本试验旨在研究饲粮中蛋氨酸水平对繁殖期蓝狐繁殖性能的影响。选择健康雌性初产蓝狐150只,随机分为5组,每组30个重复,每个重复1只蓝狐,均为单笼饲养。Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ组分别饲喂在基础饲粮中添加0.20%、0.45%、0.70%、0.95%和1.20%蛋氨酸的试验饲粮。试验期为2014年2月10日至2014年5月31日。结果表明：Ⅱ、Ⅲ和Ⅳ组蓝狐最先开始发情,也最早结束,Ⅰ和Ⅴ组蓝狐发情时间稍晚。受配率、受胎率均以Ⅱ组最高,Ⅱ组受配率分别比Ⅰ、Ⅲ、Ⅳ和Ⅴ组高出17%、3%、10%及14%。窝产仔数和初生个体重各组间差异不显著( P>0.05)；初生窝重随着饲粮蛋氨酸水平的升高呈现先升高后降低的趋势,并且Ⅰ和Ⅱ组显著高于Ⅴ组( P<0.05)；Ⅱ组初生成活率极显著高于Ⅴ组( P<0.01)。由此得出,饲粮中添加0.45%蛋氨酸,即饲粮中蛋氨酸水平为0.98%时,可满足繁殖期蓝狐对蛋氨酸的需要。
本試驗旨在研究飼糧中蛋氨痠水平對繁殖期藍狐繁殖性能的影響。選擇健康雌性初產藍狐150隻,隨機分為5組,每組30箇重複,每箇重複1隻藍狐,均為單籠飼養。Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ組分彆飼餵在基礎飼糧中添加0.20%、0.45%、0.70%、0.95%和1.20%蛋氨痠的試驗飼糧。試驗期為2014年2月10日至2014年5月31日。結果錶明：Ⅱ、Ⅲ和Ⅳ組藍狐最先開始髮情,也最早結束,Ⅰ和Ⅴ組藍狐髮情時間稍晚。受配率、受胎率均以Ⅱ組最高,Ⅱ組受配率分彆比Ⅰ、Ⅲ、Ⅳ和Ⅴ組高齣17%、3%、10%及14%。窩產仔數和初生箇體重各組間差異不顯著( P>0.05)；初生窩重隨著飼糧蛋氨痠水平的升高呈現先升高後降低的趨勢,併且Ⅰ和Ⅱ組顯著高于Ⅴ組( P<0.05)；Ⅱ組初生成活率極顯著高于Ⅴ組( P<0.01)。由此得齣,飼糧中添加0.45%蛋氨痠,即飼糧中蛋氨痠水平為0.98%時,可滿足繁殖期藍狐對蛋氨痠的需要。

This experiment was conducted to study the effects of dietary methionine level on reproductive per-formance of blue foxes ( Alopex lagopus) in reproductive period. One hundred and fifty healthy female blue fo-xes were randomly assigned into 5 groups with 30 replicates per group and 1 fox per replicate. The blue foxes in groupsⅠ,Ⅱ,Ⅲ,ⅣandⅤwere fed a basal diet supplemented with 0.20%, 0.45%, 0.70%, 0.95% and 1.20% methionine, respectively. The formal test lasted from February 10th 2014 to May 25th 2014. The re-sults showed as follows: the beginning of oestrus time of blue foxes in the groups Ⅱ, Ⅲ and Ⅳ was ad-vanced, and ended earlier. The beginning of oestrus time in the groupsⅠandⅤwas later. The highest values of breeding rate and conception rate were all found in the group Ⅱ, and the breeding rate in the group Ⅱ was 17%, 3%, 10% and 14% higher than that in the groups Ⅰ, Ⅲ, Ⅳ and Ⅴ, respectively. The differences in little size and birth weight among groups were not significant (P>0.05). The litter weight at birth showed a trend of decrease after the first increase as the dietary methionine level increasing, and the litter weight at birth in the groups Ⅰ and Ⅱ was significantly higher than that in the group Ⅴ ( P<0.05) . The survival rate in the group Ⅱ was significantly higher than that in the group Ⅴ (P<0.01). In conclusion, when the diet supple-mented with 0.45% methionine, which the methionine level in the diet is 0.98%, can meet the need of blue fo-xes in reproductive period.
