Breeding broiler chickens need to pay attention to what?

In recent years, broiler chicken flock morbidity rate is high, not easy to prevent and control, so that the cost of feeding increased, the benefits of decline, so that farmers in a dilemma, a dilemma.

How to raise broiler chickens, improve efficiency? Now I raise broiler lessons summarized below for broiler farmers reference.

First, efforts to create a perfect standardized rearing facilities. Let the chicken on the net frame, clean and hygienic, in order to reduce the cost of medicine. The roof and walls of the chicken coop should be well insulated against heat to reduce heating costs.

The second is to select and raise new varieties of excellent broiler chickens with strong disease resistance.

Third, the feeders should be responsible. Each link (on the chicken, transportation, open water and food, heating and constant temperature, catching chickens, fire prevention) each step should be strictly required, meticulous, from the temperature change to ventilation, from feeding drugs to hygiene and epidemic prevention, from the chicken coop disinfection to disinfection of chickens, can not be lax, and strive to create an excellent growing environment, so as to prevent the problem before it occurs.

The fourth is to diligently observe the feces and the growth of the chickens. Problems in time to solve, found that the disease quickly and timely to find the cause of the disease, anatomical laboratory, the right medicine, do not delay, otherwise it will delay the treatment, increase the cost of medicine, increase the mortality rate.

Fifth, adhere to the "prevention-oriented, prevention and treatment, treating the symptoms, treating the root cause, treating both symptoms and root causes" policy.

Sixth, usually as much as possible to reserve a large number of garlic, garlic seedlings, ginger seedlings, chili pepper straw and other "three spicy", as well as artemisia, ai and other herbs. These materials will be dried and crushed to make additives. These additives are inexpensive, full-featured, disease prevention and health care, each batch of chickens regularly fed four courses (2 days a course) can significantly improve the resistance of the chicken body, prevention of enteritis, E. coli and viral diseases, coccidiosis. It has been reported that Guangwang County broiler company to implement the whole period of feeding herbal additives, the production of green broiler, favored by Japanese customers.

Seven is the rational use of high technology.

1, the application of micro-ecological preparations. There are reports: Qingdao Jiu Lian Group in the broiler rearing process, the extensive use of micro-ecological preparations to improve the growth environment of broilers, the output of the natural chicken, so that the Jiu Lian Group's products unimpeded exports to Japan, the Middle East and other countries.

Micro-ecological preparations are beneficial microbial flora developed by biotechnology, which can maintain the micro-ecological balance of the intestinal tract of livestock and poultry, prevent and control yellow-white dysentery and coccidiosis, and promote the growth of livestock and poultry. Weight gain significantly, improve feed conversion rate, enhance immunity and disease resistance, can reduce or replace the use of antibiotic drugs, the production of green broiler. Which contains the most microbial species for EM flora, mainly used for feed, drinking water disinfection.

First of all, mix EM into the full-price feed gradually at a ratio of 3-8%, and don't interrupt it from the last chicken to the pen.

Secondly, drink water and feed antibiotics alternately. 1-7 days old 300 times the proportion of drinking water, 8-14 days old 500 times the proportion of drinking water, 22 days old and 500 times the proportion of drinking water to the pen.

Again, 3 hours before entering chickens, use EM200 times liquid to spray disinfect the chicken house, utensils, work room, so that beneficial bacteria occupy the whole environment. In rearing, insist on every other day with 200 times the proportion of chickens with disinfection, including air, ground bedding spray disinfection. Not only can it eliminate odor, ammonia, inhibit germs, mold reproduction, but also eliminate dust floats, reduce the incidence of chicken respiratory disease.

2. Strong nano 863 bio-booster use. Strong nano 863 use without external energy, widely used in plants and animals in many stages of growth. Nano 863 will have a magical effect, because it contains nanomaterials, when the water, feed, seeds and its contact, it will be able to send them a steady stream of special bio-energy, so that its activity is greatly increased, activation of biological cells and tissues, to promote the growth of plants and animals to improve immunity, enhance resistance, scientists call it "energy block". The emergence of strong nano 863, for agriculture and fisheries of high quality, high yield, high efficiency, low consumption to avoid a new road, by the majority of farmers and friends welcome. Its correct use:

Treatment of drinking water, the strong nano 863 long-term immersion in the water storage container, the perforated surface facing up, each nano 863 maximum processing capacity of 150 kg, the first treatment needs more than 5 hours, and pay attention to the use of with the addition of recycling.

