Caragana korshinskii is a perennial leguminous shrub, which is characterized by drought resistance, cold tolerance, and vigorous growth. It can play a role in wind-proof and sand-fixing and soil and water conservation. In addition, Caragana is an important feed resource for animal husbandry. Caragana korshinskii is rich in resources in Ningxia, and the planting area is relatively large. For a long time, korshinsky has been used as feed mainly in the form of grazing. It has not been renewed and utilized reasonably, which has caused a large amount of waste of resources. Caragana korshinskii is rich in nutritional value, and has different nutritional value in different growth periods, and has high feeding value.

I. 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.

II. Processing of Caragana Korshinskii

Caragana korshinskii has a relatively high content of crude fiber and lignin and has poor palatability. If it is fed directly to livestock and poultry without processing, it is difficult to digest and absorb it. Therefore, it is necessary to improve the nutrition of korshinok through reasonable processing and modulation. Value, improve the digestibility and utilization of Caragana, improve the palatability of Caragana, so as to give full play to the feeding value of Caragana.

(1) Caragana Pellets

The prerequisite is at least one caragana pellet machine or a complete set of caragana pellet production line equipment. Caragana korshinski powder can be made into pellet feeds to reduce the contact area between feed and air, reduce oxidation, and use the preservation of nutrients, especially in high temperature and high humidity areas. Preservatives should be added during pelleting to prevent feed Mildew has occurred. Before granulating, the korshinsk must be preliminarily kneaded and then crushed. The length of the grass powder is determined according to the different animals being fed, and then the grass powder is compressed into a diameter of 0.5~1.5cm and a length of 0.5~2.5 with a granulator. cm particles. The utilization rate and feed intake of Caragana korshinskii were increased after granulation.

(2) Ammonification

Ammonification is to pulverize the fresh korshinskii powder into grass powder or break it into filaments, and then dissolve the urea into a solution of 110 per 100g of urea, and spray it evenly on the korshinski powder, and then layer it into the pool. Compaction. The ammoniated caragana feed must be ammoniated in advance before use. Generally, it is required to put it for 10-12 hours on a sunny day and 24 hours on a cloudy day. It can be fed to livestock and poultry only after the volatilization is complete.

(3) Silage

Choose to harvest in the full blooming period when the nutrient components of the korshink are the most abundant, to ensure that the raw materials are fresh, and the water content in the korshink is maintained at about 50%. Before silage, korshinsk should be crushed into forage or silk, and the water content should be adjusted to 50%~70%. In addition, because the sugar content in korshinsk is low, it is necessary to add sugar during silage and add benefits. FuRMB straw starter. Then, it is filled and compacted layer by layer. After the raw materials are filled and compacted, the cover and seal are timely to prevent water leakage, air leakage and deterioration of the silage. Generally, the fermentation process can be completed after 20-40 days. Caragana korshinskii after silage treatment is yellow-green, has a deep sour and aromatic taste, and has a soft texture. The nutritional value is improved, wherein the content of crude protein increases, and the content of cellulose and lignin decreases. This makes the silaged Caragana easily digested and absorbed by livestock. In addition, making korshinsk into silage can also improve the palatability of korshinsk, stimulate the appetite of livestock, and be beneficial to digestion.

(4) Micro storage

Micro-storage is the use of microbial strains to ferment Caragana korshinskii. The following will take the commonly used YifuRMB straw fermentation strains as an example. In order to shorten the micro-storage cycle, the dormant YifuRMB straw fermentation strain must be activated before use to facilitate the growth of the strain. Then pour the resurrected fungus into 0.8%~1% salt water and mix well. Caragana korshinskii must be crushed into different lengths according to the different animals being fed before micro-storage. Appropriate amount of corn flour and bran can be added to provide appropriate nutrients for the fermentation of korshinskii to improve the quality of micro-storage feed. Spread a layer of Caragana korshinskii powder, then sprinkle a layer of corn flour and bran, and then spray a layer of YifuRMB straw fermentation bacteria liquid. Generally, it takes 10 to 15 days in summer and relatively longer time to complete the fermentation process in winter. After micro-storage, the crude protein content of Caragana korshinskii increased, and the cellulose content decreased.

III. The Feed Application of Caragana Korshinskii

When using caragana forage to feed livestock and poultry, it is necessary to supplement a certain amount of concentrate in the diet, and feed it with the caragana fodder. According to the actual situation in Ningxia, a low-concentration method should be adopted. In addition, Inorganic salts and vitamins are 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 properly matched, the utilization rate of the crude cellulose of the korshinsky can be improved. Therefore, in order to effectively use the resources of the korshinsky, pay attention to the mixing method. For example, if the proportion of the concentrate is too large when feeding sheep, it will cause waste , It can also cause indigestion, so the ratio of crude fiber in the diet of 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 Feed the sheep after pellet feed. 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.
