Brooding technology

鹌鹑 Short for short, it is small in size, matures early, has a high egg production rate, has strong fertility and high feed conversion rate, and is easy to feed. The following is a brief discussion of brooding techniques for quail. 1. Preparation before brooding Prepare a brooding room with warm, sunny, well-ventilated, and dry ground before brooding. In the small-scale brooding of a family, it is generally possible to use a part of an ordinary vacant house, or to segregate part of it in a dormitories. If large-scale professional brooding is performed, special brooding rooms need to be built. Prior to brooding, the brooding room, brooders, feed pellets, and drinking fountains should be thoroughly disinfected, and 2% to 5% caustic soda water should be used on the ground for disinfection. The interior walls should be brushed with 5% to 10% lime milk. For the trough, drinking fountains, etc. can be used potassium permanganate solution cleaning and disinfection. The brooders must be warmed up and adjusted to the proper temperature one day before the brooding. The feeds, medicines used, and litters of the prostitutes should be prepared properly so as not to cut the material or drugs in the middle and cause passive work. After picking shells, they must be selected and timely eliminated weak, thin, disabled and other unqualified ones. Second, the brooding conditions 1. The temperature is appropriate temperature is the brooding period necessary regulations, because the newly hatched chicks thermoregulatory performance is poor, both afraid of cold and heat, the temperature is not appropriate, will reduce the survival rate. Within 3 to 5 days after the start of brooding, sack sheets must be laid on the floor of the brooding box. The sack sheets are both thick and soft, easy to keep warm, and must not be filled with plastic film. Because the chicks are liable to slip, they can be stung by pressing. After 3 to 5 days of brooding, the brooding ground may be covered with wood shavings; if it is kept in a brooding cage, sack sheets may be taken out to allow the feces to leak from the mesh hole to the underlying stool board. For young chicks within 1 week of hatching, the brooding temperature should be within the range of 35 to 37°C, and then decreased by 1°C every two days or by 2 to 3°C per week thereafter. The suitable temperatures for the young chicks at different ages are: 1~6, 7~12, 13-18 and 19-25 days of brooder temperatures are 35~37°C, 31~34°C, 26~30°C and 20~ 25 °C, but the actual application should also be flexible according to the outside temperature and the dynamics of the chicks. When the temperature is suitable, the chicks lively, have good appetite, moderate drinking water, light and neat feathers, and are evenly dispersed at rest, and do not play piles. They are relatively stable and do not often cry. They usually walk around the heat source. When the temperature is too high, the youngster shows mouth breathing, grabs water to drink, mouths open, has puffy feathers, and stays away from heat sources and concentrates on the edges of the brooders. When the temperature is too low, the chicks are crowded under a heat source, play piles, erect feathers, scream with closed eyes, and tremble, causing death. The incubation time of the chicks should be determined according to the specific circumstances. In general, the spring and autumn brooding insulation can be heated for 24 days or so, in the summer as long as the insulation is 4 to 5 days, and the winter insulation time is about 20 days to remove the temperature. It is necessary to constantly observe the newly deprived chicks and pay attention to the changes in the weather and temperature so that they can adapt gradually. Since the brooding temperature is appropriate for the success or failure of the brooding, in the event of a power outage in the case of brooding by electrothermal insulation, emergency measures must be taken to prevent the chicks from being cold. If the power outage time is short, you can temporarily store the chicks in a cardboard box covered with cotton and use the warm-keeping method. If the power-off time is too long (more than 12 hours) and the number of brooders is excessive, other heat sources should be used for remedy. When the young chicks encounter cold temperatures, they will crowd each other, play piles, get cold or be crushed to death. 2. Humidity In the first 5 to 6 days after the start of eating, the humidity is controlled at 65% to 70%, which is close to the humidity in the hatching machine. If the hatchling is in a dry brooding box after hatching, the youngster is not easily adapted to the physiological condition. It helps young prostitutes to digest and absorb the remaining yolk in the body. The method to increase relative humidity is generally to use an empty tin box and other utensils to fill the water, and then take a towel and hang it on the lid. The other end is immersed in water and the water can evaporate with the absorption of the towel, thereby increasing the inside of the box. Relative humidity. After 5 to 6 days, the relative humidity can be maintained at 50% to 60%. 3. Ventilation and ventilation The growth and development of young chicks need sufficient oxygen. To keep warm, excessively closed brooding boxes will hinder the circulation of air and cause oxygen shortage and carbon dioxide accumulation, thus affecting the growth and development of the chicks. Therefore, the brooding box ventilation holes should be opened frequently or covered with paper to allow air circulation. 4. After 1 to 7 days after the hatching of the chicks, the light was continuously irradiated for 24 hours, and gradually decreased until the light was irradiated for 14 to 15 hours per day. When not lighting, small lights should be turned on to facilitate eating and drinking. The color of light is best with red and white light, and generally use ordinary incandescent light bulbs. 5. Feeding density The stocking density of young chicks is also an important factor affecting performance. A reasonable breeding density can not only reduce the cost of feeding, but also promote the growth and development of earthworms, reduce the occurrence of diseases and filthy beaks, licking feathers, etc., improve the survival rate of the young chicks, and the growth and development are neat. Therefore, according to the specific conditions such as the age of the day and the temperature, reasonably arrange the breeding density. In general, in the same rearing area, the winter can be raised in excess, and in the summer, the number of raises can be reduced by 10% to 15%. At the same time, the age can be small and dense, and the old age can be sparse. some. In short, how to determine the specific rearing density should be determined according to the specific circumstances, generally 1, 2, 3, and 4 weeks of age and commercial quail and species breeding per square meter were 150,100,80,60 and 55 and 42 respectively. Only, the number of extreme rearings were 200, 120, 100, 80, 66 and 48 respectively.
