Abstract: During the upgrading of the structure of the domestic consumption and the strategic adjustment of agricultural structure, China's animal husbandry industry has developed rapidly, which leads to increasing of the demand for forage. However, the domestic supply of forage is insufficient and the safety problem is prominent. In this paper, the field investigations were conducted in Hangjinhou Banner and Dengkou county of Bayannur city, the pilot county of “grain transformation to feed”, to understand the input and output of local farmers' forage planting, the empirical research was carried out on  the influencing factors of farmers forage planting behavior by using the Logit, 2SLS and LIML models. The results showed that the forage grass planted by farmers in the survey area mainly included silage corn, alfalfa and oat grass, and the economic benefit of planting alfalfa grass was higher than other forage materials, with the net income of 22005 yuan per hectare in 2021, and higher than 4590 yuan per hectare and 12180 yuan per hectare compared with silage corn and oat grass respectively. However, the survey also found that the enthusiasm of farmers to plant forage, especially alfalfa, was not high. Further study on the influencing factors of farmers' choice of planting forage found that policy incentives, land endowment and organizational system factors had significant positive effects on farmers' behavior of planting forage. It is proposed that the government should establish a perfect land transfer market system as soon as possible to help farmers expand the scale of planting, smoothly carry out the structural adjustment of planting, increase the area of forage planting, promote the virtuous cycle of planting for breeding, solve the problem of shortage of forage in the breeding industry, and encourage all kinds of cooperatives to play the advantages of the cooperative system, help farmers reduce the input cost of planting forage, broaden the sales channels of forage, and increase the income of farmers. Countermeasures and suggestions to increase farmers' income.
