The geese brooding period refers to the feeding period from hatching to 4 weeks of age. At this time, the regulation of the feeding environment is the focus of the breeding gosling management, which directly affects the growth and development, survival rate, and production performance of the goslings. Goose is a small goose species, small individual goslings, less adaptable to the environment, early growth and development. Therefore, according to the physiological characteristics of the geese brooding period, it is of great significance to carry out the scientific regulation of the feeding environment.
Ambient temperature. The response of the goslings to temperature is very sensitive, and high or low temperatures are not conducive to the growth of goslings. High temperatures, goslings susceptible to respiratory diseases or colds; low temperature, easy to cold, leading to indigestion or squeezing death, so brooding stage must have special care, timely adjustment of brooding temperature. Because the goose is a small goose species, its adaptability to sudden change of temperature and temperature is weak. Therefore, at the early stage of brooding, the temperature is higher and the rate of degassing is slower.
The suitable brooding environment temperature is an important condition for promoting the growth and development of goslings and raising the survival rate. It is the comfort temperature felt by the gosling itself during this feeding period, rather than the empirically determined temperature reference value. Therefore, the actual breeding must put a thermometer in the brooding house, and often observe the ambient temperature. Through the specific behavior of the goslings and health conditions to determine the appropriate temperature for brooding. The specific judgment method is: When the temperature is suitable, the goslings are evenly distributed, the breathing is calm, quiet, appetite, feeding is normal, and after sleeping, the sleeping is quiet, and the feces and growth are normal. Although goslings still have the habit of lying and resting together, there is no phenomenon of gathering and squeezing each other.
In brooding production, some laws need to be flexibly controlled. The temperature at night and on cloudy days can be higher. At noon and on sunny days, it can be lower; the small group can be higher, the large group can be lower; the weak brood can be higher, and the young can be lower Wait. After 21 days of age, when the gosling’s ability to keep warm is enhanced and the temperature inside and outside the house is basically the same, it can gradually de-warm.
Relative humidity. In production, it is required that the humidity in the brooding house is suitable. If the humidity is too high, the pathogenic microorganisms are likely to survive and multiply, causing litters to appear moldy, goslings that are susceptible to white feathers, coccidiosis, aspergillosis, and E. coli diseases; humidity is too low and drying in the house will accelerate Loss of water in the body of goslings, fragile hair, dry toes, and goslings susceptible to respiratory diseases.
Goose geese have a strong metabolism, fast growth, and require high temperature and easy dehydration within 2 weeks of age. So the relative humidity should be 60%~70%. From 3 weeks to 4 weeks of age, the speed of metabolism of the goslings is accelerated, and the activity is strong. If the humidity exceeds the limit, the body temperature of the goslings is hindered. Therefore, the relative humidity should be about 65%.
There are many ways to control indoor humidity. The following four methods can be used: The first is to install a curtain on the ventilation and ventilation window, which not only plays the role of ventilation, but also achieves the effect of moisture absorption and insulation. Second, the food and accommodation are separated. Avoid goslings to overturn the water in the drinking fountains, resulting in the weeding of the grass. Third, change the bedding, diligently clean the waste, and keep the brooding room dry at any time. Fourth, you can use quicklime to absorb moisture.
Goose goslings should be reared in groups according to their physical strength and body weight, and gradually reduce their rearing density as they grow older. Usually 1 to 5 days of age is 20 to 25/sq.m, 6 to 10 days of age are 15 to 20/sq.m, and 11 to 15 days of age are 10 to 15/sq. m, from 16 to 21 days old, 7 to 10 per square meter, and the density gradually decreased after 21 days of age.
Reasonable lighting. Sunlight can increase the body temperature and appetite of goslings, facilitate digestion, speed up metabolism, increase the absorption of vitamin D, promote calcium and phosphorus metabolism, promote bone growth, and enhance the body's resistance to disease. If the light is strong and the time is long, the goslings are not properly rested, and they are susceptible to worry. Newborn goslings have poor eyesight. If the light is dim, it is not conducive to drinking and feeding. At night, artificial light should be used to make up for the lack of natural light. This ensures that the geese can exercise, eat, drink, and drink water under appropriate intensity. Goose production growth rate.