Handling feed: When dealing with bagged material, insert the strong nano 863 with the porous side down into the surface, tie the bag tightly, and then use it for feeding after 8 hours of treatment. When dealing with loose material, first lay a plastic film on the ground, and then 150 kilograms of material piled into a small pile, the nano 863 into the bottom of the material, processing 1 night can be fed. The longer the treatment time, the better the effect. Diluting drugs with water treated with Nano 863 can significantly improve the efficacy. Verified by authoritative organizations and many chicken farms test shows that: Nano 863 is a necessary appliance for chicken farmers.

Comprehensive the above, adhere to the prevention-oriented, both symptomatic and curative, timely and rapid restoration of chicken health, coupled with the application of high-tech, the experimental control proved that: can greatly improve the feed conversion rate, save feed, reduce production costs, disinfection and anti-odor, improve the environment, so that the chicken morbidity rate has been greatly reduced, 1 chicken to save nearly 1 yuan of money on medicines, feed saving 0.5 kg or so, weight gain of 200 grams, an increase of 1 yuan of money, comprehensive measures to do, the chicken is not a good idea. The comprehensive measures are done, and it is not a problem to increase the income of 1 chicken by 2 yuan. And the use of EM and nano 863, chicken meat quality is good, no drug residues, is green food.

Several good ways to raise good broiler chickens in winter

The purpose of broiler production is to obtain the maximum economic benefits and good quality products, but due to the fast growth of commercial broiler chickens, resulting in the broiler's ability to adapt to the environment and the decline in the resistance to disease, and at the same time susceptible to the quality of the feed and many other factors, resulting in a reduction in the feed remuneration for broiler chickens, the death of a high rate of amortization, which ultimately led to a reduction in economic benefits. This results in lower feed remuneration and high mortality rate, which ultimately leads to lower economic benefits. Therefore, in the winter rearing broiler, master the following broiler feeding management is very important.

1, the chicken coop building insulation performance should be good, timely ventilation

The winter climate is cold, and the temperature of the house needs to be with the outside temperature difference is huge, both to ventilate, but also to maintain the temperature of the house, which is the winter should be solved the main problem. Chicken coop requires good performance of cold-proof, to achieve the requirements of winter heat preservation. Strictly prevent the occurrence of chickens due to low temperature caused by piling up and squeezing to death.

At the same time in the ventilation, pay attention not to cause the temperature in the house suddenly high and low, to prevent excessive temperature difference caused by the stress reaction caused by disease, the vent to be higher than the back of the chicken above 1.5 meters is appropriate. When the temperature drops sharply, cold insulation work can not keep up, often easy to make broilers outside the wind cold, coughing, sneezing, trachea mouth sound, respiratory distress and other symptoms characterized by respiratory diseases. Therefore, breeders should grasp the changes in the climate, do a good job of cold insulation. Chicken coops should be well maintained to prevent thieving winds and penetrating winds from attacking the flocks. Broiler flocks raised on flat ground should be padded thickly, using the bedding to raise the indoor temperature. The bedding should be changed frequently, and windows should be opened at noon for ventilation. In general, ventilation starts at 6 days of age and increases with the increase in age, increasing the amount of ventilation so that the chickens have enough oxygen. Chickens into the house before 3 days, the house temperature control at 34.5 ℃ -35 ℃. Chickens into the house, warming 1 ℃ -2 ℃, the first week the temperature in the 35 ℃ -36 ℃ is good, this time the chicken state is good, the spirit of lively, uniform distribution, freedom of movement, diet is normal. At the same time, should pay attention to the chicken changes in time to adjust the temperature, if the chickens gather, "gibberish" trembling call, shrinking the head, etc., indicating that the temperature is too low, you should raise the temperature of the house; if there is open-mouthed gasping, frequent drinking, etc., indicating that the temperature is too high, you should reduce the temperature of the house. In 2 weeks of age down to 30 ℃ -32 ℃, in 3 weeks of age down to 26 ℃ -28 ℃, and then 1 week time down to a constant temperature of 23 ℃.

