Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

This document is part 2 of GB/T 41441 "Good production environment for large-scale livestock and poultry farms". GB/T 41441 has issued the following part.

--- Part 1: Site requirements.

--- Part 2: Technical requirements for livestock and poultry houses.

Introduction

The good production of large-scale livestock and poultry farms is to carry out good production through the whole production process of pre-production, mid-production and post-production in the production process of livestock and poultry breeding.

Behavior control, improve the level of cleaner production in the livestock and poultry breeding industry, emphasize the importance of pollution prevention, and at the same time in the production process to "energy saving, consumption reduction, pollution reduction and efficiency" is the goal to reduce the energy consumption and the generation and discharge of pollutants in the whole process of livestock and poultry production, and reduce the pollution of waste to the environment.

It is beneficial to realize the sustainable development of livestock and poultry breeding and provide safe and healthy green livestock and poultry products for human beings. GB/T 41441 aims to establish universal Specifications for good production environment site selection and livestock and poultry house technology applicable to large-scale livestock and poultry farms are proposed to consist of two parts.

--- Part 1: Site requirements. The purpose is to improve the production environment through reasonable site selection, planning and design of large-scale livestock and poultry farms.

Carry out requirements and specifications to reduce the negative impact of the environment and improve the environmental benefits of livestock and poultry farms by means of prevention.

--- Part 2: Technical requirements for livestock and poultry houses. The purpose is to improve the good production environment through the technical conditions of large-scale livestock and poultry farm production areas. compliance with the requirements and specifications, through the control of the building and structure of the production area, sports fields, environmental regulation, excrement cleaning, water supply and drainage, sanitation and disinfection and management methods to effectively reduce the environmental pollution caused by the livestock and poultry breeding process.

Livestock and poultry houses are an important part of animal breeding, the place where livestock and poultry are produced and lived, and the main body of livestock and poultry farms. The environmental quality in livestock and poultry houses is directly It directly affects the production performance and production efficiency of livestock and poultry, and even affects the health of animals and the quality of livestock products; at the same time, the production process and design of livestock and poultry houses Equipment, waste cleaning and collection methods, and rain and sewage collection methods directly affect the amount of waste generated and its post-treatment pressure. This document is By standardizing the relevant technologies and equipment requirements of the production technology and process used in the livestock and poultry houses, in order to ensure the production efficiency of animal husbandry Under the circumstances, effectively reducing the production of breeding waste and its environmental pollution, and realizing the clean production of animal husbandry, has ten advantages in promoting the sustainable development of animal husbandry. important meaning.
