Due to the low temperature in the winter and spring seasons, if the goats drink cold water or even ice slag water, the sheep are not willing to drink and will cause the sheep to have insufficient drinking water. This not only slows down the digestive process of the sheep's feed, impedes metabolism in the body, reduces sensation, but also causes various diseases. Therefore, it is necessary to create water conditions for the sheep in production to ensure adequate drinking water. Drinking temperature. If the temperature of water consumed by the sheep is too low, the water must absorb the heat from the sheep itself, which will reduce the utilization of the feed. Therefore, the temperature of the sheep's drinking water in the winter and spring season is preferably 20 °C ~ 30 °C. Drinking water form. In order to promote the sheep to drink more water and drinking enough water, the sheep can be given concentrated feed soup. First use boiling water to open the concentrate feed, stir evenly to make it into a paste, and then on a certain amount of water, stir evenly to the sheep to drink. Drinking water quantity. Sheep consume 1 kg of dry matter and need 3 to 5 kg of water. Therefore, in winter and spring, depending on the situation of sheep feeding on forage grass, the sheep should drink 3 to 5 times of dry matter quality water. Drinking time. Fasting drink sheep, if the water temperature is low, the sheep's body temperature will drop suddenly, easy to make the sheep a cold fever, pregnant ewes fasting drink cold water easy to abortion. In the production, the sheep should be given water after feeding the grass for 1 hour. This can also make the water and the forage mixed well in the rumen of the sheep and help digestion. Drinking times. It is advisable for the sheep to drink water in the morning and evening 2 times. Drink at least once if conditions are not met, but be careful about drinking.
Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
