Breeding chicken breeding technology Dietary transition From the brooding period to the breeding period, the replacement of feed is a big turning point. Feed replacement is based on body weight and toe length. If the target is reached, the feeds will be changed after 7 weeks of age, and 1/3, 1/2, and 2/3 of the young chicks will be used to replace the brooding materials respectively. The replacement period is one week. If the standard is not reached, the chicks can continue to feed the chicks. Until reaching the standard. If you do not meet the standard in the long term, you should find out the reason. Restricted rearing Prevention of overfeeding of chickens during the rearing period results in overweight or overweight laying hens. During this period, the necessary quantitative restrictions or limitations on energy and protein levels are imposed. Reduce feed consumption, control weight gain, ensure normal fat accumulation, develop healthy, well-developed, well-developed spare chickens, prevent precocity, and reduce slaughter rate during the laying period. Restricted use of more limited methods, first of all should master the normal feed intake of chickens, reduce the amount of feed to 90% of normal feed intake, and ensure the quality of feed. Weigh once every 1 to 2 weeks, according to 1% to 5% of chickens, not less than 50 to test the effect of limited feeding. When the rate is lower than the standard, feed restriction will be stopped; Ensure that each chicken's intake, drinking position, slot material evenly. When the flock is stressed by injections, severe illnesses, diseases, and high temperature, it should be restored to free-feeding. Breeding chicken management techniques Suitable density Regardless of whether it is on the Internet or cage care, it is necessary to maintain a suitable density in order to make individual development even. On the Internet, 12 to 15 eggs per square metre are raised; when caged, each chicken has 270 to 280 square centimeters of cages and about 8 centimeters of feed intake and drinking water length. Sexual maturity control Sexual maturation is too early, it will start early, produce small eggs, sustained high yield for a short time, premature aging, egg production decreased; if sexual maturity is late, delayed production time, reduced egg production. Therefore, we must control sexual maturity and achieve timely production. The main method of controlling sexual maturity is to control light. Especially after 10 weeks of age, light exposure is increasingly sensitive to sexual maturation in broiler chickens. The bred chicken light management principle is that the light hours should be reduced from long to long, or kept constant, and the length of light cannot be increased. Generally 8 to 10 hours, the light intensity should be strong and weak. Temperature control As the broiler grows with age, the temperature in the house should gradually decrease. Excessive temperature will weaken the chicken mass. Ventilation control Breeding chickens grow fast and produce more harmful gases. Breeding chickens should undergo 3 moults at 7-8 weeks, 12-13 weeks, and 18-20 weeks. During the moult, the feathers and dust in the chicken house fly around with the chicken's activity and other factors. Therefore, it is necessary to strengthen ventilation and keep the air in the house fresh. Prevention Breaking scorpion is an important means to prevent scrofula. It should cooperate with measures to improve the home environment, reduce the rearing density, reasonably formulate the diet, and reduce the light intensity. Prior to the 14-16 weeks of age transfer, the chickens that were improperly cut or missed were supplemented. Health and Immunity Do a good job in house hygiene and regular disinfection. Detection of antibody levels, timely immunization. Before relocating, deworming. Turnover It is best to be 17 to 18 weeks old, 3 days before and after the transfer, add 50% of the multi-dimensional feed, add electrolytes in drinking water. In summer, when the morning and evening temperatures are low, during the winter when the temperature is high at noon, it is more appropriate to transfer the group. When switching to the group, reduce the light intensity in the house to reduce the stress response; grasp the chicken and do not grasp the wings to catch the legs, so as to avoid the chickens struggling, break the chicken wings, the action can not be rough, should be light to grasp.
