What problems should we pay attention to when raising broilers in cages?

Several problems that should be paid attention to in cage rearing of broilers;

First, breeders should adopt the method of expanding the population by stages, that is to say, brooding will be concentrated in a small area at the beginning of breeding 2 1d, which can effectively save heating costs, and then gradually expand the population after 21d.

Secondly, the breeder should study and design the corresponding reasonable and scientific feed formula according to the nutritional components needed for cage-raising broilers to meet the growth and development needs of chickens under this high-density cage-raising condition.

Yes The vitamins in the feed formula are increased by 20% on average compared with the standard of flat feeding on the ground, which is suitable for the needs of caged broilers.

Thirdly, the lower half of the front net of the henhouse is designed to be pear-shaped when the breeder wants to brood, and then the baffle is adjusted to meet the whole feeding demand of commercial broilers.

Fourth, breeders should pay attention to the fact that the henhouse where broilers are kept must be completely closed and there can be no windows. The air in the henhouse should be exhausted by an exhaust fan, and fresh air should enter the henhouse through the air inlet. Artificial light is used in chicken coops.

Light instead of natural light. When the temperature is high, a wet curtain should be installed in the henhouse to cool down, while in the cold season, the temperature in the henhouse can be kept in a comfortable range by artificial heating or the heat of the chicken itself.

Inside.

Fifthly, the material and structure of cage bottom should be improved, so that the incidence of breast cyst in broilers is greatly reduced, and the incidence of breast cyst is less than 7.5%.

Nine Common Mistakes in Feeding Broilers

It is easy for breeders to have some wrong ideas when raising broilers in cages! It is easy to make our breeding work get twice the result with half the effort, not worth the loss! So when we are engaged in aquaculture, we must pay attention to these mistakes to avoid them!

Introduction of 9 Mistakes Easily Made by Caged Broiler Farmers

Error 1, do not pay attention to feces disposal.

Better farmers dispose of the manure or sell it away from the shed. Some farmers directly pile feces outside the shed, or even pile feces in the windward direction of the shed. There are hundreds of millions of pathogens in 1g feces, and since most feces are excreted from adult birds, these pathogens may have no clinical symptoms or only slight negligible clinical symptoms in adult birds, but they may be fatal to young birds, such as salmonella and viral diseases. Therefore, it is very important to do a good job in the harmless treatment of feces. The best way to treat feces is to stay away from chicken coops or take measures such as sealing and composting to kill pathogens.

Mistake 2, careless disinfection or improper use of disinfectant

Environmental disinfection is ok for most farmers, but some farmers pay little attention to fumigation and chicken disinfection. Fumigation and disinfection before entering chickens is the most comprehensive disinfection method, and disinfection with chickens when there are explosive diseases around is the most effective method to reduce the pressure of infection. Experiments show that when diseases occur in the same chicken farm, the diseases in the henhouse where chickens are disinfected every day are lighter, while the diseases in the unsterilized henhouse will be very serious. For the choice of disinfectant, farmers have always used a disinfectant and never changed varieties, but they don't know that pathogens will gradually develop resistance to disinfectants, which will reduce the effect of disinfectants. Therefore, at least three disinfectants should be prepared to be used in rotation to avoid the reduction of disinfection effect. At the same time, after multiple batches of infection of the same disease or the outbreak of serious infectious diseases, it is necessary to change disinfectants and use products with good disinfection effect to avoid the same pathogen infecting large groups again.

Mistake 3: Do not pay attention to aquaculture management

Related to this, once the breeding benefits decline, farmers are most likely to blame the poor quality of chickens or poor feed, or improper treatment by medical veterinarians. It is true that the quality of chicken is a more important factor. It should be noted that only careful management can keep chickens in a healthy state all the time, fully absorb feed, and finally give full play to the maximum production performance of chickens. What's more, when chickens are sick, some management aspects (such as temperature, nutrition, drinking water, etc. ) all require more details. No matter how good the drug is and how reasonable the treatment plan is, if the management can't keep up, it won't play its due therapeutic effect.

