After the autumn, the sun gradually reduced, the weather turned cold, adult hens began to stop moulting, new laying hens gradually laid eggs, the following feeding management techniques can be used to increase efficiency.
1. After the new chicken has started its production, it will be laid in spring. But at this time, the nutrients eaten by the new chickens are partly used for egg production and some are used for the growth and development of the body. Therefore, to increase the egg production of new chickens, it is necessary to provide feeds rich in nutrients for artificial oxytocin production. Oxygen production method: When every 100 new laying hens produce 5 to 10 eggs per day, add 7.5 to 25 kg of soybean meal, 2.5 to 5 kg of fish meal and blood meal, 250 g of salt, and poultry in 50 kg of feed. 5 grams of bran, 2.5 to 5 kg of bran, 1.5 kg of eucalyptus leaf powder, 2.5 kg of bone meal, and 2 to 2.5 kg of shell powder, and the rest supplemented with 50 kg of corn. After about 45 days of oxytocin production, when the number of eggs produced per 100 chickens per day reaches 0 to 87, fishmeal or 0.5 to 1.5 kg of blood meal and 0.5 to 1.5 kg of bean cake are added to every 50 kg of feed, and bran is appropriately reduced. Or the amount of corn, to increase the duration of work light. Some chickens were found to have lost weight, and corn consumption was appropriately increased. After oxytocin production, generally, each chicken can produce 20 to 40 eggs in the fall.
2, adjust the chickens will be low-yield chickens, stop production chickens, weak chickens, chickens, chickens with severe paralysis, chickens with short egg production time, overweight or overweight chickens, chickens with no value in time It will be eliminated, leaving chickens with good production performance, robust physique, and normal egg production.
3. The standard body weight determines the production performance of the hens. The broiler households should try to achieve a standard weight for the primaries and hens. If you do not pay attention to the energy requirements of chickens and you weigh less when you start production, it is very difficult for chickens to reach the egg production rate at the peak of standard laying. If the weight is not up to the standard during the peak period, there will be a one-time drop in egg production rate. As the duration of maintenance is shortened, premature death of laying hens can occur.
4. Mandatory moulting. Winter moulting of laying hens can be suspended for up to 4 months. During the moulting period, the number of eggs laid by the chicken is greatly reduced, and the moulting time is sooner or later. After the moulting, there is also the first time after the moult. The peak period of egg production is late, causing inconvenience to the husbandry and management. Therefore, it must be artificial. Forced moulting, prompting the laying hens to moult simultaneously while opening production. Artificial forced moulting can use the following methods. Add 2.5% zinc oxide or 4% zinc sulfate to the layer diet. After zinc oxide or zinc sulfate was added, the appetite, feed intake, body weight, and egg production rate of laying hens were all decreased. The feed intake decreased to about 20 g after 2~3 days, and the egg production rate decreased by 75% on the 4th day. 80%, to the seventh day, the egg production rate is almost zero. High-zinc diets continue to feed for 7 to 8 days, and the weight of chickens will decrease by about 25%. If the weight loss is less than 25%, you can continue to feed high-zinc diets. When the weight of the chicken group drops by 25%, after the chickens are discontinued, zinc oxide or zinc sulfate is to be removed, and the early feed of the layer is changed. On the first day, 30 to 40 grams of each chicken is fed and then increased by 10 grams per day. 100 grams can be eaten freely. Note that there is no need to stop the water during the feeding of high-zinc diets, and the light can be reduced to 6-8 hours per day, and gradually increase the number of hours of illumination to 16 hours per day after returning to normal feeding.
5. Feeding Additives Adding some additives in the hen's diet during the winter to increase the energy content of the feed can increase chicken egg production, anti-stress and disease resistance, and can save feed. The commonly used additives are: 1 egg additives, will stir the eggs in the proportion of 0.25% evenly into the feed, any chicken free to eat, can increase egg production rate, and can enhance immunity; 2 vitamin C, in Adding 500 grams of vitamin C per kilogram of diets.
