The breeding of laying hens needs to follow scientific methods. According to their physiological characteristics and growth and development law, the breeding management should be conducted in different stages, and comfortable ambient temperature, humidity and light should be provided at different stages. In addition, the breeding density should be kept reasonable with the increase of age.At the same time, the feed nutrition was adjusted at any time and the feed was fed regularly and quantitatively to meet the needs of the feed nutrition of laying hens at different growth stages, so that the growth and production performance of laying hens were well developed.1, brood stage of feeding management 1.1 brood stage, often referred to as laying hens at the stage of 0 ~ 42 days, at this stage, just start hatching chicks growth and development, a variety of body function is not yet perfect, need to be careful breeding management, especially in the aspects such as temperature, humidity and breeding density must meet the needs of the chicks to environmental conditions, and adjust in time,In order to effectively improve the survival rate of chicks, for the future good development and improve the production performance to lay a foundation.In the feeding, due to the small size of chicks, can be relatively high feeding density, the recommended feeding density of 1~3 weeks of age is 50~60 /㎡, 4~6 weeks of age 20~30 /㎡.In feeding, according to the strength of the chick’s body, group feeding, in order to improve the survival rate of weak chicks.Chicks just out of the shell have not perfect temperature regulation function, and their feed intake is small, easy to heat and afraid of cold, so they need a higher temperature, which needs to give them a suitable environmental temperature.Generally, the ambient temperature of 1-day-old chicks is 35℃, and then the ambient temperature is gradually reduced by 1℃ every 4 to 5 days to ensure that the ambient temperature of the chickens drops to 20 to 22℃ before 42 days of age.While lowering the temperature, we should pay attention to the observation of the chickens. If the chickens appear asthma and other conditions, the temperature is too high, and if the chickens appear in clusters, the temperature is too low.The adjustment of temperature also needs to be combined with the actual situation. If the chicks are physically strong, the cooling range can be appropriately increased; otherwise, the cooling range should be slowed down.While paying attention to temperature control, humidity should be adjusted at the same time. Chickens within 2 weeks of age have higher requirements for external humidity, and the humidity of the chicken house should be in the range of 60% to 70%, while the humidity of chickens after 2 weeks of age should be reduced to 55%-60%.In order to ensure the temperature and humidity on the basis of ventilation, ventilation can discharge harmful gases, but the requirements of ventilation does not affect the temperature and humidity, for chicks, insulation and moisture is more important.Chicks are exposed to light for an initial 24 hours after birth, and gradually reduce exposure as they grow, to no more than 8 to 12 hours at 6 weeks of age.Then the chicks were divided into two groups, usually at 4 weeks and 8 weeks of age, and reared according to the quality of the chicken population.Beaks should be debeaked when chickens are between 7 and 11 days old.1.2 Feeding in good management at the same time to carry out scientific feeding, chicks should be given drinking water as early as possible, the temperature of drinking water should be appropriate, using warm water feeding, if in the hot season can be appropriate to reduce the temperature of drinking water, in the cold season should be appropriate to improve the temperature of drinking water.Within 1 week after hatching, some vitamins and minerals should be added to the water, such as electrolytic multidimensional, biotin, etc., while adding some sugar to promote the drinking water of chicks.This can improve the survival rate of chicks.Need to clean the drinking water system in time every day to ensure clean drinking water, otherwise it will increase the chance of microbial reproduction, and then increase the risk of infection of chicks, add drinking water at any time, ensure adequate drinking water, is conducive to improving the absorption and digestion ability of chicks to feed.2.1 Management The rearing period usually refers to the period from 43 to 130 days of age of chicks. During this period, the main task is to improve the survival rate of laying hens, improve the uniformity, and lay a good foundation for laying eggs.This is an important time for the flock to achieve good weight and body function in preparation for egg laying.During this period, the population temperature regulation ability of chickens has been perfected, and the requirements for temperature are not high, as long as the ambient temperature is maintained at 15~22℃.The humidity is required to reach 50%~60%, and the feeding density should be adjusted, usually using the way of flat raising, the density is not more than 15 /㎡, and the way of cage raising is not more than 25/㎡.Illumination time should also be gradually reduced to eight hours, maintain to 16 weeks of age, so that to ensure the sensitivity of chickens to illumination, if use the light for a long period of time, chickens began in late bred sexual development, will be stimulating mature early, although able to open early, but will affect the whole period of egg production performance, so that the incubation period of light management is very important,It is best to keep the chicken coop in an airtight condition, so it is easier to maintain a constant 8 hours of light.During this period, the chickens with poor probeaks should be debeaked again, usually at 18 to 20 weeks of age.2.2 Feeding At this stage, the weight of chickens should be strictly controlled. Sampling inspection