Management and precautions after picking up a chick
The characteristics of chicks 1. Chicks are more suitable for transporting animals, because the chicks are still in post-developmental state within two days of hatching. In actual production, we often find that chicks placed in hatcheries for 24 hours appear to be better mentally than chicks who have just hatched. 2. The chick's umbilicus is exposed to external wounds within 72 hours, healing itself after 72 hours and falling off. 3. The yolk sac of the chick weighs about 5-7 grams and contains various nutrients needed for the life of the chick. The chicken can survive for 5-7 days. The sooner the chicks start drinking and eat, the faster the yolk absorption. Research shows that the offspring of young hens are better reassured in terms of brooding temperature, especially humidity, than offspring of adult or older hens. Temperature (first three days) 31~33°C, humidity 50%~60%. Pick-up procedure 1. Regardless of seasons, it is necessary to preheat the chicken house 1 to 2 days before the hatching. When the chicks are broiled, the temperature of the chicken house can be 28 to 30°C. After releasing the chicken, slowly raise it to the required temperature. 2. After the chicks are transported to the chicken farm, they should be unloaded quickly. After the chicken box is placed in the hen house, it cannot be placed in a pile. It should be leveled on the ground. At the same time, remove the chick lid and remove the chicks from the box within half an hour. 3. Some customers should check the quality and quantity after receiving the chicks. It is better to remove the car from the chick box to be checked and spread it out, and then assign someone to check it. Can not be spot checks in the car or check in the chicken house, which often results in heat stress rather than gain. The critical heat stress temperature for chicks is 35°C. Studies have shown that in the summer when the hatchery is stopped for one minute, the temperature in the chick box rises by 0.5°C. Feeding antibiotics early in brooding can improve survival and evenness After receiving the chicks, do not add any drugs in the first pass of drinking water. Change the water and start adding antibiotics. The drug selection is as follows: 1.2 to 6 days old, 9 to 12 days old, gentamycin, kanamycin, amoxicillin, florfenicol, etc. 8 to 12 mg/day, given twice, each time limited to drink 2~ 4 hours. Studies have shown that one-time feeding has doubled toxicity and reduced efficacy by half. 2.16 to 20 days of age, gentamicin, amoxicillin, tylosin, etc. each 12 ~ 15 mg / day, divided twice. Do not consider the problem of bacterial resistance because our breeders do not feed such drugs during the laying period. Note: Tylosin cannot be combined with polyether antibiotics, otherwise it will increase the toxicity of the latter. Such as: Monensin, salinomycin, Maduramycin and other anticoccidial drugs. Do a good job of vaccination and disinfection 1. Ventilate on the first day of the chicken. Due to the high temperature and humidity of the brooding house, it is easy for bacteria to multiply. Therefore, the bacteria content in the brooding house is the highest. The minimum ventilation standard is 0.5 to 0.7 cubic meters per kilogram of body weight per hour. The ventilation volume per 10,000 cubic meters requires an intake area of ​​0.15 square meters. Example: 10,000 chickens, weight 45 grams, total weight 450 kg, 315 cubic meters of air per hour, ventilation volume of 20,000 cubic meters of ventilation per minute of 330 cubic meters, the first day of ventilation 1 In minutes, after adding 100 kg of body weight every day, it is necessary to increase the flux by 20% every day. 2. It is very important to start chicken sterilization work from the very next day. The chicken sterilization work can be avoided on the day of immunization and will not affect the immune effect. During the brooding period, the chicken should be shut off when it is sterilized. Disinfection runs through the entire feeding process. Late disinfection means no disinfection. 3. At the request of the client, our company spray-immunized the ND+IB live vaccine at the age of 1 day, and the client can be repeatedly immunized at 7-10 days old. In multi-day-old chicken farms, new seedlings should be inoculated at 5 to 7 days of age. Pick chickens and groups early to prevent the emergence of oversized chickens In the first two weeks of brooding, chickens should be picked at any time, and young chicks who have just entered 1-2 days should be allowed to drink and eat as soon as possible. Weak and small chicks need to help others to eat and drink, and we must eliminate them timely in order to eradicate them. Parents also have the task of selecting breeding chickens, and we must take the initiative to eliminate 0.5% to 1% of females in the first two weeks. %~2%, to pick out 5% of weak chicks, to restore their health through feeding, multiple feeding, and reducing the rearing density. At 4 to 8 weeks of age, the weight exceeds the large group average weight of 5%. ~10%, then gradually mix it into large groups.
