Second, age matching and re-allocation. Pairing is best when the pigeon grows to 6 months of age. Early mating will affect the constitution. Pairing and reassembling should be carried out at night. Manually pairing must be performed. Conscious selection of pairs of male and female hens with similar body weight, similar body weight, and uniform coat color should be used. After pairing, the four eggs produced are the same mothers and should be re-matched; after the pairing, no eggs or special-shaped eggs should be reconstituted. After pairing, eggs may not be reconstituted or coccycopheral injection of testosterone propionate, 5 ml each time, 3-5 days after the injection, or to the public pigeons, vitamin E, 1 capsule each to promote cocks Fertility.
Third, the feeding tube at the beginning of the match. Cultivate the newly-matched pigeons and inspect them several times a day for the first few days to see if they are harmonious. If the pairing is appropriate, the pair will get along well after 2-3 days; if they are not harmonious and often fight 4-5 days after pairing, it means that the pairing of pigeons is not appropriate, or both are cocks, or It is a male and a female but does not want to match. At this time, it should be reconfigured in time.
Fourth, the holding period of management. Generally, egg production begins 10-15 days after pairing, and care must be taken to keep the environment quiet. Put a piece of burlap on the egg nest 2 days before the laying of eggs or put some short straw or pine grass in the egg nest that is clean and the same length as the pigeon hair, and record the date of egg production. Prevent rain from entering during hatching. The litter should be promptly replaced when wet and damp. Usually pay attention to check whether the eggs leave the pigeon's abdominal feathers to prevent cold eggs. When hot, you should reduce the amount of bedding, open more windows, cool down with cold water, or spray in the room to cool down. When the temperature is low, pay attention to close the windows and increase the litter to prevent the eggs from freezing and leaving dead embryos. Eggs were hatched 4-5 days and 12 days after hatching. After 4-5 days and 12 days after hatching, eggs were taken 1 time. The zygotes and dead embryos were promptly removed, and the embryos of the same or similar ages were merged and bred together to replace the parent pigeons. Burden, free up time to recuperate and produce a nest egg in advance. At 17-18 days, check out the hatching situation. When it comes to shelling difficulties, it is necessary to peel off shells and give birth.
Fifth, the management of brooding period. Younger pigeons should be given more nutritious feed. The following diet formulas should be used: corn 40%, wheat 30%, pea (mung bean) 20%, and brown rice 10%. Eat small meals and feed 5-6 times a day. In the meantime, management should be strengthened. Pay attention to replacing the litter and keeping the litter clean. When single pigeons can be nested, it is better to use 3-6 days, and the nest time should be at night. The young pigeons are raised on the web at the age of 15 days. The nesting test showed that 1 pair of pro-pigeons can fully feed 3 young pigeons at the same time.
6. Management of the moulting period. The breeder mops once a year at the end of the summer and autumn, and it takes 1-2 months. During moulting, 10% of the hemp seed can be added to the feed, and 200 grams of gypsum powder or 100 grams of sulfur powder can be added to 50 kg of health sand, which has a good effect on moulting the breeder. At the same time to add a variety of vitamins in the feed. During the moulting period, the breeding pigeons are adjusted once. According to the production records and the performance of the pigeons, the breeding pigeons with little production of eggs, poor brooding performance, poor offspring quality and long moulting time are eliminated, and the traits are selected from the reserve breeding pigeons. The good ones make up. At the same time, it is necessary to completely sterilize the breeding lofts inside and outside the breeding loft, as well as the pigeon cages, nest boxes and utensils, so that the pigeons have a new comfortable environment after the moult.
Seven, active prevention and cure of pigeon disease
1, food poisoning: Take a cactus, use scissors to remove burrs, cut into small pieces, put into a bowl or garlic mash into a paste gavage. The light can be cured by filling once, and the heavy one can be fed once every 3-4 hours. The method of filling is to open the dove mouth and use chopsticks or other things to send the cactus paste. The amount of two corn grains can be used each time. But be careful not to hurt the pigeon's mouth and pharynx.
2. Bathing the pigeons: The pigeons have a good spirit. When the climate is warm, they can give the pigeons a bath, usually 2-3 times a week. If there is ectoparasitosis, bathe with medicine. 2500 grams of water is added to each bottle of "Cockroach Essence" to allow the pigeon to have a medicinal bath. The best feathers can be soaked. Bath once a week, the effect is very good.
3, treatment of dysentery: Shenqi Baizhu powder is a traditional Chinese medicine, powder, non-toxic side effects, when used can add a little water, wet, and pinch into a corn kernel size pellets, fill it as appropriate, to treat dysentery significant effect.
Centrifuge tubes are precision-made, high-strength tubes of glass or plastic made to fit exactly in rotor cavities. They may vary in capacity from 50 mL down to much smaller capacities used in microcentrifuges used extensively in molecular biology laboratories. Microcentrifuges typically accommodate disposable plastic microcentrifuge tubes with capacities from 250 Î¼L to 2.0 mL.
Glass centrifuge tubes can be used with most solvents, but tend to be more expensive. They can be cleaned like other laboratory glassware, and can be sterilized by autoclaving. Small scratches from careless handling can cause failure under the strong forces imposed during a run. Glass tubes are inserted into soft rubber sleeves to cushion them during runs. Plastic centrifuge tubes, especially tend to be less expensive and, with care, can be just as durable as glass. Water is preferred when plastic centrifuge tubes are used. They are more difficult to clean thoroughly, and are usually inexpensive enough to be considered disposable.
