What are the taboos for raising chickens?

(1) Co-breeding of ducks and geese is prohibited. In order to save space, some farmers put chickens, ducks and geese together for polyculture, which is unscientific. First of all, polyculture can easily lead to the spread of epidemics. For example, ducks and geese can also be infected with Newcastle disease virus. Under normal circumstances, the virus lurks in ducks and geese and becomes a carrier without showing any symptoms. If mixed with chickens, it is easy to transmit the virus to chickens, resulting in Newcastle disease. Secondly, mixing chickens, ducks and geese will reduce the utilization rate of feed, because they have different nutritional requirements for feed. If you feed with the same feed, it will inevitably reduce the feed utilization rate and waste feed. Third, ducks and geese cry loudly, and chickens like to be quiet. If mixed together, chickens will be frightened and affect their eggs. Fourth, ducks and geese are waterfowl. They like water and chickens like dryness. Chickens are prone to get sick when the breeding ground is wet and are not suitable for breeding together.

(2) Avoiding the use of red light in chicken coops will inhibit the growth of chicks and chicks in the development stage, delay their sexual maturity and lead to late childbearing; Red light can inhibit the sexual function of breeder cock and make the fertilization rate of breeder eggs low. Therefore, red light should not be installed in chicks, chicks and henhouses that produce eggs.

(3) The breeder should not change the coat frequently. Chickens get used to the color of the breeder's clothes, and they will have a sense of intimacy. As soon as the breeder enters the henhouse, it will arouse the spirit of the chicken, enhance the appetite and increase the feed intake. If the breeder suddenly changes the color of the fur, the chicken will be frightened, fidgety, lose appetite and eat less. Therefore, breeders should not change their hair frequently, and try not to let outsiders into the henhouse to avoid artificially reducing production.

(4) Calcium supplementation Avoid feeding raw eggshells. Some farmers are used to feeding chickens with raw eggshells in order to supplement calcium for chickens, promote production and lay more eggs. As everyone knows, the effect is just the opposite. Because bacteria and viruses are often attached inside and outside the eggshell, chickens are prone to gastrointestinal diseases or infectious diseases after eating them.

(5) It is forbidden to vaccinate chickens during the peak laying period, and the physiological changes of their functions have certain rules. At this time, if chickens are vaccinated or vaccinated, their laws will be disrupted, which is the decline in egg production or respiratory diseases. Moreover, chickens do not have a quiet environment during the laying period. Injecting chickens will cause stress syndrome because of fear, resulting in less eggs and loss of appetite. It is best to vaccinate chickens before or after production.

(VI) Insecticidal Prohibition of Trichlorfon Trichlorfon is a broad-spectrum animal repellent, which is safe and effective for domestic animals such as pigs, cattle and sheep, and should be banned for chickens. The reason is that trichlorfon is an organophosphorus drug, and most of chicken crops are in alkaline environment. Trichlorfon can produce highly volatile dichlorvos in alkaline liquid, and its toxicity is more than 10 times that of trichlorfon. Chickens are most likely to be poisoned after eating trichlorfon. When chickens are deworming, they can choose deworming spirit or levamisole tablets, and the effect is very good.

(VII) Disinfectants are forbidden during the immunization period. Some chicken farmers use disinfectants to drink water and mix materials during the immunization period, which leads to immune failure, chicken disease and serious economic losses. Disinfectants such as disinfectant, strong iodine, antibacterial agent, compound phenol, etc. It has a strong killing effect on a variety of pathogenic microorganisms in the henhouse environment and chicken flocks, leading to immune failure. Therefore, the disinfectant should be stopped two days before and after the chicken house immunization.

(8) The main component of plant ash plant ash is potassium carbonate, which easily reacts with chicken manure to generate ammonia gas. Directly stimulating the respiratory tract of chickens can increase the secretion of respiratory tract, hinder the growth and development of chickens and reduce the laying rate. In severe cases, it can cause acute diseases such as laryngeal edema, necrotizing bronchitis, pulmonary hemorrhage and even death.
