"The cow is the farmer's treasure." The hot weather in summer and autumn, direct sunlight for a long period of time, plus rushing in and grabbing crops, and enlisting intensities are the key periods for conservation and service in one year. During this period, cows are prone to suffer from heat stroke; because thunderstorms are more, coupled with damp, poor ventilation, cattle are also susceptible to colds, if not timely treatment, it is easy to develop bronchitis or pneumonia; because of heavy labor, frequent drinking Dirty cold water, cattle are also prone to gastroenteritis and dysentery; summer calves and blood-sucking insects are active, because over-compulsory cattle body resistance caused by decreased, susceptible to leptospirosis and filariasis; summer and autumn cattle farming also Predispose to eye diseases, especially conjunctivitis, must be promptly prevented and treated. How to prevent diseases so that cattle can survive the summer and fall seasons should take the following measures.
In summer and autumn, measures should be taken to prevent the heat and cool the cowhouse to open large windows, increase the number of drinking water and add appropriate amount of salt in drinking water.
Enforcement should be avoided at noon. It should be arranged in the early morning and early evening. Wash the body of the cattle frequently, remove the parasites inside and outside the farm, keep it clean and refreshed, and properly increase protein feed and cool feed.
For the prevention of diseases, Chinese herbal decoction can be used to allow the cattle to freely drink or fill. (1) Pingwei Powder has dampness, spleen, and qi and stomach effects. Prescription: 500 grams of herb, Magnolia officinalis, 320 grams of dried tangerine peel, licorice (fried) 200 grams, 50 grams of ginger, jujube 100, is divided into 5 copies, taking a daily decoction. (2) Use 70 grams of wild chrysanthemums, light bamboo leaves, and Houttuynia cordata, 20 grams of orange peel, once for Jianshui, once every 3 days to 5 days. (3) 40 grams of honeysuckle, 36 grams of Anemarrhena, 40 grams of gardenia, 35 grams of Forsythia, 70 grams of gypsum, and 10 grams of licorice decoction, once a day, for 3 days to 5 days.
Plant extraction process
1. Select plants/herbs. No more than ancient prescriptions, prescriptions, folk herbs to find. At present, common and uncommon herbs have been studied. At present, it is mostly to increase the amount of medicinal materials to extract and separate components with low content, or to find medicinal plants that have never been studied from miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. The extraction. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (low polarity → high polarity). Daily medicine decoction effective, water and ethanol and other solvents with large polarity, such as artemisinin boiling ineffective extraction with petroleum ether and other solvents with small polarity. Common medicinal materials water/alcohol/ether to go through, separation and identification of more compounds.
3. The separation. This is the most important work. In the solution extracted from the second step, there are dozens of compounds, usually by column chromatography, which is often referred to as the column flushing. It's a lot of work, it's boring, it's low tech. A master's student might do this every day for two years. The column for separating compounds, as shown below, is as large as 2 meters high and as small as 10 centimeters. Change the solvent condition of mobile phase, change the material of column, different conditions and different separation principles of column repeatedly punching, can be separated from the monomer compound.
