荒漠草原混牧牛羊的放牧行为特征
Grazing behavior traits of cattle and sheep on mixed pasture in desert steppe
摘要
Abstract
Understanding of the behavioral traits of mixed-grazed livestock in desert steppe is important when planning the sustainable use of grassland resources.This study was carried out in a desert pasture with mixed-grazing by cattle and sheep in Boarder Yellow Banner,Xilingol League,Inner Mongolia Autonomous Region,China.Four cattle and eight sheep from the herds were selected to wear GPS collars containing three-axis acceleration sensors,and their temporal dynamics of grazing time(GTIME)and grazing overall dynamic body acceleration(GODBA)were analyzed.From the data,we explored the response patterns of grazing behavior traits of mixed-grazed cattle and sheep to the monthly changes in the grassland vegetation.GTIME and GODBA showed significant positive correlations in cattle and sheep grazed together on desert steppe pasture(R2>0.60).Further,the results showed opposite patterns in the GODBA responses of cattle and sheep.Cattle were positively stimulated by above-ground biomass(P<0.05),while negatively stimulated by Shannon index(P<0.01).Sheep were negatively stimulated by above-ground biomass and the proportion of poisonous herbage(P<0.001),while positively stimulated by Shannon index and forage crude protein content(P<0.001).In addition,the 24-hour behavioral patterns of cattle and sheep on mixed pasture both exhibited"multimodal"characteristics,and tended to shrink with the month changes.Furthermore,there were significant differences between cattle and sheep in acceleration intensity during different types of activity,with the acceleration intensity of sheep being significantly higher than that of cattle(P<0.05).关键词
