Abstract: In order to evaluate the influence of warm shed feeding manner on weight and wool production performance of Ordos fine wool sheep in cold season, the selected basic ewe, reserved ewe, gimmer hogg and ram hogg were randomly divided into experimental group and control group, respectively. All of the experimental groups fed inside the warm shed at night from December 7 of 2012 to January 31 of 2013, whereas the control groups fed outside the warm shed at the same time. The daily temperature inside and outside the warm shed during the warm shed experiment in cold season were recorded and the changes of body weight of experimental groups and control groups in different sheep flocks were determined and analyzed. After the warm shed experiment was finished, all of the sheep fed to June of 2013. At the end of the experiment, the yield, length and fineness of wool of experimental groups and control groups in basic ewe, reserved ewe and gimmer hogg were determined and analyzed,respectively. The results showed that during the warm shed experiment in cold season, the average temperature at night inside the warm shed was 9.76 ℃ higher than that outside the warm shed, and the minimum temperature inside the warm shed was 14.10 ℃higher than that outside the warm shed. The lose weight of experimental groups in basic ewe, reserved ewe and gimmer hogg were3.57, 2.98 and 2.74 kg less than that of the corresponding control group, and the weight gain of experimental groups in ram hogg was 3.08 kg higher than that of the control group during the warm shed experiment. The wool yield of experimental groups in basic ewe, reserved ewe and gimmer hogg were 0.22 kg（P〉0.05）, 0.11 kg（P〈0.05） and 0.59 kg（P〉0.05） higher than that of the control groups, respectively. The wool length of experimental groups in basic ewe, reserved ewe and gimmer hogg were 0.40 cm（P〉0.05）, 0.31 cm（P〉0.05） and 0.25 cm（P〉0.05） higher than that of the control groups, respectively. The wool fineness of experimental groups in basic ewe, reserved ewe and gimmer hogg were 0.01 μm（P〉0.05）, 0.09 μm（P〉0.05） and 0.24 μm（P〉0.05） higher than that of the control groups, respectively. The results indicated that warm shed feeding manner could effectively prevent the weight loss of Ordos fine wool sheep in cold season and increase the yield and length of wool and decrease the fineness of wool.
