The benefits of automated chicken cage farming

Automated egg chicken farming has the advantages of saving land, reducing environmental pollution, lowering feeding costs, improving investment utilization and labor productivity. The feeding density of automated egg chicken farming equipment can reach 4813-60 chickens? m2 , The ratio of feed to egg is 212-215:1, and the mortality rate is less than 15%. Compared with three-layer full step cage farming, it can save 63148% of land and increase labor productivity by 160% to 290%. High density stacked cage feeding of laying hens has the advantages of saving land, reducing environmental pollution, lowering feeding costs, improving investment utilization and labor productivity. It is a new intensive and efficient feeding and management mode for laying hens, which is in line with the development trend of modern laying hen production. The environmental control facility adopts a vertical ventilation wet curtain cooling system for negative pressure ventilation in the chicken coop in summer, and the wet curtain water pump is stopped in other seasons. In addition to installing a wet curtain fan ventilation system in the chick rearing house, a coal fired positive pressure and other heat evenly distributed air supply system should also be used during the low temperature period in winter to ensure the normal growth of * * * chicks. Install an intelligent data collection and environmental management self-control system in the chicken coop to achieve automatic control of lighting, ventilation, cooling, and heating inside the coop. Breeding management system [1]: The transfer and expansion of egg laying hens in stacked cages are different from those in general chicken houses due to the shape of the cage and environmental control factors. There are two ways to expand the population of laying hens during the brooding and breeding stages: one is to expand the population from one layer to the other layers, that is, the vertical expansion system; One is the horizontal expansion system, where each layer at one end expands the flock longitudinally along the chicken coop. Vertical expansion is preferred because it always occupies one or more layers, and the feeding, drinking, and cleaning systems of each layer can operate at full capacity, with high equipment and energy utilization efficiency. When expanding horizontally, the chickens are densely packed, which can achieve effective environmental control and is suitable for areas with harsh climate conditions. Due to the high and dense cage structure, it is difficult for laying hens to switch flocks, resulting in a high mortality rate. Therefore, strict operating procedures should be established and flocks should be switched at night. Feeding, manure cleaning, egg collection, and epidemic prevention in the stacked cage house are controlled by a timing device. The feeding control program is set according to the feeding amount of laying hens at different feeding periods. The feed is sent from the feeding tower to the feeding trough through pipelines and spiral devices. Chicken manure is discharged from the horizontal manure belt and the horizontal manure cleaning ditch at the end of the house, and is cleaned once in the morning and once in the afternoon. The automatic egg collection system can complete the transportation, cleaning, and disinfection of eggs. In actual production, a rail car can also be installed on the cage for manual egg collection. By connecting to the automatic dosing device of the drinking water system, it is convenient to carry out disease prevention work for the chicken flock. The stacking cage technology has a high degree of mechanization and automation, and adopts a responsibility system in production organization and management, resulting in high labor efficiency for personnel. When the egg production rate of the chicken coop is below 80%, the six rows of cages in the entire coop are managed by four people in different zones (mainly for manual egg collection), with a management quota of 15000 eggs per person. During the peak period of egg production, each person is responsible for managing 10000 laying hens. The key to the success or failure of environmental control in layered cage farming lies in the control of the indoor environment. The dense chicken body generates a large amount of heat and harmful gases, and effective environmental control measures are taken to control the house temperature and air quality. The 200000 egg chicken farm in Luoniushan, Haikou has successfully solved the environmental problem of high-density stacked cage houses in tropical areas during summer by adopting a longitudinal ventilation wet curtain cooling system. The main parameters for controlling the environment inside the chicken coop are temperature and lighting. The number of fans turned on is adjusted according to the meteorological conditions outside the coop, and mechanical ventilation is used
