Spring repair skills
In the early spring season, there was less hay and crude protein and other nutrients were in short supply. Coupled with the low temperature and high energy consumption of the carcass, the ewes needed more nutrition for pregnancy, lactation, long hair and long velvet. Grazing is far from meeting its nutritional needs and must be supplemented by supplementary feeding. For the main nutrient-limiting factors for grazing, the following methods can be used for feeding. Specific breeding techniques are as follows: The nitrogen source used for supplementing nitrogen sources is urea, which does not exceed 1% of the sheep's dietary dry matter or 2%-3% of its concentrate feed. The specific feeding amount of urea depends on the amount of energy feed in the sheep's diet. Generally, the energy feed can be fed for a long time, and the feed for energy can be fed less when the energy feed is low. Urea must be fed with digestible concentrate or a small amount of molasses, moderate amounts of sulphur and phosphorus, and fed in small amounts one after another. It cannot be fed with bean cakes or quail, nor can it be used to feed sheep that are in conditions of disease and starvation. Poisoning. When using, urea should be sprinkled in the wet concentrate to make it evenly dissolved. It is forbidden to be dissolved in water or fed separately. Sheep fed a urea diet cannot drink water immediately, and it is advisable to drink water after stopping feeding for two hours. If sheep poisoning caused by improper feeding of urea, can be fed a lot of cold water or moderate amounts of dilute acetic acid, yogurt, vinegar, etc., and conditions can be fed to the sheep 10% of acetic acid plus glucose mixture of 1.5-2 liters. Rumen protein and ruminal starch supplementation through rumen technology can increase sheep feed intake, promote amino acid absorption in the small intestine, and increase wool production and milk production. Increased fermentation can supplement grain-based feeds such as barley, wheat, oats, corn, and sorghum, which contain more starch, and can increase the fermentation energy of the diet and increase sheep's utilization of roughage. Compensatory silage supplemented with a small amount of silage corn in the withered period can promote the growth of rumen microbes in sheep, and improve its utilization of roughage. Mineral supplements Sheep may lack mineral elements such as calcium, phosphorus, sodium, potassium, selenium, and copper. They may use supplementary feeds or salt bricks, mineral pellets, or sustained-release devices. L Shape Height Adjustable Desk Lifting slide table is a kind of work table that can be raised or lowered by electric or manual means, which can be used for office, study, painting, writing and other activities. According to different classification standards, lifting and sliding tables can be divided into the following types: L Shape Height Adjustable Desk,Work Office Lift Table,Automatic Desk Lift,Adjustable Lift Desk Suzhou Herstar Medical Technology Co., Ltd. , https://www.hosunherstar.com
1. Functional classification: lifting sliding table can be divided into single motor, double motor and three motor and other different types, with different lifting speed and bearing capacity.
2. Operation mode classification: the lifting sliding table can be divided into pneumatic and electric operation modes, and the moving operation can be realized by pushing buttons.
3. Classification of sliding way: lifting sliding table can be divided into two types with wheels and without wheels. The table with wheels can easily move the position, while the table without wheels is more stable.
4. Desktop material classification: The desktop of the lifting sliding table can be made of different materials, such as wood, metal, glass, plastic, etc., each material has its characteristics and application occasions customized.
5. Size classification: The lifting sliding table can be selected according to the height of the user and the size of the required working space. The common sizes are small, medium and large.
In short, choose suitable for their own lifting sliding table need to consider many aspects of factors, such as function, operation mode, sliding mode, desktop material and size, in order to meet their own work needs and personal preferences.
