摘要
在现代养猪生产中,除品种、饲料、饲养管理、疫病防治等几大因素可对猪的生产性能构成巨大影响外,养猪的外部环境因素(季节———温度环境)也制约着猪的生产性能发挥,给养猪生产带来巨大影响。优良品种其生产潜力的充分发挥,不仅需要优质全价饲料、健康的状况,同时还必须有适宜的生活和生产环境。如果环境条件不适宜,则优良品种的遗传潜力不能充分发挥,饲料的转化率低,猪的抵抗力、免疫力、繁殖能力下降,发病和死亡率提高,造成生产的巨大损失。
In modern pig raising industry,besides internal factors including breed,feed,feeding sysytem and disease control could greatly influence pig performance,other external factors(season -environment temperature)also restrict the improvement of pig performance,which produce vital effect on pig raising industry.In order to fully gain the production potential of excellent breed,not only the high quality feed and heaythy constitution is demanded,but also the optimum living and producing condition should be guaranteed.Other wise,its outstanding genetic potential couldn’t be completely give out;feed conversion rate (FCR)would be lowered;pig disease resistance ability,immunity and reproductivity shrunk while the disease incidence and mortality increased,which causes enormous loss to pig industy.
