Winter shed breeding broiler technology
Feeding broilers in plastic greenhouses in winter can make broilers grow short, flat, and fast without destroying cultivated land. The accumulation of fermented chicken manure and litter can be used in vegetable production. It has less environmental pollution and creates a better economy. benefit. Reconstruction of the Greenhouse 1. According to the east-west direction of the greenhouse, the south face of the slope will be replaced by the horizontally placed cement board in the north wall. The empty part shall be used for ventilation, and the remaining cement board shall be used as spare. 2. Set up the foot foot membrane to be used for ventilation. Set a standard to meet the moisture and ventilation of chickens in different stages of the greenhouse. 3. The bamboo raft is connected northwards along the north-south steel tendons to make it substantially flush with the north wall. The top is covered with plastic film and straw curtains, and a part of the northern side of the straw curtain should be hung down, and the ventilation openings should be properly blocked to protect the wind and blow the chicken body. In the reconstructed sheds, winter and spring seasons must be prevented from falling into the mold after the rain enters the rain. When the wind is prevented, the rain-proof membranes and straw curtains are prevented from being blown by the wind, and the birds in the shed are alerted. Preparation before brooding 1. First level and compact the ground. Ground level raising can be directly paved, and at the foot of the shed to prevent chicken escape. On-line breeding will require pillar nets. The height of the net should be taken into consideration when the excrement of chicken manure is convenient. It is generally 1 to 1.3 meters in width and 2-3 meters in width. The two rows of grids continue vertically and remain in the middle as walkways. 2. Check the installation of lighting and heating equipment, put the thermometer and hygrometer and correct it. Clean and disinfect all chicken utensils, dry them and put them in the greenhouse. 3. Disinfection. Frequent use of formalin and potassium permanganate fumigation, calculated as a unit of 15ml formalin + 7.5g potassium permanganate per cubic meter, can be used for 1-2 units in the initial culture shed, and it is necessary to raise the shed. Use 2-3 units, when fumigation should be sealed vents, and maintain a certain humidity, difficult to disinfect the parts to be sprayed with lime water or other disinfectant water, and firmly leave no dead ends. 4. Prepare common drugs, vaccines and feeds. The management of brooding uses a plastic film to separate a small area in the shed from the floor or a shelf for brooding, and gradually expands the brooding area in accordance with the size of the chicks. 24 hours before hatching, adjust the temperature and humidity in the shed so that the temperature in the broiler area reaches 35°C and the humidity reaches 65%-70%. The initial raising of greenhouses should be warmed up 48 hours in advance and the ground steam inside the shed should be excluded. 1. Temperature. During the growing period, chickens have different temperature requirements, but like other environmental chickens, they are basically 1-3 days old 35°C, 1 week old 35°C-32°C, 1-2 weeks old 32°C-29°C, 2 - 3 weeks old 29 °C - 27 °C, 3-4 weeks old 27 °C - 24 °C, 4 weeks later 21 °C -18 °C. It is worth noting that the decrease in temperature is a slow process, and its adjustment is based on the comfort of chickens. The temperature in the shed should be basically stable every day. There should be a large temperature difference between day and night in early spring and winter. To warm the general use of the ground furnace, which must be prepared before the hatching, coal stoves can also be used to warm, but to prevent gas poisoning. 2. Light. After 48 hours of continuous light, the intensity is about 25 watts per 10 square meters of light, followed by 23 hours of light, 21 days of age, gradually changed to 16 hours of light, 8 hours of dark, according to different seasons and time Turn on the lights in the evening and turn off the lights the next morning. The installation of the bulbs can be along the shed, one lamp holder every 5-8 meters, according to the production needs to install different power and color bulbs. 3. Drinking water feeding. Unless the need for immunity, generally should continue to water, chickens into the young, first give warm water, add 5% brown sugar and electrolytic multidimensional. Two to four hours after drinking, sprinkle the broiler health supplement on the tray. Feed 6 times a day in the first week. It is advisable to eat basically every 25-30 minutes in the dish. In the second week, feed troughs or drums were used and the feed was given 4-5 times a day. After the third week, they were fed 3 times a day to ensure that the material buckets were continuously fed but had less material. Every day, drinkers should be cleaned once in the morning and at night. The buckets should be kept clean, and chickens should be gradually replaced at different times. 4. Ventilation. Ventilation can meet the oxygen demand of broilers and the discharge of harmful gases, but the premise of ventilation is ventilation, and at the same time, it is necessary to prevent thieves from invading and blowing the chicken body. 5. Humidity. The humidity in the greenhouse should not be too large. It is better to use 65%-70% on 0-21 days and change it to 60%-65%. 6. Environmental health. It is best to prevent outsiders from visiting the shed. Timely elimination of feces, keeping chicken utensils clean and the breeder's own cleanliness, to reduce the number of chicken disinfection, so as to reduce stress. Can be isolated in a corner of the shed, isolated feeding for diseased chickens, dead chicken sealed with a plastic bag out of the greenhouse, fixed-point anatomical diagnosis and away from the shed to destroy. 7. Vaccination. The vaccination program and time should be based on the specific circumstances of each place. The following is for reference only. At 7 days old, Newcastle Disease II or IV seedlings were inoculated (one drop of each eye drop). 14 days of inoculation of attenuated virus vaccine (drinking water) of infectious Bursa. 28 days of vaccination with Newcastle disease II or IV seedlings (drinking water). Vaccination is a stress on chickens. Therefore, during the epidemic, the brooding temperature should be appropriately increased, and anti-stress drugs or multidimensional drugs should be added to drinking water for two days before and after vaccination. The vaccine dilution water is preferably cold boiled water, in which an appropriate amount of skim milk powder is added to prolong the effective period of the vaccine. Drinking water should be stopped 2-4 hours before the immunization, and increase the number of drinking fountains when drinking water to ensure that chickens can drink water and drink water within 2-3 hours. Eye drops vaccinated to achieve vaccine absorption really effective.
Pine nuts (also called pignoli) are the edible seeds of pines (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting; in other pines the seeds are also edible, but are too small to be of notable value as human food. Our Chinese pine nuts grow in Heilongjiang and Jilin province of China. The mainly varieties are pure red pine nut kernel and cedar pine nut kernel. Pine nuts have been eaten in USA, Europe, Asia and many other countries. They are frequently added to meat, fish, salads and vegetable dishes or baked into bread.