2, anti-ammonia accumulation

Winter climate is cold, can not be in order to give the chicken coop insulation and neglected ventilation, the chicken excretion of feces and wet bedding is not timely removal, resulting in the accumulation of ammonia in the coop, the concentration increases, resulting in ammonia poisoning of broiler chickens or triggering other diseases. Ammonia can strongly stimulate the respiratory mucosa and cornea of the chicken, usually cause the following hazards to broilers: chicken spirit, loss of appetite, oral fluid viscous, increased desire to drink, severe cases of respiratory distress, coughing, sniffling, tearing, cornea red, until death. Due to the accumulation of ammonia in the house, the relative lack of oxygen, coupled with the cold weather, the chicken's metabolic rate increases, for fast-growing broilers, it is easy to trigger ascites syndrome. In order to prevent the adverse effects of ammonia on broilers, it is recommended that chicken farms and chicken catch the following feeding management: laying bedding to have a certain thickness, generally more than 5 cm; operation to minimize the sprinkling of water, to prevent leakage of water from the sink, wet bedding; if the humidity in the chicken house is too large, it should be timely removal of fecal matter and wet bedding in the house. In addition, you can use ammonia-absorbing deodorizers to reduce the concentration of ammonia in the chicken house, commonly used ferrous sulfate, superphosphate, copper sulfate, slaked lime and so on.

3, reasonable feeding, to prevent the spread of disease

According to the different growth stages of broiler, according to the standard feeding rations. Due to the low temperature in winter, broiler heat consumption is greater, the preparation of rations can be appropriate to raise the standard of metabolic energy in the feed, and appropriate reduction in the proportion of protein in the feed, while special attention should be paid to the content of vitamins in the ration to meet their needs. The feed should be mixed and fed now to prevent freezing, and when possible, it can be fed with hot food and warm water. The original grain of the allocated feed must be free of mold and impurities to prevent the induction of respiratory diseases.

Do a good job of preventing viral and bacterial diseases, when the broiler body is weak, resistance to decline, the occurrence of some diseases can also be complicated by respiratory diseases. Therefore, in improving the body resistance at the same time, to do a good job in the prevention and treatment of related diseases. There are vaccine preventive inoculation should be strictly in accordance with the immunization program for preventive injection. Normally, we should often use some drugs to prevent diseases. Regularly disinfect the chicken coop, empty chicken coop is best to use formalin fumigation disinfection, feeding period is appropriate to use efficient non-toxic disinfectant spray disinfection. Regular disinfection with chickens, generally using spray disinfection and water disinfection with the implementation. After the occurrence of respiratory diseases in broiler chickens, we should find a veterinarian to confirm the diagnosis and prescribe the right medicine. Symptomatic treatment can be appropriate application of some asthma, cough medicine, can reduce the number of deaths due to respiratory difficulties. The principle of prevention and treatment should be taken as the main focus of prevention, treatment as a complementary comprehensive measures: the establishment of a strict health and epidemic prevention system, improve environmental hygiene, strict control of outsiders, vehicles into the production field, the development of a scientific and effective disinfection system; to strengthen the monitoring and purification of the breeder; drug prevention and treatment; immunization. Broiler rearing in winter must solve the contradiction between ventilation and heat preservation, maintain the air quality in the house, strengthen the hygiene management, and rationalize the use of medication, so that the morbidity rate will be greatly reduced to ensure the growth and production of broilers, so as to obtain the desired economic benefits.

4, strengthen feeding management

Before entering the chick, the chick house is strictly flushed, disinfected and fumigated. Thoroughly clean the utensils, clothes, hats, premises and so on. Due to the physiological characteristics of meat chicks needs, after entering the house, the first water after the opening of the food, especially long-distance transportation of chickens, can be timely to replenish the body of the lost water. For chickens that are not willing to move around, the measure of artificial bombardment should be used to force them to feed, but care should be taken to keep the action light and not to cause the phenomenon of death by extrusion. Light time should be shortened, should not be extended, do not arbitrarily change the location of the light source, time, intensity, etc., so that the house illumination uniformity.

The ground should be dry, the cement floor does not absorb water and is easy to humid, it is best to use the triple soil to play the ground, the ground is breathable, to keep dry and not anti-moisture.

