Five measures for high production of laying hens in winter

Five measures for high production of laying hens in winter

The peak laying period of laying hens at the peak of egg production is reasonably arranged at about 28 to 35 weeks of age. At this time, the laying rate is generally above 85%, and the physiological function of laying eggs is the most vigorous. This period must be used effectively. In order to arrange the peak period of egg production in the winter, it is necessary to change the early spring brooding to brooding from May to June, when the temperature gradually rises, the survival rate of brooding is high, and the peak period of egg production is just in winter. Keeping the proper environment in the house can only create a suitable environment for the chicken to make it have a higher egg production rate in winter. The first is temperature. The most suitable ambient temperature for laying hens is between 13°C and 21°C. When the shepherding temperature is below 8°C, the egg production rate and feed conversion rate are significantly reduced. Ways to maintain indoor temperature include: walls, doors and windows, ceilings should be kept tight, plastic windows should be nailed to the north to prevent winds from blowing in, and furnaces or walls can be added to increase the temperature in the house so that the temperature inside the house can be maintained at 13. °C or more. Followed by humidity. The relative humidity in the house should not exceed 60%. For this reason, chicken manure under the cage should be regularly cleaned and some ash should be laid to absorb moisture. Again ventilation. While emphasizing insulation and moisturizing, it is also necessary to pay attention to ventilation and ventilation to keep the air in the house clean. At noon on a sunny day, the south window can be opened for 10 minutes to discharge dirty air. Adjust feed formulas Winter cold weather, to properly increase the proportion of energy feed, but also adjust the feed formula according to egg production rate to meet the needs of laying hens. Suitable for winter use, the egg production rate is about 80% of the formula is: corn 64.0%, 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%, and phosphorus of 0.6%. Feed 3 to 4 times a day, feed dry powder, drink clean water at the same temperature as Shev, and pay attention to feeding grit. The drinking capacity of reasonable drinking hens is related to the temperature and feed type. In general, when feeding dry materials, the amount of water consumed by the chicken is about twice the amount of feed intake. If drinking water for 36 consecutive hours does not affect the production of eggs or even stop production, it is necessary to ensure the drinking water of laying hens. In the winter, clean and warm water should be given to prevent chickens from getting cold and getting sick. It is also good for maintaining body temperature. To meet the lighting requirements during the breeding period, the lighting time should be maintained at about 8 hours per day. For the broiler chickens that are scheduled for the peak of the laying season in the winter, artificial lighting should be added later. At the age of 21 weeks, the light is extended for one hour each week, and the daily light time at 26 weeks is 14 hours. Practice has proved that laying hens have 14 hours of light each day to meet the needs of the peak period of egg production. When replenishing, it is necessary to switch light on time. Otherwise, it will disturb the response of the hens to light stimulation. The lamp installation height is 1.8m to 2.0m from the ground, and the 40W bulb has a lamp spacing of about 3m (if it is 1.5m, a 25W bulb should be replaced), and a 40W bulb per 18m2 to 20m2 is installed.
