Due to climatic reasons, laying hens in winter have different degrees of decline in egg production, and the price of eggs in winter is relatively high. Therefore, raising the chicken egg production rate in winter is of vital importance to raise the economic benefit of raising chickens. Should do five things:
Firstly, we must reasonably arrange the peak period of laying hens laying at 28 to 35 weeks of age, and the egg production rate can reach 85% or more. During this period, the laying hens have the best physiology, and they must use this effectively. During a precious period, when the peak of egg production is arranged in the winter, we must change the early spring brooding to brooding in May and June. At this time, the temperature gradually rises, the survival rate of brooding is high, and the peak period of egg production is just in winter.
Second, to maintain a suitable indoor environment only to create a suitable environment for chickens, in order to make it have a higher egg production rate in the winter. The first is the temperature. The most suitable ambient temperature for laying hens is 13-21 degrees. The egg production rate and feed conversion ratio are significantly reduced when the shenwen temperature is less than 8 degrees. The way to maintain the indoor temperature is to keep the walls, doors, windows and ceilings tight. The north side of the window is nailed with plastic sheeting, which is blown into the cold wind; it can also be heated in the furnace or fire wall to keep the temperature within 13 degrees, and the second is the humidity, and the relative humidity in the room should not be More than 60%, to this end should often clean the Cage chicken manure, often put some dust to absorb moisture. The third is ventilation. When emphasizing moisture, we must not neglect the ventilation and ensure that the air in the house is fresh. At the sunny day, we open the south window for 10 minutes to discharge the polluted air.
Third, we must adjust the formula of feed in cold winter weather, we must appropriately increase the proportion of energy feed, but also according to the different laying rate of laying hens timely adjustment of feed formulations to meet the production needs, suitable for winter use egg production rate of about 80% The formulas are: corn 64%, bran 3.0%, bean cake 17.2%, loquat leaf powder 2.0%, fish meal 2.5%, blood meal 4.8%, bone meal 2.0%, shell powder 4.5%, the formula crude protein content 16.8%, metabolizable energy 11.49 megajoule/kg, calcium 3.2%, phosphorus 0.65%, eggs can be more appropriate, feeding 3 or 4 times a day, feeding dry powder, drinking the same clean water as Shewh, and pay attention to feeding grit.
Fourth, we must reasonably drink a good amount of water in laying hens and the temperature, the type of feed: In general, the amount of water consumed by the chicken when fed with dry material is about twice the amount of feed intake. If it does not give drinking water for 36 hours, it will affect The egg production of the hens is stopped until they are produced, thus ensuring the drinking of the laying hens. Drinking warm water in the winter can prevent chickens from getting cold in the gastrointestinal tract and maintain body heat.
Fifth, to meet the lighting requirements during the breeding period, the lighting time is generally maintained at about 8 hours per day. For the broiler chickens that are arranged at the peak of the laying season in the winter, attention should be paid to supplementing the natural lighting with artificial light in the later period. At 21 weeks of age, the light is extended for one hour per week, and the light is guaranteed for 14 hours per day when it reaches 26 weeks of age. It has been proved that the layer of eggs can meet the needs of the peak period of egg production every day with 14 hours of light, and the light must be switched on and off in time when it is filled with light. Otherwise, it will disturb the response of the layer to the formation of light stimulation. The light can be installed on the ground 1.8- 2.0 meters in height. The distance between the lamp and the lamp is equal, 40 watt bulbs, the lamp spacing is about 3 meters (if 1.5 meters should replace 25 lamp). Each area of ​​18-20 square meters can be loaded with only 40 watts. Supplemental lighting should only be extended gradually and cannot be shortened.
