Rural chicken farmers are more meticulous about the brooding period and egg production period, and management before and after the start of production is very lax. To do a good job in this period of management work can lay a good foundation for high-yield and stable production of chickens. For this reason, it is very important to strengthen the management during this period. 1. Deworming and epidemic prevention should be completed well before the chickens lay eggs. All epidemics should be done well. The time for epidemic prevention should be different from the epidemic alone, and must not be completed at one time. This will not only stress the flock but also affect the normal absorption of the vaccine. Farmers in rural areas should pay attention, and they must arrange the immunization time properly. The insecticides are arranged around the age of 110 days. 2. It is very important to rectify the flock. Weak chicks should be caught and fed separately before the chickens are laid to ensure that the flock is even and uniform, and weak fowls are given special “care†measures. Individuals who have no feeding value should be resolutely eliminated. To this end, it should also be interrupted once and for all in accordance with the actual situation. 3. If the chicken cages cannot be inspected before they are opened, they should be carefully inspected, thoroughly disinfected, and repair damaged or deformed parts in time to prevent egg breakage. According to actual production findings, the rate of egg breakage has been high because of the cage. 4. Adjusting diets must be done before and after 110-day-old layers. If the growth and development of chickens meets the standards, they can be adjusted and changed feeds to meet the demand of chickens. It is possible to directly feed egg-laying material (do not add shell powder first) and feed full egg-yolk material at 5% egg production to provide a nutrient reserve for egg production. 5. To increase the lighting, it is necessary to gradually increase the light with the opening of the flock. It is advisable to raise the eggs for 17 hours at the peak of the flock. The supplement should be made sooner or later, and the light should not be reduced arbitrarily after the start of production. In addition, the initial production of chicken spirit is excited, highly neurotic, as far as possible to avoid disturbing the flock, so as to avoid stress. China Agricultural Network Editor

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.
