[Effects of planting rubber and crops on the keeping number of livestock and poultry in the Naban River Watershed National Nature Reserve].

A total of 207 householders from 13 natural villages in the Naban River Watershed National Nature Reserve were chosen for a systematic survey on the farming and livestock husbandry, aimed to evaluate the effects of planting rubber and crops on the keeping number of livestock and poultry in the study area. The livestock and poultry bred in the Reserve were mainly buffalo, Yunnan Yellow cattle, small-eared pig, Chahua chicken, and a few Banna game fowls. Exotic breeds were very limited. From 1991 to 2008, the planting area of rubber increased year by year, giving negative effects on the corn, rice, and cash crop production as well as the keeping number of livestock and poultry. Planting rubber had significant negative effects on the keeping number of buffalo and small-eared pig. The families planting rubber kept significantly less buffalo and small-eared pig, as compared to those not planting rubber. The planting areas of corn, rice, and cash crops had positive effects on the keeping number of buffalo, Yunnan Yellow cattle, and small-eared pig, and the total planting area of the crops had active effects on the keeping number of buffalo and Chahua chicken. The development of rubber production led to an obvious change in land use pattern, which in turn had significant effects on the keeping number of livestock and poultry. With the increasing rubber planting area year by year, the local livestock husbandry would be restrained.
