Regulation and control of feeding environment of geese during nestling period

The rearing period of geese refers to the feeding stage from hatching to 4 weeks old, at this time, the regulation of feeding environment is the focus of the feeding and management of goslings, which directly affects the growth and development, survival rate and production performance of goslings. Seed goose is a small goose breed, the goslings are small, the adaptability to the environment is weak, and the growth and development is slow in the early stage. Therefore, it is of great significance to regulate and control the feeding environment scientifically according to the physiological characteristics of seed geese during the rearing period.

? Ambient temperature. Gosling is very sensitive to temperature, and high or low temperature is disadvantageous to the growth of goslings. High temperature, goslings are prone to respiratory diseases or colds; low temperature, easy to catch cold, resulting in indigestion or squeeze death, so the brooding stage should have special care, timely adjustment of brooding temperature. Because the seed goose is a small goose species, it has a weak ability to adapt to low temperature and sudden changes in temperature. Therefore, in the initial stage of brooding, the temperature is higher and the de-temperature speed is slower.

The appropriate environmental temperature for brooding is an important condition to promote the growth and development of goslings and improve the survival rate, and it is the comfortable temperature felt by the goslings themselves at this feeding stage, rather than the temperature reference value obtained by experience. Therefore, in actual breeding, more thermometers must be placed in the nursery, and the ambient temperature should be observed frequently. According to the specific behavior and health status of goslings to judge whether the temperature of brooding is appropriate or not. The specific judgment methods are as follows: when the temperature is suitable, the goslings distribute evenly, breathe peacefully and quietly, eat and eat normally, sleep quietly soon after eating, and the feces, growth and development are normal. Although goslings still like to lie down and rest together, there is no phenomenon of gathering and squeezing each other.

In brooding production, we still need to flexibly master some laws: the temperature can be higher at night and cloudy days, lower at noon and sunny days, higher in small groups, lower in large groups, higher in weak chicks and lower in strong chicks, and so on. After 21 days of age, when the cold protection ability of the goslings is enhanced and the temperature inside and outside the house is basically the same, the temperature can be gradually de-heated.

? Relative humidity. In production, the humidity in the nursery is required to be suitable. For example, if the humidity is too high, the pathogenic microorganism is easy to survive and reproduce, which leads to mold in the cushion, and the goslings are prone to many diseases such as white dysentery, coccidiosis, aspergillosis and colibacillosis; if the humidity is too low and the house is dry, it will accelerate the loss of water in the goslings, the villi are brittle, the toes are shriveled, and the goslings are prone to respiratory diseases.

At the age of 2 weeks, the goslings have strong metabolism, rapid growth and development, high temperature and easy dehydration. So the relative humidity should be 60%-70%. From 3 weeks to 4 weeks of age, the metabolic rate of goslings is accelerated, the activity is strong, and the excessive humidity hinders the heat emission of goslings, so the relative humidity should be about 65%.

There are many ways to control the humidity in the house, and the following four methods can be taken: one is to install a curtain on the ventilation window, which not only plays the role of ventilation, but also achieves the effect of moisture absorption and heat preservation; the second is to separate food and accommodation to avoid goslings from overturning the water in the drinking fountain, resulting in cushion moisture; the third is to change the bedding grass frequently, clean up the feces frequently, and keep the nursery dry at any time; fourth, quicklime can be used to absorb moisture.

The seed goose goslings should be reared in groups according to their physical strength and body weight, and the feeding density should be gradually reduced with the increase of age. It usually ranges from 20 to 25 per square meter from 1 day to 5 days, 15 to 20 per square meter from 6 to 10 days of age, 10 to 15 per square meter from 11 to 15 days of age, and 7 to 10 per square meter from 16 to 21 days of age. the density decreased gradually after 21 days of age.

? Reasonable lighting. Sunlight can increase the body temperature and appetite of goslings, facilitate digestion, accelerate metabolism, enhance the absorption of vitamin D, promote calcium and phosphorus metabolism, promote bone growth, and enhance disease resistance. If the light is strong and the time is long, the goslings can not get proper rest and are prone to pecking. The eyesight of newborn goslings is weak, and if the light is dim, it is not conducive to drinking and feeding. Artificial light should be used to make up for the lack of natural light at night to ensure that geese can exercise, eat and drink under appropriate intensity of light. to improve the production and development of goslings.
