Seven Measures to Improve Survival Rate of Broiler Brooders

First, reduce the death caused by feathers Feathers occur in 3 to 5 weeks of age, with the increase of age, the density increased accordingly, coupled with poor ventilation, ammonia and other factors, causing the chicks to defecate. Strengthening ventilation and reducing density are the main measures to prevent feathering. General feeding density includes two aspects: First, each chicken occupies the position of a feeding trough. The second is the number of chickens per square meter. The former affects the intake of food and the latter affects the air quality. The rearing density differs depending on the feeding mode. The ground level is raised and the density should be smaller. On the Internet, the density can be appropriately larger.

Second, timely drinking water, timely hatching hatching hatchlings, generally from the first chicken shell to hatch all 48 hours, together with the injection of Marek vaccine, loading and transport, some chicks hatch time has exceeded 72 hours. At this time, the chickens are in a state of severe dehydration. Therefore, a sufficient drinking fountain with cool water should be prepared before entering the chicks, and the chicks should be trained to drink water in time. Rest after eating 4 to 5 hours, combined with 24 hours of light within 2 days of age, so that the chicks as soon as possible to restore strength and ensure nutrient intake.

Third, strict disinfection, to prevent the occurrence of omphalitis omphalitis, also known as yolk bursitis, is the most common cause of early death of young chicks. Because the chicken's omphalitis is mostly caused during hatching, disinfection of hatchery and eggs is particularly important. The sterilization of eggs is mostly done by formaldehyde and potassium permanganate fumigation. The sterilization of incubators is usually done by thorough cleaning, spray disinfection and formaldehyde and potassium permanganate fumigation.

Fourth, the control of chicken rickets Chicken disease is mainly due to vertical infection in hatchery breeders, mostly occurred within 7 days of age, so within 7 days of drug prevention is very important. General use of gentamicin, kanamycin, ofloxacin, enrofloxacin and other drugs to drink or mix.

Fifth, control the brooding temperature Before entering the chicks, the temperature of the brooding chamber should reach 33~35°C from the ground at a height of 1 meter, and it should be 31~32°C after 3 days, and then decrease at a rate of 2~3°C per week until the natural temperature.

Sixth, feed the full price feed during the broodstock single feed, can cause vitamin deficiency. Mainly vitamin A, vitamin B2, vitamin E, vitamin K deficiency, so must be prepared according to the nutritional standards of chicks nutritionally balanced full-priced feed.

VII. Strengthening management of chicks after 7 days of age Maternal antibodies are higher in 7-day-old chickens. Generally, no virulent infectious diseases will occur. After 7 days of age, they are often mismanaged and cause infectious diseases in chicks.
