More and more chicken farmers choose to raise broilers in broiler cages for sale. It is important to know that there are a large number of harmful microorganisms in the natural environment of broiler chickens. The waste, eggshell, and fluff of the hatchery, plus the temperature and humidity conditions during hatching, are also a good environment for breeding and growth. If you do not pay attention to the strict disinfection of the hatchery environment, hatching equipment and eggs, once the epidemic is prevalent Will have disastrous consequences.

Broiler farmers recommend that the hatchery environment and poultry farming cage equipment should be disinfected once a week. The concentrations used were 1%, 0.3%-0.5%, 5%. The disinfectant is sprayed with water at the concentration used above. The hatchery should be kept clean. It is strictly forbidden for the incubator to be a non-worker. The staff entering the hatchery should also be strictly disinfected and changed to enter. The disinfection of the incubator is mostly based on formaldehyde fumigation. Generally, 42 ml of formaldehyde solution per square meter of space is added with 21 g of potassium permanganate, and the temperature is 20 to 2490, and the relative humidity is 70% to 80%, and the fumigation is closed for about 30 minutes. The disinfection of the eggs is as early as possible after the chicken body is produced, but the production is often carried out after centralized collection of eggs. There are many methods for disinfection and disinfectants used, but it is commonly used to fumigate with formaldehyde. The dosage is 28 ml of formaldehyde per cubic meter of space, 14 g of potassium permanganate, and fumigated for 20 to 30 minutes. Special attention should be paid to: hatching 24-% of the eggs, the embryos are very sensitive to formaldehyde, do not use formaldehyde fumigation at this time, if necessary disinfection, can be replaced with other disinfectants.

Incubators and eggs should be disinfected after hatching and placing. The method and the amount of formaldehyde are basically the same as the disinfection of the eggs. It should be noted that the time to use formaldehyde fumigation after the tray is shorter, usually 10-15 minutes. Formaldehyde gas is strongly irritating to the mucous membrane of animals, and should be used for its own protection. The formaldehyde gas in the incubator and the egg store should be quickly eliminated after each disinfection. Some hatcheries have tried formaldehyde fumigation of freshly shelled chicks to control Marek's disease and chicken white mites. The production practice proves that the method of raising chickens in chicken equipment is difficult to control due to formaldehyde concentration and fumigation environment conditions. If it is slightly careless, it will lead to blindness of the chicks, so it should not be promoted.

When farmers use broiler rearing equipment for cultivation, the initial investment is large, especially for large-scale farmers, which require more automation equipment, but these equipments are necessary and can be used for a very long period of time. In addition, the feed is a big expense. Then, when raising chickens, how should farmers reduce the cost of breeding while ensuring the health of the chickens?

1. Adjustment of feed formula: in actual production, high-yielding chickens' egg production peak can last for more than 4 months, and the maintenance time of high-level feed nutrition should be appropriately extended. After that, the amount of high protein feed should be reduced according to the decrease of egg production rate to avoid nutrient waste. The vitamin content and protein level in the feed can be increased appropriately when the chickens are immunized, sorted, transferred and debeaked. Feed little and feed often. Do not feed more than 1/3 of the feeding trough each time, try to let the chicken feed trough to eat the feed before adding, strictly prevent the rest of the feed moldy deterioration.

2. Avoid waste: feed should be less to the diligent, each feeding does not exceed 1/3 of the feeding trough, try to let the chicken feed the feed in the trough and then feed, to prevent the remaining feed from mold and deterioration. At the same time, pay attention to the storage of feed and raw materials, and avoid rats.

3. Timely and correct debeaking: the experiment shows that debeaking saves about 6% of the feed compared with the chickens with continuous debeaking, and the experienced workers can be arranged to debeaking the layers when they are 7-9 days old.

4. Eliminate bad individuals: pay attention to observe the chickens, and find that sick chickens, weak chickens, low-yield chickens, and stopped chickens should be eliminated in time. These chickens generally account for 3%-5% of the total number of flocks. For each additional day, each chicken needs to consume 100 grams of feed. Some chicken farmers often cannot decide to eliminate them, and the result is a waste of feed.

Breeders must have certain chicken raising experience in order to accurately eliminate "useless chickens": hens with crowns, pale faces, crowns shrinking, and yellow legs should be eliminated. The distance between the phalanges of the normal laying hens is more than 3 fingers, and the distance between the phalanges and the sternum is more than 3 fingers. When the peak of laying eggs is over, it is found that the distance of the chicken's phalanges is less than 1.5 fingers, and the crossbow is less than 2 fingers, too fat or too thin. Hens should be eliminated in time; abdominal enlargement, accumulation of water in the abdominal cavity or accumulation of more liquid, hens with inconvenient walking should also be eliminated in time.

The above is a summary of the methods used to reduce the cost of breeding in the process of using broiler battery cages for aquaculture.
