Second, the height of the chair should be at the same level as the knee, that is, when the old man is sitting, his feet can be placed flat on the ground. At the same time, the length of the chair seat should be the same as the length of the old man's hip to knee, so that the knee joint can be maintained at about 90 degrees, and the ankle joint can be in a natural drooping rest state.
Introduce several feed anti-mildew methods
In 2004, quite a few localities suffered from rare autumn rain in the past 100 years. They had less sunshine hours, high air humidity, and the water content of corn, soybeans, sweet potatoes and other feeds exceeded the standard, and some of them even sprouted and mildew, and their quality deteriorated. Now introduce some kinds of feed anti-mildew methods for reference. 1. Grab the air on a sunny day and reduce the moisture content. Farmers can package dried feed ingredients in woven bags and store them in a sunny place. 2. Livestock and poultry farms and specialized households should have less income, and the feed warehouse should be well ventilated and dry on the ground. The cement floor is also easy to return to the tide. It should be covered with plastic film to prevent moisture, and then store the feed, and diligently inspect it. It is found that the temperature is high and the air is blown out in a timely manner. If the amount of material is large, feed anti-oxidant and mildew-proof agent should be added. 3. Feed anti-oxidant and anti-mildew agent. Antioxidants are suitable for animal feed containing high-fat fishmeal, shrimp meal, and vitamins A, D, etc. The feed is oxidized by oxygen, peroxide, or unsaturated fatty acids in the air. To prevent this oxidation, a certain amount of antioxidant should be added to the feed. Butylated hydroxyanisole: It is a white or yellowish waxy crystalline powder with specific phenolic odor and irritating odor and is stable to heat. This product is currently a large number of oil antioxidants, this agent also has strong bactericidal power, with 0.025% can completely inhibit the growth of Aspergillus flavus. 0.02% can completely inhibit the growth of other molds such as Penicillium and Aspergillus niger in feed. The added amount is 0.1-0.2 g/kg feed. The drug is first formulated into an emulsified mother liquor, which is fully stirred and premixed with the feed containing the higher fat, and then mixed with other feeds. The main effect of the anti-mold agent is to inhibit the metabolism and growth of microorganisms. The length of anti-mildew depends on the concentration of anti-mold agent. Anti-mold agents play a role mainly from two aspects: one is to destroy cell walls and cell membranes, and the other is to destroy cell enzymes. Sodium benzoate: white granules or crystalline powder with a slight benzoin odor. Sweet and astringent, stable in the air, soluble in water. The amount added is 0.1%-0.2% of the feed amount. well mixed. Potassium sorbate: A colorless or white scaly crystal or crystalline powder. Odorless or slightly smelly. Unstable in air, can be colored by oxidation, hygroscopic, soluble in water. Its advantage is that it can inhibit the growth of harmful molds without affecting the growth of beneficial microorganisms. Calcium propionate: Nearly white or light yellow powder or powder. Soluble in water, there is a specific smell of propionic acid. It can inhibit the growth of mold, bacteria and yeasts, and can be used as a supplement for feed calcium. Add 3-7 kg per ton of feed. Antibiotics: It is an off-white powder. Large surface area, exhaustion, no odor. Bacteria, mycotoxins and other impurities capable of adsorbing macromolecules can be used to prevent mildew scorpion toxin poisoning caused by mildew feed, and have a certain therapeutic effect on mildly mycotoxin leaf poisoned livestock and poultry. The amount of mixed feeding was 0.03%-0.05%, and the amount of treatment was 0.1%-0.15%.
