The brooding period is the basic stage in the production of chickens. The quality of the brooding work directly affects the normal development of the whole growing period of the chickens. Chicks have higher requirements for energy and protein levels in feed, and require stricter environmental conditions. Therefore, broiler personnel must have strong sense of responsibility.
Prepare for work
First clean the chicken house and rinse it with clean water. Then use a 2% caustic soda solution to wet the ground below 1 meter and soak it. After 24 hours, rinse it with clean water and leave it empty for 7 days.
One week before the seedlings, the heat preservation room was sealed and used formaldehyde, and was sterilized with 100 ml of formaldehyde per cubic meter for 24 hours. Three days before the seedlings were planted, ventilation was allowed to remove the residual gas in the house.
Prepare all items for brooding. Such as insulation thermometers, cleaned dishes (6/1000 - 8/1000), drums, buckets (10/1000 - 15/1000 chicks), feeding Adding water tools, a series of supplies such as honeycomb briquettes and bedding for heat preservation.
Overhaul circuit power supply performance in brooding houses. With cotton cloth, felt or film paper, the space inside the brooding room is rebuilt and the heat preservation effect of brooding is improved. Debug the insulation effect of heat insulation equipment such as flue (coal stove, brooding umbrella, fire broiler and other brooding implements), and raise the temperature to the required temperature for brooding on the day before seedling entry. When the temperature is low, warm up 1-2 days in advance. .
Do a good job of picking up
Contact the transportation vehicle in advance and the vehicle must be completely disinfected. To achieve "prevention from rain, cold, boredom, pressure, and shock."
Put the chicken: After the chick is pulled back, remove it as soon as possible. Put the chicken gently and place it on a litter to rest it.
Start eating and drinking: The chicks are put down for 1 hour, and then they can drink (the first time they are fed with water), and can use 5% glucose or brown sugar to add some multidimensional food. Drinking water for the first time should not be too long to prevent excessive drinking water causing diarrhea. Usually about 30 minutes after the start of drinking, use chicks to feed with the full-price compound feed. Place it on a plate or newspaper and place it so that the flock can feed to feed.
Because the chicken's intestine is very short and very fine, poor digestion, the first feeding should not be fed too full (80% full), so as to avoid the chicks produce anorexia, indigestion. To “eat less meals,†add 6 times a day and night in the previous week.
Brooding environment control
Temperature: The right temperature will directly affect the survival rate of the chicks. In general, the temperature in the first week of brooding is 33°C-36°C, and then decreases by 2°C every week. The temperature of the brooding varies according to the breed.
In general, you can “see chicken Schwennâ€: if the chickens are naturally distributed near the fire source, the spirit is good, and the diet and drinking water are normal, the temperature is appropriate; if the chickens are far away from the fire source, the desire for drinking is greatly increased, the appetite is reduced, and the spirit is excited. Screaming indicates that the temperature is high; if chickens gather around the fire source and do not want to move around, the feathers are fluffy, and the “squeaky†sounds indicate that the temperature is low.
Humidity: The humidity in the first week is 70%-80%, and the humidity gradually decreases by about 10% every week. Humidity should not be too high, so that the litter is too wet and prone to coccidiosis; humidity is too small and it can lead to litter too dry, too much dust inside the respiratory disease. If the humidity is too high, increase the temperature and ventilate it.
Ventilation: poor ventilation, excessive ammonia gas and carbon dioxide concentration in the house can easily lead to respiratory disease in chicks and lack of oxygen in chicks, resulting in ascites. Therefore, the fresh air in the house is the key to the survival rate of the chicks. The ventilation of chicks should be based on the principle of "from top to bottom, from inside to outside, flexible ventilation."
The so-called "from top to bottom", that is, ventilation from the opening of the ceiling, to prevent the wind from blowing the chicken body caused by stress. "From the inside out," that is, from the "environmental housing" in a small environment, the first cycle of ventilation, with the increase of age, and then gradually expand the scope and intensity of ventilation.
Note: Do not let the wind blow the chicken body during ventilation; adjust the relationship between ventilation and heat preservation. Ventilation must first raise the temperature, avoid ventilation, the temperature drop caused by the temperature difference is too large, causing adverse effects on the flock.
Illumination: The chick's vision development is very poor, coupled with its just hatched is not sensitive to new things outside the world, in order to stimulate its nervous system development we can generally use strong light stimulation, that is, the first 3 days 24 hours, more than 60W incandescent lighting , 4 days - 7 days can reduce the light intensity, with 40W incandescent lighting, lamp height 1.5 meters - 2 meters, light from 2 meters - 2.5 meters.
Density: The density directly affects the survival rate and evenness of the chick. Its size is related to the breed and size of the chicken. In general, the chick density should be 50-80/m2 in the previous week, and the density should be adjusted in time according to the growth rate of the flock.
Grouping, splitting: Chickens must be sized, divided into groups after 3 days to reduce unnecessary deaths. The weak seedlings should be singled out at the place where the temperature is most suitable, and the glucose water and the syrup with higher concentration should be fed separately. If it is not possible to drink water, it should be dripped as much as possible to eliminate the defective seedlings in time and reduce feed wastage. The group size of one-week-old chicks is 500-800, and 1000 chickens can be used as a column.
Litter Hygiene: After the chicks enter the bar, they should apply a large amount of litter, such as cereal straw, to prevent the chaff and sawdust from entering the chick's eyes too much. The grass should be cut into 5 to 8 centimeters long, spread 1 to 3 centimeters thick.
The excrement of the early chicks contains a large amount of pathogenic microorganisms, so the excrement is generally removed in about 3 to 5 days. Can be replaced with chaff, sawdust, etc. as a litter, 10 to 12 days for the second time excrement. However, if the litter is too wet, it should be cleaned in time to ensure that the litter is clean and hygienic.
Strengthen drug prevention
Prevention of white lice: In general, chicks must fight antibiotics such as Ceftiofur, Gentamicin, Amikacin, etc. before hatching. From 1 to 7 days after entering the seedlings, drugs for the control of white peony and E. coli must also be administered, mostly based on white peony. Can use doxycycline (0.04% spices), neomycin (2000U/ only - 3000U/, drinking water), amikacin (1000U/ only - 2000U/, drinking water).
Vitamin supplements: Chickens should be supplemented with electrolytes, water-soluble vitamins, especially B vitamins and VE supplements to prevent chicks from developing soft foot ailments.
Vaccine immunization: Establish a reasonable immunization schedule based on the prevalence of local epidemics. At the same time, the chick's body is very fragile, so when it comes to making vaccines, it is important to take good care of the methods of handling, and take care to minimize the stress so as not to hurt or kill the chicks and affect the survival rate.
