What rules should new farmers follow in feeding and managing 49-day-old slaughtered broilers?

The purpose of careful management of broilers is to give full play to their genetic potential and improve their production performance. There are two main indicators to measure the production performance of broilers, one is weight, and the other is feed efficiency, that is, as little feed as possible in exchange for as much weight gain as possible. Therefore, in addition to the comprehensive nutritional feed for broilers, other aspects must also be paid attention to: First, adopting the feeding system of all-in and all-out is the fundamental measure to ensure the health of chickens and cut off the source of infectious diseases, and it is also an important part of broiler production planning management and a successful experience of modern broiler production technology. Second, there are many factors to consider when deciding the slaughter age and the slaughter age of broilers. Third, do a good job in environmental control. The level of broiler production depends first on its own genetic potential, and whether this potential can be fully exerted is closely related to the environment in which broilers live. Therefore, the basic requirement of broiler management is to create a living environment conducive to the healthy and rapid growth of chickens. New farmers can refer to the 49-day slaughter rule:

Before the chicks enter the house, they should make good preparations for receiving chicks, disinfection of chicken coops, heating, cleaning and disinfection of utensils, feed, medicines, vaccines, drinking water, etc. After chickens enter the house, they should be raised and managed according to the rules in order to receive the expected economic benefits.

1 day-old chicks fill the drinking fountain with warm water of about 20℃ 2 hours before entering the park, add 5% glucose, put the chicks into the brooding room according to the requirements of feeding density, and let the chicks rest for 20 ~ 30 minutes. After that, put it in the water dispenser for the chickens to drink. Tap the water dispenser gently to lure the chicken to drink. For slow-reacting chicks, start drinking water manually. Grasp the chickens gently, press their beaks into the water, or feed them with a dropper. Be sure to let all the chickens have their first sip of water. Eat 2 ~ 3 hours after drinking water. The starting material can be a complete granular material for broilers, or millet or corn grits. Carefully observe the feeding situation and let the chicken eat 80% full. The survival rate of weak chicks can be improved by feeding them in rows or boiling porridge with milk powder and egg yolk in equal parts and feeding them drop by drop with a syringe. Adopt 24-hour illumination, 2.7 watts per square meter, 2 meters above the ground, and feed/kloc-0 every 2 hours, with few feeding times. The temperature of the chicks' activity place is 34℃, and the humidity is measured by a hygrometer. If the breeder's throat is dry, it proves that the humidity is low, and hot water can be sprayed to improve the humidity. Disinfect the chicken once, spray it evenly, and the drug concentration should be prepared according to the instructions. There should be personnel on duty at night to control the fire, prevent the temperature from dropping at night and pay attention to prevent gas poisoning. 2-day-old chicks are fed once every 2 hours, the feeding amount is accurately controlled, the dirt in the tank is cleaned at any time, and the water dispenser is cleaned twice. During 1 week, chicks should be allowed to drink warm water of about 20℃, and the dynamics, food intake, water consumption and fecal color of chicks should be observed. The chicks had better be active and evenly distributed, and don't gather together. Pay attention to temperature, humidity, ventilation and 24-hour illumination. Feed broilers 1. Feeding 10 times a day for 3 days old, picking up the feces and dirt in the tray at any time, and accurately weighing the feeding amount. Clean the water dispenser. Change disinfectant at the door, observe the chickens and make records. The temperature is controlled at about 32℃ and the humidity is 65% ~ 70%. Disinfect chickens once, and use more than two kinds of disinfection drugs alternately to avoid drug resistance. Light for 23 hours, turn off the lights at night 1 hour. Before turning off the lights, take out the water dispenser to prevent chickens from colliding with each other in the dark for the first time and get wet, and illuminate with a flashlight to check whether there is chicken aggregation. Feed every 3 hours when you are 4 days old and clean the water