should be carried out every week with reference to the weight index of chickens, and the sampling inspection proportion should be 5%-10%, depending on the size of chickens.When the weight of more than 85% of the chickens in the whole flock can reach the standard, the weight of the chickens in the whole flock can reach the standard.Otherwise, the feed limit should be changed according to whether the weight of the flock is too light or too heavy to promote the weight of the flock to meet the standard.In the process of weighing, must abide by the principle of timing, fixed-point, quantitative and a person, also is in a fixed time every week to extract fixed location of chicken said only weight, and said enough, staff involved in the weighing should be fixed, so as to ensure the accuracy of the sampling, otherwise it will provide management with wrong data, and affect the next phase of the feeding amount,Thus, it is not conducive to the increase of population weight and the development of sexual organs.Egg production should also be controlled during breeding, usually 50% by the time the flock reaches 150 days of age.The laying rate should not be reached too early, otherwise the performance of laying period will be affected. The adjustment of laying rate can be controlled by the nutrient level of feed and light time.Before moving on to the next stage, the flock is screened to remove abnormal growth and disabilities.3. Feeding and management of laying period Laying period refers to the period after the chickens grow to 130 days of age.The egg-laying period is usually divided into the first perinatal period, high yield period and late egg-laying period.3.1 The period of initial perinatal period refers to the period from 130 to 223 days of age.This stage is a critical period for laying hens. Laying hens change from never laying to laying. This transition will make the hens not adapt to it, and the eggs produced at first are small, and there are more deformed eggs.It is necessary to add some Chinese herbal medicine in the feed to clear heat and detoxify it or add some broad-spectrum antibiotic drugs to prevent the occurrence of salpingitis, such as Shuangniu oral liquid, Lotus Jieqing, oguan Kang, vitality zengomin, etc., to avoid the death of chickens caused by improper feeding and management.With the increase of egg production, the nutrient level of feed should be adjusted appropriately or the feeding amount should be increased appropriately to meet the needs of feeding nutrition of chickens.Even replace high-yield feed, in the process of changing feed must be gradually transition, to avoid all kinds of stress, otherwise it is easy to cause dyspepsia diarrhea of laying hens and reduce the increase of laying rate.3.2 In this stage of high yield, the egg production rate is the highest, reaching more than 85%, so feeding management should be strengthened.At this stage, attention should be paid to avoid all kinds of stress on the hens, ensure that the hens are in a relatively constant environment, and can not cut off water and feed to the hens. The hens should be fed regularly and quantitatively, and drinking water should be added at any time to ensure adequate drinking water and feed to meet the needs of the hens for nutrition and drinking water.Also pay attention to ambient temperature and humidity and ventilation.The level of some nutrients in the feed should be increased, usually the protein level should be increased by 5%, and the content of calcium and phosphorus should also be increased by 3 to 4 times.At the same time to add fat soluble vitamins, to avoid vitamin deficiency, at the same time in order to prolong the egg production period, mix materials or drinking water to add eggs 360 ⅱ generation, enhance the ability to resist stress, so that productive eggs at the peak of egg production.3.3 Late stage of laying When laying hens grow for more than one year, they reach the late stage of laying, during which the laying rate drops significantly, even to below 80%. At this time, the laying performance of laying hens decreases. If the hens are fed according to the feed of the peak period, it will lead to excess nutrition of laying hens, resulting in excessive fat of laying hens.In the late stage of laying, feeding amount should be reduced according to the weight of laying hens, laying rate and feeding time, so as to meet the needs of laying hens and prevent excessive fat deposition from affecting laying rate.At this time to carry out selection, to ensure that the egg production rate of about 80%, which can save a lot of feed costs, increase the efficiency of breeding, and through the timely elimination of weak chickens, but also can reduce the risk of chicken infection.The whole growth cycle of laying hens is long, and it needs to go through incubation period, incubation period and laying period. In the incubation period, comfortable temperature, humidity, light and feeding density should be provided according to the physiological characteristics of chicks, so as to ensure better robust growth of chicks.During the growing period, the weight of laying hens should reach the standard, and the feeding quantity should be adjusted according to the weight of laying hens.In period of egg production, take reasonable light stimulation, prompting laying hens timely open and into the egg production peak, reasonable need to adjust the feeding amount, improve the ability of environmental regulation, maintain good environmental conditions, maintained at a higher egg layers are level, with declining rate of chickens, reduce feeding amount at any time, to avoid excess fat chickens deposition and affect rate.In the whole breeding cycle of laying hens, only scientific methods, fine feeding and management measures can ensure the good growth and development of laying hens, and then produce the maximum economic benefit.Want to know more exciting content, come to pay attention to shengqun breeding lecture hall
