随着中国畜牧业的大力发展,肉猪饲养和禽类的养殖数量已经达到世界第一位,肉牛生产也不甘示弱,近年来,中国牛肉数量仅仅少于美国和巴西,2009年我国牛肉产量已经达到635.5万 t ,并且呈逐年增长的趋势.但是环境专家研究数据表明,畜牧业养殖产生的温室气体排放量占世界温室气体排放总量的18%以上,所以引起越来越多的人更加关注畜牧业对环境的影响,畜牧业养殖给人们带来了巨大挑战:提高肉牛的养殖效率(饲料转化率),引进和培育优良的品种,进行合理的发展可持续生态养殖,解决当前阻碍畜牧业发展的疾病预防控制.
隨著中國畜牧業的大力髮展,肉豬飼養和禽類的養殖數量已經達到世界第一位,肉牛生產也不甘示弱,近年來,中國牛肉數量僅僅少于美國和巴西,2009年我國牛肉產量已經達到635.5萬 t ,併且呈逐年增長的趨勢.但是環境專傢研究數據錶明,畜牧業養殖產生的溫室氣體排放量佔世界溫室氣體排放總量的18%以上,所以引起越來越多的人更加關註畜牧業對環境的影響,畜牧業養殖給人們帶來瞭巨大挑戰:提高肉牛的養殖效率(飼料轉化率),引進和培育優良的品種,進行閤理的髮展可持續生態養殖,解決噹前阻礙畜牧業髮展的疾病預防控製.

With the vigorous development of China's livestock ,hog raising and poultry farming have reached the number one of the world ,beef cattle production to be outdone ,only less than the amount of beef in America and Brazil .In 2009 ,beef production in China reached 6 .355 million ton ,and the trend of increasing year by year .But environmental experts research data showed that animal husbandry breeding produced gas emissions account for more than 18% of the world’s greenhouse gas emissions ,so more and more people paid more attention to the animal husbandry of the impact on the environment .Livestock farming had brought great challenges to per‐sons improve the breeding of beef cattle efficiency (feed conversion ratio ) ,introduction and cultivation of good varieties ,the rational development of sustainable eco‐farming ,solve disease prevention and control which was the current obstacles of animal husbandry development .
