Why does the development of cattle industry meet the objective requirements of grain-saving animal husbandry and China's national conditions?

The development of cattle industry conforms to the objective requirements of grain-saving animal husbandry and China's national conditions, mainly for the following reasons:

1. Shortage of food resources: China has a large population and relatively few per capita food resources. The development of cattle industry can make full use of non-food resources such as straw and effectively alleviate the food pressure.

2. High feed conversion efficiency: cattle are ruminants, which can efficiently utilize non-food resources such as straw and convert them into high-quality meat and dairy products. This is helpful to improve feed conversion efficiency and save food resources.

3. Promote the adjustment of agricultural structure: the development of cattle industry can promote the adjustment of agricultural structure and promote the development of agriculture in a diversified and efficient direction. At the same time, the combination of raising cattle and planting can realize the comprehensive utilization of agricultural resources and improve the overall efficiency of agriculture.

4. Increase farmers' income: Cattle industry can provide farmers with a stable source of income, such as selling beef, milk and other products. In addition, the cattle industry can also promote the development of related industries, such as leather and medicinal materials, and further increase farmers' income.

5. Adapt to rural economic development: In rural areas, cattle industry has great market demand and potential. Developing cattle industry can meet the needs of rural economic development and promote the prosperity of rural economy.

To sum up, the development of cattle industry conforms to the objective requirements of grain-saving animal husbandry and China's national conditions, which is conducive to alleviating food pressure, improving agricultural benefits, increasing farmers' income, and also conducive to agricultural restructuring and rural economic development.
