In winter, the egg production of most laying hens will be reduced, and in the course of feeding and rearing, only finer, in order to ensure that the hens also maintain a higher egg production rate in the winter.
1. Properly arrange the egg laying peak at the peak of egg production around the 28th to 35th week of age, the egg production rate can generally reach 85% or more. During this period, the physiological performance of the layer chicken is the most vigorous and must be effectively used. period. To arrange the peak of egg production in winter, it is necessary to 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.
2. Maintain indoor conditions suitable for the environment to make laying hens 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°C. When the shepherd's temperature is less than 8°C, the egg production rate and the feed conversion rate are significantly reduced. The method of maintaining the indoor temperature is to keep the walls, doors, windows, and ceilings tight. The north side of the window is nailed with plastic sheeting to prevent cold winds from blowing in. It is also possible to increase the temperature by heating the stove or building a fire wall so that the temperature inside the home stays above 13°C. The second is the humidity. The relative humidity in the house should not exceed 60%. For this reason, the chicken manure under the cage should be frequently cleaned, and some stove ash is often used to absorb moisture. The third is ventilation. While emphasizing insulation, ventilation should not be neglected to ensure that the air in the house is fresh. At the sunny day, the south window is opened for 10 minutes to discharge dirty air.
3. Adjust the feed formula Winter cold, we must 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% of the formula are: corn 64%, bran 3.0%, 17.2% soybean cake, loquat powder 2.0%, fish meal 2.5%, 4.8% blood meal, bone meal 2.0%, shell powder 4.5% The formula has a crude protein content of 16.8%, metabolizable energy of 11.49 MJ/kg, calcium of 3.2%, phosphorus of 0.65%, crude protein content and metabolic energy are more suitable, feeding 3 or 4 times a day, feeding dry powder, drinking, and Shervin The same clean water, and pay attention to feeding grit. In winter, when chickens are fed with liquor at 60°C, 30 to 40 grams of liquor per kilogram of feed is mixed, the egg production rate can be increased by about 20%, and the disease resistance of chickens can also be enhanced.
4. The amount of drinking water in reasonable drinking hens is related to the temperature and the type of feed. In general, the amount of water consumed by the chicken when feeding dry material is about twice the amount of feed intake. If drinking water is not given for 36 hours, it will affect the egg production of the hen and even stop the production. Therefore, the drinking water of the laying hens must be guaranteed. Drinking warm water in the winter can prevent chickens from getting cold in the gastrointestinal tract and maintain body heat.
5. Satisfy the lighting requirements The breeding season light time generally needs to be kept around 8 hours every day. For the broiler chickens that are arranged during the peak of winter in the winter, they should pay attention to the lack of artificial light to supplement the natural light. At the age of 21 weeks, the light is extended for one hour each week, and when it reaches 26 weeks of age, the light is guaranteed for 14 hours every day. Practice has proved that laying hens can meet the needs of the peak period of egg production every day with 14 hours of light, and lighting must be switched on and off in time. Otherwise, it will disturb the response of chicken hens to light stimulation. Electric lights can be installed 1.8~2.0 from the ground. The height of the meter. The interval between the lamp and the lamp is equal, 40 watt bulbs, the lamp spacing is about 3 meters (if it is 1.5 meters should change 25 bulbs). A 40-watt incandescent bulb can be installed for every 18-20 square meters. Supplemental lighting should only be extended gradually and cannot be shortened.
