In the production process of laying hens, adopting the “medium change†feeding method can receive good results. This method is described as follows: The first is that "time has changed." Feeding 3 times a day, the time can be determined according to the season (for example: 5 o'clock in the summer, 12 o'clock in the morning, and 5 o'clock in the afternoon). However, after feeding again, the time for feeding each time must be delayed by about 15 minutes in order, delayed for 5 days, and then returned to the time for starting the determination, 5 days for one cycle, and so on. This is done to consciously starve chickens and make chickens eat more. Its hunger is short-lived and does not affect the health of the chicken. The second is "Feeding has changed." The laying hens must feed the full-price compound feed, and cannot feed a single corn (2445, 2.00, 0.08%) or other single feed. This is a principle to be settled. However, in the usual feeding process, it is necessary to be flexible and changeable. Mixed feed can be mixed with fresh and juicy vegetables to help the leaves, wild vegetables or leftovers and so on. In doing so, the dietary nutrition of the chicken can be comprehensive, which can not only improve the palatability, but also save compound feed and reduce the cost of feeding. Practice has proved that adopting the feeding method of “changing in the middle and changing the way†can help the chicken to maintain a strong appetite, increase digestion and absorption and utilization, and provide high feed returns. The chicken’s production performance can be fully utilized, and the number of eggs produced is large. Big head and high quality. Chicken farmers may wish to try.

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.
