How to raise goslings in summer? How to feed and prevent diseases?

Due to the hot summer weather, Gosling breathing faster, loss of appetite, coupled with mosquito and fly harassment, Gosling body function is not sound, disease resistance is weak, at this time, daily management should be strengthened to improve the survival rate of Gosling and ensure the benefit of breeding. So how to raise goslings in summer? How to feed and prevent diseases?

Transportation management

After the Gosling comes out of its shell, it will be removed from the nest when the fluff is dry. Should choose lively manner, eyes, sensitive response, yolk contraction is good, dry hair can stand firm, call forcefully, with hands to hold the neck up when the feet contract rapidly. Weak chicks such as big belly and tilted head should be eliminated.

The means of transport, including cars and boxes, should be disinfected before transportation, and the status of goslings should be checked during long-distance transportation. If problems are found, the temperature should not be too high during transportation, and it is best to keep it at 25 ℃ ~ 30 ℃. Land transportation should be carried out in the morning and evening or when it is cool at night, and there should be more vents around the boxes, and more gaps should be left between the boxes in order to maintain air circulation, and rain-proof facilities should be provided to prevent rain. At the same time, it is necessary to reduce the density of goslings, such as carrying about 60 goslings in the box and reducing it to about 50 in summer.

Brooding environment

The daytime temperature in summer may exceed the required temperature for brooding, so we should pay attention to ventilation and keep the air in the nursery fresh. The temperature at night may be lower than the required temperature for brooding, so it should be warmed up at this time, and the natural temperature should not be adopted just because it is summer. Sunshades should be built outside the nursery, and nylon nets or fences should be used on the front walls.

After being transported, the goslings stop for a while in the nursery to rest. Each batch of goslings is large, medium, small or strong or weak, so they must be divided into groups reasonably to achieve the goal of uniform growth and neat development of the whole group. Put the weak chicks closer to the heat source and let them move in the fence for a while.

The brood should be raised in small groups, and the feeding density can be reduced according to the conditions of brooding, generally 20 birds per square meter at the age of 1-5 days, 20 birds at the age of 6 days, 15 birds at the age of 11 days, and 12 birds at the age of 16 days and 21 days. The relative humidity of the brooding house is maintained at 55% 60%. The temperature is 25 ℃ ~ 28 ℃ at 5 days old, 23 ℃ ~ 26 ℃ at 6 days old, 20 ℃ ~ 24 ℃ at 11 days old, and 17 ℃ ~ 20 ℃ after 21 days old. To do group-by-group inspection during the day and night, copy the goslings by hand for 4 or 5 times to prevent the phenomenon of freezing above, heat in the middle and pressure below caused by the stacking of goslings.

Feeding method

Appropriate feeding standards should be established according to different Gosling breeds, developmental stages and production purposes. Under the premise of ensuring its nutritional composition, based on local resources to reduce the cost as much as possible, not only meet the physiological needs of goslings, but also do not cause nutritional waste, so that farmers get greater economic benefits. The quality of raw materials should be good, there is no mildew deterioration and pesticide pollution, should be a variety of raw materials to ensure balanced nutrition, and control the amount of some feed raw materials. If leguminous hay powder is rich in protein, the amount used in the diet can be 15%-30%. Feather meal, blood meal, etc. although the protein content is high, but the digestibility is low, the addition amount should be less than 5%.

The feeding method of "regular and quantitative feeding with 80% less satiety" should be adopted. the goslings hatched by the eggs laid by young goose are fed for about 36 hours, and the goslings hatched by adult goose are fed 24 hours. When the goslings are all able to stand up for the first time to drink water, 0.02% potassium permanganate cold boiled water should be supplied, and 5% glucose water should be provided for long-distance transportation. If the transportation time is too long, if it takes more than 30 hours, the green succulent feed should be chopped and the grass length should be kept at 0.1-0.2 cm to allow it to eat freely, and then drink water. Drinking water for the first time is very important to ensure that every goose can drink water. If you find a few goslings without drinking water, hold their head from behind the head and neck of the goslings, gently fix their thumbs and index fingers on both sides of their beaks and make them open their mouths and point water into the water for 2 or 3 times. After drinking water for the first time, it is necessary to ensure that the goslings are always clean and cool and let the goslings fully move. When the goslings show pecking behavior, they begin to feed. It is generally fed 24 to 36 hours after shelling, and less frequently in the case of wet powder, 12 times in the first week, 8 times in the second week, and 6 times in the third week. Each feeding should be mixed and fed now, keep the feed fresh, increase palatability, and ensure the feed intake of goslings to promote their growth. Goslings avoid greasy matter, can be washed and cut fresh green feed mixed with chopped rice for 10 to 15 days, the proportion of green materials should be more. Feed 3 times 4 times during the day and 1 times twice at night, and provide clean drinking water. After 15 days, all the green feed can be fed, and the concentrate such as bran, bran and a small amount of corn meal can be fed in the evening.

