What are the management of breeder brooding
The brooding stage is the beginning of the growth period of the breeder. It requires us to feed it more carefully according to the physiological characteristics of the chicken. The quality of the brooding directly affects the evenness of the breeding period and the peak of egg production.
First, prepare before picking
1. Prepare the chicken house:
Thoroughly remove chicken dung from the house and clean the ceiling, walls and ground of the house with clean water. The equipment can be dismantled for cleaning or scrubbing. It cannot be removed and cleaned or scrubbed in the house. The broiler house should then be rinsed with a disinfectant (if the equipment allows it), but after washing with caustic soda, it must be rinsed with water, because the remaining flaming alkali can cause damage to the skin of the chicken. Finally use formalin solution spray or three times the amount of potassium permanganate and formalin fumigation (house temperature should be maintained above 20 °C, humidity 60% or better), fumigation completed chicken house at least closed 24 hours, the first three days before the start of the flue to exhaust, you can warm up while exhausting, so that the formalin vapor can be more completely volatile, to avoid damage to the chicken's respiratory mucosa. When the temperature rises, keep the floor dry so that the floor temperature rises quickly. If it is a ground brooding, do not spread the litter before the broiler house is fully preheated. Wait until the ground temperature rises and then spread the litter completely. Brooding requires that the surface temperature be above 27°C, preferably 28°C to 30°C. Before the chicks enter the house, the temperature of the house should reach an equilibrium temperature of 32 to 35°C.
2. Preparation of personnel and utensils:
With dedicated brooding staff, closed management during brooding, avoid contact with laying sheds and outside personnel, the items are placed in the shed before disinfection. Calculate the number of chickens per pen or cage in advance based on the number of introduced chickens. According to the number of chickens, prepare the number of trays and siphons (30 chickens per tray, 5 centimeters per chicken, 1.5 centimeters per bird per galley, 10 to 15 chickens per nipple drinker, bell Drinking fountains by 80 to 100 chickens/a). Prepare feeds and medicines for chicks; calculate calculators for feed, drug usage, and body weight uniformity; record records of pens, number of dead birds, feed intake, medication, lighting, etc.; weight of chickens Weighing materials such as scales.
Second, pick up
After the chicken carrier arrives on site, let the chicks enter the chicken house as soon as possible. The cold stress has a greater impact on the chicken and avoids staying in the low temperature environment for a long time. After the unloading, the chicken box should not be stacked more than four layers in the shed to prevent overheating or lack of oxygen in some chicken boxes. Two boxes of chickens were weighed at will and weighed. The average body weight at one day was calculated and recorded. Before putting the chicken into the chicken cage or chicken pen, fill the water dispenser with water, add 3% brown sugar or glucose (the water can be divided into multi-dimensional or antibiotics later), and put the chicks in their calculated quantities. Chicken cages or chicken pens are all fed at the rate of 1-2 grams per bird (after each additional feeding amount is increased according to the increase in feed intake of the chicks, and as little feeding as possible), each chicken is mastered. Daily intake (grams per feed? number of feeds per day). Weak chicks should be placed at a higher temperature and can be used to assist in drinking water.
Third, brooding temperature
Temperature is a very important factor in the brooding stage. The temperature of the brooding house should be between 32°C and 35°C, and it should be reduced by 2-3°C per week until 20-22°C. Low temperatures can cause diarrhea in chicks, poor absorption of yolk, and reduced feed intake, making chicks less resistant and susceptible to bacterial or viral disease, resulting in poor growth and development. Excessive temperatures can cause adverse effects such as decreased feed intake, increased drinking water, and thin stools.
If the temperature of the house is low after the arrival of the chicks, the chicks can be allowed to stay in the chicken box for a period of time. After the chicken house temperature reaches the requirements, the chicks are put into the house again. The thermometer in the house should be kept at the same level as the chicks in order to understand the temperature of the chick's location. There will be differences in the temperature of the upper, middle and lower layers of the brooding brood. Try to place the weak chicks on the upper layer or near the heat source and at a slightly higher temperature. The strong, individual larger chicks are placed on the lower layer. According to the chick's performance, it is judged whether the temperature of the chicken house is appropriate. When the temperature is low, the chicks get together, shrink their necks, and are reluctant to move; when the temperature is high, the chicks spread out, breathe open, and hang down their wings. Can also be used to measure chick body temperature to determine whether the chicken house temperature is appropriate, the mercury thermometer thermometer head inserted into the cloaca of the chick, 5 minutes after the thermometer temperature should be 40 °C, if lower than this temperature, should raise the temperature of the chicken house; If it is higher than this temperature, the temperature of the house should be slightly lowered. If the body temperature of chicks in different parts of the house is not balanced, check whether there is a thief in the house and try to keep the temperature in the house balanced.
Fourth, feeding
For ease of management, chicks are best kept in small groups. Each cage is naturally divided into small groups. The flat raising can be divided into several small columns. According to the space of each column, the number of chickens is determined, and the amount of each feeding is calculated according to the number of chicks. Try to make the same temperature in each bar, and feed each chicken the same amount of feed so that the chick has a good weight uniformity from the beginning. Broodstock feed requires full nutrition, balance, and appropriate particle size. The free-feeding phase ensures that there is material in the tray or chute. Each time the material is added, the remaining waste should be promptly removed, and the principle of adding less material should be added. If you plan to do coccidia immunization, the feed must not contain anticoccidial drugs, because the anticoccidial drugs will kill the coccidia oocysts in the coccidiosis vaccine, leading to immune failure.
V. Drinking water
Ensure that the chicks have enough water levels. It is best to let the chicks drink cold, boiled water the previous week. The temperature should be close to room temperature. In the early brooding period, drinking water is often supplemented with nutrients such as glucose and multidimensional nutrients. The temperature of the brooding house is relatively high, which can easily cause bacteria to multiply in the drinking fountain. Therefore, the drinking fountain should be washed daily. Two days before and after drinking water immunization, drinking water must not contain disinfectant drugs. Disinfected drinking fountains, the residual disinfection of the above must be clean, so as not to cause immune failure or affect the immune effect.
Sixth, light
A few days before brooding, light is given 24 hours a day, and the light intensity is greater so that the chicks can find the water level and material level as soon as possible. If the chicks are strong, eating and drinking water are normal, and the body weight can meet the requirements of the varieties, the lighting time can be gradually shortened to 8 hours. The intensity should be suitable for finding water and feed. The darker the better.
Seven, bedding
Ground brooders generally use litter, litter requires soft, good water absorption. To avoid the excessive humidity in the litter, pathogenic microorganisms will multiply and affect the health of the chicks. If you do immunization with coccidiosis, you must have litter within 3 to 4 weeks after immunization, and to maintain proper moisture, in order to ensure the immune effect.
VIII.
Chicks are generally selected to be cut off at the age of 5 to 8 days, and the exact break time is determined based on the chick's health status and immunization time. Vitamin K is added to the feed before it is broken to help stop the bleeding. The hen should be cut off by 1/2 of the upper jaw and the cock should be cut off by 1/3 of the upper jaw. The unskilled person should not be heavy. Regardless of how many people break, try to ensure the same level of disconnection, to avoid differences in the amount of feed due to the difference in the degree of cutting, affect the uniformity of the flock. After the break is complete, check for bleeding. If there is any bleeding, stop the bleeding again. After breaking the chicks, the feed in the trays stays slightly thicker and reduces stress.
Only when we are careful and meticulous at every stage can we make a good start for breeding chickens, so that we can have a high survival rate, good uniformity, and ultimately create higher economic benefits for us.
