Analysis on the feeding management of broilers
The number and size of broiler chickens raised in broiler battery cages is growing at an alarming rate. The density of cultivation per unit area is large, and the management level of the breeders is higher than that of the net culture. In fact, no matter what farming mode and breeding conditions, we manage. The primary task is to manage the chickens so that the chickens have a comfortable living environment so that the chickens do not get sick or get sick.
1. Strict control of temperature, ventilation and humidity
Appropriate temperature, light and good ventilation are especially important for the growth of caged broilers. Therefore, in the actual feeding process, it must be strictly controlled. About temperature control. The demand for temperature varies during the different stages of broiler growth. Generally speaking, before brooding, it is necessary to keep warm in advance, and raise the temperature in the house to 26 °C; in the brooding period, the method of high temperature brooding is adopted, and the temperature usually needs to be controlled at about 33 °C, and then it is lowered by 0.5 per week.
Control about ventilation. During the brooding period, because the temperature in the house is relatively stable, we usually realize the ventilation and ventilation in the house by controlling the opening and closing of the fan. About the control of humidity. The humidity control in the brooding period is preferably 60-65%. Increasing the humidity in the house can be achieved by placing several water-filled basins in the house and increasing the humidity in the house by evaporation. Increase the humidity inside the house. It is not recommended to sprinkle water on the ground or install nozzles to increase the humidity in the house. The humidity in the breeding house should be kept at 40-60%, and the suitable humidity is conducive to the normal growth of broilers.
Humidity should not be too high or too low. If the humidity is too low, it will cause dehydration of broilers, poor growth of feathers, dry skin, and dust in the air, which may easily induce respiratory diseases. If the humidity is too high in summer, it will cause the evaporation and heat dissipation of the chicken body to be blocked, the feed intake will decrease, the drinking water will increase, and cause heatstroke. If the humidity is too high in winter, the chicken body will lose heat too much, the feed intake will increase, and the feed consumption will increase. This leads to an increase in the ratio of meat to meat and increases the cost of farming.
2. Do a good job of cleaning and disinfecting caged houses
The cleaning and disinfection of the chicken house and the chicken battery cages should be thorough, without leaving a dead angle. In particular, it is recommended that the caged broiler has a high breeding density. It is recommended to use spray or fumigation to disinfect. When disinfecting, pay attention to the use of disinfectant. Strictly control the dosage of the disinfectant. In addition, after the disinfection is completed, it is necessary to open the doors and windows in time, and do a good job of ventilation.
3. Equipment use
Large and medium-sized chicken farms have advanced equipment, but with advanced equipment, it is not always possible to raise chickens. With the scale and automation, the failure of farming is not uncommon. The key lies in the organic of people and equipment. In combination, the operator must not only be familiar with the principle of the equipment, but also observe it carefully. Because the temperature of the thermostat and the temperature of the house have a certain error, the error value should be adjusted to the minimum, so that the temperature of the house can be adjusted. The temperature at which the chicken is most suitable for growth. In addition, the operator must be proficient in the use of the equipment and the feeding procedures of the chicken at various stages, and can promptly discover and repair the failure of the equipment. Once the equipment is used improperly or the equipment fails, it will Caused huge economic losses.
Advantages of broiler cage equipment
The use of broiler cage equipment is common in many large and medium-sized chicken farms. Except for some farms that are used to free-range, most chicken farms choose to use broiler cage equipment as a device for raising chickens. The broiler cage manufacturers said that the use of broiler cage equipment can collect and manage chickens, save energy, and effectively reduce the incidence of poultry diseases. Let's talk about the advantages of broiler cage equipment.
1. High degree of automation: automatic feeding, drinking water, clearing dung, wet curtain cooling, centralized management, automatic control, saving energy, improving labor productivity, reducing the cost of artificial breeding, and greatly improving the breeding efficiency of farmers.
2. The flock is well-prevented and effective in preventing infectious diseases: chickens do not touch the feces, which can make the chickens grow healthier and provide a clean and comfortable growing environment for the chickens.
