摘要
在青海省三角城种羊场对妊娠后期放牧藏羊进行了补饲试验,结果显示:补饲颗粒料组的藏羊繁殖成活率比对照组提高3.78%,羔羊死亡率比对照组减少2.37%,差异显著(P<0.05)。平均毛长比对照组长6.01cm,公羔和母羔出生重分别比对照组高0.56kg、0.44kg,羔羊细毛、两型毛和总毛量比对照组分别多328.3根、327.4根和628.8根。差异均极显著(P<0.01)。说明放牧藏羊妊娠后期补饲颗粒料对母羊繁殖性能、羊毛生长、羔羊出生重有显著效果。补饲舔砖组的藏羊平均毛长比对照组长4.06cm,差异极显著(P<0.01),公、母羔出生体重分别比对照组高出0.06kg、0.3kg。母羔出生体重,差异显著(P<0.05)。由于补饲舔砖组部分羊只出现腹泻对试验结果有一定影响。
The compensatory experiment was done on Tibetan sheep in late period of pregnancy at Sanjiao cheng breed sheep farm in Qinghai province. The results showed that reproduction survival rate at supplied pellet feed group increased by 3.78 % compared with control group, the lamb death rate reduced by 2.37 % , and difference was significant （ P 〈 0.05 ） Average wool length were longer 6.01cm than control group. The birth weight of both rams and the ewe lambs were higher 0.56kg,0.44kg than those at control group, and the production of the lamb fine, dimmer and overall wool were more than 328.3,327.4 and 628.8 compared with control group. The difference is extremely significant differences（ P 〈 0.01 ）. These results showed that compensatory, pellet feed had the apparent effects on production performance, wool growth and the weigh of yeanling birth. Average wool length of Tibetan sheep in the test groups fed nutritive lick brick increased by 4.06 compared with the control group,the difference was remarkable significant（ P 〈 0.01 ） ,birth weighs of the ram and the ewe lamb were higher 0.06kg,0.30kg than control group, and the late had significant difference（ P 〈 0.05）. The test results were influenced by partial sheep diarrhea with nutritive lick brick.