The nutritional formula of this period is as follows: straw biological feed 70%, bone meal 1%, soybean meal 5%, fish meal 2.2%, corn meal 18%, wheat bran 2.2%, salt 0.3%, shell meal 1%, straw biological feed 75%, bone meal 1%, bean cake 5%, fish meal 3.1%, corn meal 15%, wheat bran 3.5%, salt 0.4%, shell meal 2%. After 7 weeks, 85% of straw biological feed, 1% of bone meal, 3% of bean cake, 2.5% of fish meal, 5% of corn meal, 1% of wheat bran, 0.5% of salt and 2% of shell powder.

The best choice for the first grazing is when the temperature of the outside world is close to that of the nursery room, pay attention to avoid the rainstorm, and generally stop feeding bran and bran. It is suitable for grazing at 5 ~ 9 a.m. and 6: 8 p.m., and the rest of the time can be kept in captivity, properly supplemented with concentrate feed. Each goose is fed 100 grams of compound feed every day, mixed with chopped green feed, and the amount of green feed accounts for about 20% of the compound feed. 35-50-day-old geese should be kept in captivity, and the appropriate feeding density should be 6 geese per square meter. each goose should be fed with 100-150g formula feed and chopped green feed every day, and the ratio of formula feed to green feed should be 3 ∶ 7 to provide enough drinking water. The geese should be put into the water for about 30 minutes every other day. The geese aged 51 ~ 60 days were fed with about 800 grams of formula feed for 5 times 6 times a day.

Disease prevention and control

The prevention and treatment of Gosling Influenza and Gosling plague are focused on in the brooding stage, both of which are acute infectious diseases of goslings with similar symptoms, with the characteristics of acute fever, quick death and high mortality.

Gosling plague is originally a Gosling plague virus, which is the most susceptible to Gosling plague at the age of 7 to 10 days, and does not occur at the age of more than 30 days. It can happen all the year round. The symptoms are severe dysentery, grayish white or yellowish green rice soup-like dilute feces, and mixed with air bubbles. Dyspnea, often snoring, serous secretions often flow out of the nostrils. During the autopsy, the lesions were found in the digestive tract, fibrotic necrosis and inflammation of the small intestine, necrosis and exfoliation of the intestinal mucosa, and the formation of hard emboli in the small intestine to block the intestine.

The hygiene and epidemic prevention system should be strictly carried out and the circle cleaning disinfection should be carried out frequently. The newly introduced goslings should strictly carry out the procedures of isolation, observation and quarantine to prevent the introduction of epidemic disease. One month before laying, one milliliter of Gosling plague vaccine was injected into each goose one month before laying, and two weeks later, the goslings hatched by Gosling eggs had immunity to Gosling plague, and in Gosling plague epidemic area, 0.5ml Gosling plague serum was injected subcutaneously to each goslings after hatching. When complicated with infection, effective symptomatic treatment measures can be taken according to the condition.

The pathogen of goose influenza is Shigella, which occurs frequently in spring and autumn, and the incidence of goslings is high at the age of 30 days. During the autopsy, there were a large number of translucent serous or mucous secretions in the respiratory tract, nasal cavity, larynx and trachea, epicardial hemorrhage and fibrinous pericarditis.

It should be carefully managed and paid attention to environmental hygiene to prevent climate change goslings from being caught in the rain and cold. Oral administration or injection of sulfadiazine drugs can be taken: 0.25g (half tablet) of sulfadiazine tablets is given to each gosling for the first time, and then one tablet is given every 4 hours; one milliliter of 20% sulfadiazine injection is injected intramuscularly for the first time in each gosling, and 0.5 milliliter is injected every 4 hours thereafter.

Treatment with antibiotics: penicillin 20 ~ 50 000 international units, diluted and dissolved with 2 ml of injection water, intramuscular injection, once every 6 hours, continuous injection for 2 days. Or use penicillin 5000 international units, dissolve in the right amount of water, drink within 1-2 hours; with streptomycin 10-20 000 international units, diluted with 2-5 milliliters of normal saline, once intramuscularly, once every 12 hours, until the disease disappears; chloramphenicol 12-15 mg, once intramuscular injection, twice a day, generally 4 times can be cured Mix tetracycline or oxytetracycline into feed or drinking water for internal administration, 200 mg a day for 3 to 5 days.
