荒漠草原饮水半径和饮水量对羊生产性能的影响研究

Study on the effects of drinking water radius and water intake in desert steppe on the productive performance of sheep

为了对羊的饮水量、饮水半径、饮水次数、体重增加量等供水指标展开研究,试验以内蒙古荒漠草原为背景,在野外试验基础上,利用对照比较的方法分析不同饮水量水平、不同饮水半径处理对羊体重增加量的影响。结果表明：最优饮水半径为4km,日饮水3次是效益最高的饮水方式,合理日饮水量为4,5月份4～5kg/d,6—9月份6～8kg/d,10,11月份5～6kg/d。

To extensively study the water supply indexes of sheep, such as water intake, drinking water radius, drinking water times and the weight gain, the desert steppe of Inner Mongolia was selected as the background in the test. Based on the field experiment, a controlled compar- ative method was used to analyze the effects of the treatments containing different water intake levels and drinking water radii on the weight gain of sheep. The results showed that the optimal drinking water radius was 4 km, and drinking water throe times daily was the most profitable way of drinking water, and reasonable daily water intake was in 4 to 5 kg/d in April and May,6 to 8 kg/d from June to September,and 5 -6 kg/d in October and November.
