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.

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.

Reasons for dyspepsia in chicken houses

Nowadays, most farmers raise broiler chickens by using battery cage for broilers. It is convenient and quick to use automatic feeding equipment, and it also saves feed waste. But now, as the summer is about to pass, the autumn will follow, and the rain will be wet. Sometimes there will be a state of indigestion. In fact, there are many factors to consider for this problem.

 

Feed mold infection, mycotoxins can cause digestive diseases such as oral cavity, intestinal tract, causing indigestion, mycotoxin contamination including feeding mildewed feed, and pollution in processing, transportation and storage. Due to the hot weather, the oil is corrupted due to improper preservation, causing broilers to cause glandular gastritis, muscle erosion and enteritis. Free radicals or reactive oxygen molecules produced by fatty acids can affect their immunity, slow down growth, cause poor pigmentation and cause enteritis. Excessive fat addition can cause lubricative diarrhea.

 

 


The nutritional requirements of broilers are relatively high in chicken battery cages . The low content of crude fiber in the feed will result in unbalanced nutrition and excessive crude fiber, resulting in large feed intake of broilers and confusion of gastrointestinal function, which may also cause indigestion. Insufficient energy in the feed The broiler is eating for energy, not enough energy, increasing the feed intake of the broiler, causing other nutrients not directly absorbed and directly excreted, thereby causing indigestion.


It is necessary to know that broilers grow fast, especially the growth of internal organs is 35 days ago; because of the low anti-stress ability of broilers, the environmental requirements are higher. There is no regularity in broiler cage feeding, overeating, or stressing the chicken, or causing the chicken to experience low temperatures at a constant temperature, which can cause indigestion. 60% of broiler chickens are made of water, so there must be sufficient drinking water to meet the needs of the chickens, while some farmers do not pay attention to drinking water sanitation, drinking polluted water or degraded water, causing chicken indigestion.

 

How to raise broilers for moving chicken sheds? With the occurrence of irresistible factors from time to time, the use of the original fixed chicken house is often prone to significant economic losses. In order to avoid the limitations of the fixed chicken house, mobile chicken sheds have emerged in recent years. This kind of house construction can not only To meet the needs of farmers breeding chickens, the key to it can make up for the lack of fixed chicken house, easy to move.

The so-called mobile chicken shed is actually an easy-to-remove, easy-to-move hut built with bamboo, wood, and thin-film materials. The construction of the shed can be made on the spot: a bamboo or wood strip is used to build a length of 8 meters, a width of 1.2 meters, and a height of 2.2. The frame of the rice, with a door in the middle, a door with a width of 0.8 meters (without leaving windows on both sides), and using an old nylon net or fishnet to enclose and fix it around and at the top and covered with a thick black film. The floor of the chicken shed is laid with bamboo or branches at centimeter intervals, and then the bottom is raised with a brick to a height of 10-15 cm, and the moving chicken shed can be put into use. Each chicken shed should be placed on a grassy slope that is sheltered from the wind, has a flat surface, and does not accumulate water. It is best to use woods or orchards. Grasses are planted and sprinkled with sand.

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.

In many cases, because farmers do not properly grasp the knowledge of scientific feeding and management of chicken farms, it is easy to cause the early death of chicken farms, thus affecting the survival rate of chicks and further affecting the ultimate chicken efficiency. How do you scientifically avoid the early death of a chick when raising in poultry cages for sale.  

Drinking water must be timely: especially after long-distance transportation of chicks, be sure to drink water in time, otherwise it will cause dehydration. Take a free drinking method and drink 5% of sugar water for the first time.

The temperature should be appropriate. The chicks are sensitive to temperature and maintain a 35-32 reduction trend within 1-3 weeks after hatching, increasing with age, and decreasing 2-3 times per week thereafter.

The density should be appropriate. if the brood density is too high, there will be more harmful gases in the house, and it will produce worms; the brood density is too small, the brooding area and equipment are not fully utilized, resulting in waste. The average density for flat raising is 20 per square meter, and 40-50 per square meter for cage raising.

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.

Using broiler battery cages to raising chicken is very convenient because it reduces the burden on most farmers, but it also places higher demands on farmers. Chicken living in cages also need to be managed. Some people will have some related problems. Today we will discuss the problems that should be paid attention to when raising broiler chicken with automatic breeding equipment.

  1. Matters needing attention in temperature

(1) Place the thermometer reasonably

In standardized chicken house breeding, the length and width of the chicken house are relatively large, and the temperature in the east, west, or north and south of the chicken house is inconsistent. Attention should be paid to the reasonable placement of thermometers. One thermometer should be placed in the east, middle, and west of the poultry chicken cages. Get the average temperature in the chicken house.

(2) Measures that change with the seasons

Need to cool down in summer. Breeders can use wet curtains and fans to reduce the temperature in the chicken house. At the same time, you should pay attention to the opening time of the wet curtain, to avoid the temperature in the chicken house is too low or the temperature in the chicken house is inconsistent, causing chickens to catch a cold.

 Temperature control in autumn. Because of the large temperature difference between day and night in autumn, the temperature in the chicken house should be adjusted to avoid the phenomenon of high and low temperature.

 In winter, heat preservation can be used to increase the temperature in the chicken house through heating or a blower.

  1. Pay attention to the problem of density

Pay attention to the density of broilers in cages. Actually, pay attention to the different feed intake of each cage chicken, adjust the number of chickens in each cage and achieve even feed intake.

  1. Matters needing attention in immunization

Raising broiler chicken in battery cages usually adopt drinking water immunization methods during immunization. When immunizing, attention should be paid to the vaccine dosage and drinking time. The drinking time should not be too long. Too long can easily reduce the efficiency of vaccine immunity.
