With the high temperature in summer, it's crucial for chicken farmers to take extra precautions to ensure the survival rate of their broilers. Various diseases and bacteria can easily breed in such conditions, which can be extremely harmful to the chickens. Here are ten precautions that every chicken farmer should understand and implement for the safety and well-being of their flock.
1. reduce density
When raising chickens in hot weather conditions, it is crucial to consider their density. If the chickens are crowded together, it can result in heat stress. To prevent this, it is necessary to reduce the number of chickens to a reasonable level. This can be achieved by removing sick, disabled, and weak chickens promptly to avoid any adverse effects on the flock's general health.
2. plenty of drinking water
In summer, the temperature is high, and the broilers need more water. In addition, the water should be clean. Unclean water can easily cause diseases. Therefore, chicken farmers should adjust the water line in time in summer to supply sufficient clean drinking water.
3. Electricity matters
In summer, the fan in the broiler house cannot be stopped, and the water curtain cannot be stopped. If the power is cut off for a while, many chickens may die, so make sure that the circuit is ok. In addition, under high temperatures and high loads, electricity is prone to problems, such as fire, so pay attention to protection.
4. Weather changes
In summer, there are not only high temperatures but also strong winds and heavy rain. Chicken farmers should pay attention to not only the temperature but also the humidity, as well as the possible shock, rain leakage, water accumulation, and so on caused by the strong wind and heavy rain.
5. Feeding period
Chickens need to dissipate a lot of heat when eating feed. Chicken farmers should avoid the period when the chickens dissipate a lot of heat, which happens to be the high-temperature period of the day, such as noon. Therefore, feeding in summer is usually in the morning and evening.
6. Feed mildew
In summer, there is high temperature and high humidity, and a lot of rain, so the feed is prone to mildew. In addition, in order to ensure that the feed will not become moldy after not being eaten for a long time after entering the trough, chicken farmers should ensure that the trough is cleaned once a day.
Appropriate light can speed up the weight gain of broilers, strengthen the blood circulation of chicks, increase appetite, help calcium and phosphorus metabolism, and enhance the immunity of chicks. However, if the lighting program in our broiler house is unreasonable, the lighting is too strong or too weak, and the lighting time is too long or too short, it will have a negative impact on the chickens. First of all, I will talk to you about how to scientifically install artificial lighting equipment for chicken coops. The distance between the lights of each chicken coop should be 1.5 times the distance from the lights to the chickens, and the horizontal distance between the lights and the wall should be 1.5 times the distance between the lights. 2/1; The installation positions of the lights should be staggered and evenly distributed. The number of light bulbs installed in each chicken house can be arranged and installed according to the distance between the lights and the distance between the lights and the wall specified above. After the lighting equipment is installed according to the above requirements, the distribution of lighting equipment in the chicken house is in a reasonable range.
The growth rate of the current white-feathered broiler chickens is relatively fast, which creates a contradiction between the fast-growing muscles and the lagging development of internal organs such as the heart and lungs. Because many farmers have adopted some wrong practices in the early stage of feeding, the growth of broiler chicks in the early stage If the speed is too fast, the contradiction between the muscle growth of broiler chicks and the development of internal organs will be more prominent. The poor development of the internal organs of the chicken will lead to the decline of the body's disease resistance, and the incidence of epidemic diseases is frequent and difficult to treat. In the later stage, there are more diseases and it is difficult to raise the strange phenomenon.
The key to solving this contradiction is to control the feed and light well, control the growth rate of the muscles in the early stage of the chicks, adjust the light intensity, promote the growth and development of internal organs, and enhance the body's disease resistance, high cost, and high death rate; use the characteristics of light control and broiler compensation growth to control feed intake, reduce the feed-to-meat ratio, ultimately reduce breeding risks, and improve economic benefits of broiler growth.
7. Heatstroke prevention and cooling of feed
Pay attention to adding heatstroke prevention and cooling products to the feed. Generally, chicken farmers in the summer need to supplement multi-dimensional to improve the ability of chickens to resist heat stress.
