7. The main methods suitable for large-scale chicken raising are plastic shed, cage and mountain chicken raising<
chicken raising in plastic greenhouse:
this is a chicken raising method with less investment, quick effect and high income, which is worth popularizing and applying in the chicken raising households who are just engaged in chicken raising instry and have poor economic conditions
advantages of raising chickens in plastic shed
convenient materials: the main materials of chicken house in plastic shed are ordinary agricultural film, bamboo and straw curtain, which are easy to obtain except film. It can be built on demand, not compete with agriculture for land, and can combine agriculture with animal husbandry, raise chickens to fatten the field, rece environmental pollution, and at the same time, it is also convenient for the complete disinfection of sheds and the eradication of pathogens
low cost: generally, the construction of chicken house needs about 30 yuan for each chicken, and only 4 yuan for this method. Moreover, it is easy to build, time-saving and labor-saving. It can also make full use of other existing free greenhouses to raise chickens, and it is convenient to manage, which can improve the survival rate. The average brooding rate and breeding rate are 98% and 96% respectively. One greenhouse only needs to raise three batches of chickens to recover the investment
sufficient light: e to the translucent characteristics of plastic greenhouse, large area and long time of natural light, it is concive to improve the survival rate, accelerate the growth rate and rece feed consumption
good heat preservation: this advantage is particularly prominent in winter, which can improve the laying rate of hens and the growth rate of broilers<
cage chicken breeding:
this kind of chicken breeding method has the advantages of high feeding density, convenient artificial control of feeding conditions, stable laying rate, high yield, fast weight gain of broilers, relatively less material consumption, space saving and bedding material saving, and is also welcomed by procers<
raising chickens in mountainous areas:
it is to raise domestic chickens by using natural green fodder and animal fodder such as insects in Grass Mountain, grass slope, orchard, woodland and barren beach. It has the characteristics of good isolation condition, less disease, high survival rate and less investment. It not only reces the feeding cost, but also increases the game. The chicken has unique flavor, good quality, no fishy smell and delicious taste, which is popular with consumers. Therefore, it is a good way to get rich with good price and high benefit
the main technology of this kind of chicken breeding is mainly introced as follows:
breed selection
the characteristic of mountain chicken breeding is grazing. In breed selection, local chicken or local hybrid chicken with suitable grazing and strong disease resistance should be selected, such as Taoyuan chicken, Xianju chicken, Gushi chicken, Xiaoshan chicken, Zhuanghe chicken, Sanhuang chicken, Xinghua chicken, Yangshan chicken, Qingyuan Chicken, Sanhuang beard chicken Zhongshan Shalan chicken, Xinyi Huaixiang chicken, Guangxi chicken and other local fine varieties. They are resistant to roughage and have strong disease resistance. Although they grow slowly and have low feed reward, they have delicious meat, high price and high profit, so they should be the first choice for mountain breeding
shed construction
site selection. Whether the site selection of mountain chicken breeding is appropriate or not is related to the health and epidemic prevention, the growth of chickens and the work efficiency of breeders, as well as the success or failure and benefit of chicken breeding. Site selection should follow the following principles: (1) it is not only concive to epidemic prevention, but also convenient transportation 2) The site should be high, dry and well drained 3) There should be shading equipment in the site to prevent sunstroke or cold in the rain 4) The site should be provided with water and power supply, and can be enclosed to prevent losing and bringing in germs. The grass slope is windward and sunny, with flat terrain and no ponding. It's best to have trees so that chickens can enjoy the cool in the shade
methods of building shed. The requirements of chicken house design are: ventilation, dryness, warm in winter, cool in summer, sitting in the north and south. Generally, the shed is 4-5m wide, 7-9m long, 1.7-1.8m high in the middle and 0.8-0.9m high on both sides. It is usually covered with three layers of linoleum, straw and film from inside to outside to prevent water and heat. On both sides and one end of the shed roof, sand bricks and stones are used to press the film felt, and an entrance and exit are opened at the other end to facilitate the access of breeders and chickens. The main support of the shed is pulled firmly with iron wire in four directions to prevent the shed from being overturned by storm