3. Save space and increase stocking density: The cage density is more than 3 times higher than the flattening density.
4. Saving farmed feed: caged chickens can save a large amount of farmed feed, chickens are kept in cages, the amount of exercise is reduced, energy consumption is small, and waste materials are reduced. The data show that cage farming can effectively save more than 25% of farming costs.
5. Rugged and durable: The caged broiler complete set of equipment uses hot dip galvanizing process, corrosion resistance, aging resistance, and the service life can be as long as 15~20 years.
How should the odor of broiler equipment in chicken farms be treated?
If the chicken farm does not clean the chicken manure in the chicken battery cages in time, the odor in the broiler equipment will be very serious, and it will affect the living environment of the chicken. Seriously, it will cause the chicken to become sick and affect the economic benefits. So what should we do?
1 padding deodorization
The sulphur is mixed into the litter to make the pH of the litter less than 7, which can inhibit the generation and emission of ammonia in the feces, reduce the ammonia content in the air of the house, and reduce the odor of ammonia. The specific method is to mix into the litter according to the amount of 0.5 kg of sulfur per square meter of ground, paving the ground.
2 ground odor
Sprinkle a layer of superphosphate on the ground in the house. The superphosphate reacts with the ammonia gas produced in the chicken manure to form an odorless solid ammonium phosphate salt, which can reduce the emission of ammonia in the feces of the house and reduce the odor of the house. The specific method is to evenly spray 350 grams of superphosphate on the ground of every 50 chickens.
3 air odor
The odor in the air is adsorbed by a substance having adsorption such as charcoal, activated carbon, cinder, or quicklime. The method is to use the net bag to load the charcoal and suspend it in the chicken house or properly sprinkle some activated carbon, cinder, lime, etc. on the ground, and the odor in the air can be eliminated to different extents.
The above is how to deal with the odor in the air of broiler breeding equipment. I hope that can help the chickens to better raise their chickens, and they clean up the chicken farm equipment in time to give the chicken a good environment.
How is the prospect of raising chicken in the countryside?
How is the prospect of raising chicken in the countryside? How can rural chicken raise sales? In rural areas, every family in the yard is accustomed to raising a few chickens. Because chickens are relatively good for poultry, many farmers directly use chickens as their main business and set up chicken farms. The first step in raising chickens to make money is to solve the problem of marketing. Some chicken farmers have good chickens, but they can't find a good market and they don't have a large price.
Native Chicken Breeding Has a Bright Future
As consumers are increasingly demanding food quality, consumers have chosen green and natural ways to grow and raise farm products. Green consumption has become a trend. In the case of loose-breeding chickens, many eco-random chicken farms have emerged throughout the country, and various chickens such as pheasants, black-bone chickens, Taishan chickens, reed chickens, and northern Jiangsu grass chickens have been free-ranged in accordance with natural methods. The average chicken meat is 1-2 times, and the price of the soil eggs is several times that of ordinary eggs.
Analysis of the causes of chicken cold
Cooling is one of the main causes of chicken sickness. There are many cold spots. It is not only the temperature control level or the ventilation of the chickens, but the factors that can cause the chickens to be cold are as follows.
1. During the brooding, the water line is too low, the water pressure is too large, the chicks are drilled into the water cup, the nipple leaks, causing the chicken feathers to be wet; the spray equipment is damaged, the nozzle dripping seriously or the spraying time is long, causing the chicken feathers to be wet.
2. Improper humidification method, only pay attention to humidification, does not consider the temperature of the flock, when the flock performance temperature is low, humidification with a humidifying tube will make the flock cold.
3. The chicken house is not tightly sealed, causing side windows, sewage outlets, chicken outlets, water curtains, exhaust fan outlets, etc., resulting in thief winds, so that the chickens in this area are cold due to low temperatures.
4. After the wind enters the chicken poultry farming equipment from the air inlet, there are obstacles blocking during the pre-warming process, causing the breeze to rebound, and the chickens are swollen.
5. The temperature control is unreasonable; the cooling rate is faster, especially in the cold season, which makes the chicken's cold is more common.
6. Only rely on the temperature indicated by the thermometer, but the chicken's physiological behavior is not taken seriously, resulting in the chickens being cold.