Mistake 4: One-sided pursuit of eating more materials

In the later stage of normal breeding (for example, after the age of 30 days), many farmers will ask "Are there any products that can increase food intake", which can be explained from two aspects. At present, the feed intake of fast-growing broilers will have certain feed intake standards according to the actual situation of feed, and each factory will have corresponding guidance. On this basis, it will increase or decrease due to individual or seasonal differences, but it will not exceed 15%. On this basis, if the feed intake of chickens decreases after the onset, the way to increase the feed intake is to treat the disease. During the treatment, certain food additives can be used according to the condition, which are basically products to improve gastric motility and resistance. This increase in food intake has certain significance, but if a large group of people are normal and the food intake is within the guidance range, it is of little significance, because at this time, the food intake can also be increased by improving gastric motility or drugs acting on the nervous system. Because the body has reached the best absorption of feed, eating more at this time may not necessarily lead to more meat, and sometimes it will be made or wasted. Under normal circumstances, you can regularly feed health care products with high conversion rate to improve the ratio of feed to meat, such as live bacteria preparation for 2 ~ 3 days a week.

Error 5. Give medicine every day, and don't worry if you don't feed it.

This is very common in the current breeding process. The reason is that there are too many and complicated diseases at present. Farmers hold the idea that "at least I tried to prevent the disease by taking medicine, which means the disease is very serious, but if I don't take medicine, I will regret not taking it" and adhere to the principle of "no regret", so I basically take medicine every day. It should be noted that "drugs have three kinds of toxicity". After the drug is used, it not only acts on pathogenic bacteria, but also most antibiotics will kill some normal flora in the intestine, which plays a great role in the decomposition and absorption of feed. After being killed, the feed conversion rate will decrease. This is why we say "it is difficult to gain weight during the administration". Generally speaking, when a large group of people are in a mental state, eating and drinking water, and acting normally, there is no need to take drugs. What needs to be done is to do a good job of disinfection, and to use health care products to improve the body's resistance and reduce the incidence. Chickens can grow well only if they are less sick.

Error 6. Diagnose yourself and treat yourself.

Some farmers have been breeding for a long time, and they have learned a lot about diseases through their own study, and they are no strangers to anatomical lesions. Besides, they used drugs in the past, so they went to see a doctor and used drugs themselves. Unless you have systematically studied the relevant theoretical knowledge, you should still listen to the opinions of veterinarians, because there are too many diseases with the same lesion, so you need to make corresponding identification and exclude diagnosis; Moreover, each drug has its own symptoms, pathological changes and methods of use, which may not be symptomatic or fail to exert the best effect of the drug.

Error 7. Neglect stress prevention

At present, stress is almost everywhere in the breeding process, and the most influential are epidemic stress and temperature difference stress of soft-shelled turtle. Farmers all know that taking drugs to prevent immune stress after using vaccines, but ignore that catching chickens during immunization is also a stress behavior, so it is recommended to take drugs to prevent stress 4 hours before using vaccines (except drinking water immunization); The main reason for temperature stress is the excessive temperature difference (which can be obvious when it exceeds 6℃). Most farmers can insist on watching the weather forecast, and they can take anti-stress drugs for 2 hours at night to alleviate the possible stress reaction when they know that the temperature will change greatly in the future. Vitamin C can be used as a stress drug and should be drunk within two hours.

Error 8. Think the vaccine doesn't work.

The most puzzling thing for farmers is "I have used the vaccine, how can I get sick?" . At present, the protective power of any vaccine can not reach 100%, and the concept of vaccine use is to reduce the incidence probability to infinity and close to zero; Due to many factors, such as missed immunization or insufficient vaccine dose, the existence of virulent and mutant strains, low antibody level, decreased body resistance and so on, the protective power of vaccine is different from the actual situation, and corresponding diseases will break out when there are virulent and mutant strains infected. So there will be diseases after immunization. We should not simply blame the vaccine, but find the real cause of the disease. Vaccine is the first choice to prevent viral diseases.

Nine mistakes. Accept the new concept of agriculture

More and more standardized farms have accepted the concept of natural and healthy farming. This concept advocates that chickens should grow naturally in a healthy environment to give full play to their due best production performance; Its foundation is that chickens only have good resistance; Its guarantee is to provide a healthy breeding environment through refined management; The way is to adopt strict disinfection and use various health products (such as interferon, antibacterial peptide, immune peptide, enzyme preparation, microecological preparation, etc.). ) to rebuild the body's natural defense system and make chickens less sick, instead of taking medicine all the time to prevent it. Because chickens have high resistance in a healthy environment, they can also create the greatest production benefits.
