Techniques of different stages of Hailan brown-shell hens
1, Hailan brown shell laying hens brooding period: high temperature brooding.
Hailan brown shell hens should be suitable for density, reasonable ventilation and high quality feed. Hailan brown-shell hens against Newcastle disease, bursal disease, transmission and vitamin amino acid deficiency can cause poor growth. The feed and medicine of Hailan brown-shell hens should not be stored in a high temperature brooding room to avoid mildew and quality. Hailan brown-shell hens are fed with water to avoid unevenness. The minimum effect of the breakage stress of Hailan brown-shell hens at 7-9 days is also good. Strive for a success. Note that Hailan brown-shell hens use antibacterial drugs and vitamins within 5 days of the break. At the same time, the thicker feed layer is maintained to prevent the chicken feed from hitting the trough and bleeding. Disinfecting the ground with 1%-3% of the caustic soda solution every day or every 3 days can effectively kill bacteria and coccidia. Reduce disease and bad odors. The density and feed formulation were adjusted according to the body weight of the Hailan brown shell. Hailan brown-shell hens are reared and reared. Hyland brown-shell hens ensure weight and uniformity. If the weight loss of Hailan brown-shell hens is over, the chicken feed should continue to be used until the body weight reaches the standard.
2, Hailan brown shell laying hens focus on good weight farming technology.
Hailan brown-shell hens must reach the standard before 12 weeks of age. Uniformity is above 80%, avoid using inferior feed, strengthen ventilation and disinfection. Hailan brown shell hens focus on Newcastle disease and rhinitis, slow breathing, and colibacillosis. Hailan brown-shell hens use constant or diminishing lighting procedures to prevent premature aging. The growth of the reproductive system of the chickens after the 80-day-old Hailan brown-shell hens accelerated, and the nutrition should be balanced. The occurrence of respiratory diseases and colibacillosis in Hailan brown-shell hens close to 100 days of age may cause serious damage to laying performance, resulting in no peak in egg production.
3. Hailan brown-shell hens require a stable environment and good nutrition management during the laying period.
Hailan brown-shell hens should adjust their nutrition according to their development from the youthful stage to the early stage of laying. The increase of stone powder and protein feed should have a transition of 2-3 weeks. After 90 days of age, Hailan brown-shelled hens pay attention to whether the development of the sternum is normal to prevent calcium deficiency and appropriate vitamin supplementation. The egg laying rate of Hailan brown-shell hens should be about 96% at the peak, and the egg-feeding rate should be maintained for more than 5 months than the 2.0-2.3: 1.90%. The daily feeding of Hailan brown-shelled hens is kept in a uniform and clean tank to ensure that the chickens are eaten evenly and freshly. Hailan brown-shell hens use shading in summer and mechanical ventilation to cool down.
Spraying cold water mist on Hailan brown-shelled hens can effectively reduce the feeding loss and death caused by heat stress, and the disease at the early stage of egg production may cause serious damage to the egg production function. Hailan brown-shell hens focus on the prevention of newcastle disease, transmission, avian flu, throat and other viral diseases, rhinitis, slow breathing, colibacillosis, necrotic enteritis and other bacterial diseases, white crown disease, chicken mites, mites and other parasitic Insect diseases, fatty liver, gout, phlegm, intractable diarrhea, and decreased egg production for unknown reasons should also be taken seriously.
Appropriate calcium supplementation and vitamin AD3 of Hailan brown-shell hens after 300 days of age improve eggshell quality. Appropriate medication between the early stage of development and the peak can prevent inflammation of the fallopian tubes and ovaries, which is good for promoting egg production and maintaining stability. Hailan brown-shell hens should pay attention to the epidemic dynamics of the epidemic and actively take countermeasures to ensure high yield and stable yield. Hailan brown-shelled hens have shorter sunshine hours in autumn and winter, and many chickens with artificially controlled light in the cold often have troubles in switching between lights in the morning and evening, causing photo-induced stress to cause egg drop. Hailan brown-shell hens should actively supplement the light in the rainy and snowy days. It is recommended to use electronic light control to reduce human error.
The requirements for water consumption and illumination of Hailan brown-shell hens.
The consumption of water in Hailan brown-shell hens is directly dependent on the ambient temperature and feed consumption. Feed consumption is dependent on the ambient temperature. At the optimum temperature of 20-25 degrees for chicken growth, the amount of water consumed is twice the amount consumed. When the ratio is changed under high temperature conditions, the water consumption is increased because the feed consumption is reduced.
Light can affect the survival rate of Hailan brown-shell hens. The egg production will also change with the illumination of Hailan brown-shell hens. The light will also affect the total benefit of egg size. The basic lighting guidelines for Hailan brown-shell hens are:
(1) The production of Hailan brown-shell hens should be irradiated with 20 lux of light for 20-22 hours on the first two days of production, from the second day to the eighth week, with 5 lux. The intensity is 8-10 hours per day, from 8th week to 17th week, and it is kept 8-10 hours per day, or placed in a normal outdoor or dimly lit house.
(2) Provide light stimulation when the weight of Hailan brown-shelled hens reaches 1.47 kg. The initial daily illumination time is not less than 1 hour, and the weekly illumination time is not less than 15-30 minutes until reaching 16 hours. The time should continue until the peak of the egg production, the light intensity should be increased to 10-20 lux.
(3) It is not allowed to reduce the light intensity and shorten the illumination time in adult Hailan brown-shell eggs and chickens.
Requirements for temperature, density, humidity and ventilation of Hailan brown shell hens.
1. Hailan brown-shell hens brooding period: 0–3 days old 33–36°C. Humidity is above 60c/o. Afterwards, it will drop 2–3°C every week. Until 21–25 ° C. The specific operation depends on the season and the performance of the chicken. Watch the chicken warm. A reasonable temperature and humidity of one week is critical to increasing survival. Strictly prevent gas poisoning. High temperature brooding is conducive to the absorption of yolk and the survival of weak chickens. And reduce the incidence of chicken white peony and colibacillosis
2, Hailan brown shell laying hens: about 25 °C is more suitable. Low temperature can cause rhinitis and slow breathing.
3, Hailan brown shell laying hen laying period: 17 ~ 26 ° C is more appropriate. Temperature difference of 5 ° C or more is more stressful for chickens. There is a significant gasping phenomenon above 28 °C. Above 35 °C can cause a large number of heat strokes. Poor ventilation combined with high temperatures pose a serious health hazard to chickens. Pay attention to the weather forecast in the autumn and winter season to prevent respiratory diseases from causing a large drop in temperature caused by thieves and strong winds.
4, Hailan brown shell laying hens to 20 weeks old chicken to be moulted 4 times. There are also seasonal and age moulting. The amount of feathers during the breeding period is large. Pay particular attention to ventilation and disinfection. Otherwise it may cause respiratory illness and E. coli.
5, Hailan brown shell laying density: 1 – 2 weeks old cages less than 60 per square meter. Up to 30 or less, and about 40 in a 3–4 week cage. Raise about 25, and raise 20–30 in a square for 5–6 weeks. Raise 20 or less. After 2 weeks of age, the density of flocks is greatly affected and various diseases are induced. The air is dirty in dense flocks. Drinking water is restricted. The source of the disease can accumulate in large amounts. Easy to produce weak chickens become susceptible chickens. Increase the risk of morbidity. Because [provincial places” may pay a higher price.
