People who use chicken equipment need to strive to do the following five points!

For those who use the equipment to raise chickens, the profit of raising chickens in that year is not only affected by the price of chickens in that year, but also by the cost of raising chickens themselves, such as the cost of feed, the survival rate of chickens, we can save the cost of feed as much as possible, but the survival rate of raising chickens needs us to learn from experience to improve. So today's chicken equipment will share with you five necessary conditions to improve the survival rate of chicken seedlings when using chicken equipment.
1. First of all, we should do a good job in the proportion of nutrition feed
In order to reduce the feed cost and ensure the normal growth and survival rate of the flocks under the condition of meeting the nutritional standards of the flocks, the breeders should select the reasonable feed ingredients according to the nutritional requirements of the layers and broilers at different stages, pay attention to the quality of the feed, the fresh and Moldless feed materials and the storage of the feed.
2. Create conditions suitable for the growth of chicken seedlings
The temperature of the henhouse controlled by the breeders in the process of raising is very important to the growth and survival rate of the chicken group, especially the management of the henhouse temperature. When the ambient temperature changes, when it exceeds a certain limit range, it will cause the disorder of metabolism, the inhibition of immunity and even death of the chicken. Therefore, it is very important to control the temperature for the growth and survival rate of the chicken group. The farmers should pay attention to the reasonable control according to the temperature required by the egg broiler and different growth stages.
3. Do a good job in drug control of chicken seedlings
To improve the survival rate of chickens is to reduce the prevalence rate of chickens, so all aspects of prevention work are very important, drug prevention is very important, most bacterial diseases rely on the timing of drug delivery to achieve the purpose of prevention. The bacterial diseases and parasitic diseases prevalent in spring mainly include colibacillosis, salmonellosis, chronic respiratory diseases, coccidiosis, etc., and most of these diseases are closely related to the change of age and environment, which requires different drug prevention procedures based on different situations.
4. Ventilation of chicken house
The ammonia, carbon dioxide and other harmful gases in the henhouse will seriously affect the health of the chickens, reduce the survival rate of the chickens, and reasonable and effective ventilation can remove the harmful gases from the henhouse and supply fresh air for the henhouse. Therefore, the ventilation operation of the henhouse is very important, especially when breeding in winter, the farmers should not only think about heat preservation, but also do a good job of cold prevention Heat preservation, and pay attention to ventilation.
5. Cleaning and immunity of chicken house after changing batches
Immunization should pay attention to Newcastle disease (at least two times of immunization, three times of immunization) and influenza. (H9 is necessary to avoid it. H5 is recommended when it is serious. I suggest that it should be avoided. It is better than that). It is better to get rid of the disease early (1 days earlier). The immune function is eyedrop, nasal drip and subcutaneous injection (broiler's influence on the quality of chicken is not initiated by intramuscular injection), the spray is relatively reliable, the immune gap and problems of drinking water are still many, but many chicken farms are just accustomed to drinking water immunity.
The above five points are the five necessary conditions for us to ensure the survival rate of chickens. The market price is not something we can control, but the cost of raising chickens and the survival rate of chickens can be determined by us. Therefore, we should do the above five requirements well and try to improve the survival rate of chickens.