Factors affecting the water requirement of chickens when using broiler cages
① Production performance: The higher the production level, the greater the water requirement of the chicken. For example, adult chickens drink more water than chicks; among chickens of the same weight, young chickens develop water deficiency faster than adult chickens; laying hens drink more water than non-laying hens.
② Feed structure: Some feeds such as rye, bran and certain minerals such as table salt can cause chicken loose stools, so the water requirement increases. Excessive protein levels in the diet can increase drinking water. Because too much nitrogen in the chicken must be excreted from the kidney, and the chicken has the worst concentration of urine, it is necessary to increase the drainage to excrete more nitrogen, thereby increasing the water requirement. The increase of crude fiber content in the feed and the increase in the amount of feces in the chicken also increase the water requirement.
③ Ambient temperature: Under the production conditions of broiler cages, due to changes in the ambient temperature, the amount of water consumed by the chicken has changed significantly. High temperature (above 30℃) usually increases the amount of drinking water. When the ambient temperature increases by 1°C, the amount of drinking water can increase by about 7%; when the temperature is low (below 10°C or less), the amount of drinking water decreases. When the temperature of laying hens is increased from below 10℃ to above 30℃, the drinking water volume can be doubled. In addition, the temperature of drinking water can more affect the amount of water consumed by chickens. Chickens like to drink cold water instead of drinking water above ambient temperature, and refuse to drink water above 45℃.
④Water quality: When using broiler cages to raise chickens, chickens have strict requirements on water quality. There are fewer impurities in the water, and the pH is between 6.0-8.5. If there are more impurities in the water, especially when the water contains more soluble minerals, it will cause the chicken's palatability to the water to be reduced, thereby reducing the amount of drinking water. In addition, the use of certain drugs in water can also reduce the amount of water consumed by chickens. Therefore, chickens should be given fresh, cool and clean drinking water.
A Reasonable Broiler House Layout
A reasonable structure of the chicken house can provide a good living environment for the chickens including of equipment used in poultry farming, so that they can fully exert their production potential. Therefore, in addition to understanding the physiological characteristics of the chicken itself, the chicken house must be reasonably planned and constructed.
First, chicken layout considerations
1. The site should be chosen away from the residential area, convenient transportation, and far from the road.
2. The terrain is dry and sunny. As far as possible, it is not blocked in winter, no wind in summer, and no water after rain. Large area, leaving room for development
3. Rich in water resources, no pollution, easy to access, sufficient power and protection
4. The structure of the house is practical and economical. It not only saves funds but also saves energy as well as about chicken cages for sale. Its orientation is in line with local natural and physiological conditions. It is well lit, easy to ventilate and easy to operate. It is good for summer heatstroke and cool, and winter is good for heat preservation and cold protection.
5. The layout of the premises should be reasonable, so that the production area is separated from the non-production area. The non-production area and the water source are in the upwind direction of the chicken farm. The dirty road and the clean road are separated and do not cross. The manure field is located in the downwind direction of the chicken farm, and the brooding Separated from the breeding house, the brooding house is located in the upwind direction of the chicken farm.
Broiler feeding management points of spring
1. Disinfection
The chicks are thoroughly cleaned and disinfected 5 days before entering the site, avoiding corrosive disinfectant such as caustic soda to prevent equipment damage, then fumigation with formaldehyde, and sealing the doors and windows. After 24 hours, the window is ventilated. Personnel must be strictly disinfected to avoid destroying the disinfection effect. The trough and drinking fountains are cleaned and disinfected. After the chicks arrive, the ground is cleaned every day to reduce the stimulation of the respiratory tract by dust and chicken fluff, and the chickens should be disinfected every other day. Several disinfectants can be used alternately, and the vaccination period should be avoided for more than 24 hours.
