高温高湿季节西南地区中小规模猪场环控目标达成策略
Strategies for Achieving Environmental Control Goals for Small and Medium Scale Pig Farms in Southwest China During the High Temperature and Humidity Season
摘要
Abstract
In the hot and humid summer,the abnormal condition was very common that the ambient temperature and humidity exceed the high limit value in small and medium scale pig farms,led to obvious heat stress reaction of pigs at all stages,which was mainly manifested in a series of production problems such as decreased semen quality of boars,decreased feed intake of sows at different stages,insufficient farrowing capacity of farrowing sows,decreased lactation performance of lactating sows,low estrus and conception rate of weaned sows,and serious respiratory diseases of piglets.By digging and analyzing the key factors causing the above adverse effects,it was found that the longer time of temperature and humidity exceeding the maximum limit value in the pig house environment was mainly due to the combination of factors such as low elevation of pig farms,irrational construction of the environmental control de-sign,improper use of environmental control equipment,and sloppy production management.In order to reduce the occurrence of unfa-vorable production conditions and reach the goal of environmental control in the pig house in the high temperature and high humidity season of small and medium scale pig farms in Southwest China,the concepts and measures of choosing a higher altitude location to build pig farms,scientifically designing and standardizing the construction of pig house environmental control system,scientifically and efficiently using the environmental control equipment,and strengthening the management of the production,etc,were used to achieve the goal of better environmental control in the pig house under the high temperature and high humidity conditions.关键词