dispenser. Replace disinfectants, prevent gas poisoning, clean up feces, observe chickens, pick out weak chickens and raise them in pens, and deal with dead chickens in time. The indoor temperature is controlled at 32℃, the humidity is 65%, and the indoor light is 23 hours. Pay attention to ventilation. Disinfect 5-day-old chickens and adjust the house temperature to 30 ~ 32℃. Other management measures are basically the same as those of 4-day-old chickens. Six-day-old chickens are fed eight times a day, and the 1/3 tray is removed and replaced with a medium-chicken bucket chassis, with 50 chickens per kloc-0/chassis. Lighting for 23 hours, the intensity is 0.9 W/m2. Clean up the feces, pay attention to ventilation and observe the chickens. Drink multi-dimensional electrolytic water or water-soluble vitamin water at the age of 7 days, appropriately increase water dispensers and increase the number of barrels. Eye drops and nasal drops use Newcastle disease IV vaccine or Newcastle disease clone vaccine. Before operation, test with 1 ml water, record the number of drops of all droppers, and label the droppers. The vaccine should be diluted according to the instructions and the number of droppers, so that each one can meet the immune dose requirement of 1 drop of liquid medicine. At the same time, 2% chicks can be weighed and sampled at multiple points to be representative. Immune weighing is best done at night. Record the weight, calculate the uniformity, and adjust the feed density to 35/m2. Record vaccine manufacturer, batch number, etc. Drinking water at the age of 8 is the same as drinking water at the age of 7. In order to enhance the immune effect, well water or tap water was used from the age of 8 days. All buckets are used, one for every 35 chickens, and the temperature of the henhouse is gradually reduced to 27 ~ 29℃. Observe the chickens, feces, ventilation and light, and record the feeding and drinking water. The 9-day-old bucket is hung on the roof, and the bottom of the bucket is basically flush with the chicken's back, so that the chicken can eat it at will; Remove the drinking fountains of chickens and replace them with chicken drinking fountains, one for every 40 chickens. Disinfect the chicken. Daily management is the same as before. 10-day-old chickens increased food intake and water consumption, excreta increased, and the odor in the house increased. Therefore, from the age of 10, special attention should be paid to defecation, environmental sanitation and ventilation. Listen to the breathing of chickens after turning off the lights at night, and strengthen the feeding management of weak individuals. 1 1 year, strengthen ventilation and handle the relationship between ventilation and heat preservation. It is very important to keep the indoor air fresh. Adjust the bucket height at the age of 12 days, and then adjust it continuously with the growth of chicken age, so that the bottom of the bucket is the same height as the chicken back. 13 years old drinking water was added with vitamins to prepare for immune prevention of infectious bursal disease. Preparation of infectious bursal disease vaccine. 14 years old, drink Subu-14 or Subu-18 until 1 1: 00 in the morning, remove the water dispenser, wash it with clean water and stop water for 2-3 hours (summer and autumn) or 3-4 hours (winter and spring). Then quit the drinking machine, wash it clean, supplement multivitamins, and resume free drinking. Adjust the feeding density to about 30 animals per square meter. Sampling and weighing at night to calculate the uniformity. 15 years old, drink multivitamin water, adjust the chicken flock, create good conditions for weak chickens and promote their rapid growth. The indoor temperature of 9 ~ 15 days old should be gradually reduced to 24 ~ 26℃. /kloc-routine management of 0/6 days old, disinfection with chickens, enhanced ventilation and good hygiene. Routine management of 17 ~ 18 days old. Routine management 19 days old, prepare No.2 material. 20-day-old feed should be mixed with 30% No.2 feed and 70%/kloc-0 feed, and the feed intake should be observed. Other management is the same as before. 2 1 day feed should be mixed with 70% No.2 feed and 30% 1 feed and stirred evenly. 