Brooding technique of Reed Chicken on Plateau

Ecological stocking is seasonal, and the best time for brooding is from April to August every year, and the weather in other months is cold, so it is not suitable for this way of feeding. Generally speaking, it is better to use online brooding in the house. The air quality generally requires that people do not feel the pungent smell after entering the brooding room; make full use of natural light during the day, mainly artificial light at night, and the intensity is generally controlled in the early day and night lighting, and then as the day increases, the light time and intensity should be gradually shortened and weakened; during the brooding period, it is best to feed full price chicken feed, and its crude protein can be controlled at 17% ~ 19%. Eat freely and drink clean water freely every day.

Key points of feeding and management of chicks in the first week

In addition to the survival rate of Luhua chicks is related to the quality of purchased chicks, the feeding management in the first week is the most important factor affecting the survival rate of chicks. In addition, the body weight and evenness of 1-week-old chicks have a significant impact on the following weeks, so it is very important to do a good job of feeding and management of chicks in the first week. The following goals should be achieved one week before brooding: the flock is healthy, the mortality rate is less than 2%, the body weight is 45g, and the evenness is more than 85%. How to achieve the above goals, we need to grasp the key control points of daily management to provide a stable and suitable growth environment for chicks.

1. Eating: it is appropriate for chicks to start eating about 2-3 hours after the first drink, and begin to feed expanded pellets (full price feed for broilers). Each chicken is fed with 1 g feed every 2-3 hours, and the feed is evenly sprinkled on the plate; on the 4th day, the feed bucket is used to facilitate the feeding of chicks; at least 4 times a day.

2. Drinking water: the first drink of a chicken. The earlier the first drink, the better, because the chicks consume a lot of water after coming out of the shell. According to research reports, the body water consumption is 8% after 24 hours and 15% after 48 hours, so early drinking water can promote intestinal peristalsis, absorb residual yolk and defecate, increase appetite and feed absorption, and improve the survival rate of chicks. Add 6% glucose to the water to supplement energy, add water-soluble vitamins to enhance the disease resistance of chicks, and add antibiotics (for example, 0. 5%) to the water on the second day after the first drink. 2% chlorothalonil) can improve the survival rate and promote the growth of chicks. According to the actual conditions, use the drinking fountain in the first 3-7 days, change the water 4-6 times a day, and then gradually transition to the use of automatic drinking pipes to prohibit the phenomenon of water cut-off. The drinking fountain should be cleaned once a day, and the drinking water pipe should be washed and disinfected once a month.

3. Light: the effect of light on the growth of chicks is not direct, but indirectly by means of the effect on the feed intake of chicks, and the light intensity should be more than 20l x. The 60 W ordinary light bulb can be used in the first week, and the lighting time can be reduced by 1 hour every day from the 4th day.

4. Temperature and humidity: the temperature of chicks was generally controlled at 33-35 ℃ in the first 3 days, and increased by about 1 ℃ if the chicken was weak, and 32-34 ℃ in 4-7 days. Keeping the temperature suitable, uniform and stable is very important to the health, growth and development of chicks, and is the key to raising chicks. First of all, make sure that the temperature in the henhouse is uniform and the difference is no more than 1 ℃. Uneven temperature directly results in uneven development and uneven physique of chicks, which increases the difficulty of raising chicks; secondly, keep the chicks stable and keep the temperature down no more than 1 ℃ per day. It is best to work out a detailed daily temperature control plan according to the target temperature at the end of brooding. For example, the target temperature for 42 days is 23 ℃, and the temperature can be reduced by 1 ℃ every 3 days during the brooding period, so as to achieve the goal of smooth de-temperature. When raising chicks, it should also be combined with "watching the chicks and warming them." The humidity should be kept at 40% ~ 60%, the humidity is too low, the chicks are easy to be dehydrated, and the increase of dust in the air is easy to damage the respiratory mucosa of chicks to induce respiratory tract diseases. In the case of high temperature and low humidity, we can increase the humidity and reduce the temperature by means of chicken disinfection, and purify the interior of the house at the same time; in the case of high temperature and high humidity, the adverse effects of high temperature and humidity on chickens can be reduced by increasing ventilation, and for low temperature and high humidity, the ventilation rate can be increased while increasing the temperature in the house.

5. Ventilation: the purpose of ventilation is to ensure adequate oxygen content in the chicken house (19. 6%), remove excessive heat from the chicken body, remove moisture, reduce dust, and reduce the accumulation of harmful gases, such as ammonia and carbon dioxide. Ventilation method: in the early stage of brooding, heat preservation is the main and ventilation is the auxiliary. The purpose of ventilation is for proper ventilation. During the day, the external temperature is high and the activity of the chicks is large, which can appropriately increase the ventilation, while the external temperature at night is low and the activity of the flock is small, so the ventilation should be reduced. The wind speed and ventilation in the first week are not easy to be too large, so it is appropriate for people to feel comfortable and comfortable.

The management of young chicks

First of all, combined with the outdoor climate, the chicks will be driven to the outdoor grass or open slopes at noon on a sunny day for stocking, so that they can freely feed on plant seeds and insects. The stocking time should be flexibly controlled in the light of outdoor climate and chicken activities. Return to grazing and training at the same time of stocking. The specific measures are as follows: in the process of stocking, consciously sprinkle a small amount of medium chicken grains and grain on the grass or sloping land, knock on the feed basin or blow the whistle to form a conditioned reflex, so that after hearing the sound, there is something to eat, which is convenient for future grazing.

Chicken feeding tube

After a period of training, the chickens gradually adapt to the external climate and environment, and after they have formed the habit of grazing and returning to grazing, they should graze all day, and the pasture should choose Arbor woodland (commonly known as bright-footed forest). At the same time, they should choose places where there are no animal pests. Sheds should be built for wild grazing. In order to build a shed, we should choose a place with leeward, sunny, high and dry terrain. The shed can be built with local materials, as long as it can be protected from rain and sunshade during the day and proper heat preservation at night. Grazing woodland should decide whether or not to purse seine according to the grazing level of managers. The purse seine can use a fish net with a mesh of 2cm × 2cm, with a height of 2.5 m. Regular inspection in time during grazing, found that the net broken should be repaired immediately to prevent fleeing chickens. Stocking density: it is suitable to graze 800m and 1,200 animals per 667m2.

According to the specific grazing and feeding conditions of chickens, appropriate supplementary feeding can improve the growth rate and evenness of chickens. In addition, clean drinking water should be placed in many places, and chickens must be harvested every evening during grazing. Combined with the situation of grazing, we can consider whether to supplement feeding, count the number of chickens, observe their health status, and summarize the situation of grazing every day.
