In winter, the temperature is low, and the sunshine duration is short. The egg production of laying hens is obviously reduced, and some even stop production. So, how to make laying hens produce more eggs in winter?
Insulation ventilation
The temperature in the winter house must be kept above 5°C. The chickens should be put in early and late; lay 5-6 cm thick rice husks or sawdust on the ground; allow the chickens to drink warm water when conditions permit; and clear the snow on the sports field after snowing. Ventilation holes are required at the top of the house, and ventilation and ventilation are frequently performed to prevent harmful gases from harming the flock.
Increase lighting
Increased light in winter can promote the secretion of hormones in the anterior pituitary of laying hens, thereby increasing egg production. Therefore, ensure that the layer of chickens has 14 to 16 hours of light per day. The methods of supplementing light include light in the morning, light in the evening, and light in the morning and evening. In general, a 20 to 24 square meter chicken house can be equipped with a 10 to 60 watt incandescent lamp. The light intensity must be stable and cannot be changed at will.
Enhanced feeding
In winter, the metabolic energy content in the diet should be increased, and the protein/energy ratio should be appropriately reduced. Therefore, you can feed more corn. Because there are fewer green and green vegetables in winter, carrots and multivitamin additives should be supplemented to prevent the lack of vitamins and affect egg production. In addition, for some layer chickens of different ages, adding some irritating substances in the feed can also increase the egg production rate. According to reports, laying hens aged 150-200 days add 55-60 grams of succinic acid for every 10 kilograms of bran feed; layer chickens over 340 days of age add 3.5-4 lbs for every 10 kilograms of bran feed. Vitamin B2 and 25-30 grams of vitamin B12 can increase chicken egg production by about 11%.
Strengthen sports
It is advisable to sprinkle some grains on the mat grass or suspend the green vegetables in the chicken house. The height of the hanging vegetables should be 3 to 4 cm higher than the level reached by the hen's crotch. It should not be too high to encourage the flock to move.
In addition, the manure in the house should be frequently cleaned and kept dry; every morning, it should be disinfected with 2% of leprosy.
