Technical methods for raising chickens in winter and spring

In winter and spring, the weather is changeable, the temperature is low, the rain and snow are high, the temperature difference between day and night and inside and outside is large, the chicken disease is many, the long speed is slow, the feeding period is long, the cost is high, and the survival rate is low. After many years of clinical visits and on-site observations, the author believes that raising chickens in winter and spring is the most difficult season of the year. To achieve an ideal feeding effect, the following issues should be noted: 1. Appropriate temperature and temperature are necessary to maintain chicken body growth. Preparation conditions. Maintaining the proper ambient temperature is the key to success in raising chickens. The ideal temperature for chickens is 32-28 °C for brooding and 20-25 °C for the rearing period, which is relatively constant, but it is difficult to meet this requirement in winter and spring. Therefore, we should strengthen the incubation period of brooding, maintain a suitable temperature, prevent the intrusion of thief winds and drafts. A group of chickens are evenly distributed, and the normal diet, quietness, and freedom of movement are the ideal temperatures. 2. Reasonable density and reasonable rearing density is a measure to increase the utilization rate of the site. It is also an effective means to use the chicken body to dissipate heat, increase the temperature inside the house, and reduce the cost of the chicken farm. Due to the low temperature in the winter and spring, the general stocking density is comparable to other seasons. Increase 10-15%. 3. Correctly deal with the relationship between heat preservation and ventilation. In this quarter, due to the increase of breeding density, the heat insulation of the chicken house is often neglected and the ventilation and ventilation are often neglected. Therefore, air pollution in the house can be easily caused and a large number of pathogens can be produced. Chickens inhale harmful gases such as C02 and ammonia for a long time and grow in the environment where bacteria grow. They often have high E. coli disease, chronic respiratory diseases, infectious bronchitis, laryngitis, and CO2 poisoning, leading to a decrease in survival rate. The correct method should be ventilated every 2~3 hours for 10~15 minutes. Especially for the brooding stage with plastic film insulation, it is better to open several skylights at the top of the shed to achieve the purpose of maintaining warmth and discharging air. People enter the shed without bad odor, and the water droplets on the plastic film around the shed are the ideal environment for sticking. 4. Feed quality The climate in this season is poor, and chicken resistance is relatively weak, so it is very important to improve feed quality. The protein content in the feed of the chicks should be increased by 3% to 5%. The energy in the feed during the rearing period should be appropriately increased, and the amount fed should be increased appropriately to resist the consumption of wind and cold. The rearing of the chickens was promoted for late release, and after 10 o'clock, the materials were put in and the water was cast in the evening to achieve the effect of both saving materials and fast fattening. 5. Strengthen the epidemic prevention work in the winter and spring seasons, especially the three yellow chickens that are stocked have long slow speeds, long feeding periods and high risks. It is necessary to strengthen strict and scientific prevention measures. In addition to routine immunization, chickens should be vaccinated against Newcastle disease around the age of 60 days in addition to routine immunizations. At the same time, special emphasis should be placed on immunization of chickens and bird flu. 6. Strengthen the concept of site disinfection Farmers only pay attention to the treatment of sterility disinfection. Due to the special conditions in winter, the resistance of the chicken body is poor and the intestinal flora is easily misaligned. Strengthening site disinfection and improving external environmental conditions are very beneficial to the chicken body. Especially during the brooding period, the chickens housed in the house are regularly cleaned, regularly disinfected, frequently replaced with litter, and the barrel water dispenser is sterilized every other day to prevent outsiders from entering. This is especially necessary. 7, disease treatment Winter chicken disease more, but it is prominent E. coli disease, chronic respiratory disease, paternity, throat, bird flu and so on. In addition to regular feeding and management, the veterinarian should immediately consult a veterinarian for treatment immediately and take measures to reduce losses.

Tattoo Machines Power Supply , Tattoo Power Supply is provided to the electronic device in the power of the apparatus, also known as tattoo power supply, which provides the power required by all the components of the computer. The size of the tattoo Power, current and voltage stability, will directly affect the performance and service life of the computer. Many disk arrays and rack-mount system contains more than one tattoo power input, they should be deployed to different tattoo equipment power input connection on the independent circuit device with two or three tattoo power supply input, so that, under normal circumstances , as long as the failure of the circuit is no more than one, the system will be able to continue normal operation. Therefore, if all the hardware in the cluster have two or three tattoo power input is required at least three separate circuits, to ensure that there is no single point of failure in the cluster circuit design.
