What are the techniques and automated equipment for broiler chicken greenhouse farming?

With the development level of modern people, everyone's clothing, food, housing and transportation are rising day by day. Now the number and scale of broiler chicken farming are rising at an astonishing speed, and everyone is constantly learning. So some people will ask what broiler chicken farming techniques should be like, and what equipment there is for broiler chicken farming. Next, let's take a look together with the editor.

Greenhouse broiler chicken farming techniques

1. Appropriately modify the greenhouse

The standard for greenhouse modification is that the modified greenhouse can not only meet the needs of ventilation, heat preservation and humidity control for broiler chicken production, but also facilitate daily manure removal, epidemic prevention, feeding and watering and other production management work during broiler chicken production.

1. According to the east-west orientation of the greenhouse, with the slope facing south, change all the originally vertically placed cement boards on the north wall to horizontal placement, leave the empty part for ventilation, and keep the remaining cement boards for later use.

2. Appropriately lift the film at the foot of the slope for ventilation. The lifting standard is to meet the needs of moisture retention and ventilation for the chickens in the greenhouse at different periods.

3. Along the steel bar framework running north-south, connect bamboo poles toward the north so that it is basically flush with the north wall. Lay plastic film and straw curtains on it. The north end of the straw curtain should hang down a part to appropriately block the ventilation opening, playing a role in heat preservation and preventing wind from blowing directly on the chickens. For a well-rebuilt greenhouse, in summer straw curtains and rainproof film should be laid on the greenhouse, basically forming a shade shed to prevent heat and lower temperature and to protect against rain. In other seasons, the straw curtains and rainproof film should also not be removed, but in winter and spring it is necessary to prevent the straw curtains from rotting after rain and to prevent the rainproof film and straw curtains from being blown up by wind, startling the chickens in the greenhouse. The method is to fix the rainproof film with film-pressing lines.

2. Preparation before brooding

1. Level the ground. First level and compact the ground. For floor rearing, bedding material can be laid directly, and fences should be set up at the foot of the greenhouse to prevent chickens from escaping. For rearing on nets, columns should be set up to support nets. The height of the net should take convenience of manure removal into consideration, generally 1-1.3 m, with a width of about 2-3 m. Two rows of net frames extend longitudinally, with an aisle left in the middle.

2. Prepare the tools. Check and install lighting and heating equipment, place thermometers and hygrometers, clean and disinfect all chicken-raising tools, and put them into the greenhouse after drying.

3. Do a good job of disinfection. Formalin + potassium permanganate fumigation is often used. Calculate at 15 ml formalin + 7.5 g potassium permanganate per cubic meter as one unit. For a newly used greenhouse, 1-2 units can be used, while for a greenhouse that has been used for farming, 2-3 units should be used. During fumigation, seal the ventilation openings and maintain a certain humidity. For parts that are not easy to disinfect, spray with limewater or other disinfectant water, and resolutely leave no dead corners.

4. Prepare commonly used medicines, vaccines and feed. The main task of the brooding management stage is to increase the survival rate and weight gain of chicks. Use plastic film to horizontally partition off a small area of the greenhouse floor or net frame for brooding. According to the size of the chicks, gradually expand the brooding area longitudinally.

What automated equipment is there for broiler chicken farming

Automated chicken-raising equipment is mainly composed of a cage rearing system, an automated egg collection system, an automated manure cleaning system, automated feeding equipment, an automated lighting system, and environmental control system devices. The equipment is designed with automated control, and the operation method is relatively simple. It is suitable for intensive raising of brooding chickens, broiler chickens and laying hens of different scales. Now many chicken farmers are gradually feeling that traditional chicken-raising equipment cannot meet their needs, and are gradually moving from traditional manual farming equipment to automated farming. The farming industry is developing toward intensification, planning and standardization.

Notes on raising broiler chickens

1. Temperature. Chickens at different growth stages have different temperature requirements, but as with chickens raised in other environments, it is basically: 35°C at 1-3 days of age, 35-32°C at 1 week of age, 32-29°C at 1-2 weeks of age, 29-27°C at 2-3 weeks of age, 27-24°C at 3-4 weeks of age, and 21-18°C after 4 weeks of age. It is worth noting that the decrease in temperature is a slow process, and its adjustment is based on the standard that the flock feels comfortable during growth. The temperature in the greenhouse should be basically stable every day. In early spring and winter, the temperature difference between day and night is large, so the lifting and covering of the straw curtains on the roof eaves and at the foot of the greenhouse should be done well. Heating is generally provided by a ground stove, which should be prepared before the chicks arrive. A coal stove can also be used for heating, but gas poisoning must be prevented.

2. Humidity. The humidity in the greenhouse should not be too high. From 0-21 days of age, 65%-70% is better, and afterward change to 60%-65%.

3. Lighting. After the chicks arrive, start with 48 hours of continuous lighting at an intensity of about 25 watts per 10 square meters. Afterward use 23 hours of lighting. After 21 days of age, gradually change to 16 hours of lighting and 8 hours of darkness. According to different seasons and times, turn on the lights in the evening and turn them off the next morning. For bulb installation, it can follow the east-west orientation of the greenhouse, with one lamp holder every 5-8 m, and bulbs of different power and colors can be installed according to production needs.

