Safety management experience of goslings in spring

In large-scale production, the death rate of goslings aged 0-21 days is high, and the death rate caused by bad environmental conditions and unscientific management accounts for more than 60% of the total death rate of goslings.

The environmental factors that cause the death of goslings are as follows: temperature goslings are warm-blooded animals, but goslings are small, their down is thin, their thermoregulation is not perfect, and their adaptability to low temperature and sudden changes in temperature is very weak.

Goslings huddle in the low temperatures below 26 °C, and goslings that get into the huddle often die from asphyxiation. Artificial scatter crowd goslings, sweating goslings are easy to catch a cold, after people leave the goslings to pile up again, sweating. So repeated, not only the cold goslings increase, and goslings after many times sweating easy to cause hair, the formation of Zombie Goose.

Once the temperature of the Goose House exceeds 32 ° c, the goslings become depressed, eat less, drink more water, the body temperature rises and the body heat is blocked, which affects the growth and development and induces diseases. Long-term high temperature can also cause a large number of goslings to die.

The temperature requirement of raising goslings is suitable and balanced: The goslings from 0 Days to 7 days old should keep the room temperature at about 28 ° C, and then decrease by 2 ° c every week with the increase of their age, but the temperature difference between day and night should not exceed 2 ° C.

Humidity goslings on the requirements of environmental humidity can not be taken lightly. Practice has proved that when the humidity is more than 80% , accompanied by temperature discomfort, goslings that the spirit, loss of appetite, piling, breathing difficulties, diarrhea, fluffy and other symptoms. Such goslings are mostly stunted, vitality, disease resistance weakened, the future is easy to become stiff goose, lost feeding value. In the high temperature and humidity environment, pathogenic microorganisms and parasites are easy to breed, fodder and bedding are easy to mildew, the incidence of goose flock is also increased, but also lead to goslings of heat stroke.

Hunger and lack of water with the body of the remaining yolk is gradually absorbed, goslings metabolism increasingly vigorous. Because of the small gastrointestinal volume of Goslings, poor digestion, so the requirements for the supply of feed quality, easy to Digest. In the feeding process to be reasonable grouping, feed trough or plate size, height should be appropriate, place to be appropriate, to ensure that each goslings can eat well, eat moderate. The body of the newly hatched goslings contains about 75% water. If the goslings are not given water within 24 hours, the goslings will quickly show symptoms of depression, drooping wings, lethargy, eyeball sunken and local skin shrinkage due to severe dehydration. Therefore, it is more important for the young to be given clean, warm water at an early age than to be fed, and once they start drinking, they can not be interrupted without reason.

Goslings are very sensitive to harmful gases such as carbon dioxide, ammonia and hydrogen sulfide in the Brood Room. When the level of carbon dioxide in the environment exceeds 0.51 mg/kg, the level of ammonia exceeds 21 mg/kg and the level of hydrogen sulfide exceeds 0.46 mg/kg, gOSLINGS will appear depressed, breathing faster, oral mucus increase, loss of appetite, feather Pine Disorder Without Luster and other symptoms. If the harmful gas continues to accumulate, goslings will appear corneal OPACIFICATION, eyelid edema, tears, runny nose, and loss of appetite, and movement disorders and other neurological symptoms, * * Back head, seizures, paralysis and death. The main causes of CO2 poisoning in goslings are high room temperature, poor ventilation in the nursery and high density of goslings. The main causes of ammonia and hydrogen sulfide poisoning in goslings were damp Brood House, poor ventilation, unclean bedding and feces, etc. .

Drug poisoning due to multi-drug, drug abuse caused by goslings poisoning casualties in the process of goose is very common. The main reason is the lack of modern feeding concept, the blind use of Nitrofurans (such as Furazolidone) , antibiotics, sulfonamide, etc. from the time the goslings start to eat, causing acute or cumulative drug poisoning. Geese are herbivorous waterfowl with unique biological and physiological characteristics. As people used to long-term traditional rough feeding, geese are more sensitive to drugs, especially goslings.

The practice has proved that as long as the Brood Environment is clean, hygienic and dry, the temperature, humidity, light and feeding density are suitable, the individual groups are reasonable, the ventilation and ventilation are good, and the fresh and clean feed and drinking water are regularly and quantitatively fed, gOSLINGS can grow up healthily and are less susceptible to common and parasitic diseases. As for goslings plague, goslings new type viral enteritis, goose paramyxovirus disease and other infectious diseases, it is useless to prevent and cure them with drugs.

Only by regularly immunizing goslings and goslings according to the prescribed immunization procedure can the disease be avoided, ensure production safety. The death of goslings is often caused by the bad heat preservation condition of the brood room, the scare of Goslings, the bump of goslings in the process of shipping, the irregular feeding and drinking, and the high feeding density.
