    the 18th Report of the Party's

    in

    2012,

    made a strategic decision to

    vigorously promote the construction of ecological civilization, and increase the intensity of natural ecosystems and environmental protection. Strengthen water, atmosphere, soil and other pollution prevention and control.

    2015

    , the Fifth Plenary Session of the 18th Central Committee, the strengthening of ecological civilization construction was first written into the national five-year plan,

    ecological development has been an important measure of future development, do a good job in pollution prevention and control, from the root causes to solve the pollution problem is an important way to achieve ecological development;

    the pig industry plays a major role in animal husbandry,

    with the

    world

    population growth and

    improvement in people's living standards, global pork consumption has grown strongly in the past 20



    years, at a rate of nearly 50%

    the growing environmental challenges brought about by the pig industry

    , with the improvement and implementation of national environmental legislation, many provinces and cities have developed more stringent breeding regulations. Is raising pigs sure to bring pollution? Europe, which has a similar land and population situation to ours, has done a better job of controlling pig pollution: the pig kingdom of Denmark has an area of 43,000 square kilometers

    km but can produce 30 million pigs a year (of which 10 million export weight

    7-15

    kg). And those who have been to Denmark will certainly be impressed by the green mountains and waters there.

    . RVg

    show that pollution can be avoided with comprehensive measures. Pig-breeding pollution is mainly caused by the imbalance of amino acids in the daily material to cause a large amount of discharge of nitrogen and phosphorus in feces and phosphorus, which causes the

    of environmental pollution of subspecies,

    nitrogen pollution in terms of weight is more than ten times the former. The appropriate addition of amino acids in the grain

    ,

    in accordance with the amount of digestible amino acidneeds reasonable preparation of low-protein grain

    ,

    is of great significance to reduce environmental pollution
