Spring is not only an important time for the growth and development of poultry, but also a time when the temperature is changeable and the epidemic is high. At this time, the feeding and management are particularly important.
The warm and airy spring weather is cold and changeable, which brings a lot of inconvenience to the chicken production. In particular, the large temperature difference between day and night has a significant impact on laying hens. The temperature of the house should be controlled during this season so that the temperature difference between day and night should not exceed 5°C. While maintaining warmth, we must also pay attention to ventilation. In the spring, due to the low temperature, the doors and windows of the chicken house are closed and ventilation is reduced. However, the harmful gases such as ammonia gas, carbon dioxide and hydrogen sulfide produced by chicken exhaust gas and chicken manure still exist. When the air in the house is dirty, it is easy to induce diseases such as the respiratory tract of the chicken. Therefore, farmers need to deal with the relationship between ventilation and warmth, and timely remove fecal matter and debris from the house. When the weather is good at noon, open windows for ventilation, so that the air in the house is fresh and the oxygen is sufficient.
Reducing humidity In spring, the house has less ventilation and less water evaporation, resulting in excessive moisture in the house, creating conditions for large numbers of bacteria and parasites. Therefore, farmers need to strengthen management and guard against bacterial diseases, parasitic diseases, etc., so as to avoid unnecessary losses. It is possible to add “Yiwei Liwei†for a long time, adjust the balance of chicken intestinal flora, increase the feed conversion rate, and reduce The incidence of intestinal diseases.
Supplementary lighting early spring night is short, long-term due to lack of light will cause egg production rate of laying hens can be artificially supplemented by light to compensate. In general, the total daily light exposure should not be less than 14 hours or 17 hours. The supplemental lighting is divided into two ways: fill light and segment fill light. Fill light once, that is, make up the required light at one time in the morning before dawn or at night after dark. Stage fill light, that is, the insufficient illumination time is divided into two supplies in the morning and evening. Under normal circumstances, the supplemental artificial light intensity is preferably 2 to 4 watts of light per square meter.
Modified soybean phospholipid refers to a type of phospholipid that has been altered or processed in some way to improve its functionality or suitability for various applications. This can include changes to the chemical composition, molecular structure, or physical properties of the phospholipid.