2 1 ~ 42 days old is prone to infectious bursal disease. Observe the feces carefully. If you find milky and thin feces, please ask the veterinarian for treatment immediately. Sampling and weighing at night. Adjust the feeding density to 10 ~ 12 per square meter. Disinfect the chicken once after adjustment. At the age of 22 days, all the No.2 materials were used. From the age of 22 days, the indoor temperature gradually dropped to 265,438+0 ~ 23℃, and the humidity was controlled at 55% ~ 60%. Routine management of 23 ~ 24 days old, observation of chickens, strengthening ventilation and maintaining environmental hygiene. At the age of 25 days, routine management was carried out, and multiple vitamins were added to drinking water to prepare Newcastle disease IV vaccine or Newcastle disease clone vaccine. At the age of 26 days, drink multivitamin water until 165438+ 0: 00 am, remove the water dispenser for cleaning, and stop the water supply at the age of 14 days. Then, give the chickens water, add twice the amount of Newcastle disease IV vaccine or Newcastle disease clone vaccine to the water, and supply 45 ml of water to each chicken. Add 0.3% skimmed milk powder to the water. Let the chickens finish drinking within 2 hours, and make sure that all chickens can drink water with vaccine. After drinking vaccine water, clean the water dispenser and continue to drink multivitamin water. Conduct daily management according to operating procedures. Drink multivitamin water at the age of 27 to enhance the immune effect. Pay attention to ventilation, observe feces, and listen to chickens breathing at night. At the age of 28, strengthen ventilation, and when the temperature is too high in summer, use fans or other measures to cool down; While keeping warm in winter, pay attention to ventilation, and control the indoor ammonia concentration below 20ml/m3. Sampling and weighing at night, and comparing with the recommended weight standard, find out the shortcomings, take remedial measures, and disinfect the chickens once after weighing. Daily management of 29 ~ 30 days old, pay attention to ventilation, observe chickens and pay attention to ascites sick chickens. 3 1 day-old drink multivitamin water to prepare infectious bursal disease vaccine (if the local chicken population density is low, infectious bursal disease is not prevalent and secondary immunization is not needed, then 3 1 day-old only carries out routine management). 32-year-old, drinking multivitamin water until 1 1: 00 in the morning, taking down the water dispenser, washing it, stopping water supply for 2-3 hours, adding infectious bursal disease vaccine into 50 ml of water, and drinking it within 2 hours, then cleaning the water dispenser and continuing to drink vitamin water. Pay attention to the breeding density and indoor air, and wipe the light bulbs frequently. Drink multivitamin water at the age of 33, carry out routine management and pay attention to ventilation. Daily management of 34-35 days old, preparation of No.3 feed; At the age of 35 days, the fuel should be replaced. Add 1/3 to No.3 material, and add 2/3 to No.2 material, and mix well. Sampling and weighing at night, and disinfecting the chicken once after weighing. Add 2/3 to 36-day-old No.3 material and 1/3 to No.2 material, mix well and pay attention to ventilation. At the age of 37 days, all the chickens were fed with No.3 feed, and the chickens were properly driven away to reduce the lying time, so as to reduce the occurrence of chest cyst disease, increase the feeding times and stimulate the broilers to eat. 38 ~ 4 1 day, strengthen ventilation, and control the room temperature at 20 ~ 22℃ to stimulate appetite. It is best to have a half-hour period every day to increase the feed intake of broilers. Daily management of 42 days old, weighing at night (if you have reached the slaughter weight, you can prepare to slaughter). Then take the chicken to disinfect it once. At the age of 43 ~ 44 days, remove the drugs from the feed and prohibit the use of any drugs in the future. At the age of 45 days, the chickens were disinfected for the last time. Strengthen management at the age of 46 ~ 48 days, pay attention to temperature, humidity, feeding density, ventilation and light, and clean up feces in time to ensure the stability of indoor environment. Blow take the chicken gently several times a day to stimulate feeding. Determine the slaughter time according to the weight and feed surplus, and contact relevant departments to prepare for slaughter. 49-year-old, withdrew the bucket 12 hours before slaughter, and took away the water dispenser 3 hours before slaughter. When putting out the stall, the posture of catching the chicken should be correct, so as not to cause losses such as fractures and bumps. Record the number of chickens, and carry the chicken raising contract, notice of quasi-slaughter and quarantine certificate, and feeding medication records to the slaughterhouse with the vehicle.

Finally, summarize and calculate the input and output. The henhouse was thoroughly cleaned and disinfected, and left empty for 7 ~ 10 days to start the next cycle of production.
