The cultivation of young prostitutes is a very meticulous and important task in the breeding of cockroaches. The quality of the bred chicks directly affects the growth and economic benefits of crickets. Therefore, how to increase the survival rate of the young chicks has become the primary problem for each breeder. According to the practice of brooding for many years, the author summarized some of the experiences and introduced them as follows. Preparation before brooding 1. Determining the brooding method Before purchasing the chicks, you must determine the brooding method (ie cage or flat raising), and then arrange the brooding house according to the planned number of rearing. 2. Preparation of premises and equipment The brooding house requires good insulation properties, and it can be ventilated as required. It should not leak rain, and the ground should be dry to prevent rat. Check whether the premises are leaking, whether the doors and windows are tight, if there are mouse holes around, doors and windows must be added to the barbed wire to prevent the pupae from flying out of the house and prepare all the feeding equipment. 3. Sites and utensils shall be thoroughly cleaned 3-5 days before hatchlings. The poultry house floor and all feeding utensils (drinkers, feed barrels, etc.) must be thoroughly cleaned. The disinfectant is 0.1% of benzalkonium, 1:2000 of 100 poison and 2 % sodium hydroxide. Then, after the floor is dry, put a pad or cloth and put the brooding utensils into the house to seal the doors and windows. According to the size of the poultry house, 7 grams of potassium permanganate per cubic meter, 14 milliliters of formalin fumigation, closed to 24 hours before feeding, open doors and windows, remove odors, gas and then close the doors and windows back. Create a good environment 1, temperature and temperature is an important factor in the success of brooding, to provide a suitable temperature for the chicks, can effectively improve the survival rate, accelerate growth and development, improper high and low temperature is a stress factor that causes disease, all ages The temperature requirements are shown in the table below. The young chicks have small body size, weak digestive function, little food intake, and little heat production, but their body surface area is large and their heat dissipation is high, and they are easily affected by external influences. Therefore, it should be frequent inspections to observe the dynamics of the herd group and determine whether the temperature is appropriate. If the temperature is appropriate, the chicks lively and disperse in the brooders, and their appetite is exuberant. When the temperature is too high, the chicks are far away from the heat source, the feed intake is reduced, the amount of drinking water is increased, the mouth is open for breathing, and the feces are thin; when the temperature is too low, the young The squeezing, necking, loss of appetite, and accumulation under heat sources. 2. Humidity The broiler environment humidity is very important for the growth of youngsters. If the humidity is too high, the body surface is difficult to dissipate heat, the appetite is weak and susceptible to disease; the humidity is too low. The feathers of the young beak are dry, tend to have armpit hairs, licking and anal fistulas. . The suitable humidity is 60%-70% within 1 week of age and 55%-60% after one week. 3. Ventilation and ventilation The young chicks grow fast and their metabolism is strong. There should be enough fresh air in the house to make the chicks grow fast. Under the premise of ensuring a certain temperature, properly open doors and windows for ventilation, but do not let the chicks get cold. 4. Density of each day-old alfalfa is 80-100 per square meter from 1 to 10 days of age, 50-60 per square meter from 10 days to 4 weeks, and 30 per square meter from 4 to 13 weeks of age. -35 only. 5, light from the shell within one week of the chicks can be implemented full-time lighting, 20 hours a week after the light, with the increase of the age and reduce the lighting time, and the light should not be too strong, 2 watts per square meter, or prone to feathers , assholes, toes and other evil. Scientific feeding and management 1. Drinking water Before the chicks enter the chicks, prepare 0.1% oxytetracycline water to promote meconium excretion. In addition, putting stones in drinking fountains can prevent young chicks from immersing themselves in water and causing illnesses. On the other hand, they can induce chicks to drink water. The next day can use water-soluble multidimensional or compound vitamin B solution alternately to adjust the appetite of the chicks. 2, after the start of eating young ducks, open water, you can eat, the initial training can be sprinkled on the mat cloth, so that young chicks eat, 2-3 days after the progressive use of feed bucket instead, feed drums should be placed near the lights, Let the chicks see the feed. The 1-3 day old chicks can keep feeding for the whole day, and then feed them 3-4 times a day to increase the feeding ability of the chicks. 3, cutting off if the feeding and management of small density, can avoid the occurrence of earthworms, generally not cut. Because of the great stress on the skeleton. If the measures fail to meet the requirements and occur, they can be completed at the same time when they are 50 days old. Anti-immunity work 1. A disinfection tank shall be set up at the entrance and exit of the poultry house. Breeders entering the poultry house shall change clothes and shoes, and outsiders shall be strictly prohibited from entering the house. 2. Adhere to the all-in, all-out system. After the feeding and transfer of the chicks, they must be strictly cleaned and disinfected before they can enter young chicks. 3, wash drinking fountains, frequently changing litter or cloth, is conducive to disease prevention. In the practice of brooding for many years, according to the characteristics of the disease at different stages of the disease, a reasonable set of preventive drug and immunization programs can be developed.