8. Temperature and humidity management
If the temperature is too high, ventilation should be enhanced. If it cannot be lowered, water curtains are needed to cool down. Pay attention to the balance of humidity and temperature while raising chickens. When the humidity is too high, turn off the water curtain in time and increase the effect of the fan.
9. Treatment of excessive temperature
If enhanced ventilation and water curtains are used, the chicken still feels very hot, and the chicken farmer can use the spray to cool the chicken house. Take this method to pay attention to smooth ventilation and ensure that the humidity does not exceed the standard.
10. Day and night management
The above are the precautions for broiler breeding in summer. The climate changes in summer vary greatly. Therefore, in order to improve the survival rate of broilers and reduce the losses of chicken farmers, I hope you will keep these management matters in mind.
In the actual production process, many farmers have never thought about controlling the weight of their chickens at all. They think that it is a good thing for chickens to eat more, and the faster they grow, the better. This shows that my chickens are well-raised. As a result, the body weight of the 14-day-old chick usually reaches more than 450 grams, which often causes the chick to grow too fast in the early stage, and then grow slowly in the later stage, with a high feed-to-meat ratio, a passive situation that is prone to disease and difficult to control.
10 days before entering the chicks, the chicks should eat freely, with small meals.
Pay attention to observe the growth of the chicken after 10 days. There is a standard. Generally, it is advisable to allow the weight of the chicken to reach 300 grams at the age of 14 days.
From the age of 14 days, add 2.5 grams of feed to each chick every other day on the basis of the original feed intake. If it is found that the growth is faster, the amount of feed supplied the previous day will not increase or decrease.
At the age of 21 days, ensure that the body weight is 600 grams. The weight of the 14th and 21st day is very critical. If it is well controlled at this stage, more than half of the breeding will be successful.
From the age of 22 days to the age of 28 days, on the basis of the original feed intake, the feed was increased by 2.5 grams per day.
From the age of 29 days, the cumulative increase in feed is 5 grams per day. What needs to be reminded is that the lanugo hair on the head of the chicken must be shed before the age of 35 days. The shedding of the lanugo hair is a sign of the development of the body's immune organs and other organs, and it is also a sign of the end of broiler brooding. If the lanugo does not fade, do not increase the feed amount accumulatively. Maintain the feed amount for 1-2 days according to the feed amount the day before. will fade. After the lanugo fell off, the feed was continuously increased by 5 grams per day. At the age of 36-42 days, the cumulative increase in feed is 7.5 grams per day.
From the age of 43 days, the cumulative increase of feed is 5 grams per day. As long as the feed is not passed, the cumulative increase is increased every day, and the feed is maintained for a few days. At this time, the daily intake of each chicken is limited to 210-215 grams.
3 days before the sale, increase the light, increase the number of feedings, and feed as much as you want. But it must be noted that the continuous feed cannot exceed three days. If it cannot be sold for more than three days, 1000 chickens will quickly reduce the feed by 40 kg, use kidney swelling antidote to drink water, and cannot feed to maintain this feed until it is sold.
light control program
The first purpose of light control is to combine with food control. Without food control, it is not only difficult to control weight, but also there will be turmoil due to hunger, competition, fighting, feather pecking, etc., which will increase the death rate; the second purpose of light control is Let the chicken be quiet, and the dark light environment is conducive to the development of chicken viscera.
1-7 days of age, light for 22--24 hours, the intensity (the light is 1.8 meters from the ground) 2.5--4 watts/㎡.
8-13 days old, light for 16 hours, and the intensity is about 1 watt/㎡.
14-21 days old, except for the supplementary light until 8 o'clock in the evening in early spring and winter, all other seasons are under natural light, and no supplemental light is provided at night.
22-42 days old, increase the light for 1 hour a day, the longest light time is maintained for 22 hours, and the intensity is about 1 watt/㎡.
After 43 days of age, maintain 22 hours of light with an intensity of 3-4 watts/㎡.
