为评价冷季暖棚饲养方式对鄂尔多斯细毛羊体重及产毛性能的影响,将选取的基础母羊、后备母羊、育成母羊、育成公羊分别随机分成试验组和对照组。各试验组于2012年12月7日—2013年1月31日,夜间圈入暖棚内饲养,对照组夜间在圈外饲养。记录冷季暖棚试验期间暖棚内、外夜间气温,比较各试验组及对照组在冷季暖棚试验期间的体重变化。冷季暖棚试验结束后,试验羊只继续饲喂至2013年6月初。试验结束时,分别测定并比较基础母羊、后备母羊、育成母羊的试验组及对照组产毛量、羊毛长度、羊毛细度。结果表明,冷季暖棚试验期内,圈内、外夜间平均气温相差9.76℃,圈内、外最低气温相差14.10℃;基础母羊、后备母羊、育成母羊试验组体重分别比对照组少下降3.57、2.98、2.74 kg,育成公羊试验组体重比照组多提高3.08 kg;基础母羊、后备母羊、育成母羊的试验组产毛量分别比对照组增加0.22 kg(P>0.05)、0.11 kg(P<0.05)、0.59 kg(P>0.05);基础母羊、后备母羊、育成母羊的试验组羊毛长度分别比对照组增加0.40 cm(P>0.05)、0.31 cm(P>0.05)、0.25 cm(P>0.05);基础母羊、后备母羊、育成母羊试验组羊毛细度均比对照组细,且细度分别降低了0.01μm(P>0.05)、0.09μm(P>0.05)、0.24μm(P>0.05)。结果提示,冷季暖棚饲养方式可有效防止鄂尔多斯细毛羊掉膘,并可提高产毛量,增加羊毛长度,降低羊毛细度。
為評價冷季暖棚飼養方式對鄂爾多斯細毛羊體重及產毛性能的影響,將選取的基礎母羊、後備母羊、育成母羊、育成公羊分彆隨機分成試驗組和對照組。各試驗組于2012年12月7日—2013年1月31日,夜間圈入暖棚內飼養,對照組夜間在圈外飼養。記錄冷季暖棚試驗期間暖棚內、外夜間氣溫,比較各試驗組及對照組在冷季暖棚試驗期間的體重變化。冷季暖棚試驗結束後,試驗羊隻繼續飼餵至2013年6月初。試驗結束時,分彆測定併比較基礎母羊、後備母羊、育成母羊的試驗組及對照組產毛量、羊毛長度、羊毛細度。結果錶明,冷季暖棚試驗期內,圈內、外夜間平均氣溫相差9.76℃,圈內、外最低氣溫相差14.10℃;基礎母羊、後備母羊、育成母羊試驗組體重分彆比對照組少下降3.57、2.98、2.74 kg,育成公羊試驗組體重比照組多提高3.08 kg;基礎母羊、後備母羊、育成母羊的試驗組產毛量分彆比對照組增加0.22 kg(P>0.05)、0.11 kg(P<0.05)、0.59 kg(P>0.05);基礎母羊、後備母羊、育成母羊的試驗組羊毛長度分彆比對照組增加0.40 cm(P>0.05)、0.31 cm(P>0.05)、0.25 cm(P>0.05);基礎母羊、後備母羊、育成母羊試驗組羊毛細度均比對照組細,且細度分彆降低瞭0.01μm(P>0.05)、0.09μm(P>0.05)、0.24μm(P>0.05)。結果提示,冷季暖棚飼養方式可有效防止鄂爾多斯細毛羊掉膘,併可提高產毛量,增加羊毛長度,降低羊毛細度。

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 were 3.57, 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 0.01μm (P>0.05), 0.09μm (P>0.05) and 0.24μm (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.
