1 Buy good breeds. At present, good breed strains that are favored by chicken farms and chicken farmers in China are well-known egg breeders such as Luoman, Hyland, Yisha and Jingbai. However, because of the different climatic conditions in different places, the environment is different, and chickens of different breeds perform differently in different regions. Therefore, in order to purchase good varieties, it is necessary to choose local breeders with large stocks and good performance in production. It is imperative to seek new differences. Failure to understand the suitability of varieties in the local area causes failure and loss. Secondly, there should be a selection of chickens that have a certain amount of feeding and management conditions. Must not be greedy and cheap, buy chicks that are not breeder-derived or hatched.
2 Implement scientific feeding. First, do a good job of brooding and cultivate quality and robust chicks. According to recent years, domestic and foreign dog studies have proved. The weight of chicks is directly proportional to the main performance indicators of the egg production period. Therefore, high temperature brooding must be used during the brooding period. That is, 1 to 2 days old at 33°C, 3 to 4 days old at 32°C, 5 to 7 days at 30°C, and 8 to 14 days at 28°C. Afterwards, descend 3°C every week until 21°C. Secondly. To provide high-quality full-priced feeds and ensure light hours, 24 hours for 1 to 2 days, 22 hours for 3 to 4 days, 20 hours for 5 to 7 days, 18 hours for 8 to 10 days, 11 to 14 days of age. 16 Hours, 15 to 21 days old 15 hours, after 21 days, gradually keep 8 to 12 hours. At the same time, pay attention to ventilation. At 8 to 9 days old, we cut off. According to the epidemic prevention program for immunization and medication prevention. Second, during the growing period, we must focus on weight control and improve the evenness of the flock. In order to enter the rearing period, it is necessary to control the weight within the scope of the feeding standards and increase the evenness of the flock to more than 85%. Thirdly, it is necessary to provide a stable production environment during the production period and to prevent overfeeding of the chicken body. Chicken body fat. It will cause a lot of fat to invade the gonads. Affecting the development of follicles and the secretion of other gonads will result in decreased egg production. Excessive body fat can also cause fatty liver, causing the death of chickens to rise. For this reason, the laying period should also be periodically weighed to determine if the bird's weight is normal.
3 Give appropriate light. A good lighting program can promote egg production, increase egg weight, increase survival rate and economic efficiency of raising chickens. 1 to 2 days of age to give 24 hours of light, in order to facilitate feeding, and then gradually changed to constant light or natural light. After entering the breeding period, natural lighting is the main choice. Conditional light can be taken under constant light for 8 to 12 hours. Light stimulation was given for at least 13 hours at 18 weeks of age, followed by 15 to 30 minutes of light weekly or every 2 weeks until 17 hours. If the time of light is increased too quickly, it will cause offensive anal prolapse, licking and other undesirable phenomena. The light intensity of a laying hen house is generally controlled at 10-20 lux. During the laying period, the illumination time and intensity must not be reduced.
4 Reasonably prepare the diet. The feed formula is unreasonable and unscientific. First of all, it shows that the dietary nutrition is not fully priced, resulting in some nutrients that are too much and wasted, too little and under-nutrition, which affects the egg production rate. The second is to increase the cost of feed formulation, and local feed ingredients can not be deployed at any time according to local conditions. The third is that it cannot meet the needs of energy and various nutrients in different egg production seasons. For example, the metabolic energy of feed formulation in summer is lower than that of winter formula, otherwise it will not only waste the feed but also affect the chicken's metabolism and feed intake. Therefore, adopting a scientific diet formula is an important measure to increase feed remuneration.
5 Do a good job of disease prevention. Reducing dead chickens and eradicating the outbreak is the key to the success of chicken farming. It is necessary to scientifically control the epidemic prevention procedures of chicken disease. According to the age of different chickens, various vaccines were injected. At the same time, regular sterilizing of chicken coops and utensils was used to remove fecal matter in a timely manner. Rodents should be well-preserved around the house to prevent rats and sparrows from entering the house. In order to reduce the spread of the epidemic, personnel should be reduced as far as possible. Visits are denied and strangers are not allowed to enter the henhouse to ensure the health and safety of the chicken farm.
6 Pay attention to saving feed. The measures to reduce feed wastage: 1 The height, depth and length of the feed trough should be changed according to the different ages of the laying hens and the cage density. The amount of feed added can not exceed 1/3 of the depth of the tank, and less feeding should be added to reduce the food in the tank. The daily feeding rate is determined by the egg production rate. When the general egg production rate is 50% to 60%, the daily feeding amount of each chicken is about 95 to 100 grams, and the daily feeding rate is 60% to 70% when the egg production rate is 60% to 70%. 105 to 110 grams, when the egg production rate is 70%, the daily feeding amount of the chicken is 115 to 120 grams. When the egg production rate reaches 80% or more, the feed can no longer be limited, allowing the chicken to feed freely. 2 cut off. Since chickens have the habit of eating food, they should be chopped up at 7 to 9 days of age. By the age of 15 weeks, repairs will be required for people with severe disabilities. 3 Timely elimination of chickens that do not produce laying hens or poor laying performance. When the nursery is completed and transferred to the egg-laying house, a phase-out should be carried out. All stunted, too small, too fat, sick, or lack of energy should be eliminated. During the egg production process, swaddling chickens, diseased chickens, disabled chickens and discontinued chickens should be eliminated at any time. After entering the stage of laying eggs, the main discontinuation chickens are eliminated, and the hens with crowns, pale faces, or crowns should be eliminated immediately. Fatty, overly-lean chickens should also be eliminated immediately.
The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
