The temperature of newborn ducklings is about 1.5°C lower than that of ducks, and it is not until 15 days of age that they can regulate their own body temperature. When the temperature is low, artificial warming is required. The optimum temperature is: 1-3 days old 30°C-32°C, 4-10 days old 27°C-29°C, 11-17 days old 23°C-26°C, 18-25 days old 20°C-22°C, 26th It should be maintained at no less than 18°C ​​after age.
Drinking water in time
It is advisable to start eating after drinking water, and it is generally advisable to eat at least 24 hours after hatching. Ducklings should master the principle of “drinking water early, eating early, drinking water first, and then eating foodâ€. Ducklings can drink 5% glucose water within 24 hours after hatching.
Timely food
After hatching, the ducklings do not need to be fed on the first day so that it can absorb and use the yolk in the abdomen. If the ducklings dry on the second day, they can stand still and spin or walk in the duck bar. One-third of the ducklings resemble in shape. In the foraging state, the ducklings in the hand-tested ducks stretched their necks and opened their mouths to give a call. At this time, they could drink water, and they could start eating about 1 hour after drinking. The first feeding can be generally used broken corn, broken black beans, broken brown rice, etc., the above feed boiled matured into the water and then dip and then picked up. Feeds that are fed for the first time are required to be free from raw, hard, hot, rotten and sticky. The second time it can be turned into a duckling full-grain pellet feed.
Scientific feeding
Put two pieces of plastic film on the ground, put a piece of feed on one side, raise the other one's height, and put 2 centimeters of deep water in the middle, first introduce the ducklings to the water to learn the action of feeding. After the man pulls out the droppings, let the young ducks. Feed the feed plastic film on the food, so it will not foul the feed. Spread the feed on a tarpaulin or a plastic sheet. Spread it evenly, scatter and sip and eat. Fresh feed, clean drinking water, food trough, drinking trough to keep clean.
Discharge management
Use a tub to hold half an inch of deep water. It is advisable to use water to submerge the infancy of the ducklings. Put the ducklings in and let them stand in shallow water for about five minutes. Note that dropping water at 12 weeks of age does not soak the fluff of ducklings to avoid freezing. After the water is drained, let the ducklings rest on the playground and wait until the fluff is dry to rush into the nest. With the increase of the age, it is appropriate to extend the water release time until all-weather grazing in paddy fields, rivers, lakes and other waters.
Make up the green material
From the third day after the hatchlings are hatched, 10-20% of the green feed should be gradually added to the daily feed. The green feed should be chopped and mixed with rice, or the green feed should be sprinkled on the water to allow the ducklings to be free. Eating. Often feed green material leaves, water plants, duckweed and so on.
Feeding "foraging"
As the saying goes: “The goose should be green and the duck should be squeaky.†“The duckling feeds half the grain, and the duckling eats it.†The duckling is given animal feed on the third day after hatching, at a rate of 10%-20%. , such as snails, small fish, cockroaches, cocoons, etc. It can also be washed with feces, boiled, boiled, fed, or caught and chopped and fed with a bibimbap. Can also be fed with 5% of fish meal bibimboli for half a month.
Feeding "Open Valley"
When the ducklings are raised for 25 days, they can gradually feed “Open Valley†instead of rice. The "open valley" is to soak the millet into the water for one night and cook the millet halfway through the husks the next day. The method of feeding: On the first day, 2 rice and 1 "open valley" are mixed and fed. The second day is the same. On the third day, 1 rice and 2 grains are used. On the fourth day, you can feed the millet.
Eat less meals
Feeding 6 times per day within 7 days, ie every 3 hours during the day and once every 6 hours in the evening; after 7 days, feed 5 times a day, starting from 6 a.m. every 4 hours, 10 a.m. After feeding, put it back into the duck bar; feed it four times during the day after half a month and do not feed it at night; after 20 days, it can be reduced to 3 times a day. 250 animals per group are suitable.
Lighting management
Three days before the ducklings enter the house, 24-hour light is used. After the fourth day, the ducklings are gradually reduced to half-hourly. The ducklings should be gradually adapted to the light-off system. The ducklings should be turned off at midnight and turned on at 5-6 in the morning. The light intensity is suitable for ducks to see clearly.
Properties: It is a volatile, unstable colorless liquid with irritating odor similar to chloroform and ether. Molecular weight is 92.85, density, 1.1806g/cm3, boiling point, 116.11°C, freezing point, -57.2°C, refractive index (nd20), 1.4382, flash point (open cup), 40.6°C, and ignition point, 415°C. It is slightly soluble in water, miscible with many organic solvents, and able to generate azeotrope with a variety of organic liquids.
Main Applications:
Epichlorohydrin is an important organic industrial chemical and a chlorine-consuming product in fine chemicals, mainly for producing epoxy resin, synthetic glycerin, epichlorohydrin rubber, nitroglycerine explosives, glass fiber reinforced plastics, and electrical insulation products, which are widely used in the chemical industry, light industry, transportation, medicine, electronics and other fields. It also can be used as solvent for cellulose ester, resin, and cellulose ether, and the raw material of plasticizer, stabilizer, surfactant, and chloroprene rubber.
Toxicity and Protection: It is highly toxic, absorbed through the skin, and irritating to skin and mucous membranes. In higher concentrations, it has the function of narcotism. When poisoning occurs, there will be eye irritation, conjunctivitis, rhinitis, lacrimation, cough, fatigue, gastrointestinal disorders, nausea and other symptoms. Serious poisoning may lead to anesthesia or even lung, liver or kidney damages. Lethal concentration of human beings is 20ppm. Lethal dose of rat is 5090mg/kg. The maximum allowable concentration in air is 5ppm (18mg/m3). Production equipment needs to be closed, air, circulating, and the operator, wear protective equipment. In addition, due to intense auto polymerization, epichlorohydrin can not be heated in the fire in case of container burst. As for reaction as reagent, it is appropriate to be diluted with inert solvent and slowly added.
Packaging, Storage and Transport:
As ferric chloride or stannic chloride can promote auto polymerization, epichlorohydrin should be stored in dry, clean iron barrel, 200kg each, and kept in a cool, ventilated, and dry place, away from fire and heat. Store and transport in accordance with the provisions of flammable toxic substances.
