Description
Family ranch grassland livestock production optimal management model was used to simulate the grassland supply and livestock demand, family economic status under different stocking rates senarion with collection of grassland, livestock, and economics data from Wuzhumuqin Banner and Tongliao as two types of pastoral areas in Inner Mongolia Autonomous Region. The livestock is grazing all year long in Wuzhumuqin Banner, but the livestock is grazing in summer and feeding in hovel in winter in Tongliao, which we call it as semi-farming and semi-pastoral area. The results showed that summer grassland productivity could meet the energy demand of livestock. As the temperature drops in winter and spring, the energy demand of livestock increases, and there is excessive supplementary feeding suff from December to February in the whole pastoral area, and the supplementary feeding amount from January to next January in the semi-agricultural and semi-pastoral areas is not enough to meet the maintenance needs of livestock requirement. The methane emission of herds was more in summer than in winter, and the average methane emission of herds was 3.87 kg/ day and 3.28 kg/ day in the whole grazing area and semi-farming and semi-grazing area, respectively. When the stocking rate of typical households in the whole pastoral area and semi-agricultural and semi-pastoral area was adjusted to 1.34 sheep units/ha and 1.65 sheep units/ha, the corresponding net income was 198,000 RMB and 81,000 RMB, and the net income of pasture was the highest.
