9-step autumn chickens
After the autumn, the sunshine is gradually shortened, the weather turns cold, adult hens cease production and moulting, new laying hens gradually produce eggs, the following feeding management techniques can be used to increase efficiency.
1. After the new chicken has started production, the spring-fed laying hens are about to lay eggs. 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 5 new laying hens produce 5 to 10 eggs per day, mix 7.5 to 25 kg of bean cake, 2.5 to 5 kg of fish meal and blood meal, 250 g of salt, and poultry in each 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 reaches 0 to 87 per day, fishmeal or 0.5 to 1.5 kg of blood meal and 0.5 to 1.5 kg of bean cake are added to each 50 kg 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 oxyster production, generally, each chicken can produce 20 to 40 eggs in the fall.
2. Adjust the chickens to produce low-yielding chickens, discontinued chickens, weak chickens, frozen chickens, chickens with severe parasites, chickens with short egg laying times, overweight or overweight chickens, and disease-free chickens 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 performance of the hens. The broilers should try to make the primaries and hens reach the standard weight. 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. Compulsive moulting In the fall, the adult laying hens have to stop moulting 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 all decreased. After 2 to 3 days, the feed intake decreased to about 20 grams, and by the fourth day, the egg production rate decreased by 75%. 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 the chickens will decrease by about 25%. If the weight loss is less than 25%, you can continue to feed high-zinc diets. When the chicken group weight drops by 25%, after the chickens are discontinued, zinc oxide or zinc sulfate is to be removed, and the early feed of laying hens is changed. On the first day, each chicken feeds 30-40 grams, and then increases 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. 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. Feed additives Adding some additives in the diet of laying hens in the fall 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.
6. During the peak egg production of light-laying hens, it takes 16 to 17 hours of light each day. After the fall, the natural light hours gradually decrease, and light should be supplemented appropriately. When supplementing light, the light intensity is preferably 3 watts per square meter. Turn on the light twice a day, turn on the light for the first time from 4 to 5 o'clock in the morning, turn off the light until dawn, and turn off the light when the light turns on for the second time when it is dark. In the event of cloudy weather, the lights must be turned on during the day. Pay attention to the regularity of artificial supplementary lighting, turn on the lights on time, turn off the lights on time and persevere.
7. Insect repellents New chickens in the fall are in the open period, the old chickens are in the moulting period, and the new and old chickens are in the low tide period of egg production. This is the best period for deworming, and there is no big impact on egg production. The following medicines can be selected for deworming: 1 levamisole hydrochloride, 20 grams of medicine per kilogram of feed and drinking water, let the chicken eat and drink freely, 2 to 3 times a day, feed 3 to 5 days; 2 Spirit, 0.2-0.25g per kilogram of body weight, used in materials or directly fed; 3 insects and nemesis, each with 50kg of body weight and 0.2g of insecticide powder 5g, oral administration, irrigation or uniform Stir in feed and feed; 4 compound enemies net, mix by 0.02% feed, mix for 3 to 5 days; 5 ammonia propriofen, mix in feed or drinking water by 0.025%, use 3 to 5 days, give chicken drive During the period of insects, chicken manure should be promptly removed and the chicken house and utensils must be thoroughly disinfected.
8. Disinfection and epidemic prevention The temperature in autumn is suitable. The pathogenic microorganisms multiply, and the chicken is susceptible to various diseases. The sanitation of the chicken house should be improved and the disinfection should be carried out regularly. The chicken house walls, floors, and utensils should be regularly sterilized with 2% to 3% caustic soda solution or 2% to 4% of lesuole solution or 0.2% to 0.5% peroxyacetic acid solution, or 0.1% benzalkonium bromide solution disinfection. It is necessary to do a good job of prevention and epidemic work, injecting chickens with Newcastle disease I, chicken cholera, infectious laryngopharyngitis and other vaccines, and prevent all stress factors from occurring.
9. Prevent stress In autumn, when the weather is cold from heat, when the ventilation and body temperature are seriously out of balance, the chickens will suffer from cold and heat stress, and environmental stress (ventilation) will cause changes in the laying cycle. Therefore, chicken farmers should make preparations in advance to keep the sheds and the surrounding environment quiet, minimize stress factors such as startle, group migration, and catching chickens, prevent cats and dogs from entering the henhouse and scare the chickens and reduce ventilation. Contradictions with insulation, feed processing, loading and unloading should be far away from the chicken.
