Tips for raising 817 broilers

Choose chicken seedlings: do not select diseased chickens with omphalitis and white dysentery symptoms. Feeding method: the flat feeding method of scaffolding plastic net is adopted. Temperature and light: the temperature of 1-day-old should be stable at 36 ℃-37 ℃. Ventilation: proper ventilation. Master the humidity in the chicken coop: the humidity is kept at 65% and 70%. Pay attention to picking chicks and raising in groups: the small chicks are raised in isolation. Material restriction and water control: water should be controlled for 0.5-2 hours before medication.

First, choose chicken seedlings

1. Select the chicken seedlings from the breeding places with high reputation. When picking up the chicken seedlings, you should pay attention to eliminating the diseased chickens with symptoms of omphalitis and white dysentery, and then eliminate the weak and residual chickens, and do not buy low-quality chicken seedlings.

2. High temperature brooding can effectively reduce the harm of salmonella, maintain a high temperature of 37 ℃ during culture, and use sensitive antibiotics to control the spread of bacteria, such as neomycin, florfenicol, amikacin and so on.

2. Feeding methods

It is suitable for broilers to be raised on the scaffolding plastic net and on the ground, which can easily make the chickens catch cold and cause diarrhea and other symptoms, leading to colibacillosis and coccidiosis.

Third, temperature and light

1. The temperature of 1-day-old should be stable at 36 ℃-37 ℃. Generally, too low temperature is not conducive to yolk absorption.

2. Keep 24 hours of light in the first 2 days of age, with a 40-watt light bulb for every 15 square meters.

3. Keep the light for 23 hours from 3 days old, then stay dark for 1 hour, and turn off the lights at 12:00 at night.

IV. Ventilation

1. In the early stage, we should not only pay attention to heat preservation while ignoring ventilation, and in the later stage, we should not ignore heat preservation, especially in the seasons of chicken disease, climate change and large temperature difference between day and night, and there can be no cross-hall wind. In the cold winter, the air in the chicken house is poor, prone to chronic respiratory disease, colibacillosis, ascites and other environmental diseases.

2. Generally, it can be ventilated properly at sunny and warm noon, disinfected with peracetic acid in the chicken house, neutralize ammonia, and add some microecological agents in the feed, which is helpful to reduce the ammonia odor produced by feces.

5. Master the humidity in the chicken coop

1. Chicks are prone to respiratory diseases and colibacillosis. If the relative humidity in the front house is low and the humidity is too low, measures such as air spray, ground water spraying, and adding water basins on the stove can be adopted to keep the humidity at 65%, 70%.

2, do not appear the phenomenon of high temperature and low humidity, in order to prevent chicken dehydration, but also pay attention to ventilation.

Pay attention to picking chicks and raising in groups

1. The first selection of chicks needs to be carried out when the chicks arrive in the nursery, and then pick out the weak chicks and chicks to be isolated and fed separately.

2. The second selection of chicks is carried out at the age of 6-8 days, or when the chicks are immunized for the first time, and then the chicks with poor growth and small size are fed separately.

3. The male and female sex of broilers are different, and the physiological basis is also different, so the requirements and responses to nutrition, environment and conditions are also different.

VII. Material restriction and water control

1. In order to avoid excessive growth of broilers, before the age of 20 days, the feed can be properly controlled to prevent nutritional and metabolic diseases such as ascites syndrome and sudden death, and 1% 2% garlic can be added to the feed later, which can not only prevent enteritis, but also promote feeding, and appropriately advance the age of the column.

2. If the chickens are not actively feeding, they can be fed properly. During the onset of the disease, when treating systemic septic diseases such as viral diseases, colibacillosis and coccidiosis, the water can be controlled for 0.5-2 hours before medication. In addition, when the chickens are immunized with drinking water, the water can also be controlled for 2-4 hours.

VIII. Refueling

Broilers need to change feed slowly. If you want to change feed B, you can use the following methods: feed An of 2 + 3 + feed B of 1 + 3 for 1-2 days; feed An of 1 + 2 + B of 1 + 2 for 1-2 days; An of 1 + 2 + B of 2 + 2 for 1-2 days, and then feed all of them.

9. Attach importance to the feeding and management of the breeding period

The main results are as follows: 1. During the period, the de-heating time should be determined according to the season and the health status of the flock. The temperature should be removed after 35 days in winter and spring, and about 20 days in summer and autumn.

2. When broilers enter the breeding period, it is necessary to remove feces and bedding materials in time, and do a good job of sanitary disinfection to avoid the existence and reproduction of a large number of bacteria and viruses.
