Abstract: Agriculture contributes significantly to GDP. Grassland agriculture, as an important part of modern agriculture, connects the grassland with livestock, and maximizes plant productivity and animal product yield while minimizing environmental disturbance. Grassland agro-ecosystems incorporate four production components, and the animal production component is one of these and also an important criterion in determining production efficiency. Based on data for 31 provinces and cities in China from 1992 to 2011, this issue was analyzed and conclusions drawn. Firstly, according to national and provincial data, animal production and the contribution of agriculture to GDP have increased. The data basically can be divided into three stages from 1992 to 2005, 2005 to 2006, and 2007 to 2011 which align with successive agricultural policies. Secondly, from the perspective of the emerging trends for animal production, the major agricultural provinces have a higher contribution to GDP from animal production. For other cities, due to either a small contribution of animal husbandry to economic development or low animal product returns, contribution of animal production to GDP is relatively small. Thirdly, the fastest-growing areas for animal production are also in most cases major agricultural provinces. This may be due production of stock feed required to develop animal production. Fourthly, animal production GDP and other economic indicators are positively correlated. Because of different endowment of resources and different policies, the situation differs in different provinces and cities. This suggests China’s grassland agriculture still has many problems. In order to support the development of agriculture, the government should consultatively review policy, and vigorously support the development of grassland agriculture.
