Sawdust can also be made into chicken feed

Making sawdust into chicken feed requires three processes of disinfection, fermentation, and ingredients.

disinfection. Sieve the sawdust, small wooden sticks, nails and other impurities in the sawdust. At the same time, sieve the soil with small holes and sterilize it with 0.05% potassium permanganate solution.

The method is: pour the pre-prepared potassium permanganate solution into the cylinder equipped with sawdust, so that the solution does not pass the sawdust 10 cm to 15 cm, and the sawdust is taken out and drained after stirring for about 5 minutes.

Fermentation. The disinfected sawdust is loaded into the pool or cylinder and layered and compacted. Every 15 to 20 cm is sprayed with a watering can with warm water of 30Â°C to 40Â°C once. Every 10 kg of sawdust is sprayed with 12 to 14 liters of water, pool or cylinder. After loading, press the heavy object and open it after 3 to 5 days. Fermentation in winter should ensure that the room temperature is not lower than 15Â°C.

Ingredients. Before using the sawdust, it must be boiled for 40 minutes to 50 minutes. After filtering out the water, add 10 grams of sawdust plus 200 grams of vegetable oil, 150 grams of salt, 15 grams of monosodium glutamate, and 30% to 50% of the energy feed. can.

Nucleic Acid Isolation Analyzer

Nucleic acid extraction instrument, is the application of supporting nucleic acid extraction reagent to automatically complete the sample nucleic acid extraction work of the instrument, nucleic acid extraction instrument is divided into two categories: one is a large automatic, generally known as automatic liquid workstation; The other is a small automatic nucleic acid extractor, using packaged reagents to automatically complete the extraction and purification process. Large automatic liquid workstation is suitable for extracting thousands of specimens of the same kind at a time because of the high cost of equipment and operation, so it is really applied less; And small automatic instruments, because of the low cost of equipment and operation, easy to operate more and more applications.

Purification Nucleic Acid Extractor,Nucleic Acid Isolation Analyzer,Nucleic Acid Isolation Analyze

The detection element scans the binding area and converts the optical signal to electrical

signal. The voltage variation between test line and background has a linear relationship

with the antigen concentration which can be used to calculate the concentration. In

conclusion, the antigen concentration in whole blood, plasma, serum, urine can be

calculated quantitatively according to the optical signal of the test line.
