Legehenne smooth farm and legehenne breeding method

Abstract

The invention relates to a legehenne smooth farm and a legehenne breeding method. On the farm, a manure release channel is arranged under a coop frame of a barton, a main extraction chimney and an auxiliary extraction chimney are arranged above the coop frame, and indoor parts of the main extraction chimney and the auxiliary extraction chimney are transparent, and lights are arranged in the indoor parts; the coop frames are symmetrically arranged at two sides of the main extraction chimney and the auxiliary extraction chimney; the lower port of the main extraction chimney extends to the middle lower part of the manure release channel, and the lower port of the auxiliary extraction chimney is close to the top of the coop frames; the width of the upper port of the manure release channel is matched with that of the coop, the lower part of the manure release channel is furled to be matched with the lower port of the main extraction chimney; and a ventilating duct is arranged under the channel, is communicated to the air inlet at one end of the coop, and uniformly distributes air to the barton through an air distributing port. The barton forms nature air flowing under the actions of air pressure and thermal pressure to ensure that air bath type directional airflow is formed in the barton, and air in the barton is consistent and fresh throughout the year; and the legehenne smooth farm has reasonable layout and complete functions, is convenient to control various environment indexes in the barton, has light disinfection burden, less health-care administration, low breeding cost, smooth whole breeding and less epidemic situations, low energy consumption and improved breeding efficiency.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a stable farm for laying hens and a method for raising laying hens. Background technique [0002] Since 1985, China's poultry egg output has been ranking first in the world. In 2006, the poultry egg output reached 29.456 million tons, accounting for more than 44.5% of the world's output. In recent years, due to the large-scale breeding industry and the rapid development of the circulation of livestock and poultry products, livestock and poultry diseases, especially avian influenza and other major diseases, have occurred frequently, which has aroused people's concern about the safety of livestock and poultry and their products. worry. The large-scale breeding of laying hens in my country has always been troubled by the threat of epidemic diseases and low production levels, making it difficult to develop stably. The main reasons are unreasonable chicken house construction, simple ...

Problems solved by technology

At present, many farms use natural ventilation and horizontal ventilation. The disadvantages are that there are too many fans, high power consumption, low wind speed, uneven air flow, inter-block environment and serious pollution. Research and development in the late 1980s The new technology of longitudinal ventilation in livestock and poultry houses has achieved great results in solving the problem of ventilation dead space in different types of livestock and poultry houses, ensuring the uniformity of airflow, reducing mutual infection between houses, and improving hygiene and epidemic prevention; 1. In terms of heating and cooling, during the "Ninth Five-Year Plan" period, two types of winter ventilation heat recovery devices, heat pipe and plate type, were researched and developed to increase the temperature of fresh air entering the room, and to a certain extent alleviate the winter ventilation and heat preservation of livestock and poultry houses. contradictions

[0004] However, the above-mentioned improvements and innovations still fail to solve the perennial problems of high energy consumption in the operation of the existing farms, high breeding costs, and difficult control of the environment in the house.
