How to improve the survival rate of goslings and how to improve the weight gain rate of goslings

Goose nature herbivorous, with fast growth, tolerance of coarse feed, growth cycle short and other advantages. Based on many years of practice, the author discusses the key measures to improve the survival rate and weight gain of gosling for reference by farmers and peers.

goslings

strict selection

Select goose breeding farms (households) with breeding livestock and poultry production licenses, and purchase healthy goslings that have been quarantined in the producing area; all geese in the same breeding group or the whole farm shall come from the same goose breeding farm (household) and the same batch; select goslings with big eyes, lively behavior, loud cry, bright fur color, good umbilical contraction, clean anus and strong grip; eliminate goslings with tilted head, blind eyes, big belly and blood umbilicus.

rational grouping

Group them according to strength to avoid crowding and reduce death; during feeding, attention should be paid to continuously adjusting the goose group according to the growth, development, size and strength of geese, so as to make the size and strength of each group of geese of the same age consistent as far as possible, so as to facilitate feeding and management; in the process of brooding, if any gosling with poor appetite, slow action and weak physique is found, it shall be timely selected and fed separately, carefully managed to improve the survival rate of brooding.

boiled water

Goslings generally in shell 24 hours after the first boiled water can be eaten, to ensure that the drinking water does not leak, to prevent bedding and feed mildew. Glucose and multivitamins are added to drinking water, which is conducive to cleaning up gastrointestinal tract, stimulating appetite, discharging feces and absorbing nutrients. 30 minutes after drinking water for the first time, fresh green material can be eaten, cut into filaments and mixed with soaked broken rice or broken corn with less moisture, mixed with 2:1 feeding, scattered on plastic paper, to induce its intake. The first feeding should not be too full, start feeding 4 ~5 times a day, 3 weeks old 6 ~8 times a day, including feeding 2 times at night, to 4 weeks old, the proportion of solar eclipse can be adjusted appropriately, should be added to the feed 1.5% bone meal, 2.5% shell powder and 0.3% salt, at the same time, can be fed some cake meal, bran, rice bran, etc., reduce the number of feeding times a day, the feeding amount of gosling should be controlled at 80% full.

reasonable exercise

After eating, we should drive the gosling to move once every 1 hour or so, and pay more attention to driving its activities at night or in cold weather, so as to regulate body temperature, enhance physique and improve survival rate.

Heat preservation and moisture protection

Gosling thermoregulation function is not perfect, to low temperature and temperature sudden change adaptability is very weak. The temperature is low, the goslings crowd together, often because of suffocation and death. When the temperature is high, the gosling is listless, eats less, drinks more water, opens its mouth to breathe, and calls short, thus affecting its growth and development and easily inducing respiratory diseases. Long-term high temperature can cause a large number of goslings to die. Therefore, the temperature of goose house should be controlled at 28℃~30℃ within 1 week old, and then decreased by 2℃ every week until it dropped to about 20℃.

When the environmental humidity exceeds 80%, goslings are stunted and stiff geese are formed. Pathogenic microorganisms and parasites are easy to breed in high temperature and humidity environment, feed and bedding are easy to mold, goose flock is easy to develop aspergillosis. Low humidity will undoubtedly have serious consequences for the growth and development of waterfowl, and it is easy to cause too much dust in the environment and cause respiratory diseases. Suitable humidity: 60%~65% within 10 days old, 65%~70% above 10 days old.

timely grazing

The time to start grazing should be determined according to the temperature. When the temperature is high, grazing can be done at 1 week old. When the temperature is low, grazing can be done at 2 weeks old. Grazing should pay attention to: First, when grazing begins, the gosling after feeding is placed on the flat young grass ground near the brooding room, and the grass is freely eaten. The distance should be short, the time should be short, and gradually extend later, late release and early harvest. Grazing is not allowed on rainy days or under the scorching sun. After grazing for 1 week, when the temperature is suitable, you can combine water, drive the gosling to shallow water, let it go into the water by itself, play in the water, do not force it into the water, in case of cold. Second, it is best to choose in sunny windless weather, dew dry after, so as not to cause goose diarrhea. Third, the first grazing should be fed half full and then grazing to the nearby flat grassland to let the geese move freely for 1 hour. Later, the grazing time and distance were extended day by day. For adult geese over 4 weeks old, grazing all day can be used to train the physique and foraging ability of gosling, reduce concentrate supplement feeding, reduce feeding cost, and supplement feed properly after grazing.

health and epidemic prevention

In order to prevent the occurrence of diseases, the brooding room should be cleaned frequently, the bedding should be replaced, kept clean and dry, two kinds of disinfectants with different components should be used regularly, the brooding environment should be disinfected alternately, and the feeding trough and drinking water should be cleaned every day. Goose farms (households) should be vaccinated according to the immunization plan, combined with the actual situation, selectively carry out epidemic disease vaccination work, and pay attention to the selection of appropriate vaccines and immunization methods. At the same time, to prevent rats, snakes and other harmful animals harm gosling.

strengthen management

At ordinary times, we should pay attention to observe the health status of goose flock, timely isolate and observe sick goose, find out the cause, select targeted therapeutic drugs, and improve the treatment effect. It is strictly prohibited to raise livestock and poultry together to prevent the spread of germs. According to the size of gosling, physical strength to do a good job of group health, so that gosling group feed evenly, grow neatly, with 60 ~80 in each group is appropriate. The suitable density is 15 ~20 small geese per square meter at 1 week old, 10 ~15 small geese at 2 weeks old, 6 ~10 small geese at 3 weeks old and 5 ~6 small geese at 4 weeks old. Pay attention to feed, drinking water should be fresh and pollution-free. At the same time, to create safe environmental conditions, so that geese are not disturbed.

prevent disease

Goslings should be injected with anti-gosling disease serum after hatching, 0.5 ml ~1 ml per gosling; goose paramyxovirus vaccine at 2 weeks of age, 0.3 ml ~0.5 ml per gosling; inactivated recombinant avian influenza virus vaccine at 2 weeks of age ~5 weeks of age, 0.5 ml per gosling; booster vaccination at 3 weeks after the first immunization, 1.5 ml per gosling; praziquantel 10 mg/kg body weight at 25 days of age; regular administration for disease prevention.