2. Temperature
There is a temperature difference between the three-layer chicken battery cages in the upper, middle and lower layers, and the lower the outdoor temperature, the greater the temperature difference. Brooding is generally at the highest level, because the highest temperature is the highest, which is conducive to saving heat. The chicks enter the field on the first day, the temperature is controlled at 33 ~ 34 ° C, but also according to the state of the chicks to adjust the temperature. When the temperature is suitable, the flocks are evenly distributed, active and active, and the appetite is strong; when the temperature is low, the neck is constricted and concentrated to the heat source. Squeeze each other, the body trembles; when the temperature is too high, the amount of drinking water increases, the appetite decreases, the breathing speeds up, and the neck feathers are soaked. In the first week, the temperature dropped to 30~C, and then decreased by 2°C every week. The density of three-dimensional culture was large, which was 1~2°C lower than the flattening temperature. It should avoid the heat stress and the food intake decreased.
3. Grouping
Three-dimensional cultured broiler chickens use the whole sports chicks. When the chicks are too dense, they should be grouped in time to ensure that the chicks are evenly weighted. The first group is usually 12 to 16 days old, and the group is too early. Because the body size is too small, it is easy to grow in the cage gap. Drilling also wastes space and wastes energy. The second grouping, at 25 to 28 days of age, adopts the principle of “remaining weak and not staying strong” when grouping, and the important young chicks are placed in the lower layer, and the weak chicks are left behind. In summer, due to high temperature, it can be properly caged in advance. In winter, due to the large temperature difference between the upper and lower layers of the cage, the poultry battery cages time can be appropriately postponed, and one more in the lower cage to reduce the temperature difference between the upper and lower layers.
4. Ventilation
The key to successful aquaculture is ventilation, reasonable ventilation, elimination of harmful gases, temperature control, and reduction of ascites, chronic respiratory diseases and colibacillosis. The density of the three-dimensional farming unit is large, so ventilation is more important. Within 24 hours after entering the farm, the chicks can be ventilated due to the large space of the whole sports. As the age of the chicken increases, the ventilation volume is gradually increased, and the position and size of the air inlet are adjusted. Day, night, cloudy, sunny, spring, summer, autumn and winter. It is necessary to constantly adjust in a timely manner to achieve the feeling of no smell, no glare, no oxygen deficiency and more comfort in the house, to create a good growth space for the chickens, enhance the body's disease resistance and reduce the occurrence of diseases.

Advantages and Disadvantages of Broiler Ground Thick-bed Feeding Slat
The broiler ground thick litter feeding refers to feeding 5-10 centimeters of litter on the ground of a strictly sterilized chicken house, and the entire period of growth of the chicken is fully maintained on the litter. The litter requires soft, dry, strong water absorption, is not easy to compact, does not mold, no pollution. During the rearing process, loosening of padding material, removal of wet litter, and addition of new litter should be made as appropriate.
Advantages: Suitable for broiler growth and development, slightly lower than the Internet temperature during the hot season. Usually do not remove the feces, do not change the litter, save time and labor; in the winter can use litter fermentation heat production and increase Shewen; chicks in the litter activity increased, reduced the incidence of earthworms. Easy to use, low equipment investment, low incidence of breast cysts, and low defective products.
Disadvantages: It requires a lot of litter, repeated investment. The management of litter is difficult. If the management is not good and the litter is wet, various diseases of the digestive tract and respiratory tract infections are prone to occur: such as E. coli, coccidiosis, and chronic respiratory diseases. Direct contact between chickens and feces, the incidence of coccidiosis increased, and other infectious diseases are prevalent. The contradiction between ventilation and heat preservation is prominent, and health management is difficult. Chicken manure use value is reduced.
The Breeding Density of Broilers
Farming baby chickens for baroilers adopts a combination of whole-house brooding and upper cage brooding. The number of broods per cage is only 25, and there is no problem of crowding. The rearing density of caged broiler chickens is related to the season. The summer stocking density is low, and the winter stocking density can be appropriately increased. Generally, 8-9 pigs are fed in each cage.
Under the conditions of adopting ground litter and keeping the animals online, chickens should be divided into several small groups within the house. The number of chickens per group should be between 200 and 300. When divided into groups, they should be weighed according to their size, physical strength, and public health. The mother carries on, the individual characteristic in each small group must be basically similar. The characteristics of individuals in the group are similar, which is conducive to the even development of the group and helps to increase the survival rate of the chicks.
