Land selection and house construction for Hyline brown
1. Hailan brown shell laying site selection. First, it is considered to be in line with local land use planning, followed by epidemic prevention, high terrain, and away from towns, trunk roads, and railways.
More than 1000m, no more than 500m from the secondary traffic roads and residential areas, no chemical factories, mining plants, tanneries, meat processing plants, slaughterhouses, garbage and sewage treatment plants within 2000m.
2. Hailan brown shell layer chicken infrastructure. There is a stable clean water source, and the water quality should reach the “Standards for Drinking Water Quality of Non-polluted Foods and Livestocks (NY 5027-2001)”. The power supply is guaranteed, the transportation is convenient, and a dedicated lane is directly connected.
3, Hailan brown shell hens moderate scale, construction of a single field inventory rules 10,000 to 50,000. The scale is too large, which is not conducive to all-in and all-out, increasing the difficulty of management; the scale is too small, increasing the proportion of technology and management costs in the total cost, and reducing the benefits. The scale of 10,000 to 50,000 breeding is the main trend of laying hens in China, and the small-scale is gradually phased out. The large-scale one-time investment is too large.
4, Hailan brown shell laying hens scattered layout. Controlling the spread of epidemics has become the key to the effectiveness of laying hens. The pattern of densely populated farming communities has been negated because of the difficulty of epidemic prevention. Advocating a moderately dispersed layout, maintaining proper spacing between chicken farms is conducive to establishing a bio-safety system, improving epidemic prevention and reducing the risk of disease.
5, Hailan brown shell chicken hen house type. It is recommended to have two kinds of chicken houses with open and closed windows. Among them, closed chicken houses have the best effect. If there are conditions, it is best to build closed chicken houses. Window-opening chicken houses are relatively inexpensive to produce, and natural lighting and natural ventilation can be fully utilized in daily production, saving production electricity, and production and running costs are lower than closed chicken houses. However, the open house is susceptible to external environmental conditions. The insulation performance of the house is not as good as that of the closed house. The production level such as feed compensation, egg production performance, and the rate of death of the chicken is not as good as that of the closed house. Although the daily production and operation cost of the enclosed chicken house is high, the chicken house has a good microclimate control, the air quality in the chicken house is good, the living environment of the chicken group is suitable, the production level is high, and the death rate is low.
There are two rows of three walkways and three rows of four walkways in the open house. The enclosed chicken house can be arranged in three rows of four walkways and four rows of five walkways. The matching cage can be used in 3 steps or 4 steps.
6, Hailan brown shell egg equipment. It is recommended that the hot blast stove heat preservation brooding, nipple drinking water, mechanical feeding, mechanical decontamination, fan wet curtain cooling, in addition to the conditions must also be equipped with emergency power generation equipment.