4. Water and feed. Unless immunization requires it, water should generally not be cut off. After the chicks arrive, first give warm boiled water with 5% brown sugar and electrolytic multivitamins added. 2-4 hours after drinking water, scatter broiler chicken health feed on the feed trays. In the 1st week, feed 6 times a day, each time preferably with the feed in the tray basically eaten within 25-30 minutes. In the 2nd week, switch to feed troughs or feed buckets, feeding 4-5 times a day. After the 3rd week, feed 3 times a day, ensuring that the feed buckets are not empty but with relatively little stale feed. Because of pecking, feed is often pecked out of the feed buckets by the chickens, causing relatively large feed waste. A better method is to choose larger feed trays, place the feed buckets into the feed trays, and let the feed thrown out of the buckets by the chickens fall into the feed trays. Note that the drinkers should be cleaned once in the morning and once in the evening every day, the feed buckets should be kept clean, and chicken feed for different periods should be gradually changed in a timely manner.

5. Ventilation. Ventilation can meet the oxygen needs of broiler chickens and discharge harmful gases, but ventilation should be premised on heat preservation, and at the same time prevent drafts from intruding and wind from blowing directly on the chickens. In summer high temperatures, ventilation is especially important. The openings of the straw curtains and greenhouse film at the foot and ridge of the greenhouse can be enlarged somewhat. For chicken coma caused by high temperature and reduced feed intake, a small soda solution can be used to relieve it, or cold water can be used to lower the temperature.

6. Hygiene. It is best to prevent outsiders from visiting the greenhouse, especially other farmers, feed and veterinary drug salespeople, and chicken dealers. Remove manure in time, keep chicken-raising tools clean and the raisers themselves clean and hygienic, so as to reduce the number of chicken disinfection times and thereby reduce stress. Raisers should preferably change shoes and clothes when entering and leaving the greenhouse. A corner in the greenhouse can be isolated for raising sick chickens separately. Dead chickens should be sealed in plastic bags and taken out of the greenhouse, dissected at a fixed point for diagnosis, and destroyed far away from the greenhouse.

7. Immunization. Vaccination items and timing should be determined according to specific local conditions. The following is for reference only. At 7 days of age, vaccinate with Newcastle disease strain II or strain IV vaccine (1 drop each by eye drop and nasal drop). At 14 days of age, vaccinate with infectious bursal disease attenuated vaccine (drinking water). At 28 days of age, vaccinate with Newcastle disease strain II or strain IV vaccine (drinking water). Vaccination is a stress for chickens, so during the epidemic prevention period, the brooding temperature should be appropriately increased, and anti-stress medicine or multivitamins should be added to the drinking water two days before and after vaccination. The water used to dilute the vaccine is best cooled boiled water, with an appropriate amount of skimmed milk powder added to prolong the effective time of the vaccine. 2-4 hours before drinking water immunization, water should be appropriately withheld, and the number of drinkers should be increased during drinking to ensure that all chicks can drink water and finish drinking within 2-3 hours. Eye drop and nasal drop vaccination should ensure that the vaccine is truly effectively absorbed.

What are the profits and costs of greenhouse broiler chicken farming

1. Rough calculation and analysis of broiler chicken raising costs and profits

Calculate based on raising 10,000 broiler chickens per batch at each farm. Construction investment:

1. Raising 8-9 chickens per square meter requires 1200 square meters of usable greenhouse area.

2. Each greenhouse is about 250 square meters, requiring 4 greenhouses, each 30 m long and 8.5 m wide.

3. The total land area is about 2 times the usable greenhouse area, because there needs to be appropriate spacing between greenhouses, so the total land area is about 2400 square meters (3.6 mu).

4. Rearing on nets: level the ground, pull steel wires longitudinally at 0.7 m above the ground with 6 cm spacing, leave an aisle 1.1-1.2 m wide in the middle, and lay special plastic netting on top. Use 2 m as one compartment. Build pillars around the walls with cement blocks or bricks, leave doors and windows in the middle. The roof consists, from inside to outside, of one layer of plastic film, one layer of straw curtain, one layer of plastic film, and small red tiles hung on the outside, four layers in total. The construction cost is about 80 yuan per square meter, so the construction cost of each greenhouse is about 20,000 yuan, and the total construction cost of 4 greenhouses is about 80,000 yuan.

2. Raising costs

1. The annual average purchase price of chicks is about 3.5 yuan each.

2. Based on 42 days of raising, each chicken needs about 5 kg of feed, the feed-to-weight ratio is 1.85:1, and the total feed cost is about 11.4 yuan.

3. The whole-process medicine cost per chicken is 0.7 yuan, water and electricity cost 0.2 yuan, coal cost 0.1 yuan, labor cost 0.4 yuan, about 1.4 yuan.

4. The total cost above is about 16.3 yuan per chicken, and the cost for 10,000 broiler chickens is 163,000 yuan.

3. Sales revenue

Based on broiler chickens growing to 42 days with a body weight of 2.7 kg, and an annual average of 8.0 yuan per kg of live chicken, the sales revenue is 21.6 yuan per chicken, and the sales revenue for 10,000 broiler chickens is 216,000 yuan.

4. Farming profit

1. The raising cost per broiler chicken is 16.3 yuan, the sales revenue is 21.6 yuan, and the profit is 5.3 yuan. The profit for 10,000 meat ducks is 53,000 yuan.

2. Recovering the construction cost requires raising 1.5 batches of broiler chickens. Based on raising 5-7 batches per year, averaging 6 batches, the construction investment can be recovered in the same year, with a profit of 238,000 yuan.

According to the laws of feed conversion in modern society, and comprehensively considering factors such as current market conditions and feed prices, now reasonably arrange the production and marketing of broiler chickens to maximize economic benefits. Based on the editor's answers above, I believe everyone now knows some broiler chicken farming techniques and some equipment.
