1, warm
In the early spring, the air was unstable, the green feed was scarce, and the climate was cold and changeable. This caused many inconveniences to the chicken production. In particular, the effect of low temperature on laying hens was obvious. Therefore, under normal circumstances, we can take appropriate increase in breeding density, and close the doors and windows, add straw, drinking warm water and stove heating and other ways to keep cold insulation, so that the minimum temperature maintained at 3 °C ~ 5 °C.
2, ventilation
In early spring, due to the low temperature, the doors and windows of the chicken house are closed and the ventilation is reduced. However, harmful gases such as ammonia gas, carbon dioxide, and hydrogen sulfide generated from the chicken exhaust gas and chicken manure accumulation will accumulate in the chicken house, and it is easy to induce the respiratory tract of the chicken. Other diseases. Therefore, the early spring chickens should effectively handle the relationship between ventilation and warmth, timely removal of feces and debris in the house to ensure clean air. When the weather is good at noon, the windows should be ventilated so that the air in the house is fresh and the oxygen is sufficient to prevent the problem. However, be careful when ventilating. Do not blow cold air directly on the chicken to prevent the chicken from catching a cold.
3, humidity
In the early spring chicken house, the ventilation is small and the evaporation of water is reduced. In addition, the hot air in the house will be exposed to the cold roof and the wall will condense into a large amount of water droplets, causing excessive moisture in the house and creating a large number of bacteria and parasites. Conditions. Therefore, early spring must strengthen management, pay attention to keep the chicken house clean and dry, timely repair of damaged sinks, avoid excessive overfilling with water, is strictly prohibited to splash water on the floor.
4, disinfection
Disinfection work should be carried out throughout the entire process of raising chickens. The temperature in early spring is relatively low, and the frequency of bacterial activity has declined. However, the climate in the early spring was cold and the resistance of chickens was generally weakened. If you ignore the disinfection, it can easily lead to outbreaks of the disease and cause heavy losses. Therefore, in early spring, we must do a good job of disinfection and regular disinfection.
5, fill photos
Illumination is the driving force of all life activities. In early spring, long nights, laying hens often cause lack of light and cause egg production rate to decline. In order to overcome this natural defect, artificial supplemental lighting can be used to make up for it. In general, the total time of daylight should not be less than 14 hours, but it should not exceed 17 hours (more than 17 hours will cause chicken physiology disorders). For example, the natural daytime light is 12 hours, and it is necessary to artificially supplement light for 2 hours to 5 hours every day.
6, increase energy
Chickens rely on the energy feed they eat to obtain heat to maintain body temperature. The lower the ambient temperature in the early spring, the more heat energy the chickens use to protect the cold. It has been determined that the consumption of feed for early spring chickens is about 10% higher than that of other seasons. Therefore, in early spring chicken feed must ensure adequate energy feed, in addition to ensuring a certain percentage of protein, but also should be appropriate to increase the high-energy feed containing starch and sugar, in order to meet the chicken's physiological and production needs.
7, strong body
The resistance of chickens in early spring declines, and special attention must be paid to the prevention of epidemics and regular immunizations. According to the actual situation, some preventive drugs can be regularly targeted, and the content of Vitamins and trace elements in feeds can be appropriately increased, the constitution of chickens can be enhanced, the ability of chickens to prevent diseases and production capacity can be improved, and the aquaculture efficiency can be improved.

(Hepatprotective meaning liver/blood protector. Gaba receptor cells uptake alcohol during consumption and the resulting loss of function from loss of GABA uptake produces the effects of intoxication.) Milk Thistle Extract can protects the liver by promoting the growth of new liver cells.
