Broiler brooding is a very important part of the broiler breeding process.
The development of various body functions of broilers in the broiler stage is not perfect. And chickens are naturally sensitive. Especially broilers in the brooding stage, are more sensitive to changes in the external environment.
If feeding and management are improper, it can cause the chicks to get sick and die in large numbers. The health of the chicks also has a direct impact on the fattening of the broilers in the later stage. Only by cultivating high-quality chicks can the broilers grow rapidly and improve the quality of the chicken.
Brooding often faces a series of problems, which affect the effect of brooding. Only by rationally analyzing the problems faced and adopting corresponding countermeasures can a good breeding effect be achieved and the economic benefits of broiler breeding can be improved.
1.Broiler brooding problems
The grouping is unreasonable.
Unreasonable grouping is one of the most important problems that broiler breeders often face. Reasonable group breeding is conducive to the growth and development of chicks, and many farmers have ignored this problem. The physique of broiler chicks are not the same when they are born. If they are not reared in groups, raising chicks with stronger physiques and chicks with weaker physiques in the same group will result in weaker chicks not being able to grab feed. The problem of unbalanced eating has resulted in stronger chicks with stronger physique, and weaker chicks with weaker physique. If this unbalanced phenomenon continues for a long time, it will cause the quality of the entire broiler flock to decline, thereby affecting the breeding of broiler chickens.
The lighting is unreasonable.
Scientific and reasonable light can effectively accelerate the growth and development of broilers, provided that it can be achieved under a certain light intensity. However, some farms did not notice the relationship between light intensity and growth rate of broilers. Reasonable light includes reasonable light time and light intensity. Only when both are scientific and reasonable can it play its due role. The rapid growth and development of broiler chickens also need good body rest. If the light is too long, it will affect the rest of the broiler, and the broiler cannot have a good sleep, which will inevitably affect the growth and development of the chick. Reasonable light intensity can speed up the growth rate of broiler chickens. The light intensity used for raising chicks should not be too strong or too weak. Too strong or too weak light will not only not promote the growth and development of broilers, but sometimes even has a counterproductive effect. Not good for weight gain. Therefore, whether the lighting is reasonable is another problem faced by broilers during brooding.
Improper feeding time and method.
So far, there is no way to completely solve this problem, because young chickens are different from adult chickens. Adult chickens can eat at will, while young chickens cannot. Therefore, the chicks have stricter requirements for the time of feeding feed. For example, unsystematic and unreasonable arrangement of feeding time during the brooding will result in insufficient feed intake of the chicks, and even the phenomenon of not wanting to eat. The most direct consequence of this is that most of the chicks cannot develop normally, and it will indirectly lead to an increase in the mortality of the chicks. Some farms have lost money or even closed down when raising broilers. It is likely that a large part of it is because the chicks did not arrange the feeding time properly after the start of the feed, and did not adopt a reasonable feeding method.
2.Solutions
The time when the chicks are born just after their shells are different, this will cause the chicks to have physical differences before brooding. To solve this problem, a staff member can watch when the chicks come out of their shells. Note that chicks born at different time periods cannot be kept together, and chicks of different physiques should not be kept together. In this way, the growth and development of the chicks in the initial stage will be consistent, and the differences between groups will not be too great, avoiding the phenomenon that the strong are stronger and the weak are weaker.
Aimed at this situation when the illumination is reasonable. In the process of feeding and management of chicks, attention should be paid to providing scientific and reasonable light. There must be certain standards for the length of the lighting time and the level of light intensity, and it must be implemented in strict accordance with this standard. Chickens are very sensitive to light, and light plays an important role in the growth and production performance of chickens. Reasonable light can increase the activity of broiler chickens, improve the health of broiler chicken legs, and reduce the occurrence of paralysis. It can also reduce the early growth rate of broilers and improve the cardiovascular function of broilers, thereby reducing the incidence of ascites and sudden death syndrome. The principle of providing light to broiler chicks is to change the intensity from strong to weak, and to increase intermittent light. During the first 3 days of brooding, keep the light for 24 hours. The light intensity should be such that the chicks can eat and drink normally. Keep the light well, but the intensity should not be too high, otherwise it will easily cause pecking. In the future, the light time can be gradually reduced, and the light intensity will be reduced to half on the 10th day of brooding.
It should be noted that ensuring that the lights are not turned off within 12 hours after immunization can effectively reduce the chance of immune stress. After the broilers are 36 days old, use low light for 24 hours or turn off the lights for 2 hours every day, so that the chickens can fully eat the feed, to reduce the feed-to-meat ratio and increase the growth rate.
After the chick is born, it mainly obtains energy and nutrition from the yolk sac in the body. But it can only last for a short period of time, so the chicks must be fed and boiled after they are born. Generally boil the water first and then start the food. However, it should be noted that although the chicks need to be filled with certain nutrition after birth, they should not be fed as soon as they are born, otherwise it will cause the chicks to lose their appetite.
Autumn is a difficult season for brooding. Doing a good job of brooding in autumn can greatly improve economic benefits. Prevention of diseases in autumn brooding is the focus of work, so the sanitary cleaning work in the pens should be strengthened, and the pens should be disinfected every day. Especially after each batch of chickens is released, before new chicks enter the house, disinfection of the empty house should be done. During the brooding stage, it is necessary to strengthen environmental control and maintain proper temperature, humidity and air quality. Only in this way can the chicks grow fast and healthy.
