but also has good protein quality. It is rich in essential amino acids, especially lysine and alfalfa grass powder (national standard first level). The content of various trace mineral elements (except selenium) Outside) are higher than the national standard first grade alfalfa meal, detailed data are shown in Table 1.

It uses advanced biotechnology to process Caragana korshinskii to produce pelleted compound feed for Caragana korshinskii, which greatly improves the digestibility of the caragana. Caragana korshinskii is a good way to replace grain and grass to develop aquaculture industry, which can greatly reduce the cost of the aquaculture industry and has a huge market potential.
IV. How to Make Caragana Pellets
Flow chart of caragana korshinskii production line
(1) Take the branches and leaves of Caragana korshinskii and dry them to remove impurities;
(2) Cut the branches of Caragana korshinskii mechanized into sections and cut into 2-3 cm;
(3) Then knead the cut Caragana korshinskii branches into thin grass nodes or filamentous grass powder, the length of grass nodes or grass powder is 1-3mm;
(4) Use a pulverizer to pulverize Caragana korshinskii powder or grass knots into fine powder with a fineness of 350-450 mesh;
(5) Dry corn stalks and crush them into fine powder with a fineness of 100-150 mesh;
(6) Mix the crushed caragana and corn stalks according to a weight ratio of 6:4, stir evenly, spray water during the mixing process, so that the moisture content of the raw material is 10% to 18%;
(7) The well-stirred mixture is fed into the granulator, and the granular material produced by the granulator is the karanga pellet feed.
V. Feed Application of Caragana
When feeding animals and poultry with Caragana korshinskii feed, a certain amount of concentrate should be added to the diet and fed with the korshinok feed. According to the actual situation in each region, it is advisable to adopt a low-precision method. In addition, inorganic salts and vitamins must be added to ensure that livestock get sufficient nutrients. In order to improve the utilization rate of Caragana korshinskii feed, it must be formulated according to the different production uses and growth stages of livestock and poultry, and according to their nutritional requirements, combined with local feed resources, so that the nutrition is comprehensive and easy to digest. If the diet is matched properly, the utilization rate of the crude cellulose of Caragana korshinskii can be improved, so in order to effectively use the resources of Caragana korshinskii, attention should be paid to the mixing method. For example, if the proportion of concentrate is too large when feeding sheep, it will cause waste and cause indigestion. Therefore, the ratio of crude fiber in the diet for feeding sheep should be controlled at about 20%. Adult sheep should not be less than 1kg, but should not exceed 2.5~3kg. Caragana korshinskii can be made into pellets before feeding the sheep. only. In order to make better use of Caragana korshinskii for the first time, the livestock must be dewormed, epidemic prevention and disease treatment. At the same time, an adaptation period of about 1 week should be given, and limited feeding should be carried out. The amount of feed should be gradually increased, and it is advisable to have no or a small amount of leftover in the trough every day.

VI. Feeding Effect of Caragana Korshinskii
1. The effect of feeding cattle
The branches of Caragana korshinskii in the leafless stage still have certain feeding value. They can replace part of the roughage in the diet to feed lactating cows. While maintaining the normal milk production level, milk fat, milk protein, lactose and milk dry matter have a tendency to increase. .
2. The effect of feeding sheep
During the breastfeeding period of winter and spring ewes, korshinsk is used as the only roughage for the sheep, and then 0.25kg of concentrate is fed, which not only preserves the condition of the sheep, but also has a daily gain of 8.33g. In addition, experiments have shown that the use of caragana and corn stover to feed big-tailed Han sheep can significantly increase the feed intake, feed intake and feed efficiency of the sheep; from the perspective of weight gain and economic benefits, the matching ratio is 2/3 Caragana and 1/3 corn stover are best. In the process of using Caragana korshinskii, pay attention to the matching of forages, and control the feeding ratio of Caragana korshinskii not to exceed 50% to 65%. It is recommended to use more than 2 years of raw korshinskii in production. This is because the two-year-old Caragana korshinskii has relatively thin branches, low lignification, higher feed utilization rate of sheep, better feeding value, and more economical and reasonable.
3. Characteristics of Caragana Feed
(1) Rich in nutrition, good palatability, livestock love food, digestibility and utilization rate increase overall.
(2) It is easy to store and transport. It can be stored for more than 3 years without opening the bag. The feeding effect is good. Feeding cattle and sheep in winter can significantly increase the rate of weight gain and milk increase. 3. Concentrated feed can be saved. Because of the relatively high nutritional value of Caragana korshinskii biological feed, the proportion of concentrated feed can be appropriately reduced to reduce feeding costs.
Seven. Benefit analysis
Economic Benefits: The benefits of biotechnological treatment of coarse feed such as Caragana korshinskii are: firstly, the utilization rate of the forage material after microbial transformation is improved; secondly, the forage material after microbial treatment can increase in value; The forage feed produces more economic benefits than feeding untreated roughage.
