What are the problems with broiler farms? The following slowly explain
1, strictly control the temperature
Temperature control is an important factor in the success or failure of raising chickens. Excessively high or low temperatures can affect the diet, activity, and rest of the chicks, resulting in poor absorption of the yolk, decreased resistance to disease, retarded growth, and even death. Specific measures: look at the chicken Shi Wen, at the most appropriate temperature, always see about 5% of the chicken mouth breathing, chickens distributed evenly in the house. The principle of temperature control is: early high, low late; weak young high, strong young low; small high, large low; rainy days high, sunny low; night high, low during the day. Changes in temperature should be gradually and steadily carried out in accordance with the growth of age and temperature, and must not change at any time. The temperature requirements for different ages at the same height as the broiler chicken are: 1-35 days old 34--35°C; 4--7 days old 32--33°C; 8-14 days old 30--31 °C; 15-21 days old 28--29 °C; 22--28 days old 26--27 °C; 28 days later not less than 24 °C, cold winter, the indoor temperature can be appropriately increased 1- 2 °C.
2, strict humidity off
The relative humidity of the 1-7-day-old chicken house is about 65%. After 7 days, as the chicken's drinking water and excrement volume increase, the water content increases accordingly. The general requirement is about 60%. High temperature and high humidity are easy to smolder because of the low calorie content in chicks, loss of appetite, decreased resistance, and slow growth; high temperatures and low humidity can easily lead to poor absorption of intra-abdominal protein, dry and brittle hair, dry toes, dehydration, and vulnerability to respiratory infections. .
3, strictly control the density
On the Internet at the time of flat raising, 2-4 weeks old 40/m2, 3-4 weeks old 30/m2, 5-6 weeks old 25 birds/m2, 7 weeks old to market 20/m2; three-dimensional cage time 1 - 2 weeks old 60/m2, 3 to 4 weeks old 40/m2, 5-6 weeks old 30/m2, 7 weeks old to market 25/m2. The appropriate relative density will only allow the chicken to eat, drink, and rest, reduce stress and ensure the health of the flock.
4, strict ventilation
It is required to increase the ventilation as much as possible under the premise of ensuring the temperature. Ventilation helps to release toxic and harmful gases in the house. In modern chicken houses, automatic environmental control is generally used. The wind speed is controlled at 0.5m/s to ensure that the ammonia concentration in the house is 10mg/m3, the hydrogen sulfide concentration is 2mg/m3, and the carbon dioxide concentration is within 1500mg/m3. In the winter ventilation, it is generally required to make a choice when the outside temperature is high, and the temperature inside the house is slightly higher than the required temperature of 1 - 2 °C, which can solve the contradiction between ventilation and insulation.
5, strictly control the epidemic prevention
One is to do a good job in disinfecting. Corrosion-resistant walls and floors are sterilized with 2-3% caustic soda or 10% lime water, and disinfectants are used to disinfect chicken rack drinking water facilities (drinkers, drinking water pipes, etc.), and finally all chicken feeding equipment is placed The house was closed and fumigated for 24-48 hours. Specific operations are: 14 grams of potassium permanganate per cubic meter, 28 ml of formaldehyde, divided into multiple settings, dressed in porcelain, the temperature increased to more than 20 degrees, more than 70% humidity fumigation.
The second is to do chicken disinfection. Use 0.2%--0.4% peracetic acid to disinfect the chicken once every 1-3 days, preferably at the noon of the highest daily temperature. Before 10 days of age chickens should be sterilized with warm water and chicken. Dust removal and deodorization, but also adjust the humidity inside.
The third is to prevent disease. 7 days of age: Newcastle disease - Infectious bronchus 2 times the amount of eye; 9 days of age, gac of pox (recommended in May-October each year) 2 times the amount of thorns; 12 days old as early as 8 o'clock in the beginning of the group to stop water, stop water After 2 hours, use infectious bursal vaccine 2 times the amount of drinking water; 16 days of bird flu H5N1 subtype subcutaneous injection of 0.3ml / only; 21 days of infectious bursal vaccine 2 times the amount of drinking water; 28 days old New City Epidemic-contagious bronchi 2 times the amount of water. A total of 3 days before and after epidemic prevention, do not sterilize chickens or disinfect drinking water, and do not use antiviral drugs.
Fourth, do a good job of personnel disinfection. Firstly, farms are strictly prohibited from entering or leaving outsiders. In and out of the area, staff and work inspectors must thoroughly sterilize the footbath, basin, and ultraviolet rays, and wear uniforms in an orderly manner. Do not make loud noises and random squatting.
6, strict drinking water off
After entering the chicken, drink cold water (about 26 degrees) for 3-5 days. The temperature of the chicken is generally about 26 degrees Celsius. After the water temperature reaches Sheshen, the chicken would rather thirsty and drink, and there was a bathing phenomenon. Drinkers should be placed evenly, within the range of chickens 1.5m activity, can not cut off water; often adjust the height of drinking fountains, make the edge of the drinking vessel and the back of the chicken within 7 days of age, the bottom of the drinking fountain above 7 days old is the same height as the back of the chicken. . Drinking fountains must be cleaned and disinfected in a timely manner so that the drinking fountains are cleaned once a day. In order to facilitate the discovery of chicken problems, the amount of water consumed by the birds is recorded daily when conditions permit.
7, strict light off
Light intensity is one of the important factors affecting the growth and development of chickens. Too much light is the main cause of sudden death and ascites in chickens. Too weak light also affects feeding and growth. Generally follow the principle of early strong late light, recommended: 1 - 3 days of age 18W/m2; 4 - 14 days of age 3W/m2; 15 days to slaughter 1W/m2. Illumination is carried out on a 24-hour light at 0-3 days; light is used 23 hours after 4 days; and a closed chicken house is conditioned for 24 hours on a 0-3 day old day, followed by a 1h dark and 2h light batch system.
8, strict feed off
Less additivity is the most important way to increase feed intake. The number of feedings required to be fed 2 times a day after 30 days, 3 times a day for 20-30 days, 4 times a day for 10-20 days, and gradually decreased from 8 times to 4 times a day for 1-10 days. The number of barrels should be sufficient, and the trays should be set at 50--80 pieces/piece. Each time the material is added is 1/3 of the capacity, which means to reduce feed wastage and avoid feed deterioration.
9, strict harmless
Dead chickens and manure can become the root cause of diseases. Rats, dogs, cats, flies, mosquitoes, birds and wild animals can become the media. At present, the simplest method for the disposal of dead chickens is to bury them in depth, such as storing 10,000 broiler farms once, building a round cadaver with a diameter of 1.85m, and sealing and sealing. The treatment method for chicken manure is to build a 100m2 storage manure shed with anti-seepage, anti-leakage, and rain-prevention facilities. The accumulation of fermentation, cool sun, and dry manure collection can be used.
It can be seen that there is no shortcut for broiler breeding. As long as the farm ideologically attaches importance to implementing every detail in accordance with the technical operating specifications, it will create good aquaculture benefits.
