Egg breeding period breeding management
After the chicks have been grown for 5 to 6 weeks, they will be transferred from the brooding room to the breeding room until 18 to 20 weeks before they can be raised on the cage. How do you manage the rearing layer of laying hens? 1 Preparation before entering the breeding room 1.1 Environmental disinfection : To conduct a comprehensive weeding disinfection around the breeding room, high-pressure room washing, and spraying or soaking the ground with a 10% to 20% lime solution. After the drying, the indoor floor is cleaned with clean water and dried for use. 1.2 Disinfection of Drinking Water Appliances: Leveling and Breeding, drain the water from the drinking line, and add acetic acid 7 days before entering the room. The concentration is 10% to 20%. The chicken is drained before entering the room, and the cage is raised into a water disinfectant to disinfect and clean it. . 1.3 Sterilization in the rearing room: The flat-raised bred ground is made of rough grass for mat grass, about 5cm in pad, and slightly thicker in winter. Adjust the height of the drinking water line, and check whether the nipple of each waterer is leaking. The water leakage must be repaired immediately. The cage raises all the equipment into the room and closes the doors and windows. Formalin is used for every cubic meter of 15-40 ml: 7.5-20 g of high manganese. Potassium fumigation for more than 12 hours, then open the doors and windows for ventilation. 2 Precautions for Turning Groups 2.1 Turning groups to prevent stress: Add electrolytes or vitamins to the chicken feed 3 days before the switch. Feed conversion is a transitional process. The first day of brooding and half of the growing season are expected to be reduced to 40% on the second day of brooding and to 20% on the third day. 2.2 Turnover: Choose sunny weather during the winter in the group, and cool in the morning and evening in summer. As far as possible in the end of a day, and the weight of the same size for easy management. Light weight can be kept in the brooding room for a week. Prevent people from injuring chickens during the transition. 2.3 Feeding and management at the initial stage of the transfer: After the chicks are transferred to the group, they must adapt to changes in the environment and must prevent them from bursting. Pay attention to whether or not the chickens can drink water. After a week of familiarity with the chickens, the normal operation can be performed according to the broiler management techniques. 3 Limit Feeding and Weight Control 3.1 Limit the purpose of feeding, prevent young chickens from eating too much and increase fat accumulation, so as to ensure the normal growth and development of chickens and the reasonable needs of chickens for nutrients during egg formation. 3.2 Restricted rearing methods, limited feed intake, 10% to 20% reduction in free intake, dietary energy and protein restrictions, increased cellulose, decreased energy, decreased protein and amino acid content, time constraints on eating, Eat regularly every day. 3.3 Limiting feeding effects: Slightly inhibit growth, prevent premature sexual maturation (premature production), control weight gain, maintain standard open body weight, reduce feed intake, thereby saving feed, reducing body fat accumulation, and preventing egg production The chicken developed fatty liver syndrome. 3.4 Weighing: Each weighed 5% of the chickens was weighed, and the control standard checks whether the amount of feed is appropriate, in order to decide to adjust the feeding amount next week and check the uniformity of the chicken group weight. 4 lighting control: the first day of the group should be 15m incandescent lamp lighting every 5m2 for the whole night, the purpose is to prevent the frightened crowd. After the lights are turned off the previous week, pay close attention to the flock of chickens to prevent frying and gathering. According to the sound of the chicken's breathing, judge whether the chickens have developed a cold after they have switched to groups. Light is maintained for 8 to 12 hours of constant light 18 weeks ago, and open or semi-open houses are dominated by natural light. 5 Nutrition 6-8 weeks with growth materials, 8-15 weeks with growth materials, 15-18 weeks with open materials, each refeed must be fed. 6 Other management measures 6.1 Density: Flat raising (including online cage raising), raising 10 chickens per square metre, and raising 270 to 280 cm2 per cage. 6.2 Feeding uniformity: regular inspection, found that some tanks have more material accumulation, some have no leftovers, should be evenly opened to prevent some chickens from eating too much, some chickens are not eating enough, so that the development of chickens neat. 6.3 To ensure the regularity of the flock: Always pay attention to picking out the smaller and weaker chickens for separate care and feeding more feed properly so that they can catch strong chickens. 6.4 Pay attention to ventilation, change dunnage: Pay attention to ventilation, promote the development of the heart and lung system, and constantly change the litter, to ensure indoor cleanliness. The bedding wetting by water should be replaced immediately. 6.5 Disease Prevention Law: 40 to 60 days of age to do a good job of prevention and treatment of staphylococcal disease, coccidiosis prevention and control work during the rainy season, raising bred chickens should pay attention to the timely administration of medication, medication can not be a single, should be replaced frequently. There are many mosquitoes in summer, and chick pox seedlings should be prepared in advance. In strict accordance with the immunization program, the chicken Newtown vaccine was immunized without losing the opportunity. The sanitation and epidemic prevention work of chicken coops is often done, and weekly disinfection of chicken coops with disinfectants is insisted. 6.6 Prepare baskets 18 to 20 weeks ahead of schedule to avoid delays in getting caged and reduce initial stress. And to be immune to egg cut syndrome. China Agricultural Network Editor