clean and disinfect the shed. After each batch of chickens are put on the market, the chicken shed should be thoroughly cleaned, the surface soil on the ground should be replaced, and the cleaning tools should be used. The floor and utensils in the shed were first sprayed and soaked in Suhl solution by 3%-5%, then fumigated and sterilized, with 25 milliliters of Faure Malinga 12.5 grams of Potassium Permanganate per cubic meter space. The grass hill and grass slope where chickens were originally raised should also be sprinkled with a layer of hydrated lime on the ground first, and then sprayed for disinfection. The best way is to build a new shed with pollution-free grassland
lay bedding grass. In order to keep warm, we need to lay some bedding. The bedding material should be fresh, pollution-free, soft, dry, strong absorbent sawst, small shavings, straw, chaff, etc., which can be mixed. Before use, the bedding material should be exposed to the sun to pick out the moldy bedding grass. The thickness should be 3-5cm
feed selection
generally speaking, the growth speed of high-quality native chicken is slow, and the requirement of feed nutrition level is relatively low, but it can not only feed a single feed, so as to avoid the lack of nutrition, affect the growth and development, and rece the survival rate. We should choose high quality native chicken series full price pellet or mixed feed. In addition, pumpkin, sweet potato, cassava and other grains planted in mountainous areas can be used to replace part of the mixture<
chicken feeding management
the growth and development characteristics of chickens are poor thermoregulation, fast growth, imperfect digestive function, poor disease resistance, strong sensitivity, gregarious and timid. Therefore, we should pay attention to the following points in feeding management:
drinking water and eating. After the chicks enter the brooding room, they can rest for half an hour to one hour to feed water. Generally, feeding water is prior to feeding. The water temperature should be around 32 ℃, and you should not drink cold water. The first two days can drink dilute concentration of potassium permanganate solution, which is concive to anti-inflammatory, sterilization, prevention of chicken dysentery. After drinking water, chicks can quickly excrete meconium to stimulate appetite. Generally, you can eat after drinking. Sprinkle the open feed on the light colored plastic cloth spread on the bedding to let the chicks eat freely. The digestibility of chicks is poor, so it is necessary to feed them with digestible and nutritious feed. The chicks had a good appetite after 2 days. When feeding, it's better to feed 80% full. Overeating can cause indigestion; When it is not enough, it will affect the growth and development of chicks, and even cause pecking addiction. The best feeding amount is 15-20 minutes
ambient temperature and humidity. The key of brooding is to give chicks suitable temperature. Take the temperature under the brooder as an example: 34-35 ℃ at 1-2 days of age; 3-7 days old is 32-34 ℃; The second week was 30-28 ℃; The third week was 28-26 ℃. During the brooding period, the temperature dropped by 2 ℃ every week in winter and spring, 3 ℃ every week in summer and autumn, and dropped to 21 ℃. The relative humidity of chicks was 70% - 75% in the first week, decreased to 60% in the second week, and kept at 55% - 60% after the third week. Too high humidity is concive to the reproction of pathogenic microorganisms, and easy to ince coccidiosis. Too low humidity and dryness will accelerate the respiration of the chicks, and a large amount of water in the body will be distributed with the respiration, and the remaining yolk in the abdomen will not be absorbed, which will affect the development of the chicks
pay attention to grouping and strengthen inspection. The strong and weak chicks and sick chicks should be raised in groups. It is better to check the weak chicks when they are fed for the first time in the morning. The weak chicks are easy to be squeezed out. The seriously ill chickens should be eliminated immediately. The significance of regular inspection of chicken flocks is as follows: first, understand the palatability and feeding amount of feed through observation; Second, it can discover and diagnose diseases from diet, activity and fecal state of chickens in time; The third is to discover and deal with accidents in time to rece losses
feeding and management of growing chickens. The purpose of feeding is to make the chicken fully develop and lay the foundation for later fattening. The feeding mode is grazing combined with supplementary feeding. Generally, we should pay attention to the following two points:
hens should be raised in groups. Generally, the feather of rooster grows slowly, has strong fighting ability, has high utilization rate of protein and lysine, and has high feed efficiency. Due to the difference of endocrine hormones, hens gain slowly and feed efficiency is poor. Separation of male and female is helpful to improve the uniformity. During the growth period, the feed was put in the trough or directly sprinkled on the ground, once in the morning and once in the evening, until full
to expel insects. Generally, after 20-30 days of grazing, the first anthelmintic should be carried out, and the second anthelmintic should be carried out after 20-30 days. It is mainly to expel the internal parasites, such as Ascaris lumbricoides, tapeworms, etc. Qusuanling, levamisole or albendazole can be used. For the first time, each chicken was treated with half a tablet of qusuanling. For the second anthelmintic, each chicken was given 1 tablet of qusuanling. The tablets can be taken orally at night or ground into powder, and then mixed with the feed for feeding. We must carefully mix the medicine and feed evenly, otherwise it is easy to proce drug poisoning. The next morning to check the chicken manure, to see if there are insect body discharge. And to clean up the chicken manure, in order to prevent the chicken pecking insects. If there are alt worms in chicken manure, the same amount of insecticide can be used to drive the worms once the next night
fattening chicken feeding management
that is, the period from 10 weeks old to market. The main points of this period are to promote the deposition of fat in the body of chickens, increase the fat of broilers, improve the meat quality and the luster of feathers, so as to achieve timely marketing. We should pay attention to the following three points in feeding and management: first, with the growth of Broilers' age, the main tissues of growth in the body are very different from those in the middle stage. Appropriate fat deposition can improve the meat quality of Broilers and enhance the aesthetic feeling of carcass appearance. In this period, the metabolizable energy of the diet should be increased and the protein content should be relatively reced. The energy requirement of broilers in fattening period should reach 12.54 MJ / kg and the crude protein content should be about 15%. In order to achieve this level, it is often necessary to increase animal fat. On the one hand, it can make chickens feed on natural insects, leaves and weeds to save feed; On the other hand, improve the meat flavor of chicken, make the appearance and meat quality of listed chicken better. In the period of fattening, we should rece the range of activity and movement of chicken, in order to benefit fattening. Third, we should do a good job in epidemic prevention and attach importance to insecticidal, rodent killing, cleaning and disinfection. To prevent disease
disease control
there are many reasons for chicken disease, such as improper feed mix, too high or too low temperature, stress and trauma; Chemical factors, such as drug overdose, ingestion of pesticides, inhalation of harmful gases, etc; Biological factors, mainly the invasion of pathogenic microorganisms. Therefore, we should pay attention to the following points in disease prevention and control:
firmly establish the view that prevention is more important than treatment. The incidence rate is high, the mortality rate is high, the cost is high, and the benefit is low.
establish the viewpoint of disease prevention and control with vaccine. This is the most important, effective and economical measure to prevent and cure diseases. Most major infectious diseases can be prevented by vaccination. Whether the vaccination is successful or not is directly related to the maternal antibody, vaccination method and vaccination time of chickens. Therefore, different farms have different immunization proceres
set up the viewpoint of comprehensive prevention and control. That is to say, all links from farm construction, seedling introction to feeding management should be considered from the perspective of epidemic prevention, which is the general requirement of epidemic prevention rules and the basic requirement of instrialization and intensification of chicken instry

8. There are 13 chicken farms in Chizhou, Anhui Province
9. On the one hand, the nitrogen content of chicken manure is high. On the other hand, e to the extensive use of antibiotics and other substances in the process of breeding, the pollution of manure is relatively serious. At the same time, the odor of the air discharged from the chicken house is heavy, which affects the livelihood of the surrounding residents.