Choose a good bedding, to use fresh, dry, soft, not moldy, absorbent bedding, preferably shavings. Use to be skillful, it is best to lay a good bedding, do not add sporadically, and should be turned often, so that it does not harden, do not drive the felt, do not slate, to maintain the fluffy.

Control of drinking water, meet the water needs, generally drinking water is 2-3 times the amount of food consumption, but not more water supply, because more water will exacerbate the dampness of the bedding, do not wash dishes in the house, do not store water in the house, to prevent the bedding from absorbing water, and to prevent the running of the hose when using the hose.

Chicken diets do not overuse salt, to prevent drinking more water, resulting in high moisture content in chicken manure or dilution, wetting the bedding. In addition, the fat content of the feed should not be too high, otherwise it will make the feces sticky, falling on the bedding is easy to slate, chickens lying on the top of the easy to cause chest inflammation, cysts, dietary protein added to the right amount, too much is not easy to digest, such as feeding soybean cake is more than easy to dilute, wetting the bedding grass is harmful.

To solve the prominent problem of the formation of chest cysts, such as cage or online, can be in the bottom of the cage or the bottom of the net, plus a layer of soft rubber strips to prevent the chicken's chest in direct contact with the sharp and hard wire, to avoid causing chest cysts. Flat chickens can also be prevented from developing intestinal diseases by using soft and good bedding grass instead of hard bedding or crusty material.

Broiler flocks raised online are susceptible to non-infectious respiratory disease, especially in broilers around 25 days of age during the winter months. The pathogen of the disease is not bacteria or viruses, nor parasites, but the result of poor feeding management, generally from the first day, continuous or intermittent air dryness, too much dust, and in the case of poor ventilation, was inhaled by the flock, long-term accumulation and disease. Preventive measures are to increase ventilation under the premise of maintaining the temperature of the house to ensure that the oxygen content of the house is the basic conditions for chickens not to develop disease or less disease and to recover as soon as possible after the disease. To maintain a certain degree of humidity in the house, the first week humidity of about 20%, the second week to the pen humidity should be maintained at about 60%. 3 weeks of age or older broilers should be ventilation-based, the house temperature is not less than 21 ℃ can be. Minimize unnecessary stress factors, take all feasible means to let the chicken feed, in order to ensure the body's energy needs, enhance the ability of chickens to resist disease. In addition to the above measures, add the appropriate amount of antibacterial drugs and vitamins or baking soda in the drinking water and feed to enhance the chicken's ability to resist stress and alleviate the acidosis caused by poor respiration.

5, health management of chicken farms

First of all, chickens should be introduced from healthy breeding farms to prevent pathogens from being brought in by vertical transmission. Secondly, we should create a good feeding environment, including the big environment of the chicken farm and the small environment of the house. The big environment means that the site should be chosen far away from other chicken farms, with open terrain, convenient transportation and no noise and other external interference. The environment inside the house refers to good heat preservation and ventilation conditions, equipped with a separate storage room, disinfection pool, changing room, tool room and so on. Feeding utensils are strictly differentiated from disinfection utensils and disinfected regularly to prevent horizontal transmission of diseases, while regularly monitoring adjacent chicken farms and the region for the occurrence of disease outbreaks and taking preventive measures. Regularly monitor the health status of the chickens in the farm, and deal with the epidemic in time. Third, adhere to the principle of disinfection with chickens, eliminate rodent pests, strictly prevent the spread of disease by rodents, sick and dead chickens burned and disposed of, sick chickens and healthy chickens isolated.

In short, winter broiler feeding management is a comprehensive work, in addition to the above points, there are chickens, immunization, beak, feed quality, feeder management and other aspects of the impact of the factors, so only to master all aspects of the link to the key points of a comprehensive approach to consider, in order to improve the economic efficiency of winter broiler.

How to raise broilers in summer

In chicken production, environmental temperature is one of the important factors affecting the performance of broilers. Broiler to 28 days of age, the optimal production temperature is 21 ℃, and the summer coop temperature is often more than 30 ℃, broiler rearing is very unfavorable. Because of the difficulty of raising broilers in this season, so the summer is called the broiler rearing of the "adverse season", that is, not smooth season. The impact of high temperature on broilers is mainly manifested in the following four aspects: (1) a significant decline in food intake, growth rate slowdown; (2) faster respiratory rate, increased water intake. When the house temperature reaches 35 ℃, it can lead to the death of broiler heatstroke; (3) due to the reduced growth rate, the broiler feeding period is prolonged, and the nutritional requirements used to maintain its growth are increased, which will ultimately reduce the feed remuneration of broilers; (4) due to the increase in drinking water, the water in the chicken excreta is also increased, and the bedding material is moist. It is easy to cause the occurrence of coccidiosis.

