Grass chickens are also called local breeder chickens. The adaptability of grassy chickens is relatively strong, and feeding is relatively easy. However, at present, the farmers who raise the grass chickens have not yet formed a certain scale of breeding, and it is difficult to form economies of scale. The following points will be introduced as follows: 1. The rearing of grass chicks 1. Drink water and eat food in time. After the chicks are allowed to enter, they can drink water in 1 to 2 hours. At the beginning of drinking, 5% glucose and electrolytes can be added to the water to strengthen the body of the chicken, relieve stress, and facilitate the discharge of meconium. The water temperature is generally close to the shepherd's temperature (16~20°C). The chicks usually start eating 24 hours after hatching. At the beginning, they can feed broken rice. After 3 days of age, they feed the full price pellets. 1. Control the microclimate in the chicken house. The temperature control in the house is most important during the brooding period. The specific requirements are: 0 to 1 week old for 33 to 31°C; 2 to 3 weeks old for 30 to 25°C; 4 weeks old After 25 ~ 20 °C. The relative humidity in the house is preferably 55% to 65%. In the first week after hatching, the chicks need 20 to 23 hours of light each day; after the second week, the daily light can be reduced to 13 hours, and natural light can be gradually adopted afterwards. The general bulb is 2 meters away from the ground and 1.5 to 2 watts per square meter. 3. The suitable density for stocking should be appropriate. The appropriate density for stocking per square meter: 40 to 50 on day 10, 40 on 20th, 30 on day 30, 15 on day 60, 10 on day 90, and day 120 on day 120 8 only. Second, adolescent rearing grass chickens refers to 60 to 130 days of age. Young chickens are bred in males and males. This eases management and reduces feed consumption. The specific requirements are as follows: Small cock feeding. The small rooster is generally 100 to 120 days old and its weight can reach 0.8 to 1.2 kg, and can be listed. In order to make the small cocks meet the requirements of commercial weight on time, they are required to feed the full-price compound feed on the rearing and use high-energy, high-protein feeds to increase the feed intake. Appropriate grazing, and qualified farmers, can be grazing, so that the small rooster can eat some live food and green feed, and full of activities, so that the chicken to achieve delicious, delicate requirements. 2. Hens are raised during the adolescent period. Take restrictions on feeding, limit the nutrient levels in their diets, and properly reduce the ratio of protein and energy in the diet. In terms of management, the group should be transferred in due course. By the age of 120 days, young chickens should be transferred to laying hen houses for breeding. If the group is switched to another group at the time of opening, stress response is likely to occur, which will affect the chicken's egg production rate. Transit should be done in the evening and try to keep the chickens quiet. Third, the feeding and management of grass chicken laying period 1. Create and provide a suitable living environment. The temperature in the house should be maintained at 13 to 24°C; the daily illumination time is 14 to 16 hours, and the light intensity is about 2.5 watts per square meter. At the same time, the house should be kept quiet. 2. Formulate or select scientific feed formulations. Should be based on changes in chicken egg production, timely changes in feed formulations to meet the nutritional needs of chickens during the production period. 3. To regularly feed sand. Every afternoon, sand can be added to the feed for the birds to feed freely to enhance the chicken's digestive function. Fourth, the requirements of the rations When the grass chicken is in the brooding period, it is best to use the full-scale pellets for the early chicken. 2. During the adolescent period, the recommended cockerel feed formula was: corn 60%, soybean cake 20%, fishmeal 3%, bran 10%, shell powder 6.5%, multi-dimensional, trace elements 0.3%, table salt 0.2%. The hen recipe is: corn 52%, bean cake 10%, fish meal 1%, bran 15%, bran 14.5%, shell powder 7%, multi-dimensional, trace elements 0.3%, salt 0.2%. 3. During the production period, the feed formulation was: corn 58%, soybean cake 20%, fishmeal 4%, bran 10%, bone meal shell powder 7.5%, multidimensional, trace element 0.3%, salt 0.2%. The feed formulation should be adjusted according to the egg production of the chicken. V. Epidemic prevention and treatment Malrick subcutaneous injection at the age of 1 day, 10 to 12 days old small triple (bursae, Newcastle disease, transmission) oil intramuscular injection. Add some anticoccidial drugs to feeds 20-40 days old, the same coccidiosis drugs should not be used for a long time, 70 days old I line seedlings are injected intramuscularly and deworming at the same time, 130 days old, Newcastle disease oil emulsion intramuscularly, and again Deworming, usually once every two weeks with 1 antibiotic drugs, 10 days once inside and outside the chicken house can be disinfected.
Sorfa syringe filters are disposable laboratory consumables for filtration of aqueous solutions in four types of membranes: PES, MCE, PVDF, PTEFand NYLON. Accordingly, four color housings mate with these membranes for easy identification. For pore diameter of membrane, two sizes are available of 0.22 um and 0.45 um. Housing diameter also is in two sizes of 15 mm and 30 mm.
Each Syringe Filter consists of a circular ring shell, a luer-lock connection with a piece of circular membrane inside. The net structure on luer lock connector is diversion groove which guide aqueous solutions to fill connector during the filtration process. This feature takes full advantage of membrane area for filtration of aqueous solutions. All Sorfa syringe filters are packaged in plastic boxes with sterilization, RNase-free, DNase-free and Non-pyrogenic.
