Scientific adjustment of winter egg feed

The laying hens in winter are gradually discontinued and enter the rest period. However, the chicken's feathers continue to thicken for safe wintering. According to this natural law and the actual condition of chickens, scientific adjustments are mainly made of the following two points. Thinning and thickening Winter is the resting period of laying hens. The body's demand for nutrients is greatly reduced, and only a small part of the nutrient supply itself is consumed. There is no need to continue supplying high-quality feed for the peak period of egg production. . The principle of feed adjustment should be “reducing fineness and thickening”, reducing the consumption of corn, sorghum, dried melon, fish meal, bean cakes, etc., and adding roughage such as bran, sweet potato noodles and corn kernels, and feeding some vegetables to help the leaves. (such as cabbage leaves, celery leaves, etc.) and carrots and other green tubers juicy feed. The proportion is generally 15% fine, 75% rough, and 10% green. Nutrition In order to ensure the growth and health of layer feathers, the nutritional content of feed must be comprehensive. In the diets based on roughage, attention should be paid to the supplement of minerals, various vitamins, trace elements and various amino acids and other feed additives. Because the production of feathers and the physiological and biochemical metabolism of chickens depend on these nutrients. In particular, net-fed, captive, and caged layer chickens are not able to feed on these nutrients due to site constraints. If they do not pay attention to the addition, they are more likely to affect feather growth and chicken health. When supplementing these additives, attention should be paid to the supply of sulfur, gypsum, and hypnosis, each of which can be added in amounts of 2 grams, 3 grams, and 1 gram per day, respectively.

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.