It can be seen that the harm produced by high temperatures on broilers is more serious, and reasonable measures must be taken in the summer, while strengthening the feeding management, as effectively as possible, to reduce the negative impact of high temperatures on broilers, so that broiler production is maintained at a high level. Now on the summer high temperature during the technical points of good broiler chicken is introduced as follows, for reference.

1 Strengthen ventilation and heat dissipation, reduce the temperature of the house

The power of the exhaust fan can be increased, such as the use of multiple 9FJ 1.2 8 m3 / s fan, so that the flow of wind through the chicken body to increase the speed of wind, and in a timely manner to take away the heat produced by the chicken body to accelerate the discharge of heat in the house. Practice has proved that early in the morning before the opening of additional ventilation is the most obvious effect, not only can make the broiler feed for a long time, during the day to endure higher temperatures, but also conducive to reducing the maximum temperature value of the day in the chicken coop.

2 Installation of wet curtain cooling

Conditions can be installed wet curtain cooling device, there are comparative data show that the difference between the wet curtain cooling and the outside temperature of an average of 5.8 ℃, with no installation of the wet curtain house an average of 3.4 ℃. m

3 Let broilers drink cool drinking water

The temperature of the deep-well water is generally around 18 ℃, is a good broiler cool drink, can effectively reduce the stress caused by the heat. As the broiler water consumption increases at high temperatures, the fecal excretion is also large, which can take away more heat from the broiler body, so the conditions of the place can be used for self-flowing water tanks, continuous water supply from a small pump, to keep the drinking water at a low water temperature. If you use the traditional vacuum type drinker, to increase the number of water changes, add the drinker water should be just pumped out of the deep well water.

4 Thermal insulation and shade and roof sprinkling chicken

The roof is the largest part of the heat surface of the chicken coop, available straw or straw to do the roof. If the roof is made of other materials (such as asbestos tiles, cement boards), can be covered with straw curtains or plant vines for shade, can reduce the temperature of the chicken coop to a certain extent. In the roof with automatic sprinkler spraying cool water, more can achieve the effect of reducing the temperature of the house.

5 Cooler to strengthen the feeding

Broilers in the cooler will increase the amount of food, therefore, in the temperature drop, the weather is cooler should pay attention to timely feed, do not miss the feeding time, as far as possible to increase the amount of broiler feed.

6 Adjustment of feed formulation

When heat stress makes the broiler's feed intake is greatly affected, should be used in high-energy, high-protein diets, such as adding fat to the diet to increase the concentration of energy, which can make the broiler's resistance to heat stress increased. Another example is the addition of major amino acids (lysine, methionine) can reduce the body heat gain of broilers with heat stress and improve feed utilization.

7 appropriate to add vitamin C

General chicken will synthesize its own vitamin C to meet its growth needs, so the chicken does not lack of vitamin C. But in the heat stress, the chicken synthesize vitamin C ability will be greatly reduced, can not meet their own needs. Because vitamin C has a cooling effect, can alleviate the adverse effects of heat stress on the chicken metabolism, therefore, summer should be added to the broiler rations of vitamin C, can be added to 100 kg of feed ≥ 40% vitamin C powder 50g, or l00 kg of drinking water to add ≥ 40% vitamin C powder 25g.

8 Prevention and treatment of coccidioidomycosis chickens disease

The summer bedding moisture and high temperature are The humidity and high temperature of summer bedding are suitable conditions for the development of coccidia, which can easily lead to outbreaks of coccidiosis. Farmers should always add anti-coccidiosis drugs (e.g., coccidioidomycosis, coccidioidomycosis, coccidioidomycosis) to the feed on a rotating basis. When chickens have bloody diarrhea, anti-coccidiosis drugs should be used in combination with the hemostatic agent vitamin K3, which has a better therapeutic effect.
